SIBS is now in its second follow up phase, which is being conducted completely over the phone! Adolescent and young adult siblings are being asked to complete an interview assessment along with some follow up paperwork. Most of our siblings are now young adults (ages 19-26), and many are living or studying across the country. This next follow up is very important because we are particularly interested in learning how relationships with family and friends during adolescence influence adult development. All SIBS study participants are being contacted for participation in this assessment. Participants will be compensated and can set up the interviews at a convenient time.
