MMPI evaluation of 5-year methadone treatment status.

Evaluated treatment outcome over a 5-yr period for 148 1st admissions (mean age, 27.14 yrs) to a methadone treatment program. Eleven Ss (7%) were successful treatment completions, 16 Ss (11%) transferred to other methadone programs, 38 Ss (26%) remained in continuous treatment, and 83 Ss (56%) were unsuccessful treatment terminations. Discriminant analysis using the MMPI suggested that the more stable Ss at admission had the best treatment outcome. For the patients in continuous treatment, MMPIs administered at 6-wk, 6-mo, and 5-yr intervals indicated that this group of Ss did not change on the personality dimension.
