Current psychosocial risk theories focus on different dimensions that it is necessary to understand each theory and approach to be able to adequately be analysed any psychosocial risk problem. Psychosocial hazards and risk, along with their relevant significant impacts, are often unrecognized by workers and management. This leads to increasing number of occupational accidents that are partly caused by psychosocial factors, in addition to physical, chemical, biological, and biomechanical factors. This review aims to obtain an in-depth understanding of the approaches/theories/models that are necessary to be able to comprehensively explain how psychosocial hazards and risk occur and their related impacts against workers in a workplace.
