Based on the social cognitive theory, this study aimed to examine the mediating role of outcome expectations in the relationship between physician-patient trust and medication adherence among older adults living with HIV, so as to provide evidence for developing effective intervention strategies.
A cross-sectional survey was conducted from July to October 2024 in six districts (counties, county-level cites) of Xiangyang City, using a stratified random sampling method. Data were collected using the Morisky Medication Adherence Scale, the Physician-Patient Trust Scale, and the Outcome Expectations Scale. Hierarchical regression analysis was employed to test the mediating effect of outcome expectations.
A total of 203 valid samples were obtained. The analysis revealed that factors such as gender, place of residence, average monthly household income, occupational status, alcohol consumption, and adverse drug reactions had significant effects on medication adherence (P<0.05). Physician-patient trust and outcome expectations were significantly positively correlated with antiretroviral medication adherence (r=0.37, P<0.001). Outcome expectations played a partial mediating role between physician-patient trust and medication adherence, with a mediation effect of 10%.
Physician-patient trust can significantly improve medication adherence in older adults with HIV by enhancing their positive outcome expectations. It is recommended that antiretroviral therapy programs for this population focus on strengthening patients’ positive perceptions of treatment benefits to improve their medication adherence.
