目的 探讨单胎妊娠妇女出生满意度和心理弹性在妊娠压力和产后压力间的链式中介作用，为采取针对性措施提供依据。 方法 便利抽样法选取南通市3所三级甲等医院门诊就诊的635名孕晚期女性为研究对象，采用妊娠压力量表、康诺-戴维森弹性量表，生育满意度量表-修订指标、产妇产后压力量表对其进行调查，并进行中介效应分析。 结果 单胎妊娠妇女产后压力总分与妊娠压力总分呈正相关（r=0.423），与出生满意度得分（r=-0.342）、心理弹性总分（r=-0.355）均呈负相关（均P＜0.001）。妊娠压力对产后压力的直接效应为8.709，出生满意度和心理弹性均在妊娠压力与产后压力间起部分中介效应，中介效应值为1.703和2.389。二者连续路径起链式中介效应，中介效应值为0.407。 结论 妊娠压力可直接或通过出生满意度和心理弹性间接作用于单胎妊娠妇女产后压力，医护人员应采取干预措施提高其出生满意度和心理弹性，降低产后压力。

Objective To explore the chain-mediated effect of birth satisfaction and psychological resilience on the relationship between pregnancy stress and postpartum stress in pregnant women with singleton pregnancy,in order to provide a reference for targeted intervention.Methods 635 women in their third trimester with outpatient examinations in three tertiary A hospitals in Nantong were selected by convenience sampling and surveyed with the pregnancy stress scale,the Connor-Davidson resilience scale,the birth satisfaction scale-revised indicator and maternal postpartum stress scale.A mediation effect analysis was then conducted.Results The analysis showed a positive correlation between the scores for postpartum stress and pregnancy stress（r=0.423）,and a negative correlation between the former and birth satisfaction（r=-0.342）and psychological resilience（r=-0.355）（all P＜0.001）.The direct effect of pregnancy stress on postpartum stress was 8.709,and both birth satisfaction and psychological resilience had a partial mediating effect between pregnancy stress and postpartum stress,with mediating effect values of 1.703 and 2.389,respectively.The continuous path between the two had a chain mediating effect value of 0.407.Conclusions Pregnancy stress can directly affect postpartum stress or do it indirectly through birth satisfaction and psychological resilience.Healthcare professionals should take intervention measures to enhance birth satisfaction and psychological resilience,thereby reducing postpartum stress.
