Hi

in jAMM you get the "Moderation effects (interactions)" table that show you the K-1 contrasts needed to test the overall interaction. Thus, If you inspect that table, you'll see K-1 interactions that inform about which difference is significant and which is not.

Assume you have X , M and Y and a moderarator Q with three groups. In the table you'll see

X:Q12->M (this tells you if the effect of X on M is difference between Group 1 and 2 of Q)

X:Q13->M (this tells you if the effect of X on M is difference between Group 1 and 3 of Q)

M:Q12->Y (this tells you if the effect of M on Y is difference between Group 1 and 2 of Q)

M:Q13->Y (this tells you if the effect of M on Y is difference between Group 1 and 3 of Q)

Knowing this, you can interpret which groups differs in the mediated effects.

There is no multiple comparisons, we do not feel it's a good idea to run post-hoc tests on mediated effects, mainly because there's almost no literature supporting this analysis. However, we may implement it in the future.
