Objective To investigate the status of occupational lassitude among doctors in a hospital of Chinese People’s Armed Police Forces. Methods 145 doctors were randomly assessed by MBI-GS Scale. The doctors’ lassitude levels were analyzed descriptively. Independent sample t-test was used for different doctors. General liner model was used to describe difference among doctors in different department, seniority and professional title. Results ①The doctors’ emotional exhaustion and depersonalization dimension reached moderate level; however, reduced personal accomplishment (RPA) score was low(P<0.05).②ED and RPA scores in surgeons and obstetricians were higher than those in non-clinical doctors. ③There was no difference in technical post and seniority.
