Smartphone App for Adolescents With Idiopathic Scoliosis

Официальное название

Evaluating the Impact of a Smartphone App on Health Outcomes and Treatment Adherence in Adolescents With Idiopathic Scoliosis: A Mixed Method Quasi-Experimental Study

Обзор

This study aims to evaluate a smartphone application (DinSkoliose) designed to support adolescents with idiopathic scoliosis (AIS) in managing their condition and following their treatment. Adolescents with AIS often find it challenging to adhere to conservative treatment, such as wearing a brace or performing physiotherapy exercises. The app was developed specifically for this study as a theory-informed digital health intervention to support self-management and treatment adherence. It includes features such as symptom tracking, educational content, reminders, and social support. Participants will use the app for 12 weeks in their everyday environment alongside their usual care. They will complete questionnaires before and after the intervention and participate in an interview to share their experiences. The study will examine whether the app can improve health-related behaviors, including treatment adherence and self-management, and whether it is feasible and acceptable for adolescents with scoliosis.The app is meant to complemen the current AIS treatment, doesn't substitute it.

Подробное описание

This study is a quasi-experimental, one-group pretest-posttest study designed to evaluate the feasibility, acceptability, and preliminary effectiveness of a smartphone application (DinSkoliose) for adolescents with idiopathic scoliosis (AIS).

AIS is a common spinal condition that often requires long-term conservative treatment, including brace use and physiotherapy scoliosis-specific exercises. Treatment success is highly dependent on adherence; however, adherence is often limited by physical discomfort, psychological factors, and lack of continuous support.

The DinSkoliose app is a personalized, theory-informed digital health intervention developed specifically for this study using a user-centered co-design approach. The app is grounded in behavioral theories of motivation and self-management and includes features to support treatment adherence, such as tracking of brace use and exercises, monitoring of symptoms (e.g., pain and mood), educational information, reminders, and structured social support.

Participants will use the app over a 12-week period in their natural environment alongside their usual care, with no additional clinical intervention. Outcomes will be assessed at baseline and post-intervention using validated questionnaires measuring health behaviors, self-management, self-efficacy, social support, and patient activation. App usability, engagement, and acceptability will also be evaluated.

In addition, semi-structured interviews will be conducted after the intervention to explore participants' experiences and identify strengths and areas for improvement. The results will inform further development of the app and future evaluation in larger controlled studies.
