This study focuses on the relationship between job stress and intention to leave among obstetric (OB) nurses in the context of China‘s birth policy adjustment, and provides a scientific basis for policymakers and healthcare administrators. This study used a non-experimental descriptive correlation design with a purposive sampling of 230 OB nurses from three tertiary hospitals in Jinan, Shandong Province. Participants were surveyed using three questionnaires and descriptive analysis; ANOVA and correlation analyses were used to analyze the relationship between participants‘ stressor levels and turnover intention. Pearson‘s correlation coefficient analysis showed that there was a positive correlation between nurses‘ work stressors and turnover intention, with a correlation coefficient of r = 0.53, a moderate positive correlation (P < 0.001). Based on the survey data from three tertiary hospitals in Shandong Province, the obstetric nurses group has a medium level of work stressors, but a high turnover intention, highlighting the professional identity crisis.
