目的:通过积极反刍思维训练的团体辅导干预实验，改善大学生的抑郁情绪，并验证自我效能在其中的中介作用。方法:研究对象为抑郁程度轻中度的大学生，随机分为干预组(积极反刍思维训练)、积极对照组(传统认知行为疗法)和对照组(无干预)。使用抑郁自评、一般自我效能感、积极反刍思维和消极反刍思维量表进行评估。结果:本研究通过对干预组、积极对照组和对照组进行为期8周的积极反刍训练团辅干预，结果显示，干预前，3组在年龄、积极反刍、消极反刍、自我效能及抑郁得分上差异无统计学意义，具备良好的同质性。干预后，干预组在消极反刍思维及其消极归因、自我否定因子得分上显著下降(t=3.67,2.17,Z=-2.70;P<0.05),享受快乐因子与自我效能感得分显著提升(Z=-2.20,-2.10;P<0.05),差异有统计学意义；而积极对照组与对照组在各项指标上均未出现显著变化。进一步的中介效应分析表明，自我效能在积极反刍与抑郁、消极反刍与抑郁之间均起部分中介作用，中介效应显著，效应值分别是-0.419,0.354;说明自我效能是反刍思维影响抑郁的重要中介机制。结论:积极反刍思维团体辅导能有效改善其反刍思维、提升自我效能并缓解抑郁情绪，且自我效能在其中起关键的中介作用，为大学生心理健康干预提供了新途径，建议将其纳入心理健康课程，并在未来的研究中进行长期追踪和多中心随机对照试验。

Objective:To improve college students'depressive symptoms and verify the mediating role of self-efficacy through a group counseling intervention experiment using active rumination thinking training.Methods:Participants with mild to moderate depression were randomly assigned to three groups: An active rumination thinking training group, an active control group(traditional cognitive behavioral therapy),and a control group(no intervention).Assessments were conducted using the Depression Self-Rating Scale, General Self-Efficacy Scale, and Rumination Scale.Results:This study conducted an 8-week active rumination training group intervention on the intervention group, active control group, and control group.The results showed that before the intervention, there were no significant differences(P>0.05)in age, active rumination, negative rumination, self-efficacy, and depression scores among the three groups, indicating good homogeneity.After intervention, the intervention group showed a significant decrease in scores for negative rumination, negative attribution, and self denial factors(t=3.67,2.17,Z=-2.70,P<0.05),while scores for enjoyment of pleasure and self-efficacy were significantly improved(Z=-2.20,-2.10;P<0.05).Depression scores also decreased; However, there were no significant changes in various indicators between the active control group and the control group.Further mediation analysis showed that self-efficacy partially mediated the relationship between positive rumination and depression,as well as negative rumination and depression,with significant mediation effects and effect values of-0.419and 0.354,respectively;Self efficacy was an important mediating mechanism by which rumination affects depression.Conclusion:Positive rumination group counseling effectively improves rumination,enhances self-efficacy,and alleviates depressive symptoms,with self-efficacy playing a key mediating role.This provides a novel approach for mental health interventions for college students.It is recommended to incorporate this method into mental health curricula and conduct long-term follow-up and multicenter randomized controlled trials in future research.
