Use of the MMPI in predicting completion and evaluating changes in a long-term alcoholism treatment program.

Abstract

Veterans admitted to a 90-day alcoholism treatment program were administered the MMPI, and those who completed the program were retested before discharge. Completers differed significantly from noncompleters on the Pd scale. Although responses on most MMPI scales indicated improvement after treatment, those on the MacAndrew Alcoholism Scale were not affected. Neither the MacAndrew nor the Unitary Alcoholism Factor differentiated between completers and noncompleters.
