This study aimed to culturally adapt and validate the Chinese Mandarin version of the 10-Item Eating Assessment Tool (EAT-10-CM) for Chinese community-dwelling older adults.
A total of 346 Chinese community-dwelling older adults participated in this study, with 47 individuals included in the second testing phase. Reliability was assessed through internal consistency and test-retest reliability. Validity analysis covered several aspects: instrument validity, convergent validity, concurrent validity, content validity, and discriminant validity. Instrument validity was assessed by comparing EAT-10-CM scores between participants with and without oropharyngeal dysphagia (OD). Convergent validity was evaluated by comparing the EAT-10-CM with the Dysphagia Handicap Index (DHI). Concurrent validity was assessed by comparing the EAT-10-CM with the Penetration-Aspiration Scale. Content validity was examined using the content validity index, based on the input of 10 expert reviewers. Discriminant validity was analyzed using receiver operating characteristic (ROC) analysis to determine the optimal cutoff value.
The Cronbach's alpha for the total scale and individual items was > 0.9, indicating excellent internal consistency. Test-retest reliability was assessed using Pearson's correlation analysis, which showed a strong correlation ( > .7), demonstrating good stability over time. Significant differences in EAT-10-CM scores were observed between participants with OD and healthy individuals, supporting the instrument's ability to differentiate between these groups. The EAT-10-CM showed significant correlations with the DHI and the Penetration-Aspiration Scale ( < .001). The content validity index was 0.95 for the scale and ≥ 0.8 for each item. ROC analysis determined an optimal cutoff value of 3.00, with corresponding sensitivity and specificity values of 0.865 and 0.940, respectively.
The EAT-10-CM is a culturally adapted and validated instrument specifically for Chinese older adults with good reliability and validity. The optimal cutoff value of 3.00 provides a useful threshold for clinical assessment.
本研究旨在对中文版10项饮食评估工具（EAT - 10 - CM）进行文化调适，并验证其在中国社区居住老年人中的有效性。
共有346名中国社区居住老年人参与了本研究，其中47人纳入第二测试阶段。通过内部一致性和重测信度评估信度。效度分析涵盖多个方面：工具效度、收敛效度、同时效度、内容效度和区分效度。通过比较有和没有口咽吞咽困难（OD）的参与者之间的EAT - 10 - CM得分来评估工具效度。通过将EAT - 10 - CM与吞咽障碍 handicap指数（DHI）进行比较来评估收敛效度。通过将EAT - 10 - CM与渗透 - 误吸量表进行比较来评估同时效度。基于10位专家评审的意见，使用内容效度指数检查内容效度。使用受试者工作特征（ROC）分析来确定最佳截断值，以分析区分效度。
总量表和各项目的Cronbach's alpha均>0.9，表明内部一致性极佳。使用Pearson相关分析评估重测信度，结果显示相关性很强（>.7），表明随时间具有良好的稳定性。在有OD的参与者和健康个体之间观察到EAT - 10 - CM得分存在显著差异，支持该工具区分这些群体的能力。EAT - 10 - CM与DHI和渗透 - 误吸量表均显示出显著相关性（<.001）。量表的内容效度指数为0.95，各项目≥0.8。ROC分析确定最佳截断值为3.00，相应的灵敏度和特异度值分别为0.865和0.940。
EAT - 10 - CM是一种经过文化调适并验证有效的工具，专门针对中国老年人，具有良好的信度和效度。最佳截断值3.00为临床评估提供了有用的阈值。
