Introduction: Challenging behaviors are common in individuals with developmental disabilities and pose significant challenges to their well-being and that of their families and communities. Method: We explored the occurrence and predictors of self-injurious behavior and aggressive/destructive behavior in 372 Canadian youths (aged 4-20 years) with…

Background: The aim was to investigate the aggressive behavior of young people in specialized institutions with intellectual disability (ID) with or without autism spectrum disorder (ASD). Method: Data on 305 institutionalized young people were collected using two aggression scales, the 'Children's Scale of Hostility and Aggression:…

Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized…

A percentage of individuals with autism and other developmental disabilities engage in severe, dangerous challenging behaviors. Two common approaches for intervening for these behaviors are function-based interventions (FBI), which have been effective at reducing such behaviors, and crisis intervention, which has been shown to increase staff…

This study aimed at identifying the extents of abuse of autistic children and some behavioural disorders in who were abused and who were not abused from parents and teachers' perspective. To achieve the study's objectives, the researcher adopted a descriptive research method and used a survey as a tool for the task. The sample consisted of 200…

Previous research is not conclusive in detailing the prevalence of challenging behaviour and its correlates in children with intellectual disabilities in school settings in particular. In the current study, an amended version of the Behaviour Problems Inventory -- Short Form was used to collect data from a sample of 321 students in a special…

To date, the phenotypic significance of EEG abnormalities in patients with ASD is unclear. In a population affected by ASD we aimed to evaluate: the phenotypic characteristics; the prevalence of EEG abnormalities; the potential correlations between EEG abnormalities and behavioral and cognitive variables. Sixty-nine patients with ASD underwent…

Introduction: Current research findings in the field of intellectual disabilities (ID) regarding the relationship between mental health problems and challenging behavior are inconclusive and/or contradictory. The aim of this study was to further investigate the putative association between these two highly prevalent phenomena in people with ID,…

Aggression, self-injurious behavior, and severe tantrums are impairing symptoms frequently experienced by individuals with autism spectrum disorders. Despite US Food and Drug Administration approval of two atypical antipsychotics targeting these symptoms in youth with autistic disorder, they remain frequently drug refractory. We define…

The type, frequency and inter-relationships of emotional and behavioural problems in 863 children with autism spectrum disorder (ASD) were investigated using the population-based Database of children with ASD living in the North East of England (Daslne). A high rate of problems was reported, with 53% of children having 4 or more types of problems…

This "2018-2019 Interagency Autism Coordinating Committee (IACC) Strategic Plan Update" is the work of the IACC membership that was appointed under the Autism CARES Act of 2014. The Committee agreed that the "2016-2017 IACC Strategic Plan" reflected a comprehensive review of the state of the field and provided a set of 23 new…

Background: It is well established that very few individuals with autism spectrum disorders (ASD) and an IQ below 70 are able to live independently as adults. However, even amongst children with an IQ in the normal range, outcome is very variable. Childhood factors that predict later stability, improvement or decline in cognitive functioning…

The present study was a multisite randomized clinical trial assessing the effects of adding a cognitive-behavioral intervention to positive behavior support (PBS). Fifty-four families who met the criteria of (a) having a child with a developmental disability, (b) whose child displayed serious challenging behavior (e.g., aggression, self-injury,…

Children with autism and autism spectrum disorders have a high rate of irritability and aggressive symptoms. In one study up to 20% of children with autism have symptoms of irritability and aggression including aggression, severe tantrums, and deliberate self injurious behavior (Lecavalier [2006] "J. Autism Dev. Disord." 36:1101-1114.). These…

Children and youth with autism spectrum disorders (ASD) or emotional and behavioral disabilities (E/BD) often exhibit challenging behavior including aggression, self-injury, non-compliance, or property destruction (Kamps, Kravits, Rauch, Kamps, & Chung, 2000; National Autism Center, 2009). As a result, students with ASD or E/BD often miss out…
