In the TAM, the user’s attitude toward using technology can be mediated by one’s perceived ease of use and perceived usefulness, which, in turn, can be afected by external variables consisting of quality factors and a personal factor. In this study, we set system quality and information quality as the quality factors and self- efcacy on a computer as a personal factor. We constructed a model of the acceptance of a MBL based on the TAM, which included latent variables, such as system quality, information quality, self-efcacy on a computer, perceived ease of use, perceived usefulness, and behavioral intention to use the MBL; then, we measured such variables by using questionnaires. We analyzed the model by using partial least-squares structural equation modeling with the R package. As a result, we found that both system quality and self-efcacy on a computer afected the perceived ease of use while only system quality afected the perceived usefulness, which, in turn, afected the behavioral intention to use the MBL.
