Abstract

Objectives: The purpose of this study was to examine associations between psychotherapy session attendance, alcohol treatment outcomes, and Alcoholics Anonymous (AA) attendance. Method: Using data from Project MATCH, repeated measures latent class analyses of psychotherapy session attendance were conducted among participants in the outpatient arm who were randomly assigned to complete 12-session cognitive-behavioral therapy (CBT; n = 301), 12-session twelve-step facilitation (TSF; n = 335), or 4-session motivational enhancement therapy (MET; n = 316). Associations between psychotherapy attendance classes, heavy drinking, alcohol-related consequences, psychosocial functioning, and AA attendance were examined at posttreatment (97% retention), 1-year posttreatment (92% retention), and 3-years posttreatment (85% retention). Results: In general, participants who attended all 12 CBT/TSF sessions had significantly fewer heavy drinking days and alcohol-related consequences at all posttreatment time points than participants who attended 0–2 CBT/TSF sessions. Participants who attended all four MET sessions generally had significantly fewer heavy drinking days and alcohol-related consequences at posttreatment and 1-year posttreatment than participants who attended 0–1 MET sessions. Participants who attended more TSF and MET sessions generally attended more AA meetings, and participants who attended less CBT sessions generally attended fewer AA meetings. Conclusions: With some exceptions, attending all sessions in CBT, TSF, and MET was related to the most favorable heavy drinking and alcoholrelated consequences outcomes. Alcoholics’ Anonymous and other mutual help groups may be attended differently based on the form and dose of psychotherapy
