摘　　要： 讨论了中介变量以及相关概念、中介效应的估计;比较了检验中介效应的主要方法;提出了一个检验程序,它包含了依次检验和Sobel检验.该程序检验的第一类和第二类错误率之和通常比单一检验方法小,既可以做部分中介检验,也可以做完全中介检验.作为示范例子,引入中介变量研究学生行为对同伴关系的影响. The concepts of mediator and related constructs, as well as the estimation of mediating effects were discussed. Based on the comparison of various testingmethods, a procedure was proposed which wasa composite test derived fromtwo existing testing methods.The newly proposed procedure is likely to be better than any single testing method in terms of the sum of type 1 and type 2 error rates. Moreover, it can be used to test both partial and full mediating effects. As an illustration, the procedurewas applied to an empirical study on students' antisocial (behaviors) and their effects on peer relations.
