Limitations and future lines of research
This article presents a series of limitations that should be debated and that generate new lines of research for the future. Firstly, limitations were found in the selected sample; participating users in the sample limited the interaction with the tool to the viewing of a video, through which they then answered questions in a survey. In this sense, our research has focused on the measurement of an intention, not on measuring actual behavior. Consequently, our work could be extended in the future with real experience with use of the real tool, making pertinent comparisons between intention and behavior, assessing the possible prior expectations of users and the effects on them once the user has actually interacted with the mobile application. Furthermore, methodological limitations were also found when conducting research, since the total sample was fairly small. In this regard, we have to remain cautious when generalizing the results of this research since it uses a small-sized sample In order to overcome this limitation, the sample should be extended and/or approaching other modeling tools based on covariance which are more appropriate for samples of this size, such as the partial least square (PLS) modeling technique. Therefore, in future studies, it would be advisable to try to improve the representativeness and thus, the greatest potential for generalization of results from a larger sample nationwide.
