Validating the TAM Constructs with Behavioural Usage of Facebook

This article investigates if the TAM (Technology Acceptance Model), which has been a widely used model for predicting user acceptance of innovations, is still effective for the innovation that has long been experienced b y the users. The hypothesised relationships were based on certain psychological constructs of TAM for predicting behavioural intention toward using a system. Facebook was selected as the technological instrument for testing TAM. SEM (Structural Equation Modeling), a comprehensive statistical approach, was selected for testing the hypothesised relationships. The results show that the relationships of TAM constructs are still valid when experimented on an innovation that has long been experienced by the users.
