To analyze the construct validity and the internal consistency of the 12-item Bem Sex Role Inventory (BSRI-12) questionnaire and to study the association between gender stereotypes and sexual risk practices in men who have sex with men (MSM).
Cross-sectional study of 601 MSM who voluntarily and anonymously responded to an online survey on risk practices and gender stereotypes. The BSRI-12 was used to obtain gender stereotypes (masculine, feminine, undifferentiated and androgynous). For data analysis, exploratory factor analysis (EFA) of the BSRI-12 and logistic regression were performed.
Two main factors (Cronbach alpha 0.95 and 0.81) were obtained from the EFA. Using the androgynous roles as the reference category, we found lower odds of engaging in unprotected anal intercourse (UAI) among those who endorse feminine roles (OR: 0.53; 95%CI: 0.29-0.95). Endorsing masculine roles with alcohol consumption (OR: 1.92; 95%CI: 1.15-3.20) or the undifferentiated when not knowing the partner's serological status (OR: 1.55; 95%CI: 1.02-2.35) were associated with higher odds of UAI compared to those endorsing the androgynous roles. Undifferentiated participants also perform receptive UAI using poppers (OR: 2.19; 95%CI: 1.24-3.87), and insertive UAI not knowing the serological status of the sexual partner (OR: 1.69; 95%CI: 1.04-2.76) compared to androgynous participants.
The BSRI is a valid and consistent instrument for identifying gender stereotypes in MSM. A greater proportion of participants within the undifferentiated and the masculine category engage in risk practices with the influence of substance consumption and unawareness of their sexual partner's serological status. The information obtained may be useful to define intervention and prevention programs.
分析12项贝姆性别角色量表（BSRI - 12）问卷的结构效度和内部一致性，并研究男男性行为者（MSM）的性别刻板印象与性风险行为之间的关联。
对601名MSM进行横断面研究，这些人自愿且匿名地对一项关于风险行为和性别刻板印象的在线调查做出回应。使用BSRI - 12来获取性别刻板印象（男性化、女性化、未分化和双性化）。进行数据分析时，对BSRI - 12进行探索性因素分析（EFA）并进行逻辑回归。
通过EFA获得了两个主要因素（克朗巴哈系数分别为0.95和0.81）。以双性化角色作为参照类别，我们发现认同女性化角色的人进行无保护肛交（UAI）的几率较低（比值比：0.53；95%置信区间：0.29 - 0.95）。与认同双性化角色的人相比，认同男性化角色且饮酒（比值比：1.92；95%置信区间：1.15 - 3.20）或在不了解性伴侣血清学状态时认同未分化角色（比值比：1.55；95%置信区间：1.02 - 2.35）与更高的UAI几率相关。与双性化参与者相比，未分化参与者在使用催情药时进行接受方UAI的几率也更高（比值比：2.19；95%置信区间：1.24 - 3.87），且在不了解性伴侣血清学状态时进行插入方UAI的几率也更高（比值比：1.69；95%置信区间：1.04 - 2.76）。
BSRI是识别MSM性别刻板印象的有效且一致的工具。在未分化和男性化类别中，更大比例的参与者在物质消费和不了解性伴侣血清学状态的影响下从事风险行为。所获得的信息可能有助于确定干预和预防项目。
