Validation of PTSD measures for older combat veterans.

This study evaluated three nosologically similar older groups (Older PTSD, POW, and Older Psychiatric) and a group of Younger PTSD veterans from Vietnam. Group membership was derived from index admission diagnoses and clinical validation of status. Groups were compared on the MMPI, PTSD measures, background variables, health measures and an outcome measure. Results showed that the Older PTSD group is closer to the Younger PTSD group than to the other groups on the MMPI and PTSD measures and also that members of this group remain in the hospital longer than do members of the other older groups. Parameters of effective test classification showed the PTSD measures to be helpful in correct identification of this disorder for the older groups.
