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.
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.
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.
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.
行为经济学预测,从酒精使用障碍中恢复涉及资源分配的转变,从饮酒转向有价值的非饮酒奖励,以加强和稳定恢复行为模式。此外,这些转变应该区分非问题饮酒(适度)结果和涉及戒酒或复发的结果。为了评估这些假设,整合了 5 项最近自然康复尝试的前瞻性研究,以研究在初始停止大量饮酒后的一年中,作为 1 年饮酒结果的函数,货币支出的变化。
来自美国东南部社区的问题饮酒者(N=493,67%为男性,65%为白人,平均年龄为 46.5 岁)在未经治疗停止大量饮酒后不久即被招募,并进行了为期一年的前瞻性随访。扩展的时间线回溯访谈评估了康复启动前和启动后一年中每天的饮酒和酒精及非饮酒商品的货币支出。
使用 MPlus v.8 评估了康复后饮酒和支出之间的纵向关联。初始模型评估了 4 个月间隔的支出变化是否预测了 1 年的饮酒结果,并在 6 个商品类别(酒精、消费品、礼物、娱乐、金融/法律事务、住房/耐用商品/保险)中显示出显著关联(ps<0.05)。交叉滞后模型显示,适度组在年中转向支出以获得大的奖励,这些奖励具有持久的好处(例如住房),而戒酒和复发组在整个一年中支出较少,购买较小的奖励(例如消费品、娱乐和礼物)。
在康复后一年中,货币分配发生了动态变化。正如假设的那样,与戒酒或复发组相比,适度组的支出转变方式总体上产生了更高价值的无酒精强化,这应该在他们享受低于大量饮酒阈值的一些有限非问题饮酒的同时加强康复。这些发现增加了证据表明,适度比戒酒和复发结果涉及不同的行为调节过程,后者彼此更为相似。
