The study examined potential psychosocial determinants of male condom use in steady heterosexual relationships among Somali and Ethiopian immigrants in Minnesota in two sequential phases: the elicitation (Phase I) and cross-sectional quantitative studies (Phase II). Information from Phase I was used to develop the instrument for Phase II. Study participants who self-identified as Somali and Ethiopian immigrants (n = 205) responded to questions on demographic characteristics, attitudes (affective and instrumental), norms (subject and descriptive), perceived behavioral control, self-efficacy, and intention to use male condoms. Hierarchical regression models were used to assess the relationship between the main independent variables (attitude norms, perceived behavioral control, and self-efficacy, and the dependent variable, the intention to use male condoms. Overall, participants showed low intention and slightly favorable (affective and instrumental) attitudes toward condom use; had experienced weak, but positive social influence as measured by injunctive and descriptive norms. Moreover, study participants had shown slight perceived behavioral control, but had fairly moderate positive self-efficacy. The Theory of Planned Behavior was moderately effective in predicting condom use; however, the Integrated Behavioral Model, explained nearly 40% of the variations in the intention to use male condoms. Among men, self-efficacy had the strongest influence (β = .44, p < .001) on behavioral intention. Among women, descriptive norms (β = .22,p < .05) exerted the strongest effect (model 3). Improving self-efficacy, specifically, among older men, and fostering desirable normative influence among women, are suggested as main components of public health interventions to promote condom use among Somali and Ethiopian immigrants.
