Objective:To explore the relationship and mechanism among job stressors, perceived professional benefits and humanistic practice ability in midwives, so as to provide reference for the training and management of midwives.Methods:Used the convenient sampling method to conduct a cross-sectional survey on 216 midwives in 6 comprehensive or specialized hospitals in Zhejiang Province by using Stressor Scale, Perceived Professional Benefits Questionnaire and Humanistic Practice Ability Scale from May to September 2020. The mediating effect was analyzed on the basis of the current situation analysis and correlation analysis.Results:The total scores of humanistic practice ability, job stressors and perceived professional benefits of midwives were (102.13 ± 25.91), (72.77 ± 14.49) and (138.23 ± 18.71) respectively. The job stressors of midwives were negatively correlated with humanistic practice ability ( r=-0.206, P<0.01), perceived professional benefits were positively related to humanistic practice ability ( r=0.289, P<0.001) and were negatively correlated with job stressors ( r=-0.507, P<0.001). Perceived professional benefits played a major mediating role in the influence of stressors on humanistic practice ability (the total standardized effect was -0.233, and the indirect effect was -0.144). Conclusions:Perceived professional benefits act as a main mediator between job stressors and humanistic practice ability in midwives. Managers should reduce job stressors, enhance perceived professional benefits, and promote the formation, development and practice of humanistic practice ability of midwives.
