Characteristics of women with alcohol use disorders who benefit from intensive motivational interviewing

Abstract

Background Women with alcohol disorders have more severe problems related to their drinking than men. They have higher mortality from alcohol-related accidents and enter treatment with more serious medical, psychiatric, and social consequences. Objective: This study assessed the effects of Intensive Motivational Interviewing (IMI), a new, 9-session counseling intervention for women with drinking problems. Methods: A randomized clinical trial was conducted with 215 women. Most were white (83%), college educated (61%), and older (mean age 51). Half received IMI and half a standard single session of MI (SMI) along with an attention control (nutritional education). Results: Generalized estimating equations models showed women who were heavy drinkers at baseline in the IMI condition reduced heavy drinking more than those in the SMI condition at 2-, 6-, and 12-month follow-up. Analyses of disaggregated subgroups showed IMI was most effective for women with low psychiatric severity, more severe physical and impulse control consequences associated with drinking, and higher motivation. However, formal 3-way interaction models (condition by moderator by time) showed significant effects primarily at 2 months. Conclusions: Improvements associated with IMI were limited to heavy drinking and varied among subgroups of women. Studies of women with more diverse characteristics are needed.
