OBJECTIVE: This study aimed to inform clinical practice by identifying subgroups of patient-concerned other (CO) dyads. Patients with alcohol use disorders (AUDs) were characterized on Alcoholics Anonymous (AA) involvement and substance use together with COs'' Al-Anon involvement. Predictors and recovery maintenance outcomes of subgroup membership were examined. METHOD: Participants were 279 patient-CO dyads. Patients were in residential treatment for AUD. Parallel latent class growth model analysis characterized 12-step involvement and substance use at treatment entry and 3-, 6-, and 12-month follow-ups. RESULTS: Three classes were as follows: 38% Low AA/Low Al-Anon (patients'' low AA and COs'' low Al-Anon involvement, and patients'' high-to-moderate substance use), 10% High AA/High Al-Anon (patients'' high AA and COs'' high Al-Anon involvement, and patients'' moderate-to-low substance use), and 52% High AA/Low Al-Anon (patients'' high AA and COs'' low Al-Anon involvement, and patients'' moderate-to-low substance use). At follow-up, the Low AA/Low Al-Anon classes'' patients were less likely to have spirituality as recovery support, confidence about staying abstinent, and satisfaction with recovery progress. The High AA classes'' COs had less concern about patients'' drinking and scored higher on positive aspects of relationships with patients. CONCLUSIONS: Clinicians should encourage patients'' and COs'' 12-step group involvement (12-step practices'' engagement). Among patients treated for AUD, AA involvement was related to better outcomes, and to COs'' lessened concern about the patients'' drinking. COs'' Al-Anon involvement was associated with having a more positive view of their relationship with the patient. That more than one third of dyads had low 12-step group involvement suggests that treatment programs may need to facilitate involvement in non-12-step mutual-help groups.
