Abstract: Objective To classify the job burnout subtypes among medical staff and examine the predictive effects of emotional problems. Methods A total of 924 nurses and physicians were surveyed with Maslach Burnout Inventory-Human Service Survey, The Perceived Stress Scale, Generalized Anxiety Disorder, Patient Health Questionnaire and a self-developed demographic inventory. The data obtained were analyzed with SPSS 21.0 software. Results The job burnout fell into 4 subtypes: high job burnout(17.64%, HJB), moderate job burnout(30.74%, MJB), insufficient accomplishment job burnout(23.16%, IAJB)and low job burnout(28.46%, LJB). There were statistical differences in depression, anxiety and perceived stress among the 4 subtypes of burnout (P<0.05). Logistic regression model analysis showed that anxiety was a risk factor of HJB in contrast with the IAJB; perceived stress and shift work were risk factors of IAJB in contrast with MJB; anxiety, depression, perceived stress and shift work were risk factors of IAJB compared with LJB. Conclusion There are 4 subtypes of burnout among medical staff, including a special type called insufficient accomplishment job burnout. Special attention should be paid to both burnout and emotional problems for accurate interventions.
