ADHERE Trial: Strategies to Improve Mobile App Adherence

This study aims to evaluate the effectiveness of two communication interventions, compared to standard app notifications, in increasing adherence to a mobile health app among individuals with chronic low back pain. The main question it aims to answer is: Do phone calls or text messages increase adherence compared to app notifications in patients receiving a digital health intervention for chronic back pain? Participants will: A) Receive pain education and clinical hypnosis via a mobile app for managing chronic LBP; B) Will be contacted up to twice via phone call or text message, or they will only receive standard notifications from the app.
