项目摘要

DESCRIPTION (provided by applicant): HIV-infected current and former drug users have received disproportionately less benefit from antiretroviral therapy than non-drug users, in part because of sub-optimal adherence. Despite the clinical importance of adherence assessments and a large body of recent literature on antiretroviral adherence, there is no single adherence measure that is universally accepted in clinical or research settings. The lack of methodogical rigor in adherence measurement is particularly significant in intervention trials and may lead investigators to draw erroneous conclusions. Composite adherence measures may become the gold standard for assessing the complex and dynamic behavior of medication adherence in research studies, but such measures are only beginning to be evaluated. In clinical settings, imprecise adherence estimates can result in inaccurate targeting of interventions and poor clinical outcomes. Self-report is the most feasible, flexible, and widely used measure, but the relative validity of different self-report measures is unknown. To address these issues, I propose to study adherence measurement in current and former drug users. The specific aims of this proposal are: (1) to develop a composite antiretroviral adherence measurement model that incorporates four methods of measurement (self-report, pill count, pharmacy refill records, and MEMS), and to compare the correlation with HIV viral load of the composite model with the correlation of each single method; (2) to examine the agreement between common antiretroviral adherence self-report measures, and to determine the validity of each measure by assessing its correlation with a new adherence measurement gold standard (composite antiretroviral adherence model) and an adherence surrogate (HIV viral load); and (3) to describe the cognitive processes undertaken by current and former drug users to answer self-report antiretroviral adherence questions, including question interpretation, ability to remember medication taking, and answer editing. My major goal is to become an independent clinical investigator with expertise in behavioral substance abuse research. The career development plan I have proposed includes mentorship in antiretroviral adherence, behavioral research methods, and substance abuse research, coupled with formal coursework and participation in local interactive seminars and national scientific meetings.

描述(申请人提供)：感染艾滋病毒的现任和前任吸毒者从抗逆转录病毒治疗中获得的好处比非吸毒者少得不成比例，部分原因是依从性不佳。尽管依从性评估的临床重要性，以及大量关于抗逆转录病毒依从性的最新文献，但没有一种单一的依从性衡量标准在临床或研究环境中得到普遍接受。依从性测量缺乏方法学的严谨性在干预试验中尤其明显，可能会导致研究人员得出错误的结论。复合依从性测量可能成为评估研究中用药依从性的复杂和动态行为的金标准，但此类测量才刚刚开始评估。在临床环境中，不准确的依从性估计可能会导致干预目标的不准确和不良的临床结果。自我报告是最可行、最灵活、使用最广泛的测量方法，但不同的自我报告测量方法的相对效度尚不清楚。为了解决这些问题，我建议研究现任和前任吸毒者的依从性测量。这项建议的具体目的是：(1)开发一个综合的抗逆转录病毒依从性测量模型，包括四种测量方法(自我报告、药片计数、药房再灌装记录和MEMS)，并比较复合模型与HIV病毒载量的相关性和每一种方法的相关性；(2)检查常见的抗逆转录病毒依从性自我报告措施之间的一致性，并通过评估其与新的依从性测量金标准(复合抗逆转录病毒依从性模型)和依从性替代物(HIV病毒载量)的相关性来确定每种措施的有效性；以及(3)描述现任和前任吸毒者回答自我报告的抗逆转录病毒依从性问题的认知过程，包括问题解释、记住药物服用的能力和答案编辑。我的主要目标是成为一名独立的临床调查员，在行为药物滥用研究方面拥有专业知识。我提出的职业发展计划包括在抗逆转录病毒依从性、行为研究方法和药物滥用研究方面的指导，以及正式的课程作业和参加当地的互动研讨会和国家科学会议。
