Interactionist Approach Flashcards
what is the interactions approach
combination or biological, psychological, and social factors for schizophrenia development
what is the diathesis stress model
diathesis= vulnerability
vulnerability to schizophrenia and stress= schizophrenia develops
original understanding
Meehl (1962) diathesis is purely genetic (schizogene)
-development of biologically based ‘schizotype personality’
-no schizogene= no schizophrenia
-can be triggered through chronic stress in childhood and adolescence
modern understanding
-schizophrenia is polygenic, many genes increase genetic vulnerability
-non genetic factors can also form a diathesis to be triggered
-Read (2001) early trauma changes brain development
-houston (2008) psychological stress as well as anything else that risks triggering schizophrenia
-cannabis use- increases risk by 7x and interferes with dopamine system
Turkington et al (2006)
it is possible to use biological model while using psychological treatments to aid coping
-recognises the importance of psychological treatments alongside biology
AO3 research support
tienari (2004) investigated the impact of genetic vulnerability and psychological trigger
-19000 finnish children with schizophrenic biological mother (high risk)
-compared to control group of adoptees (low risk)
-adoptive parents assessed for child rearing styles
~>high criticism and hostility, low empathy associated with schizophrenia development
-combination of genetic vulnerability and family stress leads to increased risk
AO3 oversimplified model
-original model, singular gene but multiple genes and combinations actually influence schizophrenia
-can also be influenced by psychological as well as biological
Houston (2008) childhood SA was major vulnerability, cannabis was a trigger
-multiple factors influence schizophrenia
AO3 real world application
-combination of drug treatment with psychological therapies enhances effectiveness
Tarrier (2004) randomly allocated 315 patients to:
-> medication + CBT
-> medication + counselling
-> medication only (control)
two combination groups showed lower symptoms- practical advantage
AO3 real world application counterpoint
Jarvis and Okami (2019) successful treatment for mental disorders doesn’t justify a particular explanation
-treatment causation fallacy- cannot assume that success of combines therapies means interactionist approach is correct
assumptions of interactionist approach
combination of biological, psychological, and social factors for the development of schizophrenia
what is the diathesis stress model
diathesis = stress
-vulnerability to schizophrenia + stress trigger= schizophrenia develops
