THE NATURE OF PSYCHOPATHOLOGY METHODS OF EVALUATION AND INTERVENTION PROLOGUE
Martin, a nine year
old caucasian boy, was referred for psychological evaluation because of his
poor performance in school, surly and hostile behavior in school and at home,
several recent thefts, frequent lying, bed wetting for the last three years,
and his inability to get along with peers, parents, siblings, or teachers. The
youngest of three boys, his brothers were three and six years older than he.
Mother had separated and divorced when Martin was about six years old, and a
year later she married a man who was ten years her senior and who had not been
married before. Martin's stepfather was an electrician who worked long hours to
provide a good income for his family. He had high expectations for his stepsons
and was extremely critical of them when they failed to measure up to his
standards. Mother, too, was demanding. In addition, she was high strung, easily
upset, a meticulous housekeeper, and a woman who had doubts about her' ability
to cope with her sons, her husband, and her home responsibilities.
Martin's brothers
seemed to get along well at home and were excellent students in school. They
excelled in athletics and were a great source of pride to their parents. Martin
began first grade doing well but, when his mother and father divorced, his
school performance fell off and he began wetting his bed at night. Martin's
mother and his brothers were very critical of him, tending to pick on Martin
and use him as a scapegoat for their own pent up frustration and anger.
Martin's academic difficulties continued, and he had to repeat the second
grade. His stepfather soon added another critical voice, and Martin reacted by
striking back with anger. He fought with his brothers, talked back to his
mother, and fabricated stories to avoid doing what his parents asked of him. At
school, he began to bully and fight younger boys and take some of their
belongings and hide them. Teachers noted that he seemed to enjoy tormenting
other children, but they could not find any effective way to stop his
aggression. Shortly before he was referred for evaluation, Martin stole a
neighbor's bicycle and some money from his mother's purse. He rode around until
long past dinner time when he was expected home. He returned the bike to the
neighbor's garage, and then entered the back door of his house, only to be
greeted by a set of worried but very angry parents. The next day, his parents
decided that Martin needed professional help.
What prompted Martin's
parents to seek the assistance of a psychologist? Was it primarily their
concern about his theft of the bike and money, or was it a reaction to a
combination of Martin's prior behaviors and his most recent actions as worrisome
indications of a serious problem? Whichever reason prompted them, their choice
rested on some vague and implicit notion about what constitutes abnormal
behavior. Although there is no single definition that we would agree upon at
this point, or, for that matter, that would completely satisfy most
professional workers, we need to define the domain of abnormal behavior in
order to have a common basis for further study. In addition, we need to grapple
with the issues and problems surrounding the classification of
children's disorders to better understand what groupings have been proposed,
how the various categories are used, and how reliable they are. Finally, as
important background information, we need to consider the scope of the problem,
the procedures used to measure the frequency of abnormal
conditions, and the sources of error associated with these measures.
What Is Psychopathological Behavior? Martin's case
illustrates that psychopathological may be easier to recognize than to define,
because psychopathology involves a number of important dimensions that are
given differential weight in arriving at a decision. His mother and stepfather
had the opportunity to evaluate Martin's behavior continually in light of his
previous personality, its appropriateness to his life circumstances, and its
effect on him. and others. They may have seen his academic decline and
bedwetting at age six as a temporary but understandable response to the stress
of his parents' separation and divorce. But the persistence of these behaviors
along with the appearance of hostile and then antisocial acts suggested that
his condition had not only worsened, but that it was also seriously affecting
the lives of others. Martin's mother and stepfather recognized his psychopathology,
but they based their recognition on multiple and vague criteria that were not
generally applicable. Therefore, we must delineate a set of criteria for psychopathological
behavior that is generalizable beyond the single case and is comprehensive
and explicit.
Abnormal behavior may
be thought of as deviant in the sense that it deviates statistically from the
normal, the usual, the most common or typical reaction found in the majority of
the population. But this criterion is limited since it implies that normality
would include behaviors that are most common, and exclude those that deviate
from the norm but that society may regard as superior, such as the behavior of
the extremely bright child or the gifted athlete. Moreover, this standard would
require that we consider within the bounds of normality the common practice of
drinking and drug abuse found among high schoolers, even though society views
these behaviors as deviant and undesirable. The fact that research indicates
that few children go through life completely free of behavioral and
adjustment difficulties implies by statistical standards that such behaviors as
temper tantrums, fears, overactivity, bedwetting, lying, and stealing are
normal (Werry and Quay, 1971; Johnson, Wahl, Martin, and Johansson, 1973). Yet
factors other than mere occurrence, such as persistence, age of onset, or the
appearance of a combination of some of these behaviors (as evidenced by Martin)
may override statistical considerations in differentiating normal from
abnormal.
In addition to these
limitations, the statistical criterion as it now stands is too broad and vague
in that it defines normal behavior in terms of what the majority does but not
in terms relative to a more specific or meaningful frame of reference. However,
the next two sections will deal with statistical criteria that take note of
cultural values and changes in behavior that occur with development.
Cultural Norms From the beginning of
civilization, people have always noted certain behaviors that were
sufficiently distinctive to be labeled abnormal. Some of these behaviors appear
to be universal, since they can be found in similar forms all over the world.
In fact, studies have shown that such psychopathological behaviors as
hallucinations, delusions, phobias, and sexual deviations are evident across
different cultures (Copeland, 1968; Al-Issa, 1969; Dohrenwend and Dohrenwend,
1974). At the same time, differences among cultures have also been reported in
both the incidence of abnormal behaviors and in the specific ways they are
expressed. Although suicide and alcoholism are well known universal phenomena,
suicide is rare among Muslims and compulsive drinking is unusual among Jews
and Chinese-Americans (Bazzoui and Al-Issa, 1966; Kleinmuntz, 1974). The
specific content of a disordered behavior, such as a delusion, also is
influenced by cultural factors. A delusion of persecution in Africa may take
the form of a fixed belief that some large, wild, and dangerous animal is out
there for the sole purpose of stalking and destroying the deluded person. In
this country, the delusional content might focus on the belief that the person
is under the electronic surveillance of foreign agents who plan to seize and
murder him. Therefore, a distinction must be made between the basic characteristics
of abnormal behavior that are constant in all cultures, and those features that
vary because of cultural differences. In general, behaviors that reduce,
interfere with, or disrupt the individual's personal and social adjustment are
considered abnormal in all societies. However, the specific form these
disruptive behaviors take, the explanation given for them, and their frequency
of occurrence vary from culture to culture. The processes and functions
underlying human behavior (normal and abnormal) are the same in all societies,
while the specific behavioral expressions are influenced largely by one's
culture. Obviously, then, what is regarded as abnormal by one culture may very
well be normal in another.
The first of our
criterion of psychopathological behavior, the cultural norm, recognizes
that every culture establishes approved standards and expectations for the
behavior of its members. Cultural norms change from time to time, but usually
there is a "lag" between the introduction of the change and its
widespread acceptance by the culture. Typically, cultural norms are more
specific and restrictive in their prohibitions in contrast to the greater
flexibility allowed for their sanctions. Moreover, there is usually more
latitude and leeway given to children in terms of what they may and may not do.
For example, our culture prohibits certain aggressive acts for adults, such as
physical assault and stealing, while similar aggressive responses are subtly
permitted for children in that they may fight, attack each other, and take
things that don't belong to them without great penalty. In addition, cultural
norms provide standards of behavior that are situationally defined. For the
adolescent, nudity is permissible in the privacy of his or her home or even in
the less than private locker room at the school gym, but it is certainly
prohibited when shopping or going to class. In this way, society identifies
certain behavior patterns and situations as acceptable.
Developmental Norms Knowledge of the
developmental process is essential in making decisions about whether a child's
behavior is normal or abnormal, although statistical averages (as we have
already noted) have their limitations for defining abnormality. We know that
most children are toilet trained before the age of three. By this standard,
Martin's bedwetting deviates significantly from developmental norms, since he
has been enuretic £or the last three years. Of course, if Martin were younger
(let us say four years old), then the deviation would be less extreme and more
difficult to categorize as abnormal. In general, the greater the deviation from
developmental norms, the higher the agreement will be with regard to the
abnormality of the behavior.
But not all
developmental deviations reflect abnormality in the sense of impaired or
insufficient progress. Some children walk unaided at an earlier age than the
norm, or have vocabularies and linguistic skills that far exceed the average.
Most, but not all, instances of rapid or early development are looked upon as
positive indications of exceptional abilities. It is at the slow end of the
continuum where developmental deviations have their major significance as a
negative criterion of abnormality.
Frequency, Intensity, and Duration For discussion
purposes, let us consider the question: Is the behavior of pulling hair from
one's head abnormal? While many might respond affirmatively, others might ask
for additional information before answering. If pulling hair occurred only
once, or at the most twice, the answer might change to a firm "no."
If, however, pulling hair was a frequent event, the answer would be
"yes." Therefore, frequency is an important
dimension in defining abnormal behaviors. In this regard, we should note that
the absence or rarity of a response may be just as significant as high
frequency. Martin's infrequent expression of warm and positive feelings is as
indicative of abnormality as is his excessive lying or his frequent bedwetting.
Another characteristic
useful in determining whether a behavior is abnormal is intensity or degree. If
pulling hair merely involved the removal of a single strand of hair rather than
large clumps, the behavior would be within normal limits. However, when behaviors
are evident in extremes of intensity or degree, they generally fall outside of
the bounds of normality and inside the range of abnormality.
Similarly, we need to
include the dimension of duration to
aid in distinguishing normal from abnormal behavior. Martin's lying and
stealing take on greater significance if they are manifest over a long rather
than a brief time span. The greater the persistence of deviant behaviors, the
more likely they are to be considered as falling within the domain of abnormality.
Intellectual and Cognitive Functioning as a Criterion In the management of
everyday affairs, we expect that normal people will function well within their
intellectual capabilities, even though most people do not operate at maximum
efficiency most of the time. A healthy fourteen year old of superior intelligence
who couldn't remember his name, address, or whereabouts would strike most of us
as odd and abnormal.
Cognitive
malfunctioning is apparent when a disparity exists between ability and actual
performance in such areas as attention, comprehension, judgment, learning,
memory, thinking, and perception. The larger the difference between a person's
capabilities and actual performance, the greater is the likelihood of abnormal
behavior. Children of average or higher intelligence who are extremely
distractible, unable to carry out simple instructions, or unable to learn the
difference between friend and foe, and those who cannot recall important,
recent, or past events illustrate cognitive impairment indicative of abnormal
behavior.
For the most part,
normal thought processes tend to be logical, coherent, organized, and
appropriate to the situation. Gross disruption and impairment of these
patterns and peculiar content, known as a thought disorder, usually
are good indicators of abnormal behavior. Wouldn't you think there was
something radically wrong with an eleven-year-old boy who responded characteristically
to simple questions such as "How are you today?" with "My God!
The world is coming to an end. The weasel stole all of the bees ... no more
honey ... no more money. The heck with you, you S.O.B. What do you have against
fried flies?"
A particularly
important instance of cognitive dysfunction is in the child's perception
of reality. During normal development we learn to move about
unimpaired in our environment by interpreting external cues. We learn that
distant objects look smaller than nearer ones and to correct our perception
when these cues are incorrect, such as when viewing things that are submerged
in water. With practice and success experiences, our confidence in these
perceptions of physical objects and space increases. From time to time we check
our impressions with those of others, especially when in doubt. Misperceptions
or hallucinations occur when a person sees, hears, or smells
something that is not present in the external world of reality. Hallucinatory
experiences may involve any of the senses, although visual and auditory
misperceptions are the most frequently noted. Beliefs that are based on false
premises are known as delusions, which are faulty perceptions
or incorrect appraisals of reality or the actual behavior of others.
The ramblings of a
five-year-old child about his or her imaginary playmate may be normal, but
similar behavior in a teenager would be properly labeled as abnormal. The
belief that the moon dangerously pollutes the atmosphere because it is made of
blue cheese is distinctly abnormal in a college graduate, although it may be
within normal limits for a gullible retardate who was spoofed by an older
sibling. Thus, in order to be useful as a criterion of abnormal behavior,
cognitive dysfunction must be considered in light of intellectual potential,
developmental norms, frequency, duration, and degree of impairment.
Emotional Expression and Control as a Criterion Some of the most vivid
illustrations of abnormal behavior come from the emotional area of human
functioning. Scenes of wild, explosive, and unpredictable emotional
expressions are often used to describe the behavior of those considered
abnormal. Extremes or sudden fluctuations of moods, infantile, inappropriate,
or lack of emotional expression, and irrational but persistent fears are some
of the emotional signs of personal instability. "A proper emotional
development prepares the individual to appreciate the pleasurable aspects of
emotion and to cope adaptively with the unpleasant. The well-rounded
personality is not flat or wholly intellectual but expressive and emotionally
responsive in a disciplined manner" (Nash, 1970, p. 306).
During the course of
development, children learn to alter the way they express emotions. Infants
show fear by crying, while teenagers may respond by avoiding or withdrawing
from the feared stimuli. Children also learn to size up the situation in terms
of what emotion is appropriate and what manner is acceptable for its
expression. With maturity, people are expected to increase the degree of
control they exercise over their feelings. Thus, over time youngsters may show
required changes in the expression of anger from frantic temper tantrums to
direct physical attack to verbal expression of anger, and so forth.
Deviations in
emotional expression and control are varied and numerous. Emotional behavior
can be inappropriate to the situation as in the show of
elation over the news of the death of a loved one, or insufficient or exaggerated as
reflected in either indifference or a prolonged grief reaction to a broken
engagement. There may be either too little or too much control exercised over
emotional responsivity as seen in impulsive acting-out behavior or in emotional
constriction and inhibition. In addition, emotional regression or the use of
emotional expressions evident in an earlier period of development may indicate
abnormal behavior. Temper tantrums in a twelve year old who had since learned
to express anger verbally is a sign of emotional regression and emotional
immaturity. Here again, the greater the deviation from normal developmental
patterns, the greater is the likelihood that the behavior would be regarded as
abnormal.
Sometimes personal
discomfort is considered a useful criterion of abnormal behavior,
because it is often (but not necessarily always) a byproduct of such a state.
Worry, anxiety, fears, and despondent feelings often become pervasive and
all-consuming to the point where some, if not many, areas of functioning are
affected adversely. When personal discomfort in any form is enduring and
sufficiently troublesome to interfere with normal functioning, it can be
considered abnormal. However, we must keep in mind that not all abnormal
emotional behaviors are painful or uncomfortable. Seriously regressed
psychotics may show silly emotional responses and a readiness to inflict pain
on others or themselves without any apparent sign of personal distress. Those
in prolonged states of euphoria (even if inappropriate) appear to be ecstatically
happy. Sexual deviants and drug users apparently derive a great deal of
pleasure from their abnormal behaviors.
Coping in Interpersonal Relations as a Criterion It is well recognized
that humans are not solitary creatures but social animals who require
relationships with others for their well being. To function adequately in
society, a person must acquire the capacity to interact with others on friendly
and cooperative terms and maintain relationships of mutual respect, agreement,
and responsibility. Because this is such an important area of human function,
deviations from the expected patterns, especially those in which the rights of
others are offended or violated, are considered abnormal. Typically,
disruptions in a person's ability to cope with interpersonal relationships are
associated with or lead to impaired functioning in many areas. Difficulties in
interpersonal relations, such as social withdrawal and isolation,
suspiciousness, fear, hatred of others, and uncooperativeness are behaviors
that make almost any facet of life difficult to manage.
But not all deviant
interpersonal relations justifiably fall within the domain of abnormal
behavior. Rudeness, insensitivity, deceit, and infidelity are among the behaviors
that are socially deviant, but not in and of themselves abnormal. Similarly,
criminal acts of murder, rape, and theft, while deviant, cannot be classed as
abnormal without further qualifications.
What then are the
necessary additional considerations? If the behavior is committed by a person
who is rational and otherwise shows no signs of cognitive impairment, then we think
of the act, albeit vulgar, immoral, or criminal, as outside the domain of
abnormality. If, however, the behavior is performed by a person whose judgment,
thinking, memory, or perception is disturbed, then we consider the behavior
abnormal. Emotional dysfunction is another factor that helps differentiate
abnormal social behaviors from other kinds of deviant interactions. When
emotional instability is present along with deviant interpersonal behavior,
the social interaction is more likely to be abnormal than criminal. Therefore,
in order to use interpersonal deviancy as a criterion of abnormal behavior, it
is necessary to apply it in conjunction with the other criteria of cognitive
and emotional dysfunction.
In summary, there is
no single criterion for defining abnormal behaviors. However, for our purposes,
we defineabnormal behaviors as those that persistently deviate
from cultural and developmental norms in either extremes of frequency and
intensity, and that are evidenced by impairment in one or more of the following
areas of human functioning: intellectual and cognitive, emotional expression
and control, and interpersonal relationships.
How Is Psychopathology Classified? In the field of
behavior disorders, a classification system arranges those individuals
exhibiting abnormal behavior into diagnostic groupings according to certain
common characteristics. From the very beginning, classification has been
influenced greatly by a disease view of psychopathological behavior. This
influence dates back to the contributions of Hippocrates, although the major
impetus came in the nineteenth century when Emil Kraepelin undertook the
careful compilation of clinical records and histories of hospitalized
patients. Based on these data, he constructed a classification system that was
essentially a descriptive one, in which all of his observations and clinical
findings were used as diagnostic criteria. The data included symptoms and
clusters of symptoms, etiology when known, physiological changes, and observations
about the course and outcome.
In addition to
Kraepelin, several others have contributed to present-day classification of
abnormal behavior. Eugen Bleuler (1857--1939), who worked extensively with the disorder
known as dementia praecox, or schizophrenia,
brought about significant changes both in the name and the concept of that
disorder. Bleuler's lucid description of schizophrenia and its subcategories
not only replaced the Kraepelinian view of the disorder but also significantly
modified its classification up to the present. Adolph Meyer (1866-1950) argued
against the Kraepelinian bias that focused on the study of symptomatology, and
especially against the inclination to view symptoms as signs of specific brain
lesions. He took a broader approach claiming that abnormal behaviors were faulty
life adaptations produced by many factors such as psychological,
social, physiological,and constitutional, and not exclusively brain pathology.
He introduced the concept of reaction types as
a substitute for the narrowly conceived disease entities, and he emphasized the
total individual as a psychobiological organism constantly called upon to adapt
to a social environment (Meyer, 1948; Muncie, 1948).
Because no single
system of classifying abnormal behavior had been adopted as the official
standard in the field, diversity tended to prevail. Clinicians either modified
existing systems or constructed their own to meet their special needs and those
of the clinical facilities in which they worked. The result was "a
polyglot of diagnostic labels and systems, effectively blocking communication
and the collection of medical statistics "Diagnostic and Statistical
Manual, 1965, p. V), This state of
confusion triggered off several attempts to establish a standard nomenclature
that would be nationally accepted and used.
Adult Classification Systems (DSM-I, DSM-II, DSM-III) In 1927, the New York
Academy of Medicine moved to establish a standard nomenclature of disease
that would be nationally accepted. The first edition entitled Standard
Classified Nomenclature of Disease was
published in 1933 and was followed by two revisions, the last of which appeared
in 1942. During World "Val' II, however, psychiatrists found this system
to be inadequate, since it dealt effectively with only ten percent of the
total cases seen. Following the war, the American Psychiatric Association
undertook a revision of the Standard system. Based on material received from
the Army and Veterans Administration, ideas from psychiatric training programs,
suggestions from their own members, and data from the literature, they drafted
a proposed revision. They revised it again and finally published it in 1951 as
the Diagnostic and Statistical Manual (DSM-I).
Curiously enough, the manual virtually ignored childhood disorders per se
except for the inclusion of a few conditions that it listed with adult
syndromes, in a manner somewhat reminiscent of the way children were viewed
before childhood was discovered. In 1968, a second revision was published,
known as DSM-II, which consisted of ten major categories. For the first time
one of these categories was devoted exclusively to children ("Behavior
Disorders of Childhood and Adolescence") and included the following
subcategories:
Behavior disorders,
hyperkinetic reaction, withdrawing reaction, overanxious reaction, runaway
reaction, unsocialized aggressive reaction, group delinquent reaction, and
other reaction. In addition, another major category, transient situational
disturbances, dealt with special symptoms most commonly found in children.
These additions, albeit far from adequate, represented a substantial shift in
the recognition given to child psychopathology by the American Psychiatric
Association.
DSM-III is the latest
and most radical revision not only in its attempt to be both specific and
inclusive but also in its rather extensive provisions for childhood
disorders [DSM-III: Diagnostic and Statistical Manual of Mental
Disorder(3rd ed.), 4-15-77 draft]. This classification system consists of
seventeen major categories summarized in Table 2-1. It also provides
operational criteria that specify the clinical phenomena needed to justify the
diagnosis, and a multiaxial framework that gives the diagnostician additional
categories on which to code the patient. There are five axes: two dealing with
other categories of mental disorders; one for designating nonmental medical
disorders; one for rating the severity of psychosocial stressors; and one
characterizing the highest level of adaptive functioning the patient achieved
within the last year.
The major category
devoted to child psychopathology is more extensive and inclusive than what
appeared in the previous two editions. It is designated as "Disorders
Usually Arising in Childhood or Adolescence". Psychosexual disorders,
particularly gender disturbances that occur during childhood and adolescence
are not included in this section, although they are covered in the adult part.
Surprisingly, this major category sets no age limit separating childhood from
adolescence, and, in fact, includes subcategories that may be appropriate for
the college years (Identity and Emancipation Disorder) or for older adults if
the present condition dates back to early childhood (Attention Deficit Disorder).
Childhood disorders resembling those seen in the adult but that may not lead to
their adult. counterpart are given separate subcategories in this section. In
addition, there are many diagnoses offered elsewhere in the manual such as
phobias and adjustment disorders that can be applied to children.
The final draft of
DSM-III, due to be published sometime in 1979 or 1980, is clearly more
comprehensive and explicit in diagnostic criteria and categories than the
previous editions. Although it is too early to judge, DSM-III gives every
indication of being significantly more reliable and valid than any
classification system that has yet to appear. In addition, DSM-III should
reassure those concerned with the tendency of classification systems to neglect
the "whole" individual. While the very nature of any sort of
classification is to highlight some features and ignore others, with its
multiaxial orientation, DSM-III minimizes this problem by looking at children
and adults from many perspectives.
Child Classification Systems Although the need for
a uniform classification system for children and adolescence had been noted
for years (Group for the Advancement of Psychiatry, 1957), it was not until
1966 that the Committee on Child Psychiatry of the Group for the Advancement
of Psychiatry (GAP) completed and published their proposed system (Group for
the Advancement of Psychiatry, 1966). At the time of publication, there were at
least twenty three other child classification systems in use, illustrating the
diversity and diagnostic confusion that has characterized the field.
The GAP system
consists of ten major categories ordered (although poorly) along the dimension
of prognosis, and ranging from healthy responses to the most severe disorders.
Embracing the psychosomatic, developmental, and psychosocial views, the
system can best be characterized as a clinical descriptive one that can be
used by clinicians of varying backgrounds. The category, Healthy Responses,
has never been used in any system but is included here to minimize the practice
of clinicians to exaggerate minor childhood problems into pathological ones for
classification purposes. For example, the new category gives the clinician the
opportunity to categorize bedwetting in a two-year old as a healthy response
rather than calling it abnormal. Another new category, Developmental
Deviations, deals with deviations in maturational rate, or sequence, or personality
development that are frequently noted in children but that are not adequately
classified under other systems.
In 1969, The World
Health Organization (WHO) published a multi axial classification system for
childhood disorders (Rutter et al., 1969). This system
includes the following four axes: (1) clinical psychiatric syndrome, (2)
intellectual level (IQ), (3) associated etiological biological factors, and
(4) any associated etiological psychosocial factors. Thus, a psychotic child
(1) who is severely retarded (2) and who has epilepsy (3) would be coded on
three of the four axes. The advantage of classifying children on various
relevant dimensions offered by the WHO system is now available in the new
multiaxiallook of DSM-III.
A statistical
technique, known as factor analysis, has
been used empirically to isolate clusters of characteristics observed in
children that then become the major categories of the classification system.
The effectiveness of this statistical approach rests on the nature and
character of the items on which each child is rated, since the final cluster of
symptoms is derived from these initial data. Consequently, factor analytic .
classifications differ from one investigator : another, because the original
variables under study and the items used to measure them are likely to be
divergent. An example of a factor analytic classification scheme is
the one proposed by Achenbach (1966), who found two general clusters
which he called internalizing and externalizing or personality
problems and conduct problems. In addition to
the general clusters, the system also includes specific symptom clusters that
are either subsumed by the general clusters or peculiar to certain
developmental periods. Some of the internalizing symptoms
include phobias, insomnia, stomach-aches, and seclusiveness, while externalizing symptoms
include destructive, stealing, and running away. These factorial data have been
replicated with new samples of children and have been used to show that externalizingboys
were independently rated as more impulsive and aggrressive, while internalizing boys
were considered more passive, more inclined to stay longer in psychotherapy,
and to improve with treatment (Achenbach and Lewis, 1971). Several other
studies using these two general clusters with children from clinics and schools
indicate relationships that support the validity of these categories
(Achenbach, 1974) .
The best known and
most widely used psychoanalytic approach to classification is Anna Freud's
"Developmental Profile" (Freud, 1965). Essentially, the profile is a
diagnostic tool based on the developmental sequence proposed by psychoanalytic
theory. It is used as a standard with which to compare the development of a
given child. Freud rejected the heavy reliance on symptom description as the
basis of diagnosing children's disorders and favored instead a more thorough
assessment of the child's personality structure, functioning, and development,
detailed in her developmental profile. However, she gave no objective criteria
to aid the clinician in completing each part of the profile or indications of
how information on the separate variables should be integrated and
synthesized. Unfortunately, the profile has spawned little research and even
less evaluative data, since the publications to date have, for the most part,
been clinically descriptive of a single case.
Other and more
specific classification schemes have been used for research purposes,
especially in instances where investigators are concerned with studying one or
relatively few psychopathological conditions. Usually these miniature systems specify
a set of diagnostic criteria that are more behavioral and more amenable to the
careful selection of clinical populations for study than is possible with the
more traditional and global systems. For example, the DeMyer-Churchill system
(DeMyer, Churchill, Pontius, and Gilkey, 1971) provides a set of criteria to
distinguish psychotic children (see Chapter 8) into subgroups that are not
included in DSM-III, GAP, or other systems previously described. Similarly, a
checklist prepared by Rimland (1971) to differentiate one group of psychotic
children from other groups (discussed in Chapter 8) is still popular with
researchers studying childhood psychoses.
Reliability of Classification From the time of
Kraepelin to the present, the classification of abnormal behavior has had as
its principal goals the understanding of etiology, the prediction of the
course and outcome, and the appropriate selection of treatment for the various
abnormal conditions. To a large extent, the usefulness of a classification
scheme depends on the degree of consistency or agreement achieved in
categorizing abnormal behavior. If little agreement is obtained, then the
system has very limited pragmatic value in meeting the purpose for which it was
constructed. The issue we raise is the important matter of reliability, which
we shall now consider.
The Reliability of Classification The reliability that
we speak of may be one of three types:
1. Observer
agreement-a measure of agreement of categorization
by two or more observers.
2. Consistency
agreement-a measure of agreement on categories over
time, such as between the initial and final diagnosis.
3. Frequency
agreement-a measure of agreement between two or
more random samples of the same population with regard to the frequency of
cases falling into each diagnostic category (Zubin, 1967).
Most studies of
reliability have been, in fact, concerned with observer agreement, and have
been based on the adult categories specified in DSM-I. We should also note
that the data obtained from many of these studies, especially the earlier ones,
are difficult to interpret because of their methodological shortcomings. These
shortcomings involve (1) very small and unrepresentative samples of patients,
(2) lack of control for rater differences in training and experience, and (3)
dearth of information about patients on which ratings were based (Beck, 1962).
More carefully designed studies have shown consistently that agreement is high
when the classification is restricted to a few major categories that are
grossly distinct from each other. However, reliability estimates sharply
decline when a greater number and more specific diagnostic categories are
included (Hunt, Witson, and Hunt, 1953; Schmidt and Fonda, 1956; Kreitman,
Sainsbury, Morrisey, Towers, and Scrivener, 1961; Sandifer, Pettus, and Quade,
1964).
In general, consistency
of diagnosis over time as a reliability measure yields even lower
estimates than that obtained from studies of observer agreement (Zubin, 1967).
However, this finding may be more indicative of the dramatic changes that can
take place in the symptoms of a patient from one period of time to another than
of poor
rater
reliability. This is particularly true of those patients who, after a brief
period of hospitalization, show a decrease in agitated and anxiety generated
behavior because they are now in a more secure and protected environment. In
addition, the increased use of drugs to treat patients and to make them more
manageable has tended to bring about symptom changes over time.
Illustrative of the
third measure of reliability, frequency agreement, is
a study involving 538 women who were admitted to a large midwestern psychiatric
hospital for the first time (Pasamanick, Dinitz, and Lefton, 1959). The
patients were assigned to one of three autonomously operated wards on the basis
of bed availability. There were no differences among the patients on the three
wards with respect to marital status, age, education, urban-rural residence, or
type of admission (voluntary or involuntary). Three different psychiatrists
were placed in charge of each ward. In this way, a situation was constructed
that provided each psychiatrist with equal access to patient information from
other professional workers and with the "same type" of patient to
diagnose. The results showed marked discrepancies among the samples with
respect to the frequency that the three major diagnostic categories were used.
In this connection, Zubin noted that of four studies he reviewed (including
Pasamanick et al.), only
one showed agreement among samples. He
concluded, "In general, the results of comparative studies of random
samples with regard to distribution of diagnoses do not yield a
consistent picture regarding reliability" (Zubin, 1967, p. 388).
Interest in assessing
the reliability of the classification of children's disorders is recent,
primarily because there was no single systern that could be used uniformly
until the appearance of the GAP proposal. Since its publication, the GAP scheme
has been the subject of several investigations. One study found that two of the
GAP categories accounted for seventy five percent of the 200 cases sampled
(Personality Disorder and Psychotic Disorder). Six other categories were used
sparingly (from about four to eight percent), while the two new categories
(Healthy Responses and Developmental Deviation) practically were not used at
all (Sabot, Peck, and Raskin, 1969). Another study attempted to determine the
effectiveness of the GAP system over a twelve month period (Bemporad,
Pfeiffer, and Bloom, 1970). In contrast, the new categories were found to be
useful for this sample of 310 children in that they accounted for almost twenty
four percent of the cases. Moreover, the distribution of the cases among the
GAP categories between these two studies differed markedly in almost all
instances. It is difficult to resolve the large discrepancies between these
two studies, because the second study did not describe the patients Hsed with
respect to socioeconomic level, race, age, educational level, and family
structure. It is entirely possible that some of the differences in the findings
were attributable to the substantial differences in the population sampled.
The most extensive
study to date involved the diagnosis by twenty experienced child psychiatrists
of forty four cases (case histories and diagnoses) submitted by member of the
GAP subcommittee (Freeman, 1971). The results indicated that four categories
(Reactive Disorders, Neurotic Disorders, Personality Disorders, and Psychotic
Disorders) accounted for eighty three percent of the diagnoses, while the
remaining categories accounted for only seventeen percent of the diagnoses.
The two new categories (Healthy Responses and Developmental Deviation) were
rarely used, once again raising the question of their value in a classification
system. The reliability of the four frequently used categories was between
sixty one and seventy two percent. There was no evidence that diagnostic agreement
is higher for any specific age group. Data were also gathered to obtain a
consistency over time measure of reliability by requiring the twenty clinicians
to rediagnose a sample of selected cases some three months later. The
clinicians placed eighty six out of a total of 120 diagnoses in the same
category as before, yielding a seventy two percent agreement estimate. This
figure is even more impressive in light of the fact that three cases accounted
for twenty six of the thirty four disagreements recorded, and that three cases
were responsible for low agreement even in the initial ratings. These findings
reflect fairly high reliability for the four categories used most frequently,
and a decrease in reliability when more specific subcategories are employed.
No data are available
as yet with which to evaluate the reliability of the other classification
systems discussed earlier.
Evaluation of Classification Evidently the
reliability of psychiatric classification is low except when diagnosis is restricted
to a few broad categories. Although much of this evidence comes from studies
using an out-dated system primarily intended for adults, similar inferences
seem to be supported by data involving children and a classification scheme for
child psychopathology (GAP). Diagnostic accuracy becomes increasingly more
difficult as more categories are used and finer discriminations are required.
The validity question, that is, how well diagnosis meets its goals, is
extremely difficult to answer, since the goals of classification are so
numerous and diverse.
In addition, DSM-II
has been seriously criticized on other grounds. It has been regarded as
unscientific in that it was finalized by a majority vote of selected
psychiatrists rather than firmly rooted in careful empirical study. Perhaps
more damaging is the confounding of etiology, symptoms, and outcome as the
bases for diagnosis. Commenting on this diversity of principles, Draguns and
Phillips stated, "This confusion not only makes for conceptual inelegance;
it implies an ever continuing process of diagnosis terminated only at the point
of patient's death. Ultimately, this orientation makes diagnosis intrinsically
uncertain and unknowable" (Draguns and Phillips, 1971, p. 5). The use of
behavioral description as the basic data for classification has been suggested
as an alternative (Zigler and Phillips, 1961). Both etiology and prognosis
would be treated as correlates of the particular class to which their relationship
is known, but not as inherent attributes of the various categories. It can be
argued that the present classification system is even inadequate as a
descriptive scheme, because the principle of symptom appearance is not applied
consistently to all categories, and the symptoms presumed to be associated
with each category are not clearly specified. The system simply fails to delineate
the criteria for making assignments to any given category.
Another major
criticism is that classification implies separate and mutually exclusive
entities. Yet there is considerable overlapping in symptomatology among the
categories. For example, it has been found that the symptom of depression
occurrence in sixty-five percent of patients diagnosed as manic-depressive, in
fifty-eight percent of those diagnosed as psychoneurotic, and in thirty—one
percent of those diagnosed as character disorders (Zigler and Phillips,
1961). Moreover, in actual practice, only one or two symptoms may be used
to determine the diagnosis, although a particular entity often is characterized
by many symptoms. The weight given to one or several symptoms for inclusion or
exclusion in a diagnostic category is, in fact, left to the judgment of the
clinician (Lorr, Klett, and McNair, 1963). It has been estimated that about
five percent of the disagreement in diagnosis is attributable to the
inconsistent behavior :he patient, 32.5 percent to the inconsistent
behavior of the diagnostician, and 62.5 percent to the inadequacy of the classification
system (Ward et al.,1962). If
this appraisal is correct, then diagnostic reliability can be increased to some
extent by reducing those disagreements introduced by the clinician. Improvement
in the clinicians' training in the uniform use of the classification scheme as
the basis for diagnostic decisions would go a long way in minimizing his
source of error. However, the problems inherent in classification strongly
suggest that primary attention must be directed to the development of changes
in the system itself.
The issue of attaching
psychiatric labels children has aroused controversy between those who see
potential danger in it, and those who see its advantage in early intervention.
Diagnostic labels, especially ones that reflect serious disorders, may stick to
the child over the years and possibly influence later evaluations even when
they are no longer appropriate. Labeling may stigmatize and set the child apart
from peers, and it may encourage others to look for the child to behave in a
way commensurate with. the label. Unfortunately, diagnostic categories appear
real and valid to many, although we now know that they lack the
precision and reliability to warrant such confidence. For these reasons and to
protect children from future abuses, many clinicians are reluctant to fix a
diagnostic label to children who evidence abnormal behaviors, if in the future
there is a chance that others might have access to the diagnosis. On the other
hand, it can be argued that diagnostic labels need not be abused or
misinterpreted if the clinician exercises care in the evaluation and good
judgment about who has access to it. The diagnosis should serve as the basis of
a treatment plan and should be helpful in later evaluations of the child as a
basis for comparison and as a measure of the child's progress.
For the present,
DSM-III and to a lesser extent the GAP proposal enjoy official status and
widespread use throughout the country. Within the limitations already noted,
classification brings uniformity to the ordering of psychopathology and
continues to serve an important communication function among professionals.
While it is necessary to be aware of its shortcomings, it would be premature
to ignore or completely reject the current system. Meehl supported this
position when he remarked, "There is a sufficient amount of etiological
and prognostic homogeneity among patients belonging to a given diagnostic
group, so that the assignment of a patient to his group has probability
implications which it is clinically unsound to ignore" (Meehl,
1959, p. 103). More recently, it has been argued that
classification is essential for research and fundamental to the clinician in
organizing the multi-faceted aspects of mental disorders
(Shakow, 1968). Over the years, classification has increased our
knowledge of psychopathology, and further important insights should be
forthcoming with increased efforts to improve both the system and the process.
We are drawn to the conclusion that the student must be familiar with the
diagnostic categories presently used, because they represent handles that
systematically open the storehouse of available knowledge in the field. In addition,
they stress the orderly and careful accumulation of observations so necessary
for making diagnostic decisions.
Scope and Measurement of Psychopathology Measures
Statistical data about
the occurrence of abnormal behavior may be arrived at in three different ways:
incidence, prevalence, and expectancy. Incidence refers to the
total number of new cases of a disorder that occurs within a
specified population and a period of time. Prevalence is a
more extensive measure in that it refers to the total number of cases (old and
new) present in a given population during a specified time interval.
The major difference
between incidence and prevalence measures is that the latter reflects both
incidence and duration. For example, if we interpret as incidence data the
often cited statistic that over one-half of all hospital beds are occupied by
the mentally ill, we would conclude erroneously that there are more people who
evidence abnormal behavior than is actually the case. However, if we understand
this finding as prevalence data, we recognize the fact that the internment for
mental disorders is much longer than the time required for other hospitalized
conditions. Therefore, the statistic should not be taken to mean that one-half
of all new hospital admissions each year consists of mentally ill people, but
rather that mental patients occupy half of the beds available because their
hospital stay is relatively long (Kramer, 1957; Malzberg, 1963).
The probability that a
person will fall into a specific category of abnormal behavior sometime during
his or her lifetime is an expectancy measure. Although informative,
an expectancy measure is biased since it does not take into account the individual's
age when the question is asked concerning the chances of becoming mentally
ill. The longer one lives, the greater number of years available in which the
probabilities of abnormal behavior apply. Therefore, it is more useful to ask
what is one's risk of a behavior disorder if one lives to a
certain age. In this way, the risk is expressed as a conditional probability,
not as a joint probability of both living to such an age and becoming mentally
ill. For example, the probability of living to the age of ninety and being
mentally ill is less than the chances of having a behavior disorder given that
one does live to the age of ninety.
Sources of Error in Measurement Unfortunately, all of
these measures are subject to several sources of error that make it difficult
to estimate the extent of the problem in any definitive way. Typically,
frequency figures of abnormal behavior come from public and private clinics and
hospital census records. These data do not include instances of abnormal
behaviors that are tolerated or go unrecognized within some subcultures of our
society. For example, school phobias (fear of and refusal to go to school) are
more likely to go unnoticed in a low socio-economic urban area than in an
upper-middle-class urban neighborhood because truancy is implicitly sanctioned
in that subculture. In addition, the measures do not reflect the number of less
severe cases
that are handled within the confines of the family, or those cases that are
masked by physical symptoms such asthma. There is a strong tendency for some
parents to postpone as long as possible the professional attention needed by
their disturbed children. For that matter; some professionals tend to shy away
from using "diagnostic labels connoting severe abnormal conditions to
reduce the danger that the diagnosis will adversely affect how others react to
the child in the future. Moreover official statistics are not adjusted in terms
of the availability of services and facilities. Therefore, they do
not include those cases that are unadmitted because facilities either are
nonexistent or unavailable because of overcrowded conditions. A more serious
source of error is the great diversity among professionals and institutions
with regard to the definition and classification of abnormal behavior.
Therefore, all of these measures are affected in an unsystematic way by the
variability of the diagnostic labels used to categorize abnormal behaviors.
Scope of the Problem Despite of these
limitations, we do know that the United States faces a sizable and serious
problem. The 1970 census indicated : "\\'e are a nation of young
people with approximately fifty million of our citizens classified as minors
(twenty six percent of the total population) and with one-half of
this figure under the age of ten. Several separate estimates give cause for
concern in that they reflect that up to ten percent of all school
age children require professional attention for abnormal behaviors, and that
children now constitute about thirty four percent of the total population
served by outpatient mental-health centers as compared to twenty-seven percent
in 1967 (Bower, 1969; Crisis
in Child Mental Health: Challenge for the 1970's, 1970; Garmezy,
1975). Since 1973, the number and rate of hospital admissions
(adjusted for birth rate) among children under eighteen years of age has been
declining. However, it is too early to tell if this is a reliable trend or
nothing more than yearly fluctuations like those noted in the previous four
years (Taube and Meyer, 1975). In all probability, the decrease in
hospital admissions represents a significant shift away from mental hospitals
to a more extensive use of relatively new community facilities such as
community mental-health centers. Of the children under eighteen years of age
admitted to state and county mental hospitals in 1973, one percent
was under five years of age, seven percent were between five and nine years,
thirty percent were between ten and fifteen years, and sixty three percent were
between fifteen and seventeen years old. However, the age at which children
most frequently are referred for professional attention is between ten and
fourteen years (Redick, 1973).
It has been known for
a long time that boys outnumber girls in practically every diagnostic category
of abnormal behavior, although as yet no satisfactory explanation for this
finding is available. In some instances, the male-female ratio is as high as
5:1 (Gilbert, 1957; Morse, Cutler, and
Fink, 1964; Redick, 1973). Equally puzzling is the fact
that this relationship tends to hold until late adolescence. However, it dissipates
in adulthood to the point where females may even exceed males in those abnormal
conditions where unequal sex distributions are found. For hospitalized children,
the boys exceed girls in every age group, but especially between the ages of
five and nine years (Taube & Meyer, 1975).
Although the magnitude
of aberrant behaviors in children is greater than we would wish, we can look
to the future with optimism knowing that the field now provides formal
training for its professional workers. Moreover, the encouraging advances in
knowledge obtained through research make it more reasonable than ever before to
expect that abnormal behaviors of children will be identified earlier, treated
more effectively, and, to a greater extent, prevented.
Summary Abnormal behavior was
defines in terms of the following criteria:
1. Cultural
Norm: the established standards and expectations approved by the culture for
the behavior of its members.
2. Developmental
Norm: The expectations based on our knowledge of the developmental process.
3. Intellectual
and Cognitive Functioning: an apparent disparity between ability and actual
performance in attention, comprehension, judgment, learning, memory, thinking,
and perception.
4. Emotional
Expression and Control: an insufficient or an exaggerated emotional reaction,
inappropriate emotional expression, infantile emotional reactions, moods of
despondency, extreme elation, sudden fluctuation, or too little or too much emotional
control.
5. Coping
in Interpersonal Relations: disruptions in or inability to cope with interpersonal
relations, social withdrawal, isolation, suspiciousness, fear and hatred of
others, and uncooperativeness. This criterion must be used in conjunction with
the other criteria of cognitive and emotional dysfunction.
We also argued that
the characteristics of frequency, intensity or degree, and duration are
necessary in applying the above criteria in defining the domain of abnormal
behavior.
We presented summaries
of the new psychiatric classification system (DSM-III) and the GAP proposal
for the classification of children's disorders. In addition, we considered the
WHO multiaxial classification for childhood disorders, Achenbach's factor
analytic system, Anna Freud's developmental profile, and other miniature
schemes for research purposes.
We discussed measures
of reliability and research findings. In general, reliability of classification
is fairly high when few and broad categories are used, but it declines sharply
when a greater number and more specific categories are included. We reviewed major
criticisms and problems inherent in the classification system, although we concluded
that classification brings order and uniformity to psychopathology and serves
an important communication function among professionals.
We also considered the
problems associated with estimating the frequency of occurrence of abnormal
behavior, and we defined incidence, prevalence, and expectancy measures. All
of these measures are affected by the variability of the diagnostic labels used
to categorize abnormal behavior, by the availability of service facilities, by
instances that are either tolerated or unrecognized within some subcultures
of our society, and by the inclination of families to deny or ignore the
problem. We presented some overall estimates of the scope of the problem.
Epilogue The follow-up story on
Martin is disappointing. During the three years he was seen at the Clinic,
Martin had several different therapists in both individual and group
psychotherapy. An abnormal EEG was uncovered, which together with his acting
out behavior suggested potential benefit from chemotherapy. He was given two
anticonvulsant drugs for almost a year and a half, although no behavioral
improvements were noted. Soon thereafter, Martin was placed on a trial dose of
an amphetamine which, according to the therapist, produced positive
behavioral results. However, his mother and teachers observed no improvement in
his behavior. Finally, medication and psychotherapy were discontinued because
the family became pessimistic over Martin's prospect for improvement and the
clinic's effectiveness in treating' him. Possibly the absence of a careful
diagnostic work-up and the failure to arrive at a diagnosis for Martin were
significant factors in the clinic's ineffectiveness in structuring an
appropriate treatment plan for Martin and his family.

TABLE 2-2 Summary Description of DSM-Its Category on Childhood Disorders Disorders Usually
Arising in Childhood or Adolescence
The disorders in this
section usually arise and are evident in childhood or adolescence, although no
arbitrary age limit is used to define childhood or adolescence. The diagnoses
in this section may apply to adults if they experienced the condition since
childhood and no adult category applies. Childhood conditions resembling adult
disorders that may not be continuous with these adult conditions have been
given different names. A severity rating of functional impairment is made for
conduct disorders. The multiaxial framework should be used whenever possible.
1. Mental Retardation
Three essential
features must be present: (1) significant subaverage general intellectual
functioning, (2) concurrent deficits in adaptive behavior, and (3) onset before
the age of eighteen. The diagnosis is made regardless of the nature of the
etiological factors, although a known biological cause should be coded on Axis
III. When mental retardation develops after age eighteen, it is designated as a
dementia and is coded within the organic mental disorders section. There are
four subtypes of mental retardation reflecting the degree of intellectual
impairment. These are labeled as mild, moderate, severe, or profound depending
on an IQ criterion.
2. Pervasive
Developmental Disorders
These disorders are
characterized by distortions in the timing, rate, and sequence of many basic
psychological functions, and they differ from specific developmental disorders
in two ways: (1) the specifics show a delay in time or rate of specific
discrete functions while the pervasives evidence a marked distortion of the
timing, rate, and sequence of many general psychological functions that
profoundly distort social and interpersonal development; and (2) the specifics
appear as if they are passing through an earlier normal developmental stage,
while the pervasives manifest severe qualitative abnormalities that are not
normal for any stage of development. Pervasive development disorders were previously
labeled atypical children, symbiotic psychotic children, and childhood
schizophrenia.
A. Infantile
Autism
The essential features
of this syndrome include lack of responsiveness to other human beings, gross
impairment in communicative skills, and bizarre responses to various aspects of
the environment. All features develop within the first forty-two months of age.
The operational criteria of infantile autism are as follows: (1) onset usually
prior to thirty months but up to forty-two months, (2) lack of responsiveness
to other human beings, (3) self-isolation, (4) gross deficits in language
development, (5) if speech is present, peculiar speech patterns, and (6)
peculiar interest or attachments to animate or inanimate objects.
B. Early
Childhood Psychosis
Profound disturbance
in emotional relationships with people and a multiplicity of bizarre characteristics
developing during infancy or early childhood are the essential features. Early
childhood psychosis is diagnosed by the following operational criteria: (1)
gross and sustained impaired emotional relationships, (2) bizarre beliefs or
preoccupations, (3) four of the eight associated features (acute and illogical
anxiety, disturbed affect, resistance to environmental change, peculiar
motility, speech abnormalities, language disturbances, abnormal sensory and
perceptual experiences, self-mutilation), and (4) onset during infancy or
early childhood.
C. Pervasive
Development Disorder of Childhood, Residual State
This category is
intended to meet the following operational criteria: (1) the patient's
condition once was diagnosed as a pervasive developmental disorder, (2) the
current clinical picture does not meet the criteria for either infantile autism
or early childhood psychosis, and (3) the patient is still manifesting symptoms
caused by the original disorder.
D. Unspecified
Pervasive Developmental Disorders 3. Attention Deficit Disorders
This category includes
two separate disorders characterized by developmentally inappropriate short
attention and poor concentration.
A. Attention
Deficit Disorder with Hyperactivity
The operational
criteria for this disorder are as follows: (1) excessive general hyperactivity
or motor restlessness for age, (2) difficulty sustaining attention, (3)
impulsive behavior as evidenced in at least two of the following: sloppy work
but with effort to perform, frequent calling out of turn or making
inappropriate sounds in class, frequent interruption .of or intrusion into
activities of other children, difficulty waiting for one's turn, poor frustration
tolerance, fighting with children brought on by low frustration tolerance, and
(4) duration of condition at least one year.
B. Attention
Deficit Disorder Without Hyperactivity
Children with this
disorder manifest, for their age, an impairment in the ability to concentrate,
difficulty in completing tasks, and conspicuous lack of organization or forethought
as they move from one activity to another. They exhibit difficulty sustaining
attention and focusing attention but without hyperactivity. The diagnosis
should not be made before the age of four. Specific developmental disorders are
common and should be coded on Axis II. Impaired academic performance often is
present. The operational criteria for this disorder is similar to those
described in (A) except for the hyperactivity and motor component.
4. Specific Developmental
Disorders (Axis II)
These disorders are
coded on Axis II and are diagnosed only when there is a delay in development
that is notan essential criterion for another disorder. The coding
carries no etiological implications and should be made on the basis of the
individual's current level of functioning without regard to its origin.
A. Specific
Reading Disorder
The essential feature
of this disorder is a serious impairment in the development of reading skills
not explicable in terms of mental age or inadequate schooling. The impairment
should be determined by a performance on a standardized reading test and it
should be significantly less than predicted on the basis of the child's
chronological age and a fullscale IQ obtained from an individually administered
intelligence test.
B. Specific
Arithmetical Disorder
The essential feature
of this disorder is a serious impairment of arithmetic skills not explicable in
terms of mental age or inadequate schooling. The diagnosis should be established
by performance on standardized tests of arithmetic achievement significantly
below that which would be expected on the basis of the child's chronological
age and full-scale IQ on an individually administered intelligence test.
C. Developmental
Language Disorder
Delayed language
disorder is separated into two types:
1. Expressive
type is characterized by an impairment in the
encoding or production of language while the understanding or decoding skills
remain relatively intact. The operational criteria include a defect or delay
in. the production of language, and the absence of hearing impairment, general
retardation, trauma, or seizures that could explain the defect.
2. Receptive
type involves both the comprehension and
production of language such that language acquisition is severely impaired. The
deficit must be present from the first year of life and there must be an
absence of general mental retardation or other more pervasive disorder that
could explain the language disability in order for the diagnosis to be made.
D. Developmental
Articulation Disorder
The essential feature
9f this disorder is defective articulation of the later acquired speech sounds
occurring in the absence of other language impairment or physical or intellectual
disorders.
E. Coordination
Disorder
This involves a
serious impairment absence of mental retardation or any motor coordination
problems.
F. Enuresis
Primary Enuresis is
characterized by persistent involuntary voiding of urine by day or night that
is considered abnormal for the age of individual. The frequency should be at
least one such event per month after the child has reached the age of five.
Secondary
Enuresis is differentiated from primary by the
second operational criteria that states that the frequency should be at least
one such event per month after a period of urinary continence lasting at least
one year.
in the development of
motor coordination in the neurological disorder that would account for the
G. Encopresis
This disorder consists
of a persistent voluntary or involuntary passage of feces of normal or near
normal consistency in places deemed inappropriate for that purpose by the individual's
own sociocultural setting. This should occur at a frequency of at least one
such event per month for a period after the child has reached the age of five.
H. Mixed
Specific Developmental Disorders
This category should
be used when the patient manifests more than one specific developmental
disorder, none of which is predominant.
I. Other
Specific Developmental Disorders
This category is used
when there is a serious impairment in a specific area of development that is
not covered by the categories specified.
J. Unspecified
Specific Developmental Disorders
5. Stereotyped
Movement Disorders A. Motor
Tic Disorder
This disorder involves
purposeless, involuntary movements that are frequent, rapid, spasmodic and
repetitive, and that occur in the absence of an established neurological
etiology. The disorder's duration should be for at least one month, and no
verbal tics are present for the diagnosis to be made.
B. Motor-Verbal
Tic Disorder (Gilles de la Tourette Syndrome)
Individuals with this
disorder suffer from motor and verbal tics and from sudden vocalizations.
Other operational criteria include age of onset between two and fifteen years, multiple
involuntary motor and verbal tics, and symptoms that wax and wane.
C. Unspecified
Tic Disorder
D. Other
Stereotyped Movement Disorders
This category is
intended for conditions such as head banging, rocking, repetitive hand
movements consisting of quick rhythmical small hand rotations, or repetitive
voluntary movements involving the fingers or arms. They are distinguishable
from tics in that they consist of voluntary movements and are not spasmodic.
Children with these disorders are not distressed by the same symptoms as those
with tics.
6. Speech
Disorders Not Elsewhere Classified A. Stuttering
This disorder consists
of persistent repetitions or prolongations of sounds, syllables, or words; or
persistent, unusual hesitations and pauses that disrupt the rhythmic flow of
speech. It occurs in the absence of mental retardation as the cause of the
speech impairment.
B. Elective
Mutism
This disorder is
characterized by a pervasive and persistent refusal to speak in social or
school situations, though the children are able and willing to speak to
selected persons, usually family or peers. The diagnosis is made only when the
refusal to speak is not
The Nature of
Psychopathology
symptomatic of any
other disorder listed and when there is evidence of normal intellectual
functions.
7. Conduct Disorders
These disorders
involve repetitive and persistent patterns of misconduct such as delinquency,
destructiveness, or other violations of the rights of others beyond the
ordinary mischief and pranks of children and adolescents.
A. Undersocialized
Conduct Disorder. Aggressive Type
The operational
criteria include (1) a persistent lack of concern for the feelings of others;
(2) a pattern of antisocial behavior of at least four months' duration with at
least one of the following: assault, defiance and defiant disobedience,
destructiveness, cruelty, and vindictiveness; (3) failure to develop peer
friendship patterns; and (4) behavioral difficulties at school.
B. Undersocialized
Conduct Disorder. Unaggressive Type
These children (1)
fail to form social bonds and develop a pattern of normal attachment to others;
(2) lack bold or openly aggressive behavior, unless with those who are younger
and weaker than they; (3) show five or more of the following behaviors for at least
four months: stealing, lying, lack of friends, superficial friendliness for
self-seeking purposes, whining and temper tantrums, repetitive running away
from home overnight, repetitive staying out late at night, chronic
disobedience, complaining that "nobody likes me or nobody cares about
me," and poor frustration tolerance.
C. Socialized
Conduct Disorder
This disorder is
defined operationally by the following criteria: (1) involvement over at least
a four months' period in a pattern of antisocial behavior involving either
group fighting, petty thievery, minor vandalism, or other more serious
delinquent or antisocial activity, such as group stealing, burglary, larceny,
or assault, (2) evidence of some dependable and lasting attachments and
age-appropriate relationships with some persons, whether companions, family
members, or others, and (3) the presence of impairment in social relationships
in the family and in school, as well as impairment in age-appropriate
responsibilities at home and school.
8. Eating
Disorders
A. Anorexia
Nervosa
The essential features
of this disorder are excessive behaviors directed toward losing weight,
peculiar patterns of handling food, weight loss, intense fear of gaining
weight, disturbance about body image, and in women, amenorrhea.
B. Bulimia
This disorder is
characterized by an episodic pattern of binge eating (rapid consumption of a
large amount of food in a discrete period of time, usually less than two
hours), accompanied by an awareness of the disordered eating pattern and a
fear of not being abJe to voluntarily stop eating, and depressive moods and
self-deprecating thoughts. Bulimic patients must have at least three of the
following symptoms: rapid consumption of food during a binge; consumption of
high caloric food during a binge; inconspicuous eating during a binge; the
termination of binge eating by abdominal pain, sleep, social interruption, or
self-induced vomiting; repeated attempts to lose weight by severely restrictive
diets or self-induced vomiting; an eating pattern of alternate binges and
fasts; and use of cathartics for weight control.
C. Pica
This disorder involves
the persistent eating of non-nutritional substances for at least one month.
D. Ruminati (Merycism)
The essential features
are regurgitation of food with failure to thrive, or weight loss developing
after a period of normal functioning.
9. Anxiety
Disorders of Childhood
or Adolescence A. Separation
Anxiety Disorder
TiJe Nature of
Psychopathology
Exaggerated distress
of at least one month duration at separation from parents, home, or other
familial surroundings that is not accounted for by any other mental disorder.
B. Shyness
Disorder
This disorder involves
the persistent shrinking from familiarity or contact with all strangers to the
extent that it interferes with peer functioning. The child must be at least two
and a half years of age and the shyness must be present for at least three
months. These children usually have warm and satisfying relations with family
members.
C. Overanxious
Disorder
This disorder is
characterized by anxiety for at least three months evidenced by persistent
worrying about future events but not focused on a specific situation or object
and not attributable to a recent psychosocial stressor. The anxiety is not
symptomatic of another disorder and at least one of the following symptoms of
anxiety also must be present: concern with competence, difficulty falling
asleep, somatic complaints with no medical basis, and frequent frightening
dreams.
10. Disorders
Characteristic of Late Adolescence
A. Emancipation
Disorder of Adolescence or Early Adult Life
The essential feature
is symptomatic expression of a conflict over independence following the recent
growth of independence from parental control or supervision. The condition is
not secondary to any other mental disorder, and it must be manifested by two or
more of the following symptoms: difficulty making independent decisions,
increased dependence on parental advice, unwarranted concern about parental
possessiveness, adoption of values deliberately in opposition to parents, rapid
development of markedly dependent peer relationships, and homesickness.
B. Identity
Disorder
Distress over an
inability to reconcile aspects of the self into a relatively coherent and
acceptable sense of self, not secondary to another mental disorder with onset
not prior to an age of fourteen.
C. Specific
Academic or Work
Inhibition
The predominant
clinical feature is severe distress interfering significantly with any of the
following academic or work tasks and manifested by anxiety related to
examinations or other tests; inability to write papers or prepare reports or to
perform in studio arts activities, or by difficulty in concentration on studies
or work, or avoidance of studying or work which does not seem to be under the
conscious control of the individual. The previous academic or work functioning
should have been at least adequate, and the individual should have intellectual
and academic or work skills that are adequate, and the condition is not caused
by any other mental disorder.
11. Other
Disorders of Childhood or
Adolescence A. Oppositional Disorder
Pervasive opposition
to all authority regardless of self-interest occurring after the age of two
through the age of eighteen. There is a continual argumentativeness and an unwillingness
to respond to reasonable persuasion, which is not accounted for by a conduct
disorder, an adjustment disorder, or a pervasive developmental disorder.
B. Academic
Underachievement Disorder
Failure to achieve in
most school tasks despite adequate intellectual capacity, a supportive and
encouraging social environment, and apparent effort. The failure occurs in the
absence of a demonstrable specific learning disability and is caused by
emotional conflict not clearly associated with any other mental disorder.

TABLE 2-3 Psychopathological
Disorders in Childhood Proposed Classification
Healthy Responses
This category assesses
the positive strengths of the child and tries to avoid the diagnosis of
healthy states by the exclusion of pathology. The criteria for assessment are
the intellectual, social, emotional, personal, adaptive, and psychosocial
functioning of the child in relation to developmental and situational crises.
Healthy responses:
1. Developmental
crisis
2. Situational
crisis
3. Other
responses
2. Reactive Disorders
This category is based
on disorders in which behavior and/or symptoms are the result of situational
factors. These disturbances must be of a pathological degree so as to distinguish
them from the healthy responses to a situational crisis.
3. Developmental
Disorders
These are disorders in
personality development that may be beyond the range of normal variation in
that they occur at a time, in a sequence, or in a degree not expected for a
given age level or stage in development.
Developmental
Deviations:
1. Deviations
in maturational patterns
2. Deviations
in specific dimensions of development
3. Motor
4. Sensory
5. Speech
6. Cognitive
functions
7. Social
development
8. Psychosexual
9. Affective
10. Integrative
11. Other
developmental deviation
4. Psychoneurotic
Disorders
These disorders are
based on unconscious conflicts over the handling of sexual and aggressive
impulses that remain active and unresolved, though removed from awareness of the
mechanism of repression. Marked personality disorganization or decompensation
or the gross disturbance of reality testing is not seen. Because of their
internalized character these disorders tend toward chronicity, with a
self-perpetuating or repetitive nature. Subcategories are based on specific
syndromes.
Psychoneurotic
Disorders:
1. Anxiety
type
2. Phobic
type
3. Conversion
type
4. Dissociative
type
5. Obsessive-compulsive
type
6. Depressive
type
7. Other
psychoneurotic disorder
Personality Disorders
These disorders are
characterized by chronic or fixed pathological trends, representing traits that
have become ingrained in the personality structure. In most but not all such
disorders, these trends or traits are not perceived by the child as a source
of intrapsychic distress or anxiety. In making this classification, the total
personality picture must be considered and not just the presence of a single
behavior or symptom.
Personality Disorders
1. Compulsive
personality
2. Hysterical
3. Anxious
4. Overly
dependent
5. Oppositional
6. Overly
inhibited
7. Overly
independent
8. Isolated
9. Mistrustful
Tension-discharge disorders:
1. Impulse-ridden
personality
2. Neurotic personality
disorder Sociosyntonic personality disorders:
1. Sexual
deviation
2. Other personality
disorder
6. Psychotic Disorder
These disorders are
characterized by marked, pervasive deviations from the behavior that is
expected for the child's age. They are revealed in severe and continued
impairment of emotional relationships with persons; loss of speech or failure
in its development; disturbances in sensory perception; bizarre or stereotyped
behavior and motility patterns; marked resistance to change in environment or
routine; outbursts of intense and unpredictable panic; absence of a sense of
personal identity; and blunted, uneven, or fragmented intellectual development.
Major categories are based on the developmental period with subcategories in
each period for the listing of a specific syndrome, if known.
Psychotic Disorders:
1. Psychoses
of infancy and early childhood
a. Early
infantile autism
b. Interactional
psychotic disorder
c. Other psychosis of
infancy and early childhood
2. Psychoses
of later childhood
a. Schizophreniform
psychotic disorder b. Other psychosis of later childhood
3. Psychoses
of adolescence
a. Acute
confusional state
b. Schizophrenic
disorder, adult type c. Other psychosis of adolescence
7. Psychophysiologic
Disorders
These disorders are
characterized by a significant interaction between somatic and psychological
components. They may be precipitated and perpetuated by psychological or social
stimuli of stressful nature. These disorders ordinarily involve those organ
systems innervated by the autonomic nervous system.
Psychophysiologic
Disorders:
1. Skin
2. Musculoskeletal
3. Respiratory
4. Cardiovascular
5. Hemic
and lymphatic
6. Gastrointestinal
7. Genitourinary
8. Endocrine
9. Of
nervous system
10. Of
organs of special sense
11. Other
psychophysiologic disorders
8. Brain Syndromes
These disorders are
characterized by impairment of orientation, judgment, discrimination, learning,
memory, and other cognitive functions, as well as by frequent labile affect.
They are basically caused by diffuse impairment of brain tissue function.
Personality disturbances of a psychotic, neurotic, or behavioral nature also may
be present.
Brain Syndromes:
1. Acute
2. Chronic
2.Mental
Retardation 10. Other Disorders
This category is for
disorders that cannot be classified by the above definitions or for disorders
we will describe in the future.
