Abstract
BackgroundMechanisms worsening the development of Posttraumatic stress disorder (PTSD) symptoms among individuals affected by high-mortality epidemics are unclear. This study examined the prevalence of PTSD and related risk factors among populations affected by the Ebola virus disease (EVD) outbreak, and investigated whether peritraumatic distress mediates the impact of exposure level to EVD on PTSD symptoms, and the moderation role of stigmatization. MethodsThe sample included 1614 participants (50% women) affected by EVD in Democratic Republic of the Congo (DRC). Participants completed the PTSD Check-List for DSM-5, Peritraumatic Distress Inventory, and measures evaluating levels of exposure and stigmatization related to EVD. Descriptive analyses and a moderated mediation model were computed. ResultsA total of 58.81% participants (95% CI: 56.41%; 61.21%) met PTSD diagnostic criteria. Participants living in rural areas presented greater risk, while there is no significant difference between men and women. Peritraumatic distress mediated partially the association between exposure to EVD and PTSD symptoms. Moreover, this relationship was moderated by stigmatization related to EVD. LimitationsAs the design was cross-sectional, this study could not examine the causality of PTSD symptoms among communities affected by EVD. ConclusionsThis study shows high prevalence rates and important risk factors associated with PTSD in populations affected by EVD. It indicates elements that could help to develop and implement prevention and intervention programs in affected communities.
