The aim of this study is the psychometric validation of a self-assessment questionnaire about swallowing disorders among adults, insisting on the validity of its content.
Created on the model of the "Voice Handicap Index", this questionnaire is composed of 30 statements on deglutition related aspects in daily life (5 point-rating scale). It is subdivided in three domains of 10 items: physical (S) (symptoms related to swallowing), functional (F) (nutritional and respiratory consequences) and emotional (E) (psychosocial consequences). Our first goal was to verify wether the different domains of the questionnaire were well related to what we wished to quantify or not. Therefore, regarding the domain S we compared the physiopathological mechanisms assessed by videofluoroscopy examination, for the domain F its results compared to the nutritional status and for domain E a scale of quality of life.
96 patients with dysphagia and 53 normal subjects were included in the study. The internal consistency reliability was correct (Cronbach's alpha= 0.9), For the domain S the difference between the normal subjects and the patients was statically significant. Our hypothesis regarding the domains were confirmed but not specifically. The domain S is related to the physiopathological mechanisms but also to the degree of severity. There are some correlations between the domain F and the nutritional status but also the results of the videofluoroscopy and the scale of quality of life. The domain E presents a fair correlation with the quality of life but it's related too much to physiopathological mechanisms, the duration of meal and the severity. As a conclusion, the results of this study allows to resume the validation without modification in the questionnaire. We are thinking, because of its similarity with the "Voice Handicap Index", to name it the "Deglutition Handicap Index".
本研究旨在对一份关于成人吞咽障碍的自我评估问卷进行心理测量学验证，重点关注其内容的有效性。
该问卷以“嗓音障碍指数”为模型创建，由30条关于日常生活中吞咽相关方面的陈述组成（5级评分量表）。它分为三个领域，每个领域10项：身体方面（S）（与吞咽相关的症状）、功能方面（F）（营养和呼吸方面的后果）以及情感方面（E）（心理社会方面的后果）。我们的首要目标是验证问卷的不同领域是否与我们想要量化的内容密切相关。因此，对于领域S，我们将其与通过电视透视检查评估的生理病理机制进行比较；对于领域F，将其结果与营养状况进行比较；对于领域E，则与生活质量量表进行比较。
96名吞咽困难患者和53名正常受试者纳入研究。内部一致性信度良好（克朗巴哈系数α = 0.9）。对于领域S，正常受试者与患者之间的差异具有统计学意义。我们关于各领域的假设得到了证实，但并非特别显著。领域S不仅与生理病理机制相关，还与严重程度有关。领域F与营养状况、电视透视检查结果以及生活质量量表之间存在一些相关性。领域E与生活质量呈现出一定的相关性，但它与生理病理机制、进餐时间和严重程度的关联过大。总之，本研究结果允许在不修改问卷的情况下继续进行验证。由于它与“嗓音障碍指数”相似，我们考虑将其命名为“吞咽障碍指数”。
