L12: Interactionist Approach in Explaining And Treating Schiz Flashcards
Define the interactionist approach
A broad approach to explain schizophrenia, it looks at both bio and psych factors that cause schiz and for treatment of schiz
What is the diasthesis stress model?
Schiz is caused by both bio and psych factor. Neither alone causes it.
What can you write for AO1 of the interactionist approach for causing schiz?
L4 - Ripke and his genes
AO3: discuss the evakuation of that lesson
What was research for the diathesis stress model? (Explaining schiz from env)
Murray:
- Investigated children born after a flu epidemic
- Bio moms had flu when they were 4-6 months preggo
- 88% increased chance of having schiz
- It caused defects in neural development, leading to brain damage and problems with dopamine functioning
What was research for the diathesis stress model? (Explaining schiz from bio)
Durand:
- Studied patients who had a family history of schiz
- Genetic link is a important factor but a stressor was needed
Evaluation (explaining schiz)
(+) Stress causes schiz. Cortisol levels were very high before onset of schiz, so stress might cause schiz
(+) Genes cannot alone cause schiz as concordance rates are not 100%. They increase the vulnerability risk but env is needed for gene expression
(+) Patients w/ Schiz had childhood sexual trauma - seemed to effect brain development. Patients were stressed and took cannabis, increasing chances of getting schiz
(-) Individual differences. A range of stressors cause schiz and patients have different tolerations of stress + coping
(-) Diathesis Stress doesnt have one source e,g multiple genes can cause schiz, but stress can mean a lot of things and encompasses many factors like poor parenting.
How does the interactionist approach treat schiz?
- Combine bio + psych treatments
- See which combos are suitable for individuals
- Drugs given first, then treatment
Research on treatment
- 103 schiz patients with high EE families were studied
- Treat,ents offered and relapse was measured
- 19% relaspe for family therapy + drugs
- 20% relapse for social support + drugs
- 41% relapse for drugs
- 0% relapse for family therapy, social support + drugs
AO3 of treating schiz with interactionist app
(+) Combining behavioural and cofnitive therapies. Cog aims to change disordered thinking, allowing behavioural therpaies to beh effective
(+) As schiz has bio and psych causes, it makes sense to treat them biologically and psychologically e.g dopamine = drugs & bad families = family therapy
(-) Expensive and costly, not everybidy will have access to it, even if more effective.
(-) 1+ treatment can cause more side effects and can interfere in therapies. They might stop taking drugs and attending therapies, making their symptoms worse
