Recruitment and screening of the evaluation cohort
RECRUITMENT
We propose to recruit 50 participants per development in the evaluation cohort. Eligibility criteria include being able to speak English or Spanish, being 18 years old or older, being a public housing resident from one of our study sites, not planning to move within the next 2 years, having access to a phone, not currently participating in another physical activity study, being able to walk independently without regular need for special equipment (wheelchair, scooter, or walker), ability to provide informed consent, and willingness to complete the accelerometer-based device measurement. By design, the entire cohort will be low-income.Recruitment will take place at the developments, using common sampling rules and a direct household door-knocking approach [
