Behavioral interventions have utilized a variety of strategies and components to reduce HIV risk. This article describes the partner intervention, a couple-based group HIV risk reduction intervention implemented in 6 urban community health clinics in Lusaka, Zambia, and examines the components of the intervention and their relationship with condom use. Couple members completed assessments on condom use, acceptability, willingness to use condoms, communication, intimate partner violence (IPV), self-efficacy, and HIV information at baseline and 6 months' follow-up. This study examined the relative impact of elements of the intervention as predictors of condom use. Changes in acceptability had the greatest overall influence on condom use, followed by social support, relationship consensus, and willingness to use condoms. Changes in self-efficacy, IPV, negotiation, and information had no influence. Results support the use of multidimensional approaches in behavioral interventions and highlight the importance of identifying critical elements of interventions to maximize risk reduction outcomes.
行为干预采用了多种策略和组成部分来降低感染艾滋病毒的风险。本文介绍了伴侣干预措施，这是一种在赞比亚卢萨卡的6家城市社区卫生诊所实施的、以夫妻为基础的降低艾滋病毒风险的团体干预措施，并研究了该干预措施的组成部分及其与避孕套使用的关系。夫妻双方在基线和6个月随访时完成了关于避孕套使用、可接受性、使用避孕套的意愿、沟通、亲密伴侣暴力、自我效能感和艾滋病毒信息的评估。本研究考察了干预措施各要素作为避孕套使用预测因素的相对影响。可接受性的变化对避孕套使用的总体影响最大，其次是社会支持、关系共识和使用避孕套的意愿。自我效能感、亲密伴侣暴力、协商和信息方面的变化没有影响。研究结果支持在行为干预中采用多维度方法，并强调识别干预的关键要素以最大化降低风险结果的重要性。
