OBJECTIVES: The aim of this study was to gather insights from a diverse group of stakeholders, identify existing challenges and explore associated solutions to develop a conceptual framework that assists in the development of a chronic low back pain (CLBP) self-management app. DESIGN: Codesign workshop methodology. SETTING: The study was conducted online, allowing for the participation of a diverse group of stakeholders. PARTICIPANTS: Participants were recruited through social media platforms and professional networks, including individuals with LBP for at least 3 months, healthcare professionals experienced in CLBP management and app developers with a background in digital health applications. INTERVENTIONS: The study used codesign workshops focused on brainstorming, communication and reflection exercises designed to foster collaboration and gather insights from stakeholders. OUTCOME MEASURES: Identification of key challenges and potential solutions for mobile health (mHealth) apps targeting CLBP. RESULTS: Nine stakeholders identified four primary challenges in current back pain apps: belief and trust, motivation, safety and usability. The group also collaboratively developed and proposed practical solutions to these challenges. CONCLUSIONS: This study illustrated the utility of the codesign workshop approach in generating critical insights for the development of a mHealth solution for CLBP. The insights gathered from these workshops can be used to inform future app development, potentially improving user engagement.
