Suicide is one of the leading causes of death in young people. Therefore, suicide prevention in this age group is a public health priority. There is increasing evidence of the efficacy of suicide prevention programmes, but robust empirical studies are still needed. More precisely, data are needed for school-aged children, brief interventions and distal outcomes such as psychological distress or suicidal thoughts. In addition, to our knowledge, no study has yet scientifically evaluated a brief universal suicide prevention programme in Switzerland. This study investigated the efficacy and acceptability of a brief universal suicide prevention programme for school-aged youths. Primary outcomes included knowledge on suicide, perceived suicide awareness and knowledge of help-seeking resources. Secondary outcomes included acceptability coping skills, suicide-related behaviours and psychological distress.
This non-randomised cluster-controlled trial was conducted in Swiss schools. A 90-minute workshop for universal suicide prevention was delivered to the intervention group (n = 209), and the control group had no intervention (n = 96). Measures were assessed at baseline and after one month. Acceptability was assessed at follow-up in the intervention group only. Data were analysed using three-level mixed effect models with an interaction term between group and time.
There were interaction effects between group and time for most outcomes: perceived suicide awareness (p <0.010), knowledge of help-seeking resources (p <0.001), coping planning (p = 0.039), suicidal ideation (p = 0.019) and psychological distress (p = 0.012). There were no interaction effects on suicide-related knowledge (p = 0.312) and coping for social support (p >0.388). Participants found the workshop enjoyable, not upsetting, and worthwhile.
This study suggested that a brief suicide prevention programme could be beneficial and safe for school-aged youths. This brief programme may contribute to suicide prevention efforts.
自杀是年轻人的主要死因之一。因此，预防这一年龄段的自杀是公共卫生的优先事项。越来越多的证据表明预防自杀计划是有效的，但仍需要强有力的实证研究。更具体地说，需要针对学龄儿童、简短干预和心理困扰或自杀念头等远端结果的数据。此外，据我们所知，瑞士还没有一项研究科学评估过简短的普遍预防自杀计划。本研究调查了针对学龄青年的简短普遍预防自杀计划的效果和可接受性。主要结果包括对自杀的认识、对自杀意识的感知以及对寻求帮助资源的了解。次要结果包括可接受的应对技能、与自杀相关的行为和心理困扰。
本非随机群组对照试验在瑞士学校进行。为干预组（n=209）提供了 90 分钟的普遍预防自杀工作坊，对照组（n=96）没有干预。在基线和一个月后评估了测量结果。仅在干预组评估了随访时的可接受性。使用具有组间和时间交互项的三级混合效应模型分析数据。
大多数结果都存在组间和时间的交互作用：对自杀的感知（p<0.010）、寻求帮助资源的知识（p<0.001）、应对计划（p=0.039）、自杀意念（p=0.019）和心理困扰（p=0.012）。在与自杀相关的知识（p=0.312）和寻求社会支持的应对（p>0.388）方面没有交互作用。参与者认为该工作坊令人愉快、不令人不安且有价值。
本研究表明，简短的预防自杀计划可能对学龄青年有益且安全。该简短计划可能有助于预防自杀。
