Behavioural couples therapy (BCT) and alcohol behavioural couples therapy (ABCT) are couples-based interventions for substance use disorders (SUDs) that have been deemed a ‘gold standard’ treatment. Despite the substantial amount of promising research, there is a lack of research on the active components of treatment and treatment mechanisms and moderators. Since the most recent meta-analysis, a number of studies have been conducted that advance our understanding of the efficacy of BCT and ABCT.

The purpose of the present review was to provide an update on the current knowledge of these treatments and to investigate mediators and moderators of treatment.

A systematic search strategy of relevant databases from 2008 to 2021 identified 20 relevant articles that were coded for relevant information including study design, treatment, outcomes, as well as mechanisms and moderators.

The results indicated that BCT and ABCT are successful in reducing alcohol and substance use for both male and female clients, dual problem couples, and for reducing post-traumatic stress symptoms and intimate partner violence. The reviewed studies discussed a number of treatment mechanisms, with the most studied mechanism being relationship functioning. Moderators included relationship functioning and patient gender.

The results point to the need for additional research on active treatment components, mechanisms and moderators, in order to provide a more efficient and cost-effective treatment.

夫妻行为疗法 (BCT) 和酒精行为夫妻疗法 (ABCT) 是针对物质使用障碍 (SUD) 的夫妻干预措施，被视为“黄金标准”治疗。尽管有大量有前景的研究，但仍缺乏对治疗的活性成分、治疗机制和调节剂的研究。自最近的荟萃分析以来，已经进行了许多研究，以促进我们对 BCT 和 ABCT 功效的理解。

本综述的目的是提供有关这些治疗的当前知识的最新信息，并调查治疗的介质和调节剂。

对 2008 年至 2021 年相关数据库的系统搜索策略确定了 20 篇相关文章，这些文章针对相关信息进行了编码，包括研究设计、治疗、结果以及机制和调节因素。

结果表明，BCT 和 ABCT 成功地减少了男性和女性客户、双重问题夫妇的酒精和物质使用，并减少了创伤后压力症状和亲密伴侣暴力。审查的研究讨论了许多治疗机制，其中研究最多的机制是关系功能。主持人包括关系功能和患者性别。

结果表明需要对活性治疗成分、机制和调节剂进行更多研究，以提供更有效和更具成本效益的治疗。
