Abstract: Objective To investigate the mental health status and influencing factors of patients with occupational pneumoconiosis in different stages. Methods A retrospective analysis was performed for the relevant data of 57 patients with pneumoconiosis（pneumoconiosis group） and 724 healthy adult males（normal group） hospitalized in the Department of Occupational Pulmonology of Shandong Academy of Occupational Health and Occupational Medicine from January to December 2022,and the mental health status and influencing factors of pneumoconiosis patients were investigated by Symptom Checklist-90,coping style questionnaire,modified British medical research council（mMRC） score and general condition questionnaire. Results The total score and the scores of the following factors in the pneumoconiosis group were higher than those in the normal group. The differences of total score of SCL-90[（174.61±64.77）vs（129.96±38.76）points],the scores of somatization factor[（2.45±0.86）vs（1.38±0.49）points],obsessive-compulsive factor[（2.09±0.85）vs（1.66±0.61）points],depression factor[（1.98±0.82）vs（1.51±0.6）points],anxiety factor[（1.97±0.84）vs（1.41±0.44）points],hostility factor[（1.82±0.78）vs（1.48±0.56）points],terror factor[（1.63±0.75）vs（1.23±0.37）points] and psychoticism factor[（1.72±0.67）vs（1.32±0.44）points] were statistically significant（all P<0.05）. The total score of SCL-90 and the scores of various factors in patients with pneumoconiosis were not correlated with the score of mMRC score（P>0.05）. Age（OR=1.090,95%CI：1.004-1.184,P<0.05） and negative coping style（OR=8 007.941,95%CI：60.453-1 060 780.289,P<0.01） were risk factors for psychological abnormalities. Conclusion The mental health level and coping methods of patients with pneumoconiosis are worthy of attention,while the mental health level of patients with pneumoconiosis who adopt passive coping methods is poor.
