ABSTRACT
OBJECTIVES:
The Thyroidectomy-Related Voice Questionnaire (TVSQ) is a useful tool in the detection of voice changes and dysfunctions and the diagnosis of other symptoms related to transient or permanent laryngeal nerve damage in patients after thyroidectomy. The aim of our study is the translation and validation of (TVSQ) in the Greek language and in Greek population for the first time.METHODS:
The TVSQ was translated from English to Greek and vice versa by two independent researchers, while before the application of the TVSQ in clinical practice, a control group of 20 people was used. The following methods were used for the weighting and analysis of the TVSQ Polychoric correlation, Cronbach's alpha, confirmatory factor analysis, and item response theory (IRT).RESULTS:
Polychoric correlations revealed that questions 1-10 have a strong positive correlation with each other, while the correlation of the rest of the TVSQ items is positive. Subsequently, for the first subgroup of questions ("voice change") Cronbach's alpha was equal to 0.950, while for the second ("throat and neck discomfort") Cronbach's alpha was equal to 0.846. Thus, we conclude that the internal consistency reliability is high for both subgroups of TVSQ questions. With the IRT method we showed that for the first subgroup of questions ("voice change"), the item with the least predictive value is question 5, while for the second subgroup of questions ("throat and neck discomfort"), the item with the least educational value was question 15.CONCLUSIONS:
Our team translated and validated the TVSQ with the above statistical methods in the Greek language, so that it can be used as a valuable tool in clinical practice, and more specifically in patients undergoing thyroidectomy. TVSQ can play a significant role on the diagnosis of either postoperative voice disorders and other symptoms related to thyroidectomy.
