Pain in Pediatric Patients - Internet Interventions for Disorders of Gut-brain Interaction

Many children and adolescents often experience long-lasting stomach pain. In many cases, this is due to disorders of gut-brain interaction (DGBI), such as irritable bowel syndrome (IBS), functional abdominal pain, and functional dyspepsia. These conditions are caused by disrupted communication between the brain and the gut. They are linked to significant suffering, reduced quality of life, and higher school absenteeism. Psychological treatments such as cognitive behavioral therapy (CBT) have shown good effect, but waiting times within healthcare are often long. Therefore, there is a need for more accessible and cost-effective treatment alternatives. The goal of this clinical trial is to explore whether gut-directed hypnotherapy, already used successfully in the Netherlands, can be implemented as a new treatment option in Swedish healthcare. In addition, the study will compare gut-directed hypnotherapy with internet-based CBT (iCBT) to learn which digital treatment works best for children and adolescents with DGBI. Participants will: Be children or adolescents between 8 and 17 years old. First take part in a 4-week online education program called the "gut-school," which explains the stomach, the brain, and how symptoms can be managed. If symptoms remain after the gut-school, be randomly assigned to one of two digital treatments: iCBT (internet-based cognitive behavioral therapy). 10 week long. Gut-directed hypnotherapy, delivered as audio recordings to be used at home. 12 week long. Answer online survey questions before, during, and after treatment so researchers can follow their progress. These two treatments have never been directly compared. By comparing them, researchers hope to learn not only which treatment works best overall, but also which treatment is most suitable for different participants. The long-term aim is to make gut-directed hypnotherapy, already successful in the Netherlands, available as a treatment option in Sweden.
