Presentation Type: Poster Presentation
Background: Coronary artery disease (CAD) is a major health concern among adults. Mobile health (mHealth) applications have demonstrated potential in supporting self-care and promoting exercise adherence. However, deeper insights into user experiences, including barriers and facilitators, are needed to optimize app design and implementation.
Objectives: This study aimed to explore the experiences of adults at risk of CAD in using a mobile application designed to support exercise maintenance and health management.
Methods: Eighty-four adults at risk of CAD who were smartphone users were invited to use a self-developed mobile application comprising: (1) a CAD knowledge platform, (2) personalized exercise goals and tracking, and (3) a “Chest Pain – Things to Do” checklist. A qualitative descriptive study was conducted through in-depth individual interviews with a purposive sample of 15 participants. Semi-structured interviews, lasting 25–40 minutes, were conducted by a nurse and audio-recorded. Data saturation was reached after 15 interviews, which were transcribed verbatim and analyzed using content analysis.
Results: Three key themes emerged: (1) the app was perceived as acceptable and helpful for health maintenance; (2) facilitators included ease of use, engaging features, and habit formation; (3) barriers included privacy concerns and technical issues such as app downtime.
Conclusion: The findings provide valuable insights into user experiences with mHealth technology, informing future development to enhance self-care and support sustained exercise among individuals at risk of CAD.
