Objectives: To explore the salience of pre- and postmigration stresses as risk factors for posttraumatic stress disorder (PTSD) and to identify resilience factors and explore their mental health salience.
Methods: We conducted a mental health survey of 1603 Sri Lankan Tamils in Toronto, incorporating the World Health Organization Composite International Diagnostic Interview for PTSD.
Results: According to the International Classification of Diseases, 10th Revision, criteria, lifetime prevalence for PTSD was 12%; according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria it was 5.8%. Female sex and the number of stresses of passage increased the probability of PTSD, whereas satisfaction with life and the availability of nonfamily social relations reduced it.
Conclusions: Consideration of pre- and postmigration stresses of passage and of the nature of resilience contributes to an improved understanding of PTSD among refugees.
