OBJECTIVE: : To develop cognitive models of financial capacity (FC) in patients
with traumatic brain injury (TBI).
DESIGN: : Longitudinal design.
SETTING: : Inpatient brain injury rehabilitation unit.
PARTICIPANTS: : Twenty healthy controls, and 24 adults with moderate-to-severe
TBI were assessed at baseline (30 days postinjury) and 6 months postinjury.
MAIN OUTCOME MEASURES: : 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.
RESULTS: : 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).
CONCLUSIONS: : 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.
