Background: Adults with intellectual disability (ID) are at high risk of exhibiting challenging behaviors, especially those with autism spectrum disorder (ASD). There are clinical and transdiagnostic variables that are largely related to the existence of these behaviors, and it is necessary to know the particularities of their role in people with…

This study aims to contribute to the knowledge about lacking or contradictory effects of benzodiazepine on hyperaroused or aggressive behaviour in persons with intellectual disability (ID). We conducted a retrospective and natural case study in a person with mild ID and multiple adverse childhood experiences (ACE), using routine diary data…

Introduction: Social knowledge is an important aspect of social cognition that pertains to broader knowledge of social concepts and norms. People with intellectual disabilities are more likely to experience mental health challenges, and it's important to pay special attention to how comorbid conditions can affect their social cognition skills,…

Research suggests that children suffering from different types of disorders (learning disorders, behavioral disorders, or intellectual disabilities) are sometimes evaluated differently simply due to the presence of a diagnostic label. We conducted a multilevel meta-analysis of experimental studies (based on data from 8,295 participants and on 284…

Background: Studies about teams of staff supporting people with intellectual disability have focused on team performance of existing teams. This study aimed to examine important factors in the process of setting up a new team of support staff. Specifically, we considered the process for a team that supports service users with mild intellectual…

Parents of children with ASD who had attended an Australian emergency department (ED; n = 421) completed a questionnaire relating to their experiences in the ED, including (1) child's reason for presentation and existing comorbidities, (2) quality of care during the visit (3) child's behaviour during visit, e.g. sensory responses to the ED…

The United States (U.S.) Department of Education reports that the range for all students with disabilities included for at least 80% of the day in the general education classroom in different states is between 83.6% and 36.9%. Such a range also exists for individual disability groups. While other studies have noted these differences, none have…

Disruptive behavior disorders and social skills were assessed in 187 youth aged 13 years, with typical cognitive development (TD n = 98), intellectual disability (ID n = 37), autism spectrum disorder (ASD, IQ > = 85, n = 26), or Autism Spectrum Disorder with ID (ASD/ID; IQ < 85, n = 26). The primary question was whether youth with ASD and…

Introduction: Youth with intellectual disabilities (ID) demonstrate higher rates of disruptive behavior disorders (DBDs) than youth with typical development (TD). DBDs such as oppositional defiant disorder (ODD) predict higher rates of delinquency during adolescence. Yet, few studies have examined risk-taking and delinquency among youth with ID.…

Introduction: Features of intellectual disability (ID) and/or autism spectrum disorder (ASD) may hinder responsiveness to interventions typically used during psychiatric hospitalization to manage severely disruptive behavior, and could increase the likelihood of experiencing restraint and/or seclusion (R/S). This study investigated the occurrence…

Elementary music specialists teach all students in all grades at their schools, which requires the preparation of a variety of lessons simultaneously. As a result of seeing 100% of the student population, elementary music teachers host more students with disabilities than a general classroom teacher would in their class. Depending on the severity…

Background and purpose: The purpose of this study was to assess the level of mental disorders and challenging behaviour in individuals with intellectual disability (ID) supported by specialized services, but without a prior psychiatric diagnosis, and to compare the levels of different disorders depending on the severity of ID. Methods: This is a…

The aim of this study was to investigate the psychiatric disorders that accompany mild intellectual disability (ID) in school-aged children in a clinical setting. The Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version interview was conducted with the children with mild ID and their…

Disruptive behavior disorders were assessed in 160 youth aged 13 years, with Autism Spectrum Disorder (ASD, n = 48), intellectual disability (ID, n = 28), or typical development (TD, n = 84). Mothers' reported collateral effects on their psychological adjustment were related to both youth disability status and clinical level behavior disorders.…

Background: The theoretical understanding of firesetting behaviour has predominantly been developed with men in prisons or psychiatric hospitals without neurodevelopmental disabilities. Consequently, there is a lack of evidence regarding the validity of current theory when applied to adults with intellectual disabilities and/or autism. Method:…
