It not only affects the physical and mental health of the mother, but also has an impact on the health of the fetus. Studies have shown that fear of childbirth has a significant positive predictive effect on prenatal depression. However, there are few studies exploring the underlying mechanism between fear of childbirth and depression.Methods: Childbirth Attitude Questionnaire, Social Support Rating Scale, Rumination Scale and Edinburgh Postpartum Depression Scale were used to measure 2765 Chinese pregnant women.Results: Fear of childbirth had a positive predictive effect on prenatal depression (β = 0.11, t = 15.63, P < 0.001); rumination played a partial mediating role in the influence of fear of childbirth on prenatal depression, with an indirect effect value of 0.05; social support not only moderated the impact pathway of childbirth fear on rumination (β = − 0.01, t = − 2.26, P < 0.01), but also moderated the impact pathway of rumination on prenatal depression (β = − 0.01, t = − 2.12, P < 0.01).Conclusion: Rumination mediated the relationship between fear of childbirth and prenatal depression, and social support had a moderating effect on the first and second half of the mediation model.Keywords: prenatal depression, fear of childbirth, social support, rumination, moderated mediation model |
