A multidisciplinary team developed and pilot-tested a curriculum, delivered by trained lay educators, to increase self-efficacy for physical activity among elderly food stamp recipients. Curriculum development was guided by a comprehensive literature review. Process evaluation was used to revise the curriculum and to assess lay educator training and pilot test fidelity. Three hundred sixteen low-income older adults participated in curriculum development and pilot-testing activities. One hundred twenty four participants completed pretest/posttest impact evaluation surveys. The average age of participants was 75 years old with 55.28% having less than high school education. Significant increases in self-efficacy regarding walking most days (p = 0.0022), using exercise bands (p less than 0.0001), being physically active to increase strength (p = 0.0012), being active without injury (p less than 0.0001), being able to wear appropriate clothing and shoes (p less than 0.0001), and getting information about community physical activity programs (p = 0.0007) were observed. Participants also endorsed higher ratings of general health at posttest (p less than 0.0001). (Contains 3 tables.)
