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).…

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…

Self-injury is common in autism spectrum disorder (ASD); however few studies have investigated correlates of self-injury or the putative associations with self-restraint. Questionnaire data on self-injury, self-restraint, health conditions, overactivity/impulsivity and repetitive/restricted behavior were collected on 208 children and 216 adults…

Research has suggested that individuals who engage in self-injurious behavior may have enhanced expressions of pain, which contradicts previous assertions of blunted pain sensitivity in this population. The purpose of this study was to measure expressions of pain among young children being evaluated for autism and other neurodevelopmental…

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…

The aim of this study was to analyse statistically published data regarding the age related prevalence of aggression and self-injury in persons with intellectual disability. Studies including prevalence data for aggression and/or self-injury broken down by age band were identified and relative risk analyses conducted to generate indices of age…

Nonsuicidal self-injury (NSSI) among adolescents is a growing concern. However, little is known about gender and features of this behavior. Gender differences in NSSI among a sample of 7,126 adolescents were investigated, 1,774 of whom reported having engaged in NSSI. Gender differences in prevalence, method, and location of NSSI were examined.…

The present study investigates the association of parenting and family factors with nonsuicidal self-injury (NSSI) in preadolescents. A sample of 1,439 preadolescents and their parents were assessed by means of (a) adolescent-reported parenting behaviors (support and behavioral/psychological control), (b) parent-reported parenting behaviors…

Aggression is a clinically significant problem for many children and adolescents with autism spectrum disorders (ASD). However, there have been few large-scale studies addressing this issue. The current study examined the prevalence and correlates of physical aggression in a sample of 1584 children and adolescents with ASD enrolled in the Autism…

Background: Few studies have examined deliberate self-harm (DSH) among children in residential treatment in Canada. Most of the existing studies examined adolescent students or children from pediatric emergency departments. Objectives: The objectives of this study were to examine the prevalence of DSH among children in tertiary care residential…

This study reports the prevalence of self-injurious behavior and suicide attempts among college students in Indonesia and examines risk factors distinguishing between 3 groups: self-injury with suicide attempt, non-suicidal self-injury, and non-self-injury. Self-report questionnaires measuring self-injury and suicide attempts, negative mood…

Objective: This study explores prevalence and characteristics associated with supervisory neglect and physical harm in children in the child welfare system in Canada. Methods: The sample included all substantiated primary maltreatment investigations in the 2008 Canadian Incidence Study of Reported Child Abuse and Neglect excluding cases where…

Background: Self-injurious behaviour (SIB) is a devastating problem observed in individuals with various neurodevelopmental disorders, including specific genetic syndromes as well as idiopathic intellectual and developmental disability. Although an increased prevalence of SIB has been documented in specific genetic mutations, little is known about…

Background: Autism spectrum disorder (ASD) has been identified as a risk marker for self-injurious behaviour. In this study we aimed to describe the prevalence, topography and correlates of self-injury in individuals with ASD in contrast to individuals with Fragile X and Down syndromes and examine person characteristics associated with self-injury…
