MMPI PROFILES IN PTSD AS A FUNCTION OF COMORBIDITY

A sample of 135 Vietnam veteran inpatients with combat-related PTSD wa s sorted into three groups, depending upon the presence of concurrent psychiatric disorders: Depression (n = 68), Psychosis (n = 31), and Ot her (n = 36). Pairwise comparisons were made on the MMPI with respect to the validity indicators, clinical scales, four relevant Harris-Ling oes subscales, the Psychoticism content scale, and the MMPI-PTSD subsc ale. Results indicate variations in scale elevations as a function of comorbid diagnosis. Various items and scales appear to differentiate t he Psychosis group due to greater psychopathology. In general, the res ults spotlight the heterogeneous aspects that comorbidity brings to PT SD assessment.
