DEVELOPMENT AND VALIDATION OF THE COMPUTERIZED CLINICIAN ADMINISTEREDPOSTTRAUMATIC-STRESS-DISORDER SCALE-1-REVISED

A computer administered version of the clinician administered post-tra umatic stress disorder (PTSD) scale-1 was developed to assess PTSD in subjects presenting with psychological symptoms following exposure to a traumatic event. Both forms were administered to 40 subjects who met the Diagnostic and Statistical Manual, third edition, revised (DSM-II I-R) criteria for exposure to a significantly traumatic stressor. Inte r-observer reliability was demonstrated with a kappa statistic of 0.90 . The computer version had a sensitivity of 0.95 and a specificity 0.9 5. A correlation of 0.95 was found between the two versions and the me an score difference was nonsignificant. The computer form demonstrated adequate internal reliability and test-retest reliability. Overall re sults suggest the computer version is a valid and reliable measure of PTSD.
