Studies show that having sex with multiple partners increases the risk of acquiring and transmitting sexually transmitted diseases, including HIV. The present article reports prospective predictors of having multiple sexual partners among 505 African American men in Philadelphia who have sex with men (MSM) who participated in an intervention trial and attended a 6-month follow-up. Participants completed audio computer-assisted surveys of demographics, sexual behavior, and Reasoned Action Approach and Social Cognitive Theory mediators concerning multiple partners. We analyzed the incidence of self-reported multiple partners at the 6-month follow-up, controlling for treatment condition and baseline levels of the theoretical variables. The odds of having multiple partners decreased with increasing age (p < .03). Participants who said they were HIV positive had lower odds of having multiple partners (p < .009). The more pride participants reported in their identities as black or African American men, the lower the odds that they reported having multiple partners (p < .02). Adverse outcome expectancies accruing to multiple partners fully mediated the effect of black pride and partially mediated the effects of age on the odds of having multiple partners. Modifiable factors such as perceived negative outcome expectancies regarding having multiple sex partners should be addressed in designing interventions and prevention programs with the goal of decreasing the number of sexual partners among African American MSM.
研究表明，与多个性伴侣发生性行为会增加感染和传播性传播疾病（包括 HIV）的风险。本文报告了在费城与男性发生性关系的 505 名非裔美国男性中，进行了一项干预试验并参加了 6 个月随访，其中有多个性伴侣的前瞻性预测因素。参与者完成了关于人口统计学、性行为以及有关多个伴侣的理性行动方法和社会认知理论中介因素的音频计算机辅助调查。我们分析了在 6 个月随访时自我报告的多个伴侣的发生率，控制了治疗条件和理论变量的基线水平。拥有多个伴侣的可能性随着年龄的增加而降低（p<.03）。报告自己 HIV 阳性的参与者拥有多个伴侣的可能性较低（p<.009）。参与者对自己作为黑人或非裔美国男性的身份感到自豪的程度越高，他们报告拥有多个伴侣的可能性就越低（p<.02）。多个伴侣的不良后果预期完全中介了黑人自豪感的影响，部分中介了年龄对拥有多个伴侣的可能性的影响。应该在设计干预措施和预防计划时解决与拥有多个性伴侣相关的可改变因素，如对多个性伴侣的不良后果预期，以减少非裔美国男男性行为者的性伴侣数量。
