Web-Based Intervention for Black Bisexually-Active Men

描述(由申请人提供)：非裔美国人受艾滋病毒/艾滋病的影响不成比例，这种差异在双性活跃的非裔美国人男性(BAAM)中更加明显。然而，对BAAM的性危险行为及其发生的背景了解不足。到目前为止，文献中还没有对不注射药物的BAAM开发和评估在减少HIV相关性行为方面有效的干预措施。这项拟议的研究将开发和测试一种创新的个人定制和文化敏感的6节在线视频干预的有效性和可接受性，该视频干预同时针对BAAM中与注意控制(教育)条件有关的艾滋病毒风险行为的多个领域的社会文化、结构层面和背景因素。这种干预在内容(使用信息-动机-行为技能模型)和交付(使用社会认知理论)两个方面都得到了理论上的了解，并将以同龄人BAAM为特色。行为和生物结果都将被测量。使用受访者驱动的抽样，总共120名BAAM将被登记并随机分配到治疗或教育控制条件下。他们将被纵向跟踪六个月(在基线、第三个月和第六个月进行评估)。除了确定BAAM中终生和近期艾滋病毒相关危险行为的流行率外， 这项研究试图评估短期干预在三个领域随时间的影响：(1) 减少艾滋病毒相关危险行为的意图/动机，(2)自我报告的艾滋病毒相关危险行为，以及(3)健康/预防知识和自我效能技能。拟议项目的长期目标是开发一种经验性验证的艾滋病毒/性传播感染预防计划，该计划可以在BAAM在线提供。与R34机制一致，最终产品将成为 在该人群中进行大规模疗效研究的R01应用程序。这一干预是否应该 如果证明有效，这将是一种成本可行的方法，可以防止艾滋病毒在BAAM之间的传播，通过许多男男性行为者(包括BAAM)积极结交性伴侣(即互联网)的媒介来传播。最后，这种干预模式可以很容易地被艾滋病毒服务提供者采用，并在各种人群的传统临床环境之外提供。

Description (provided by the applicant): African Americans are disproportionately affected by HIV/AIDS, and this disparity is further evident among bisexually-active African American men (BAAM).Yet, there is insufficient knowledge regarding sexual risk behaviors of BAAM and the context in which they occur. To date, no interventions in the literature with demonstrated efficacy in reducing HIV-related sexual risk behaviors have been developed and evaluated for BAAM who do not inject drugs. The proposed study will develop and test the efficacy and acceptability of an innovative individually-tailored and culturally-sensitive 6-session online-delivered video intervention that simultaneously targets multiple domains of socio-cultural, structural-level factors, and contextual factors related to HIV risk behavior among BAAM, relative to an attention control (education) condition. This intervention is theoretically informed both in content (using the Information-Motivation-Behavior Skills model) and delivery (using tenets of Social Cognitive theory) and will feature peer BAAM. Both behavioral and biologic outcomes will be measured. Using respondent-driven sampling, a total of 120 BAAM will be enrolled and randomly assigned to either treatment or education-control conditions. They will be longitudinally tracked for six months (assessed at Baseline, month 3, and month 6). In addition to determining the prevalence of lifetime and recent HIV-associated risk behavior among BAAM, this study seeks to evaluate the impact of a brief intervention across three domains over time: (1) intentions/motivations to reduce HIV-associated risk behavior, (2) self-reported HIV-associated risk behavior, and (3) health/prevention knowledge and self-efficacy skills. The long term goal of the proposed project is to develop an empirically validated HIV/STI prevention program that can be delivered online BAAM. Consistent with the R34 mechanism, the final product will be the basis for an R01 application to conduct a large-scale efficacy study in this population. Should this intervention demonstrate effective, it will be a cost feasible approach to preventing HIV transmissions among BAAM, delivered via the medium where many men who have sex with men (including BAAM) actively meet sex partners (i.e., the Internet). Finally, the model for this intervention can easily be adopted by HIV service providers and delivered outside of traditional clinical setting with a variety of populations.
