OBJECTIVE Although low-income couples experience greater relationship challenges, they have limited access to effective relationship interventions. Furthermore, most previous efforts to improve low-income couples' relationships have yielded very small effects (Hawkins & Erickson, 2015). In an effort to overcome these limitations, this study investigated the effectiveness of 2 web-based interventions for low-income couples. METHOD In total, 742 low-income couples (N = 1,484 individuals; mean [M] age = 33; 55% White, non-Hispanic; 52% married; median [Mdn] annual household income = $27,000) were recruited nationally and randomized to the OurRelationship program, the ePREP program, or a waitlist control group. Couples were repeatedly assessed for 6 months using self-report measures of relationship satisfaction, communication conflict, intimate partner violence, emotional support, and breakup potential. Relationship status was assessed at 6-month follow-up. RESULTS Compared to the control group, intervention couples experienced significantly greater improvements in all 5 domains of relationship functioning (Mdn |d| = 0.46) by the end of the program; these effects were maintained in the 4 months after treatment. However, neither program significantly reduced the frequency of breakups by the 6-month follow-up. Differences between couples in the two interventions were minimal (Mdn Cohen's |d| = 0.11); however, couples in the OurRelationship program experienced significantly greater decreases in conflict (d = 0.24). CONCLUSIONS The results indicate that brief, web-based interventions can serve a central role in delivering effective services to low-income couples. Additionally, the general equivalence of the two interventions indicates that both communication-focused and problem-focused interventions can be successful in improving the relationship functioning of low-income couples.

在线程序改善了陷入困境的低收入夫妻的关系功能：一项全国性随机对照试验的结果。

目的尽管低收入夫妇在关系方面面临更大挑战，但他们获得有效的关系干预措施的机会有限。此外，以前为改善低收入夫妇的关系所做的大多数努力都产生了很小的影响（Hawkins＆Erickson，2015）。为了克服这些限制，本研究调查了2种基于网络的干预措施对低收入夫妇的有效性。方法在全国范围内招募了742对低收入夫妇（N = 1,484个人；平均[M]年龄= 33； 55％非西班牙裔白人； 52％结婚；家庭年平均中位收入= $ 27,000），并进行了随机分组到OurRelationship程序，ePREP程序或候补列表控制组。使用自我报告的关系满意度，沟通冲突，亲密伴侣的暴力，情感支持和分手的潜力。在六个月的随访中评估了关系状况。结果与对照组相比，到程序结束时，干预夫妇在关系功能的所有5个域（Mdn | d | = 0.46）上均获得了显着改善。这些效果在治疗后的4个月内得以保持。但是，两个程序都没有通过6个月的随访来显着降低分手的频率。两次干预中夫妻之间的差异很小（Mdn Cohen | d | = 0.11）；但是，OurRelationship计划中的夫妻冲突减少的幅度更大（d = 0.24）。结论结果表明，基于网络的简短干预可以在为低收入夫妇提供有效服务方面发挥核心作用。另外，两种干预措施的普遍等效性表明，以沟通为重点和以问题为重点的干预措施都可以成功地改善低收入夫妻的关系功能。（PsycINFO数据库记录（c）2020 APA，保留所有权利）。
