Objective Aviation is one of the occupations with the most serious stress.Feeling of job pressure is an intervening variable between job stress and stress reaction.Personality plays an important role in stress defense.So in the study,we examined the relationship between feeling of job pressure and personality among the pilots in order to provide guidance for the study and intervention of occupational stress.Methods A total of 166 pilots,including 67 fighter pilots,36 helicopter pilots,44 helicopter student pilots and 19 transporter pilots,were examined with job stress questionnaire(JSQ),rivised Eysenck personality questionnaire-short scale for Chinese(EPQ-RS),aviation safety locus of control inventory(ASLOCI)and hardy personality questionnaire(HPQ).The relationship between feeling of work pressure and personality was analyzed.Results The coefficient of internal consistency of JSQ is 0.710 which is acceptable in psychometrics.The ANOVA indicates that the difference between lack of control and JSQ sub-dimension scores among different plane groups is of statistic significance(P<0.05).JSQ negatively correlates to EPQ-E,HPQ and ASLOCI total score respectively(r=-0.402,-0.480,-0.409,P<0.01),and positively correlates to EPQ-N and external control dimension score of ASLOCI(r=0.543,0.375,P<0.01).Conclusion JSQ is an acceptable measurement in pilots.There is difference in job stress among pilots on different aircrafts.External control and emotionally unstable pilots are prone to have high level of job stress while internal control,extrovert and hardy individuals may feel less job stress.All results can be used in guiding job stress study and intervention among pilots.
