What important aspect of the adoptive family was missing from early studies? What did later studies find when they did
include it?
What will be an ideal response?
Early studies did not examine child rearing adequacy of the adoptive family. Newer studies found that
communication deviance - how understandable and easy to follow the speech of family members was - was
related to risk of schizophrenia. Children with a biological risk for schizophrenia who were adopted into families
with high communication deviance had an increased risk of the disease. If the child had no genetic predisposition
for schizophrenia, communication deviance did not make a difference in risk. Most interestingly, if a genetic risk
existed and the child was adopted into a family with low communication deviance, that child's risk for
schizophrenia was actually lower than the other groups!
