TL;DR: In adoptees at high genetic risk of schizophrenia, but not in those at low genetic risk, adoptive-family ratings were a significant predictor of schizophrenia-spectrum disorders in adopts at long-term follow-up, and are significantly more sensitive to adverse v. ‘healthy’ rearing patterns in adoptive families than are adoptee at low Genetic risk.

TL;DR: A nationwide Finnish sample of schizophrenics' offspring given up for adoption was compared blindly with matched controls, who were adopted offspring of non-schizophrenic biological parents, and the impact of disturbed family relations was strongest in the presence of the appropriate genotype.

TL;DR: There is no evidence that high genetic risk of schizophrenia among offspring is associated with high levels of communication problems in rearing parents, and the findings are consistent with genetic control of sensitivity to the environment.

TL;DR: A strategy for research on schizophrenia in which the focus is upon links between family patterns and structural aspects of schizophrenic impairment, especially upon thought disorder is described.

TL;DR: The study demonstrates that life event methodologies originating in the developed countries can be adapted for international studies and may be used to collect reasonably reliable and comparable cross-cultural data on psychosocial factors affecting the course of schizophrenic disorders.
