the interactionist approach Flashcards
what does the interactionist approach say
states that schizophrenia is a complete mix of biology, psychology and societal factors
explain what Meehl found (the original diathesis of stress model)
diathesis is entirely genetic
in carriers of the schizogene, stress in childhood could result in schizophrenia
this is now considered too simplistic
Modern understanding of diathesis of stress model explain it
there is no single schizogene, it is many combinations which increase genetic vulnerability
early psychological trauma can affect brain development making people more vulnerable to the effects of later stress
not just childhood stress but also cannabis can increase the risk of schizophrenia
how many times can using cannabis increase your risk of schizophrenia and how
seven times because it interferes with your dopamine system
what is the treatment according to the diathesis of stress model
a combination of antipsychotic medication and psychological therapy’s
why are a combination of therapy’s a good idea
its hard to carry out CBT, family therapy and token economy on patients experiencing severe symptoms
antipsychotic medication can be used to relieve symptoms allowing the patient to engage in family therapies more effectively
what are the evaluation points of diathesis-stress model
why was the original diathesis model oversimplified
why is a combination of treatments useful
the role of triggers
explain what is meant by treatment causation fallacy
explain the evaluation point that the original diathesis model is an oversimplified view of schizophrenia
multiple genes increase the genetic vulnerability to schizophrenia, stress can come in many forms not just dysfunctional parenting
Houston found that childhood sexual trauma is a vulnerability and cannabis is a trigger
this shows that the old idea of diathesis= biological + stress = enviromental is overly simplistic
explain the evaluation point combination therapy’s can be useful in the treatment of schizophrenia
Anderson found only 5% relapse rate when drug therapy and family therapy are used together
Tarier found that patients undergoing combination treatment had fewer symptoms than drug only or CBT only
explain the evaluation point role of triggers
children adopted from mothers with schizophrenia were studied
high levels of criticism and conflict with low levels of empathy within adoptive families was linked to development of schizophrenia but only in children with high genetic risk
explain what is meant by the treatment causation fallacy as an evaluation point for the diathesis of stress model
the fact that combined treatments are more effective than either on their own doesn’t mean necessarily that the interactionist approach to schizophrenia is correct. similarly the fact drugs help doesn’t mean that schizophrenia is of biological origin
just because something treats the symptoms doesn’t mean that the lack of it caused the symptoms
