Suicide, the second leading cause of death among adolescents, requires an integrative approach to maximize the effectiveness of prevention efforts. The current study draws on the social-ecological model and its relevance to the ecosystem at Vocational Education and Training (VET) high schools in the context of suicide prevention. The study examined the school-related factors of school connectedness, academic self-efficacy and school autonomy support in relation to suicidal thoughts and behavior. Participants included 5688 students (mean age 15.58) drawn from 62 vocational high schools across Israel. Structural equation modeling revealed that school connectedness and academic self-efficacy exhibit negative links to suicide ideation and behavior; moreover, these links were partly mediated by depressive symptoms. School autonomy support was found to be positively linked to suicide ideation and suicide attempts. The paper discusses the results with respect to suicide prevention efforts in the unique context of adolescents attending vocational schools.

自杀是青少年中第二大死亡原因，因此需要采取综合措施来最大程度地发挥预防作用的有效性。本研究借鉴了自杀预防背景下的社会生态模型及其与职业教育和培训（VET）高中生态系统的相关性。这项研究检查了与学校相关的因素，包括与自杀念头和行为有关的学校联系性，学业自我效能感和学校自治支持。参加者包括来自以色列62所职业中学的5688名学生（平均年龄15.58）。结构方程模型表明，学校联系和学业自我效能感与自杀观念和行为呈负相关。而且，这些联系部分地由抑郁症状介导。发现学校自治支持与自杀观念和自杀企图有正向联系。本文讨论了在就读职业学校的青少年中自杀预防工作的结果。
