This study aimed to examine the relationship between anticipated stigma and medication adherence as well as the mechanistic roles of medication support and ART self-efficacy. Data were derived from the baseline assessment of a prospective cohort study in Guangxi, China. A total of 1198 PLWH were recruited and assessed on their sociodemographic characteristics, medication adherence, anticipated stigma, medication support, and ART self-efficacy. Path analysis was used to examine the direct effect from anticipated stigma to medication adherence and indirect effects through medication support and ART self-efficacy. Path model revealed that the indirect effect from anticipated stigma to medication adherence was statistically significant while the direct effect was not significant. Anticipated stigma could influence medication adherence through ART self-efficacy but not through medication support. The serial mediating effect of medication support and ART self-efficacy on the relationship between anticipated stigma and medication adherence was significant. Anticipated stigma affects medication adherence among PLWH through its adverse impact on medication support and ART self-efficacy. Tailored interventions promoting medication support and ART self-efficacy may alleviate the negative influence of anticipated stigma on medication adherence among PLWH. Additionally, policy efforts aiming to reduce stigma against PLWH and increasing medication support are warranted to improve medication adherence among PLWH.
本研究旨在探讨预期污名与服药依从性之间的关系,以及药物支持和抗逆转录病毒治疗自我效能感的作用机制。数据来源于中国广西一项前瞻性队列研究的基线评估。共招募了1198名艾滋病毒感染者,并对他们的社会人口学特征、服药依从性、预期污名、药物支持和抗逆转录病毒治疗自我效能感进行了评估。采用路径分析来检验预期污名对服药依从性的直接效应,以及通过药物支持和抗逆转录病毒治疗自我效能感的间接效应。路径模型显示,预期污名对服药依从性的间接效应具有统计学意义,而直接效应不显著。预期污名可通过抗逆转录病毒治疗自我效能感影响服药依从性,但不能通过药物支持。药物支持和抗逆转录病毒治疗自我效能感在预期污名与服药依从性之间的系列中介效应显著。预期污名通过对药物支持和抗逆转录病毒治疗自我效能感的不利影响,影响艾滋病毒感染者的服药依从性。针对性地促进药物支持和抗逆转录病毒治疗自我效能感的干预措施,可能会减轻预期污名对艾滋病毒感染者服药依从性的负面影响。此外,有必要通过政策努力减少对艾滋病毒感染者的污名,并增加药物支持,以提高艾滋病毒感染者的服药依从性。
