This project will determine the preliminary efficacy of an innovative intergenerational intervention among Head Start preschoolers, aged 3-5 years, and their caregivers. A two-group cluster randomized controlled trial will be conducted. Six Head Start centers will be randomly assigned to the intervention (n=3) or control group (n=3), and an average of 6 caregiver-preschooler dyads will be recruited from each class (N=144 dyads from 16 classes). Grounded in an Actor-Partner Interdependence Model, the 16-week intervention has 3 components: 1) a caregiver component, including 1a) a Facebook-based program with weekly electronic retrievable flyers providing health information and behavioral change strategies and 4 weekly habit-formation tasks to improve parenting practices and home environment for preschoolers; and 1b) 3 face-to-face or virtual meetings (weeks 1, 8, \& 16) to establish personal connections and communication networks among caregivers, discuss strategies, and share community resources to support preschoolers' behavioral changes at home; 2) a caregiver-preschooler learning component via Facebook messenger to send preschooler letters to each caregiver privately by the research team twice per week to 2a) share the preschooler's experiences of learning at school and his/her interests for a healthy diet and physical activity at home, and 2b) elicit caregivers' response to the letters; and 3) a Head Start center-based preschooler component to help preschoolers establish healthy habits via weekly healthy diet and physical activity participatory learning.
