Posttraumatic stress disorder correlates among internally displaced Yazidi population following Islamic state of Iraq and Syria attacks in Iraq

Background In 2014, the so-called Islamic State of Iraq and Syria (ISIS) took over one-third of Iraq. This study measured the rate of posttraumatic stress disorder (PTSD) among Iraqi Yazidi internally displaced persons (IDPs) and examined associated demographic and traumatic risk factors. Methods A cross-sectional survey was carried out in April–June 2015 at the Khanke camp, northern Iraq. Trauma exposure and PTSD were measured by the Harvard Trauma Questionnaire (Iraqi version). Results Of 814 adult Yazidi IDPs, 34% screened positive for PTSD. Avoidance and intrusion symptoms had the highest means (M = 3.16, SD = 0.86 and M = 2.63, SD = 0.59 respectively). Associated factors of PTSD included exposure to a high number of traumatic events, unmet basic needs and having witnessed the destruction of residential or religious areas (OR = 1.39, 95% CI: 1.02–1.9 and OR = 1.25, 95% CI: 1.01–1.53 respectively). Being a widow was the only linked demographic factor (OR = 15.39, 95% CI: 3.02–78.39). Conclusions High traumatic exposure, specifically unmet basic needs and having witnessed destruction, was an important predictor of PTSD among Yazidi IDPs. These findings are important for mental health planning for IDPs in camps.
