Abstract：
UNASSIGNED: The Obturator Functioning Scale (OFS) is a scale without formal measures of validity in any language. This study aimed to translate and adapt the OFS from English to Chinese and check its reliability and validity in Chinese-speaking patients with obturator prostheses after cancer-related maxillectomy.
UNASSIGNED: The 15-item Chinese preversion of the OFS was completed by 133 patients in three tertiary stomatological hospitals. Of these, 41 completed it again one week after the first measurement. The patients also completed the Chinese version of the University of Washington quality of life scale (UW-QOL, Version 4).
UNASSIGNED: Item 12 (\"upper lip feels numb\") was deleted to achieve a better statistical fit. The 14-item Chinese version of the OFS (OFS-Ch) demonstrated high internal consistency (Cronbach\'s alpha = 0.908). The test-retest reliability coefficients for most items exceeded 0.90, indicating substantial reproducibility. Confirmatory factor analysis found that the scale consisted of three correlated factors: 1) eating (four items), 2) speech (five items), and 3) other problems (five items). This explained 70.2 % of the total variance using exploratory factor analysis. The scale was significantly convergent and discriminant and could validly discriminate between patients with Brown I and IId maxillary defects.
UNASSIGNED: Our results showed that the OFS-Ch scale is a valid tool for evaluating oral dysfunction and satisfaction with appearance for patients with the obturator prosthesis and identifying those at risk of poor obturator function in clinical settings.

摘要：
■闭孔功能量表（OFS）是一种没有任何语言的正式有效性度量的量表。这项研究旨在将OFS从英语翻译和改编为中文，并检查其在癌症相关的上颌骨切除术后使用闭孔假体的中文患者中的信度和效度。
■由三个三级口腔医院的133名患者完成了OFS的15个项目的中文逆转。其中,41在第一次测量后一周再次完成。患者还完成了中文版的华盛顿大学生活质量量表(UW-QOL,版本4）。
■删除了项目12（\“上唇感觉麻木\”），以实现更好的统计拟合。OFS的14项中文版（OFS-Ch）表现出高度的内部一致性（Cronbach'salpha=0.908）。大多数项目的重测可靠性系数超过0.90，表明有很大的可重复性。验证性因素分析发现，量表由三个相关因素组成:1)进食(四个项目)，2)演讲(五项),3)其他问题(五项)。使用探索性因子分析，这解释了总方差的70.2%。该量表具有显着的收敛性和判别性，可以有效地区分BrownI和IId上颌缺损的患者。
■我们的结果表明，OFS-Ch量表是评估闭孔假体患者口腔功能障碍和外观满意度的有效工具，并确定在临床环境中存在闭孔功能不良风险的患者。
