ao3 evaluation interactionist approach

Question 1

strength of interactionist

Answer 1

research support, use children adopted from finnish parents with schizophrenia and parents assessed for their parenting style, compare to control group without genetic link, parenting style characterised by high levels of criticism and EE implicated development of schizophrenia but only with children with high genetic risk, strength because it gives direct support and shows there must be a genetic vulnerability and environmental trigger

Question 2

 limitation of diathesis

Answer 2

Oversimplistic, though schizogene and schizophrenic parenting style are the major source of stress, there are a range of genes that can cause a vulnerability, stress can be result of any trauma as well as genetic, limitation as diathesis stress model is reduction is in explaining what can cause schizophrenia which can cause doctors to mistreat patients and therefore labelling patients into them fulfilling a self-fulfilling prophecy

Question 3

strength of treatment

Answer 3

research support, researcher randomly allocated patients to drugs and CBT had lower symptoms when compared to those only took medication, strength because it shows it effective but only for short term, this is because there are no differences in rate of hospital admission therefore suggesting is not effective in the long-term, overcoming this we would need to incorporate family therapy

Question 4

A01 interactionist approach

Answer 4

acknowledges the biological psychological and societal factors in development of schizophrenia which combine and work together to predict how SZ develops

Question 5

A01 diathesis stress model

Answer 5

genetic/underlying vulnerability and a stress trigger from the environment are necessary to develop SZ

Question 6

older version of diathesis stress model ao1

Answer 6

MEEHL
- Believe diagnosis was entirely genetic and was the result of a single schizo gene, led to development of biologically schizotypic personality, One characteristic is sensitivity to stress so chronic stress can trigger genetic vulnerability

Question 7

modern version of diathesis stress model ao1

Answer 7

READ ET AL

• no single schizogene and there are a range of factors beyond genetics including childhood trauma as the brain because more susceptible to stress
• hypothalamic pituitary adrenal system (HPA), becomes overactive and the person becomes more vulnerable to later stress

Question 8

modern understanding of stress

Answer 8

anything that risks triggering SZ especially parenting
- cannabis becomes a stressor and childhood trauma becomes diathesis which increases the risk of SZ by seven times as it interferes with the dopamine system 

Question 9

treatment ao1

Answer 9

antipsychotics and CBT, family therapy may be better than CBT however Britain uses CBT and drugs with USA does not
-Turkington et al- can believe in biological causes and practice psychological treatment
