Research on the Impact of Perceived Stress on Prenatal Depression Among Pregnant Women
Objective To explore the relationship and mechanisms between perceived stress and prenatal depres-sion among pregnant women.Methods Convenient sampling was employed to select 1055 pregnant women from outpatient clinics of four tertiary A hospitals in Guangzhou from June 2020 to January 2021.The Edinburgh Postna-tal Depression Scale,Perceived Stress Scale,Ruminative Response Scale and Emotional Regulation Questionnaire were used for investigation.Results The detection rate of prenatal depression among 1055 pregnant women was 37.53％.Prenatal depression was positively correlated with perceived stress and rumination(r=0.308,0.554,all P＜0.01),and negatively associated with cognitive reappraisal(r=-0.183,P＜0.01).Rumination played a media-ting role between perceived stress and prenatal depression,accounting for 58.71％of the total effect.Cognitive reap-praisal played a moderating role on the mediating role of rumination(P＜0.01).When cognitive reappraisal levels were high,the indirect predictive effect of perceived stress on prenatal depression was weaker(β=0.652,0.222,all P＜0.01),and vice versa(β=0.987,0.291,all P＜0.01).Conclusions The perceived stress can directly or indirect-ly influence prenatal depression through rumination,and is moderated by cognitive reappraisal among pregnant women.In clinical practice,targeted prenatal depression interventions can be conducted by enhancing the cognitive reappraisal levels of pregnant women and reducing rumination.
