The objective of this study is to assess (1) whether beliefs about trust and condom use affect sexual risk behaviour, and (2) if beliefs about trust and condom use impact sexual risk behaviour directly or if this relationship is mediated by other determinants. The Information-Motivation-Behavioural Skills model was used as a framework for the mediation analysis. A diverse cohort of three hundred 18-40 year old men who have sex with men (MSM) residing in Pretoria, South Africa, were recruited and surveyed for this project. Findings indicate that men who report a high frequency of past unprotected anal intercourse are more likely to believe that it is not necessary to use condoms with a trusted or steady partner regardless of their current partnership status. This fallacy of intimacy appears to affect sexual risk behaviour through intentions and attitudes regarding safer sex practices. Based on these findings, we recommend that more attention be given in gaining a better understanding of how beliefs about trust and condom use are formed and how they can be changed among MSM in South Africa.
(1) 信任和使用安全套的信念是否会影响性行为风险；(2) 信任和使用安全套的信念对性行为风险的影响是直接的，还是通过其他决定因素间接产生影响。本研究采用信息-动机-行为技能模型作为中介分析的框架。我们招募了居住在南非比勒陀利亚的 300 名 18-40 岁的男男性行为者（MSM）参与了这项研究。研究结果表明，报告过去有过无保护肛交的男性更有可能认为，与可信任或稳定的伴侣发生性行为时无需使用安全套，而不论其当前的伴侣关系状况如何。这种亲密关系的错误观念似乎通过对安全性行为实践的意图和态度影响性行为风险。基于这些发现，我们建议更多地关注如何更好地理解南非 MSM 中对信任和使用安全套的信念是如何形成的，以及如何改变这些信念。
