What will be asked of you

The process would begin with a visit to our office in which a member of our staff would ask you and your child questions and have you and your child complete surveys on a computer. You and your child would each receive $75 in gift cards for this interview visit, which lasts about 3 hours. At the end of this visit, you would also receive urine test strips and an ovulation kit to measure their hormones and ovulation. You would also receive instructions on setting up your child's phone so they can answer a few questions every day for 70 days, 6 days of daily surveys, and one day of weekly surveys during the 70-day period. The weekly surveys will continue after the 70-day period for a 16-week follow-up period. We will give your child $1 for each of the 60 daily-diary surveys they complete, and an additional $20 for completing at least 80% of these daily check-ins (i.e., up to $80 total). Next, we will give your child $4 for each of the 26 weekly follow-up surveys, and an additional $41 for completing at least 80% of these weekly surveys (up to $145 total). In addition, we will give your child $3 per correctly taken and stored at-home urine test (up to $120 total). In total, your child can earn up to $570 in prepaid debit cards for their participation in this project.
