Modification of CAPS-1 for diagnosis of PTSD in Afghan refugees

Abstract

A DSM-III-R based instrument for the assessment of posttraumatic stress disorder (PTSD), the Clinician-Administered PTSD Scale (CAPS-1), was modified to accommodate cultural differences and translated into the Afghan languages Pushto and Farsi (Dari) and administered to 30 Afghan refugees living in the United States. The modified CAPS-1 was found to be practical and reliable. Inter-item correlations were calculated on the frequency and intensity scores for the 17 cardinal symptoms and the eight associated features items of the modified CAPS-1. The four reexperiencing items demonstrated significant independence from the avoidance and arousal symptom clusters. However, the avoidance and arousal symptom clusters were not found to be independent cardinal components of PTSD in our participants. The CAPS-1 criteria for diagnosis of PTSD were met by 50% of the subjects evaluated.
