Empowering WHISE women: usability testing of a mobile application to enhance blood pressure control.

Background: High blood pressure (hypertension) disproportionately affects African American/Black (Black) women. Previous research suggests that self-managing hypertension may be challenging, yet mobile applications (apps) can help to empower patients and increase medication adherence. We developed questions to test the usability of evaluating the WHISE (Wellness, Hypertension, Information Sharing, Self-Management, Education) mobile app for Black women with hypertension.
