Brief summary
Development, validation and evaluation of a new multimodal questionnaire to assess and quantify the abdominal involvement in patients with the inherited life shortening multi-organ disease Cystic fibrosis. In the stepwhise development of the patient reported outcome measures (PROM) repeadedly, CF-patients, their families as well as professionals working in different fields of CF-care will be included.
Detailed description
Development of a multimodal questionnaire considering the FDA guidelines for development of a PROM, the CFAbd-Score * Evaluation of reliability of the questionnaire by examining internal consistency and construct validity * Evaluation of reproducibility of the questionnaire by re-testing of patients * Assessment of cross-generational applicability of the questionnaire by sub-scoring of age groups * Evaluation of the responsiveness of the score by comparison with age-matched healthy controls * Assessment of putative relationships of abdominal symptoms with faecal inflammatory markers * Assessment of applicability of the questionnaire in other CF centers * Transfer the CFAbd-Score to other countries and languages Development and validation of a CF-specific tool for daily assessment of abdominal symptoms (patient diary), the CFAbd-day2day Development and validation of a CF-specific tool for assessment of abdominal symptoms in children \< 12 years of age, the CFAbd-kid
