Study evaluated the internal consistency of the Mayo-Portland Adaptability Inventory (MPAI) in a national sample of people with acquired brain injury and used Rasch, item cluster, traditional psychometric, and factor analyses to further refine the instrument. After recoding 4 items and eliminating the child-rearing item, the revised MPAI showed satisfactory internal consistency by Rasch measures as well as by the more traditional psychometric alpha coefficient.
