Abstract
Introduction: the QOL-DYS is a self-report questionnaire that measures health-related quality of life in individuals with dysarthria. It is available in Italian, American English and European Portuguese. There is no version for Chilean Spanish that documents evidence of content validity. Objective: to determine the content validity of the QOL-DYS instrument, translated and transculturally adapted for Chilean users with dysarthria. Methods: instrumental study. A transcultural translation and adaptation of the questionnaire is carried out using the translation-backtranslation procedure and the items are modified based on the target population. Then, the formal quality, pertinence and relevance of the 40 item scale of the QOL-DYS are analyzed through expert judgment. Results: all statements have a relative frequency equal to or greater than 62.5%, when jointly analyzing the levels Agree and Strongly agree in the assessment by experts of formal quality, pertinence and relevance. Con- clusions: a version of the translated and adapted QOL-DYS for Chilean users with dysarthria is documented, with evidence of content validity. This study aims to promote the evaluation of the quality of life in users with dysarthria and promote instrumental studies in speech therapy.
