The most commonly used interview for posttraumatic stress disorder (PTSD) is the Clinician-Administered PTSD Scale (CAPS), a semi-structured interview patterned after the DSM-IV criteria (Blake et al., 1990). The Computerized PTSD Scale – Multimedia Version (CPS-M: Richard, Mayo, Bohn, Haynes, & Kolman, 1997) is a computerized interview that is modeled after the CAPS. This study examined how well the CPS-M agreed with the CAPS diagnostically in a clinical sample. Ninety veterans completed the test protocol consisting of paper-and-pencil measures, the CPS-M, and the CAPS interview. Correlations between the CAPS and CPS-M were high at the item, subscale, and full-scale levels. Confidence interval analysis revealed that the CPS-M scales were not significantly different from their CAPS counterparts but failed to establish equivalence. Alpha scores for the scales indicated good internal consistency on both the CAPS and CPS-M. Difference scores between the two instruments were normally distributed, and scale effect sizes were negligible. ROC curve analysis for the CPS-M revealed high diagnostic accuracy. These results present a strong case for more widespread use of the CPS-M in the assessment of PTSD.
