Assessment of posttraumatic stress disorder in Cambodian refugees using the Clinician-Administered PTSD Scale: Psychometric properties and symptom severity



Posttraumatic stress disorder (PTSD) symptoms were assessed by using the Clinician-Administered PTSD Scale (CAPS) in a consecutive sample of Cambodian refugees attending a psychiatric clinic in the United States. Psychometric properties of the translated CAPS and severity of PTSD-related symptoms were examined. The CAPS demonstrated adequate psychometric properties, including coefficient alpha (.92) and item–total correlations (.48–.85). Of the sample 56% (101/179) met Diagnostic and Statistical Manual of Mental Disorders, fourth edition, criteria for current PTSD. Those patients who met criteria for current PTSD had significantly higher CAPS total scores (M = 65.3, SD = 18.1) than those who did not meet the criteria (M = 13.9, SD = 16.7).
