PURPOSE/OBJECTIVE Traumatic brain injury (TBI) is associated with depression, anxiety, and even suicidality in individuals with TBI and in caregivers. Moreover, emotional functioning in individuals with TBI is linked with caregiver functioning. However, no known studies to date have examined linkages in suicidal ideation in individuals with TBI and family caregivers. This is especially important in Latin America, where TBI rates are high, and where cultural norms influence family caregiving. This study examined associations among self-reported suicidal ideation in individuals with TBI and their primary caregivers over time in Mexico and Colombia. Research Method/Design: A total of 109 individuals and their primary caregivers completed measures during hospitalization for TBI and at 2- and 4-months posthospitalization. The primary outcome was Item 9 from the Spanish version of the Patient Health Questionnaire-9, assessing for thoughts of death or suicide in the previous 2 weeks. RESULTS Patients and caregivers reported high levels of suicidal ideation (18.3%-22.4% and 12.4%-15.7%, respectively) at each time point, and suicidal ideation at one time point strongly predicted ideation at the next. When patients endorsed suicidal ideation in the hospital, their caregivers tended to endorse suicidal ideation 2 months later. Although unaccounted for variables could be driving these relationships, they may also provide possible evidence of causal preponderance between patient and caregiver suicidal ideation post-TBI. CONCLUSIONS/IMPLICATIONS Clinicians and rehabilitation specialists can use these findings to inform suicide risk assessment by expanding these practices to caregivers of patients who endorsed suicidal ideation. Interventions after TBI should incorporate caregivers given this study showed significant interdependence of suicidality between patients and caregivers.

急性创伤性脑损伤后的自杀意念：拉丁美洲患者和护理人员的纵向参与者-伙伴相互依赖模型。

目的/目标 创伤性脑损伤 (TBI) 与 TBI 患者和护理人员的抑郁、焦虑甚至自杀有关。此外，TBI 患者的情绪功能与照顾者功能有关。然而，迄今为止，还没有已知的研究检查 TBI 患者和家庭照顾者的自杀意念之间的联系。这在拉丁美洲尤为重要，那里的脑外伤率很高，文化规范影响家庭护理。本研究调查了墨西哥和哥伦比亚 TBI 患者及其主要照顾者随时间推移自我报告的自杀意念之间的关联。研究方法/设计：共有 109 名个体及其主要照顾者在 TBI 住院期间以及出院后 2 个月和 4 个月完成了测量。主要结果是西班牙版患者健康问卷 9 中的第 9 项，评估过去 2 周内的死亡或自杀念头。结果 患者和看护者在每个时间点报告了高水平的自杀意念（分别为 18.3%-22.4% 和 12.4%-15.7%），并且一个时间点的自杀意念强烈预测下一个时间点的自杀意念。当患者在医院认可自杀意念时，他们的照顾者往往会在 2 个月后认可自杀意念。尽管下落不明的变量可能会推动这些关系，但它们也可能提供 TBI 后患者和护理人员自杀意念之间因果优势的可能证据。结论/意义 临床医生和康复专家可以利用这些发现为自杀风险评估提供信息，方法是将这些实践扩展到支持有自杀意念的患者的护理人员。TBI 后的干预措施应纳入照顾者，因为这项研究表明患者和照顾者之间的自杀倾向存在显着的相互依赖性。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
