The purpose of this study is to examine the efficacy of cognitive processing therapy (CPT) in treating posttraumatic stress disorder (PTSD), depression and anxiety among Syrian refugees who have experienced war trauma. Clinicians interviewed 94 patients and asked them to complete the Clinician-Administered PTSD Scale three times: pretreatment, posttreatment and at the 12-month follow-up. In addition, PTSD, depression and anxiety were assessed using the PTSD Checklist, Beck Depression Inventory and Beck Anxiety Inventory at pretreatment, weekly, posttreatment and 12-month follow-up.
