DSM-IV-TR Criteria for Pervasive
Developmental Disorders
Asperger’s Disorder (DSM code 299.80)
Qualitative impairment in social interaction, manifested by at least two of
the following:
• marked impairment in use of multiple nonverbal behaviors (eye-to-eye
gaze, facial expression, body postures, gestures)
• failure to develop peer relationships appropriate to developmental level
• lack of spontaneous seeking to share enjoyment, interests, or achievements
with others
• lack of social or emotional reciprocity
Restricted, repetitive, and stereotyped patterns of behavior, interests, and
activities, manifested by at least one of the following:

interest abnormal in either intensity or focus
• apparently inflexible adherence to specific, nonfunctional routines or
rituals
• stereotyped and repetitive motor mannerisms (hand or finger flapping,
complex whole-body movements)
• persistent preoccupation with parts of objects
Symptoms cause clinically significant impairment in social, occupational,
or other important areas of functioning
No clinically significant general delay in language
No clinically significant delay in cognitive development or development of
age-appropriate self-help skills, adaptive behavior (other than in social interaction),
and curiosity about environment
Criteria for another specific pervasive developmental disorder or schizophrenia

3) Restricted, repetitive, and stereotyped patterns of behavior, interests,

• preoccupation with one or more stereotyped and restricted patterns of
interest abnormal in either intensity or focus

Delays or abnormal functioning in at least one of the following areas, with
onset prior to age three:

Symptoms not better explained by Rett’s Disorder or Childhood Disintegrative
Disorder
Childhood Disintegrative Disorder (DSM code 299.10)
Apparently normal development until at least age two, with age-appropriate
verbal and nonverbal communication, social relationships, play, and adaptive
behavior
Clinically significant loss of previously acquired skills before age ten in at
least two of the following areas:
• expressive or receptive language
• social skills or adaptive behavior
• bowel or bladder control

• motor skills
At least two of the following abnormalities of functioning:
• qualitative impairment in social interaction (impairment in nonverbal
behaviors, failure to develop peer relationships, lack of social or emotional
reciprocity)
• qualitative impairments in communication (delay or lack of spoken language,
inability to initiate or sustain conversation, stereotyped and repetitive
use of language, lack of varied make-believe play)
• restricted, repetitive, and stereotyped patterns of behavior, interests,
and activities, including motor stereotypies and mannerisms
Symptoms not better explained by another specific pervasive developmental
disorder or schizophrenia

DSM-IV-TR Criteria for Pervasive
Developmental Disorders—continued
Rett’s Disorder (DSM code 299.80)
Apparently normal prenatal and perinatal development, apparently normal
psychomotor development through first five months after birth, and normal
head circumference at birth
Onset of all the following after the period of normal development:
• deceleration of head growth between five and forty-eight months of age
• loss of previously acquired purposeful hand skills between five and thirty
months of age, with the subsequent development of stereotyped hand
movements
• loss of social engagement early in course (although often social interaction
develops later)
• poorly coordinated gait or trunk movements
• severely impaired expressive and receptive language development, with
severe psychomotor retardation
