Background: Aggressive behaviour (AB) and non-suicidal self-injury (NSSI) are common in people with mild intellectual disability or borderline intellectual functioning, leading to adverse consequences for themselves and those around them. Method: We investigated the relationship between AB (both total and physical in particular) and NSSI and risk…

This study tests General Strain Theory (GST) as an explanation for associations between adverse childhood experiences (ACEs) and risk of violent and suicidal behaviors. Data comprise a census of archival information about the lives of 2,195 delinquent boys who resided at a U.S. treatment facility between 1975 and 2019. Logistic regression tests…

Objective: The present study explored differences in four domains of university adjustment (i.e. personal-emotional, social, academic, and institutional attachment) among students with and without a history of engaging in non-suicidal self-injury (NSSI) and examined the independent influence of NSSI on university adjustment. Participants and…

During the immediate period following psychiatric hospitalization, adolescents are at increased risk for suicide attempts and rehospitalization. Because most adolescents return to school during this time, school-related experiences are important considerations during the transition from inpatient hospitalization. This study sought to understand…

Drawing on the Health Adversity Risk Model, this study examines the relationship between mental health and sexual risk behaviors in British and European Union (EU) university students in the United Kingdom. Four hundred and thirty-one undergraduate students completed a cross-sectional survey. Data were analyzed using independent samples t-tests,…

Background: Non-suicidal self-injury (NSSI) is a serious and relatively prevalent problem in adolescence. Although several studies have identified risk factors for the aetiology and maintenance of NSSI, little is known about the impact of individual and contextual variables in such pervasive behaviors among adolescents. Objective: This paper aims…

Objective: This study seeks to evaluate the psychometric properties of the Ottawa Self-Injury Inventory-Functions (OSI-F) for assessing nonsuicidal self-injury (NSSI), a condition for further study in the DSM-5. Participants: Participants included 345 students who indicated a history of self-injury in a university counseling center over six…

Individuals with intellectual disability (ID) show high rates of challenging behavior (CB). The aim of this retrospective study was to assess the factors underlying CB in an adult, clinical ID sample (n = 203). Low levels of emotional development (ED), as measured by the "Scheme of Appraisal of ED," predicted overall CB, specifically…

A total of thirty-two women admitted to a general hospital for medical treatment after self-harming completed measures of conventional positive and negative masculinity and femininity. Comparisons were made with two control groups with no self-harm history; 33 women receiving psychiatric outpatient treatment and a nonclinical sample of 206 women.…

Research suggests that adolescents' engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time, yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal studies are presented to examine whether NSSI may be associated with peer influence…

This longitudinal population-based study examined pathways to nonsuicidal self-harm (NSSH) in relation to childhood sexual abuse (CSA), assault victimization in early adulthood, posttraumatic stress disorder symptomatology (PTSD), and other mental disorders. At age 21, 476 men and 455 women completed interviews on assault victimization, PTSD, and…

Few studies have investigated the extent to which psychosocial/psychological factors are associated with the prediction of deliberate self-harm (DSH) among adolescents. In this study, 737 pupils aged 15-16 years completed a lifestyle and coping survey at time one and 500 were followed up six months later. Six point two percent of the respondents…

A community survey in 4,426 adults was undertaken as part of the World Mental Health Survey Initiative reporting the prevalence and risk factors for suicide-related outcomes in Colombia. Lifetime prevalence estimates of suicide ideation, plans, attempts, and risk factors for suicide-related outcomes were assessed. Retrospective reports of…

Research has identified a significant increase in both the incidence and prevalence of non-suicidal self-injury (NSSI). The present study sought to test both linear and non-linear cusp catastrophe models by using aversive self-awareness, which was operationalized as a composite of aversive self-relevant affect and cognitions, and dissociation as…

Remarkably little is known regarding the temporal course of adolescent suicidal ideation and behavior, the prediction of suicidal attempts from changes in suicidal ideation, or the prediction of suicidal attempts after accounting for suicidal ideation as a predictor. A sample of 143 adolescents 12-15 years old was assessed during psychiatric…
