Background: Women comprise over one-quarter of new HIV infections in the United States. A deeper understanding of the factors associated with women’s sexual risk taking behavior is needed to design more effective HIV prevention interventions. Prior research has demonstrated a strong relationship between self-efficacy for condom use and use of condoms. Less is known about the factors that influence self-efficacy for condom use. This study identified factors associated with low self-efficacy for condom use among women at risk of HIV infection utilizing data from the UNITY study which enrolled sexually active, non-injection drug using adult women in New York City.

Methods: At baseline, women provided information via ACASI on a variety of potential correlates with self-efficacy for condom use by partner type. Contingency tables and exact tests compared the proportions of women reporting low self-efficacy for condom use with each partner type by socio-demographics, sexual behaviors, experience of violence, drug and alcohol use, depression, condom attitudes, relationship power, and partner perceptions. Logistic regression models were then constructed using backward selection to identify correlates of low self-efficacy.

Results: Among women with a steady partner (n=277), factors associated with low self-efficacy in the logistic regression model included spending 1+ overnight in detox (OR 0.29, 95% CI 0.11-0.77), childhood abuse (OR 4.51, 95% CI 2.12-9.59), lower ability to resist unsafe sex (OR 3.30, 95% CI 1.53-7.11), report of anal sex with a steady partner (OR 3.40, 95% CI 1.69-6.82), and less favorable attitudes toward condoms (OR 2.91, 95% CI 1.33-6.36). Among women with a casual partner (n=304), current employment (OR 0.24, 95% CI 0.07-0.87), spending 1+ overnight in a shelter (OR 2.24, 95% CI 1.32-3.80), report of anal sex with a casual partner (OR 3.00, 95% CI 1.65-5.46), and poor condom communication skills (OR 4.94, 95% CI 2.29-10.64) were associated with low self-efficacy.

Conclusion: In keeping with prior research on condom use, factors associated with low self-efficacy for condom use varied by partner type with the exception of anal sex. These findings suggest areas to target in future research and when crafting HIV prevention interventions.
