Phenylketonuria (PKU) is a rare, but serious, metabolic disease that can cause a variety of neurological, psychological, and academic complications. Fortunately, many individuals with PKU who are identified and treated early can go on to live a relatively normal life. However, PKU does continue to present with a variety of complex underlying…

In this study, we examined trajectories of specific domains of behavior problems (i.e., attention problems, depression/anxiety, and aggressive behavior) from age 6 to 18 in a sample of 55 children with fragile X syndrome. We also examined autism status and early parenting as predictors of subsequent behavioral trajectories. We found that attention…

Emotional and behavioral problems (EBPs), such as anxiety, overactivity, and aggression, can influence the diagnosis of autism spectrum disorder (ASD). The gold standard diagnostic tool for ASD, the "Autism Diagnostic Observation Schedule--Second Edition," includes three items ("E-codes") for EBPs that are frequently associated…

Emotion dysregulation is a common social functioning deficit in children with attention-deficit/hyperactivity disorder (ADHD). Little is known about how teachers rate irritability in school-aged children with ADHD. We examined irritability and disruptive behaviour in clinic-referred school-aged children (n = 145) with ADHD. Children in this…

Purpose: To compare functioning and environmental aspects before and during physical distancing (DPD) and to determine which social, physical, behavioral and functioning aspects of DPD are correlated. Methods: Sixteen parents of children/adolescents with Down syndrome (11.38 ± 3.00 years) were surveyed before and DPD. Paired t-tests were used to…

Autistic students often experience peer relationship difficulties. As peer acceptance and rejection may be malleable over time, we examined predictors of change in peer acceptance and peer rejection among early elementary-age autistic students. We followed 166 autistic children (mean age: 6.1 years [range: 4-8], 82.5% boys, grades preK-2nd)…

During the epidemic, the routines of all families and their children have changed. This situation adversely affected the lives of both families with normally developing…

Background: Bullying has a profound and enduring impact on academic achievement. However, there is a lack of clarity surrounding the specific mechanisms of this relationship. Aims: This study examined the link between bullying at age 9 and Numeracy/Literacy achievement at age 15 to determine if this relationship is partially or fully explained by…

The mental health and well-being of students entering higher education has become a growing global concern for colleges and universities. Recent research shows anxiety and depression to be the most prevalent forms of mental health concerns amongst college students followed by suicide, eating disorders, and substance abuse. Students' feelings of…

Teachers contribute to the process of identifying and referring students for mental health services, however, relatively little is known about how they make those decisions and how decision-making differs across school contexts. This study used a vignette-based method to investigate individual and school contextual factors associated with the…

Autistic students often experience peer relationship difficulties. As peer acceptance and rejection may be malleable over time, we examined predictors of change in peer acceptance and peer rejection among early elementary-age autistic students. We followed 166 autistic children (mean age: 6.1 years [range: 4-8], 82.5% boys, grades preK-2nd)…

This practice brief provides practical, research-based strategies educators can use to de-escalate challenging student behavior in the classroom. Despite the development of supportive, safe, and predictable school environments, students may, at times, become agitated, and their behavior may escalate to unsafe levels. With some advance planning,…

The present study examined whether parental involvement within the framework of the parent-teacher relationship as established through Conjoint Behavior Consultation (CBC) enhances the academic achievement of students diagnosed with High Functioning Autism Spectrum Disorder (HFASD). Due to the COVID 19 pandemic, this study began with the…

Many early childhood programs are not prepared to meet the needs of children who have significant social, emotional, and behavioral challenges. "Program-Wide Supports for Pyramid Model Implementation" (PWS-PMI) provides a systematic approach to supporting early childhood programs using Pyramid Model practices and enhancing children's…

Children with Developmental Delay (DD) and Autism Spectrum Disorder (ASD) experience challenging behaviors, including noncompliance, that impact individual and family functioning across settings. Due to developmental risk, parenting has emerged as being especially instrumental within this population, with positive parenting practices directly…
