Final answer:
Children of schizophrenic parents are still more likely to become psychotic even if raised away from their chaotic home environment. Extensive research, including a study by Tienari et al., indicates that genetic factors play a significant role, and the risk is moderately reduced in a healthy environment.
Step-by-step explanation:
When the children of schizophrenic parents are raised away from their chaotic home environment, these children are c. still more likely to become psychotic. This is based on research studies which indicate that individuals with a high genetic risk for schizophrenia, such as having a biological parent with the disorder, have an increased likelihood of developing schizophrenia or other psychotic disorders despite being raised in different environments. Particularly, a 2004 study by Tienari and colleagues demonstrated that of adoptees whose biological mothers had schizophrenia and who were raised in disturbed family environments, 36.8% were likely to develop schizophrenia. However, even with a high genetic risk, when adoptees were raised in healthy family environments, that likelihood was reduced to 5.8%. Regardless, it was still higher than the likelihood of individuals with a low genetic risk developing schizophrenia in any environment.
