Testing whether the combination of victimization and minority stressors exacerbate PTSD risks in a diverse community sample of sexual minority women.
Informed by minority stress and intersectionality frameworks, we examined: 1) associations of sexual identity and race/ethnicity with probable diagnosis of post-traumatic stress disorder (PTSD-PD) among sexual minority women (SMW; e.g., lesbian, bisexual); and 2) potential additive and interactive associations of minority stressors (discrimination, stigma consciousness, and internalized homonegativity) and potentially traumatic childhood and adulthood events (PTEs) with PTSD-PD. Data come from a large and diverse community sample of SMW (N = 662; age range: 18-82; M = 40.0, SD = 14.0). The sample included 35.8% Black, 23.4% Latinx, and 37.2% White participants. Logistic regressions tested associations of sexual identity and race/ethnicity, minority stressors, and PTEs with PTSD-PD. More than one-third of SMW (37.2%) had PTSD-PD with significantly higher prevalence among bisexual, particularly White bisexual women, than lesbian women. Discrimination, stigma consciousness, and internalized homonegativity were each associated with higher odds of PTSD-PD, but only internalized homonegativity was additively associated with PTSD-PD in mutually adjusted models above and beyond effects of PTEs. No evidence for interactive effects between PTEs and minority stressors was found. In a diverse community sample of sexual minority women, PTSD is strongly associated with potentially traumatic childhood events and with minority stressors above and beyond the associations with other potentially traumatic events and stressors in adulthood. Our findings suggest a strong need for therapists to address the effects of stigma and homophobia in treatment for PTSD, as these minority stressors likely maintain and exacerbate the effects of past traumas.
