Background: Longitudinal research is needed to strengthen evidence for risk factors for challenging behaviour in children with intellectual disabilities and to understand patterns of change over time. Methods: Data on challenging behaviour were collected for 225 students in one school over four annual time points and a range of potential risk…

The benefits of mindfulness have been noticed in academics, but whether and how perceived mindful parenting prevents maladaptive academic behaviours (e.g. rigid persistence, self-handicapping, and compulsive learning behaviour) have rarely been discussed. Therefore, a model of perceived mindful parenting, insecure attachment, children mindfulness,…

This study aimed at analyzing the differences in challenging behaviors between adults with intellectual disability and ASD and those who only had intellectual disability, as well as to explore associations between transdiagnostic and clinical variables to these differences. Therapists and educators of 163 adults with intellectual disability (83…

Autism spectrum disorder (ASD) is an etiologically heterogeneous neurodevelopmental condition that eludes a single explanation or cure. Epidemiological studies reveal risk factors, relevant comorbidities, and behavioral correlates to reach a better understanding of ASD. To contribute such data from an understudied ASD population, this paper…

Restricted or repetitive behavior (RRB) is common for individuals with visual impairment (VI), autism spectrum disorder (ASD), and intellectual disability. Previous reviews have suggested that VI may moderate the effectiveness of behavioral interventions to decrease RRB. A search of the single case literature resulted in 30 studies and 40…

The relationship between emotion regulation, social interaction and different types of restricted and repetitive behaviors is poorly understood. In the present study, structural equation modeling based on information about 239 individuals with autism was used to examine whether emotion regulation and social communication were associated with…

To effectively prevent and address self-harm behavior (SHB), it is crucial to understand the relational and social contexts of young people (YP) who engage in SHB, as well as the meanings they ascribe to their behavior. The aim of study is to gain a deeper understanding of the processes SHB among YP in disadvantaged neighborhoods in Turkey. The…

The aim of this study is to use Q methodology to explore how school staff experience the behaviours of children with Smith-Magenis Syndrome (SMS) in school and how they manage working with these children. Q methodology utilises by-person factor analysis to investigate subjectivity. Fourteen school staff of students with SMS in Norway participated…

Physical and mechanical restraints and seclusion are currently used as emergency procedures in public schools across the United States. Students who exhibit dangerous, aggressive, or self-injurious behaviors are more likely to be restrained or secluded in school. Since many students with autism spectrum disorder exhibit one or more of these…

It was not known what school staff identifies as student behavioral concerns in rural, low-income elementary schools, what they attribute as the cause of these behaviors, and how this attribution may affect their response to such behavior. This qualitative case study explored the experiences of school staff members at a low-income elementary…

Cornelia de Lange syndrome (CdLS) is associated with repetitive and self-injurious behaviors (RBs, SIB). Evaluating children with CdLS, this study: (1) characterizes the spectrum of RBs; (2) characterizes the impact and severity of RBs including SIB; (3) describes how age and adaptive functioning relate to RBs including SIB. Fifty children…

Background: Mental health is a priority for high schools, but extant programs often focus on symptom reduction rather than promoting adolescents' developmental assets. Objective: The goal of this study is to examine whether Art in Mind (AIM), a strengths-based after-school organized art activity tailored to fit the needs of adolescents with…

Restricted interests and repetitive behaviors (RRBs) are core symptoms of autism spectrum disorder (ASD), and commonly occur in attention-deficit/hyperactivity disorder (ADHD). Little is known about how RRBs manifest in ADHD. We quantified and compared factor structures of RRBs in children with ASD (n = 634) or ADHD (n = 448), and related factors…

Self-injurious behaviors (SIB) are elevated in autism spectrum disorder (ASD) and related genetic disorders, but the genetic and biological mechanisms that contribute to SIB in ASD are poorly understood. This study examined rates and predictors of SIB in 112 individuals with disruptive mutations to ASD-risk genes. Current SIB were reported in 30%…

Elevated salivary cortisol levels have been documented in individuals who engage in self-injurious behavior (SIB), indicating acute physiological stress. Less is known about the chronicity of stress and SIB. We analyzed the relationship between parent ratings of problem behavior and hair cortisol concentrations (an index of chronic adrenocortical…
