In medication adherence-promotion trials, participants in the intervention arm are often cognizant of the researcher's aim to improve adherence; this may lead to their inflating reports of their own adherence compared to control arm participants. Using data from 1,247 HIV-positive participants across eight U.S. Studies in the Multi-site Adherence Collaboration on HIV (MACH14) collaboration, we evaluated the validity of self-reported adherence by examining whether its association with two more objective outcomes [1], electronically monitored adherence and [2] viral load, varied by study arm. After adjusting for potential confounders, there was no evidence of greater overestimation of self-reported adherence among intervention arm participants, supporting its potential as a trial outcome indicator.
在促进药物依从性的试验中,干预组的参与者通常知晓研究人员旨在提高依从性的目的;与对照组参与者相比,这可能导致他们夸大自己的依从性报告。利用来自美国八项关于HIV的多中心依从性协作研究(MACH14)中1247名HIV阳性参与者的数据,我们通过检查自我报告的依从性与另外两个更客观的结果[1]电子监测的依从性和[2]病毒载量之间的关联是否因研究组而异,来评估自我报告依从性的有效性。在对潜在混杂因素进行调整后,没有证据表明干预组参与者对自我报告依从性的高估更严重,这支持了其作为试验结果指标的潜力。
