摘要
目的 本研究旨在探索睡眠质量和社会支持是否在感知压力与抑郁症状之间起中介或调节作用。方法 本研究于2021年10—12月,对中国中部地区7903名女性居民进行调查。通过自行设计问卷,收集其感知压力、睡眠质量以及社会支持等相关信息,并采用9条目患者健康问卷(PHQ-9)进行抑郁筛查。通过Pearson相关分析研究各变量间相关性,采用结构方程模型(SEM)分析女性居民感知压力、睡眠质量、社会支持、抑郁症状之间的关系。结果 女性居民睡眠质量与感知压力(r=0.300,P <0.001)、社会支持(r=0.306,P <0.001)、抑郁症状(r=0.425,P<0.001)呈显著正相关;社会支持与感知压力(r=-0.197,P<0.001)、抑郁症状(r=-0.432,P<0.001)呈显著负相关;感知压力与抑郁症状(r=0.354,P<0.001)呈显著正相关。睡眠质量在感知压力与抑郁症状之间具有部分中介作用。其中,睡眠质量对抑郁症状的中介效应值为0.102,占总效应的30.82%。此外,社会支持在感知压力与抑郁症状的关系中具有调节作用(β=-0.100,P<0.001)。当社会支持水平较高时,感知压力对抑郁症状的影响较弱。结论 感知压力通过睡眠质量间接影响抑郁症状,社会支持调节了感知压力对抑郁症状的影响。在抑郁症的早期防治中,改善女性居民睡眠质量和提高社会支持是缓解其感知压力对抑郁症状的有效途径。
Objective To explore whether sleep quality mediates the relationship between perceived stress and de-pressive symptoms and whether social support moderates their relationship.Methods A cross-sectional survey was conduc-ted from October 2021 to December 2021 among 7903 female participants in central China.A self-designed questionnaire was used to collect information on participants'perceived stress,sleep quality and social support.Patient Health Question-naire(PHQ-9)was used to measure depressive symptoms.Pearson correlation analysis was conducted to analyze the corre-lations of study variables,and structural equation model(SEM)was used to analyze the relationships among perceived stress,sleep quality,social support and depressive symptoms.Results The results showed that sleep quality was positively correlated with perceived stress(r=0.300,P<0.001),social support(r=0.306,P<0.001)and depressive symp-toms(r=0.425,P<0.001).Social support was negatively correlated with perceived stress(r=-0.197,P<0.001)and depressive symptoms(r=-0.432,P<0.001).Perceived stress was positively correlated with depressive symptoms(r=0.354,P<0.001).Sleep quality partially mediated the association between perceived stress and depressive symp-toms.The mediating effect of sleep quality on depressive symptoms was 0.102,accounting for 30.82%of the total effect.In addition,social support moderated the association between perceived stress and depressive symptoms(β=-0.100,P<0.001).The effect of perceived stress on depressive symptoms was weaker when the level of social support was high-er.Conclusion Perceived stress indirectly affects depressive symptoms through sleep quality,and social support moderates the effect of perceived stress on depressive symptoms.In the early prevention and treatment of depression in women,impro-ving sleep quality and social support are effective ways to alleviate perceived stress and depressive symptoms.
