Validation of the QLQ-CX24 questionnaire for the assessment of quality of life in Mexican women with cervical cancer


Objective Cervical cancer is the fourth most frequent neoplasm among women in terms of incidence and mortality. Health-related quality of life (HRQL) is an important outcome in oncology. The QLQ-CX24 instrument was developed to measure HRQL in patients with cervical cancer, and its Mexican-Spanish version had not been validated.

Methods Between March 2018 and May 2019, Mexican women older than 18, with any-stage cervical cancer were invited to participate in the study. Patients answered the QLQ-C30 and QLQ-CX24 questionnaires. Current tests for psychometric and clinical validation were performed.

Results Three hundred and thirty patients with cervical cancer were included in this study. All women invited to participate accepted and were included. The QLQ-CX24 internal consistency test demonstrated adequate convergent (Spearman correlation coefficient 0.001–0.847) and divergent validity (Spearman correlation coefficient <0.0001–0.45). Cronbach’s alpha coefficients of the three multi-item scales were >0.7 (minimum 0.76, maximum 0.89). Four scales of the QLQ-CX24 distinguished patients in different clinical stages. The evaluation of responsiveness demonstrated that the peripheral neuropathy scale was sensitive to change over time during chemo-radiation therapy. Six scales of the QLQ-CX24 instrument were associated with survival.

Conclusion The Mexican-Spanish version of the QLQ-CX24 questionnaire is reliable and valid for the assessment of HRQL in patients with cervical cancer.
