The analysis of moderating or mediating effects is widely used in questionnaire based research.Several ways were summarized to find modeling evidence for mediating and moderating effects analysis.From both practical and theoretical perspectives,we explain why there are so many empirical articles on moderating or mediating effects.Basically,it cannot be generalized that having too many articles of this kind is not ap-propriate,the correct approach is to examine whether the model assumptions in an article are reasonable and whether the statistical methods are used appro-priately.
