The psychometric properties of the Autism Behavior Checklist (ABC; Krug, Arick, & Almond, 1980a, 1980b), a 57-item screening checklist for autism was investigated. Professional Informants completed the ABC on 67 autistic and 56 mentally retarded and learning-disabled children. The autistic children were the total population of autistic children aged 6-15 in two circumscribed suburban and rural regions. Using the total score, the ABC accurately discriminated 91% of the children, with 87% of the autistic and 96% of the nonautistic group correctly classified. Moreover, the accuracy of classification was virtually identical when only the more heavily weighted checklist items were used. A 3-factor model accounted for 32% of the total variance in the checklist. Seventeen items loaded .4 or more on Factor 1, 12 items loaded on Factor 2, and 10 items loaded on Factor 3. The present results fail to provide empirical support for a single unidimensional scale for autism. Also, there is little support for subdividing the checklist into five subscales based on symptom areas.

This study evaluates the safety and efficacy of buspirone hydrochloride for the treatment of a patient with autism and hyperactivity disorder and determines the effect of buspirone on the number of performance tasks completed by the patient at school. A 3-week, double-blind, placebo-controlled crossover study was performed in a private physician, office-based practice. A child with autism, which was diagnosed by Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised, criteria, was studied. The child received placebo for 3 weeks and buspirone for 3 weeks; there was a 1-week interval between the 2 treatments. The outcome was measured by using Conners abbreviated parent and teacher questionnaires and by determining the number of daily performance tasks completed by the child at school. Statistical analysis was performed by linear models and standard F tests. Buspirone was found to be safe and efficacious, without side effects, for decreasing hyperactivity and increasing completed performance tasks. The beneficial effects of buspirone in helping this patient with autism in his natural daily settings suggest that buspirone may be an alternative to neuroleptic agents in the medical therapy of autism; further study in other patients is needed.

A genetic etiology in autism is now strongly supported by family and twin studies. A 3:1 ratio of affected males to females suggests the involvement of at least one X-linked locus in the disease. Several reports have indicated an association of the fragile X chromosomal anomaly at Xq27.3 (FRAXA) with autism, whereas others have not supported this finding. We have so far collected blood from 105 simplex and 18 multiplex families and have assessed 141 patients by using the Autism Diagnostic Interview-Revised (ADI-R), the Autism Diagnostic Observation Scale, and psychometric tests. All four ADI-R algorithm criteria were met by 131 patients (93%), whereas 10 patients (7%) showed a broader phenotype of autism. Southern blot analysis was performed with three different enzymes, and filters were hybridized to an FMR-1-specific probe to detect amplification of the CCG repeat at FRAXA, to the complete FMR-1 cDNA probe, and to additional probes from the neighborhood of the gene. No significant changes were found in 139 patients (99%) from 122 families, other than the normal variations in the population. In the case of one multiplex family with three children showing no dysmorphic features of the fragile X syndrome (one male meeting 3 out of 4 ADI-algorithm criteria, one normal male with slight learning disability but negative ADI-R testing, and one fully autistic female), the FRAXA full-mutation-specific CCG-repeat expansion in the genotype was not correlated with the autism phenotype. Further analysis revealed a mosaic pattern of methylation at the FMR-1 gene locus in the two sons of the family, indicating at least a partly functional gene. Therefore, we conclude that the association of autism with fragile X at Xq27.3 is non-existent and exclude this location as a candidate gene region for autism.

Asperger's Syndrome(AS) is a severe developmental disorder characterized primarily by marked and sustained difficulties in social interaction and unusual patterns of circumscribed interests and behavioral peculiarities. AS differs from autism primarily in that there is no general delay or retardation in language. A 3. 5 year-old boy with AS was referred for psychological assessment and treatment. When the boy was 23 months old, he was assessed with Bayley Scales of Infant Development (2nd ed.). Both MDI and PDI were within normal limits. After the referral, this boy was assessed with WPPSI-R and then prescribed 5 weekly intervention sessions consisting of communication skills training. At a one week's follow-up the boy was reassessed with Leiter-R. The results of WPPSI-R and Leiter-R showed the boy was in the normal intelligence range. From the second session to the fifth session, the boy's mother recorded 526 of his utterances. According to the analysis of these speech data, the language development for this boy was at Stage V, which indicated that his language development was in the superior range for his age. After 5 intervention sessions, the improvements in the child's communication skills were such that no further sessions were warranted. This boy might represent a case of aberrant neurofunctional organization. He has defects in perceptual organization but has good pattern recognition, which is based on features. It is theorized that his excellent verbal ability competed with the perceptual organization, so that he compensated for perceptual organization with verbal ability. An intervention designed to inhibit verbal compensation and facilitate configural processing is recommended.

LEGO building materials have been adapted as a therapeutic modality for increasing motivation to participate in social skills intervention, and providing a medium through which children with social and communication handicaps can effectively interact. A 3 year retrospective study of long-term outcome for autistic spectrum children participating in LEGO therapy (N = 60) compared Vineland Adaptive Behavior Scale socialization domain (VABS-SD) and Gilliam Autism Rating Scale social interaction subscale (GARS-SI) scores preand post-treatment with a matched comparison sample (N = 57) who received comparable non-LEGO therapy. Although both groups made significant gains on the two outcome measures, LEGO participants improved significantly more than the comparison subjects. Diagnosis and pre-treatment full-scale IQ scores did not predict outcome scores; however, Vineland adaptive behavior composite, Vineland communication domain, and verbal IQ all predicted outcome on the VABS-SD, especially for the LEGO therapy group. Results are discussed in terms of implications for methods of social skills intervention for autistic spectrum disorders.

A 3-part comprehensive synthesis of the early intensive behavioral intervention (EIBI) for young children with autism based on the University of California at Los Angeles Young Autism Project method (Lovaas in Journal of Consulting and Clinical Psychology, 55, 3-9, 1987) is presented. The three components of the synthesis were: (a) descriptive analyses, (b) effect size analyses, and (c) a meta-analysis. The findings suggest EIBI is an effective treatment, on average, for children with autism. The conditions under which this finding applies and the limitations and cautions that must be taken when interpreting the results are discussed within the contextual findings of the moderator analyses conducted in the meta-analysis.

Parents of children with autism often report gastrointestinal problems as well as picky eating and selective eating in their children. The purpose of this study was to evaluate the nutritional status and the nutrient intake in 111 Chinese children with autism, aged between 2 and 9 years. Anthropometric data were expressed as Z scores. A 3-day dietary recall was provided by the parents, and the data were compared with the national Dietary Reference Intakes (DRI) standards for Chinese children. The results showed that only nine of the autistic children (8.1%) were acute or chronically malnourished. From the remaining 102 patients, 67 (60.4%) were eutrophic and 35 (31.5%) had either overweight or obesity. Intakes of both calories and proteins were adequate in the vast majority of these children, but the calories from fat was lower than DRI in the same age group. The average intake of vitamin E and niacin exceeded 100% of DRI, and the intakes of vitamin B1 and B2, magnesium, and iron were between 80% and 90% of DRI range. However, the following nutrients did not meet the DRI requirements at all: vitamins A, B6 and C, folic acid, calcium, and zinc. Although growth was satisfactory in the vast majority of these children with autistic disorder, this study revealed serious deficiencies in the intakes of several vitamins and essential nutrients.

In many low and middle income countries where autism-related resources are scarce, interventions must rely on family and parents. A 3-month Parent-Child Training Program (PCTP) at Action For Autism, New Delhi, India is aimed at empowering and educating parents, encouraging acceptance of their child, and decreasing parent stress. Forty couples were asked to describe their child with autism using the Five Minute Speech Sample (FMSS), an open-ended narrative method, before and after the program. Parents described a wide range of child behaviors, primarily social and cognitive skills. While all families were of a relatively affluent strata compared to the general Indian population, there were nonetheless significant differences in parents' narratives based on their income levels. Coming into the program, parents with relatively less income focused on their child's immediate and material needs, while higher income parents discussed their parental roles and vision for society. After the PCTP, parents were more likely to reflect on their child beyond comparisons to 'normality,' and beyond the here-and-now. Mothers were more likely than fathers to reflect on themselves and their relationships with their child. Understanding parents' experiences and narratives is essential for the evaluation of interventions such as the PCTP, as Indian parents are incorporated into a growing global network of 'parents of children with autism.'

The effects of class-specific compound consequences embedded in an identity-matching task to establish arbitrary emergent relations were evaluated. A 3-year-old child with autism was taught identity relations between lowercase letters (Set 1) and uppercase letters (Set 2). A compound stimulus that consisted of an auditory component (dictated letter name) and a visual component (an uppercase letter for Set 1 or lowercase letter for Set 2) followed correct responses. All targeted arbitrary relations emerged (uppercase-lowercase, lowercase-uppercase, dictated name/uppercase, and dictated name/lowercase), suggesting that this procedure may be useful for teaching.
