HIV risk perception is a known determinant of HIV prevention behaviors among vulnerable populations. Lesser known is the combined influence of risk perception and efficacy beliefs on PrEP use. We examined the associations between levels of risk perception and strength of efficacy beliefs on intent to use PrEP in a sample of adult Black and Latina women. Guided by the risk perception attitudes (RPA) framework, we used cluster analysis to identify four interpretable groups. We ran analysis of covariance models to determine the relationship between membership in the RPA framework groups and intention to use PrEP. Among the 908 women, the mean age was 29.9 years and participants were Latina (69.4%) and Black (25.6%). Results of the analysis show that women with low perception of HIV risk and strong efficacy beliefs had significantly less intent to use PrEP than women with high risk perception and weak efficacy beliefs.

HIV风险感知，性健康功效和妇女使用PrEP的意图之间的关联：风险感知态度框架的应用。

HIV风险感知是易感人群中HIV预防行为的已知决定因素。鲜为人知的是风险感知和功效信念对PrEP使用的综合影响。我们在成年的黑人和拉丁裔女性样本中研究了风险感知水平与意图使用PrEP的功效信念强度之间的关联。在风险感知态度（RPA）框架的指导下，我们使用聚类分析来识别四个可解释的群体。我们对协方差模型进行了分析，以确定RPA框架组中的成员资格与使用PrEP的意图之间的关系。在908名妇女中，平均年龄为29.9岁，参加者为拉丁裔（69.4％）和黑人（25.6％）。
