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.
