Abstract: ObjectiveTo evaluate the sub-health status among doctors with a high order factor model.MethodsTotally 810 doctors were selected with stratified cluster random sampling and investigated with a sub-health scale.ResultsThe sub-health status could be attributed to four factors:psychological,physical activity,physical function,and social adaptation.The results showed a strong correlation among them(correlation coefficient:0.78-0.92,P<0.001).A high order factor could recapitulate these four factors,and the factor loading was 0.95,0.97,0.87,and 0.88,respectively.The subhealth scores in female doctors were higher than those in male doctor,and the sub-health scores for the doctors at the age of 30-45 years were higher than those at other ages.ConclusionHigh order factor model can be applied to evaluate doctors's sub-health status.
