To explore factors associated with strain in carers of patients with traumatic brain injury.
Cross-sectional cohort study.
Forty-eight carers of patients with traumatic brain injury admitted to a neurosurgical unit over a 9-year period were assessed an average of 9.3 years after injury.
Caregiver Strain Index (CSI), Neurobehavioral Functioning Inventory (NFI), Glasgow Outcome Scale (GOS), Virginia Prediction Tree Score, and carer and patient demographics.
Carers were assessed via postal survey for levels of strain using the CSI and for their perception of the patients' disabilities using the NFI.
Elevated levels of strain were found in 42% of carers. Using logistic regression, outcome as rated by the patients' general practitioner on the GOS and all subscales of the NFI (except Somatic) explained 41% to 57% of the variance in strain and predicted group membership correctly in 72.9% of cases. No individual variable contributed significantly to the explained variance in the model.
A number of factors appear to combine to result in feelings of strain, but the GOS could be used as a crude screening tool. Interventions for cognitive, behavioral, and emotional difficulties may be most useful for carers.
探讨与创伤性脑损伤患者照顾者压力相关的因素。
横断面队列研究。
48 名创伤性脑损伤患者的照顾者，在神经外科病房接受了 9 年的治疗，在受伤后平均 9.3 年接受了评估。
照顾者压力指数（CSI）、神经行为功能量表（NFI）、格拉斯哥预后量表（GOS）、弗吉尼亚预测树评分以及照顾者和患者的人口统计学数据。
通过邮寄问卷调查照顾者使用 CSI 评估压力水平，使用 NFI 评估他们对患者残疾的感知。
42%的照顾者存在较高水平的压力。使用逻辑回归，患者的全科医生在 GOS 上的评定结果和 NFI 的所有子量表（躯体除外）解释了 41%至 57%的压力差异，并正确预测了 72.9%的患者的分组。没有任何单个变量对模型的解释方差有显著贡献。
似乎有许多因素共同导致了压力感，但 GOS 可以作为一种粗略的筛选工具。针对认知、行为和情感困难的干预措施可能对照顾者最有用。
