家庭功能缺失对在校大学生轻生行为的影响机制及干预对策研究

The Influence Mechanism of Family Dysfunction on Suicidal Behavior among College Students and Intervention Strategies

摘要: 家庭功能缺失是大学生自杀行为的重要风险因素。本研究基于某高校398名学生的问卷调查，发现情感支持缺失(78.48%)、家庭冲突或暴力(72.15%)及不合理期望(68.99%)是三大核心诱因。结合Joiner的人际心理自杀理论(IPTS)，研究构建了“情感–认知–行为”交互作用模型，并据此提出包含高校三级预防体系与家校协同干预方案的综合性策略，为降低大学生自杀风险提供实证依据和干预路径。

Abstract: Family dysfunction is a critical risk factor for suicidal behavior among college students. Based on a questionnaire survey of 398 students from a university, this study identifies three core triggers: emotional support deprivation (78.48%), family conflict or violence (72.15%), and unreasonable expectations (68.99%). Integrating Joiner’s Interpersonal-Psychological Theory of Suicide (IPTS), the research constructs an “emotion-cognition-behavior” interactive model. Building on this framework, a comprehensive strategy is proposed, including a university-level three-tier prevention system and a school-family collaborative intervention framework, to provide empirical evidence and actionable pathways for mitigating suicidal risks in college students.
