Clinical Trial[Development of Japanese version of QOL questionnaire for bladder and prostate cancer patients using FACT-Bl and P: pilot study].
Quality of life (QOL) has been known to be a prognostic factor as well as the endpoint of treatment efficacy in many clinical fields. We have begun a US-Japan collaborative project introducing a QOL questionnaire, the FACT (Functional Assessment of Cancer Therapy), into Japan. We report on the translation process, results of the pilot study, and future plans for translating the Japanese version of the FACT subscales, FACT-Bl (for bladder cancer) and FACT-P (for prostate cancer). ⋯ There was satisfactorily high internal consistency of FACT-G of both bladder and prostate cancer patients. FACT-Bl study included patients having undergone radical cystectomy as well as those who had not. Because not all items were answered by all patients, the Cronbach's alpha coefficient for the FACT-Bl subscale could not be computed. Further evaluation of the FACT-Bl concerning the surgical procedures affecting QOL is needed. We are currently planning to make the further refinement of the questionnaire in order to make it more suitable for bladder cancer patients. FACT-P subscale had an alpha coefficient of 0.82 and was determined to be useful in its present form.
