Cognitive models of PTSD implicate attention to threat, negative social cognition, and behavioral avoidance in perpetuating symptoms. In contrast, moral elevation and gratitude are positive socio-moral emotions theorized to facilitate attention to positive features of one's social context and prosocial approach behavior. No research has examined the relevance of positive moral emotions in the well-being of sex-trafficked women, who may be prone to PTSD symptoms and low positive socio-moral emotions. I tested trait gratitude, elevation, and moral purity as predictors of well-being and moderators of PTSD symptoms on well-being. Participants included sex-trafficked (n = 16) and college (n = 50) women. PTSD diagnosis and symptom severity were determined using the ADIS-5 and PCL-5. Congruent with previous studies, higher PTSD symptoms predicted lower well-being in both samples. As predicted, the trafficked sample had higher prevalence of PTSD, higher PTSD symptom scores, higher negative emotion, and lower well-being than the college sample, and marginally lower trait gratitude. Unexpectedly, the trafficked sample demonstrated significantly higher moral purity than the college sample. Gratitude predicted well-being in the overall ( b = 2.57, SE = .48, p < .00) and control (b = 3.04, SE = .35, p < .00) samples but not in the sex-trafficked sample ( b = 1.56, SE = 1.37, p = .28), while moral elevation predicted well-being in all samples. Moral elevation buffered effects of PTSD in overall (b = .05, SE = .03, p = .05) and sex-trafficked (b = .09, SE = .05, p = .09) samples, while moral purity buffered effects of PTSD in the college sample (b = .73, SE = .33, p = .03). Additionally, I interviewed the sex-trafficked women about what they are thankful for, what inspires them, and what makes them feel morally clean or unclean, which provided a more nuanced, qualitative level of understanding these women's experiences. This research provides a preliminary investigation of not only the trauma-related symptoms of sex-trafficked women, but also their positive moral emotions which may serve a protective role and may ultimately contribute to their resilience.
