The parents of 15 autistic boys with a nonverbal IQ of at least 80 were compared with a matched group of parents of normal boys on the Goldstein-Scheerer Object Sorting Test and the Bannister-Fransella Grid Test of Thought Disorder. It was necessary to control for social class effects as abnormal scores on the thought disorder tests were more frequent in parents of manual social class. It was found that (a) there was a lack of agreement between the two tests of thought disorder, (b) the parents of autistic children showed thought disorder scores closely comparable to those of the parents of normals, and (c) there was no consistent association between thought disorder and anxiety. The methodological and substantive implications of the findings are discussed in relation to the results of previous investigations.

Twenty-six psychotic children were examined by means of psychological tests and EEGs. The parents of these patients were also tested with the EPI and the Grid Test of Thought Disorder. The mothers of children with the symptom of autism tended to have some cognitive disorganization, which was less common in the mothers of children without the symptom. The extraversion and neuroticism scores of all parents were not markedly different from population statistics. The incidence of EEG abnormality in the children was high and not related to diagnosis or other criteria. These findings are interpreted as providing suggestive evidence for a two-factor theory of childhood psychosis. It is postulated that a neurological disorder is a necessary condition for the development of such a disorder; and that a second process related to parental characteristics is also involved, which has the effect of determining the particular symptomatic manifestations seen in the psychotic child.

The present paper provides a brief history of the development of the DSM-III-R (American Psychiatric Association [APA], 1987) section on Pervasive Developmental Disorders. It describes the process by which the contents of the text and criteria for Autistic Disorder and Pervasive Developmental Disorder Not Otherwise Specified were decided and gives the reasons for the changes from DSM-III (APA, 1980) categories and criteria. The paper concludes with a short discussion of critical diagnostic issues.

This study compared four systems for the diagnosis of autism (DSM-III, DSM-III-R, DSM-IV, and ICD-10) with two empirically derived taxa of autism, and with three social subgroups of autism (Aloof, Passive, and Active-but-Odd) in 194 preschool children with salient social impairment. There were significant behavior and IQ differences between autistic and other-PDD groups for all four diagnostic systems, and a significant association was found (a) for Taxon B, diagnoses of autism, and the Aloof subgroup, and (b) for Taxon A, other-PDD, and the Active-but-Odd subgroup. Findings offer support for two major overlapping continua within idiopathic Pervasive Developmental Disorder.

Revised versions of diagnostic manuals, the International Classification of Diseases (ICD-10), and the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) all operate with several subgroups in the autistic spectrum. Five of the subgroups are identical in the two manuals, but ICD-10 contains five in addition. 132 children were diagnosed using ICD-10, DSM-IV, DSM-III-R, the Childhood Autism Rating Scale (CARS), and the Autistic Behavior Checklist (ABC). Five out of ten alternative subgroups of Pervasive Developmental Disorders (PDD) were identified in a population of developmentally impaired children. These subgroups were the same in the two manuals; the additional ones in ICD-10 were not identified. With the exception of the groups Disintegrative Disorder and Rett syndrome, significant differences were found between all the subgroups within the PDD spectrum and between the PDD group and the non-PDD group. Some problems connected with the guidelines in the ICD-10 manual are discussed.

With publication of the fourth edition of the Diagnostic and statistical manual of mental disorders (DSM-IV), standardized criteria for Asperger Disorder, a putative subtype of Pervasive Developmental Disorder, are now available. This paper examines the four cases Asperger originally presented in his seminal paper (1991/1994), using DSM-IV criteria to determine whether a diagnosis of Autistic or Asperger Disorder is most appropriate. We found that all four cases met DSM-IV criteria for Autistic Disorder, rather than Asperger Disorder. This suggests that the syndrome Asperger originally described may not be captured by present diagnostic criteria. Implications for future research are discussed.

The first experiment involved 143 individuals with severe and profound mental retardation. Individuals with Stereotypic Movement Disorder, Self-Injurious Behavior (SIB), and Stereotypic movement disorder with self-injurious behavior as assessed by the Diagnostic Assessment for the Severely Handicapped-II DASH-II were validated against Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994) criteria. In a second study DASH-II scores for 1480 individuals with severe and profound mental retardation were compared on demographic variables, core and associated features of each disorder. Characteristics of persons in each group were reviewed. Persons with profound mental retardation were more likely to evince stereotypies or self-injury compared to their severely impaired counterparts. Also, those with stereotypies were more likely to present with Pervasive Developmental Disorder (PDD)/autism, organicity, and eating disorders, while persons with SIB were more likely to evince sleep, sexual, and eating disorders.

Within the last decade, researchers and clinicians have reported an increase in the incidence and diagnosis of Autism Spectrum Disorder (ASD). Various factors have been proposed for this apparent change including broader diagnostic criteria, greater public awareness, biological and environmental interactions, and earlier detection. However, it has been observed in a certain percentage of children, during the toddler and preschool years and before intervention is introduced, that severe language deficits distort social and self-regulatory behavior to such a degree that they mimic the characteristics of ASD. Professional caution is vital in this regard to describe early functioning and to defer diagnosis until the effects of intervention and treatment can be monitored over time. The case of Nicole, a preschooler with developmental delays and social communication oddities, illustrates what I believe is the most professionally responsible, cautious, family-centered, and data-based diagnostic process that links assessment, intervention, and evaluation for young children with early developmental difficulties.

This study was designed to establish the empirical validity of the Diagnostic Assessment for the Severely Handicapped-II (DASH-II) to screen for the presence of autism in severely and profoundly mentally retarded adults. Participants included 51 individuals residing in a large developmental center in Central Louisiana. The Autism/Pervasive Developmental Disorder subscale of the DASH-II was internally consistent. Additionally, the DASH-II was just as likely as the Childhood Autism Rating Scale (CARS) to classify autistic and control individuals. Specific items on the subscale were examined to identify those items most associated with a diagnosis of autism.

Comprehensive data on the developmental history and current behaviours of a large sample of high-functioning individuals with diagnoses of autism, Asperger's syndrome, or other related disorder were collected via parent interviews. This provided the basis for a taxonomic analysis to search for subgroups. Most participants also completed theory of mind tasks. Three clusters or subgroups were obtained; these differed on theory of mind performance and on verbal abilities. Although subgroups were identified which bore some relationship to clinical differentiation of autistic, Asperger syndrome, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) cases, the nature of the differences between them appeared strongly related to ability variables. Examination of the kinds of behaviours that differentiated the groups suggested that a spectrum of autistic disorders on which children differ primarily in term of degrees of social and cognitive impairments could explain the findings.
