Due to high personal, social, and economic consequences, proper management in its early stages is keyto reducing disability. The aim of this project is to co-develop a digital intervention for pediatric chronic pain (Digital SPA)with end-users and to evaluate its effectiveness and implementation outcomes in Spain.Methods: (Phase 1) Focus groups with patients, parents, and clinicians (n=5–6 each) will inform about unmet pain care needsand provide a starting point for co-designing the intervention. (Phase 2) Content creation and usability testing will be based onthe results of Phase 1, and the theory-driven development will follow the latest available evidence. The intervention will use validatedpsychological techniques focused on improving functioning by teaching pain coping skills. (Phase 3) Hybrid effectiveness–implementation trial. Participants (n=195) will be adolescents aged 12–17 years old with chronic pain and one of their parents.Assessments include physical function, pain, sleep, anxiety, mood, satisfaction and adherence to the treatment, and number ofvisits to the emergency room. A qualitative framework analysis will be conducted with data from Phase 1. Effects of the interventionwill be evaluated using linear multilevel modeling. The Consolidated Framework for Implementation Research (CFIR) andBehavioral Interventions Using Technology (BIT) frameworks will be used to evaluate implementation.Discussion: This study is expected to produce a co-created evidence-based digital intervention for pediatric chronic pain anda roadmap for successful implementation.Trial registration number YR 2023 FD 2023-12-19 LK https://hdl.handle.net/10630/30810 UL https://hdl.handle.net/10630/30810 LA eng NO 1. de la Vega R, Serrano-Ibáñez ER, Ruiz-Párraga GT, et al.
