功能失调性睡眠认知与孕妇失眠症状的关系:睡眠安全行为的中介与社会支持的调节作用

Relationship between dysfunctional sleep cognition and insomnia symptoms in pregnant women:The mediating role of sleep-related safety behaviors and the moderating role of social support

目的:探讨功能失调性睡眠认知与孕妇失眠症状的关系及其中介、调节变量。方法:采用简式功能失调性睡眠信念与态度量表、失眠严重程度量表、睡眠相关行为量表、领悟社会支持量表对455名健康孕妇进行调查。结果:功能失调性睡眠认知显著负向预测睡眠安全行为(B=-0.361,P<0.001),睡眠安全行为正向预测失眠症状(B=0.455,P<0.001);睡眠安全行为在功能性失调睡眠认知与失眠症状之间起到中介作用;社会支持显著负向调节睡眠安全行为与失眠症状之间的关系。结论:功能失调性睡眠认知会增加睡眠安全行为的使用频率,进而加重个体的失眠症状;高社会支持可以缓和睡眠安全行为对失眠症状的影响。

Objective:To investigate the relationship between dysfunctional sleep cognition and insomnia symptoms in pregnant women,as well as its mediating and regulating variables.Methods:A total of 455 healthy pregnant women were investigated by Dysfunctional Beliefs and Attitudes about Sleep Scale-16 item(DBAS-16),Insomnia Severity Index(ISI),Sleep-related Behaviours Questionnaire(SRBQ)and Perceived Social Support Scale(PSSS).Results:Dysfunctional sleep cognition negatively predicted sleep-related safety behaviors(B=-0.361,P<0.001),and sleep-related safety behaviors positively predicted insomnia symptoms(B=0.455,P<0.001).Sleep-relate safety behaviors mediated between dysfunctional sleep cognition and insomnia symptoms.Social support significantly negatively moderated the relationship between sleep-related safety behaviors and insomnia symptoms.Conclusion:Dysfunctional sleep cognition can increase the frequency of sleep-related safety behaviors,and further aggravate the insomnia symptoms of individuals.High social support mitigated the effects of sleep-related safety behaviors on insomnia symptoms.
