title: Changes in Millon Clinical Multiaxial Inventory scores among opiate addicts as a function of retention in methadone maintenance treatment and recent drug use.
abstract: The Millon Clinical Multiaxial Inventory (MCMI) was administered to 144 men and 86 women within 1 month of admission to methadone maintenance treatment and was readministered 18 months following admission. Based on prior research, we hypothesized there would be significant decreases on scales measuring affective disturbance, anxiety, and social isolation and little change in scales measuring antisocial and narcissistic traits. In addition, it was hypothesized that changes on the MCMI would be related to retention in treatment and illicit drug use during the interim between initial assessment and follow-up. Data were analyzed using a multivariate analysis of variance (MANOVA) for repeated measures. There was an overall decrease in MCMI scores, indicating less psychopathology between initial assessment and follow-up. MCMI scales did not change as a function of retention status, but decreases in MCMI scale scores were greater for subjects who were light drug users in the 6 months prior to the follow-up compared to heavy users. Inspection of individual MCMI scales supported our hypothesis; there were decreases on scales measuring affective disturbance, anxiety, and social isolation, but not on scales measuring antisocial and narcissistic traits.
