RecruitingBehavioural interventionSelf-Injury Treatment and Recovery in VeteransNonsuicidal 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.
