This study investigated if Rohingya refugeepeople resettled in camps in rural Bangladesh and urban locations in Malaysia had different levels of trauma, mental health and everyday functioning. The study also examined if direct and indirect exposure to traumatic events could predict PTSD, depression, generalized anxiety, and everyday functioning in the two groups separately. An attempt was also made to see if the relations between trauma and mental health were different across the two settings. This was a cross-sectional study, for which we conveniently recruited 100 adult Rohingyas, 50 from each country; the majority was males. Rohingyas in Bangladesh fled Myanmar's Rakhine State following a major military crackdown in 2017, whereas Rohingyas in Malaysia fled Rakhine gradually over the last three decades because of recurrent violence and military operations. We assessed trauma (cumulative trauma, direct trauma, and indirect trauma), PTSD, depression, generalized anxiety, and everyday functioning of the participants using traumatic event questionnaire, PTSD-8, PHQ-9, GAD-7, and WHODAS-2.0. The Bangladeshi cohort experienced more types of traumatic events (i.e., cumulative trauma) than did the Malaysian cohort (d = 0.58). Although the two cohorts did not differ in terms of indirect exposure to traumatic incidents (i.e., indirect trauma), the Malaysian cohort had direct exposure to traumatic events (i.e., direct trauma) more frequently than did the Bangladeshi cohort (d = 1.22). The Bangladeshi cohort showed higher PTSD (d = 1.67), depression (d = 0.81), generalized anxiety (d = 1.49), and functional impairment (d = 2.51) than those in Malaysia. Hierarchical linear regression analyses showed that after controlling for demographic variables, both direct and indirect trauma significantly predicted PTSD, depression, and functional impairment among Rohingyas in Bangladesh, with direct trauma being the stronger predictor. However, similar analyses showed that only indirect trauma predicted PTSD among Rohingyas in Malaysia, while all other effects were nonsignificant. The results also showed that the predictive relationship between direct trauma and PTSD was different across the two countries. With the same level of direct trauma, a participant from Malaysia would score 0.256 points lower in PTSD than a participant from Bangladesh. The recently experienced direct and indirect trauma have impaired mental health and everyday functioning among the Bangladeshi cohort. However, only indirect trauma was active to cause PTSD in the Malaysian cohort as direct trauma was weakening due to the time elapsed since migration. We discuss the results in the context of the current theories of trauma and mental health and suggest therapeutic interventions for the refugee population.
