EvaluationThis approach fails to incorporate genetic factors that clearly play a role in schizophrenia. For example, Gottesman (1991) This suggests that genes play a significant role in causing schizophrenia, as MZ twins are genetic clones, whilst DZ twins share found 50% of their DNA. Thus, assuming environment is similar for twins, any increased concordance rate amongst MZ twins is due to greater genetic similarity. As a result, any valid explanation of schizophrenia should incorporate biological and psychological factors. For example, the diathesis-stress model, which proposes that an underlying predisposition (such as the genetic history of schizophrenia) will result in the development of schizophrenia only in people who also experience a stressor (such as cognitive dysfunction). |
