The goal of this study was to develop and evaluate psychometric properties of the PrEP Sexual Expectancies Scale (PSEXS). The PSEXS represents a range of expectations for how PrEP use will affect one's sexual experience. The scale was developed to understand perceived reinforcements of PrEP use among men who have sex with men (MSM), including sexual risk-taking. The study builds upon Expectancy Theory to develop a measure of sex-related PrEP expectancies with a representative sample of 1155 MSM participants from Ukraine and 408 MSM participants from the U.S. Expectancy items represented two domains: increased sexual risk-taking and enhancement of sexual experience. Confirmatory analyses showed that a two-factor model provided a good fit to the data. The PSEXS scale had a high internal reliability in both samples (Ukraine α = 0.88, U.S. α = 0.83), and the identified factor structure explains a large amount of variance in both samples. Recent studies suggest that expectations of intimacy and better sexual experience can be a significant deciding factor for PrEP uptake. The PSEXS provides researchers with a useful measure for examining MSM’s expectancy beliefs about the impact of PrEP use on their sexual life.

PrEP 性期望 (PSEXS) 量表的开发和心理测量评估

本研究的目的是开发和评估 PrEP 性期望量表 (PSEXS) 的心理测量特性。PSEXS 代表了对 PrEP 使用将如何影响一个人的性体验的一系列期望。该量表旨在了解男男性行为者 (MSM) 中感知到的 PrEP 使用增强,包括性冒险。该研究建立在期望理论的基础上,以来自乌克兰的 1155 名 MSM 参与者和来自美国的 408 名 MSM 参与者的代表性样本来开发与性相关的 PrEP 期望的衡量标准。期望项目代表两个领域:增加性冒险和增强性体验。验证性分析表明,双因素模型很好地拟合了数据。PSEXS 量表在两个样本中都具有很高的内部信度(乌克兰 α = 0.88,美国 α = 0。83),并且确定的因子结构解释了两个样本中的大量方差。最近的研究表明,对亲密关系和更好的性体验的期望可能是 PrEP 吸收的重要决定因素。PSEXS 为研究人员提供了一种有用的测量方法,用于检查 MSM 对 PrEP 使用对其性生活影响的预期信念。
