A Brief Intervention to Reduce Nonsuicidal Self-Injury and Improve Functioning in Veterans

Nonsuicidal self-injury (NSSI) refers to the intentional destruction of one's own body tissue without suicidal intent and for purposes that are not socially sanctioned. While NSSI has been understudied among Veterans, the lifetime prevalence rate of NSSI in Veterans is approximately three times higher than the general population. Moreover, NSSI is associated with increased risk for violence, psychiatric distress, and marked impairment in psychosocial functioning. Even though NSSI is distinct from suicidal behaviors in several important ways, NSSI remains a strong predictor of a future suicide attempt. The primary goal of this project is to evaluate the treatment and acceptability of a brief intervention for NSSI that aims to reduce psychosocial impairment and NSSI behaviors in Veterans. This treatment, known as the Treatment for Self-Injurious Behaviors (T-SIB) incorporates evidence-based approaches to replace NSSI with behaviors that improve psychoso ial functioning. A core component of T-SIB is functional assessment that identifies the antecedents and consequences of NSSI. This project will enhance T-SIB by using ecological momentary assessment (EMA) to conduct NSSI functional assessment in-vivo. EMA reduces retrospective recall bias and can increase engagement with therapeutic goals.
