I ran Hayes process macro in spss. In my results below, you'll see that indirect effects are significant on both levels of my Independent Varaible (IVAlgo), however the index of moderated mediation is not significant. Can I interpret this as the two mediators (Difficul and Trust5) mediates X on Y on all levels of W? It is my understanding that the index of moderated mediation just tests whether the mediation depends on levels of W. However, even though the index is not significant here, my results still provide evidence that there is mediation.
