Online banking information systems acceptance: a structural equation modelling analysis

Extending research on the technology acceptance model TAM, this paper develops an extended model of TAM, which besides TAM's original predictors of perceived usefulness PU and perceived ease of use PEOU, includes trust TR as an additional belief factor to predict the behavioural intention BI to use an online banking information system OBIS. The model was tested on a sample of 353 internet users in Pakistan. Using structural equation modelling with AMOS data analysis showed that all the proposed paths were significant and the model explained 44.7% of the variance in BI. As per expectation, highly significant paths were observed between the additional new factor of trust and the PU, followed by PU and BI. These findings suggest that inclusion of an additional factor within TAM extends its capability and validity to predict the individual's acceptance behaviour towards OBIS.
