The CHAMPS program was developed and tested scientifically in three phases.  For each phase, we describe the program components, research design, and funding.   

• CHAMPS I: Demonstration project for seniors in low-income housing
• CHAMPS II**: Main program - randomized controlled trial in a Medicare HMO (manualized)
• CHAMPS III: Diffusion to reach seniors in diverse community settings

**CHAMPS II is the main program, tested in a large sample of older adults using a randomized controlled trial design.  It is based on the CHAMPS I developmental work and was later diffused into three community settings to reach minority (primarily Latino and African American) and lower income seniors (CHAMPS III).  The publications page lists our publications for each phase as well as on promoting physical activity in older adults.
