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，这种差异在双性恋活跃的非裔美国男性（BAAM）中进一步明显。然而，人们对BAAM的性危险行为及其发生的背景了解不足。到目前为止，文献中还没有针对不注射毒品的BAAM开发和评估有效的干预措施，以减少与艾滋病毒相关的性风险行为。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次在线视频干预的有效性和可接受性，同时针对BAAM中与艾滋病毒风险行为相关的社会文化，结构层面因素和背景因素的多个领域，相对于注意控制（教育）条件。这种干预在内容（使用信息-动机-行为技能模型）和传递（使用社会认知理论的原则）方面理论上都是知情的，并将以同伴BAAM为特色。行为和生物学结果都将被测量。采用受访者驱动的抽样方法，总共将招募120名BAAM，并随机分配到治疗组或教育对照组。他们将被纵向跟踪6个月（在基线、第3个月和第6个月进行评估）。除了确定BAAM中终生和近期艾滋病毒相关风险行为的患病率外，

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.
