孕期生活事件与抑郁:认知情绪调节策略的中介作用及神经质人格的调节作用

目的探讨孕期生活事件、认知情绪调节策略、神经质人格与孕妇抑郁之间的关系及内在作用机制。方法使用短期纵向追踪设计,在T1时间点采用孕妇生活事件量表、认知情绪调节策略问卷以及中国大五人格问卷简式版神经质分量表对327名妊娠晚期孕妇进行问卷调查,间隔6周后在T2时间点采用患者健康问卷9进行追踪调查,使用SPSS 20.0的宏程序PROCESS检验认知情绪的中介效应和神经质的调节效应。结果(1)以患者健康问卷9总分7分作为临界值,妊娠晚期抑郁的发生率12.23%。(2)孕妇生活事件总分(T1)与非适应认知情绪调节策略总分(T1)呈显著正相关(r=0.25,P<0.01),神经质人格总分(T1)与抑郁情绪总分(T2)呈显著正相关(r=0.46,P<0.01)、孕妇生活事件总分(T1)与抑郁情绪总分(T2)呈显著正相关(r=0.36,P<0.01)。(3)非适应性认知情绪调节策略(T1)在生活事件(T1)与抑郁(T2)间起着部分中介作用,该直接效应(效应值=0.29)和中介效应(效应值=0.07)分别占总效应(效应值=0.36)的80.55%,19.44%;(4)神经质人格调节该中介模型的中介效应后半段,具体而言,个体的神经质人格水平越高,非适应认知情绪调节策略对孕妇抑郁的正向预测作用越强。结论孕期生活事件通过非适应认知情绪调节策略的中介作用以及神经质的调节作用对孕妇抑郁情绪起作用。

The effect of life events during pregnancy on depression:the mediating role of cognitive emotional regulation strategies and the moderating role of neuroticism

Objective To investigate the relationship between life events,cognitive emotional regulation strategies,neuroticism and depression in pregnant women and the internal mechanism of action.Methods Short-term longitudinal follow-up design were used in this study.A total of 327 pregnant women in the third trimester of pregnancy were investigated with pregnant women's life events scale,cognitive emotion regulation strategy questionnaire,neuroticism subscale of Chinese big five personality questionaire-short form at T1 time point,and patient health questionnaire 9 were measured after 6 weeks(T2).SPSS 20.0 macro program PROCESS was used to examine the mediating effect of cognitive emotion and the moderating effect of neuroticism.Results(1)The incidence of depression in the third trimester pregnant women was 12.23%.(2)There was significant positive correlation between the total score of life events in pregnant women(T1)and the total score of non-adaptive cognitive emotional regulation strategies(T1)(r=0.25,P<0.01).Total neurotic personality(T1)and total depressive mood(T2)were significantly positively correlated(r=0.46,P<0.01).The total scores of life events(T1)of pregnant women were significantly positively correlated with the total scores of depression(T2)(r=0.36,P<0.01).(3)The non-adaptive cognitive emotion regulation strategy(T1)played a partial mediating role between life events(T1)and depression(T2).The direct effect(effect size=0.29)and the mediating effect(effect size=0.07)accounted for 80.55%and 19.44%of the total effect(effect size=0.36).(4)Neuroticism regulates the second part of the mediating effect of the mediating model.Specifically,the higher the level of individual neuroticism,the stronger the positive predictive effect of non-adaptive cognitive emotion regulation strategies on maternal depression.Conclusion Pregnant life events play a role in maternal depression through the mediating role of non-adaptive cognitive emotional regulation strategies and the moderating role of neuroticism.
