Note: Red – Social influence and facilitating conditions are fundamental constructs in the UTAUT, serving as independent variables. Perceived trust, compatibility, and perceived cost are extended constructs that function as independent variables. Yellow –Perceived usefulness and perceived ease of use are fundamental constructs in the TAM, acting as mediating variables. Blue – Behavioral intention is a key construct in both the TAM and UTAUT, serving as the dependent variable.
