[Posttraumatic stress disorder in refugees and therapeutic interventions based on cognitive behavioral approach: A systematic review].

Post-Traumatic Stress Disorder (PTSD) is connected with the experience of traumatic events and is significantly related to war and forced displacement. Refugee populations are characterized by a high degree of vulnerability for the development of PTSD, as they are confronted with stressors associated with all three distinct phases of migratory journey. The present article is an attempt to systematic review the therapeutic interventions based on the Cognitive Behavioral Approach and applied to refugees diagnosed with PTSD. For this reason, a review of the international literature was carried out through the electronic databases: Google Scholar, PubMed and Science Direct. Forty (40) studies were identified, of which 16 met the inclusion criteria. According to the results of the review, the most common interventions are Cognitive Behavioral Therapy (CBT), Narrative Exposure Therapy (NET) and Eye Movement Desensitization and Readaptation (EMDR). More specifically, CBT helps the individual to understand and reexamine the negative thoughts and feelings caused by the traumatic event, resulting in a reduction of symptoms and an improvement in quality of life. Following, NET supports that when a person talks about the traumatic events by placing them in a chronological continuity, they can gradually redefine the negative associations and responses related with the trauma. Finally, EMDR focuses on memory and how memories are stored in the brain. Its purpose is to reduce the intensity of the emotions associated with the traumatic event when it is recalled. All of those three approaches appear to have been studied and to yield reliable results. Other forms of therapeutic interventions are limited due to methodological issues as well as due to adopting standardized approaches that do not allow for an in depth understanding of trauma in refugee population. Further investigation of the long-term symptoms of trauma in refugees is suggested, in order to draw firm conclusions.
