Conclusions
Overall satisfaction, usability, and usefulness of the HEAR-aware app were reasonable to good, indicating sufficient acceptability. The large variance between participants in these outcomes, and the suboptimal compliance to the app’s EMA/EMI elements indicated room for improvement for part of the participants. The 10 new TB-specific SoC scales generally showed fair-to-excellent test–retest reliabilities, and sufficient construct validity, indicating their promise for use in future studies. The results of this study may inform future research on how to tailor educational app materials to a person’s SoC.
