Purpose: The study objective was to determine if the validated Behavioral Inflexibility Scale (BIS) is sensitive to the detection of developmental changes in inflexibility in a sample of autistic children. Methods: Parents of autistic children (n = 146, 3-17 years) completed the BIS at two time points, one year apart, to examine change. Results:…

Toward the development of a new parent-rating for insomnia, this multi-site qualitative study explored sleep problems and related impacts in children with autism spectrum disorder (ASD) and their families. To ensure content validity of the measure, we conducted six focus groups with caregivers (N = 25) of 24 children (age 3 to 18 years) with ASD.…

The interactions between sleep problems, autism symptoms and emotional and behavioural difficulties were explored using network analysis in 240 autistic children (mean age: 8.8 years, range 5-13 years) with moderate to severe sleep problems. Findings revealed a highly connected and interpretable network, with three separate clusters identified of…

Recent research suggests there may be differences in the social presentations of autistic males and females. Camouflaging is believed to account for some of these differences and executive function (EF) may support compensatory social behaviors. As few studies have explored the role of sex and everyday EF when evaluating specific social…

Parents of children with autism spectrum disorder (ASD) often experience elevated levels of caregiver strain (CGS). Few studies have examined the relationship between core ASD symptoms and each facet of CGS: objective, subjective internalized, and subjective externalized strain. The predictive effect of core and associated features of ASD on CGS…

This was an exploratory cross-sectional study comparing 45 children with ASD to 24 typically developing drug-naïve controls, group-matched on age, sex, and body mass index. Objective data was obtained using the following: an ambulatory circadian monitoring device; saliva samples to determine dim light melatonin onset (DLMO): and three…

This study examined differences in mother-child relationship quality and parent-rated child behavior problems based on child verbal status (i.e., minimally verbal versus verbal) in mothers and their adolescent and adult children with autism spectrum disorder (n = 219 dyads; child M[subscript age] = 25.38 years, SD = 10.22). Relationship quality…

The Eyberg Child Behavior Inventory (ECBI) is a frequently used measure to assess interfering behaviors in children and psychometric properties have recently been examined in children with autism spectrum disorder (ASD). There is a need to confirm the identified factors and examine the factor structure in a racially/ethnically diverse,…

PEERS® for Adolescents is an evidence-based social skills intervention for autistic youth and adolescents with other social challenges. The efficacy and effectiveness of PEERS® are well established; however, limited data on PEERS® via telehealth delivery exist. The current study aimed to examine the efficacy of PEERS® for Adolescents via…

There is increasing concern regarding additional psychiatric problems that co-occur with Autism Spectrum Disorder (ASD), as reflected in recent changes to diagnostic schemes. However, there remains little research with population-based samples across childhood. We report on additional problems, as measured by the Strengths and Difficulties…

Research indicates that children with autism spectrum disorder (ASD) frequently exhibit dysregulation, which refers to poorly coordinated affective, behavioral, and cognitive responses to a given situation. We examined the characteristics of dysregulation in children presenting to a multidisciplinary ASD clinic for an ASD diagnostic evaluation.…

Behavior problems in children with autism spectrum disorder (ASD) may exacerbate parenting stress. Parenting self-efficacy and family resources may influence this association. We examined cross-sectional statistical mediation effects of parenting self-efficacy on the relationship between child behavior problems and parenting stress and…

Purpose: The Program for the Education and Enrichment of Relational Skills (PEERS®) is a group-based social skills training program for adolescents on the autism spectrum. Although the program has been shown to be effective in improving social skills in autistic adolescents, evidence of its effectiveness from the Mandarin-speaking Chinese…

There are currently no approved pharmacological treatments to improve social reciprocity and limit repetitive and rigid behaviors in autism spectrum disorder (ASD). We describe the design of two Phase III studies evaluating the efficacy/safety of bumetanide oral liquid formulation in ASD. These are international, multicenter, randomized,…

There is limited research on the trajectory of restricted and repetitive behaviors (RRBs) in fragile X syndrome (FXS), with previous studies only examining males and/or examining RRBs as a unitary construct rather than delineating subtypes of RRBs. Thus, we described the trajectory of five subtypes of RRBs in 153 males and females with FXS (aged…
