So my correlational results show that X is positively related to M (.70), and X and M are both negatively related to Y (-.52 and -.28).
All three correlations are as expected, and when I run the 'X -> M -> Y' mediation model, the indirect effect comes out to be significant. However, I see that the regression coefficients for the path b (association between M and Y controlling for X) are positive (.15).
I read that this is called inconsistent mediation, and my main question is if I can still consider this indirect effect as significant (and ok to report).
Also, I wonder if this is related to a ceiling effect (because the variable M IS highly negatively skewed towards the max).. or the association between M and Y being just too weak compared to X and Y...
