DESCRIPTION (provided by applicant): Alcohol consumption in sub-Saharan Africa is a major public health concern that has received insufficient attention. The World Health Organization (WHO) estimates that although 70% of adults in sub- Saharan Africa are self-reported abstainers, the 30% who report consuming alcohol have among the highest levels of per capita consumption in the world. The heavy, episodic pattern of consumption that characterizes alcohol use in this region is associated with many negative HIV-related consequences including an increased likelihood of engaging in high risk behavior and a higher cumulative risk of onward transmission among sero-discordant partnerships. The intersection of these two epidemics underscores the urgency of increased research attention and intervention development. Research aimed at understanding how, and in what contexts, alcohol is most likely to result in high risk behavior in sub-Saharan Africa has been dominated by cross-sectional study designs that fail to capture the temporal relationship between alcohol consumption and its subsequent effect on risky behavior. The overall objective of this K01 Career Development Award is to achieve a better understanding of the relationship between event-level alcohol use and high risk behavior among HIV-positive (HIV+) African adults using cell- phone based, daily data collection techniques. The long-term goal of this application is to develop a behavioral HIV prevention intervention targeting alcohol use that can be implemented with HIV+ adults in sub-Saharan Africa and to provide the principal investigator, Dr. Woolf-King, with the skills and training necessary to successfully develop and test the efficacy of this intervention. Dr. Woolf-King is trained as a clinical psychologist with expertise in the use of laboratory-based, alcohol administration studies for determining the causal effect of event-level alcohol intoxication on the behavior of high risk men, college students, and African American adults. Dr. Woolf-King's long-term goal is to become a successful NIH-funded behavioral scientist with international expertise in alcohol's relationship to HIV. She has proposed a combination of didactic and applied research activities, under the mentorship of experts in the field, to provide her with the following skills necessary to accomplish this goal: (1) the design and analysis of longitudinal event-level research, (2) the use of biological data to estimate the accuracy of self-reported behavior, and (3) the development of behavioral HIV prevention intervention development. The proposed research consists of three specific aims and will be conducted in conjunction with Dr. Judy Hahn's ongoing NIH/NIAAA-funded (R01 and U01) cohorts of ART-na¿ve, HIV+ African adults. Aim 1: Enhance our understanding of the event-level association between alcohol consumption and high risk behavior among HIV+ adults in Africa. We will accomplish this aim by: (a) conducting a prospective, event-level study with 100 HIV+ men (n= 50) and women (n =50) who report consuming alcohol in the last three months, (b) assessing the situational and relationship-level aspects of high risk events over a six- week period using interactive voice response (IVR) technology, and (c) using a theory-guided conceptual framework and advanced multilevel modeling to determine the extent to which individual, situational, and relationship-leve variables work together to explain the association between alcohol use and risky behavior. Aim 2: Estimate the accuracy of self-reported high risk behavior using biological data.. We will accomplish this aim by: (a) using a qualitative test for Prostate Specific Antigen (PSA), an indicator of recent (i.e., last 24 hours) semen exposure that can be reliably recovered from self-administered vaginal swabs, (b) comparing these PSA tests to self-report of risky behavior in the last 24 hours, and (c) using women with positive PSA tests to estimate self-report bias. Aim 3: Develop a plan for an intervention targeting alcohol use and high risk behavior that incorporates event-level data collected with IVR. We will accomplish this aim by: (a) conducting brief qualitative exit interviews with a sub-group of participants in the event-level study to assess the feasibility and acceptability of IVR as a self-monitoring device, (b) using an existing alcohol use risk reduction intervention to guide us in translating these self-monitoring data into personalized feedback that highlights the within-person variability in alcohol's relationship to risky behavior and (c) ultimately developing a new brief, patient-centered HIV risk-reduction intervention for high risk, alcohol consuming HIV+ adults in Africa. These research activities will culminate in the submission of an R34 as part of NIAAA's Behavioral and Integrative Treatment Development Program, during the 4th year of the K-award period, to further develop and pilot test the intervention that emerges from these specific aims. This will lead directly to the submission of an R01 to conduct a full Randomized Controlled Trial (RCT) of the intervention to determine its efficacy. The career development and research activities proposed in this K01 application will lay the foundation for Dr. Woolf-King's career as successful, independent, NIH-funded behavioral scientist with the skills to conduct a wide-range of research on alcohol's relationship to the HIV epidemic, both domestically and internationally.

描述(申请人提供)：撒哈拉以南非洲的酒精消费是一个主要的公共卫生问题，但没有得到足够的重视。世界卫生组织(WHO)估计，尽管撒哈拉以南非洲70%的成年人自我报告戒酒，但报告饮酒的30%的人是世界上人均饮酒量最高的国家之一。该地区大量、间歇性的饮酒模式与许多与艾滋病毒相关的负面后果有关，包括从事高风险行为的可能性增加，以及在血清不一致的伴侣中继续传播的累积风险更高。这两种流行病的交叉突显了加强研究关注和干预发展的紧迫性。 旨在了解酒精如何以及在什么情况下最有可能在撒哈拉以南非洲导致高风险行为的研究一直被横断面研究设计所主导，这些设计未能捕捉到酒精消费及其对危险行为的后续影响之间的时间关系。K01职业发展奖的总体目标是利用基于手机的日常数据收集技术，更好地了解艾滋病毒阳性(HIV+)非洲成年人事件级别饮酒与高危行为之间的关系。这项应用的长期目标是开发一种针对酒精使用的行为艾滋病毒预防干预措施，可以在撒哈拉以南非洲的艾滋病毒+成年人中实施，并为首席研究员伍尔夫-金博士提供必要的技能和培训，以成功开发和测试这种干预措施的效果。 伍尔夫-金博士是一名临床心理学家，在使用基于实验室的 酒精管理研究，以确定事件级酒精中毒对高危男性、大学生和非裔美国成年人行为的因果影响。伍尔夫-金博士的长期目标是成为美国国立卫生研究院资助的一名成功的行为科学家，在酒精与艾滋病毒的关系方面拥有国际专业知识。她建议在该领域专家的指导下，结合教学和应用研究活动，为她提供实现这一目标所需的以下技能：(1)纵向事件水平研究的设计和分析，(2)使用生物数据估计自我报告行为的准确性，以及(3)制定行为艾滋病毒预防干预措施。拟议的研究包括三个具体目标，并将与朱迪·哈恩博士正在进行的由NIH/NIAAA资助(R01和U01)的ART-NA、HIV+非洲成年人队列一起进行。 目标1：加强我们对非洲艾滋病毒携带者成人中饮酒和高危行为之间的事件级别联系的理解。我们将通过以下方式实现这一目标：(A)对100名艾滋病毒携带者(n=50)和报告在过去三个月内饮酒的女性(n=50)进行前瞻性的事件水平研究，(B)使用交互式语音应答(IVR)技术在六周的时间内评估高风险事件的情景和关系层面，以及(C)使用理论指导的概念框架和先进的多水平建模来确定个人、情景和关系层面的变量在多大程度上共同解释酒精使用和风险行为之间的关联。 目的2：使用生物学数据估计自我报告的高危行为的准确性。我们将通过以下方式实现这一目标：(A)使用前列腺特异性抗原(PSA)的定性测试，这是最近(即最近24小时)精液暴露的一个指标，可以从自我给药的阴道拭子中可靠地恢复，(B)将这些PSA测试与过去24小时内危险行为的自我报告进行比较，以及(C)使用PSA测试阳性的女性来估计自我报告的偏差。 目标3：制定一项针对酒精使用和高危行为的干预计划，其中包括通过IVR收集的事件级数据。我们将通过以下方式实现这一目标：(A)对事件级研究中的一组参与者进行简短的定性离职访谈，以评估IVR作为一种自我监测工具的可行性和可接受性；(B)利用现有的酒精使用风险降低干预措施，指导我们将这些自我监测数据转化为个性化反馈，强调酒精与危险行为之间的关系；以及(C)最终为非洲高风险、饮酒的艾滋病毒+成年人开发一种新的简短、以患者为中心的艾滋病毒降低风险干预措施。 这些研究活动将最终提交R34，作为NIAAA行为和综合治疗发展计划的一部分，在K奖期间的第四年，以进一步开发和试点测试从这些特定目标产生的干预措施。这将直接导致提交R01，以进行干预的全面随机对照试验(RCT)，以确定其有效性。这份K01申请中提出的职业发展和研究活动将为伍尔夫-金博士的职业生涯奠定基础，他是一名成功的、独立的、由NIH资助的行为科学家，拥有在国内和国际上就酒精与艾滋病毒流行的关系进行广泛研究的技能。
