Abstract

Accurate assessment of general HIV and pre-exposure prophylaxis (PrEP) knowledge is essential for evaluating contemporary prevention efforts. This study examined the psychometric properties of a revised HIV and PrEP knowledge instrument for young sexual and gender minority (SGM) men. Data were collected from 1,519 participants (ages 17-29) via an online survey. Of the original 31 items, 7 were removed based on item analysis, and Exploratory Factor Analysis (EFA) was conducted on the remaining 24 items. EFA supported a two-factor structure-18 items assessing general HIV knowledge and 6 assessing PrEP knowledge-with acceptable model fit (RMSEA = 0.06) and strong factor loadings (0.32). The instrument demonstrated measurement invariance across major racial/ethnic groups, moderate to strong item-total correlations (≥0.30), and acceptable internal consistency for both subscales. Findings validate this 24-item, two-factor instrument as a reliable tool for assessing HIV and PrEP knowledge among SGM men.

经修订的SGM男性HIV知识评估工具的心理测量学评价。

准确评估一般艾滋病毒和暴露前预防知识对于评估当代预防工作至关重要。本研究检验了修订后的艾滋病毒和PrEP知识工具对年轻性和性别少数（SGM）男性的心理测量特性。数据通过在线调查从1519名参与者（17-29岁）中收集。原31项中，经项目分析剔除7项，对剩余24项进行探索性因子分析（EFA）。全民教育支持一个双因素结构——18个项目评估普通HIV知识，6个项目评估PrEP知识——具有可接受的模型拟合（RMSEA = 0.06）和强因素负荷（0.32）。该工具显示了主要种族/民族群体的测量不变性，中等至强烈的项目-总量相关性（≥0.30），两个分量表的内部一致性可接受。研究结果证实，这一24项双因素仪器是评估男性男性中HIV和PrEP知识的可靠工具。
