Resumen

CARCAMO, Marcela et al. Head and neck cancer: validation of the QLQ-H&N35 quality of life questionnaire. Rev. méd. Chile [online]. 2018, vol.146, n.5, pp.578-584. ISSN 0034-9887.  http://dx.doi.org/10.4067/s0034-98872018000500578.

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.
