研究人员越来越多地使用间接线人来验证主要研究对象提供的报告。我们在一项研究中评估了大学生附带举报人的效用，该研究结合生物标志物来验证学生最近饮酒行为的报告。方法随机选择美国中西部一所大学的学生进行研究，他们提供了90天时间线随访数据、用于乙基葡糖苷（EtG）检测的头发和指甲标本，以及熟悉其饮酒行为的间接（朋友或同龄人）举举人的信息。我们比较了72名学生的近期饮酒的总结测量与附带的线人报告，这些学生被选中参加附带的验证过程，他们有完整的测量。采用Kappa、加权Kappa和McNemar试验来评价一致性水平。我们在EtG调查结果的背景下比较了每个信息提供者所表明的使用水平。我们还比较了受访者和间接报告中关于酗酒的直接EtG测试结果。结果学生参与者提供的报告与其附带举报人之间存在相当大的重叠。在etg信息分析的背景下，除了研究对象提供的信息外，抵押品很少提供关于重度使用的新信息。结论间接举报人在随机选取的大学生重度饮酒的非临床研究中应用有限。
IntroductionResearchers have increasingly used collateral informants to validate the reports provided by primary research subjects. We assessed the utility of collateral informants for college students in a study that incorporates biomarkers to validate student reports of recent drinking behavior.MethodsStudents from a Midwestern university were randomly selected for a study in which they provided 90-day Timeline Followback data, hair and fingernail specimens for ethylglucuronide (EtG) testing, and information about collateral (friends or peers) informants who were familiar with their drinking behavior. We compared summary measures of recent drinking to collateral informant reports for the subset of 72 students who were selected to participate in the collateral validation process who had complete measures. Kappa, weighted kappa, and McNemar tests were performed to evaluate levels of agreement. We compared levels of use indicated by each informant within the context of EtG findings. We also compared respondent and collateral reports with respect to heavy drinking directly to EtG test results.ResultsThere was considerable overlap between the reports provided by the student participants and their collateral informants. Within the context of EtG-informed analyses, collaterals rarely provided new information about heavy use beyond that provided by the study subjects.ConclusionsCollateral informants have limited utility in non-clinical studies of heavy drinking in randomly selected college students.
