Abstract:
Study examined the internal consistency, reliability, and comparability of the Mayo-Portland Adaptability Inventory (MPAI) and its subscale measures for ratings made by people with acquire brain injury, their significant others, and by rehabilitation staff. Rasch analysis was used to determine the internal consistency of the overall measure and the 3 subscales (ability, adjustment, and participation indices) for each rater group and for a composite measure based on all rater groups. Rater agreement for individual items was also examined. Results indicated satisfactory internal consistency for the MPAI regardless of the rating source. Item agreement was generally acceptable; disagreements suggested various source of bias for specific rater groups.
