BACKGROUND
The majority of research examining college drinking utilizes self-report data, and collateral reports have been used to verify participants' self-reported alcohol use.
METHODS
This meta-analytic integration examined the correspondence of over 970 collateral and participant dyads in the college setting.
RESULTS AND CONCLUSIONS
Results indicated that there is little bias (mean difference) between collateral estimates of participant drinking and participant's self-report. A cumulative meta-analysis revealed that this (null) effect was stable and unlikely to be altered by subsequent research or the existence of unpublished studies. Analysis of the agreement between collaterals and participant estimates (measured by intraclass correlation coefficients; ICCs) revealed moderate levels of agreement (mean ICC = 0.501). Examination of predictors of both bias and agreement in collateral and participant reports indicates a possible intentional and protective underreporting on the part of the collaterals. Ways to reduce this bias are discussed along with the value of using collaterals to verify participant self-report in the college setting.
背景
大多数研究大学生饮酒问题的研究都采用了自我报告数据，同时也使用了旁证报告来验证参与者的自我报告饮酒情况。
方法
本元分析综合评估了 970 多组大学生及其旁证报告者的数据。
结果与结论
结果表明，旁证报告者对参与者饮酒量的估计与参与者的自我报告之间几乎没有偏差（平均差异）。累积元分析表明，这种（无）效应是稳定的，不太可能因后续研究或未发表研究的存在而改变。对旁证报告者和参与者报告之间的一致性（通过组内相关系数[ICC]进行衡量）进行分析，结果显示出中等程度的一致性（平均 ICC = 0.501）。对旁证报告者和参与者报告中偏差和一致性的预测因素进行分析，表明旁证报告者可能有意且保护性地少报了参与者的饮酒情况。本文还讨论了减少这种偏差的方法，以及在大学生群体中使用旁证报告来验证参与者自我报告的价值。
