This randomized controlled study aims to evaluate the efficacy of exposure-based Internet-delivered cognitive behavior therapy for children 8-12 years with Functional Abdominal Pain Disorders. The children participate along with their parents, who will also receive specific modules with information on how to support their children in the treatment. Predictors and mediators for treatment effects will be studied as well as the cost effectiveness of the intervention.
