Abstract

Objective: Although research supports an association between increased alternative reinforcement and decreased substance use, the impact of substance use on changes in reinforcement during posttreatment recovery remains untested. This study tested the effect of abstinence duration and substance use frequency on the trajectories of four reinforcement mechanisms, behavioral activation, reward probability, reward barriers, and valued living, from pre- to 12-month posttreatment.

Method: Adults in intensive outpatient substance use disorder treatment (N = 206) completed self-report measures of the four reinforcement constructs and substance use over six timepoints from pre- to 12-month posttreatment. Latent curve models were used to test the association between reinforcement trajectories and abstinence duration and substance use frequency, respectively.

Results: Lower substance use frequency was associated with significantly improved behavioral activation, reward probability, and reward barriers across the posttreatment period (ps < .05). Higher substance use frequency was associated with significantly lower valued living at each timepoint (ps < .05). Longer abstinence duration was significantly associated with higher behavioral activation and valued living, and lower reward barriers at 12-months (ps < .05).

Conclusions: Substance-free reinforcement improves during treatment and is negatively impacted by substance use frequency during posttreatment. Abstinence duration is positively associated with substance-free reinforcement at 12-month posttreatment. These findings support the conceptualization of reinforcement as a malleable treatment target that is negatively impacted by substance use.

药物使用对药物使用治疗后一年的强化变化产生负面影响。

目的：虽然研究支持增加替代强化和减少物质使用之间的关联，但在治疗后恢复期间，物质使用对强化变化的影响仍未得到检验。本研究考察了戒断时间和药物使用频率对四种强化机制（行为激活、奖励概率、奖励障碍和生活价值）的影响。方法：门诊重症药物使用障碍治疗的成人（N = 206）在治疗前至治疗后12个月的6个时间点完成了四种强化结构和药物使用的自我报告测量。使用潜曲线模型分别检验强化轨迹与戒断持续时间和物质使用频率之间的关系。结果：低物质使用频率与治疗后行为激活、奖励概率和奖励障碍显著改善相关（ps < 0.05）。较高的药物使用频率与各时间点的生活价值显著降低相关（ps < 0.05）。较长的戒断持续时间与12个月时较高的行为激活和生活价值以及较低的奖励障碍显著相关（ps < 0.05）。结论：无物质强化在治疗期间得到改善，治疗后药物使用频率对无物质强化有负向影响。戒断持续时间与治疗后12个月无物质强化呈正相关。这些发现支持强化作为可塑治疗目标的概念化，它受到物质使用的负面影响。（PsycInfo Database Record (c) 2025 APA，版权所有）。
