interactionalist approach to Sz Flashcards
(12 cards)
how do interactionalists explain Sz?
diathesis stress model
what is diathesis?
vulnerability
what is stress?
negative experience to trigger Sz
what was Meehl’s diathesis stress model?
diathesis = ‘schizogene’ (only those with this gene will develop Sz)
stress = stressful life (schizophernogenic mother)
what is the modern diathesis stress model?
diathesis = life event or ‘schizogene’
stress = anything can trigger it (nature, parenting, cannabis)
strength of interactionalist approach to explain Sz (evidence)
tienari - investigated impact of genetic vulnerability and psychological triggers on 19,000 finish children who have biological moms with Sz
- compared to control
- found high criticism, hostility, low empathy
- all related to development Sz
limitation of interactionalist approach to explain Sz (meehl- simple)
- meehl said one gene causes Sz which seems unlikely
- houston showed that childhood sexual abuse is a factor on vulnerability
- limits original diathesis stress model
what model do interactionalists use to treat Sz?
interactuonalist approach to explain Sz is correct so use same model to treat Sz
what are the interactionalist biological treatments?
- antipsychotic drugs (deals with vulnerability)
what are interactionalists psychological treatments?
- CBT helps to alleviate stressors (belief modification)
- family therapy encourages communication (relieve stress)
strength of interactionalist approach to treat Sz (combination)
tarrier- allocated 315 pps CBT + medication, counselling + CBT or just meds
- first two groups showed lower symptoms
- effective
limitation of interactionalist approach to treat Sz (same model illogical)
explaining Sz with this model is correct doesn’t mean that treating it with this model is also correct
- treatment causation fallacy (assume treatment must also be the cause)
