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…

However, self-compassion and wellness behaviors may protect against risk. The relation between self-compassion and suicidal behavior and the contributing roles of…

Purpose: To evaluate the claim, made repeatedly during "Diagnostic and Statistical Manual of Mental Disorders", Fifth Edition debates over eliminating the bereavement exclusion (BE), that ''uncomplicated'' depressive reactions have elevated suicidality like other major depressive disorder (MDD), so exclusions risk…

Self-harming and suicide amongst adolescents are reported to be increasing in Europe and internationally. For young people in state care, this aspect of mental well-being is of particular concern. The aim of this study was to establish the incidence of suicidal ideation and behaviour amongst young people (age 16-21 years) leaving state care in one…

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: The link between aggression and mental disorders has been the focus of diverse studies in persons with and without intellectual disabilities (ID). Because of discrepancies in the finding of studies in persons with ID to date, and because of differences in research design, instruments used and the population studied, more research is…

The aim of the study was to ascertain suicide seasonality in the Greek population and to associate this seasonal variation with age, sex, and suicide method. Studying seasonality can be of help in establishing a public health policy, related with suicide prevention. This is an epidemiologic study based on forensic evidence. We studied the deaths…

The epidemiology of a neglected form of suicidal behavior, Russian roulette, is addressed. Also tested is an explanation of racial differences based on the opportunity theory of deviant behavior related to the availability of revolvers, necessary weapons with which to play Russian roulette. Data refer to 15 cases of Russian roulette found through…

This study examined predictors of psychiatric hospitalization among children with autism spectrum disorders (ASD). Data were collected from 760 caregivers of children with ASD.
