The social support from SBTs can increase intrinsic motivation to engage in and sustain positive health behaviors. Guided by technological affordances and self-determination theory, this study tested the long-term efficacy of an ecosystem of SBTs to strengthen social support for children\u2019s behavior change, children\u2019s perceived relatedness, and positive physical activity (PA) attitudes. This ecosystem integrated Fitbits tracking each child\u2019s PA, kiosks with virtual agents that synced with Fitbit data, and a messaging system for parents and children. Afterschool programs (N\u2009=\u200919) were randomly set with this ecosystem or a Fitbit with a computer for 6 months. Results suggested that parents of girls provided more social support to children via the ecosystem than parents of boys. Children\u2019s perceived support from the virtual agent was positively associated with perceived relatedness and PA attitudes over time.<\/jats:p>","DOI":"10.1093\/jcmc\/zmad011","type":"journal-article","created":{"date-parts":[[2023,8,23]],"date-time":"2023-08-23T11:23:32Z","timestamp":1692789812000},"source":"Crossref","is-referenced-by-count":6,"title":["Mediating
