Parents also complete a few forms. Students and parents receive modest compensation in the form of gift certificates for their efforts. In the extended phase of the Teen Sleep Study, about one third of the students who participate in the autumn are invited to take part in a more intensive study lasting from January to mid-May. Parents complete a few forms on two occasions in the extended phase. Because of the increased time commitment, compensation for this longer part of the study includes gift certificates for students in the larger amounts for each succeeding 4 weeks of participation, cash payments for in-lab visits, and a savings bond is awarded upon successful completion.
Parents receive a small gift certificate each time they complete forms.
