目的：进食评估工具是一个自我管理的，吞咽困难的特定结果工具。本研究旨在评估10项进食评估工具（EAT-10）的效度和信度。方法：调查包括4个阶段：1）行项目生成，2）行项目缩减和信度，3）标准数据生成，4）效度分析。所有数据均前瞻性收集。内部一致性采用Cronbach α进行评估。重测信度采用Pearson积差相关系数。通过将该仪器施用于健康志愿者的社区队列来获得规范性数据。有效性进行了评估，通过管理前和吞咽困难治疗后的仪器，并通过评估正常人和那些已知diagnosis.Results：共629调查482例患者之间的调查差异。最终仪器的内部一致性（Cronbach α）为0.960。重测项目内相关系数为0.72 ~ 0.91。正常队列的平均（+/- SD）EAT-10评分为0.40 +/- 1.01。食管吞咽困难患者的平均EAT-10评分为23.58 +/- 13.18，口咽吞咽困难患者为23.10 +/- 12.22，嗓音障碍患者为9.19 +/- 12.60，头颈癌患者为22.42 +/- 14.06，反流患者为11.71 +/- 9.61。有口咽、食管吞咽困难和头颈部肿瘤病史的患者EAT-10评分显著高于有反流或嗓音障碍的患者（p <0.001）。治疗后吞咽困难患者的平均EAT-10评分从19.87 ± 10.5改善到5.2 ± 7.4（p < 0.001）。规范性数据表明EAT-10评分为3或更高是异常的。该仪器可用于记录初始吞咽困难的严重程度，并监测患有各种吞咽障碍的人的治疗反应。
Objectives: The Eating Assessment Tool is a self-administered, symptom-specific outcome instrument for dysphagia. The purpose of this study was to assess the validity and reliability of the 10-item Eating Assessment Tool (EAT-10).Methods: The investigation consisted of 4 phases: 1) line-item generation, 2) line-item reduction and reliability, 3) normative data generation, and 4) validity analysis. All data were collected prospectively. Internal consistency was assessed with the Cronbach alpha. Test-retest reliability was evaluated with the Pearson product moment correlation coefficient. Normative data were obtained by administering the instrument to a community cohort of healthy volunteers. Validity was assessed by administering the instrument before and after dysphagia treatment and by evaluating survey differences between normal persons and those with known diagnoses.Results: A total of 629 surveys were administered to 482 patients. The internal consistency (Cronbach alpha) of the final instrument was 0.960. The test-retest intra-item correlation coefficients ranged from 0.72 to 0.91. The mean (+/- SD) EAT-10 score of the normal cohort was 0.40 +/- 1.01. The mean EAT-10 score was 23.58 +/- 13.18 for patients with esophageal dysphagia, 23.10 +/- 12.22 for those with oropharyngeal dysphagia, 9.19 +/- 12.60 for those with voice disorders, 22.42 +/- 14.06 for those with head and neck cancer, and 11.71 +/- 9.61 for those with reflux. The patients with oropharyngeal and esophageal dysphagia and a history of head and neck cancer had a significantly higher EAT-10 score than did those with reflux or voice disorders (p < 0.00 1). The mean EAT-10 score of the patients with dysphagia improved from 19.87 +/- 10.5 to 5.2 +/- 7.4 after treatment (p < 0.001).Conclusions: The EAT-10 has displayed excellent internal consistency, test-retest reproducibility, and criterion-based validity. The normative data suggest that an EAT-10 score of 3 or higher is abnormal. The instrument may be utilized to document the initial dysphagia severity and monitor the treatment response in persons with a wide array of swallowing disorders.
