The Influence of Performance Expectancy and Effort Expectancy on the Use of a Purchasing Application in Brazil

Cássio Miroma Reis Gomes, Josivania Silva Farias

Abstract


Based on the Unified Theory of Acceptance and Use of Technology (UTAUT), this work investigated the influence of performance expectancy (PE), effort expectancy (EE), and socio-demographic user profile on the use of a mobile software application for retail purchases in the Brazilian context. We are living in a "mobile" world, so it might be expected that user experience with such technologies would be positive. With 171 valid questionnaires, linear regression, factor analysis, means and standard deviations, and nonparametric statistical techniques were used in the data analysis. Findings revealed that frequent users of the software application have considerable levels of performance expectancy (PE) and effort expectancy (EE). Gender was found to influence attitudes with respect to EE but not those with respect to PE. Experience reported with the application had no significant correlation with cell phone use for either PE or EE, although it was significantly correlated with the frequency of use of mobile technologies in general. Inferential tests with linear regression showed that age and PE had a positive influence on the use of the application but that EE had a negative influences on use. This study supports the importance of UTAUT for research on technology adoption in geographical contexts different from those usually studied by the proponents of this theory.
