Suicide is a serious global public health problem, and suicidal ideation is a significant predictor of and risk factor for suicide deaths. Previous studies have confirmed the relationships among suicidal ideation, the meaning of life and coping styles using latent variables but have overlooked the heterogeneity of symptoms.
The purpose of this study was to explore the fine-grained relationships among these three factors based on network analysis to provide a theoretical basis to identify potential psychological interventions for suicidal ideation.
These factors were investigated by administering the Chinese Meaning of life Questionnaire (C-MLQ), the Simple Coping Styles Questionnaire (SCSQ), and the Suicidal Ideation Self-Assessment Scale (SIOSS) to 800 self-reported healthy adults. Analyses of network structure and bridge expected influence (BEI) were conducted with R4.1.1 software.
The network showed a total of 18 edges for the meaning of life, coping styles, and suicidal ideation communities. Of these, S1, "pessimism", had the greatest negative BEI value (-0.25) in the suicidal ideation community; M1, "perception of meaning of life", had the greatest negative BEI value (-0.42) in the meaning of life and coping styles communities; and C2, "negative coping", had the greatest positive BEI value (0.31).
Complex pathways exist among meaning of life, coping styles and suicidal ideation. Negative coping is the strongest risk factor for suicidal ideation, the perception of the meaning of life is the strongest protective factor for suicidal ideation, and pessimism is a potential target for suicide prevention interventions.
自杀是一个严重的全球公共卫生问题，自杀意念是自杀死亡的重要预测指标和风险因素。以往的研究已经通过潜在变量证实了自杀意念、生命意义和应对方式之间的关系，但忽略了症状的异质性。
本研究旨在基于网络分析探讨这三个因素之间的细粒度关系，为识别自杀意念的潜在心理干预措施提供理论依据。
通过对800名自我报告的健康成年人进行中国生命意义问卷（C-MLQ）、简易应对方式问卷（SCSQ）和自杀意念自评量表（SIOSS）来调查这些因素。使用R4.1.1软件进行网络结构分析和桥接预期影响（BEI）分析。
该网络显示生命意义、应对方式和自杀意念群落共有18条边。其中，S1“悲观主义”在自杀意念群落中的负BEI值最大（-0.25）；M1“生命意义感知”在生命意义和应对方式群落中的负BEI值最大（-0.42）；C2“消极应对”的正BEI值最大（0.31）。
生命意义、应对方式和自杀意念之间存在复杂的路径。消极应对是自杀意念最强的风险因素，生命意义感知是自杀意念最强的保护因素，悲观主义是自杀预防干预的潜在目标。
