Spectra Discovery

Spectra Discovery is a research study looking to see if wearable devices can measure screen time use in children ages 3 to 8. Your child will wear fake glasses and a shirt clip with light sensors to track light from screens. They will also wear an activity counter around their waist to track movement. During the study, your child will use a study-provided Android tablet, which includes an app to track screen use. The study lasts one week and includes: a baseline survey, daily time-use surveys, device logs at the end of each day, and a follow-up survey. To get started, parents will complete an online baseline survey and schedule an in-person orientation, either at home or at our Chapel Hill office. Families will be compensated for their time, and children will receive a thank-you gift. This study helps us learn if these wearable devices can measure screen use in young children.
