DESCRIPTION (provided by applicant): This resubmission focuses on assessing implementation and effectiveness of an evidence-based HIV risk reduction intervention ("Eban II") for HIV-serodiscordant, heterosexual African-American couples in two geographic areas (Oakland and Los Angeles, CA) that have a high prevalence of HIV and risk conditions among African Americans. This study builds upon the multi-site, NIMH-funded Eban randomized controlled trial, which resulted in the intended outcomes of increased condom use and reduced incidents of unprotected sexual intercourse among committed, serodiscordant couples. Now that efficacy has been established, it is appropriate to test the effectiveness of the intervention as delivered in community-based organizations (CBOs) that serve African American clients. Because the intervention itself is highly innovative, careful, in-depth attention needs to be paid to barriers and facilitators to implementation and sustainability, especially because the participating agencies have no experience with (but strong interest in) delivering treatment to couples. Our primary implementation aims are: (1) To facilitate implementation of an evidence-based intervention for HIV serodiscordant African American couples; specifically, to employ a theory-guided strategy to partner with the CBOs to expose providers to the intervention, facilitate its adoption and delivery with high fidelity, and sustain its use for nine months following the active implementation phase; and (2) Using mixed quantitative and qualitative methods, to document the implementation process and identify barriers and facilitators to adoption, fidelity, and sustainability. Our primary intervention effectiveness aim is to evaluate the effect of Eban II on behavioral and biological outcomes among 180 couples, specifically incidents of protected sex, proportion of condom use, and incident sexually transmitted infections. We also have a secondary aim to determine the cost-effectiveness of implementation, based on implementation costs and potential cost savings. To achieve these aims, a protocol-based implementation approach will be developed and studied using process evaluation mixed methods with conceptual guidance from the Program Change Model, a model of phased organizational change from exposure to adoption, implementation, and sustainability. The study will produce in-depth information regarding an implementation approach that incorporates multiple strategies and tools for optimal uptake and sustainability of this couples intervention. The effectiveness of Eban II will be assessed using a randomized delayed enrollment (waitlist) control design to evaluate the impact of treatment on outcomes at posttest and 3-month follow-up. This study will produce important information regarding the value of this model and model-guided implementation tools and strategies for use in implementing Eban II and other evidence- based programs in diverse treatment settings. Accordingly, research in HIV prevention, clinical effectiveness trials, and implementation will be informed by the study findings.

描述（由申请人提供）：本次重新提交的重点是评估两个地理区域（奥克兰和洛杉矶，加利福尼亚州）的艾滋病毒感染率和风险状况较高的艾滋病毒血清不一致、异性恋非裔美国夫妇的循证艾滋病毒风险降低干预措施（“Eban II”）的实施情况和有效性。这项研究建立在多个地点，NIMH资助的Eban随机对照试验，这导致了预期的结果，增加了安全套的使用，减少了承诺，血清不一致的夫妇之间的无保护性交的事件。既然已经确定了有效性，就应该测试为非裔美国人服务的社区组织（CBO）提供的干预措施的有效性。由于干预措施本身具有高度创新性，因此需要认真、深入地关注实施和可持续性的障碍和促进因素，特别是因为参与机构没有为夫妇提供治疗的经验（但对这方面有浓厚的兴趣）。我们的主要实施目标是：（1）促进对艾滋病毒血清不一致的非裔美国夫妇实施循证干预;具体而言，采用理论指导战略，与社区组织合作，使提供者了解干预措施，促进其采用和高保真交付，并在积极实施阶段后持续使用9个月;以及（2）使用定量和定性相结合的方法，记录实施过程，并确定采用、忠实性和可持续性的障碍和促进因素。我们的主要干预有效性的目的是评估Eban II对180对夫妇的行为和生物学结果的影响，特别是保护性行为的发生率，避孕套的使用比例和性传播感染的发生率。我们还有一个次要目标，即根据实施成本和潜在的成本节约，确定实施的成本效益。为了实现这些目标，将开发和研究基于协议的实施方法，使用过程评估混合方法，并从计划变更模型（一种从暴露到采用、实施和可持续性的分阶段组织变更模型）中获得概念指导。这项研究将提供关于实施方法的深入资料，其中包括多种战略和工具，以最佳方式采用和持续实施这一夫妇干预措施。将使用随机延迟入组（等待名单）对照设计评估Eban II的有效性，以评价治疗对后测和3个月随访结局的影响。本研究将提供关于该模型的价值以及模型指导的实施工具和策略的重要信息，用于在不同治疗环境中实施Eban II和其他循证方案。因此，艾滋病毒预防、临床有效性试验和实施方面的研究将参考研究结果。
