OBJECTIVE: To determine factors related to three-month follow-up outcomes for
individuals participating in an outpatient rehabilitative treatment program for
mild traumatic brain injury (TBI).
METHOD: Fifty participants underwent neuropsychological screening prior to
treatment initiation and completed the Mayo-Portland Adaptability Inventory-4
(MPAI-4) at treatment initiation, discharge from treatment, and three months
RESULTS: Regression models indicated that information garnered from the
neuropsychological screening prior to treatment initiation (e.g., mood symptoms
and prior psychiatric history) accounted for unique variance in three-month
post-discharge outcomes on several MPAI-4 subscales. Specifically, after
controlling for baseline MPAI-4 ratings, higher Beck Depression Inventory-second
edition (BDI-II) scores were associated with worse MPAI-4 Ability scores at
three-month follow-up, and the presence of a psychiatric history was associated
with worse MPAI-4 Adjustment scores at three-month follow-up.
CONCLUSIONS: Neuropsychological screening prior to the initiation of treatment
for mild TBI can help to identify patients who may be at greater risk for poorer
rehabilitation outcomes, thus allowing for the implementation of specific
interventions to address these risk factors.
