目標：因應大型社區調查研究簡化問卷題目的需求，本研究目的為驗證及發展台灣簡易版OHIP量表，作為社區調查測量口腔健康相關生活品質(OHRQoL)評估工具。方法：以橫斷式調查(cross-sectional study)的1,402位台灣65歲以上老人口腔健康衝擊(OHIP)資料，使用「控制式廻歸程序」(controlled regression procedure)從49題OHIP版本挑選出7題題目為台灣簡易版 OHIP量表(OHIP-7T)；再選用此樣本資料與116位牙科贋復物患者資料，驗證OHIP-7T量表信效度檢定；最後選用91位完成贋復物治療追蹤患者的資料，分析量表使用在牙科臨床追蹤型研究(Longitudinal study)的感應度(responsiveness)。結果：以自覺口腔健康狀況及問題作為效標效度，65歲以上老人(F=93.44,p<.0001)及贋復物治療患者(F=5.86,p=0.0038)自覺口腔健 康狀況與OHIP-7T總分達顯著性差異；同樣地,65歲以上老人(t=-8.88,p<.0001)及贋復物治療患者(t=-2.02,p=0.0460)與OHIP-7T總分達顯著性差異。此外，OHIP-7T量表的內部一致性Cronbach's alpha值為0.79-0.83，其感應度(responsiveness)測量治療前後效果值(effect size, ES)為1.51。結論：本研究發展及驗證具良好信效度及感應度(responsiveness)的台灣簡易版OHIP量表(OHIP-7T)，提供未來國內大型研究調查使用。

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.
