Diagnosing Posttraumatic Stress Disorder in Refugees
Global crises has amounted to the forced international displacement of 25.4 million refugees. Refugees from conflict-affected areas are especially vulnerable to posttraumatic stress disorder (PTSD) compared to the general population due to their past and present hardships and history of trauma. PTSD is characterized by a constellation of symptoms identified by the Diagnostic and Statistical Manual of Mental Disorders (DSM). DSM-5 departed from DSM-IV by reclassifying PTSD as a trauma- and stressor-related disorder and introducing a fourth symptom cluster—negative alterations in mood/cognition—to the previous three-symptom cluster model. In severely traumatized refugees, this new cluster exhibited relatively high sensitivity, specificity, positive predictive power, and negative predictive power—in concordance with the range of symptoms exhibited by this population—and allowed for the applicability of the DSM-5 criteria. However, the Western sample basis of the DSM-5 might make it inferior to alternative models as a diagnostic tool for PTSD in refugees and as a springboard for treatment. In addition (and possibly due) to PTSD, refugees are at high risk for mental health distress and suffer from poor health outcomes. Optimizing diagnostic criteria and overcoming barriers to diagnosis and access to care would benefit patients and facilitate treatment.
