Hypothesis
The study aims to test the reliability and validity of a Japanese version of the IBS-QOL.
Conclusion
The IBS-QOL-J is a reliable instrument to assess the disease-specific quality of life for IBS in Japanese patients.
Supporting Evidence
- The IBS-QOL-J demonstrated high internal consistency with a Cronbach's alpha of 0.96.
- The overall score of IBS-QOL-J was significantly correlated with overall severity of IBS symptoms.
- Patients with continuous abdominal pain had significantly lower scores on the IBS-QOL-J.
Takeaway
This study created a Japanese version of a questionnaire to help understand how irritable bowel syndrome affects people's lives, and it works well.
Methodology
The IBS-QOL was translated into Japanese and tested for reliability and validity with 49 patients at Tohoku University Hospital.
Limitations
The study was cross-sectional and had a relatively small sample size from a single hospital.
