supporting research from tierni et al
supporting research comes from tierni et al who studied the biological children of schizophrenic children that had been adopted. she found that adopted children from families with schizophrenia had more chance of developing sz than children from a normal families. furthermore, 36% of children raised in dysfunctional family households went on to develop schizophrenia compared to only 5.6% that were raised in healthy families.
what did gottesman find in his meta analysis of cases of schizophrenia
research by gottesman found a 48% concordance rate for identical twins and 17% for non identical twins. this suggests the role of biological factors as the concordance rate is much higher for twins that share 100% DNA . however, since the concordance rate is lower than 100%, this indicates that some psychological factors are necessary for triggering the condition
what does the supporting research from tierni et al suggest about the importance of both biological and psychological factors
this research supports the influence of biological factors due to the high rate in healthy families. nonetheless, the even higher rate for dysfunctional families suggest a psychological trigger is needed
