Abstract

Purpose: Negative life events are essential proximal factors that may induce suicidal behavior in adolescents, but the mechanisms connecting this link remain to further explored. The present study aimed to investigate the relationship between negative life events (NLEs) and adolescents' suicidal behavior, and the roles of core self-evaluation, depression and gender playing between them.

Methods: Using the whole-group sampling approach, 5296 Chinese adolescents (51.5% males, Mean_age = 12.93) took part in this cross-sectional study in September 2021 and completed a battery of surveys including NLEs, suicidal behavior, CSE (core self-evaluation) and depression. Logistic regression and latent structural equation models were used to test the direct and indirect effects between NLEs and suicide behavior with multi-group path analysis, gender differences in this serial mediating effect were also tested.

Results: After controlling for age and gender, NLEs were directly associated with adolescents' suicidal behavior. CSE and depression played significant serial mediating effects in this relationship. Moreover, significant gender differences were obtained in these serial mediating pathways, with stronger effects in girls.

Conclusion: Integrating the environmental, individual cognitive and emotional factors, our findings would be helpful in understanding the mechanism of these antecedents on adolescents' suicide behavior, which has specific practical significance for preventing and reducing suicidal behavior.

青少年负面生活事件与自杀行为之间的关系：核心自我评价、抑郁和性别的作用。

目的：消极生活事件是诱发青少年自杀行为的重要近因，但这一联系的机制仍有待进一步探索。本研究旨在探讨消极生活事件（NLEs）与青少年自杀行为之间的关系，以及核心自我评价、抑郁和性别在两者之间的作用：采用整群抽样方法，于 2021 年 9 月对 5296 名中国青少年（51.5% 为男性，平均年龄 = 12.93）进行了横断面研究，并完成了包括 NLEs、自杀行为、CSE（核心自我评价）和抑郁在内的一系列调查。通过多组路径分析，使用逻辑回归和潜在结构方程模型检验了 NLEs 与自杀行为之间的直接和间接影响，还检验了该序列中介效应的性别差异：结果：在控制了年龄和性别之后，NLEs 与青少年自杀行为直接相关。在这一关系中，CSE 和抑郁具有明显的序列中介效应。此外，在这些序列中介途径中还发现了明显的性别差异，对女孩的影响更大：综合环境因素、个体认知因素和情感因素，我们的研究结果有助于理解这些前因对青少年自杀行为的影响机制，对预防和减少自杀行为具有具体的现实意义。

期刊介绍： Social Psychiatry and Psychiatric Epidemiology is intended to provide a medium for the prompt publication of scientific contributions concerned with all aspects of the epidemiology of psychiatric disorders - social, biological and genetic. In addition, the journal has a particular focus on the effects of social conditions upon behaviour and the relationship between psychiatric disorders and the social environment. Contributions may be of a clinical nature provided they relate to social issues, or they may deal with specialised investigations in the fields of social psychology, sociology, anthropology, epidemiology, health service research, health economies or public mental health. We will publish papers on cross-cultural and trans-cultural themes. We do not publish case studies or small case series. While we will publish studies of reliability and validity of new instruments of interest to our readership, we will not publish articles reporting on the performance of established instruments in translation. Both original work and review articles may be submitted.
