⭐️interactionist approach to SZ✅

Question 1

what does the interactionist approach acknowledge?

examples of biological?

examples of psychological?

Answer 1

• there are biological, psychological and societal factors in the development of sz
• eg. genetic vulnerability, neurological abnormality
• eg. poor interactions with family

Question 2

what is the diathesis stress model?

Answer 2

diathesis = vulnerability
stressor = trigger 

• the model suggests both vulnerability and a stress trigger need to be present for someone to develop sz

Question 3

Meahl’s model:

what was the original DSM? what did this lead to?

what did meahl say about the gene and and stress?

Answer 3

• entirely genetic and the result of a single ‘schizogene’ … led to the devilment of a biologically based schizotypic personalty
• it doesn’t matter how stressed someone gets, if they dont have the vulnerable gene they wont develop sz

Question 4

modern understanding of diathesis:

what was found out about how many genes there needs to be to develop sz?

what do modern views contain?

what was the neurodevelopmental model?

Answer 4

• has to be multiple genes to increase vulnerability, not just one schizogene
• factors beyond genetic such as psychological trauma since it becomes the diathesis instead of the stressor
• claims early trauma in life alters the developing brain

Question 5

modern understanding of stress:

definition of stress

what has research research found about drug use?

why its canibis seen as a stressor?

Answer 5

stress = anything that risks triggering sz

• when looking into factors triggering sz episodes, cannibis was linked
• it increases the risk of sz up to 7x depending on the dose bc it effects the functioning of the dopamine system

Question 5

TREATMENT:

how do interactionists attempt to treat sz

what does Turkington et al believe?

Answer 5

• any combining biological (antipsychotics) and psychological (CBT)
• he said that sz caused by biological factors. but you can treat it with psychological treatments such as CBT .. its not possible to adopt a purely biologcxla approach

Question 6

TREATMENT:

what is uncommon when it comes to treatments?

example

Answer 6

uncommon to treat sz with just psychological therapies alone. mostly accompanied by biological medication

eg family therapy and antipsychotics

Question 7

ao3:

✅ strength for explanation, strength for treatment ?

❌ weakness:?

Answer 7

✅ explanation- Evidence for the role of vulnerability and triggers. tienari investigated the combo of genetic vulnerability and parenting style. Children adopted from 19,000 Finnish mothers with SZ. Their adoptive parents were assessed for child rearing style and the rates of sz were compared to those in a control group of adoptees without any genetic risk. rearing styles where characterised by high conflict and low empathy, which are implicated in the development of sz but only for those who are at a genetically high risk

✅ treatment - evidence ew to support, tarrier looked at ppl with sz randomly allocated into 3 groups
1) meds and CBT
2) meds and counselling
3) control group (meds)
found the two combination groups has lower symptom of sz, showing the importance of the interectioinst approach and combo of treatments

❌dk how exactly diathesis and stress work. we have well informed suggestions for how vulnerabilities and stress may lead to the symptoms however se don’t fully understand the mechanisms by which the symptoms appear and how stress produces them. the diathesis stress model better accounts for individual differences especially for those who have similar genes e.g. MZ twins where one develops sz and the other doesn’t. this is explained by having different life experiences. therefore the diathesis may be triggered in one twin but not the other
