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…

Nonsuicidal self-injury (NSSI) refers to deliberately harming one's body without the intention of dying. Common methods include skin cutting, scratching, burning, and self-battery. NSSI is currently not listed as a diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), but it is considered a condition for further…

Issues regarding the diagnosis and treatment of non-suicidal self-injury (NSSI) continue to be of increasing concern to practitioners in educational and mental health settings. Given this rising concern, it is important to note that the majority of research regarding self-injury has focused on the symptomology and treatment of Caucasian females;…

Guided by the interpersonal theory of suicide, this study examines the associations between gun carrying, bullying, and suicidal behaviors among high school students. Arizona Youth Risk Behavior Surveys were completed by 2,677 students in 2011; 9.0% reported suicide attempt in the past year, 5.5% carried a gun in the past 30 days, 8.5% were…

This study examined characteristics and biopsychosocial predictors of nonsuicidal self-injury in a sample (N = 753) of youth in residential care admitted between 2005 and 2010. To model the data, the authors used t-tests, chi-square tests, and multiple logistic regressions stratified by gender. Results suggested that 12% of youth engaged in…

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 Center for Collegiate Mental Health (CCMH) 2021 Annual Report describes 153,233 unique college students, nationally and internationally, seeking mental health treatment; 4,043 clinicians; and more than 1,135,520 appointments from the 2020-2021 academic year. This is the 13th year the report has been produced. This year's report specifically…

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…

Objective: To describe basic nonsuicidal self-injury (NSSI) characteristics and to explore sex differences. Methods: A random sample from 8 universities were invited to participate in a Web-based survey in 2006-2007; 38.9% (n = 14,372) participated. Analysis assessed sex differences in NSSI prevalence, practices, severity, perceived dependency,…

In this article we summarize what is known about nonsuicidal self-injury (NSSI) in youth. First, we describe basic demographic trends, prevalence, and function. Then we turn our attention to the implications of NSSI for schools, school-related policies, and school guidelines. Having provided an overview of the field, we conclude that even in the…

The prevalence and risk factors associated with self-mutilation among opioid dependent cases and controls were determined, and the co-occurrence of self-mutilation and attempted suicide was examined. The prevalence of self-mutilation among cases and controls did not differ significantly (25% vs. 23%, respectively), with gender differences…

This project explored the prevalence of self-harm by cutting in a geographically circumscribed area of the North of England, using a school-based survey. Twenty-three per cent of the young people reported they had cut themselves at least once, with no major changes evident at different age groups or with gender. There were clear differences in…

We used National Fragile X Survey data in order to examine reported self-injurious behavior (SIB) to (a) generate lifetime and point prevalence estimates, (b) document detailed features of SIB (frequency, types, location, severity) in relation to gender, and (c) compare comorbid conditions between matched pairs (SIB vs. no SIB). Results indicate…

The predictive effects of peer victimization and harsh parenting on deliberate self-harm were examined. As derived from the experiential avoidance model, the study also tested whether these links were moderated by individual self-regulation approaches. Data were collected at two points in time from 880 junior high school students (mean age =…

The current study evaluated risk factors for the occurrence, frequency and severity of challenging behavior among a sample of individuals with a diagnosis of autism, under the age of eighteen, in Ireland. Age, gender, hours of intervention received, age at diagnosis, presence of challenging behavior at diagnosis and treatment type at diagnosis…
