| Abstract: | Background: Impairment of voice and swallowing after thyroidectomy can negatively affect communication, eating and overall quality of life. The Thyroidectomy-Related Voice and Symptom Questionnaire was developed to facilitate the early identification and monitoring of voice and swallowing outcomes in patients who have undergone thyroidectomy. While it has been translated and culturally adapted to Brazilian Portuguese, there is currently no evidence supporting its construct validity. Aim: To examine the construct validity of the Brazilian Portuguese version of the Thyroidectomy-Related Voice and Symptom Questionnaire (BR-PT-TVSQ). Methods and Procedures: This cross-sectional study included 395 Brazilian individuals undergoing thyroidectomy, mainly female (95.2%), with a mean age of 41.38 ± 11.12 years. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to test the structural validity of the 20-item BR-PT-TVSQ. Internal consistency was assessed using Cronbach's alpha. Convergent and discriminant validity were analysed through internal correlations. Outcomes and Results: The EFA suggested a three-factor model with a Cronbach's alpha of 0.947. The CFA confirmed the three-factor model with acceptable goodness-of-fit indices: Factor 1 = voice symptoms; Factor 2 = oropharyngolaryngeal symptoms and Factor 3 = cervical and thoracic discomfort. All three factors presented significant convergent validity. The discriminatory power between Factors 2 and 3 was smaller than in other comparisons. Conclusions and Implications: The BR-PT-TVSQ provided evidence of construct validity for a three-factor model with acceptable structure, convergent and discriminant validity. These sources of validity evidence are crucial to clinically ensure that the TVSQ-PT-BR structure accurately represents the investigated outcomes. |
