Preliminary data on the Multidimensional Fatigue Inventory-20 from female caregivers of male hemodialysis patients.

To test the reliability and concurrent validity of the Multidimensional Fatigue Inventory-20, 45 spouses or first-degree female caregivers of male hemodialysis patients in northern and eastern Iowa were administered the Multidimensional Fatigue Inventory-20 and the Rhoten Fatigue Scale. Four of the five subscales had a high Cronbach alpha (.76 to .82). There were low to moderate statistically significant Pearson correlations between scores on the Rhoten Fatigue Inventory and the MFI-20 subscales (.40 to .72). Limitations of generalizations are addressed.
