Individuals with lesbian, gay, and bisexual (LGB) identities have higher prevalence of self-directed violence, but very little is known about racial/ethnic differences between LGB populations. This study aimed to examine racial/ethnic differences in self-harm, suicidal ideation, suicide attempt, and depression among LGB and heterosexual emerging adults. Data are compiled from the Fall 2008 and Spring 2009 National College Health Assessment and limited to respondents within emerging adulthood (ages 18–24) who indicated their sexual orientation and racial/ethnic identities (n = 89,199). Within each racial/ethnic group, LGB individuals were significantly more likely to report self-harm, suicidal ideation, suicide attempt, and depression than non-LGB individuals.
