Dynamics of HIV Risk Behavior: A Daily Process Approach

描述(由申请人提供)：拟议研究的目的是使用每日过程的方法来了解与艾滋病毒阳性南非人的艾滋病毒危险行为有关的心理社会和社会认知因素。研究的第一阶段将包括开发、试点测试和完善结构化的每日日记，以评估压力、情感状态、应对、社会认知因素、物质使用和艾滋病毒风险行为。这本日记将被用来收集140名HIV阳性患者为期6周的日常数据。多水平建模将被用来测试所提出的压力和艾滋病毒危险行为之间的联系，并探索这种关系如何在艾滋病毒阳性个人的日常生活中展开的可能机制。这将导致理解每天的应激事件以及个人对这些事件的反应最终如何影响艾滋病毒风险行为。这项研究是首批考察日常应激事件作为与艾滋病毒危险行为相关的因素的作用，并接近实时地衡量艾滋病毒危险行为的预测因素的研究之一。这些发现可能会建议采取有效的战略，对艾滋病毒阳性的人进行干预，并防止在南非艾滋病毒阴性的人中进一步感染艾滋病毒。

DESCRIPTION (provided by applicant): The purpose of the proposed research is to use a daily process approach to understand the psychosocial and social cognitive factors related to HIV risk behavior among HIV positive South African individuals. The first phase of the research will involve developing, pilot testing, and refining a structured daily diary to assess stress, affective states, coping, social cognitive factors, substance use, and HIV risk behavior. This diary will be used to collect daily data for 6-weeks from 140 HIV positive individuals. Multilevel Modeling will be utilized to test the proposed association between stress and HIV risk behavior and explore possible mechanisms as to how such a relationship may unfold in HIV positive individuals daily lives. This will result in an understanding of how stressful daily events and an individual's responses to these events ultimately affect HIV risk behavior. This research represents one of the first studies to examine the role of daily stressful events as factor related to HIV risk behavior, and to measure predictors of HIV risk behavior close to real-time. These findings may suggest effective strategies to intervene with HIV positive individuals and to prevent further HIV infections among HIV negative individuals in South Africa.
