The X with M interaction should be estimated and tested and added to the model if present. @article{Baron1986TheMV, title={The moderator-mediator variable distinction in social psychological research: conceptual, strategic, and statistical considerations.

The results of the mediating effect are further confirmed by Sobel’s (1982) test, the Aroian’s (1944) test, and the Goodman’s (1960) test. Mediation in health research: A statistics workshop using SPSS Dr. Sean P. Mackinnon Dalhousie University Crossroads Interdisciplinary Health Conference, 2015 ...

27% auf einen direkten Effekt von X auf Y (byx = 0,2). An investigator may first ask whether the analysis meets the Baron and Kenny criteria for establishing mediation and, if so, the analyst then conducts the Sobel test to attest to the validity of the conclusions reached without it.

They published a paper in 1986 and it described how we should test for mediation. (Baron & Kenny, 1986) defined three conditions necessary for mediation, and the updated version by (Kenny, 1998) describes four steps to infer mediation. Baron, R. M., & Kenny, D. A. In this method for mediation, there are two paths to the dependent variable. The outcome of a If, however, only the first three steps of Baron & Kenny’s procedures are satisfied, then partial mediation is observed in the data.

Further, the relative simplicity of this approach has lead to its establishment as the staple method of teaching mediation within the classroom. using the Baron and Kenny’s (1986) three-step mediation analysis and chi-square (χ2) difference test.
