Prejudice-Related Events and Traumatic Stress Among Heterosexuals and Lesbians, Gay Men and Bisexuals.

This mixed-methods study examined associations between prejudice events and posttraumatic stress disorder (PTSD) among 382 lesbians, gays, and bisexuals (LGB) and 126 heterosexuals. Using the Composite International Diagnostic Interview, we assessed PTSD but relaxed Criterion A1, that is, allowed prejudice events that did not involve threat to life or physical integrity to also qualify as traumatic. First, we tested whether exposure to prejudice events differed with respect to sexual orientation and race. White LGBs were more likely than White heterosexuals to encounter a prejudice event, but Black and Latino LGBs were no more likely than White LGBs to experience a prejudice event. Second, we used qualitative analysis to examine the prejudice events that precipitated relaxed Criterion A1 PTSD among 8 participants. Two specific themes emerged: the need to make major changes and compromised sense of safety and security following exposure to the prejudice event.
