Abstract
Purpose: To achieve a cross-cultural equivalence of the Chilean version of the V-RQOL protocol, through its cultural and linguistic adaptation. Methods: First, two bilingual speech therapists made a translation of the V-RQOL into Spanish. Second, a back-translation to English was performed by a speech therapist who did not participate in the previous stages. Then, a comparison between the original and the back-translation versions of the test was conducted. The existing discrepancies were modified by a committee of five speech therapists, translating the name of the Voice-Related Quality of Life (V-RQOL) instrument into Spanish as Medición de la Calidad de Vida en Relación a la Voz (MCV-RV), with 10 questions and 5 possible answers for each. In order to analyze cultural equivalence, the protocol was applied to 15 individuals with voice disorders. For each question, a ‘Not applicable’ option was added to the possible answers to determine which questions were not clearly understood by the individuals being tested. Two of the assessed individuals had difficulties in answering a distinct question, though only one of these two questions was modified. The final version of MCV-RV protocol was applied to five individuals with voice disorders who had no difficulty understanding the questions properly. Results: The MCV-RV reflects the original English version, both in the number and types of questions (including physical functioning and the social-emotional aspects). Conclusion: A cross-cultural equivalence of the V-RQOL was achieved, thereby creating an adapted Chilean-Spanish version (MCV-RV). The validation of the MCV-RV protocol for Chilean Spanish is currently in progress.

Resumen
Objetivo: Lograr la equivalencia cultural de la versión Chilena del Protocolo V-RQOL, a través de su adaptación cultural y lingüística. Método: Primero, dos Fonoaudiólogos bilingües realizaron una traducción de V-RQOL al español. En segundo lugar, una Fonoaudióloga que no participó en las etapas previas, realizó una retrotraducción al inglés. Luego, se efectuó una comparación entre la versión original y la versión retrotraducida. Las discrepancias fueron modificadas por un comité de cinco Fonoaudiólogos, traduciendo el nombre al español como “Medición de la Calidad de Vida en Relación a la Voz” (MCV-RV) “, con 10 preguntas y 5 opciones de respuesta. Para la equivalencia cultural, se aplicó el protocolo a 15 personas con trastornos de voz. Para cada pregunta, se agregó la opción “No aplicable” entre las alternativas de respuesta con el fin de identificar preguntas incomprendidas o inapropiadas por la población. Dos de los sujetos evaluados tuvieron dificultad para responder dos preguntas diferentes, así que fue modificada solo una de ellas. La versión final del protocolo MCV-RV se aplicó a cinco personas con patología vocal, sin dificultades para comprender las preguntas adecuadamente. Resultados: La MCV-RV refleja la versión original en inglés, tanto en número como en tipos de preguntas (incluido el funcionamiento físico y aspectos socioemocionales). Conclusiones: Existe adaptación cultural de V-RQOL para el español Chileno (MCV-RV). La validación del MCV-RV para el español de Chile está actualmente en curso.
