Magnitude and factors associated with post-traumatic stress disorder among war-affected internally displaced people in northwest Ethiopia, 2022

Abstract

Background: A large number of people are often directly involved in armed conflict and, therefore, are at greater risk of developing a wide range of mental disorders, including post-traumatic stress disorder. Despite this, few have been reported about it in low- and middle-income countries, including Ethiopia. Objective: This study was carried out to assess the magnitude and factors associated with post-traumatic stress disorder among war-affected internally displaced people in northwest Ethiopia, 2022. Methods: Cross-sectional study design was conducted from May 23 to June 22, 2022, and simple random sampling was used to select a sample of 412 participants. Data were collected by structured interviewer-administered questionnaires. The post-traumatic stress disorder checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition with extended criteria-A was used to assess post-traumatic stress disorder. Multivariable logistic regression analysis was done to identify factors associated with post-traumatic stress disorder. Results: A total of 412 participants were interviewed with the response rate of 100%. The mean age of the respondents was 34.7 (±10.9) years. The prevalence of post-traumatic stress disorder was found to be 60.98% (95% CI: 56.1%, 65.5%) with an estimated prevalence of 23.5% and 76.5% among males and females, respectively. In multivariable analysis, female sex (AOR = 2.39; 95% CI: 1.48, 3.86), having depression (AOR = 2.86; 95% CI: 1.78, 4.60), family history of mental illness (AOR = 3.67; 95% CI: 1.43, 9.42), and poor social support (AOR = 3.61; 95% CI: 1.74, 7.47) were factors significantly associated with post-traumatic stress disorder at p-value < 0.05. Conclusion and recommendation: Based on this study, at least 6 out of 10 war-affected populations have experienced post-traumatic stress disorder. Especially females, those who had depression, family history of mental illness, and poor social support, were more vulnerable to post-traumatic stress disorder. Therefore, it is recommended to do on-site screening and provide treatment for all displaced populations suffering from post-traumatic stress disorder by giving special concern for females, individuals having depression, poor social support, and family history of mental illness.
