Abstrakt:	Objective: Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) frequently co-occur, with elevated rates of both disorders in lesbian, gay, or bisexual (LGB) samples. Few studies have compared the strength of PTSD-AUD associations between LGB and heterosexual individuals or evaluated the role of nontraumatic LGB discrimination in these relationships among sexual minorities. Method: The current study utilized nationally representative epidemiological data ( N = 29,646) to (a) examine whether associations between lifetime trauma endorsement/PTSD and lifetime alcohol dependence (AD) differ as a function of sexual minority status and (b) evaluate the role of LGB-specific discrimination in trauma/PTSD and AD associations among LGB individuals. Results: Logistic regression analyses showed the association between lifetime trauma endorsement and lifetime AD was significantly greater in magnitude for LGB individuals (odds ratio [ OR ] = 2.17) compared to heterosexual individuals ( OR = 1.32; Z = 2.51, p < .05). The magnitude of the association between lifetime PTSD and lifetime AD was not greater in the LGB subsample ( OR = 2.11) than the heterosexual subsample ( OR = 1.71; Z = 0.63, p > .05), after controlling for trauma endorsement. Among the LGB subsample, logistic regression analyses did not support a significant main effect for LGB discrimination nor an interaction between trauma endorsement and nontraumatic LGB discrimination, nor between PTSD and nontraumatic LGB discrimination, on lifetime AD ( p s > .05). Conclusions: LGB individuals demonstrate stronger associations between lifetime trauma endorsement and AD, relative to heterosexual counterparts; however, this association may not be accounted for or moderated by nontraumatic LGB discrimination.
