Abstract: Objective To explore the correlation between personality traits and coping styles of navy soldiers onescort at the Gulf of Aden. Methods In June 2021,the Eysenck personality questionnaire-r short scale Chinese（EPQ-RSC） and the coping style questionnaire（CSQ） were used to perform a questionnaire survey on 157 navy soldiers from a troop,who had just participated in the Gulf of Aden escort. And the data were analyzed. Results Among the factors of coping style,the scores of problem solving and seekinghelp were significantly higher than the Chinese military norms（both P<0.01）,while the scores of self-accusation,fantasy, avoidance and rationalization were significantly lower than Chinese military norms（all P<0.01）. The neurotic dimension of personality traits was significantly correlated with the scores of dimensions of coping styles,the extroversion-introversion dimension was significantly correlated with the scores of the problem solving,seeking help and self-blame dimensions of coping styles,the psychic dimension was significantly correlated with the the scores of problem solving,seeking help dimensions of coping styles,and the lying dimension was significantly correlated with the scores of self-blame,fantasy,withdrawal and rationalization dimensions of coping styles（all P<0.05）. The regression analysis results showed that the personality traits of navy soldiers werethe important factor affecting their coping style. The psychoticism level of navy soldiers significantly positively predicted rationalized coping（β=18.050,P<0.01）,extroversion-introversion level positively predicted problem solving coping（β=3.680,P<0.01） and seeking help coping（β=1.740,P<0.05）,and neuroticism level significantly positively predicted self-blame coping（β=5.480,P<0.01）. Conclusion The personality traits and coping styles are highly correlated among the navy soldiers on the escort,those with higherextraversion levels are more likely to choose mature coping styles,those with higher psychoticism levels tend to choose mixed coping style,and those with higher neuroticism levels are prone to respond immaturely.
