Refinement of Health App Review Tool (HART) through stakeholder interviews: HART 2.0.

ABSTRACT

The Health App Review Tool (HART) is a novel assessment designed to match users with Alzheimer's disease or related dementias (ADRD) and caregivers to mobile applications that support health and wellness. The objectives of this study were to gather stakeholder feedback on the HART and then to implement revisions. Thirteen participants completed in-depth Think Aloud interviews. Participants shared qualitative feedback on each HART item. Participant feedback was analyzed via in-depth video-audio review. Feedback was implemented as actionable HART revisions. On average, the majority of participants rated items as "adequate"; however, qualitative findings indicated the need for improvement in conciseness, clarity, and understandability. Conciseness was addressed by combining related concepts into multi-items, clarity through the addition of specific examples, and understandability through improved verbiage. The HART has been refined from 106 items to 17 items through extensive revisions to the clarity, conciseness, and explanations provided throughout the assessment.
