- methods of studying schizophrenia
- interviews
- can be structured, semi-structured or unstructured
- interviewer will find out about personal data
- martial status
- age
- gender
- employment status
- standard instructions are used at the beginning, so the respondent is aware of ethical issues
- right to withdraw
- confidentiality
- e.g. Goldstein
- twin studies
- involve comparing MZ and DZ twins to see what differences there are in the incidence of certain characteristics
- completely genetic (nature) = both MZ twins should show the characteristic comes from environmental influences (nurture) = MZ twins won't share the characteristic any more than DZ twins
- MZ = share 100% of their genes because they comes from one egg
- DZ = share 50% of their genes because they come from two eggs
- concordance: when one twin is found to have the same characteristic as the other twin
- If schizophrenia is inherited, when one twin has the condition, the other is more likely to suffer from it as well
- e.g. Goldstein
- involve comparing MZ and DZ twins to see what differences there are in the incidence of certain characteristics
- interviews
- DZ = share 50% of their genes because they come from two eggs
