An extended UTAUT model to explain the adoption of mobile banking

Abstract

This research attempts to identify the factors leading to the adoption of mobile banking and the degree of influence of each one of the factors in Thailand. It proposes a comprehensive framework that extends the existing UTAUT model with important constructs such as perceived credibility, perceived cost, and perceived convenience. A three-pronged approach, consisting of an extensive review of the literature, expert interviews, and a field survey of mobile banking adoption is put forward. A field survey of respondents was undertaken with both convergent and discriminant validities being conducted. The results of the structural equation modeling show that performance expectancy, effort expectancy, social influence, perceived credibility, perceived convenience, and behavioral intention to use mobile banking posited a positive relationship. Contrary to previous studies, the hypotheses testing perceived that financial cost and facilitation conditions in the adoption of mobile banking were not supported. Discussions and conclusions including academic and practical implications are also presented.
