Index of moderated mediation

Post by choiswf » Fri Dec 27, 2019 7:25 am

Hi everyone,

I'm running a moderated mediation model in SmartPLS 3 (Picture 1).

I'd like to report index of moderated mediation (w = P1*P2+P2*P5*M). I know that M refers to the latent variable scores of the moderator variable, and the latent variable scores can be found under results of PLS Algorithm (Picture 2). However, where can I get the value of M? To calculate the mean of these latent variable scores? or to multiply them?

Thank you for all your help!

The index of moderated mediation is given by p2*p5. You can find this as the specific indirect effect of Y1*M -> Y2 -> Y3. This is exactly p2*p5. You can assess its significance using bootstrapping.
