Background: Successful aging is best determined by active management and self-determination of one’s aging roadmap. Some individuals are ready to respond to these challenges, others may benefit from assistance that might be offered through an evidence-based intervention. The Aging Mastery Program^® (AMP) has been developed to meet these needs. Method: In a cross over design the intervention was tested in ten senior centers and aging network agencies looking at impacts upon general health and quality of life, patient activation, physical activity and advanced care planning. Results: There was a statistically significant (tested at a 0.05 level) level of improvement found in physical activity and advanced care planning. Conclusion: Findings support the program’s effectiveness and its value as an evidence-based intervention for older adult programming.
