BACKGROUND
Valid and reliable instruments are needed to measure the multiple dimensions of perceived risk. The Perceived Risk of HIV Scale is an 8-item measure that assesses how people think and feel about their risk of infection. We set out to perform a cross-cultural adaptation of the scale to Brazilian Portuguese among key populations (gay, bisexual and other men who have sex with men and transgender/non-binary) and other populations (cisgender heterosexual men and cisgender women).
METHODS
Methodological study with cross-sectional design conducted online during October/2019 (key populations [sample 1] and other populations) and February-March/2020 (key populations not on pre-exposure prophylaxis [sample 2]). Cross-cultural adaptation of the Perceived Risk of HIV Scale followed Beaton et al. 2000 guidelines and included confirmatory factor analysis, differential item functioning (DIF) using the Multiple-Indicator Multiple-Cause model, and concurrent validity to verify if younger individuals, those ever testing for HIV, and engaging in high-risk behaviors had higher scores on the scale.
RESULTS
4342 participants from key populations (sample 1 = 235; sample 2 = 4107) and 155 participants from other populations completed the measure. We confirmed the single-factor structure of the original measure (fit indices for sample 1 plus other populations: CFI = 0.98, TLI = 0.98, RMSEA = 0.07; sample 2 plus other populations: CFI = 0.97, TLI = 0.95, RMSEA = 0.09). For the comparisons between key populations and other populations, three items (item 2: "I worry about getting infected with HIV", item 4: "I am sure I will not get infected with HIV", and item 8: "Getting HIV is something I have") exhibited statistically significant DIF. Items 2 and 8 were endorsed at higher levels by key populations and item 4 by other populations. However, the effect of DIF on overall scores was negligible (0.10 and 0.02 standard deviations for the models with other populations plus sample 1 and 2, respectively). Those ever testing for HIV scored higher than those who never tested (p < .001); among key populations, those engaging in high-risk behaviors scored higher than those reporting low-risk.
CONCLUSION
The Perceived Risk of HIV Scale can be used among key populations and other populations from Brazil.
背景
需要有效的和可靠的工具来测量感知风险的多个维度。感知 HIV 风险量表是一个 8 项的衡量指标，评估人们对感染风险的想法和感受。我们着手将该量表从英文翻译成巴西葡萄牙文，用于重点人群（男同性恋、双性恋和其他与男性发生性关系的男性以及跨性别/非二元性别者）和其他人群（顺性别异性恋男性和顺性别女性）。
方法
这是一项具有横断面设计的方法学研究，于 2019 年 10 月（重点人群[样本 1]和其他人群）和 2020 年 2 月至 3 月（未使用暴露前预防的重点人群[样本 2]）期间在网上进行。根据 Beaton 等人的 2000 年指南进行了感知 HIV 风险量表的跨文化适应性调整，包括验证性因素分析、使用多指标多原因模型的差异项目功能（DIF）以及同时有效性，以验证年轻个体、曾经接受过 HIV 检测的个体和从事高风险行为的个体是否在量表上得分更高。
结果
共有 4342 名重点人群（样本 1=235；样本 2=4107）和 155 名其他人群参与者完成了该测量。我们证实了原始测量的单因素结构（样本 1 加其他人群的拟合指数：CFI=0.98，TLI=0.98，RMSEA=0.07；样本 2 加其他人群：CFI=0.97，TLI=0.95，RMSEA=0.09）。对于重点人群与其他人群之间的比较，有三个项目（项目 2：“我担心感染 HIV”，项目 4：“我确定我不会感染 HIV”，和项目 8：“感染 HIV 是我可能会发生的事情”）表现出统计学上显著的差异项目功能（DIF）。项目 2 和 8 被重点人群更高地认可，而项目 4 被其他人群认可。然而，DIF 对总体分数的影响可以忽略不计（对于加有其他人群的样本 1 和 2 的模型，分别为 0.10 和 0.02 个标准差）。曾经接受过 HIV 检测的人比从未接受过检测的人得分更高（p<0.001）；在重点人群中，从事高风险行为的人比报告低风险的人得分更高。
结论
感知 HIV 风险量表可用于巴西的重点人群和其他人群。
