Abstract:
Work fatigue represents an essential construct for understanding employee health and safety. In this study, we developed and explored the psychometric properties of a German version of the Three-Dimensional Work Fatigue Inventory and examined a set of hypothesized correlates of work fatigue. Data came from a sample of 439 German workers. Consistent with the original measure, confirmatory factor analyses supported a three-factor solution (physical, mental, and emotional work fatigue), and estimates of internal consistency reliability exceeded .90 for each dimension of work fatigue. The measure demonstrated a meaningful pattern of associations with predictors (time pressure, job control, psychological detachment, relaxation, and trait negative and positive affect) and an important outcome (work engagement). The German Three-Dimensional Work Fatigue Inventory will encourage research on an essential construct for employee health and safety using broader populations of workers.
