Interactionist approach Flashcards
(13 cards)
What does the interactionist approach suggest?
It suggests that schizophrenia is developed due to a combination of biological, physiological and social factors. This is known as the diathesis-stress model
What is a diathesis?
Vulnerability
What is a stress defined as?
A negative psychological experience
What did Mheel’s original model state?
This model stated that diathesis was entirely ginetic and it was down to a single ‘schizo-gene’, which made someone sensitive to stress
Wheel suggested that if a person does not have this schizo-gene then…
No amount of stress would lead to schizophrenia. However, if you have the gene, stress through childhood, such as a schizophrenogenic mother could lead to SZ
What is now believed about the schizo-gene?
It is now believed that there is no schizo-gene, but there are many genes that increase ginetic vulnerability to schizophrenia
Schizophrenia is…
Polygenic
What is an example of a gene that can increase ginetic vulnerability to schizophrenia?
PCM1
What is now believed about diathesis?
Other factors can be a diathesis such as psychological trauma. Early and severe enough trauma, such as child abuse can seriously affect aspects of brain development and can make a person more vulnerable to stress
What is the modern explanation of stress?
A modern definition of stress included anything that risks triggering schizophrenia, not just parenting
What has research suggested can be a stressor increasing risk to sz?
Cannibis use which is the stressor because it increases risk to sz up to 7 times according to the dose
Why does cannabis use increase vulnerability to sz?
Due to it’s interference with the dopamine system
Why must there be more vulnerability factors than just cannibis?
Because not everyone develops schizophrenia after smoking cannabis
