Montessori-Based Dementia Programming® (MBDP) is a method of creating and presenting activities/interventions. The Myers Research Institute conducted several studies, each of which involved the use of MBDP in a different setting/situation. Staff members from nursing homes, adult day centers, and assisted living facilities were trained to implement MBDP, as were family members and even persons in the early stages of dementia. In addition, a Montessori-based assessment tool is being developed for use in restorative nursing for persons with moderate to advanced dementia. An overview of each study is provided, as are the findings and implications of each study.
