小组成员流失威胁青少年物质使用研究的外部效度。对一个7年的青少年小组进行了检查，以确定磨耗效应是否因（1）评估的物质类型和（2）测量方法和统计分析类型而异。卡方和多变量方差分析（MANOVA）显示，研究辍学者更有可能使用物质，并报告了较高的平均使用物质在基线比留;磨损效应因物质而异;和平均使用比较更有可能检测磨损效应比使用-不使用比较。这些研究结果对青少年物质使用研究的影响进行了讨论。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
Panel attrition threatens external validity in adolescent substance use research. A 7-yr adolescent panel was examined to determine whether attrition effects varied by (1) type of substance assessed and (2) method of measurement and type of statistical analysis. Chi-squares and multivariate analyses of variance (MANOVAs) revealed that study dropouts were more likely to use substances and reported higher mean use of substances at baseline than stayers; attrition effects varied by substance; and mean use comparisons were more likely to detect attrition effects than use–nonuse comparisons. Implications of these findings for adolescent substance use research are discussed.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
