Sibling Interaction and Behavior Study (SIBS)
About the study
The Sibling Interaction and Behavior Study is a study of 409 adoptive and 208 non-adoptive families to complement the MCTFR twin studies. In the latest follow-up with the SIBS cohort, we are interested in health, relationships, and childhood experiences in the full cohort of over 2,300 SIBS participants.
Who we are contacting for this study
All SIBS families are being recruited as part of this new follow-up.
Study Assessments
In a new assessment of SIBS funded by the National Institutes on Aging, areas of study include personality, demographics, relationships, and childhood experiences. Additionally, participants are invited to the Institute of Child Development for a physical health assessment and a blood draw.

FAQs
What is the Assessment like?
Our Remote Assessments are conducted over the phone and take approximately 5 hours to complete. You receive an assessment package mailed to your home address that includes materials that will be used during your assessment and a Clin Card for compensation. The follow-up to the Remote Assessment is an In-Person Assessment at the Institute of Child Development that takes approximately 1-2 hours to complete.
What if I cannot come to the University for the In-Person Assessment?
Our Remote Assessment is independent of the In-Person Assessment. You are able to fully participate in the Remote Assessment without visiting the University of Minnesota. You have the option to participate in the In-Person Assessment at a later date if it doesn't fit your current schedule.
How will I be compensated for my participation?
We provide compensation via a Clin Card, a prepaid MasterCard Debit Card that can be used wherever MasterCard is accepted, including having the card cashed out at a bank.
Will I receive personalized results from my participation?
Brain teasers that you complete as part of the assessment can be provided upon request. We are unfortunately unable to provide detailed personalized results as a result of the nature of large scale, longitudinal research.
Can I participate even if my other family members do not?
Yes, while a major aim of the study is to assess entire families, each interview is an individual assessment that does not require your family members for you to participate.
What are you doing with my DNA?
A major aim of this study is to assess the impacts of underlying genetic factors, shared, and non-shared environments. All collected DNA samples are deidentified and not tied to any personal information.
What if I am too busy to participate right now?
Our assessment project period spans multiple years of data collection. If you find yourself interested but unable to participate at this time, we can work to find a time in the future that will work with your busy schedule.
