Interventions
- BehavioralHealthy Together ("Juntos")
Parent-adolescent dyads will log in to a secured website for six months. The intervention will be delivered primarily through smartphones and will include didactic content on healthy lifestyle behaviors (for parents/adolescents), family behavior change content for setting weekly goals and self-monitoring health behaviors (for parents/adolescents), and positive parenting content (for parents only), all of which were developed in accordance with participant feedback based on formative intervention development work. In addition, and to increase participant compliance/reduce attrition often observed in digital health interventions, human support ("supportive accountability") will be provided. Specifically, each family will be assigned a "coach" who will use video conferencing software to engage in approximately weekly (during the first 3 months), and monthly (during the following 3 months) 20-30-minute sessions regarding the family's progress throughout the intervention period.
