S2K Study FAQs

Duke child development experts are validating a new app that parents can use at home to track children’s development.

  • Infant-toddlers who are 5-36 months old
  • Infant-toddlers referred from the Durham CDSA who are 5-36 months old
  • All other 5–12-month-old Infants who currently live in North Carolina
  • Children must be able to see and hear the movies shown on the app

You will need access to an iPhone or iPad to complete the S2K app. You can either own your own device or borrow one from a friend or family member.

Depending on when your family starts the study, we will ask you to download and complete the S2K app and a few short questionnaires when your child is 6-, 9-, 12-, and 16-months of age. The S2K app takes less than 10 minutes to complete and is fun for kids to watch! The S2K app and parent surveys can be done on your own, but our staff are always available for any questions you may have.  

No, study activities can be done remotely from your home. However, if you cannot complete the app remotely, or if you would prefer to complete the app in person, we may invite you to a short visit at our research center.

Yes, families receive small toys and prizes for completing the app. In addition, families earn tickets to a monthly raffle by completing study activities such as questionnaires. Raffle prizes range from $75-$500!

If developmental concerns are raised by a parent or the child’s pediatrician, children may receive a developmental evaluation conducted by a licensed psychologist. This evaluation is completed when the child is between 16-36 months and is provided at no cost to the family.

Yes, we would welcome your participation! Collecting the same information from a variety of infants and toddlers will help us better understand children’s behavior and development in infancy and early childhood.
