Perceived fatigue related to work has often been measured in one dimension. The main purpose of the present study was to validate a proposed five‐factor model of perceived fatigue in a new sample. 597 persons, employed in five occupations with different types of work loads, rated their fatigue after work. The ratings were subjected to analyses of linear structural equation models. The results suggest a slightly revised model for perceived fatigue, still with the five dimensions; Lack of energy , Physical exertion , Physical discomfort , Lack of motivation and Sleepiness . As expected, the rating profiles describing fatigue states differed between the five occupations. On the basis of these results, a revised version of the Swedish Occupational Fatigue Inventory (SOFI) is presented.
