Background:The interdependence between patient and caregivers’ health, which is when the patients’ and informal caregivers’ emotion, cognition and/or behavior affects that of the other person is well documented among dyads experiencing cancer and heart disease, but scant research has assessed interdependence among those with brain injuries or dementia and Latina/o populations. This study aimed to assess the interdependence of patient and caregiver depression, patient functional independence and caregiver burden among non-Latina/o and Latina/o and patients with brain injuries and dementia and their caregivers.Methods:Patients and caregiver dyads (n = 96) were recruited from a trauma hospital. Participants completed measures on patient and caregiver depression, patient functional independence and caregiver burden. Participants provided written informed consent. Patient inclusion criteria included: (1) diagnosis with a brain injury or dementia, (2) minimum age of 12, (3) community dwelling and (4) ability to verbally communicate and complete study measures. Caregivers were only included if they were informal, unpaid, family or a friend. Nonparametric Spearman’s Rho correlations were conducted to test the study hypotheses.Discussion:There was consistently a statistically significant positive relationship between caregiver depression and caregiver burden for all groups. For non-Latina/o patient and caregiver dementia dyads, there were associations between patient depression and caregiver depression. For non-Latina/o dementia dyads, functional ability was only associated with patient depression. For Latina/o patient and caregiver brain injury and dementia dyads, the only statistically significant relationship was between caregiver depression and caregiver burden. Health services should embrace family-focused mental health and respite interventions.

拉丁裔 / o 和非拉丁裔 / o 脑损伤和痴呆症患者和照顾者的健康：演员/合作伙伴相互依赖模型

背景：患者和看护者健康之间的相互依赖关系，即患者和非正式看护者的情绪、认知和/或行为会影响他人的健康，这在患有癌症和心脏病的二元组中有充分的记录，但很少有研究评估过脑损伤或痴呆症患者与拉丁/o 人群之间的相互依存关系。本研究旨在评估非拉丁裔/o 和拉丁裔/o 以及脑损伤和痴呆患者及其护理人员之间患者和护理人员抑郁、患者功能独立性和护理人员负担的相互依赖关系。方法：患者和护理人员二人组（n= 96）是从创伤医院招募的。参与者完成了关于患者和看护者抑郁、患者功能独立性和看护者负担的测量。参与者提供了书面知情同意书。患者纳入标准包括：(1) 诊断为脑损伤或痴呆，(2) 最小年龄为 12 岁，(3) 社区居住和 (4) 口头交流和完成研究措施的能力。只有当他们是非正式的、无偿的、家人或朋友时，他们才会被包括在内。进行了非参数Spearman's Rho 相关性以检验研究假设。讨论：所有组的照顾者抑郁和照顾者负担之间始终存在统计学上显着的正相关关系。对于非拉丁裔/o 患者和看护者痴呆症患者，患者抑郁症和照顾者抑郁症之间存在关联。对于非拉丁裔/o 痴呆二元组，功能能力仅与患者抑郁有关。对于拉丁裔/o 患者和照顾者脑损伤和痴呆二元组，唯一具有统计学意义的关系是照顾者抑郁和照顾者负担之间的关系。卫生服务应包括以家庭为中心的心理健康和临时干预措施。
