tiearni et al
- Reviewed hospital records of 20,000 women diagnosed with SZ.
- Identified mothers who had one or more children adopted away.

- Both groups assessed at 12 and 21 years old.
- Family functioning also assessed.

- of the 300 adoptees, 14 developed SZ over the course of the study
- 11 were from the high risk group
outline gottesmans research
- reviewed SZ cases
- 48% concordance rate in identical twins
- 17% for non identical
