User acceptance of self-service technologies: An integration of the technology acceptance model and the theory of planned behavior

This study examines what may affect consumers' intention to use a self-service technology (SST). The objective of this study is to advance our understanding on the intention to use SSTs by comparing and integrating the theory of planned behaviour (TPB) and the technology acceptance model (TAM) as they relate to this issue. Data was collected from 280 adult consumers, and a structural equation modelling approach was employed to test the hypotheses. Although attitude, subjective norm, perceived usefulness have direct positive relationships to behavioural intention to use a SST, perceived behavioural control plays the most important role in explaining the intention to use SSTs. We conclude with managerial implications and directions for future research.
