Research has shown that the prevalence of chronic pain in adolescents is high and increasing. These young people report significant changes in both their physical and psychological functioning. Currently, psychosocial treatments enjoy strong empirical support and are crucial to maintaining and improving the quality of life of adolescents suffering from chronic pain. However, the availability of these evidence-based interventions is insufficient to meet the high demand, especially outside of large cities. The aim of this project is to develop a digital treatment that helps improve the quality of life of adolescents with chronic pain and complementary websites for their parents and teachers.
