Implication

Adoption study reveals increased psychopathology in biological offspring of schizophrenic parents but not crossfostered adoptees, indicating a primary role for genetic over familial rearing factors.

Key Points

To determine the relative contributions of genetic vulnerability and familial rearing environment to the etiology of schizophrenia using a crossfostering adoption strategy.
Compared adopted-away offspring of healthy biological parents raised by schizophrenic adoptive parents (crossfostered group) with two comparison cohorts.
Evaluated adopted-away offspring of healthy biological parents raised by healthy adoptive parents and adopted-away offspring of schizophrenic biological parents raised by healthy adoptive parents.
Identified a significantly greater prevalence of psychopathology among the adopted-away offspring of schizophrenic biological parents.
Found no elevated prevalence of psychopathology in the crossfostered group raised by schizophrenic adoptive parents, indicating that familial psychopathology during rearing does not drive schizophrenia risk.
