Abstract
Background: Head and neck cancer affects esthetic and anatomical parameters, causing pain and functional impotence, affecting vital functions such as eating and breathing, hampering the quality of life of patients. EORTCQLQ- C30 questionnaire with its supplementary module QLQ-H&N35 evaluates the quality of life of these patients. Aim: To statistically validate the QLQ-H & N35 questionnaire in patients with head and neck cancer. Material and Methods: In a cross-sectional study, we studied patients with head and neck cancer who attended a rehabilitation unit. Reliability was measured using Cronbach’s α and validity was determined by the diagnostic efficiency of the QLQ-H&N35 scale as compared with the SF-36 quality of life survey. A Receiver Operational Characteristic (ROC) curve was generated. Results: The Cronbach’s α global internal consistency of the questionnaire was > 0.70 and its discrimination capacity was 74.2%, which are considered acceptable. Conclusions: These results confirm the statistical validity of the QLQ-H&N35 questionnaire, specifically for patients with head and neck cancer in Chile.

Bibliographical note
Funding Information:Es así como la Organización Europea para Investigación y Tratamiento del Cáncer (EORTC) ha desarrollado diversos cuestionarios específicos de calidad de vida que se consideran completos y su formulación resulta culturalmente próxima a la idiosincrasia latina. La EORTC ha estructurado un cuestionario en base a 30 preguntas medidas mediante escala Likert, aplicable a todo paciente oncológico, ya adaptado culturalmente y valida-do en Chile16. Dentro de este cuestionario, existe como módulo suplementario el QLQ-H&N35 para pacientes con CCC, que ha sido traducido a su versión en español, siendo validado por Arrarás et al (2001) en España. Esta versión ha sido modi-ficada para su aplicación en la población chilena, sin embargo, no se ha validado estadísticamente en Chile.
