Article Synopsis

The EORTC QLQ-C30 is a widely used quality of life questionnaire in cancer research that measures various functional and symptom scales but shows high item correlations, indicating reduced dimensionality.
The study aimed to evaluate the dimensionality of the QLQ-C30 using item response theory (IRT) and confirmatory factor analysis (CFA) by analyzing responses from 1,107 lung cancer patients from clinical trials.
Results indicated that the QLQ-C30 operates as a unidimensional scale for perceived quality of life, confirmed through statistical models showing adequate item responsiveness and overall scale fit.
