Therefore, in this
current study, these two most popular models have been selected as the theoretical
foundation of the social behavioral model, and few additional constructs have been
adapted from other models. The social behavioral model adapted three constructs from
the TAM: perceived ease of use, perceived usefulness, and attitude toward engagement;
the two constructs adapted from the TPB are perceived behavioral control and subjective
norm. Three new constructs—perceived risk, perceived enjoyment, and image—have
been incorporated as TAM2 constructs.
