ABSTRACT: Post-hospital brain injury rehabilitation programs are afforded limited time to reduce chronic disability resulting from acquired brain injury. Therefore, the purpose of this study was to identify deficit areas resulting from acquired brain injury that have the greatest impact on functional outcomes to enable greater efficiency in rehabilitation programming. Study participants were 1717 persons with acquired brain injury treated in residential post-hospital rehabilitation programs. Participants were assessed at admission and discharge on the MPAI-4. Functional status at discharge was evaluated based on T-scores derived from MPAI-4 discharge participation index items: Initiation, self-care and residence. The data base of 1717 was randomly divided into two subsets. Items from admission Abilities Index and select person variables were entered into stepwise multiple regression on subset one and then in a hierarchical multiple regression on subset two. Rash analysis demonstrated satisfactory construct validity and internal consistency of admission and discharge MPAI-4 evaluations (Person reliability > 0.90, Item reliability = 0.99). Both regression analyses revealed that Mobility and Novel Problem Solving accounted for 40% of the variance in functional outcome, p
