Various studies have suggested that perseverative cognitions play an important role in the occurrence of suicide. However, the mediating mechanisms underlying the relationship between perseverative cognitions and suicidality remain largely unknown. Accordingly, the present study aimed to investigate whether positive and negative valence systems and social disconnection temporally mediated the association between perseverative cognitions and suicidal behaviors. 256 university students participated in this study. The data were collected using the Perseverative Cognitions Questionnaire (PCQ), Approach-Avoidance Temperament Questionnaire (ATQ), Social Connectedness Scale-Revised (SCS-R), and Suicidal Behaviors Questionnaire-Revised (SBQ-R). The results showed that perseverative cognitions had a direct and significant effect on suicide (p <.001). Positive and negative valence systems and social disconnection significantly mediated the relationship between perseverative cognitions and suicide. Our findings showed that multiple factors including perseverative cognitions, positive and negative valence systems, and social disconnection may have a role in the occurrence of suicide among university students.
多项研究表明，执着性认知在自杀的发生中起着重要作用。然而，执着性认知与自杀倾向之间关系的中介机制在很大程度上仍不为人知。因此，本研究旨在调查正性和负性价系统以及社会脱节是否在执着性认知与自杀行为之间的关联中起到时间中介作用。256名大学生参与了本研究。使用执着性认知问卷（PCQ）、趋避气质问卷（ATQ）、修订版社会联结量表（SCS-R）和修订版自杀行为问卷（SBQ-R）收集数据。结果表明，执着性认知对自杀有直接且显著的影响（p <.001）。正性和负性价系统以及社会脱节显著中介了执着性认知与自杀之间的关系。我们的研究结果表明，包括执着性认知、正性和负性价系统以及社会脱节在内的多种因素可能在大学生自杀的发生中起作用。
