Process / pipelineFive-Dimensional Fatigue Assessment
Multidimensional Fatigue Inventory (MFI-20)
The Multidimensional Fatigue Inventory is a 20-item self-report instrument that comprehensively measures five distinct dimensions of fatigue: general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue. Developed by Smets and colleagues in 1995, the MFI-20 is grounded in a theoretical model distinguishing fatigue phenomenology from behavioral and cognitive consequences, making it particularly valuable for research examining fatigue mechanisms and interventions targeting specific fatigue dimensions.
