[Development and verification of the Izumo Scale, new questionnaire for quality of life assessment of patients with gastrointestinal symptoms].
The Izumo Scale is a new questionnaire for the assessment of quality of life of the patients with gastrointestinal symptoms comprehensively. The validity and reliability of the scale were verified in 170 patients with gastrointestinal symptoms. Spearman's rank correlation coefficient between the Izumo Scale and visual analog scale (VAS) showed a positive correlation of 0.581-0.753. Internal consistency was also good with Cronbach's coefficient alpha of 0.616-0.805. The reproducibility was good with an intra-class correlation coefficient of 0.755-0.887. The results suggest that the Izumo Scale may be useful as a disease-specific quality of life assessment scale for patients with gastrointestinal symptoms.
