Abstract：Objective To explore the mental health status of medical personnel after occupa-tional exposure by establishing two-factor mental health model,in order to provide empirical evi-dence for accurate assessment and graded intervention in the future.Methods From October 2019 to October 2022,convenient sampling method was used to conduct a questionnaire survey on mental symptom self-rating scale and life satisfaction scale in 54 medical personnel with occupa-tional exposure in the Sixth People's Hospital of Xinjiang Uygur Autonomous Region.Confirmatory factor analysis(CFA)was performed to validate the two-factor model of mental health in medical personnel following occupational exposure.According to the classification of"four-point theory",the subjects were categorized into healthy,susceptible individuals,subhealthy,and individuals with psychological disorder.The life satisfaction and self-assessment of mental symptoms were compared among the four categories of individuals.Results The fit indices of the two-factor model for occupational exposure-related mental health among healthcare workers were superior to those of the single-factor model.In the two-factor model,the fit indices were as follows:x2/df=1.450,GFI=0.793,AGFI=0.690,NFI=0.884,CFI=0.960,and RMSEA=0.092.Among the participants,41 cases(75.93％)were classified as having complete mental health,7 cases(12.96％)as vulnerable,4 cases(7.41％)as partially symptomatic,and 2 cases(3.70％)as fully symptomatic.Statistically significant differences(both P＜0.01)were observed in life satis-faction and psychoticism scores across the four mental health categories.Conclusions The two-factor model of occupational exposure-related mental health in healthcare workers provides a com-prehensive distinction between mental illness and health,allowing for more specific classification of psychological states.Based on the status of positive mental health,limited resources can be al-located more rationally,enabling hospitals to implement more precise and effective interventions,thereby reducing the occurrence of psychological crises.
