Abstract

BACKGROUND: Individuals identifying as a sexual minority report engaging in nonsuicidal self-injury (NSSI) at substantially higher rates compared to their heterosexual peers. Given that NSSI is a known risk factor for suicide, it is important to understand the processes unique to being a sexual minority that increases risk for NSSI so that adequate prevention efforts can be established. The current study integrated Minority Stress Theory and the Interpersonal Theory of Suicide to test a model of NSSI and suicide risk. METHODS: A total of 137 college students who identified as a sexual minority completed an anonymous on-line study assessing NSSI, suicidal thoughts/behaviors, and constructs of the minority stress and interpersonal theories. Two linear regressions using bootstrapping analyses were conducted to test our hypotheses. RESULTS: Minority stress was directly associated with NSSI and via perceived burdensomeness, explaining 27 % of the variance. NSSI was associated with increased risk for suicide thoughts/behaviors directly, and through acquired capability, explaining 45 % of the variance. CONCLUSIONS: These findings provide evidence that unique stressors individuals face as a result of their sexual minority status increases risk for self-harm by influencing cognitive and emotional processes such as burdensomeness and acquired capability. Implications for prevention, intervention, and future research are briefly discussed.
