Objective: To assess the effectiveness of middle and high school-based suicide prevention curricula.
Data sources: 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.
Review methods: 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.
Results: 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.
Conclusion: 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.
