The current review presents a meta-analysis of the existing empirical literature on the prevalence of non-suicidal self-injury (NSSI) among lesbian, gay, bisexual, and transgender (LGBT) individuals, as well as on correlates of NSSI within sexual and gender minority populations. Eligible publications (n = 51) were identified through a systematic search of PsycINFO, MEDLINE, and Embase, supplemented by a search of references of prior reviews on this topic. NSSI prevalence rates were quite elevated among sexual (29.68% lifetime) and gender (46.65% lifetime) minority individuals compared to heterosexual and/or cisgender peers (14.57% lifetime), with transgender (46.65% lifetime) and bisexual (41.47% lifetime) individuals being at greatest risk. Even among these group findings, sexual minority youth emerged as an especially vulnerable population. Moreover, current evidence suggests these rates and differences between LGBT and heterosexual and/or cisgender peers have not declined over time. These findings may in some measure be due to the existence of LGBT-specific risk correlates combined with general risk correlates being more severe among sexual and gender minority populations. Additional research, particularly employing a longitudinal design, is needed in this area to advance efforts to reduce risk for NSSI among sexual and gender minority individuals.
