Effects of 12-step mutual support and professional outpatient services on short-term substance use outcomes among adults who received inpatient treatment.

BACKGROUND

Continuing care is increasingly prioritized in the treatment of substance use disorders (SUDs). Ongoing engagement in continuing care, including mutual support (e.g., 12-step groups) and/or professional outpatient services, may enhance treatment outcomes and facilitate recovery.

OBJECTIVE

This study investigates how engagement in 12-step mutual support and professional outpatient services is associated with short-term substance use outcomes in a sample of patients who completed inpatient SUDs treatment.

METHODS

As part of the Recovery Journey Project - a longitudinal cohort study - participants completed questionnaires upon admission to an inpatient SUDs treatment program, and at 1- and/or 3-months post-discharge (n = 379). Baseline data were collected by self-administered, electronic questionnaires. Follow up data were collected by phone or email. Analyses involved multivariate Generalized Estimating Equations separately modelling self-reported abstinence and percent days abstinent (PDA) over the three time periods.

RESULTS

Overall, rates of self-reported abstinence and PDA increased significantly from baseline to 1- and 3-months follow up. Engagement in 12-step activities (i.e., attended 30 meetings in 30 days, had a home group, had a sponsor, did service work) and professional outpatient substance use support were each significantly associated with abstinence and PDA. Participants who reported a higher degree of 12-step involvement (defined as engagement in more 12-step activities) were also more likely to report being abstinence and greater PDA.

CONCLUSIONS

Engagement in continuing care, including 12-step activities and professional outpatient substance use support, was highly associated with substance use. Clinical teams should encourage participation in such activities to optimize treatment outcomes.
