Health App Review Tool (HART): content validation through expert panel review.

The Health App Review Tool (HART) is an evaluation tool that is designed to help the users in evaluation of the health apps for Alzheimer's Disease and Related Dementias (ADRD) population. As the development of the HART continues, the domain items that HART addresses require evaluation to determine if they meet the intended required criteria for the users.To complete content validation of the HART 10 health care professions provided content validation of the HART via a content validation form. Specifically, data collection took place virtually through Microsoft Teams and Qualtrics-based content validity index. Following, revisions were made through a consensus process involving 3 rehabilitation experts, minimizing potential conflicts.Findings indicate 76 of 109 items were considered acceptable, 19 items were in need of review and 14 items in need of revision. In sum 30% of the total HART items required either review or revision to improve HART validity. The changes were implemented through consensus revisions.
