Prevalence and correlates of post-traumatic stress disorder among survivors of road traffic accidents in Ethiopia

BACKGROUND: Post-traumatic stress disorder is the most common mental disorders occurring among survivors of road traffic accident. However, research into post-traumatic stress disorder and correlates in low and middle-income countries is limited. To the best of our knowledge, there is no published study of the post-traumatic stress disorder and associated factors conducted in Ethiopia. Therefore, this study aimed to determine the prevalence of post-traumatic stress disorder and associated factors among survivors of road traffic accident. METHODS: Institution based cross-sectional study was conducted in May 2016. Data were collected using a pretested, structured, standardized post-traumatic stress disorder Checklist-Specific version (PCL-S) questionnaire. Systematic sampling technique was used to select the study participants. Binary logistic regression analysis was used to identify associated factors. Odds ratio with 95% CI was computed to assess the strength of associations. RESULTS: The prevalence of post-traumatic stress disorder was found to be 22.8% (CI 19.2, 26.6) among survivors of road traffic accident. In the multivariable analysis, Being female [AOR = 2.23, 95% CI 1.40, 3.56], having poor social support [AOR = 2.1, 95% CI 1.34, 3.46], duration since accident (1–3 months) [AOR = 1.72, 95% CI 1.07, 2.76] and having depression [AOR = 3.46, 95% CI 1.99, 5.99] were significantly associated with PTSD among survivors of road traffic accident. CONCLUSION: In the current study the magnitude of post-traumatic stress disorder was high. Being female, poor social support, duration since the accident (1–3 months) and depression were found to be significant predictors of post-traumatic stress disorders. The finding suggests a need for early screening for post-traumatic disorder among survivors of road traffic accidents.
