Little research has examined predictors of condom intention within concurrent partnerships. This study examined predictors of intention among 259 male African-American crack smokers with multiple partners. Each participant reported personal condom intention at next sex, condom use self-efficacy, responsibility and outcome expectances for himself and his perceptions for his last two sex partners. Stepwise logistic regressions showed that for both partners one and two, condom use at last sex and personal responsibility for condom use were predictors of intention to use condoms at next sex. Perceived partner responsibility was an additional positive predictor with Partner 2. Hierarchical generalized linear model analyses showed that positive intention was associated negatively with perceived partner responsibility and intimacy, while positively related to situational self-efficacy. Personal responsibility interacted with intimacy such that only men who indicated the highest levels of intimacy were more likely to intend to use condoms. Overall, the findings in this study support the need for examining additional social cognitive constructs that capture the interpersonal aspects of sexual relationships such as personal and perceived responsibility, intimacy and how beliefs may change between multiple partners and across time. Finally, the differences in the valence of perceived partner responsibility across analyses and the interaction of personal responsibility with intimacy suggest the need for studies that include measure of power within the relationship.
很少有研究探讨同时存在多个性伴侣关系中使用避孕套意愿的预测因素。本研究调查了259名有多个性伴侣的非裔美国男性可卡因吸食者的使用避孕套意愿的预测因素。每位参与者报告了其下次性行为时个人使用避孕套的意愿、使用避孕套的自我效能感、对自己以及对其最近两个性伴侣的责任和结果预期。逐步逻辑回归分析表明，对于性伴侣1和性伴侣2，最近一次性行为时使用避孕套的情况以及个人对使用避孕套的责任是下次性行为时使用避孕套意愿的预测因素。对于性伴侣2，感知到的伴侣责任是另一个积极的预测因素。分层广义线性模型分析表明，积极意愿与感知到的伴侣责任和亲密程度呈负相关，而与情境自我效能感呈正相关。个人责任与亲密程度存在交互作用，只有那些表示亲密程度最高的男性才更有可能打算使用避孕套。总体而言，本研究的结果支持有必要研究更多的社会认知结构，这些结构能够捕捉性关系中的人际方面，如个人责任和感知到的责任、亲密程度以及在多个性伴侣之间和不同时间信念可能如何变化。最后，在不同分析中感知到的伴侣责任的效价差异以及个人责任与亲密程度的交互作用表明，有必要开展纳入关系中权力衡量指标的研究。
