Since the 1900s it has been theorized that aggression and suicidality are associated with each other. Research has provided empirical support for such theories, including the specific mechanisms which may explain the association between the two variables. While some researchers have begun examining the specific features of aggression and suicidality that are related to each other, this meta-analysis sought to provide an overall estimate of the association between the two variables among adolescents in order to understand the relationship as a whole. Research reports were retrieved by searching databases (e.g., PsycINFO) and reviewing subsequent reference lists. After reviewing potential research reports, 122 (N = 182623) were selected, and 142 correlations were included in the random-effects meta-analytic model. The average correlation between aggression and suicidality was found to be 0.20, z = 14.53, p < .001, 95% CI [0.17, 0.23], I² = 95.0%, and three moderators were found to significantly influence effect sizes. This meta-analysis demonstrates that there can be a moderate correlation between aggression and suicidality among adolescents, however the average effect size might be smaller or larger depending on methodological features of individual research reports. The observed average correlation may also be a conservative estimate due to the analytic choices for this study. Nonetheless, the results from this study could provide a general sense of the relationship between aggression and suicidality in adolescents.

自1900年代以来，就有理论认为侵略性和自杀性是相互关联的。研究为此类理论提供了经验支持，包括可以解释两个变量之间关联的特定机制。虽然一些研究人员已开始研究彼此相关的侵略性和自杀性的特定特征，但这项荟萃分析旨在对青少年中两个变量之间的关联提供一个整体估计，以便从整体上理解这种关系。通过搜索数据库（例如PsycINFO）并查看后续参考列表来检索研究报告。在审查了潜在的研究报告之后，122（N= 182623），并且在随机效应荟萃分析模型中包含142个相关性。攻击性和自杀性之间的平均相关性为0.20，z = 14.53，p <.001，95％CI [0.17，0.23]，I ²= 95.0％，发现三个主持人对效果大小有显着影响。这项荟萃分析表明，青少年的攻击性和自杀性之间可能存在适度的相关性，但是平均效果大小可能会变小或变大，具体取决于各个研究报告的方法学特征。由于这项研究的分析选择，观察到的平均相关性也可能是保守估计。尽管如此，这项研究的结果仍可以大致了解青少年的攻击性与自杀性之间的关系。
