BACKGROUND: No self-assessment instruments are available to assess symptoms of @entity1744 ( @entity5377 ). Our aim was to develop a disease-specific symptom questionnaire for use in @entity1 with @entity5377 . METHODS: Two-hundred-and-thirty-four @entity1 (77% F) with a mean age of 44 years took part in a psychometric evaluation using the previously validated Gastrointestinal Symptom Rating Scale modified for use in @entity1 with @entity5377 ( @entity5377 ). This version was tested against several disease-specific health-related quality of life (HRQL) questionnaires. Items with a high ceiling effect, items that measured a different construct, and items showing high correlation (>0.80) to another item were removed. A confirmatory factor analysis was also performed. RESULTS: The final questionnaire included 13 items depicting problems with satiety, @entity490 , @entity294 , @entity1142 and bloating. The internal consistency reliability was high, ranging from 0.74 ( @entity158 ) to 0.85 (satiety). The associations between similar constructs in the @entity5377 and the various HRQL scores confirmed the construct validity. @entity158 , bloating and @entity294 were the symptom clusters that impaired HRQL the most. CONCLUSION: The @entity5377 is a short and user-friendly instrument with excellent psychometric properties.

An XXXX -specific symptom questionnaire: development and validation.
