Interactionist Approach to Schizophrenia Flashcards
(14 cards)
what is the interactionist approach to schizophrenia based on
the diathesis stress model
what is the interactionist approach to schizophrenia
the idea that it results from a combination of psychological, biological and social factors
how does the diathesis stress model explain schizophrenia
says it’s the result of an interaction between biological (diathesis) and environmental (stress) influences
which key study can be used to support the diathesis stress model for schizophrenia
Tienari et al
name the two research pieces that indicate schizophrenia has a biological component
- Gurling who found genes for schizophrenia
- twin studies
how did Gurling’s study support that schizophrenia has a biological component
found the chromosome 8p21-22 and gene PCM1 genetically increase vulnerability to schizophrenia
how do twin studies support that schizophrenia has a biological component
monozygotic twins have a greater concordance than dizygotic twins
what are the environmental influences that increase chances of schizophrenia
- family dysfunction
- substance abuse
- critical life events/ trauma in childhood
in a study what was the relationship between trauma and schizophrenia
children with severe trauma are 3 times more likely to develop schizophrenia as an adult
what about twin studies suggests there must be environmental influences on schizophrenia
in 50% of identical twins - if one gets SZ, the other never meets the diagnostic criteria for it (if just down to genetics both would have it)
what about genetic studies suggests there must be an environmental influence on schizophrenia
there is never 100% concordance rates
what geographical influence is there on schizophrenia
rural vs urban
what was found about the impact of urban life on schizophrenia
risk of SZ in urban environments is 2.37 times higher than the risk in rural environments
why do urban environments increase the risk of schizophrenia
urban stress
