Skin picking is highly prevalent in people with Prader-Willi syndrome (PWS). This study addressed the temporal (frequency, duration) and wider characteristics (e.g. type of skin picked, apparent motivations, or management strategies) of skin picking to inform intervention strategies. Nineteen parents/carers who observe skin picking shown by the…

A systematic literature review was undertaken to ascertain the prevalence of self-harm and suicidal behaviour in children and young people under 18 years old with a diagnosis of autism spectrum disorder (ASD), with or without an intellectual disability. There was variation in the reported prevalence rates but results suggested that rates of both…

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…

Self-injurious behaviour is purportedly common in autism, but prevalence rates have not yet been synthesised meta-analytically. In the present study, data from 14,379 participants in thirty-seven papers were analysed to generate a pooled prevalence estimate of self-injury in autism of 42% (confidence intervals 0.38-0.47). Hand-hitting topography…

Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

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…

Crucial to understanding an individual, presenting with intellectual disability and the management of their challenging behaviours, is the knowledge of the types of those specific behaviours. The term aggressive behaviour is a universal term that embraces many aspects of behaviour that vary in terms of severity, frequency and seriousness for the…

Several reports suggest children with autism spectrum disorder (ASD) are more likely to be seen for injury-related ED visits; however, no nationally representative study has examined this question. Using data from the 2008 Nationwide Emergency Department Sample, over a quarter of all visits among those with ASD were related to injury. In the…
