Overview
This study will test the validity and feasibility of an smartwatch-based system to detect eating and drinking events in both laboratory and free-living conditions.
Detailed description
The study will: 1) determine whether the smartwatch-based system accurately detects eating events in child-parent dyads in controlled settings and 2) evaluate the feasibility and practicality of passively detecting eating events in child-parent dyads over 3 days in free-living settings. The study will include two phases. During the laboratory visit, child-parent dyads will wear the smartwatch on their dominant hand and perform activities including eating gestures. These activities will be recorded with a video camera, and the videos will be coded for the ground truth times of eating. In the second phase of the study, child-parent dyads will continue wearing the smartwatch for 3 more days in free-living conditions. In the free-living period, parents will receive personalized Ecological Momentary Assessment (EMA) prompts reminding them to activate the smartwatch.
Interventions
- Other Smartwatch and EMA-based eating behavior tracking
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 m
Primary outcome measures
- Accuracy and Performance of Smartwatch-based Eating Detection System in Controlled Conditions [Time frame: During the controlled laboratory session (Day 1).]
- Adherence to Smartwatch Protocol [Time frame: During the free-living phase (Days 2-4).]
