HIV prevention efforts promote the use of condoms to prevent the spread of HIV and other STDs. Thus, a woman's agency to practice healthy sexual behaviors necessarily involves negotiation with another person. This poses unique challenges for women who have limited power in relationships. The current study explores how the experience of intimate partner violence (IPV) impacts a woman's confidence in her ability to negotiate condom use with a sexual partner (i.e., condom use self-efficacy), using data from incarcerated females in three states, who were interviewed just prior to release back into the community. The "direct effect" of experiencing IPV as an adult, controlling for other risk factors, on condom use self-efficacy has not previously been empirically tested. Results show that IPV experiences among women significantly decreases their confidence in negotiating condom use with a partner, putting them at a higher risk of HIV infection than women who do not report having recently experienced IPV.
