Is Trauma Exposure More Harmful for Sexual Minority Youth? Differences in Trauma-Suicide Associations in a Nationally Representative Sample of U.S. Youth and Implications for Suicide Prevention.

Purpose: Lesbian, gay, and bisexual (LGB) youth experience disproportionately high rates of suicidality and exposure to traumatic events, such as sexual violence and teen dating violence. Rates of suicidality and exposure to traumatic events also vary by sexual minority subgroup. The purpose of this study was to: (1) explore the impact of LGB identity on the relationship between violence exposure and suicide; and (2) to examine variations by sexual identity. Method: A subsample of respondents who reported on their sexual identity in the Youth Risk Behavior Survey (n = 14,690) was used to examine if the associations between sexual and dating violence with suicide outcomes (suicidal ideation, planning, and suicide attempt) depended on the sexual identity of the respondent. Logistic regression models were fitted with an interaction effect to quantify heterogeneity of associations across identity strata. Results: Overall interaction tests mostly indicated heterogeneity of associations between sexual violence and physical dating violence. Several contrast of strata associations suggested substantive probability differences between sexual minority respondents and their heterosexual peers. Conclusion: While exposure to violence was broadly associated with increased probability of experiencing any type of suicidality, LGB and questioning youth were significantly more likely to experience suicidality compared to their heterosexual peers. Gay and lesbian youth demonstrated the strongest probability of experiencing suicidal thoughts and behaviors among survivors of sexual violence, while bisexual youth may be more at risk following dating violence. Implications for future research and suicide prevention are discussed.
