认知情绪调节在大学生生活事件与自杀意念关系的中介效应

Mediation effect of cognitive emotion regulation on relationship between life events and suicide idea-tion among college students

目的：考察认知情绪调节的积极策略和消极策略在生活事件与大学生自杀意念关系的中介效应，以及社会支持在该中介模型中的调节效应。方法采用青少年生活事件量表、认知情绪调节问卷、大学生社会支持评定量表和大学生自杀意念自评量表对湖南省某高校2471名大学生进行调查，建立有调节的中介模型。结果认知情绪调节的消极策略在生活事件与自杀意念之间中介作用显著（β＝0．17， t＝8．43， P＜0．01），中介效应等于0．28×（0．18－0．05U），社会支持（U）在这一中介过程的后半路径调节作用显著（β＝－0．05， t＝－2．47， P＜0．05），当U变化一个单位时，中介效应变化0．05个单位。结论生活事件通过消极策略间接影响大学生自杀意念，而消极策略对自杀意念的影响随着社会支持水平的增高而减少。

Objective To investigate the mediating effect of the positive and the negative strategy of cognitive emotion regulation on the relationship between life events and suicide ideation among college students,as well as the moderating effect of social support on the mediation model.Methods Participants were 2 471 college students in Hunan province,and they completed the Adolescent Self-rating Life Events Check List,the Cognitive Emotion Regulation Questionnaire, the Social Support Scale for university students and the Suicide Ideation Questionnaire for university students .Results Negative strategy of cognitive emo-tion regulation played a mediating role between life events and suicide ideation among college students （β=0.17, t=8.43, P〈0.01）.Mediating effect quoted 0.28×（0.18-0.05U）.Social Support （U） played a moder-ating role on the second path of mediation （β=-0.05, t=-2.47, P〈0.05） .When U changed one unit,medi-ating effect changed 0.05 unit.Conclusion Life events influence suicide ideation through negative strategy, and with social support increasing,the effect of negative strategy on suicidal ideation weakened.
