This study investigated the effects of sexual arousal and sexual partner characteristics as determinants of HIV+ men who have sex with men's (MSM) intentions to engage in unprotected sex.
In a computer-based controlled experiment, 67 HIV+ MSM underwent a sexual arousal manipulation and indicated their intentions to engage in unprotected sex with hypothetical partners who differed in terms of HIV serostatus, physical attractiveness, relationship type, and preference for condom use.
Computer-delivered questions assessed HIV+ MSM's intentions to engage in various sexual acts with each hypothetical partner.
As predicted, sexually aroused HIV+ MSM indicated stronger intentions to engage in unprotected sex than nonaroused HIV+ MSM; and having a partner who was attractive, HIV+, long term, or who preferred not to use condoms, also led to riskier intentions. Several significant interactions among these factors were found, which were generally consistent with predictions and with theory and research on cognitive processing and decision making.
These findings have implications for understanding risky sexual behavior among HIV+ individuals and for the development of interventions to reduce this risk.
本研究调查了性唤起和性伴侣特征作为感染艾滋病毒的男男性行为者（MSM）进行无保护性行为意愿的决定因素所产生的影响。
在一项基于计算机的对照实验中，67名感染艾滋病毒的男男性行为者接受了性唤起操控，并表明了他们与在艾滋病毒血清状况、身体吸引力、关系类型以及使用避孕套偏好方面存在差异的假设性伴侣进行无保护性行为的意愿。
通过计算机提出的问题评估感染艾滋病毒的男男性行为者与每个假设性伴侣进行各种性行为的意愿。
正如预测的那样，性唤起的感染艾滋病毒的男男性行为者比未唤起的感染艾滋病毒的男男性行为者表现出更强的进行无保护性行为的意愿；并且有一个有吸引力、感染艾滋病毒、长期关系的伴侣，或者一个不喜欢使用避孕套的伴侣，也会导致更具风险的意愿。在这些因素之间发现了几个显著的相互作用，这总体上与预测以及关于认知加工和决策的理论及研究一致。
这些发现对于理解感染艾滋病毒个体中的危险性行为以及开发降低这种风险的干预措施具有启示意义。
