Psychological aggression perpetrated by customers, coworkers, and supervisors is a behavior frequently experienced in the workplace with negative consequences for an individual's health. The aim of this systematic review was to examine the personal outcomes of overt workplace psychological aggression and summarize empirical evidence on how to prevent and reduce its effects. A search on PubMed, Scopus, ProQuest, and Web of Science electronic databases was made. Data were obtained from 30 studies (26 cross-sectional, 3 longitudinal, 1 quasi-experimental) representing 20,683 employees. Longitudinal studies indicated that workplace psychological aggression is significantly associated with musculoskeletal injury and psychological strains (anxiety, depression, anger) over time. Research also suggests that psychological aggression at work predicts fear, emotional exhaustion, depersonalization, personal accomplishment, and physical symptoms, for example. Additionally, the information collected suggested that support from coworkers, supervisors, and management; informational support; political skills; job resources; and confidence to prevent and respond to aggression moderate significantly the impact of workplace psychological aggression on personal and organizational outcomes. Perceptions of a violence-prevention climate, aggression-preventive supervisor behavior, and aggression-preventive employee effort are also significantly associated with a reduction in psychological aggression at work and strains. In conclusion, this review allows us to understand the effects of the psychological aggression by identifying the preventive strategies that could be adopted by managers, supervisors, or leaders to deal with it and promote individual's health in the workplace.
