Interventions

  • Smartwatch and EMA-based eating behavior tracking — OTHER
    Participants (child-parent dyads) will wear a smartwatch on their dominant hand during a laboratory session and for three days in free-living conditions. In the lab, dyads will perform eating-related activities (e.g., eating with utensils, eating with hands, drinking) and non-eating activities (e.g., walking, writing, brushing teeth) while being video recorded for ground truth validation. Parents will receive a 20-minute training on using Ecological Momentary Assessment (EMA) prompts to record meal and snack times and will respond to EMA reminders during the free-living period. Adherence will be monitored through smartwatch wear time and EMA response rates.

Study Details
