This research investigated the capacity of the Minnesota Multiphasic Personality Inventory (MMPI) to differentiate multi-disabled persons who had become successfully rehabilitated from those who had not. It was expected that the overall MMPI profile of unsuccessful rehabilitants would reflect a greater degree of psychological maladjustment than would the MMPI profile of clients with successful rehabilitation outcomes. Demographic variables were also used to compare a group of successful rehabilitated clients with a group whose cases had been closed unemployed. The subjects were 131 clients who had attended the Minneapolis Rehabilitation Center during a two-year period and whose cases had been closed at least one year. Concerning the comparison of MMPI profiles of the unsuccessful and successful groups of clients, the results indicated that the two profile configurations were "similar." It was suggested that a more profitable research task might be the development of an MMPI profile code type strongly related to rehabilitation failure. (Author)
