Vocational education is an important part of high school education in China. However, there is little research on high school students' mental health. This study aimed to investigate the prevalence of suicidal behavior (SB) among this population and the mediating role of insomnia, depression, anxiety, and stress in the relationship between Internet addiction (IA) and SB using a structural equation model.
A cross-sectional questionnaire survey was conducted among several vocational high school students in Hunan Province, and 7,968 valid questionnaires were obtained. General demographic data and data from the Dual-Mode Self-Control Scale, Athens Insomnia Scale, Depression Anxiety Stress scale-21, and Revised Chen Internet Addiction Scale were collected. A structural equation model was used to explore the different pathways from IA to SB.
Among the participants, 37.7, 15.7, and 21.8% reported suicidal ideation, plans, and attempts, respectively. The structural equation model confirmed that IA was indirectly related to SB and was mediated by insomnia and/or depression, anxiety, and stress.
First, we only recruited students from vocational schools in Hunan Province, therefore, the sample may not represent the entire population of vocational students in China. Second, self-report scales were used in this study, and clinical diagnosis required professional interviews. Third, since this study had a cross-sectional design, the causal relationship between the variables could not be determined.
The prevalence of SB among vocational high school students in China was significantly high. The prevention of SB related to IA can be attributed to the improvement of insomnia and emotional problems.
职业教育是中国高中教育的重要组成部分。然而，针对高中生心理健康的研究却很少。本研究旨在采用结构方程模型调查该人群自杀行为（SB）的流行情况，以及失眠、抑郁、焦虑和压力在网络成瘾（IA）与 SB 之间关系中的中介作用。
采用横断面问卷调查法对湖南省几所职业高中的学生进行调查，共获得 7968 份有效问卷。收集了一般人口统计学资料以及双模式自我控制量表、雅典失眠量表、抑郁焦虑压力量表-21 和修订版陈网络成瘾量表的数据。采用结构方程模型探讨从 IA 到 SB 的不同途径。
参与者中，分别有 37.7%、15.7%和 21.8%报告有自杀意念、计划和尝试。结构方程模型证实，IA 与 SB 呈间接关系，由失眠和/或抑郁、焦虑和压力介导。
首先，我们仅招募了来自湖南省职业学校的学生，因此，样本可能无法代表中国职业学生的整体人群。其次，本研究使用了自我报告量表，而临床诊断需要专业访谈。第三，由于本研究采用了横断面设计，因此无法确定变量之间的因果关系。
中国职业高中学生 SB 的流行率显著较高。与 IA 相关的 SB 的预防可以归因于失眠和情绪问题的改善。
