The Effect of Organizational Trauma on Employees' Mental Health: Moderating Role of Psychological Hardiness

Mental health is affected by many problems such as organizational trauma. Therefore, the aim of this study was to investigate the role of organizational trauma on nurses' mental health with the moderating role of psychological hardiness.
This research is a descriptive-survey study. The statistical population of the present research included nurses of some selected AJA hospitals, of which 162 nurses were selected by stratified random sampling method. For data collection, standard questionnaires of Dulaty and Deyhimpuor’ Organizational Trauma (2018), Gabedberg and Hiller’ Mental Health (1979), and Kiamarsi et al.’ Psychological Hardiness (1998) were used. Regression analysis and SPSS-22 software were used for data analysis.
 
The results showed that organizational trauma has a negative and significant relationship with mental health (β=-0.64, p<0.001), but the moderating role of psychological hardiness in the relationship between organizational trauma and mental health was not significant.
 
Based on the research results if we want decreasing the organizational trauma effect, it is recommended to address issues such as positive thinking training, increasing nurses 'life expectancy, and increasing perceived organizational support.
