I am not sure how to present the data on mediation analysis if actually all paths are not significant even path c and c'. Is it sufficient to report that there is no mediation effect after calculation path c (P>0.05)?
I used SPSS software to calculate simple mediation analysis. One DV one IV and one mediator. The mediation is verified by using Sobel test and Bootstrap method with 95% CI.
Sobel test is recognised as limitation in mediation analysis (possibiity of kurtosis).
Also, there is no point to dwell too much on your results as there is NO mediation effect found in your results. I reckon all paths are non-sig, hence path a, b, c and so on are non-significant. To be precise you could mention all your paths from your analysis.
