The Kiddie-Infant Descriptive Instrument for Emotional States (KIDIES), a new instrument that uses affective and behavioral dimensions for categorization, was compared with DSM-III-R criteria to assess diagnostic reliability in childhood pervasive developmental disorder (PDD). Forty-two children with PDD and other developmental disorders were evaluated. Their diagnoses were based on DSM-III-R criteria. Subjects were videotaped during interviews with three different partners and rated using the KIDIES. Cluster analysis of KIDIES ratings revealed a significant correlation with DSM-III-R diagnostic categories, demonstrating the potential reliability of the KIDIES dimensional approach for diagnosing PDD in preschoolers.
An investigation of children with pervasive developmental disorder (PDD) was conducted using a new instrument, the Kiddie-Infant Descriptive Instrument for Emotional States (KIDIES). The KIDIES rates several affective and behavioral dimensions based on facial, vocal, gestural, and postural cues. The study's goals were to determine whether the KIDIES could detect individual differences in responsivity among the PDD subjects; to ascertain the KIDIES' sensitivity in identifying group differences between PDD subjects and control children with other developmental disorders. Children were videotaped during episodes with three partners: the mother, a familiar female teacher, an unfamiliar male doctor. Episodes were scored using the KIDIES. PDD subjects were most severely impaired during the Mother episode in comparison to the controls. Equally as striking was the within-episode heterogeneity among PDD subjects. During the Teacher episode, PDD subjects were twice as variable in interpersonal response as the controls.
The Kiddie-Infant Descriptive Instrument for Emotional States (KIDIES) was used to overcome the limitations of microanalytic facial observations and subjective assessments in the diagnosis of childhood developmental disorders. The KIDIES quantifies eight behavioral and eight affective dimensions by evaluating facial, vocal, gestural, and postural displays. In a sample of 42 subjects, KIDIES ratings distinguished between children with pervasive developmental disorder and a comparison group with mixed developmental diagnoses, and demonstrated sensitivity to emotional changes as a result of environmental shift. The results suggest that the KIDIES has potential as a reliable instrument for evaluating emotional and behavioral patterns in young developmentally disordered children.
A 4-year-old girl presented for a psychiatric evaluation with reported episodes of clumsiness, aggressiveness, lack of relatedness, and temper tantrums. Her evaluation disclosed multiple developmental deficits, including cognitive, affective, and social lags. Given her individual history and her specific constellation of symptoms as well as a familial history indicative of developmental impairment, the child was diagnosed as having pervasive developmental disorder. This diagnosis reflects the expanded nosology for autism, as specified in DSM-III-R. Subsequently, after a genetic evaluation, the child was found to have an organic central nervous system deficit in the form of cerebral gigantism, a neural disorder. The recognition of an organic impairment in this case contributed to an understanding of the pervasive developmental disorder symptomatology and facilitated the formulation of an appropriate therapeutic protocol that addressed both developmental and neurological components.

Infants and young children often from tenacious, persistent attachments to soft objects. No investigation has focused, specifically, on an older school-aged population. Data were collected from parents of 171 normal children between 9 and 13 years of age from the middle to upper socioeconomic class. The study (1) compared current behavioral characteristics of children with or without a history of attachment; (2) compared the current behavioral characteristics of the children who have or have not maintained that attachment; (3) explored the relationship between parental attitudes and the persistence or disappearance of the object; and (4) explored family demographics and object use among siblings. Approximately half (54%) had formed an attachment to an object in infancy. Of the group of "users" approximately half kept it until age 9 years (49%). There were no significant behavioral differences among those children who were or were not attached to an object, or among those children who continued to use a soft object after age 9 years compared to those who never used one at all. Parents felt they had little to do, directly, with their child's relinquishing the object. Sibling use, the number of siblings, ordinal rank of the child, parents' marital status, sex of the child, and history of thumb-sucking were all unrelated to object attachment.
