Abstract
The impacts of cancer and its treatment can be measured by indicators of quality of life using the EORTC QLQ C-30 questionnaire. A cross-sectional study was done on 30 patients in Sanglah Hospital Denpasar. Data were collected through purposive sampling of patients who fit the inclusion criteria: women who were 30–70 years old were diagnosed with gynecological cancer, had chemotherapy in Sanglah Hospital, and had agreed to be part of the research by signing the informed consent form. Patients who were unable to rationally communicate became part of the exclusion group in this research. Validity and reliability of the tools in this study were tested using confirmatory factor analysis with STATA ®version 12. Confirmatory factor analysis indicates that all items have a loading factor ( )> 0.70 so that it can be said that all the questions are valid. Reliability items have the value > 0.50 for all questions which shows all questions are reliable. Construct validity of the results of the calculation produce a value VE = 0.90 and the reliability construct (RF) of 1, which meet both validity and reliability constructs. Questionnaire EORTC QLQ C-30 as a measurement of the quality of life of gynecological cancer patients in Sanglah Hospital are valid and reliable.
