The TEXAS Family Study

Welcome to the TEXAS Family Study! We are now inviting TFS families to participate in a longitudinal follow-up study as children transition to elementary school.

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 are in the process of contacting TFS families who are eligible to participate in the longitudinal follow-up to the preschool phase. Eligibility is determined by age of the child (should be enrolled in school). Participants in the longitudinal study will answer questions in an online survey format and will be compensated with Amazon gift cards.

Participating families (longitudinal study) will be given a $20 gift card for completing 3 online surveys (family, parent, child 1), and then another $20 gift card when they complete the 4th online survey (child 2).
