To determine whether a gluten-free diet (GFD) compared with a gluten-containing diet (GD) influences functioning of children with autism spectrum disorders (ASD), we performed a randomized, controlled, single-blinded trial. Sixty-six children (36-69 months) with ASD, within the normal IQ (> 70) range, who had been on a GFD for at least 8 weeks…

Researchers are often inclined to test agreement or discrepancy hypotheses using difference scores. This commentary explains 2 mathematical-statistical principles underlying associations with difference scores and 2 conceptual-interpretation problems that make difference scores inappropriate for testing such hypotheses. The commentary provides…

Research on follow-up outcomes of systemic interventions for family members with an intellectual disability is scarce. In this study, short-term and long-term follow-up outcomes of multisystemic therapy for adolescents with antisocial or delinquent behaviour and an intellectual disability (MST-ID) are reported. In addition, the role of parental…

When a student exhibits challenging classroom behaviors that are resistant to traditional classroom management systems, his/her individualized education program (IEP) team conducts a functional behavior assessment (FBA). The FBA process is a series of assessments designed to identify the function of the student's behavior. This is done by…

The current study explored cross-sectional relations between coparenting quality and child problem behaviors, as measured by parent report and direct observation, in families of school-aged children previously identified with a developmental delay in early childhood. Parents' reports of difficulty with coparenting problems predicted child problem…

Background: Risk factors for poor school functioning rarely occur in isolation, but instead are likely to cluster together. As they accumulate, cumulative risk theory (CRT) predicts that the likelihood of negative outcomes increases, often disproportionately. Aims: We build upon and extend previous research by (i) examining two critical aspects of…

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are at a higher risk of experiencing bully victimization compared with peers with and without disabilities. Yet the association between ADHD subtypes and bully victimization is not well understood. The current study examines which set of behaviors related to ADHD subtypes is influential…

High probability request (high-"p") sequences, based on the momentum of behavior principle, have been an effective intervention for improving compliance and work completion for students who display challenging behaviors. They have been portrayed as a low-intensity intervention because of being perceived as simple, clear, and easy for any…

"Six Shifts to Improve Special Education and Other Interventions" offers a set of bold, new ideas for dramatically raising the achievement of students with mild to moderate disabilities and students experiencing serious academic, social and emotional, and behavioral difficulties. Despite much effort and caring on the part of educators, a…

When results of descriptive functional behavior assessments (FBAs) are inconclusive, experimental analysis methods can be used to directly test hypotheses about when or why a student engages in challenging behavior. Despite growing research on practical variations of hypothesis testing in schools, these methods are rarely incorporated in FBAs in…

Background: Pivotal response treatment (PRT) is suggested to be an effective treatment for children with autism spectrum disorder (ASD). Objectives: We aimed to compile evidence examining the effectiveness of PRT on social communication, social interaction, and repetitive behavior for children with ASD. Methods: We performed a systematic and…

School-based day treatment is an intensive mental health service for children with social, emotional, and behavioral difficulties. Research on day treatment is scarce and descriptions of program models are lacking. We used stimulated recall interviews to explore the moment-to-moment processes and strategies of classroom staff in a day treatment…

During a school day, children make several transitions between activities, which can take away from instructional time and result in challenging behaviors. This study investigates the impact positive engagement and behavioral supports have on children's behavior while transitioning. Participants (N = 40; 77.5% Male; 92.5% Hispanic) were enrolled…

Before adopting a scale for a new culture, researchers should conduct systematic translation procedures and evaluations to ensure its psychometric quality. The Pediatric Symptom Checklist-17 (PSC-17) is a brief and valid scale developed by U.S. researchers to evaluate children's emotional, attentional, and behavioral problems. This study aimed to…

Background: Adolescents' school engagement, mental health, and substance use have been major concerns during the COVID-19 pandemic, particularly given disruptions to school instruction. We examined how the instructional setting was associated with academic and health-related outcomes within an adolescent cohort followed during the pandemic.…
