Why not write chain intermediary?

The effect is not significant. The mediation function is to study whether the independent variable X will first affect the dependent variable Y through the mediation variable M, and then affect the dependent variable Y. The final result of the chain mediation shows that the direct effect is not significant, the total indirect effect is not significant, and the effects of two separate mediations are not significant. In mediation research, there are many mediation variables between independent variables and dependent variables, which is called multiple mediation model.
