Adherence to antiretroviral therapy (ART) is integral to the successful treatment of HIV infection. Research has indicated that HIV-infected Latinos may have difficulty adhering to ART. While studies have demonstrated strong relationships between numerous psychosocial factors and ART adherence, no research has examined if cultural factors are also involved in ART adherence among Latinos. Our study examined the relationship between acculturation to mainstream U.S. culture, bicultural self-efficacy, and ART adherence among HIV-infected Puerto Rican adults living in the United States. Participants with ≥ 95% adherence scored higher on U.S.- and Latino-involvement acculturation scales and on a measure of bicultural self-efficacy compared to those with suboptimal adherence. Among bicultural HIV-infected Puerto Ricans, both acculturation and self-efficacy to navigate between cultures were positively related to adherence. Understanding the role of an individual's sociocultural experience may help elucidate why HIV-infected Latinos have difficulties achieving optimal ART adherence and improve ART adherence interventions.
