中介模型应用广泛，中介效应的检验也很多。研究人员在规划中介研究时最常见的问题之一是，“在测试中介时，我需要多少受试者才能获得足够的功效？”本文介绍了六种最常见和最推荐的各种参数组合中介测试所需的样本量，为研究人员设计研究或申请资助时提供指导。
Mediation models are widely used, and there are many tests of the mediated effect. One of the most common questions that researchers have when planning mediation studies is, "How many subjects do I need to achieve adequate power when testing for mediation?" This article presents the necessary sample sizes for six of the most common and the most recommended tests of mediation for various combinations of parameters, to provide a guide for researchers when designing studies or applying for grants.
