Behavioral couples therapy (BCT) is more efficacious than individually-based therapy (IBT) for substance and relationship outcomes among substance use disorder patients. This study compared BCT with IBT for drug-abusing women.
Sixty-one women, mostly White, late 30s, with primary substance use disorder other than alcohol (74% opioid), and male partners were randomized to 26 sessions over 13 weeks of BCT plus 12-step-oriented IBT (i.e., BCT + IBT) or IBT. Substance-related outcomes were percentage days abstinent (PDA), percentage days drug use (PDDU), Inventory of Drug Use Consequences. Relationship outcomes were Dyadic Adjustment Scale (DAS), days separated. Data were collected at baseline, posttreatment, and quarterly for 1-year follow-up.
On PDA, PDDU, and substance-related problems, both BCT + IBT and IBT patients showed significant (p < .01) large effect size improvements throughout 1-year follow-up (d > .8 for most time periods). BCT + IBT showed a significant (p < .001) large effect size (d = -.85) advantage versus IBT on fewer substance-related problems, while BCT + IBT and IBT did not differ on PDA or PDDU (ps > .47). On relationship outcomes, compared to IBT, BCT + IBT had significantly higher male-reported Dyadic Adjustment Scale (p < .001, d = .57) and fewer days separated (p = .01, d = -.47) throughout 1-year follow-up.
BCT + IBT for drug-abusing women was more efficacious than IBT in improving relationship satisfaction and preventing relationship breakup. On substance use and substance-related problems, women receiving both treatments substantially improved, and women receiving BCT + IBT had fewer substance-related problems than IBT.

对于物质使用障碍患者，行为夫妻治疗（BCT）在物质及关系改善方面比个体治疗（IBT）更有效。本研究比较了BCT与IBT对吸毒女性的效果。
61名女性（大多为白人，30多岁晚期），患有除酒精外的原发性物质使用障碍（74%为阿片类药物成瘾），其男性伴侣被随机分配接受为期13周的26次治疗，一组为BCT加以12步为导向的IBT（即BCT + IBT），另一组为IBT。与物质相关的结果指标包括戒断天数百分比（PDA）、吸毒天数百分比（PDDU）、药物使用后果量表。关系结果指标包括二元调适量表（DAS）、分居天数。在基线、治疗后以及为期1年随访的每季度收集数据。
在PDA、PDDU以及与物质相关的问题上，BCT + IBT组和IBT组患者在整个1年随访期间均显示出显著（p <.01）的大效应量改善（大多数时间段d>.8）。在物质相关问题较少方面，BCT + IBT组相对于IBT组显示出显著（p <.001）的大效应量（d = -.85）优势，而BCT + IBT组和IBT组在PDA或PDDU上没有差异（p>.47）。在关系结果方面，与IBT相比，在整个1年随访期间，BCT + IBT组男性报告的二元调适量表得分显著更高（p <.001，d =.57），分居天数更少（p =.01，d = -.47）。
对于吸毒女性，BCT + IBT在改善关系满意度和预防关系破裂方面比IBT更有效。在物质使用和与物质相关的问题上，接受两种治疗的女性都有显著改善，且接受BCT + IBT的女性比接受IBT的女性有更少的物质相关问题。（PsycINFO数据库记录
