Roybal Center for Personalized Trials:

Physical Activity Promotion to

Foster Healthy Aging


About our Center

The goal of the Roybal Center for Personalized Trials: Physical Activity Promotion to Foster Healthy Aging is to focus on innovative, physical activity behavioral interventions aimed at promoting and improving the overall health and well-being of older adults through the conduct of fully powered, meaningful pilots. The Center’s specific focus will be Personalized (N-of-1 ) trials for Stage I intervention development, and a common battery of mechanisms of actions will be explicitly assessed where appropriate.

The first pilot project aims to efficiently identify the distinct, effective behavior change techniques (i.e., building blocks) that are preferred for improving low-intensity physical activity (e.g., walking) in older, otherwise healthy, community-dwelling adults to be included in later-stage multi-behavior change technique interventions. The second pilot project aims to formally test the habit-formation theory to improve walking in a second sample of older, otherwise healthy, community-dwelling adults by employing its behavior change techniques and hypothesized mechanism of action—cognitive automaticity. The projects’ success is contingent on the creation of a practical, science-based, prevention-driven suite of behavioral interventions that are successfully implemented in the real world to improve the health and vitality of older adults.
