Self-injurious behavior (SIB), such as self-biting and head banging, has been reported to occur in approximately 10% of captive, individually housed nonhuman primates. Accounts of the etiology of SIB in primates range from ecological to physiological. However, to date, no research has examined the possible influence of social consequences…

Background: Self-injurious behaviour (SIB) is among the most serious problems faced by intellectual disability services. It is very difficult to treat and can become a chronic problem. Method: Information on a number of variables was collected through a survey of service-users identified as displaying SIBs. Clinical opinion and a literature review…

Background: Self-injurious behaviour is commonly seen in Cornelia de Lange syndrome (CdLS). However, there has been limited research into the aetiology of self-injury in CdLS and whether environmental factors influence the behaviour. Methods: We observed the self-injury of 27 individuals with CdLS and 17 participants who did not have CdLS matched…

The assessment of maintaining variables with the goal of developing prosocial intervention plans has become a driving force in the intellectual disabilities (ID) literature. One particularly crucial variable is whether the behavior is low or high rate and whether the challenging behavior is best characterized by self-injury or aggression. Because…

Background: The diagnostic validity of autism spectrum disorder (ASD) based on Diagnostic and Statistical Manual of Mental Disorders (DSM) has been challenged in Down syndrome (DS), because of the high prevalence of cognitive impairments in this population. Therefore, we attempted to validate DSM-based diagnoses via an unbiased categorisation of…

In this study, we report on the development and psychometric evaluation of the Risk-Taking (RT) and Self-Harm (SH) Inventory for Adolescents (RTSHIA), a self-report measure designed to assess adolescent RT and SH in community and clinical settings. 651 young people from secondary schools in England ranging in age from 11.6 years to 18.7 years and…

Functional analyses of inappropriate mealtime behavior typically include conditions to determine if the contingent delivery of attention, tangible items, or escape reinforce food refusal. In the current investigation, descriptive analyses were conducted for 25 children who had been admitted to a program for the assessment and treatment of food…

Three participants whose problem behavior was maintained by contingent attention were exposed to 45-min presessions in which attention was withheld, provided on a fixed-time (FT) 15-s schedule, or provided on an FT 120-s schedule. Following each presession, participants were then tested in a 15-min session similar to the social attention condition…

Self-harm is widely recognized as a significant adolescent social problem, and recent research has begun to explore its etiology. Drawing from Agnew's (1992) social psychological strain theory of deviance, this study considers this issue by testing three hypotheses about the effects of traditional and cyber bullying victimization on deliberate…

Despite the clinical relevance of self-injurious thoughts and behaviors (SITB) among youth, little is known about the subset of youth most at-risk for SITB. This study examined the moderating roles of gender, racial/ethnic background, and school-level (and their interactions) on rates of SITB within a large (N = 2638, 52.2% female),…

A paucity of research exists examining personality and cognitive characteristics that may contribute to nonsuicidal self-injury (NSSI). The purpose of the current study was to clarify the contribution of perfectionism and rumination, along with depression and anxiety, to NSSI within a sample of 170 college students. Group comparisons revealed that…

The differences in factors associated with subgroups of adolescents in the continuum of deliberate self-harm (DSH) phenomena were investigated. In an anonymous self-report survey of 6,020 adolescents aged 15 and 16 years, 3.2% of adolescents (5.3% females, 1.3% males) reported DSH with intent to die, 2.8% (4.3% females; 1.5% males) reported DSH…

Children with autism frequently display self-injurious behavior (SIB), but skin picking--a less severe topography of SIB--has not been the focus of much clinical research. The present study evaluated a home-based intervention that was implemented with a 9-year-old girl who had autism and picked her fingers with resulting tissue damage. The…

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…

Self-injurious behavior (SIB) that occurs at high rates across all conditions of a functional analysis can suggest automatic or multiple functions. In the current study, we conducted a functional analysis for 1 individual with SIB. Results indicated that SIB was, at least in part, maintained by automatic reinforcement. Further analyses using…
