• Background: Chronic abdominal pain (CAP) in childhood is a commonly occurring condition and shows a high stability. Psychosocial dysfunctioning of children, such as increased stress experience, is a burden for children and parents and complicates clinical management. Additional comorbid disorders may develop. To minimize the onset of such disorders, treatment at an early stage and taking psychosocial aspects into consideration is strongly recommended. Through this approach, the cognitive-behavioral, child-centered group program 'Stop the pain with Happy-Pingu' was developed, applied, and subsequently evaluated. What is the psychosocial situation of the affected children? Can the cognitive-behavioral group program be applied to improve psychosocial limitations? Method: The cognitive-behavioral group program comprises 6 weekly sessions for children and 1 single meeting for parents. In a randomized controlled study, the program was evaluated with 29 children aged between 6 and 12 years.

Method: The cognitive-behavioral group program comprises 6 weekly sessions for children and 1 single meeting for parents. In a randomized controlled study, the program was evaluated with 29 children aged between 6 and 12 years. The evaluation was based on a comparison between the intervention group (IG) and the waiting list control group (WLC), measured at 3 measurement points: T1 (pre), T2 (post), and T3 (3-month follow-up). Results: Emotional problems in particular can emerge in children with CAP. The program was well received, with a high level of participation through to completion. The results demonstrate that children participating in the IG experience significant stress reduction and improved psychosocial functioning compared to children participating in the WLC. The effect sizes range from medium to high. Conclusions: Drawing upon the above findings, multimodal cognitive-behavioral techniques appear to be suitable to successfully treat children with CAP. However, further controlled studies are required to identify the specific elements of the training that are most effective in reducing pain.…
