Interactionist Approach Of SZ Flashcards
What is the interactionist approach?
An approach that acknowledges that there are biological, psychological and social factors in the development of SZ
What does stress mean in terms of the diathesis-stress model?
A negative experience
What is necessary in order to develop sz?
A vulnerability to sz and a stress-trigger
What makes a person vulnerable to developing sz?
One or more underlying factors but the onset of the condition is triggered by stress
In Meehl’s model what was diathesis?
Entirely genetic which led to the idea of a biologically based schizotypic personality - one characteristic sensitive to stress
According to Meehl what happens if a person doesn’t have the schizogene?
No amount of stress would lead to SZ but in carriers of the gene chronic stress throughout childhood and adolescence particular the schizophrenogenic mother could result in developing sz
what is one way in which our understanding of diathesis has changed?
It’s now clear that many genes each appear to increase genetic vulnerability only slightly - no single schizogene
What do modern views of diathesis include?
A range of factors beyond genetic including psychological trauma which in this case trauma becomes the diathesis rather than the stressor
What did Read et al propose?
A neurodevelopmental model in which early trauma alters the developing brain early and severe enough trauma can affect many aspects of brain development
What is an example of how early and severe trauma can affect brain development?
Hypothalamic pituitary adrenal system can become overactive making a person more vulnerable to later stress
How was stress originally seen?
Psychological in nature particularly related to parenting.
Why is cannabis a stressor of SZ?
It interferes with the domaine system however most dont develop SZ after smoking cannabis so there must be other vulnerability factors.
What is the interactionists approach to treating SZ?
Combining antipsychotics with psychological therapies such as CBT - this is the standard practice in the UK.
What does Turkington et al point it is possible to believe in?
Biological causes and practice CBT to relieve symptoms but this requires adoption an interactionists approach.
