AbstractThe aim of the study was to evaluate whether thought disorders are stable, trait-like features specific to subjects who have a genetic liability to schizophrenia or a psychiatric disorder. The thought disorders of adoptees genetically at high risk (HR) or low risk (LR) for schizophrenia from the Finnish adoptive family study of schizophrenia were evaluated twice at a mean interval of 11 years, using the sum of the Thought Disorder Index (TDI) scores on the Rorschach (TDR). At the initial assessment, the mean TDR scores of women were significantly higher than those of men, while no association between genetic risk and psychiatric status or their interactions with the TDR scores at baseline were found. The main finding was that the initial TDR scores statistically significantly predicted the TDR scores at follow-up, thus indicating the stability of thought disorder over time. However, neither genetic or psychiatric status nor gender or any interaction between these variables associated with TDR at follow-up.

In a study of children adopted at an early age, discrimination between hereditary and family dynamic factors is possible. The biological parents have given the child their genetic characteristics and sometimes the very early environment, while the adoptive parents have provided the more permanent family environment and rearing. The major goal of the Finnish adoptive family study was to re-assess the genetic contributions to schizophrenia and to provide further measures of the adoptive family rearing environment. In other words, we were interested in the joint effects of genetic and family environmental variables and in their possible contribution to both the psychopathology and the healthy functioning of adoptees during their development. This approach paid attention to the possibility that a healthy, possibly protective, rearing family environment may reduce the genetic risk. During the course of the study, we also considered whether the direction of the effects between genetic and family environmental factors can be clarified through a prospective, longitudinal study of the adoptees at risk.
