Background: Self-injurious behaviour is frequently identified as part of the behavioural phenotype of Cornelia de Lange syndrome (CdLS). We conducted a case-control study of the prevalence and phenomenology of self-injurious behaviour (SIB) in CdLS. Methods: A total of 54 participants with CdLS were compared with 46 individuals who were comparable…

The aims of this study were to investigate the rates of deliberate self-harm (DSH) behavior among an Italian adolescent sample, as well as to explore its clinical correlates. On a sample of 234 adolescents in Italian secondary schools (Mean age = 16.47; SD = 1.7) were assessed the DSH as well as externalizing symptoms (including both conduct…

Background: Self-restraint is a pervasive phenomenon among individuals who engage in self-injurious behaviour (SIB). Materials and Methods: The present study examined the use of clothing as a socially acceptable alternative to self-restraint to reduce SIB and other topographies of self-restraint in an adolescent diagnosed with autism. Two separate…

The purpose of this study was to examine the relationship between childhood abuse, assault, cognitive distortion, and non-suicidal self-injury (NSSI) in a clinical adolescent sample. The sample included one hundred eighty-five psychiatrically hospitalized adolescents and their parents. Adolescent participants were predominantly female (71.4%),…

The article begins with a critical look at the existing literature explaining self-injury by people with significant learning disabilities and self-harm by those with mental health difficulties. It suggests that the different conceptualizations are perhaps less distinct than might initially appear, and that behavioural similarities between those…

While awareness of non-suicidal self-injury (NSSI) appears to be increasing among school counselors, social workers, nurses, and others who work with youth, it remains one of the most difficult behaviors to encounter, with few professionals feeling well equipped to handle these situations. This introductory article aims to define NSSI, describe…

Nonsuicidal self-injury (NSSI) is a prevalent behaviour among youth. School is an opportune setting for intervention with this population, but it is unknown how many youth who engage in NSSI would be willing to access school-based support. The current study surveyed 7,126 middle and high school students. Those that indicated that they engaged in…

Self-injury (SI) is defined as the act of deliberately destroying one's own body tissue without suicidal intent in a way that is not widely socially acceptable and is not as a result of mental retardation, autism, or other developmental delays. The review of the self-injury literature focused on the definition, prevalence, and other basic aspects…

Concern about the prevalence of nonsuicidal self-injury is widespread. Members of an electronic listserv for college counseling center directors nationwide were invited to participate in a Web survey to investigate provider experience with nonsuicidal self-injury; 290 surveys were analyzed. Most respondents perceived recent increases in…

The neurobiology of borderline personality disorder (BPD) remains unclear. Dysfunctions of several neurobiological systems, including serotoninergic, dopaminergic, and other neurotransmitter systems, have been discussed. Here we present a theory that alterations in the sensitivity of opioid receptors or the availability of endogenous opioids…

The present study builds on previous research, which demonstrated higher levels of depressive and interpersonal conflict language in first-person narrative accounts of nonsuicidal self-injury (NSSI) and suicide attempt (SA) in borderline personality disorder. The present study was designed to examine the semantic similarity of time-sequences…

This case study was conducted with a student diagnosed with autism and Tourette syndrome who displayed severe self-injurious behavior (SIB). We conducted a functional behavioral assessment which indicated that SIB was maintained by multiple functions using an ABAC design to determine the effect of positive social attention and extinction. Results…

As suicide attempts and self-injury remain predominant health risks among adolescents, it is increasingly important to be able to distinguish features of self-harming adolescents from those who are at risk for suicidal behaviors. The current study examined differences between groups of adolescents with varying levels of self-harmful behavior in a…

The researchers examined the effect of a classroom-based intervention on the frequency of aggression-related injuries occurring at an inclusive early education center. Aggression-related injuries involving five children decreased 79% following the intervention. Teachers implemented the procedures with fidelity. Treatment fidelity and child…

Participants were 101 individuals with self-injurious behavior (SIB) and severe or profound intellectual disability who were matched by gender, age, and level of intellectual disability to controls. Persons with SIB were more likely to exhibit the challenging behaviors of physical aggression, property destruction, sexually inappropriate behaviors…
