揭示消极反刍思维是改善抑郁大学生执行功能损害的核心靶点:基于双重反刍思维模型的中介分析OA
Revealing negative rumination as a core target for improving executive function impairment in depressed college students:A mediation analysis based on the dual rumination model
目的 探讨积极和消极反刍思维在大学生抑郁症状与执行功能及其子成分(抑制控制、工作记忆、认知灵活性)关系中的中介作用.方法 于2024年9-10月期间,采用方便抽样法,通过问卷星平台向重庆、四川等全国30个省(市)高校发放电子问卷.采用患者健康问卷抑郁量表(patient health questionnaire-9,PHQ-9)、积极和消极反刍思维量表(positive and negative rumination scale,PANRS)及执行功能行为评定量表成人版(behavior rating inventory of executive function-adult version,BRIEF-A)对699名大学生进行线上调查,依据PHQ-9评分标准将大学生划分为抑郁症状组(n=466,66.67%)和非抑郁症状组(n=233,33.33%).比较2组大学生在各量表得分上的差异,并分析各变量间的关系及中介效应.结果 ①抑郁症状组消极反刍思维得分显著高于非抑郁症状组[(30.27±4.93)vs(26.42±3.81),t=-10.451,P<0.001],执行功能及其子成分、积极反刍思维得分显著低于非抑郁症状组(P<0.001);②抑郁症状与消极反刍思维呈显著正相关(r=0.394,P<0.01),与执行功能及其子成分呈显著负相关(P<0.01),与积极反刍思维无显著关联(P>0.05).③消极反刍思维在大学生抑郁症状与执行功能关系中起到中介作用,中介效应占比为10.85%,积极反刍思维正向预测执行功能(β=0.086,P<0.05).④消极反刍思维在大学生抑郁症状与执行功能子成分关系中的中介作用具有特异性(仅对抑制控制和工作记忆显著,间接效应占比分别为8.11%和16.94%);积极反刍思维未表现出显著的中介作用.结论 消极反刍思维在大学生抑郁症状与执行功能(尤其是抑制控制和工作记忆)之间起部分中介作用,是改善抑郁大学生执行功能受损的核心干预靶点.
Objective To explore the mediating roles of positive and negative rumination in the relationship between depressive symptoms and executive function and its subdomains(inhibitory control,working memory,and cognitive flexibility)among college students.Methods During September and October 2024,an electronic questionnaire was distributed using convenience sampling through the"Wenjuanxing"platform to universities in 30 provinces and municipalities across China,such as Chongqing and Sichuan.A total of 699 college students were surveyed online using patient health questionnaire-9(PHQ-9),positive and negative rumination scale(PANRS),and behavior rating inventory of executive function-adult version(BRIEF-A).The participants were divided into depressive symptom group(n=466,66.67%)and a non-depressive symptom group(n=233,33.33%)based on PHQ-9 score.Differences in scores between the 2 groups were compared,and the relationships between variables as well as the mediating effects were analyzed.Results ① Scores of negative rumination were significantly higher in the depressive symptom group than in the non-depressive symptom group[(30.27±4.93)vs(26.42±3.81),t=-10.451,P<0.001],while executive function and its subdomains,as well as positive rumination,were significantly lower(r=0.394,P<0.01).② Depressive symptoms showed a significant positive correlation with negative rumination and a significant negative correlation with executive function and its subdomains(P<0.01),but no significant correlation with positive rumination(P>0.05).③ Negative rumination exhibited a mediating effect in the relationship between depressive symptoms and executive function,accounting for 10.85%of the total effect,whereas positive rumination served as a positive predictor of executive function(β=0.086,P<0.05).④ The mediating effect of negative rumination between depressive symptoms and executive function subdomains demonstrated domain specificity,reaching statistical significance only for inhibitory control and working memory,with indirect effect ratios of 8.11%and 16.94%respectively,but not for cognitive flexibility.No significant mediating effect was observed for positive rumination.Conclusion Negative rumination plays a partial mediating role between depressive symptoms and executive function(particularly in inhibitory control and working memory)among college students,and it can be regarded as a core modifiable target for interventions to improve executive dysfunction in depressed college students.
