The Lighthouse, Inc. uses a standardized assessment, the Mayo-Portland Adaptability Inventory (MPAI-4 or MPAI). The Mayo-Portland Adaptability Inventory is a formal assessment designed to:
assist in the clinical evaluation of individuals with an acquired brain injury
to assist in the evaluation of rehabilitation programs designed to serve individuals with an acquired brain injury
to develop a standard measurement/rating system that will assess an individual’s level of functionality
The MPAI-4 evaluation measures a client’s: physical health, psychological (emotional) health, and social relationships. The final measurement of each subscale is combined and adjusted to provide a reliable prediction of the client’s functional change over time. Overall, the MPAI-4 assessment is designed to aid in identifying the barriers to community integration that individuals with a brain injury may experience. Simply stated, the basic MPAI-4 evaluation measures the client’s rehabilitative changes over time.
