Suicide is the second leading cause of death among adolescents in the U.S., and emerging evidence indicates that gang-involved youth may be at elevated risk. Yet, little is known about suicidality prevalence among subgroups of gang and non-gang youth due to limited measures of social identity in previous studies. Guided by an intersectional framework, this study examined gang and non-gang differences in suicidality across an array of social identities and tested the effect of gang membership on suicidality within the context of cumulative marginalization. Data come from a statewide, school-based sample of adolescents in the 8th, 10th, and 12th grades (N = 81,080). Chi-square and independent samples t-tests examined group differences in rates of self-reported suicidal ideation, planning, and attempts. Logistic regression models tested the moderating effect of multiple marginalized identities on the gang-suicidality link. Gang-involved youth reported significantly higher suicidality compared to non-gang youth, with between-group disparities observed across singular marginalized identities. However, moderation analyses found that the effect of gang membership on suicidal ideation and planning was less salient in the context of cumulative marginalization. Findings suggest that gang-involved youth represent a unique and diverse population at risk of suicide. At the same time, gang membership may also offer some degree of protection against early stages of suicide for those with a greater number of marginalized identities. Implications for social work science and practice within an intersectional framework are discussed.

自杀是美国青少年的第二大死因，新出现的证据表明参与帮派的青少年面临更高的风险。然而，由于先前研究中社会认同的测量有限，我们对帮派和非帮派青年亚群的自杀流行率知之甚少。在交叉框架的指导下，本研究调查了一系列社会身份中帮派和非帮派在自杀方面的差异，并测试了在累积边缘化的背景下帮派成员身份对自杀的影响。数据来自全州范围内以学校为基础的 8 年级、10 年级和 12 年级青少年样本（N  = 81,080）。卡方和独立样本t-测试检查了自我报告的自杀意念、计划和尝试率的组别差异。逻辑回归模型测试了多重边缘化身份对帮派-自杀联系的调节作用。与非帮派青年相比，参与帮派的青年自杀率明显更高，在单一的边缘化身份中观察到群体间差异。然而，调节分析发现，在累积边缘化的背景下，帮派成员身份对自杀意念和计划的影响不太显着。调查结果表明，参与帮派的青年代表了一个独特而多样化的自杀风险人群。与此同时，帮派成员身份也可能为那些边缘化身份较多的人提供一定程度的保护，使其免于早期自杀。
