Mediating effects of psychological resilience between pregnancy stress and sleep quality in late pregnant women after perinatal loss
Objective To explore the mediating effect of psychological resilience between pregnancy stress and sleep quality in late pregnant women after perinatal loss.Methods A total of 610 women with pregnancy after perinatal loss were selected and a cross-sectional survey was conducted through general information questionnaire,Pregnancy Pressure Scale(PPS),Connor-Davidson Resilience Scale(CD-RISC)and Pittsburgh Sleep Quality Index(PSQI).Spearman correlation analysis and structural equation modeling were used to examine the correlation and mediating effect among pregnancy stress,psychological resilience,and sleep quality in late pregnant women.Results The total PPS score in late pregnancy women after perinatal loss was 0.60(0.37,0.97),which was in a state of moderate to high gestational stress;the total score of CD-RISC was 65.00(56.00,77.00),and the psychological resilience was at the medium level,and the total PSQI score was 7.00(5.00,9.00),of which 341(58.49％)pregnant women had a PSQI score≥7,indicating sleep disorder.Spearman correlation analysis showed that PPS score was positively correlated with PSQI score(P＜0.01),and negatively correlated with CD-RISC score(P＜0.01).CD-RISC score was negatively correlated with PSQI score(P＜0.01).The mediating effect analysis showed that psychological resilience played a partial mediating role between pregnancy stress and sleep quality,with the effect value of 0.121 accounting for 21.45％of the total effect.Conclusion Pregnancy stress can not only directly affect the sleep quality in late pregnant women after perinatal loss,but also indirectly affect the sleep quality through psychological resilience.
