  text: "Background: Functional abdominal pain (FAP) is a severely debilitating condition
    affecting approximately 11.7% of children and adolescents worldwide, often persisting
    into adulthood and significantly restricting daily life. Health literacy is essential
    for treatment success. To improve knowledge about the biopsychosocial factors
    influencing FAP and support its management, we developed an educational multimedia
    website (https://meine-bauchstelle.com).\r\nMethods: In a multicenter randomised
    controlled trial (RCT), patients with FAP (N = 166, age 5–17 years, M = 10.8,
    SD = 3.31; 53.6% female) and their parents were randomly assigned to an intervention
    group (IG: access to the website before the first measurement) or a control group
    (CG: no access to the website during data collection). The primary outcome was
    health literacy (knowledge and health behaviour) and secondary outcomes were abdominal
    pain symptoms and the physician-patient/parent interactions. Group differences
    were analysed using t-tests and multilevel models.\r\nResults: Patients in the
    IG who visited the website demonstrated significantly higher initial knowledge
    scores compared to the CG. Moreover, they reported significantly less pain-related
    disability across three assessments over 3 months. Parents who visited the website
    rated the physician-parent interaction significantly more positively than those
    in the CG.\r\nConclusions: The educational website efficiently increased patient
    knowledge about FAP and improved certain pain-related behaviours. It serves as
    an effective tool in conveying information about FAP in clinical practice. Future
    applications could extend to preventive measures in schools and other settings.\r\nSignificance
    Statement: The educational website about functional abdominal pain is effective
    in transferring knowledge, reducing pain-related disability, and improving physician-parent
    interactions. It can support physicians in day-to-day clinical practice by referring
    patients to the website for further information and might be extended as a preventive
    measure in schools."
