Say I have an SEM model with 1 predictor variable (IV), 2 mediators (MV1, MV2) and 1 dependent variable (DV). Amos reports combined indirect effects for an IV on a DV. So the combined indirect effect would be the sum of the component indirect effects (i.e., the IV-MV1-DV indirect effect and the IV-MV2-DV) indirect effect.
Amos makes it easy to get bootstrap confidence intervals on combined indirect effects. However, hypotheses often concern component indirect effects (e.g., that MV1 mediates the effect of IV on DV).
How can I get confidence intervals on component indirect effects using Amos?
I'd be interested in both asymptotic and bootstrap confidence intervals. Could I just use the values and standard errors for the individual coefficients (i.e., MV1<-IV, and DV<-MV1)?
