Playdates: A Win-Win-Win Strategy for Recruitment of Infant Participants

High-quality developmental science requires a reliable and representative stream of participants, yet recruiting infants at a satisfactory rate can be challenging. We recently developed a new recruitment technique: we invite parents to sign up for no-strings-attached playdates in our laboratory, where we provide toys, free coffee, and students to help entertain the children. We have consistently hosted 2-3 new parents per week via playdates. Approximately 88% of attending parents agreed to be contacted later about research, and 81% of those contacted returned for research appointments. This method has doubled the number of participants we run per week, improved our rapport with the local community, and provided an enhanced educational opportunity for students in our laboratory. We hope others find it similarly transformative.
