Heart rate variability (HRV) was measured simultaneously to study potential impairments in the autonomic nervous system (ANS) associated with ASD. The results showed that the ASD group had significantly longer PLR latency, reduced relative constriction amplitude, and shorter constriction/redilation time than those of the TD group. Similar atypical PLR parameters were observed in the NDD group. A significant age effect on PLR latency was observed in children younger than 9 years in the TD group, but not in the ASD and NDD groups. Atypical HRV parameters were observed in the ASD and NDD groups. A significant negative correlation existed between the PLR constriction amplitude and average heart rate in children with an ASD, but not in children with typical development.

Brief Report: A Preliminary Study of the Relationship between Repetitive Behaviors and Concurrent Executive Function Demands in Children with Autism Spectrum Disorder / Mackenzie N. CISSNE in Journal of Autism and Developmental Disorders, 52-4 (April 2022)

An eye movement task was used to evaluate inhibition and task switching ability (both together and in isolation) in a sample of 22 children with autism spectrum disorder (ASD). The Repetitive Behavior Scale-Revised (RBS-R) was used to assess the severity of RBRI symptoms. Results provide preliminary support for the aforementioned hypothesis. RBS-R scores were significantly correlated with task performance when simultaneous demands were placed on switching and inhibition; however, no such relationship was found for inhibition-only or switching-only task conditions.

Inhibitory Control in Children with Autism Spectrum Disorder / Shawn E. CHRIST in Journal of Autism and Developmental Disorders, 37-6 (July 2007)

It remains unclear, however, whether such individuals also experience impairments in another executive ability: inhibitory control. In the present study, we administered three inhibitory tasks to 18 children with ASD, 23 siblings of children with ASD, and 25 typically developing children. After controlling for individual differences in age, overall IQ, and processing speed, children with ASD demonstrated impaired performance on two of the three inhibitory tasks. Results suggest that children with ASD experience circumscribed deficits in some but not all aspects of inhibitory control. More generally, the findings underscore the importance of using multiple measures to assess a putative single cognitive ability.

Psychiatric Symptoms and Psychosocial Difficulties in Young Adults with Autistic Traits / Stephen M. KANNE in Journal of Autism and Developmental Disorders, 39-6 (June 2009)

A group reporting minimal autism traits was also identified (Low SRS group) matched for age, gender, and attentional difficulties. We administered the Behavioral Assessment System for Children—2nd edition (BASC-2), a comprehensive questionnaire designed to assess psychiatric symptoms and personality characteristics, to both groups. The high SRS group reported significantly more difficulties across the majority of areas, including depression/anxiety, interpersonal relationships, and personal adjustment. Thus, young adults reporting a greater degree of autistic traits also reported greater psychiatric difficulties across a wide psychosocial range.

The Subthreshold Autism Trait Questionnaire (SATQ): Development of a Brief Self-Report Measure of Subthreshold Autism Traits / Stephen M. KANNE in Journal of Autism and Developmental Disorders, 42-5 (May 2012)

An initial item pool was administered to 1,709 students. Structural validity analysis resulted in a 24-item questionnaire termed the Subthreshold Autism Trait Questionnaire (SATQ; Cronbach’s alpha coefficient = .73, test–retest reliability = .79). An exploratory factor analysis suggested 5 factors. Confirmatory factor analysis indicated the 5 factor solution was an adequate fit and outperformed two other models. The SATQ successfully differentiated between an ASD and student group and demonstrated convergent validity with other ASD measures. Thus, the current study introduces and provides initial psychometric support for the SATQ.
