ABSTRACT

Background:

Maintaining user engagement with mobile health (mHealth) applications (apps) can be a challenge. Previously, we developed a conceptual model to optimize patient engagement in mHealth apps by increasing health literacy, enhancing technical competence, and improving feelings about participation in clinical trials.

Objective:

This paper provides proof-of-concept for iteratively testing this engagement approach.

Methods:

We collected data from six participants using an app that showed a series of educational videos and obtained additional data via questionnaires. The videos were designed to increase health literacy, enhance technical competence, and improve feelings about participation in clinical trials. The study measured changes in participants knowledge and feelings using semi-structured interviews. We collected feedback on the videos and content and then revised specific videos and content based on this feedback and conducted participant reassessments.

Results:

Findings support the feasibility and importance of an iterative approach to creating and refining engagement enhancements in mHealth apps. Of the three educational videos, participants rated the video to improve technical competence the highest.

Conclusions:

Tailoring app engagement material to individual needs could be the most useful approach and can be incorporated for use in health intervention and clinical trial apps. Attention should be given to avoiding inadvertent adverse affective variables. While mHealth apps have shown promise, participants are more likely to drop out than to be retained. This study highlights the potential for mHealth researchers to test and refine mHealth apps using approaches to better engage users. Clinical Trial: Not applicable
