Validation of a Japanese Version of the Decision Regret Scale

Abstract

Background and Purpose: In Japanese health care, no current index measures patient satisfaction with decision making during the treatment process. Our research aimed to test a Japanese version of the Decision Regret Scale (DRS) for this purpose. Methods: We distributed a Japanese version of the DRS twice, 3 weeks apart, to 80 postoperative patients younger than the age of 85 years with inguinal hernias, cholelithiasis, cholecystitis, and gallbladder polyps. Results: The reliability (α = .85) and validity of the Japanese version of the DRS was demonstrated among postoperative patients. Conclusion: The Japanese version of the DRS will have significant implications for clinicians in improving their shared decision making with patients.
