twin brothersCall for research participants

We are recruiting siblings in the 5th, 6th, 7th, or 8th grade, as well as their primary caregiver* to participate in our online study of youths' peer relationships, emotions, and behaviors. Participating families can earn up to $60. Each sibling can earn $20 for completing a survey, and their primary caregiver can earn an additional $20 for completing a similar survey. The survey takes each person about 1 hour to complete online.

To be eligible for the study, the siblings must
1) be full-siblings (including twins), half-siblings, or step-siblings,
2) both be in 5th, 6th, 7th, or 8th grade, and
3) have lived together for at least 2 years.
