Understanding intersectional stigma and substance use through GPS spatial mobility data

摘要 此多样性补充的目标是利用全球定位系统(GPS)的空间流动性数据来 指导深入的定性访谈，考察交叉少数民族的前因和后果 HIV阴性黑人和拉丁裔使用兴奋剂的性少数族裔男性(SMM)的压力。黑人和Latinx SMM 体验与艾滋病毒有关的严重健康差距，这种差距因同时使用兴奋剂而放大。2018年， 美国所有新的艾滋病毒感染者中，47%是黑人和拉丁裔SMM。重叠的结构性因素，如 建筑环境中的种族主义、异性恋主义、监禁和城市迁移模式是重要的 这些种族差距的驱动因素。使用GPS跟踪来分析空间流动性将使我们能够使用客观 位置数据与参与者的叙述配对，解释特定空间内的互动如何导致 羞辱经历，以及这些经历如何影响物质使用行为。我们可以用这个配对的，混合的 将暴露置于结果之前的方法，即之前的环境运动 相交的污名和相应物质的使用。这是GPS方法的一种新的应用 增进我们对交叉污名的理解。据我们所知，之前没有任何研究使用GPS数据 了解空间流动性对交叉污名、刺激剂使用、以及 艾滋病毒风险。 我们将招募30名艾滋病毒阴性的黑人和拉丁裔少数族裔男性，他们居住在佛罗里达州南部，他们使用兴奋剂 作为父R01的一部分。实施混合方法设计，首先从参与者那里收集GPS数据进行绘图 他们在不同兴趣领域的地域流动性，包括工作、家庭、社交和性活动 在两周的时间跨度内。以下定性组件将利用移动性图来指导 深入的定性访谈，了解他们的动态动作与体验的关系 交叉污名因环境而异，以及这对他们的物质使用有什么影响(如果有的话)。 指导和培训：拟议的多样性补充培训计划由Adam Carrico博士赞助 达斯汀·邓肯博士和奥黛丽·哈克内斯博士共同赞助。培训包括GPS的高级方法 空间流动性数据收集和分析、地理信息系统(GIS)计算方法、 设计和实施交叉污名定性研究、精神病理学、社会心理学、 和与成瘾有关的认知神经科学，以及艾滋病毒预防、护理和治疗科学。这种多样性 补充内容将为计划中的F32应用程序提供理想的基础，我将在此基础上进行以下工作 将生态瞬时评估(EMA)方法与GPS数据收集相结合，以了解 刺激兴奋剂使用和艾滋病毒风险的跨部门污名经历因环境背景而异。

ABSTRACT The goal of this diversity supplement is to leverage global positioning systems (GPS) spatial mobility data to guide in-depth qualitative interviews examining the antecedents and consequences of intersectional minority stress in HIV-negative Black and Latinx sexual minority men (SMM) who use stimulants. Black and Latinx SMM experience profound HIV-related health disparities that are amplified by co-occurring use of stimulants. In 2018, 47% of all new US HIV infections were among Black and Latinx SMM. Overlapping structural factors such as racism, heterosexism, incarceration, and urban migration patterns within the built environment are important drivers of these racial disparities. Use of GPS tracking to analyze spatial mobility will allow us to use objective location data paired with narratives from participants explaining how interactions within certain spaces lead to stigmatizing experiences, and how those impact substance use behaviors. We can use this paired, mixed method approaches to place to the exposure before the outcomes, i.e., the environmental movements before the intersectional stigma and consequential substance use. This is a novel application of GPS methods to advance our understanding of intersectional stigma. To our knowledge, no previous studies have used GPS data to understand the impact of spatial mobility on the relationships among intersectional stigma, stimulant use, and HIV risk. We will Enroll 30 HIV-negative Black and Latinx sexual minority men living in South Florida who use stimulants as part of parent R01. Implement a mixed-methods design, first collecting GPS data from participants to plot their geographic mobility within the different areas of interests, including work, home, social and sexual activity spaces over a two-week span. A following qualitative component would leverage the mobility maps to guide an in-depth qualitative interview to understand how their dynamic movements related to experiences of intersectional stigma vary across settings, and what (if any) implications this has for their substance use. Mentoring and Training: The proposed diversity supplement training plan is sponsored by Dr. Adam Carrico and co-sponsored by Drs. Dustin Duncan and Audrey Harkness. Training includes advanced methods in GPS spatial mobility data collection and analysis, geographic information systems (GIS) computation methodology, design and implementation of intersectional stigma qualitative research, psychopathology, social psychology, and cognitive neuroscience relevant to addiction, and HIV prevention, care and treatment science. This diversity supplement will provide an ideal foundation for a planned F32 application where I will build upon this work to integrate ecological momentary assessment (EMA) methods with GPS data collection to understand how the experiences of intersectional stigma that fuel stimulant use and HIV risk vary across environmental contexts.
