title: Validation of the Polish version of the EORTC QLQ-CX24 module for the assessment of health-related quality of life in women with cervical cancer.
abstract: The aim of our study was to undertake a prospective validation study of the Polish version of the EORTC cervical cancer (EORTC QLQ-CX24) module used alongside the EORTC core measure. The translated module was pilot-tested according to the established EORTC guidelines. Patients with histological confirmation of cervical cancer were eligible for the study. All patients filled out the Polish version of the EORTC QLQ-CX24 module in addition to EORTC QLQ-C30 and a demographic questionnaire. Standardised validity and reliability analyses were performed. One hundred and seventy-one patients were enrolled into the study, mean age ± SD: 52.1 ± 9.6. Cronbach alpha coefficients, range 0.81-0.88, showed positive internal consistency. Re-test was undertaken with 40 patients (23.4%). Interclass correlations for the EORTC QLQ-CX24 ranged from 0.85 to 0.89 and proved appropriate test-retest reliability. Satisfactory convergent and discriminant validity in multi-trait scaling analyses was seen. Concluding, the Polish version of the EORTC QLQ-CX24 module is a reliable and valid tool for measuring HRQoL in patients with cervical cancer. It can be fully recommended for use in clinical and epidemiological settings in the Polish population.
