摘要註:	在研究社會科學、教育學和心理學等時，常探討變數間是如何互相影響，因而發展出中介變數(Mediator)和調節變數(Moderator)。調節式中介效果(Moderated Mediation Effect)是其中一種中介效果和調節效果的組合，指的是一中介變數影響解釋變數和相依變數之關係，而此中介效果會隨著調節變數的值而改變。檢定調節式中介效果的方法有很多種，許多研究者偏好使用以迴歸為基礎的檢定方法，其中常見的為係數的乘積(the Product of Coefficients)，假設此乘積服從常態性，以Sobel所提的一階標準誤較為被廣泛使用(First-Order Multivariate Delta Method)，但事實上此乘積並非為常態分佈，因此當樣本數不夠大時建議使用Bootstrap 方法。本文除了介紹中介效果模型和調節效果模型之外，我們延伸Preacher等人在2007年所列舉的五種調節式中介效果模型，探討在不同係數組合與五種檢定方法下，其檢定力之表現；更進一步提供研究者在研究調節式中介效果模型，決定樣本數大小時，為達到適當檢定力所需樣本數大小，給予一個可參考的依據。 When researchers study social science, education, psychology and so on, they often study how and why variables are related. Hence, mediator and moderator are developed. Moderated mediation effect is one of the combinations of mediation and moderation effects. It refers to a mediator affecting the relation between an independent variable and a dependent variable, and then the mediation effect depends on the value of the moderator. There are many test methods of moderated mediation effects. Many researchers prefer to use regression-based tests. The most common method is the product of coefficients and is assumed the product is normally distributed. First-order multivariate delta method (Sobel, 1982, 1986) was commonly used. In fact, moderated mediation effect is not normally distributed. We recommend using the bootstrapping method when sample size is not large enough.Except for introducing mediation and moderation models, we extended five moderated mediation models which were studied by Preacher et al. (2007). Using five testing methods to detect how many sample size required for different coefficients combination with appropriate statistical power. Moreover, we provide guidelines for researchers to study moderated mediation model in determining sample size.
