Question 5

what is the A03 for the interactionist approach

Answer 5

supporting evidence from tiernari et al- investigated the combination of genetic vulnerability and parenting style. children adopted from 19k finnish mothers with schizophrenia between 1960-79 were followed up. adoptive parents were assesed for child rearing style, rates of schizophrenia were assed to those in a control group of adoptees with no genetic risk. a child rearing style of high criticism and low levels of empathy was implicated in the development of schizophrenia but only for those with high genetic risk.

large sample size

low population validity

original DST model is over simplistic-multiple genes cause schizophrenia theres no singular gene

new model is holistic

research support for the treatment-315 patients were randomly allocated to a group with CBT and medication or a control group- with medication only. patients with combined treatment showed lower symptoms than those in the control group
