I would like to study the moderating effect of Knowledge Management process (4 factors namely: knowledge creation, storage, transfer and application) on ICT (2 factors namely supportive and collaborative tools) and firm performance (1 factor). How should I run the regression analysis in SPSS to know the moderating effect of KM process between ICT and firm performance?

I have more then one factors in constructs ICT and KM. Should I summate the scores of (ICT1+ ICT2) and KM process (KC+KS+KT+KA) to conduct the regression analysis?
