MCMI characteristics of DSM-III posttraumatic stress disorder in Vietnam veterans

Compared the MCMI profiles of 25 veterans with a diagnosis of Posttraumatic Stress Disorder (PTSD) with those of 25 veterans carrying psychiatric disorders which typically cause problems in the differential diagnosis of PTSD. The PTSD group had higher elevations on nine of the 20 MCMI scales (all ps less than .05). Profiles were also significantly different in shape and scatter. A discriminant analysis accounted for 100% of the variance and correctly classified 88% of the patients. Resulting MCMI profiles appear to be consistent with DSM-III criteria for PTSD.
