目的：调查女性使用阴道杀微生物剂来减少/预防艾滋病毒感染的意愿，采用基于个人、行为和社会性背景的措施。设计：一项横断面研究，招募了 2004 年 10 月至 2005 年 7 月期间美国 18-55 岁拉丁裔、非裔美国人和白人女性样本（N = 531）。主要结果指标：使用杀菌剂的意愿以及个人和环境相关变量（例如人口统计、关系状况）。结果：探索性和验证性因素分析支持一维、8 项量表，具有较高的内部一致性 (alpha = .91)。拉丁裔 (n = 166)、非裔美国人 (n = 193) 和白人子样本 (n = 172) 内的亚组分析也支持具有强内部效度和高可靠性的一维量表。作为背景因素的种族/族裔、女性使用预防产品的历史以及性伴侣的性质可以预测使用杀菌剂的意愿（R = .41）。也就是说，使用安全套频率较高、有杀精剂使用史和非主要性伴侣的女性的使用杀菌剂意愿量表得分较高，而白人女性的预测得分较低。结论：使用杀菌剂意愿量表是第一个经过心理测量验证的与杀菌剂可接受性相关因素的衡量标准。制定和实施经过心理测量验证和情境化的杀菌剂可接受性措施，以了解杀菌剂使用者和使用情况，对于临床试验和未来的干预研究都至关重要。
Objective: To investigate women's willingness to use vaginal microbicides to reduce/prevent HIV infection, using measures grounded in the individual, behavioral, and social contexts of sex. Design: A cross-sectional study that enrolled a sample (N = 531) of 18-55 year old Latina, African-American, and White women in the U.S. between October, 2004, and July, 2005. Main Outcome Measures: Willingness to use microbicides and individual- and context-related variables (e.g., demographics, relationship status). Results: Exploratory and confirmatory factor analyses supported a one-dimensional, 8-item scale, with high internal consistency (alpha = .91). Subgroup analyses within the Latina (n = 166), African-American (n = 193), and White sub-samples (n = 172) also supported a unidimensional scale with strong internal validity and high reliability. Race/ethnicity as a contextual factor, a woman's history of using prevention products, and the nature of the sexual partnership were predictive of willingness to use microbicides (R = .41). That is, women with greater frequencies of condom use, a history of spermicide use, and non-main sexual partners had higher predicted Willingness to Use Microbicides scale scores, while White women had lower predicted scores. Conclusion: The Willingness to Use Microbicides scale serves as the first psychometrically validated measure of factors related to microbicide acceptability. Developing and implementing psychometrically validated and contextualized microbicide acceptability measures, in an effort to understand microbicide users and circumstances of use, is crucial to both clinical trials and future intervention studies.
