目的：采用间接告密者对大学生自我报告数据的效度进行独立评估。然而，目前还不清楚在什么情况下，附属报告在大学研究中可能是有效和有用的。我们提出了两项研究，使用在一所公立大学进行的简短干预预防试验中1264名大学生参与者的数据来检查这些问题的各个方面。方法：第一项研究描述了219对学生-辅助性信息者对酒精使用和问题报告的一致性的特征和预测因素。第二项研究调查了潜在的“管道效应”；也就是说，使用1264名学生的纵向数据，在一年的时间里，抵押品验证是否导致学生在随后两次调查评估中的自我报告发生变化。结果：非依赖型大学饮酒者低估了饮酒行为和后果，这一假设几乎没有得到支持。那些报告一起喝酒的次数更多、对报告更有信心、与参与者关系密切的侧支提供的报告与参与者的饮酒报告更一致。没有证据表明抵押品验证的管道效应提高了大学生在未来评估中自我报告的准确性。结论：这项研究的结果与已发表的大部分文献一致，表明使用附带报告来验证大学生(和成年人)的自我报告可能会导致错误分类错误的增加，而不是减少。这些发现表明，在大学环境中收集抵押品数据所需的时间和费用用处有限，最好是花在建立正确的评估条件上，以促进准确和诚实的自我报告。
Objective: Collateral informants have been used to assess independently the validity of college student self-report data. However, it is unclear under what conditions collateral reports might be valid and useful in college research. We present two studies that examine aspects of these issues using data from 1,264 college student participants in a brief intervention prevention trial conducted at a public university. Method: The first study describes the characteristics and predictors of agreement on reports of alcohol use and problems from 219 student-collateral informant pairs. The second study investigates potential "pipeline effects"; that is, whether collateral verification resulted in changes in student self-reports on two subsequent survey assessments over I year using longitudinal data from 1,264 students. Results: Little support was found for the assumption that nondependent college drinkers underreport drinking behaviors and consequences. Collaterals who reported more occasions of drinking together, higher confidence in the report and a close relationship with the participant provided reports that were more consistent with participant drinking reports. No evidence was found that pipeline effects of collateral verification improve the accuracy of college student self-reports at future assessments. Conclusions: The results from this study are consistent with much of the published literature showing that using collateral reports to verify the self-reports of college students (and adults) may result in increased, not decreased, misclassification error. These findings suggest that the time and expense required to collect collateral data in the college setting has limited utility and may be better spent on establishing the proper assessment conditions that will foster accurate and honest self-reporting.
