Background: Suicidality in individuals with intellectual disability is a critical but under-researched area. This systematic review aims to synthesize existing literature on the prevalence, risk factors, and interventions for suicidality among individuals with intellectual disability. Methods: Adhering to the PRISMA guidelines, a comprehensive…

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…

We analyzed the Healthcare Cost and Utilization State Emergency Department (ED) Databases and State Inpatient Databases for all individuals who were 2 years of age or older with at least one ED visit from 2011 to 2016 in New York to estimate the association between suicide and non-fatal injury-related ED visits and autism spectrum disorder (ASD).…

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…

Research suggests that the incidents of self-harm among young people are increasing and age of onset of self-harm is decreasing. There is limited understanding of how widespread the problem of self-harm among younger school students is, and how schools respond to these incidents. This study used an in-depth qualitative approach to understand…

This study builds on existing literature on autism spectrum disorder (autism) and sexual and gender minority (SGM) identities and is the first to examine self-declared frequency rates, associated functional impairments, and treatment engagement levels for sexual minority (SM) and non-SM populations with and without autism cross-sectionally via a…

Background: Clinical data indicate that the rates of non-suicidal self-harm (SH) are rising and developing younger, causing increasing concern. However, to date, no United Kingdom (UK), Irish or European community based surveys have been able to determine the prevalence rates of not only "SH ideation" but also "actual incidences of…

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%…

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-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those "without" intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n =…

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…

Among college students in the United States nationally, non-suicidal self-injurious (NSSI) behaviors have become alarmingly and increasingly common. Among those willing to disclose, recent estimates indicate 25-30% engaged in NSSI in 2020 alone. Prevalence is significantly elevated among students who identify as a sexual minority (i.e., lesbian,…

School staff have a unique opportunity to detect and respond to mental health issues including self-harm and suicidal behaviour in adolescents. There is limited knowledge about how these incidents are managed in schools. This study aims to understand the incidence rates, perceived severity and management of self-harm and suicidal behaviour…

Prevalence studies of challenging behaviors among children with disabilities have a potential value, as they provide information for intervention and evaluation. However, the results from these studies seem to vary according to the population involved, the behaviors explored and the selected methodological procedures and instruments used. The…
