    Author: Carcamo M, Campo V, Behrmann D, Celedón C, Alvear Á, Vásquez P, Araya C.
    Journal: Rev Med Chil; 2018 May; 146(5):578-584. PubMed ID: 30148921.
    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.
