Trauma exposure and PTSD prevalence among Yazidi, Christian and Muslim asylum seekers and refugees displaced to Iraqi Kurdistan.

100% prevalence of trauma exposure and 48.7% of current PTSD among refugees, 70% PTSD rate of Yazidi participants, which is significantly higher (p < 0.01) compared to 44% of Muslim participants and 32% of Christian participants. These findings were corroborated using the self-rated PTSD, DSM-5 Checklist, with more severe PTSD symptom scores (p < 0.001) obtained among Yazidis (43.1; 19.7), compared to Muslims (31.3; 20.1) and Christians (29.3; 17.8). Self-rated depressive symptoms (Patient Health Questionnaire-9) were also higher (p < 0.007) among Yazidis (12.3; 8.2) and Muslims (11.7; 5.9), compared to Christians (8.1; 7).
