A comparison of competing theoretical models for understanding acceptance behavior of information systems in upscale hotels

This study investigated which intention-based model, namely: (1) the technology acceptance model (TAM; Model 1); (2) the theory of planned behavior (TPB; Model 2); and (3) the decomposed TPB (DTPB; Model 3) is best for predicting and explaining employees' behavioral intention to use hotel information system (HIS). Data were obtained from employees of 13 upscale hotels in Jeju, South Korea, and structural equation modeling (SEM) was employed to examine and compare the three competing theoretical models (CTMs) in terms of overall model fit, explanatory power, and paths significance. The findings of this study revealed that if the key objective is to predict behavioral intention to use HIS, the TAM is preferable. However, if the key objective is to explain behavioral intention to use HIS, the DTPB is preferable.
