interactionist approach Flashcards
Interactionist approach
biological factors & psychological factors
diathesis-stress model
- vulnerability to schizophrenia+ stress trigger = increased chance of schizophrenia
diathesis-stress model: original hypothesis
- having a gene and chronic stress in childhood (such as a schizophrenogenic mother)= increased chance
diathesis-stress model: modern understanding of diathesis
- many genes cause schizophrenia
- other factors other than genes makes someone vulnerable such as
- early & severe trauma which affects the developing brain
- affects stress system (hypothalamic pituitary adrenal pathway HPA)
- makes someone vulnerable to later stress
diathesis-stress model: modern understanding of stress
- stress isn’t just related to parenting but its a stress factor
- stress could be the use of THC rich cannabis
- most don’t develop schizophrenia because they don’t have the vulnerability factors
- high dose of THC-rich cannabis can trigger schizophrenia for those vulnerable
AO3: evidence for the role of vulnerability & trigger (S)
Tienari et al (2004)
- looked at the combination genetic vulnerability & parenting style
- adopted children from 19,000 Finnish mothers with schizophrenia from 1960 & 1979 were followed up
- adoptive parents were assessed for child-rearing style & rates of schizophrenia
- child rearing style with low empathy & high criticism and conflict was found in development for children with high genetic risk
- suggest genetics & family stress are important with the development
AO3: original diathesis-stress model is too simple (W)
- many genes cause schizophrenia and not just 1
- stress comes in various forms ( such as the use of cannabis)
- cause of vulnerability is also early trauma
Houston et al (2008): suggest that childhood sexual trauma is a vulnerability factor
- both suggests that vulnerability & stress don’t have one single cause
- idea that vulnerability is biological & stress is psychological is too simple
AO3: real-world application - treatment (S)
Terrier et al (2004)
- 315 patients randomly allocated to either a) med & CBT b) meds & supportive counselling c) only meds
- patients in a & b showed lower symptom levels
- no difference in hospital re-admission
- shows clear advantage of using interactionist approach
AO3: urbanisation (S)
- more cases of schizophrenia in urban areas
- used to justify interactionist approach as urban living is seen to be more stressful and can act as a trigger
- more likely that its diagnosed in cities
- those vulnerable (teens abused as kids) tend to migrate to cities in looks for things such as jobs
AO3: treatment - causation fallacy (W)
Jarvis & Okami (2019): says just because interactionist approach to treatment works doesn’t mean that it’s cause
- same as saying that because alcohol reduces shyness , its caused by a lack of alcohol
