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.
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).
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.
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.
闭孔功能量表（OFS）是一种在任何语言中都没有正式效度测量的量表。本研究旨在将OFS从英文翻译并改编为中文，并检验其在癌症相关上颌骨切除术后使用闭孔假体的华语患者中的信效度。
三家三级口腔医院的133名患者完成了15项中文版OFS。其中，41名患者在首次测量一周后再次完成该量表。患者还完成了华盛顿大学生活质量量表中文版（UW-QOL，第4版）。
删除了第12项（“上唇感觉麻木”）以获得更好的统计拟合度。14项中文版OFS（OFS-Ch）显示出较高的内部一致性（Cronbach's alpha = 0.908）。大多数项目的重测信度系数超过0.90，表明具有较高的可重复性。验证性因素分析发现，该量表由三个相关因素组成：1）进食（4项），2）言语（5项），3）其他问题（5项）。探索性因素分析表明，这解释了总方差的70.2%。该量表具有显著的收敛效度和区分效度，能够有效区分Brown I型和IId型上颌骨缺损患者。
我们的结果表明，OFS-Ch量表是一种有效的工具，可用于评估闭孔假体患者的口腔功能障碍和外观满意度，并在临床环境中识别闭孔功能不良风险患者。
