90 1st-time admitted alcoholics in an outpatient clinic completed the Millon Clinical Multiaxial Inventory-I (MCMI-I) as part of the initial evaluation. Many Ss had 1 of 2 personality disorders: the passive-aggressive (59.5%) or dependent personality disorder (56.8%). Alcohol abuse for more than 5 yrs was related to high scores on the following scales: anxiety, somatoform, hypomanic, drug abuse, and alcohol abuse. The alcohol abuse scale was the only one to show discriminant validity when compared with norms of the American standardization. High scores on the passive-aggressive scale predicted early dropout from treatment. 17.7% of respondents showed invalid MCMI scores, a finding correlated with comorbid intellectual impairment, concurrent treatment with benzodiazepines, length of time spent in completing the test, and length of time since abstinence.
