Sensitivity to change of the EORTC quality of life module measuring cancer‐related fatigue (EORTC QlQ‐Fa12): Results from the international psychometric validation

Abstract

The European Organisation for Research and Treatment of Cancer Quality of Life Group (EORTC QLG) has developed a multidimensional instrument measuring cancer‐related fatigue, the EORTC QLQ‐FA12. The analysis of sensitivity to change is an essential part of psychometric validation. With this study, we investigated the EORTC QLQ‐FA12 s sensitivity to change.
