To assess the effectiveness of middle and high school-based suicide prevention curricula.
The following were searched: Ovid MEDLINE(R) in-process and other non-indexed citations and Ovid MEDLINE(R), Ovid Healthstar, CINAHL, PsycINFO, all EBM reviews-Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED, and the ISI Web of Science, until October 2009; government web pages for statistics and other demographic data in countries where they were available; citation lists of relevant articles.
Randomised controlled studies, interrupted time series analyses with a concurrent comparison group, studies with follow-up examinations (post-test questionnaires and monitoring suicide rates), and middle to high school-based curriculum studies, including both male and female participants, were included.
36 potentially relevant studies were identified, eight of which met the inclusion criteria. Overall, statistically significant improvements were noted in knowledge, attitude, and help-seeking behaviour. A decrease in self reported ideation was reported in two studies. None reported on suicide rates.
Although evidence exists that school-based programmes to prevent suicide among adolescents improve knowledge, attitudes, and help-seeking behaviours, no evidence yet exists that these prevention programmes reduce suicide rates. Further well designed, controlled research is required before such programmes are instituted broadly to populations at risk.
评估中学和高中自杀预防课程的效果。
检索了以下数据库：Ovid MEDLINE（R）正在处理的和其他非索引引用以及 Ovid MEDLINE（R）、Ovid Healthstar、CINAHL、PsycINFO、所有循证医学评价- Cochrane DSR、ACP 杂志俱乐部、DARE、CCTR、CMR、HTA 和 NHSEED，以及 ISI Web of Science，截至 2009 年 10 月；有统计数据和其他人口数据的国家的政府网页；相关文章的参考文献列表。
纳入随机对照研究、具有同期对照的时间序列分析研究、有随访检查（后测问卷和监测自杀率）的研究以及基于中学和高中的课程研究，包括男性和女性参与者。
确定了 36 项潜在相关研究，其中 8 项符合纳入标准。总体而言，知识、态度和寻求帮助行为均有统计学意义上的显著改善。两项研究报告了自我报告意念的减少。没有研究报告自杀率。
虽然有证据表明，针对青少年的学校自杀预防计划可以提高知识、态度和寻求帮助行为，但尚无证据表明这些预防计划可以降低自杀率。在向高危人群广泛实施这些计划之前，需要进行进一步的精心设计和对照研究。
