Motivational interviewing (MI) for the treatment of alcohol and drug problems is typically conducted over 1 to 3 sessions. This paper reports on an evaluation of an intensive 9-session version of MI (IMI) compared to a standard single MI session (SMI). Although no differences between IMI and SMI were found for methamphetamine use, there was an unexpected finding that women but not men with co-occurring alcohol problems in the IMI condition reduced the severity of their alcohol problems significantly more than those in the SMI condition at 4- and 6-month follow-up. Stronger perceived alliance with the therapist was associated with better outcome. Findings indicate that alcohol outcomes for women might be improved with the addition of more MI sessions. A current study is assessing the impact of IMI for women with more serious alcohol problems. Qualitative interviews are being conducted with women to better understand how IMI is helpful and why it appears to add benefit for women but not men.
