Aim:
The aim of this study was to psychometrically validate the EORTC translated, Polish version of the EORTC QLQ-H&N35 questionnaire to support using it in the Polish clinical setting in patients with head and neck malignancies.
Materials And Methods:
Patients with histologically confirmed head and neck malignancies were included in the study. All patients filled in the Polish version of the EORTC QLQ-C30, the EORTC QLQ-H&N35 module, and a demographic questionnaire. Standardized validity and reliability analyses were performed.
Results:
During the recruitment period a total of 176 patients (82 females - 46.6%) were enrolled into the study, with a mean age of 54.3 ± 11.2 years. Cronbach alpha values ranged from 0.71 to 0.87. Satisfactory convergent and discriminant validity in multi-trait scaling analyses was seen.
Conclusions:
The Polish version of the EORTC QLQ-H&N35 module is a reliable and valid tool for measuring HRQoL in Polish patients with head and neck malignancies. It can be fully recommended for use in the Polish clinical setting.
