Comprehensive evidence has been provided for the significant increase in most chronic physical illnesses among children and adolescents. Therefore, early diagnosis and multimodal intervention in childhood and adolescence is required to prevent a chronic course of disease. Thus, patient education is essential for the medical child and adolescent rehabilitation.

Specifically, in addition to illness-specific modules, generic modules and treatment objectives should be incorporated.
