Men who have sex with men (MSM) of color are disproportionately affected by HIV in the United States. Pre-exposure prophylaxis (PrEP) using antiretroviral medications is a newer biomedical prevention modality with established efficacy for reducing the risk of acquiring HIV. We conducted formative qualitative research to explore audience reactions and receptivity to message concepts on PrEP as part of the development of prevention messages to promote PrEP awareness among black and Latino MSM in the United States. In 2013, 48 black and 42 Latino (total study sample = 90) mixed HIV serostatus MSM from Chicago, Ft. Lauderdale, and Kansas City participated in either an individual interview or focus group discussion. Men were recruited online and at community-based organizations in each city. We elicited feedback on the comprehensibility, credibility, and relevance of two draft messages on PrEP. The messages included efficacy estimates from iPrEx, a phase III clinical trial to ascertain whether the antiretroviral medication tenofovir/emtricitabine disoproxil fumarate (commercially known as Truvada) could safely and effectively prevent HIV acquisition through sex among MSM and transgender women. With participants' consent, the interviews and focus groups were recorded and transcribed. The data were then summarized and analyzed using a qualitative descriptive approach. The majority of men were unfamiliar with PrEP. It was suggested that additional information about the medication and clinical trials establishing efficacy was needed to enhance the legitimacy and relevancy of the messages. Participants sought to form an opinion of PrEP that was grounded in their own interpretation of the efficacy data. However, confusion about nonadherence among clinical trial subjects and individual versus average risk limited comprehension of these messages. Thematic overlaps suggest that message believability was connected to participants' ability to derive meaning from the PrEP efficacy data. Despite being concerned that other MSM would interpret the messages to mean that condom use was unnecessary while taking PrEP, participants themselves primarily understood PrEP as a supplement rather than a replacement for condoms. Based on their experience with taking antiretroviral medication, HIV-positive men considered condom use a more feasible form of HIV prevention than PrEP. Participants' responses suggest that more information about PrEP and the clinical trial would support the legitimacy of PrEP and the messages as a whole. These details may enhance believability in the concept of PrEP and reinforce confidence in the validity of the efficacy result.
在美国,有色人种男男性行为者(MSM)受艾滋病毒的影响尤为严重。使用抗逆转录病毒药物进行暴露前预防(PrEP)是一种较新的生物医学预防方式,已证实其在降低感染艾滋病毒风险方面具有有效性。作为在美国黑人和拉丁裔男男性行为者中提高PrEP知晓率的预防信息开发工作的一部分,我们开展了形成性定性研究,以探索受众对PrEP信息概念的反应和接受度。2013年,来自芝加哥、劳德代尔堡和堪萨斯城的48名黑人及42名拉丁裔(研究总样本 = 90)艾滋病毒血清学状态各异的男男性行为者参与了个人访谈或焦点小组讨论。这些男性通过网络及各城市的社区组织招募而来。我们就两条PrEP信息草稿的可理解性、可信度及相关性征求了反馈意见。这些信息包含了iPrEx试验的疗效评估数据,iPrEx是一项三期临床试验,旨在确定抗逆转录病毒药物替诺福韦/恩曲他滨富马酸二吡呋酯(商品名为Truvada)能否安全有效地预防男男性行为者及跨性别女性通过性行为感染艾滋病毒。在参与者同意的情况下,访谈和焦点小组讨论进行了录音及转录。然后使用定性描述方法对数据进行总结和分析。大多数男性对PrEP并不熟悉。研究表明,需要提供更多关于该药物及确立疗效的临床试验的信息,以增强信息的合理性和相关性。参与者试图基于自己对疗效数据的理解形成对PrEP的看法。然而,对临床试验受试者不坚持用药情况以及个体风险与平均风险的混淆限制了对这些信息的理解。主题重叠表明,信息可信度与参与者从PrEP疗效数据中获取意义的能力相关。尽管担心其他男男性行为者会将这些信息解读为服用PrEP时无需使用避孕套,但参与者自己主要将PrEP理解为避孕套的补充而非替代品。基于他们服用抗逆转录病毒药物的经历,艾滋病毒呈阳性的男性认为使用避孕套比PrEP是更可行的艾滋病毒预防方式。参与者的回答表明,更多关于PrEP及临床试验的信息将支持PrEP及整个信息的合理性。这些细节可能会增强对PrEP概念的可信度,并加强对疗效结果有效性的信心。
