Contextual factors and continuance intention of mobile services

Mobile applications that allow users to perform activities on their mobile devices have attracted a substantial amount of attention in mobile commerce. The use of these application services (called mobile services) may be affected by contextual factors. In this paper, we investigate how contextual factors such as time pressure, location and other concurrent task may affect the intention to use a mobile service. A theoretical framework that combines Theory of Planned Behaviour (TPB) and Task-Technology Fit (TTF) and an empirical study was conducted. The results show that: 1) a higher degree of TTF resulted in a more positive attitude towards using a mobile service; 2) perceived behavioural control had a positive effect on user's intention to use communication, entertainment and data application services; 3) social norms affected the intention to use only in transaction-related applications; 4) contextual factors had moderating effects on the intention to use.
