OBJECTIVE Suicide rates among African American adolescents have increased exponentially in recent years. The socioecological stressors that can increase suicide risk for African American adolescents, in conjunction with unique suicide risk manifestations within this group, require culturally sensitive preventive interventions. This study examines the efficacy of the Adapted-Coping With Stress course (A-CWS), a culturally tailored preventive intervention, to reduce suicidal ideation in African American adolescents, utilizing a randomized controlled design. METHOD Participants included 410 ninth-grade students in a large Midwestern city; most students identified as Black/African American. Participants were randomly assigned to either the A-CWS intervention or standard care control condition. All participants were assessed at baseline, immediately postintervention, and 6 and 12 months postintervention. RESULTS Treatment effects were examined using latent growth models comparing suicidal ideation trajectories in control and intervention conditions. Analyses were conducted using both intention-to-treat and treatment-as-received samples (i.e., intervention condition participants who attended at least 80% of sessions). In both intention-to-treat and treatment-as-received analyses, there was a significant treatment effect: Individuals in the A-CWS intervention condition with higher baseline ideation evidenced a superior reduction in suicidal ideation over the course of the study, relative to their counterparts in the standard care control condition. CONCLUSION Findings indicate that the A-CWS preventive intervention is efficacious in reducing suicidal ideation among African American adolescents with higher levels of baseline suicidal ideation and that effects sustain over time, with the strongest effect evidenced 12 months postintervention.

减少非裔美国青少年的自杀意念：一项随机对照临床试验。

目标 近年来，非裔美国青少年的自杀率呈指数增长。可能增加非裔美国青少年自杀风险的社会生态压力因素，加上该群体独特的自杀风险表现，需要采取文化敏感的预防干预措施。本研究采用随机对照设计，探讨了适应性应对压力课程 (A-CWS) 的功效，该课程是一种根据文化量身定制的预防性干预措施，旨在减少非裔美国青少年的自杀意念。方法 参与者包括中西部一座大城市的 410 名九年级学生；大多数学生被认为是黑人/非裔美国人。参与者被随机分配到 A-CWS 干预组或标准护理控制组。所有参与者均在基线、干预后立即以及干预后 6 个月和 12 个月进行评估。结果 使用潜在生长模型检查治疗效果，比较对照和干预条件下的自杀意念轨迹。使用意向治疗样本和接受治疗样本（即参加至少 80% 疗程的干预条件参与者）进行分析。在意向治疗和接受治疗分析中，都有显着的治疗效果：在 A-CWS 干预条件下，具有较高基线意念的个体在研究过程中表现出自杀意念的显着减少，相对于他们的同行处于标准护理控制条件下。结论 研究结果表明，A-CWS 预防性干预可有效减少基线自杀意念水平较高的非裔美国青少年的自杀意念，并且效果会随着时间的推移而持续，干预后 12 个月效果最强。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
