The general objective of this study was to examine post-traumatic stress disorder among help-seeking torture survivors of Eritrean refugees at Mai Ayni and Adi Harush refugee camps. Accordingly, five specific objectives were established. These were 1) identify types of torture among help-seeking torture survivors 2) analyze the prevalence of PTSD symptom severity 3) examine the statistically significant difference between PTSD and demographic variables ( i.e. gender, age, and marital status ) 4) describe the distribution of behavioral functioning difficulties and 5) investigate the relationship between PTSD symptoms and behavioral functioning problems. To achieve these research objectives a cross-sectional survey design and quantitative approach were implemented. A sample of 516 torture survivor participants, 348 males and 168 females adolescent and adult clients were used from the clinical database of the Center for Victim of Trauma Ethiopia through population census. The measures for data collection were a checklists, post-traumatic stress diagnosis scale and behavioral functioning problem scale. The data were analyzed through independent sample t-test, one-way ANOVA, percentage, frequency, mean, standard deviation, and linear regression using SPSS version 25. Thus, the results of the present study revealed that: The participants were exposed to more than one types of torture and the majority of the respondents reported that 406(78.7%) they had been beaten and 232(45%) psychologically tortured. Regarding the severity of posttraumatic stress disorder, from the total 516 participants, 478(92.7%) had moderate to severe symptoms of post-traumatic stress disorder. There was a statistically significant difference in post-traumatic stress disorder symptom severity in gender in which female suffered more than male. However, there were no statistically significant differences in post-traumatic stress disorder symptom severity among the age and marital status categories. Majority of the participants had faced behavioral functioning problems in their daily living as a result of their traumatic experience. A moderate positive relationship between PTSD and behavioral and functional difficulty was found with 32 percent of the variance. Finally, based on the results of the present study recommendations were made to respective stakeholders.rnKeywords: Post-traumatic stress disorder, Torture survivor, help-seeking, and Eritrean refugees
