Does Age Moderate the Effect of Spirituality/Religiousness in Accounting for Alcoholics Anonymous Benefit?

Gains in spiritual/religious (S/R) practices among Alcoholics Anonymous (AA) members are associated with reductions in drinking. This study had the following aims: (a) examine spirituality/religiousness as a mediator of the relationship between AA attendance and reductions in drinking behavior to replicate past research findings and to (b) examine age-cohort as a moderator of the mediational analyses given that empirical evidence (e.g., generational differences in spirituality) suggests that age may influence the acquisition of gains in spirituality/religiousness during AA as well as the expression of these gains on drinking behavior.

Measures were administered to 253 participants recruited from community-based AA and outpatient treatment programs at baseline, 3, 6, 9, and 12-months, and 210 (83%) participants provided complete data to test study aims.

Gains in S/R practices mediated the relationship between AA attendance and increased abstinence, but not drinking intensity. Simple slopes analyses indicated a positive association between AA attendance and gains in S/R practices among younger AA affiliates but not older AA affiliates in the moderated-mediational analyses. However, age was not found to moderate the global mediational effect.

The results from the current study inform efforts to increase positive change in AA affiliates' drinking behavior by highlighting specific aspects of S/R practices that should be targeted based on the age of an AA affiliate.
