The Ohkuma questionnaire is a validated screening tool originally used to detect dysphagia among patients hospitalized in Japanese nursing facilities. The purpose of this study is to evaluate the reliability and validity of the adapted Greek version of the Ohkuma questionnaire. Following the steps for cross-cultural adaptation, we delivered the validated Ohkuma questionnaire to 70 patients (53 men, 17 women) who were either suffering from dysphagia or not. All of them completed the questionnaire a second time within a month. For all of them, we performed a bedside and VFSS study of dysphagia and asked participants to undergo a second VFSS screening, with the exception of nine individuals. Statistical analysis included measurement of internal consistency with Cronbach's α coefficient, reliability with Cohen's Kappa, Pearson's correlation coefficient and construct validity with categorical components, and One-Way Anova test. According to Cronbach's α coefficient (0.976) for total score, there was high internal consistency for the Ohkuma Dysphagia questionnaire. Test-retest reliability (Cohen's Kappa) ranged from 0.586 to 1.00, exhibiting acceptable stability. We also estimated the Pearson's correlation coefficient for the test-retest total score, which reached high levels (0.952; = 0.000). The One-Way Anova test in the two measurement times showed statistically significant correlation in both measurements ( = 0.02 and = 0.016). The adapted Greek version of the questionnaire is valid and reliable and can be used for the screening of dysphagia in the Greek-speaking patients.
大隈问卷是一种经过验证的筛查工具，最初用于检测日本护理机构住院患者的吞咽困难。本研究的目的是评估大隈问卷希腊语改编版的信度和效度。按照跨文化适应步骤，我们将经过验证的大隈问卷分发给70名患者（53名男性，17名女性），这些患者有的患有吞咽困难，有的没有。他们所有人都在一个月内再次完成了问卷。除9人外，我们对所有人进行了床边吞咽困难检查和视频荧光吞咽功能检查（VFSS），并要求参与者接受第二次VFSS筛查。统计分析包括用Cronbach's α系数测量内部一致性、用Cohen's Kappa测量信度、Pearson相关系数以及用分类成分测量结构效度，还有单向方差分析测试。根据总分的Cronbach's α系数（0.976），大隈吞咽困难问卷具有较高的内部一致性。重测信度（Cohen's Kappa）范围为0.586至1.00，显示出可接受的稳定性。我们还估计了重测总分的Pearson相关系数，达到了较高水平（0.952；P = 0.000）。两次测量时间的单向方差分析测试显示，两次测量均具有统计学显著相关性（P = 0.02和P = 0.016）。该问卷的希腊语改编版有效且可靠，可用于筛查说希腊语患者的吞咽困难。
