简要总结

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.

详细描述

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
