Factors of interpersonal communication and behavioral health on medication self-efficacy and medication adherence.
Despite devastating effects on health outcomes and disease progression, many people living with HIV (PLWH) are non-adherent to their medications. Medication self-efficacy is a pivotal factor in medication adherence, yet its formation and relationship with other factors are understudied. This study examines a model that considers the role of three communicative factors (patient-provider communication, social support, and social undermining) and two behavioral health factors (depression and alcohol abuse) and medication self-efficacy impacting medication adherence. Methods included a cross-sectional design using a survey questionnaire of 344 PLWH. Findings indicated that 25% of variance in medication adherence can be explained by a mediation model where depression (B = -.18) and provider-patient communication (B = .21) affect medication self-efficacy, which in turn impacts medication adherence (B = .64). Other variables, including demographics, did not add any explanatory power. These findings demonstrate the complex nature of medication adherence and the formation of medication self-efficacy.
