Al-Anon Intensive Referral to facilitate concerned others' participation in Al-Anon Family Groups: a randomized controlled trial.

Abstract

To test the effectiveness of an intervention, Al-Anon Intensive Referral (AIR), to facilitate participation in Al-Anon Family Groups (Al-Anon). Multi-site, randomized controlled trial of AIR versus usual care (UC), with follow-up assessments at 3, 6 and 12 months. The 12-month follow-up rate was 74%. Residential alcohol use disorder (AUD) treatment programs in three US locations. Concerned others (COs) of patients in treatment for AUD. COs were mainly women (77%) who were patients' spouses (33%) or parents (25%). AIR (n = 128) consisted of four sessions over 3 months with an Al-Anon coach. UC (n = 151) was the treatment program's offer of educational sessions for COs. Primary outcome: COs' self-reports of any Al-Anon attendance (yes or no) at 3 months. number of Al-Anon meetings and the CO-patient relationship (stressors, resources). Potential predictors of outcomes examined in generalized linear mixed models were their baseline value, time, CO-patient relationship type (marital or non-marital), treatment program and condition. There was no effect of condition for the primary outcome (28% in AIR, 21% in UC; Bayes factor = 1.86). Relationship stressors at follow-ups were more severe for COs in a marital relationship with the patient than for COs in a non-marital relationship [β = 2.19, 95% confidence interval (CI) = 1.07, 3.32]. For CO-patient relationship resources at follow-ups, the main effect for condition was significant (β = 1.33, 95% CI = 0.04, 2.61). COs assigned to the AIR condition had more resources than COs who were in the UC condition. Relative to usual care, Al-Anon Intensive Referral was not associated with increases in participation of concerned others in Al-Anon, but was associated with more resources in the concerned other-patient relationship.
