Shifts in behavioral allocation patterns as a natural recovery mechanism: Postresolution expenditure patterns.

BACKGROUND

Behavioral economics predicts that recovery from Alcohol Use Disorder involves shifts in resource allocation away from drinking, toward valuable nondrinking rewards that reinforce and stabilize recovery behavior patterns. Further, these shifts should distinguish nonproblem drinking (moderation) outcomes from outcomes involving abstinence or relapse. To evaluate these hypotheses, 5 prospective studies of recent natural recovery attempts were integrated to examine changes in monetary spending during the year following the initial cessation of heavy drinking as a function of 1-year drinking outcomes.

METHODS

Problem drinkers from Southeastern U.S. communities (N = 493, 67% male, 65% white, mean age = 46.5 years) were enrolled soon after stopping heavy drinking without treatment and followed prospectively for a year. An expanded Timeline Followback interview assessed daily drinking and monetary spending on alcohol and nondrinking commodities during the year before and after recovery initiation.

RESULTS

Longitudinal associations between postresolution drinking and spending were evaluated using MPlus v.8. Initial models evaluated whether changes in spending at 4-month intervals predicted drinking outcomes at 1 year and showed significant associations in 6 commodity categories (alcohol, consumable goods, gifts, entertainment, financial/legal affairs, housing/durable goods/insurance; ps < 0.05). Cross-lagged models showed that the moderation outcome group shifted spending mid-year to obtain large rewards with enduring benefits (e.g., housing), whereas the abstinent and relapsed groups spent less overall and purchased smaller rewards (e.g., consumable goods, entertainment, and gifts) throughout the year.

CONCLUSIONS

Dynamic changes in monetary allocation occurred during the postresolution year. As hypothesized, compared to the groups who abstained or relapsed, the moderation group shifted spending in ways that, overall, yielded higher value alcohol-free reinforcement that should reinforce recovery while they enjoyed some limited nonproblem drinking below heavy drinking thresholds. These findings add to evidence that moderation entails different behavioral regulation processes than abstinent and relapse outcomes, which were more similar to one another.
