Combining multiple biomedical and behavioral HIV prevention approaches is a priority for at-risk populations such as men who have sex with men (MSM), and it is essential to understand how receiving messages about multiple approaches impacts attitudes and intentions for their use. We examined whether receiving combinations of different HIV prevention messages produced differences in perceived benefits and costs of condom use, and in intentions to use condoms and biomedical prevention approaches. MSM (N = 803) were recruited online and were randomly assigned to view informational messages about one, two, or four of the following prevention options: pre-exposure prophylaxis (PrEP), non-occupational post-exposure prophylaxis (nPEP), rectal microbicides, and condoms. The number of HIV prevention messages did not produce differential attitudes and intentions regarding condoms, nor did it produce changes in attitudes towards unprotected sex. Receiving multiple messages was associated with greater intentions to use PrEP and nPEP, but not rectal microbicides.
将多种生物医学和行为学的艾滋病毒预防方法结合起来，是男男性行为者（MSM）等高危人群的首要任务，了解接收关于多种方法的信息如何影响其使用这些方法的态度和意愿至关重要。我们研究了接收不同艾滋病毒预防信息的组合是否会在使用避孕套的感知益处和成本，以及使用避孕套和生物医学预防方法的意愿方面产生差异。通过网络招募了男男性行为者（N = 803），并将他们随机分配观看关于以下一种、两种或四种预防选项的信息性信息：暴露前预防（PrEP）、非职业性暴露后预防（nPEP）、直肠杀菌剂和避孕套。艾滋病毒预防信息的数量并未在对避孕套的态度和意愿上产生差异，对无保护性行为的态度也未产生变化。接收多条信息与使用PrEP和nPEP的意愿增强有关，但与直肠杀菌剂无关。
