Background:One of the most important sources of tension in everyone's life is their job. The aim of this study is to determine the effect of stress management training using the PRECEDE model on the occupational tension of the pre-hospital emergency staff. Materials and Methods:This research is a quasi-experimental field trial controlled study that included emergency medical technicians from 115 emergency center for disaster management and 78 urban and road base in the Mazandaran University of Medical Sciences. According to the inclusion criteria, the subjects were randomly divided into two groups of intervention (n=65) and control groups (n=65). Data were collected using the stress factors questionnaire and questionnaire based on PRECEDE model. After the pretest, according to the results of the PRECEDE model-based instruction in 2 days, every 4 hours during 5 separate meeting it was.Results: After the training, the variables of predisposing, reinforcing, and enabling, and the behavior in the intervention group increased significantly (P<0.05) compared to the control group. The mean score of occupational tension in the intervention group reduced from 3.18 to 2.49. Conclusion:The findings showed that education based on PRECEDE model increases the predisposing factor (knowledge and attitude), reinforcing factor, and enhancer factor. These factors have the potential to affect the behavior more effectively. According to this, educational intervention based on PRECEDE model structures is effective on job stress and behavior. Researchers have suggested training on this pattern.
