2 psychological explanations
of schizophrenia (AO2)
- Face validity
- cognitive models such as Frith and
Hemsley's have provided a way of explaining
many if the symptoms of schizophrenia
- has good face validity
- however they explain the positive symptoms quite well
they fail to explain the negative symptoms
- cognitive models such as Frith and
Hemsley's have provided a way of explaining
many if the symptoms of schizophrenia
- Link to biological explanations
- strength of model is the link to biological
explanations as there is good evidence to suggest
schizophrenia does have an organic cause
- Frith produced evidence to show that there
was reduced cerebral blood flow
- pathway between the pre-frontal cortex and
the hippocampus during certain cognitive
tasks supporting this idea
- strength of model is the link to biological
explanations as there is good evidence to suggest
schizophrenia does have an organic cause
- Berger evidence for DBT
- found that schizophrenics reported a higher level of double bind
statements from their mothers than non-schizophrenics
- however not reliable as you are relying on patient's memories and
their memory could be effected by their illness
- other research has not supported Berger's
findings making them unreliable
- found that schizophrenics reported a higher level of double bind
statements from their mothers than non-schizophrenics
- Expressed emotion support
- has been universal support for the EE theory
- it is unclear whether the EE is a cause of schizophrenia or whether
it is a result of having a psychotic person in your family
- however one significant outcome is that it
has led to effective therapies that have
reduced the relapse rates in schizophrenia
- has been universal support for the EE theory
- Reductionist and its advantages
- psychological explanations of schizophrenia can
be see as reductionist as they clearly cannot
explain all forms of schizophrenia
- does not take into account good evidence that
schizophrenics may have an biological cause
- could be argued that by focusing on the elements of
disordered thinking of family relationships psychological
explanations have led to the use of effective therapies
- combined with drug therapy they have enabled
patients to manage their symptoms more
successfully and increase the quality of their life
- psychological explanations of schizophrenia can
be see as reductionist as they clearly cannot
explain all forms of schizophrenia
- Diathesis stress model
- findings of concordance rates being between 38-61% for MZ twins suggest a genetic vulnerability
- but genetic theory cannot explain all schizophrenia
- better explanation if the disorder would be to take a
multi-disciplinary approach such as the diathesis stress model
- suggests you may inherit a genetic predisposition to develop the illness
- but will not go on to develop the disorder unless stressors in your environment act as a trigger
- but will not go on to develop the disorder unless stressors in your environment act as a trigger
- amongst other things this would explain why middle class people
living in a supportive family with a pleasant enjoyable job are less
likely than those who do not to be diagnosed with schizophrenia
- findings of concordance rates being between 38-61% for MZ twins suggest a genetic vulnerability
