Operational definitions have a significant history in applied behavior analysis. The practice's importance stems from the role operational definitions play in detecting an event, human thought, or action. While operationalizing target behaviors has enjoyed widespread practice, some concerns have recently arisen with translation validity and…

Objective: There is a lack of research examining factors that promote the disclosure of nonsuicidal self-injury (NSSI) among post-secondary students. However, elucidating which factors facilitate disclosures among students -- particularly students with high risk NSSI -- is important given that disclosure may facilitate access to care. Methods:…

Non-suicidal self-injury (NSSI) is a significant public health concern, with severely impacts for adolescent mental health. As awareness of the harmful effects of NSSI grows, there is an increasing emphasis on understanding the underlying mechanisms in this age group. This study explores how internalizing and externalizing issues related to…

Non-suicidal self-injury (NSSI) is a significant mental health concern on university campuses. It has been proposed that dispositional mindfulness, which may be fostered through mindfulness practice, may have important benefits for university students with a history of NSSI through its positive impact on coping self-efficacy. However, students'…

Autistic people experience a higher prevalence of self-harming behaviours than do the general population. Self-harm remains a stigmatised topic, and until recently, self-harming behaviours in autism were considered to be limited to self-injurious behaviours experienced by intellectually impaired autistic children and not to be experienced by…

Objectives: Non-suicidal self-injury (NSSI) risk in young adults is impacted by both affective and cognitive responses to stress. While previous research shows affective reactivity (AR) increases risk for NSSI, less research has examined the role of cognitive reactivity (CR). The current study examined how individual differences in CR to stress…

Background: Historically, the research and treatment of self-injury has been disciplinarily siloed. As a result, the behaviour is understood and treated differently among individuals with and without intellectual and developmental disabilities. We explore the potential for an interdisciplinary research and practice agenda in self-injury. Method:…

Introduction: There is evidence of a gap between individuals with intellectual and developmental disabilities (IDD) who need treatment for self-injurious behavior (SIB) and those who receive treatment. The purpose of this study (n = 15) was to begin to understand the treatment gap from the perspective of family caregivers. Methods: In…

Objective: We examined whether meaningful subgroups of self-injurious behaviors (SIBs) would emerge within a pool of first-year college students already deemed at elevated risk. Participants: First-year undergraduates (N = 1,068) recruited in 2015-2018 Fall terms. Methods: Past-year nonsuicidal self-injury (NSSI) frequency, past-year number of…

Previous research suggests that nonsuicidal self-injury (NSSI; the intentional destruction of bodily tissue without suicidal intent) occurs among elementary-aged children. However, it remains unclear to what extent elementary school educators encounter NSSI among students and how they respond. Therefore, this study investigated cross-national…

Objective: Adolescents and young adults are at risk for non-suicidal self-injury (NSSI) and suicidal behavior. This study examined intrapersonal (depressive symptoms, self-criticism) and family (perceived family functioning, parenting style, parental attachment) factors associated with reported history of NSSI in a college sample. Method:…
