This study empirically analyzes an extended Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model that augments information quality to identify the determinants of continuous use intention for food delivery software applications. A sample survey of 340 respondents who had ordered or purchased food through delivery apps was used for the analysis. The results indicate that habit had the strongest influence on continuous use intention, followed by performance expectancy and social influence. Furthermore, information quality had an indirect effect on continuous use intention via performance expectancy. Consequently, this study confirms the importance of information quality, performance expectancy, habit, and social influence as factors in inducing users’ continuous use intention for food delivery apps. These findings expand previous research in online-to-offline business in the field of food services and suggest practical implications. Ultimately, the model proposed and validated in this study may be employed as a basis for future research on consumer behavior in the field of food e-commerce services.

This study aims to analyze the antecedent factors affecting continuous intention to use online to offline (O2O) accommodation app services and empirically verify them by applying an integrated model comprised of the value-based adoption model (VAM) and the expectation-confirmation model (ECM). For empirical analysis, a sample of 410 participants with experience reserving rooms using an accommodation app was used. The results showed that privacy risk had the biggest influence on perceived value, followed by technicality and usefulness. Moreover, confirmation and usefulness turned out to have a significant effect on satisfaction, and enjoyment had a negative effect on perceived value and satisfaction. As a result, the influence of perceived risk, technicality, usefulness, and confirmation on perceived value and satisfaction proved to be important in inducing continuous intention to use accommodation apps. These results are academically significant because they expand the scope of O2O business research in the fields of hotels and tourism. We outline several practical implications based on the study results.
