Abstract: The mediation effect analysis is able to reveal the process and mechanism of the impact of independent variables on a dependent variable. As an important statistical method, the mediation effect analysis has become a hot topic in methodology research in the last twenty years. The development of domestic research on the methodology of mediation effect was systematically reviewed from the five aspects, including testing method, effect size, the mediation effect test of categorical variables and longitudinal data, and model expansion. Specifically, model expansions include multiple mediation models, multilevel mediation models, moderated mediation model and mediated moderation model. Finally, recent progresses of foreign methodological studies on mediation effect and the future research directions were discussed.
