Abstract
Theory of Reasoned Action (TRA), postulated by social psychologist, has been established to be relevant in guiding Information Systems studies. The theory resulted from attitude research using the Expectancy Value Models. Therefore, TRA can be more effective if extended with additional determinants/constructs of systems use. The purpose of this study was to validate the additional constructs expected to strengthen TRA. Both qualitative and quantitative research methods were used in compilation of this paper. Additional determinants have therefore been validated using correlation and are illustrated in this article to demonstrate their effects on technology use in an Information Systems discourse. To achieve this, the authors used the findings from a study that was conducted in setting that presented rural urban characteristics, varied social economic characteristic as well as the varied age sets. The paper puts clearly the possibility of applying the theory of reasoned action in an information systems discourse, with additional constructs, giving birth to the Extended Theory of Reasoned Action.

Ajzen and Fishbein formulated the Theory of Reasoned Action (TRA), by 1980
Field interview data revealed some of the factors that mobile phone users perceived to influenced mobile phone money use in the study area
Even though most of the users acknowledged that mobile phone money was in did useful even in the rural communities, especially when an individual do not have cash, and that it provided flexibility, they still had a strong opinion that it was a technology meant for those who were either educate or wealthy
Summary
Ajzen and Fishbein formulated the Theory of Reasoned Action (TRA), by 1980 This resulted from attitude research using the Expectancy Value Models [1] [2]. Among other things, to explain how and why attitude affects behavior, was very important. This is very important in mirroring Information Systems studies. Social psychologists suggest that attitude includes behavior and cognition, and that both attitude and behavior, are positively correlated. This is the reason why Information Systems study should adopt Theory of Reasoned Action in guiding technology use studies. The paper identified other constructs that influences technology acceptance and use, and in this context factors affecting mobile phone money use, and further validating them using correlation analysis
