ImportanceBecause of increased suicide rates among Black youth in the past 2 decades, there is a dire need for research on suicidal ideation and risk factors in this population.ObjectiveTo examine the direct and indirect associations between online racial discrimination and suicidal ideation through posttraumatic stress disorder symptoms among Black adolescents living in the US, with consideration of potential differential associations by gender and age.Design, Setting, and ParticipantsThis cross-sectional study used data drawn from the first wave of the National Survey of Critical Digital Literacy. Black adolescents aged 11 to 19 years were selected from a nationally representative probability-based sample. Data were collected from October 2020 to December 2020 and analyzed from August 2021 to October 2021.Main Outcomes and MeasuresHypotheses of the current study were formulated during research design and grounded in empirical literature. The individual online racial discrimination subscale (Online Victimization Scale), the UCLA Child/Adolescent posttraumatic stress disorder Reaction Index for DSM-5, and an item from the second edition of the Children’s Depression Inventory were used to assess constructs. Mediation was assessed through mediation models with path analyses using structural equation modeling.ResultsAmong a total 525 participants, 265 were girls (50.5%) and 251 were boys (47.8%); the mean (SD) age was 14.8 (2.5) years. Findings from structural equation modeling analysis indicated that individual online racial discrimination was associated with posttraumatic stress disorder symptoms (β = 0.49, SE = 0.06, P < .001), and posttraumatic stress disorder symptoms were associated with suicidal ideation (β = 0.51, SE = 0.06, P < .001). Posttraumatic stress disorder was identified as a full mediator between online racial discrimination and suicide (β = 0.25, SE = 0.04, P < .001). No differences by gender or age were found. Furthermore, no significant direct association between online racial discrimination and suicidal ideation was found.Conclusions and RelevanceThis study found an association between individual online racial discrimination and posttraumatic stress disorder symptoms and between posttraumatic stress disorder symptoms and suicidal ideation. These risk factors are important to consider in continuing studies of the cause of suicidal ideation for Black adolescents in the US.

全国黑人青少年样本中的网络种族歧视、自杀意念和创伤性压力

重要性由于过去20年黑人青年的自杀率不断上升，因此迫切需要对这一人群的自杀意念和危险因素进行研究。目的通过创伤后应激障碍症状研究网络种族歧视与自杀意念之间的直接和间接关联设计、设置和参与者这项横断面研究使用了来自第一波全国关键数字素养调查的数据。11 至 19 岁的黑人青少年是从具有全国代表性的概率样本中选出的。收集了2020年10月至2020年12月的数据，并分析了2021年8月至2021年10月的数据。主要结果和措施本研究的假设是在研究设计期间制定的，并以实证文献为基础。个人在线种族歧视量表（在线受害量表）、加州大学洛杉矶分校儿童/青少年创伤后应激障碍反应指数帝斯曼-5，以及第二版儿童抑郁量表中的一个项目用于评估结构。通过中介模型和使用结构方程模型进行路径分析来评估中介作用。结果在总共 525 名参与者中，女孩 265 名（50.5%），男孩 251 名（47.8%）；平均 (SD) 年龄为 14.8 (2.5) 岁。结构方程模型分析结果表明，个人网络种族歧视与创伤后应激障碍症状相关（β = 0.49，SE = 0.06，磷< .001），创伤后应激障碍症状与自杀意念相关（β = 0.51，SE = 0.06，磷< .001）。创伤后应激障碍被认为是网络种族歧视和自杀之间的完全中介因素（β = 0.25，SE = 0.04，磷< .001）。没有发现性别或年龄方面的差异。此外，没有发现网络种族歧视与自杀意念之间存在显着的直接关联。结论和相关性本研究发现个人网络种族歧视与创伤后应激障碍症状之间以及创伤后应激障碍症状与自杀意念之间存在关联。在继续研究美国黑人青少年自杀意念的原因时，考虑这些风险因素非常重要。
