The influence of personality traits on mobile payment adoption: The moderating role of extraversion and neuroticism

The integration of advanced technologies into mobile devices is transforming mobile payments and facilitating transactions anytime and anywhere. We examine how performance and effort expectancy, perceived risk, and social influence shape mobile-payment intention, and how extraversion and neuroticism moderate these relationships. By combining the Unified Theory of Acceptance and Use of Technology (UTAUT) with theories on perceived risk and personality traits, this research provides deeper insights into consumer behavior regarding mobile payment adoption. Data were collected from 526 valid responses through a commercial data collection firm in the United States, targeting active mobile payment users. Structural equation modeling (SEM) was employed to analyze the proposed model. The findings highlight that perceived risk significantly impedes adoption. While extraversion did not significantly moderate the relationships among performance expectancy, perceived risk, social influence, and the intention to use mobile payments, neuroticism had a substantial moderating effect on these relationships. This underscores the complex roles of personality traits in technology adoption and points to the need for further research into these nuanced effects. The study enhances the literature on consumer behavior in mobile payments and suggests avenues for future research.
