Scant research has examined the relationship between posttraumatic
confusion (PTC) and cooperation during rehabilitation from moderate to severe
traumatic brain injury. In this study, PTC and cooperation were examined in a
prospective cohort of 74 inpatients with traumatic brain injury. Confusion was
measured using the Confusion Assessment Protocol. Cooperation was rated on a
0-100 scale by rehabilitation therapists. Using multiple regression analysis, PTC
significantly predicted cooperation (R = 0.33, P < 0.001). Age at injury,
education, days since injury, and Glasgow Come Scale scores were not significant
predictors. Bivariate analyses indicated that four PTC symptoms significantly
predicted poorer cooperation: daytime hypersomnolence (ρ = -0.42, P < 0.001),
agitation (ρ = -0.39, P = 0.001), psychosis (ρ = -0.39, P = 0.001), and cognitive
impairment (ρ = -0.24, P = 0.04). Results provide empirical support that PTC is
associated with poorer cooperation and empirical justification for interventions
to manage confusion during early recovery from traumatic brain injury.
