Abstract

INTRODUCTION: People who identify as sexual minorities are at increased risk for suicide. Non-suicidal self-injury (NSSI) is also a risk factor for suicide and NSSI severity may contribute to development of capability for lethal self-injury. Further research is needed to understand how NSSI severity increases suicide risk, specifically in high-risk populations like sexual minorities. The current study seeks to examine whether sexual minority adults exhibit greater NSSI severity and suicide risk than heterosexuals, and if NSSI severity moderates the relationship between sexual orientation and suicide risk.

METHODS: Undergraduate students (N = 1,994) who reported five or more acts of NSSI in their lifetime completed online self-report questionnaires including sexual orientation, NSSI severity, and suicide risk.

RESULTS: A factorial ANOVA demonstrated main effects of sexual orientation and NSSI severity on suicide risk.

DISCUSSION: The lack of significant interaction effect indicates NSSI severity does not amplify the effect of on sexual orientation on suicide risk; rather, it predicts the same level of increased risk across orientations. Therefore, suicidality related to both sexual orientation and NSSI severity are equally important treatment targets.
