Moreover, the necessity to increase productivity and flexibility resulted in longer hours of work and shorter rest periods followed by the irregular working time. One of the consequences of this workload is fatigue (1). Fatigue is one of the most important problems affecting several aspects of human life (2, 3). It is a serious issue in transportation and industrial safety studies (4).

There is a need to utilize useful instruments, such as self-reported scales to understand fatigue and its relative factors and causes. The purpose of this study was to identify and present useful self-reported scales to measure fatigue. Materials and Methods: Data were extracted from databases, such as ISI Web of Science, Scopus, and Science Direct, and the search was undertaken considering a 22-year period (1996-2018). The search scope of this study was in ergonomics and the health outcomes and the language of the elected scales were in English. The articles that used objective fatigue scales or subjective scales for sleep-related studies were excluded from the review. Screening and appraisal of 12540 articles resulted in 115 articles being included in this review. Results: According to the obtained results, the details of 12 self-reported fatigue scales were reported in this survey. These scales are divided into two groups, namely unidimensional (n=5) and multidimensional scales. The Brief Fatigue Inventory scale is the shortest form of the scales in this study. However, Multidimensional Fatigue Symptom Inventory and Swedish Occupational Fatigue Inventory scales evaluate five aspects of fatigue using more items. In total, 6 items in these scales measure fatigue among working population. Conclusion: There are several scales with acceptable validation to distinguish and measure fatigue during studying or working.
