Objective To explore the relationship among willpower， stress perception and mental health of first aid officers in coal mine enterprises. Methods From April 2017 to May 2018， 193 first aid officers from some coal mine enterprises in Tangshan were selected. SymptomChecklist-90（SCL-90），Willpower Scale and Self-rating Stress Scale（SSQ-53）were used for questionnaire survey，and the data were analyzed. Results The scores of somatization factor（1.65±0.38）， obsessive-compulsive symptom factor（1.74±0.57），interpersonal relationship disorder factor（1.75±0.50） and psychotic factor（1.36±0.40） among first aid officers from some coal mining enterprises were higher than the national norms， and the differences were statistically significant（all P<0.05）. The willpower of first aid officers in coal mine enterprises was significantly negatively correlated with the total score of SCL-90， and the scores of somatization， obsessive-compulsive symptoms， interpersonal disorder， depression， anxiety， hostility， terror，paranoia， psychosis and other factors in SCL- 90 （r=-0.366， -0.227，-0.349，-0.268，-0.419，-0.304， -0.292，-0.299，-0.349， -0.289，-0.184， all P<0.05）.Willpower was negatively correlated with stress level and mental health level（r=-0.156，-0.349， both P<0.05）， while stress level was positively correlated with mental health（r=0.459，P<0.05）. The stress level had a strong mediating effect between willpower and mental health， and the total moderating effect between willpower and mental health was 18.56%.
