Abstract：
Introduction Dysphagia is one of the general symptoms encountered in clinical practice. The impact of dysphagia can be devastating to a patient\'s physical condition and quality of life (QOL). To evaluate the QOL of patients with dysphagia there are numerous self-reported questionnaires. The most commonly used one such questionnaire is the Swallowing Quality-of-Life Questionnaire (SWAL-QOL). However, it is not concise and is incomplete as it does not address all the aspects of dysphagia. To overcome this, the Dysphagia Handicap Index (DHI) was developed. It focuses on the functional and emotional aspects in addition to the physical aspects of dysphagia. Objective To develop a Tamil version of the DHI (DHI-T) and assess its reliability, cultural adaptability and validity. Materials and method This cross-sectional study was conducted from May 2021 to December 2022 on 140 participants consisting of 70 dysphagia patients and 70 healthy individuals. Results The reliability and validity of the DHI-T were good with a high correlation between DHI-T and self-perceived severity scales of dysphagia. The mean total score in the Dysphagia group was 59.77 with the mean physical, functional and emotional scores being 23.86, 17.46 and 18.46 respectively. These scores were less compared to the Healthy group (p-value <0.01). Conclusion This study shows that DHI-T can be used as a reliable and valid tool to grade and study the different domains of dysphagia in our study population. Among the various causes of dysphagia studied in our population, it was noted that coronavirus disease 2019 (COVID-19)-related dysphagia patients had higher mean score in the emotional domain. To the best of our knowledge, the DHI scores for COVID-19-related dysphagia have not been done before. As the application of DHI in routine clinical practice and research is increasing, we believe this DHI-T can be of aid to Tamil-speaking patients.
摘要：
介绍吞咽困难是临床实践中遇到的一般症状之一。吞咽困难的影响可能对患者的身体状况和生活质量（QOL）造成毁灭性的影响。为了评估吞咽困难患者的QOL，有许多自我报告的问卷。最常用的一种此类问卷是吞咽生活质量问卷（SWAL-QOL）。然而,它不简明扼要，也不完整，因为它没有解决吞咽困难的所有方面。为了克服这一点，制定了吞咽困难障碍指数(DHI)。除吞咽困难的身体方面外，它还着重于功能和情感方面。目的开发泰米尔语版本的DHI（DHI-T）并评估其可靠性，文化适应性和有效性。材料和方法该横断面研究于2021年5月至2022年12月在140名参与者中进行，这些参与者包括70名吞咽困难患者和70名健康个体。结果DHI-T的信度和效度良好，DHI-T与自我感知的吞咽困难严重程度量表之间具有高度相关性。吞咽困难组的平均总分为59.77，功能和情感得分分别为23.86、17.46和18.46。与健康组相比,这些评分更低(p值<0.01)。结论本研究表明，DHI-T可作为一种可靠且有效的工具来对我们研究人群中吞咽困难的不同领域进行分级和研究。在我们人群中研究的吞咽困难的各种原因中，值得注意的是,2019年冠状病毒病(COVID-19)相关吞咽困难患者在情绪领域的平均得分较高.据我们所知,以前没有做过COVID-19相关吞咽困难的DHI评分.随着DHI在常规临床实践和研究中的应用越来越多，我们相信这个DHI-T可以帮助讲泰米尔语的患者。
