背景技术背景：本研究的目的是调查的维度，可靠性和有效性的替代版本的咀嚼功能问卷在部分齿状patients in Japanese.METHODS：受试者部分齿状患者参加修复诊所在东京医科齿科大学（N = 491，71%的女性，平均年龄（+/- SD）：63.0 +/- 11.5岁）。调查问卷要求每个受试者评价他或她咀嚼20种常见日本食物的能力。对于每一个人，将回答合并以产生咀嚼功能汇总评分，评分越高表示自我报告的咀嚼能力越好。采用探索性因素分析对量表得分的维度进行分析。为了进行有效性评估，我们计算了咀嚼功能评分和口腔健康相关生活质量之间的相关性（OHRQoL，由日本14项口腔健康影响量表（OHIP-14）测量）通过要求一组受试者（N = 62）完成两次问卷（间隔2周）来调查评分的内部一致性和重测信度。探索性因素分析提供了一些证据表明，自我报告的咀嚼能力可以用原始作者建议的汇总评分来表征。通过与OHIP-14评分的相关性（r =-0.46，95%置信区间（CI）：-0.53至-0.39），支持使用替代版本的问卷进行咀嚼功能评分的有效性;因此，咀嚼能力越好，OHRQoL受损程度越低。内部一致性"令人满意“，Cronbach α为0.90（95% CI下限：0.89）。的重测信度是“好”，与组内相关系数为0.69（95%CI：0.56至0.82）。结论：咀嚼功能问卷的替代版本可以作为一个独立的工具，因为证明的信度和效度的分数使用问卷部分齿状患者。
BACKGROUND: The aim of this study was to investigate the dimensionality, reliability, and validity of an alternate version of the chewing function questionnaire in partially dentate patients in Japan.METHODS: Subjects were partially dentate patients who attended the prosthodontic clinic at Tokyo Medical and Dental University (N = 491, 71% women, mean age (+/- SD): 63.0 +/- 11.5 years). The questionnaire asked each subject to rate his or her ability to chew 20 common Japanese foods. For each individual, responses were combined to yield a chewing function summary score, with higher scores indicating better self-reported chewing ability. We used exploratory factor analysis to investigate the scores' dimensionality. For validity assessment, we computed the correlations between the chewing function score and oral health-related quality of life (OHRQoL, as measured by the Japanese 14-item Oral Health Impact Profile (OHIP-14)) Internal consistency of scores and test-retest reliability were investigated by asking a subset of subjects (N = 62) to complete the questionnaire twice, 2 weeks apart.RESULTS: Exploratory factor analysis provided some evidence that self-reported chewing ability can be characterized by a summary score as the original authors suggest. Support for the validity of chewing function scores using the alternate version of the questionnaire was derived from correlations with OHIP-14 scores (r = -0.46, 95% confidence interval (CI): -0.53 to -0.39); thus, better chewing ability was associated with less impaired OHRQoL. Internal consistency was 'satisfactory,' with a Cronbach's alpha of 0.90 (lower limit of 95% CI: 0.89). The test-retest reliability was 'good,' with an intraclass correlation coefficient of 0.69 (95% CI: 0.56 to 0.82).CONCLUSION: The alternate version of the chewing function questionnaire can be used as a stand-alone instrument because of the demonstrated reliability and validity of scores obtained using the questionnaire in partially dentate patients.
