Sensory responsiveness as a predictor of social severity in children with high functioning autism spectrum disorders.

This study examines the relationship between sensory responsiveness and social severity in children with high functioning autism spectrum disorders (HFASD; N = 36) and age-matched controls (N = 26) between 6 and 10 years old. Significant relationships were found between social responsiveness scale scores and each of the six sensory profile sensory system scores for children with HFASD and controls. Multivariate regression analyses revealed atypical scores from multisensory responsiveness, and responsiveness of the proximal senses of oral sensory/olfactory and touch as the strongest predictors of greater social impairment in the participants. Findings suggest that the relationship between sensory responsiveness and other autistic traits is more important than previously recognized and addressing sensory modulation issues in children with HFASD may be more critical than previously understood.

Developmental course of autistic social impairment in males.

Recent research has suggested that autistic social impairment (ASI) is continuously distributed in nature and that subtle autistic-like social impairments aggregate in the family members of children with pervasive developmental disorders (PDDs). This study examined the longitudinal course of quantitatively characterized ASI in 3- to 18-year-old boys with and without PDD. We obtained assessments of 95 epidemiologically ascertained male-male twin pairs and a clinical sample of 95 affected children using the Social Responsiveness Scale (SRS), at two time points, spaced 1-5 years apart. Longitudinal course was examined as a function of age, familial loading for PDD, and autistic severity at baseline. Interindividual variation in SRS scores was highly preserved over time, with test-retest correlation of 0.90 for the entire sample. SRS scores exhibited modest general improvement over the study period; individual trajectories varied as a function of severity at baseline and were highly familial. Quantitative measurements of ASI reflect heritable traitlike characteristics. Such measurements can serve as reliable indices of phenotypic severity for genetic and neurobiologic studies, and have potential utility for ascertaining incremental response to intervention.

Guidelines for supervision, roles, and responsibilities during the delivery of occupational therapy services.

These guidelines about supervision, roles, and responsibilities are to assist in the appropriate utilization of occupational therapists, occupational therapy assistants, and occupational therapy aides and in the appropriate and effective provision of occupational therapy services. It is expected that occupational therapy services are delivered in accordance with applicable state and federal regulations, relevant workplace policies, the Occupational Therapy Code of Ethics (AOTA, 2005), and continuing competency and professional development guidelines.

A comparison study of psychiatric and behavior disorders and cognitive ability among homeless and housed children.

This study examined the association of homelessness and related factors with child psychiatric and behavior disorders (diagnosed with structured diagnostic interviews) and child cognitive ability (on the Kaufman Brief Intelligence Test) in a randomly selected sample of 157 homeless children and their mothers and a comparison of 61 housed children and their mothers. Homeless children had more disruptive behavior disorders and lower cognitive scores than housed children. In multivariate analyses, maternal verbal scores and child nonverbal scores were associated with child verbal ability; maternal education, homelessness, and child nonverbal scores were related to child behavior disorders.

Rapid quantitative assessment of autistic social impairment by classroom teachers.

OBJECTIVE: Teachers routinely observe children in the naturalistic social contexts of their classrooms and provide extremely important input in the evaluation of numerous psychiatric syndromes. Their precision in ascertaining and quantifying autistic symptomatology has not previously been established. In this study, we compared teachers' ratings of autistic symptomatology with those derived from parents, expert clinicians, and trained raters. METHOD: A total of 577 subjects (ages 4-18 years) with (n = 406) and without (n = 171) pervasive developmental disorders (PDDs) were assessed by one parent and one current teacher using the Social Responsiveness Scale, a quantitative measure of autistic traits. PDD subjects were assessed by expert clinicians, the Autism Diagnostic Interview-Revised, and/or the Autism Diagnostic Observation Schedule. All of the assessments were conducted during the period 1996-2006. RESULTS: Teacher Social Responsiveness Scale reports exhibited strong correlations with parent reports (0.72); use of quantitative ratings from both informants resulted in extremely high sensitivity and specificity for clinical and research diagnoses of PDDs (area under receiver operating characteristics curve = .95). CONCLUSIONS: Rapid quantitative assessments by teachers and parents constitute a cost-effective method for measuring and tracking the severity of autistic symptomatology in both educational and clinical settings.

Guidelines for supervision, roles, and responsibilities during the delivery of occupational therapy services (2004).

These guidelines about supervision, roles, and responsibilities are to assist in the appropriate utilization of occupational therapy personnel and in the appropriate and effective provision of occupational therapy services. All personnel are expected to meet applicable state and federal regulations, adhere to relevant workplace policies and the Occupational Therapy Code of Ethics (AOTA, 2000), and participate in ongoing professional development activities to maintain continuing competency.
