Abstract

Background: To promote physical activity in post-treatment cancer survivors, a mobile application WExercise was developed using the Multi-Process Action Control Framework. It contains 10 weekly online lesson to facilitate reflective, regulatory, and reflexive processes to help participants to form and sustain physical activity behavior. Objectives: To test the usability and acceptability of WExercise in post-treatment cancer survivors. Methods: This study involved four phases: (1) preparing application content, (2) expert panel review (comprising oncology healthcare workers, exercise specialists, and behavior change researchers), (3) developing the app, and (4) usability test. The usability test was conducted cross-sectionally using direct observation of application navigation tasks, a quantitative survey, and qualitative interviews among 10 post-treatment cancer survivors. Results: In Phase 2, the expert panel rated the application highly on relevance, accuracy, comprehensiveness, meaningfulness, and easiness to understand (average score = 3.83 out of 4). The application was developed accordingly. In Phase 4, the System Usability Score was 75 %, greater than the cut-off point. Participants gave the items assessing acceptance of the application positive ratings (e.g., satisfaction = 4.30 out of 5). Based on the performance and feedback, the application was modified, including adjusting the font size and improving the visualization of buttons. Conclusion: Overall, experts and potential users considered the application relevant, usable, and acceptable. It has the full potential for further testing in a larger trial for its effectiveness in promoting physical activity in cancer survivors.
