Background and Objectives: Studies of the relationship between personal qualities and job consequences usually find poor and inconsistent correlations; the reason may lie in the ignorance of some modifying factors mediating such relationship. The perceived control has attracted much attention as a candidate factor. This study aimed to examine the mediating role of perceived control in the impact of agreeableness and neuroticism on job stress in hospital staff. Methods: A conceptual model was developed, in which neuroticism and agreeableness were considered as the independent variables, perceived control as the mediating variable, and job stress as the dependent variable. The research population included all staff of Imam Reza Hospital in Uromia (Iran); of whom, 248 were selected using random sampling. Using Morgan Table, the final sample size of 248 was achieved. Neuroticism and agreeableness were assessed through NEO’s big-five-factor inventories. Perceived control was evaluated using Tetrick and Larocco questionnaire [41]. Job stress was measured by the scale developed by House and Rizzo. The conceptual model was fitted to the data using the structural equation modeling technique. Findings: Agreeableness showed a significant positive correlation with job stress and a significant negative correlation with perceived control. Conclusions: The findings suggest that causal impact of personality traits on job stress is mediated through the perceived control.
