The validity and clinical utility of post-traumatic stress disorder in Afghanistan.

This study examined the validity and utility of PTSD among 320 adults in Afghanistan. Findings support the validity of PTSD in this cultural context: PTSD symptoms were highly prevalent, shared common variance, and correlated as expected with exposure to traumatic stress. However, only limited support was found for the clinical utility of PTSD. Other types of psychiatric symptomatology, including depression and a culturally specific measure of general distress, correlated more highly with traumatic stress than did PTSD; and PTSD accounted for limited variance in functioning beyond that explained by depression and general distress. Implications for research and intervention are considered.
