We measured skin conductance response (SCR) to escalating levels of a direct social threat from a novel, ecologically-relevant experimental paradigm, the Intruder Threat Task. We simultaneously evaluated the contribution of social symptom severity and behavioral movement. Children with AS group showed less psychophysiological reactivity to social threat than controls across all three phases of the experiment. In the AS group, greater social impairment was significantly associated with reduced SCR. However, movement activity predicted SCR while diagnosis did not...

We re-evaluate conclusions about disfluency production in high-functioning forms of autism spectrum disorder (HFA). Previous studies examined individuals with HFA to address a theoretical question regarding speaker- and listener-oriented disfluencies. Individuals with HFA tend to be self-centric and have poor pragmatic language skills, and should be less likely to produce listener-oriented disfluency. However, previous studies did not account for individual differences variables that affect disfluency. We show that both matched and unmatched controls produce fewer repairs than individuals with HFA...

Preschool-aged siblings of children with ASD are at high-risk (HR) for ASD and related challenges, but little is known about their emerging peer competence and friendships. Parents are the main providers of peer-relationship opportunities during preschool. Understanding parental challenges supporting early peer relationships is needed for optimal peer competence and friendships in children with ASD. We describe differences in peer relationships among three groups of preschool-aged children (15 HR-ASD, 53 HR-NonASD, 40 low-risk, LR), and examine parent support activities at home and arranging community-based peer activities...

Parenting children with ASD has a complex history. Given parents' increasingly pivotal role in children's treatment, it is critical to consider parental style and behaviours. This study (1) compares parenting style of parents of children with ASD, parents of children with anxiety disorders, and parents of typically developing (TD) children and (2) investigates contributors to parenting style within and between groups. Parents of children with anxiety had a distinct parenting style compared to ASD and TD parents...

Elucidating the heterogeneous etiologies of autism will require investment in comprehensive longitudinal data acquisition from large community based cohorts. With this in mind, we have established a hospital-university-based (HUB) database of autism which incorporates prospective and retrospective data from a large and ethnically diverse population. The collected data includes social-demographic characteristics, standardized behavioral testing, detailed clinical history from electronic patient records, genetic samples, and various neurological measures...

Little is known about suicidal ideation in youth with autism spectrum disorder (ASD), making it difficult to identify those at heightened risk. This study describes the prevalence of thoughts about death and suicide in 107 verbal youth with ASD with non-verbal IQ >55, assessed during inpatient psychiatric admission. Per parent report, 22% of youth with ASD had several day periods when they talked about death or suicide "often," or "very often." Clinical correlates included the presence of a comorbid mood (OR 2...

High functioning adolescents with Autism Spectrum Disorder (ASD) often have adjustment difficulties, specifically loneliness and depression. To better understand contributing factors, the current study evaluated associations between several Executive Function (EF) domains, social impairment, and friendship quality on depressive symptoms and loneliness in this population. Participants included 127 high functioning ASD adolescents and a parent/caregiver. Results indicated significant levels of parent-reported EF impairment which were positively correlated with increased levels of loneliness and depressive symptoms...

The impact of ASD on parental QOL was evaluated in the EpiTED cohort study at early adulthood. Two-third of parents of young adults with ASD (66.7%) reported that their QoL was at least moderately altered. The perceived impact of ASD on parental QoL was related to the young adults' level of adaptive skills, as well as to symptom severity and the presence of challenging behaviors, which appeared to be the main risk factor. The study of change between adolescence and early adulthood showed that parents whose children had a decrease in challenging behaviors perceived a decreased impact on their QoL...

This study of 8-16-year-olds was designed to test the hypothesis that reading comprehension impairments are part of the social communication phenotype for many higher-functioning students with autism spectrum disorder (HFASD). Students with HFASD (n = 81) were compared to those with high attention-deficit/hyperactivity disorder symptomatology (ADHD; n = 39), or typical development (TD; n = 44), on a comprehensive battery of oral language, word recognition, and reading comprehension measures. Results indicated that students with HFASD performed significantly lower on the majority of the reading and language tasks as compared to TD and ADHD groups...

The transition from DSM-IV to DSM-5 criteria for autism spectrum disorder (ASD) sparked considerable concern about the potential implications of these changes. This study was designed to address limitations of prior studies by prospectively examining the concordance of DSM-IV and final DSM-5 criteria on a consecutive sample of 439 children referred for autism diagnostic evaluations. Concordance and discordance were assessed using a consistent diagnostic battery. DSM-5 criteria demonstrated excellent overall specificity and good sensitivity relative to DSM-IV criteria...

Social media holds promise as a technology to facilitate social engagement, but may displace offline social activities. Adolescents with ASD are well suited to capitalize on the unique features of social media, which requires less decoding of complex social information. In this cross-sectional study, we assessed social media use, anxiety and friendship quality in 44 adolescents with ASD, and 56 clinical comparison controls. Social media use was significantly associated with high friendship quality in adolescents with ASD, which was moderated by the adolescents' anxiety levels...

In addition to social communication deficits, restricted repetitive behaviors (RRBs) are a key diagnostic feature of autism spectrum disorder (ASD). Dysfunction of the autonomic nervous system (ANS) in ASD has been posited as a mechanism of RRBs; however, most studies investigating ANS activity in ASD have focused on its relation to social functioning. This study used respiratory sinus arrhythmia (RSA) patterns to measure ANS functioning and analyze its relation to RRBs in children with and without an ASD diagnosis...

Here we report the feasibility and acceptability of telehealth for direct intervention in children with Prader-Willi syndrome (PWS). Children with PWS have social-cognitive challenges that are similar to children with ASD. However, developing behavioral interventions for individuals with PWS is faced with the significant challenge of enrolling enough participants for local studies where multiple visits per week are indicated for effective intervention. This study delivered a 6-week play-based intervention via telehealth directly to eight children with PWS (6-12 years)...

This study aimed to describe police interactions, satisfaction with police engagement, as well as examine correlates of police involvement among 284 adolescents and adults with autism spectrum disorder (ASD) followed over a 12- to 18-month period. Approximately 16% of individuals were reported to have some form of police involvement during the study period. Aggressive behaviors were the primary concern necessitating police involvement. Individuals with police involvement were more likely to be older, have a history of aggression, live outside the family home, and have parents with higher rates of caregiver strain and financial difficulty at baseline...

This study compared sexual orientation and romantic relationship experience in a large sample of adolescents and adults with autism spectrum disorder (ASD) (n = 675) and general population peers (n = 8064). Gender identity was explored in the ASD group in relation to assigned gender at birth. Compared to general population peers, more people with ASD, especially women, reported sexual attraction to both same- and opposite-sex partners. About half of the participants with ASD was in a relationship (heterosexual in most cases) and most of them lived with their partner...

Theory of mind (ToM) is impaired in individuals with autism spectrum disorders (ASD). The aims of this study were to: (i) examine the developmental trajectories of ToM abilities in two different mentalizing tasks in children with ASD compared to TD children; and (ii) to assess if a ToM simple test known as eyes-test could predict performance on the more advanced ToM task, i.e. comic strip test. Based on a sample of 37 children with ASD and 55 TD children, our results revealed slower development at varying rates in all ToM measures in children with ASD, with delayed onset compared to TD children...

Previous work shows that doing a continuous performance task (CPT) shifts attentional biases in neurotypical individuals towards global aspects of hierarchical Navon figures by selectively activating right hemisphere regions associated with global processing. The present study examines whether CPT can induce similar modulations of attention in individuals with high levels of autistic traits who typically show global processing impairments. Participants categorized global or local aspects of Navon figures in pre- and post-CPT blocks...

The Autism Diagnostic Observation Schedule (ADOS) is widely used to assess symptoms of autism spectrum disorder (ASD). Given well-documented differences in social behaviors across cultures, this study examined whether item-level biases exist in ADOS scores across sociodemographic groups (race, ethnicity, and gender). We examined a subset of ten ADOS items among participants (N = 2458). Holding level of overall ADOS behavioral symptoms constant, we found significant item level bias (measurement noninvariance) for race and ethnicity on three ADOS items...

Data from the Autism Inpatient Collection was used to examine the relationship between problem behaviors and verbal ability, which have generally, though not universally, been highly associated. In a comparison of 169 minimally-verbal and 177 fluently-verbal 4 to 20-year-old psychiatric inpatients with ASD, the severity of self-injurious behavior, stereotyped behavior, and irritability (including aggression and tantrums) did not significantly differ, when controlling for age and NVIQ. Verbal ability was not strongly related to the severity of problem behaviors...

Altered patterns of sensory responsiveness are a frequently reported feature of Autism Spectrum Disorder (ASD). Younger siblings of individuals with ASD are at a greatly elevated risk of a future diagnosis of ASD, but little is known about the neural basis of sensory responsiveness patterns in this population. Younger siblings (n = 20) of children diagnosed with ASD participated in resting electroencephalography (EEG) at an age of 18 months. Data on toddlers' sensory responsiveness were obtained using the Sensory Experiences Questionnaire...
