Objective:
The aim of this study was to evaluate patients' acceptance and the reliability and validity of a recently developed instrument to assess quality of life among cervical cancer patients, the European Organization for Research and Treatment of Cancer Cervical Cancer Module (EORTC QLQ-CX24), in surgically treated patients after primary surgery.
Methods:
The EORTC QLQ-CX24 was administered to 134 cervical cancer patients who had undergone pelvic surgery. Additional questionnaires completed were the EORTC QLQ-C30, and the Hospital Anxiety and Depression Scale. Sociodemographic and medical data were recorded.
Results:
Missing values occurred in 4.5% of all non-optional items. Internal consistencies (Cronbach's alpha coefficients) for the three multi-item scales ranged from 0.70 to 0.87 (Symptom Experience 0.70, Body Image 0.87, Sexual/Vaginal Functioning 0.76), whereas scaling errors occurred in 6.8%, 0.0%, and 6.3% of the cases. In all domains, the entire range of the scale was used by patients. The scales were able to discriminate between different subgroups of patients.
Conclusion:
These psychometric analyses confirm that the EORTC QLQ-CX24 is a useful tool for the assessment of quality of life in cervical cancer patients after surgery.
