To develop cognitive models of financial capacity (FC) in patients with traumatic brain injury (TBI).
Longitudinal design.
Inpatient brain injury rehabilitation unit.
Twenty healthy controls, and 24 adults with moderate-to-severe TBI were assessed at baseline (30 days postinjury) and 6 months postinjury.
The FC instrument (FCI) and a neuropsychological test battery. Univariate correlation and multiple regression procedures were employed to develop cognitive models of FCI performance in the TBI group, at baseline and 6-month time follow-up.
Three cognitive predictor models of FC were developed. At baseline, measures of mental arithmetic/working memory and immediate verbal memory predicted baseline FCI performance (R = 0.72). At 6-month follow-up, measures of executive function and mental arithmetic/working memory predicted 6-month FCI performance (R = 0.79), and a third model found that these 2 measures at baseline predicted 6-month FCI performance (R = 0.71).
Multiple cognitive functions are associated with initial impairment and partial recovery of FC in moderate-to-severe TBI patients. In particular, arithmetic, working memory, and executive function skills appear critical to recovery of FC in TBI. The study results represent an initial step toward developing a neurocognitive model of FC in patients with TBI.
为创伤性脑损伤（TBI）患者建立金融认知能力（FC）的认知模型。
纵向设计。
住院脑损伤康复病房。
20 名健康对照者和 24 名中重度 TBI 成人在基线（损伤后 30 天）和损伤后 6 个月进行评估。
FC 量表（FCI）和神经心理学测试组合。采用单变量相关和多元回归程序，在 TBI 组的基线和 6 个月时间随访中建立 FCI 表现的认知模型。
开发了 3 种 FC 的认知预测模型。在基线时，心算/工作记忆和即时言语记忆的测量值预测了基线 FCI 的表现（R = 0.72）。在 6 个月随访时，执行功能和心算/工作记忆的测量值预测了 6 个月 FCI 的表现（R = 0.79），第三个模型发现，这 2 个测量值在基线时预测了 6 个月 FCI 的表现（R = 0.71）。
多种认知功能与中重度 TBI 患者 FC 的初始损伤和部分恢复有关。特别是，算术、工作记忆和执行功能技能似乎对 TBI 患者 FC 的恢复至关重要。研究结果代表了在 TBI 患者中建立 FC 的神经认知模型的初步步骤。
