Objectives: The aim was to develop and validate the Taiwanese short-form of the Oral Health Impact Profile-an instrument used to assess oral health-related quality of life. Methods: A sevenitem short form was developed using the best subset controlled regression procedure. Two samples, one from the general elderly population (n=1,402) and the other from among patients with prostheses (n=116) were used to investigate validity and internal consistency. Responsiveness was assessed in 91 of the patients treated with prostheses. Results: Associations between (OHIP-7T) scores and self-reports of oral health status and disorders in the general elderly population and among prosthetic patients were interpreted as support for validity. The instrument's internal consistency (Cronbach's alpha: 0.79–0.83) and responsiveness (effect size: 1.51) were sufficient. Conclusions: This study developed and validated the sufficient discriminatory ability and responsiveness of the shortform OHIP-7T, and it may now be used in national surveys in Taiwan.
