Objective: Exploring the mediating effect of perceived social support between the maternal personality traits and pregnancy-related anxiety. Methods: Singleton pregnant women who underwent antenatal checkups in the obstetrics department of general hospital affiliated to Ningxia Medical University from July to December 2021 were enrolled in this study to investigate perceived social support, pregnancy-related anxiety and conscious personality traits. Pearson correlation analysis was used to analyze the association between the maternal personality traits, perceived social support, and pregnancy-related anxiety, and the mediating effect of perceived social support was analyzed using Bootstrap method. Results: A total of 1 259 subjects were included in the study, of which 170 (13.50%) pregnant women felt introverted. The total score of perceived social support was (46.37±8.38), and 31.45% of pregnant women had high perceived social support. The total score of pregnancy-related anxiety was (21.48±5.53). The score of worry about fetal health was (10.09±3.24), and 368 (29.23%) of pregnant women had pregnancy-related anxiety. Maternal personality traits and pregnancy-related anxiety were negatively correlated (r=-0.076, P<0.05) and positively correlated with perceived social support during pregnancy (r= 0.127, P<0.05). Perceived social support during pregnancy and pregnancy-related anxiety were negatively correlated (r=-0.236, P<0.05). Perceived social support partially mediated the relationship between the maternal personality traits and pregnancy-related anxiety, with a relative effect value of 37.50%. Conclusion: The maternal personality traits, level of perceived social support and pregnancy-related anxiety are all related. Perceived social support could mediate the relationship between the maternal personality traits and pregnancy-related anxiety.
目的： 探讨领悟社会支持在孕妇性格特征与妊娠相关焦虑之间的中介效应。 方法： 以2021年7至12月在宁夏医科大学总医院产科进行产前检查的单胎孕妇作为研究对象，对其进行领悟社会支持、妊娠相关焦虑及自觉性格特征调查，采用Pearson相关分析对孕妇性格特征、领悟社会支持及妊娠相关焦虑关联性进行分析，采用Bootstrap法对领悟社会支持的中介效应进行分析。 结果： 共纳入研究对象1 259名，其中170名（13.50%）孕妇自觉性格内向；领悟社会支持总得分为（46.37±8.38）分，高领悟社会支持的孕妇占31.45%；妊娠相关焦虑得分总分为（21.48±5.53）分，担心胎儿健康得分为（10.09±3.24）分，368名（29.23%）孕妇有妊娠相关焦虑。孕妇性格特征和妊娠相关焦虑呈负相关（r=-0.076，P<0.05），与孕期领悟社会支持呈正相关（r=0.127，P<0.05）；孕期领悟社会支持和妊娠相关焦虑呈负相关（r=-0.236，P<0.05）；领悟社会支持在孕妇性格特征和妊娠相关焦虑之间起部分中介作用，相对效应值为37.50%。 结论： 孕妇性格特征、领悟社会支持水平和妊娠相关焦虑均相关，领悟社会支持在孕妇性格特征与妊娠相关焦虑关系中起一定的中介效应。.
