Objective: To analyze the influence of intrinsic motivation on work burnout and the mediating effects of work stress. Methods: In 2020, questionnaire survey was conducted in 1 655 gastroenterologists working in 28 provinces of China. Mediation model was used to analyze the mediating effects of work stress in the relationship between intrinsic motivation and burnout. Resutls 1655 valid questionnaires were collected, including 1 132 women and 523 men, with an average age of 39.26. Intrinsic motivation was related to reduced level of burnout, including emotional exhaustion, dehumanization and low sense of accomplishment (β=-2.06, -1, 77 and-4.20;P<0.001). Job stress partially mediated the negative correlation between intrinsic motivation and job burnout in three dimensions, accounting for 40%, 15% and 5% (β=-1.58, -0.36 and-0.21;P<0.05), respectively. In female physicians, the intrinsic motivation was more directly related to the reduction of burnout, especially in the dimension"emotional exhaustion"(direct effect accounting for 62% in female gastroenterologists and 46% in male). Conclusions: Enhancing the intrinsic motivation of gastroenterologists can directly reduce burnout and indirectly reduce burnout by alleviating work stress. In the same work environment, female physicians' intrinsic motivation had a greater and more direct effect on reducing burnout.
目的： 分析中国医院消化科医师内在工作动机对职业倦态的影响以及工作压力的中介作用。 方法： 2020年调查28个省份331家三级医院消化科医师1 655名，采用中介效应模型分析工作压力在内在动机与职业倦态关系中的作用。 结果： 调查收回有效问卷1 655份，女1 132名，男523名，调查对象平均年龄39.26岁。内在动机对职业倦怠三个维度——情感耗竭、去人性化、低成就感均有降低作用（β=-2.06、-1.77、-4.20，均P<0.001）；工作压力在内在动机和职业倦怠三个维度（情感耗竭、去人性化和低成就感）的负相关性中均起部分中介作用，中介效应占比分别为40%、15%和5%（β=-1.58、-0.36、-0.21，均P<0.05）；女性医师的内在动机更多地直接降低了职业倦态，特别是在情感耗竭维度，直接效应占比为62%，高于男性医师中46%的直接效应占比。 结论： 加强和利用消化科医师的内在动机既可直接降低职业倦态，也能通过缓解工作压力间接降低职业倦态；在同样环境中，女性医师对工作的内在动机对降低职业倦态有更大和更直接的作用。.
