Methods A questionnaire survey using the Chinese Perceived Stress Scale (CPSS) and Tennessee Self-Concept Scale (TSCS) was conducted among 285 pre-hospital emergency medical workers from 20 emergency centers in Jining and Heze cities, Shandong Prrovince, 86 physicians and 199 nurses, 195 males and 90 females, aged (29.56 ± 6.38)(21~52), 247 married and 38 unmarried, with the diplomas of technical secondary school (n=37), junior college (n=83), or university (165), and with the primary professional title (n=93), middle title (150), or high title (42). Results (1) The total score of CPSS of the pre-hospital emergency medical workers with health risk pressure was 3 (1.81 ± 7.35), significantly higher than that of the the pre-hospital emergency medical workers without health risk pressure [20.25 ± 6.54, t=13.766 , P<0.01]. The total score of self evaluation of the pre-hospital emergency medical workers with health risk pressure was (229.38 ± 21.48), significantly lower than that of the pre-hospital emergency medical workers without health risk pressure [(266.49±26.29), t=12.301, P<0.01]. Correlation analysis showed that the total TSCS score was negatively correlated with the total CPSS score(r=-0.475,P<0.01). Conclusion Psychological stress is an important factor influencing self-concept, and relieving the psychological stress helps maintain the psychological health of pre-hospital emergency medical workers.
