Task: Answer Verification
Input (English): Question: Is measurement of abdominal symptoms by validated questionnaire : a 3-month recall timeframe as recommended by Rome III superior to a 1-year recall timeframe?
Answer: The revised Talley-BDQ is reliable, with excellent reproducibility and validity. There were few differences in reported symptom rates between the 3-month and 1-year recall time versions of the questionnaire. A 1-year recall time may more efficiently capture infrequent or subtle symptoms.
Output (English): no
