This study examined patterns of consistency and change on the basic personality and symptom scales of the Millon Clinical Multiaxial Inventory (MCMI) in a sample of VA inpatient alcoholics (N = 96), who were administered the MCMI at intake and at 1 month into treatment, and in a sample of drug abusers (N = 33), who received MCMI administrations at intake into treatment and after 1 and 3 months of treatment. Both alcohol and drug abuser samples in this study showed significant changes on most personality and symptom scales between intake and 1 month into treatment. The drug abusers showed small, but significant changes on three personality scales between 1 and 3 months of treatment. No such changes on symptom scales were apparent in this analysis.
