BACKGROUND
This study is to evaluate swallowing problems (dysphasia) in multiple sclerosis (MS) patients; the importance of using tools that are durable and appropriate is well understood. One of the most trusted tools is the dysphagia in multiple sclerosis (DYMUS) test. The aim of this study was to prepare a Persian version and to evaluate the validity and reliability of the test.
MATERIALS AND METHODS
This methodological study was conducted on 236 MS patients in Southeast of Iran from August 2015 to February 2016. After translation and cultural adaptation of the test in Persian, the validity of this test was determined using expert opinions accordance with the International Quality of Life Assessment Project. In addition, exploratory factor analysis (EFA) was performed with varimax rotation. The confirmatory factor analysis (CFA) was conducted and the goodness of fit indices was calculated. Moreover, to test the reliability, Cronbach's alpha coefficient and intraclass correlation coefficient (ICC) were used.
RESULTS
In total, 236 MS patients were included in the study (81 males and 155 females). All the questions in the test's Persian version obtained an acceptable face and content validity (content validity ratio = 1, Scale content validity index/Ave = 1). EFA revealed that the scale has two factors (solid-liquid) with 67.5% cumulative variance. CFA indicated a good fit to the intended two-factor structure, and the ratio of Chi-square to the degree of freedom was 1.79, and the root mean square error of approximation was 0.058. The internal consistency of total test indicated the appropriate level (Cronbach's alpha coefficient = 0.775), and test-retest reliability total questionnaire was found to be ICC = 0.985, indicating its high reliability.
CONCLUSION
The results of this study indicated that the Persian version of the DYMUS questionnaire had good reliability and validity for patients with MS.
背景
本研究旨在评估多发性硬化症（MS）患者的吞咽问题（吞咽困难）；使用耐用且合适工具的重要性已得到充分理解。最值得信赖的工具之一是多发性硬化症吞咽困难（DYMUS）测试。本研究的目的是编制波斯语版本并评估该测试的有效性和可靠性。
材料与方法
本方法学研究于2015年8月至2016年2月在伊朗东南部的236例MS患者中进行。在将测试翻译成波斯语并进行文化调适后，根据国际生活质量评估项目，利用专家意见确定该测试的有效性。此外，进行了具有方差最大化旋转的探索性因子分析（EFA）。进行了验证性因子分析（CFA）并计算了拟合优度指标。此外，为测试可靠性，使用了克朗巴哈α系数和组内相关系数（ICC）。
结果
本研究共纳入236例MS患者（81例男性和155例女性）。测试波斯语版本中的所有问题均获得了可接受的表面效度和内容效度（内容效度比=1，量表内容效度指数/平均值=1）。EFA显示该量表有两个因子（固体-液体），累积方差为67.5%。CFA表明与预期的双因子结构拟合良好，卡方与自由度之比为1.79，近似均方根误差为0.058。总测试的内部一致性表明处于适当水平（克朗巴哈α系数=0.775），重测信度总问卷的ICC为0.985，表明其可靠性高。
结论
本研究结果表明，DYMUS问卷的波斯语版本对MS患者具有良好的可靠性和有效性。
