Late language emergence (LLE) may result from genetic and environmental factors. Little is known about environmental factors in LLE in South Africa. The study describes the nature of differences in language functioning between toddlers with LLE and without LLE, and which factors were associated with LLE in a middle-income area in South Africa.…

A gap exists in the literature regarding aggression in autism spectrum disorders and how this behavior compares to other groups. In this multisite study, the "Children's Scale for Hostility and Aggression: Reactive/Proactive" and the Aggression subscale of the "Child Behavior Checklist" were rated for 414 children with autism…

We compared ratings on the Three-Item Direct Observation Screen test for autism spectrum disorders completed by pediatric residents with the Social Communication Questionnaire parent reports as an augmentative tool for improving autism spectrum disorder screening performance. We examined three groups of children (18-60 months) comparable in age…

The study examines the epidemiology of oppositional defiant disorder (ODD) for children with intellectual disabilities (ID; n = 49), children with borderline intellectual functioning (BIF; n = 20), and typically developing children (TD; n = 115). The Diagnostic Interview Schedule for Children was administered to mothers at child ages 5, 6, 7, 8,…

Authors contrasted Bracken Basic Concept Scale: Receptive, Third Edition (BBCS: R-3) test performance between 57 children with intellectual disability (ID) and 76 children with autism spectrum disorder (ASD) and ID. BBCS: R-3 School Readiness Composite (SRC) and Self-/Social Awareness subtests were analyzed. Multivariate analysis of covariance…

This study examines the academic abilities of children and adolescents who were once diagnosed with an autism spectrum disorder, but who no longer meet diagnostic criteria for this disorder. These individuals have achieved social and language skills within the average range for their ages, receive little or no school support, and are referred to…

Profiles of performance on the Stanford Binet Intelligence Scales (SB5) and Vineland Adaptive Behavior Scales (VABS) were examined in 73 children and adolescents with autism spectrum disorder. SB5 cognitive profiles were observed to be similar between participants with and without early language delay, but different between participants with and…

The Vineland Adaptive Behavior Scale was administered to 54 children diagnosed with autism spectrum disorder (ASD) before age 2, and a matching group of 18 toddlers with developmental delay (DD). The group with ASD was more impaired on all scales of the Vineland than DD peers. When 18 ASD/DD pairs very closely matched on age, verbal and nonverbal…

The Autism Spectrum Disorder Observation for Children (ASD-OC) is a 45-item observation scale used to assess autistic symptomatology. The reliability of this measure has been established in previous research; therefore, the purpose of this study is to evaluate its validity among a sample of children (1-15 years). The large correlation between the…

The Social Attribution Task, Multiple Choice is introduced as a measure of implicit social cognitive ability in children, addressing a key challenge in quantification of social cognitive function in autism spectrum disorder, whereby individuals can often be successful in explicit social scenarios, despite marked social adaptive deficits. The…

The study examined teasing experiences among 74 individuals with autism spectrum disorder (ASD; M age = 115.7 months [9.6 years]; 83.8% male). Experiences were examined from parent, teacher, and child's own perspectives. Factors potentially associated with being teased were investigated. Comparison data were ascertained on typically developing…

In order to investigate unique and shared characteristics and to determine factors predictive of group classification, quantitative comparisons of behavioral and emotional problems were assessed using the Developmental Behavior Checklist (DBC-P) and the Vineland Adaptive Behavior Scales in autistic disorder, Williams syndrome (WS), and…
