We systematically reviewed (evaluated methodological quality) meta-analysis studies on the suicidal ideation of South Koreans using a measurement tool to assess systematic reviews version 2 (AMSTAR-2) to present the ways for improving the quality of follow-up meta-analysis studies and suggest the direction of future studies.
We analyzed 11 meta-analysis studies based on AMSTAR-2 criteria by collecting documents related to suicidal thoughts using seven electronic databases (DBPia, Scholar, KISS, KCI, RISS, KoreaEmbase, and National Assembly Electronic Library) from Jan 1, 2000 to Dec 3, 2022.
Among the 142 papers searched, we analyzed the final 11 selected studies. Not all analyzed meta-analysis studies conducted quality assessment and these studies omitted the list of excluded references and the adequacy of the literature search. Moreover, 54.5% of the analyzed studies (six out of eleven studies) did not present the effect of publication bias. Consequently, SOMETHING was critically low due to omissions in critical domains.
In all 11 studies analyzed, 2 or more of 7 critical domains were omitted, and the quality level was confirmed to be critically low. Therefore, future meta-analysis studies on suicidal ideation will have to include quality assessment and improve the quality of meta-analysis, such as testing bias effects.
我们使用系统评价的测量工具评估系统评价第2版（AMSTAR-2），对关于韩国人自杀意念的荟萃分析研究进行了系统评价（评估方法学质量），以呈现提高后续荟萃分析研究质量的方法，并为未来研究指明方向。
我们通过使用七个电子数据库（DBPia、Scholar、KISS、KCI、RISS、KoreaEmbase和国民议会电子图书馆）收集与自杀想法相关的文献，根据AMSTAR-2标准分析了11项荟萃分析研究，时间跨度为2000年1月1日至2022年12月3日。
在检索到的142篇论文中，我们分析了最终选定的11项研究。并非所有分析的荟萃分析研究都进行了质量评估，这些研究遗漏了排除参考文献列表和文献检索的充分性。此外，54.5%的分析研究（11项研究中的6项）未呈现发表偏倚的影响。因此，由于关键领域的遗漏，某些方面非常低。
在所有分析的11项研究中，7个关键领域中有2个或更多被遗漏，质量水平被证实非常低。因此，未来关于自杀意念的荟萃分析研究必须包括质量评估，并提高荟萃分析的质量，如检验偏倚效应。
