第三个变量效应阐明了其他两个变量之间的关系，并可以描述它们为什么相关或在什么条件下相关。本文演示了分析两个第三变量效应的方法：适度和中介。本文描述了学校心理学中检验调节和中介效应的效用，并对应用学校心理学研究中的分析方法进行了回顾和评价。适当的统计方法来测试的影响，并提供了不同的模型的效果大小的措施。扩展的基本主持人和调解人模型也进行了说明。
Third variable effects elucidate the relation between two other variables, and can describe why they are related or under what conditions they are related. This article demonstrates methods to analyze two third-variable effects: moderation and mediation. The utility of examining moderation and mediation effects in school psychology is described and current use of the analyses in applied school psychology research is reviewed and evaluated. Proper statistical methods to test the effects are presented, and different effect size measures for the models are provided. Extensions of the basic moderator and mediator models are also described.
