ANDRADE, Alexsandro Luiz De; SOUZA, Marcos Aguiar de    PIRES, Pedro Paulo. The Brazilian version of the Three-Dimensional Work Fatigue Inventory (3D-WFI): adaptation and psychometric properties. []. , 21, 3, pp.1631-1637. ISSN 1984-6657.  https://doi.org/10.5935/rpot/2021.3.20563.

Work fatigue is the individual's perception of physical, cognitive, and emotional discomfort, associated with feelings of energy loss, tiredness, and exhaustion, leading to deleterious effects on work performance. This study aimed to adapt and raise psychometric evidence for the Brazilian context of the Three-Dimensional Work Fatigue Inventory (3D-WFI). The study was conducted with 455 adult workers from three occupational contexts (public safety, health, and general population). Among these, 251 were male. The data analyzed using confirmatory factorial and multigroup procedures indicated the original three-dimensional fatigue model (physical, cognitive and emotional). Accuracy indicators were good and above 0.91 in all resulting dimensions. External evidence of 3D-WFI was observed with work engagement, life satisfaction, and work-family conflict. Applications of the instrument for the context of research and diagnosis in organizations are discussed.
