PURPOSE: The aim of the study was to conduct a psychometric evaluation of the fecal incontinence quality of life scale (FIQL) in the Japanese language using rigorous methodologies. METHODS: The FIQL was translated into Japanese. After being linguistically validated, the Japanese version of the FIQL was administered to a sample of 119 patients who completed the questionnaire at baseline and again after 2 weeks. The patients filled out a general questionnaire regarding health (the Short-Forum 36 Health Survey), and the severity of incontinence was assessed at baseline (Wexner scale). RESULTS: Internal consistency was good/excellent for all scales (Cronbach's alpha >0.70, between 0.72 and 0.94). Stability over time was good for all scales (Intra-class correlation >0.80, between 0.86 and 0.93). The four scales of the FIQL were significantly correlated with the scales of the generic questionnaire on health (P < 0.0001) and the Wexner scale (P < 0.0001). The mean FIQL score improved significantly after treatment in the 22 patients whose Wexner scale scores decreased >4 points, thus indicating good sensitivity in all four scales and the total scale. CONCLUSIONS: The linguistic and psychometric evaluation demonstrated the validity of the Japanese version of the FIQL.
