In the preschool phase of the study Dallas/Fort-worth Metroplex families were invited to participate in a fun, engaging study of early child behavior. The study included three online surveys and a laboratory visit. We enrolled families with twins or two siblings between 2.5 and 5.5 years of age. We recently completed a longitudinal follow-up study of TFS families whose children have reached elementary school. Participants in the longitudinal study answered questions in an online survey format and were compensated with Amazon gift cards.
