Abstract

Introduction

Suicide is a leading cause of death among young people (aged 15–24 years), and as such, identifying targets for early intervention is essential to reducing this risk. Using baseline data from a school-based universal suicide prevention trial, we investigate factors associated with different types of suicidal ideation in secondary school students with implications for youth suicide preventive efforts.

Methods

A self-report questionnaire was administered to students aged 13–16 years (Year 9) before program delivery in four regions across New South Wales, Australia (N = 556). Multinomial logistic regression was used to identify correlates of suicidal ideation type (passive vs. active).

Results

Approximately half the total sample reported recent suicidal ideation (51.6% in the previous two weeks), which included almost one-third reporting active suicidal ideation (32.2% seriously considered suicide or made plans). Participants that were significantly more likely to report active suicidal ideation compared to passive suicidal ideation identified as female (OR = 1.91, 95% CI = 1.02–3.59), Indigenous (OR = 0.21, 95% CI = 0.05–0.80), as sexual minorities (OR = 0.36, 95% CI = 0.13–0.97), and had greater depression severity (OR = 1.11, 95% CI = 1.04–1.19).

Conclusions

Suicidal thoughts are prevalent among young people. Universal and indicated preventive interventions that address depression, as well as bullying and discrimination of minority groups would benefit all young people, particularly those more vulnerable to severe suicidal ideation and suicide attempts.

• Highlights

• Active suicidal ideation (SI) was reported by 32.2% of our student sample aged 13–16 years.

• Active SI is linked to sex (female), Indigeneity status, sexual minority status, and greater depression severity.

• Improved bullying and discrimination policy within schools, and well-being programs targeting depression and promoting help-seeking, would benefit youth.

澳大利亚中学生被动和主动自杀意念和企图的概况：横断面分析

摘要

介绍

自杀是年轻人（15-24 岁）死亡的主要原因，因此，确定早期干预的目标对于降低这种风险至关重要。我们使用以学校为基础的普遍自杀预防试验的基线数据，调查与中学生不同类型的自杀意念相关的因素，以及对青少年自杀预防工作的影响。

方法

在澳大利亚新南威尔士州的四个地区 ( N  = 556)的课程交付前，对 13-16 岁（9 年级）的学生进行了自我报告问卷调查。多项逻辑回归用于确定自杀意念类型（被动与主动）的相关性。

结果

大约一半的样本报告了最近的自杀意念（51.6% 在前两周），其中近三分之一的人报告了积极的自杀意念（32.2% 认真考虑过自杀或制定了计划）。与被确定为女性（OR = 1.91，95% CI = 1.02-3.59）、土著（OR = 0.21，95% CI = 0.05-0.80）、性少数族裔 (OR = 0.36, 95% CI = 0.13–0.97)，抑郁严重程度较高 (OR = 1.11, 95% CI = 1.04–1.19)。

结论

自杀念头在年轻人中很普遍。解决抑郁症以及欺凌和歧视少数群体的普遍和明确的预防干预措施将使所有年轻人受益，尤其是那些更容易产生严重自杀意念和自杀企图的年轻人。

• 强调

• 32.2% 的 13-16 岁学生样本报告了主动自杀意念 (SI)。

• 积极的 SI 与性别（女性）、原住民身份、性少数身份和更严重的抑郁症有关。

• 改进学校内的欺凌和歧视政策，以及针对抑郁症和促进寻求帮助的福利计划，将使青年受益。
