Psychometric properties, factor structure, and German population norms of the multidimensional fatigue inventory (MFI-20).

ABSTRACT:

Objective

The Multidimensional Fatigue Inventory (MFI-20) is commonly used, but its factor structure remains unclear. The MFI-20 consists of five subscales (general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue). This study investigates the psychometric properties, including the factor structure, of a general German population sample and tests group hypotheses on gender and age. Another objective is to provide normative data by gender and age groups.

Methods

Using data from a representative German sample (n=2,509), reliability and convergent validity measures, group hypothesis testing, and confirmatory/exploratory factor analyses were conducted.

Results

The MFI-20 demonstrated satisfactory internal consistency and showed adequate
