Studies designed to disentangle genetic and environmental variables in schizophrenia: some epistemological questions and answers
SS Kety
The author addresses questions raised by Dr. Lorna S. Benjamin in the
preceding paper. He quotes from the original studies to respond to
questions regarding statistical logic, the relative prevalence of
schizophrenia among half-siblings and parents of index adoptees, and the
possible role of socioeconomic status as a confounding variable.
