While the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is considered a "reference standard" measure to observe symptoms of autism spectrum disorder (ASD), little is known about the utility of its Other Abnormal Behaviors or "E codes." This study investigated the unique influence of each E code (overactivity,…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Autism spectrum disorder (ASD) is characterized by a variety of social and non-social behavioral deficits. One potential mechanism that could unify this diverse profile of behaviors is slower processing speed. Seventy-six high-functioning adults with ASD were compared to 64 matched controls on standardized measures of processing speed.…

This study was a replication of Mazefsky et al.'s ("Journal of Autism and Developmental Disabilities" 43:1236-1242, 2013) investigation among a sample of 45 high ability children and adolescents diagnosed with ASD under DSM-IV-TR. Items from the ADOS and ADI-R were mapped onto DSM-5 diagnostic criteria for ASD and SCD to determine…

We examined the relationship between sleep duration and awakenings to Aberrant Behavior Checklist-Community (ABC-C) and Autism Diagnostic Observation Schedule (ADOS-2) scores in hospitalized youth with ASD and behavioral disturbance. Participants included 106 patients with a stay of at least 10 nights. Sleep in the hospital was recorded by staff…

Few tools are available to comprehensively describe the unique social-emotional skill profiles of youth with autism spectrum disorder (ASD). The present study describes the usability, reliability, and validity of SELweb, a normed, web-based assessment designed to measure four core social-emotional domains, when used to measure these skills in a…

Autistic traits are associated with frequent psychological distress, suicidal ideation, and everyday functional challenges. These associations may be especially prominent in women. Some women with autistic traits "camouflage" feelings of awkwardness in typical social situations by effortfully engaging in expected social behaviors. We…

Individuals with autism spectrum disorder (ASD) tend to have significant delays in adaptive functioning. In this study, the relationship between adaptive behavior and ASD symptomatology was investigated in minimally verbal, school-aged children with ASD (n = 333). Both the social affect (SA) and restricted and repetitive behavior (RRB) domains…

Differences in behavioral and cognitive profiles have been suggested to potentially impact the presentation of social and communication symptoms in females with autism spectrum disorder. This study examined gender differences in age of diagnosis, cognitive profiles, social communication symptomatology, and autism spectrum disorder symptom severity…

Toddlers with autism spectrum disorder (ASD) were assessed on the Repetitive Behavior Scale-Revised (RBS-R), which we found to have acceptable internal consistency. Stereotypical subscale scores showed a negligible association with cognitive level, but correlated more strongly with adaptive and social indicators. Relative to earlier reported RBS-R…

Standardized Autism Diagnostic Observation Schedule (ADOS) scores provide a measure of autism severity that is less influenced by child characteristics than raw totals (Gotham et al. in "Journal of Autism and Developmental Disorders," 39(5), 693-705 2009). However, these scores combine symptoms from the Social Affect (SA) and Restricted…

A network conceptualization might contribute to understanding the occurrence and interacting nature of behavioral traits in the autism realm. Networks were constructed based on correlations of item scores of the Autism Diagnostic Observation Schedule for Modules 1, 2 and 3 obtained for a group of 477 Dutch individuals with developmental disorders.…

The Social Responsiveness Scale (SRS) is currently being used in clinical and genetic studies of autism as both a screener and as a quantitative measure of autistic traits. This article assesses the influence of nonspecific factors on SRS scores to aid researchers in their interpretations of these scores. In their commentary, Constantino and…

The new DSM-5 dimensional framework of Autism Spectrum Disorders (ASD) features severity ratings of social communication (SC) and restrictive/repetitive behaviors (RRB) and little research has been conducted since its inception. There has been a recent increase in the administration and adoption of broadband behavior-rating scales by clinicians,…

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…
