A02 psychological explanations of schizophrenia Flashcards
What are the 2 evaluations?
Psychological factor
Sociocultural factors
What are the 2 section so psychological factors?
Psychodynamic
Cognitive
Who support psychodynamic approach
Fromm reichmann
What did fromm reichmann say
Said psychophrenogenic mum’s are an important contributory in in schizo dev
What is the problem with fromm reichmann
There is no research evidence to support such a claim.
He’s a psychoanalyst
Who else supported view that family patterns may be cause of disorder in psychodynamic explanations
Oltmanns et al
What did oltmanns et al find
Parents of schizo patients behave differently to parents of non schizo patients
What is the problem with oltmanns study
Parents behaviour could be a cobs equine if their children’s disorder rather than a cause. It’s just a correlation no cause proven
Who supported the cognitive explanation
Lindenberg et al
What did lindenberg et al do and find
Found a link between excess dopamine in the prefrontal cortex and working memory
Conclusion of cognitive explanations
Research suggests there’s evidence for a physical basis for the cognitive deficits associated with schizo
What is the problem with lindenberg study
Correlational therefore doesn’t prove causation
What are the sections for sociocultural factors
Life events and schizophrenia Family rels Double blind theory Expressed emotion Labelling theory
Who evaluated life events
Os et al
Support or against life events in general?
2 against
What did os et al find and do
Reported no link between stressful life events and dev if schizo
Prospective study found lower likelihood of relapse in patients who has a major life event
What is the problem or second evaluation for studies on life events effects on schizo
They’re correlation studies so can’t prove causation
Dev of disorder could be a cause of the life events
Who evaluated family rels
Tienari et al
What did tienari et al find
Adopted children who had a schizo biological parent more likely to Dev schizo than kids with non schizo biological parent
Difference only emerged in disturbed adopted families
Conclusion of family rels
Family rels are important for explanation of schizo and are relevant but environmental conditions also apply
Who supported the double blind theory
Berger
What did berger find
Schizos reported a higher recall of double blind statements by their mum’s than no schizos
Who disagreed with the double blind theory
Liem
Hall and levin
What did liem do and find
Measure patterns of parental communication between families with schizo and no schizo members
Found no difference
What did hall and Kevin find and do
Meta analysis
No difference in patterns of communication between families with and without a schizo member
Conclusion for double blind theory
Some support that family rels may lead to schizo but many studies have dissapointed this
What’s the problem with bergers study
Not reliable because it’s based on memory of schizos which may be affected by their disorder
What’s the problem with the EE theory
Whether it’s a cause or effect of schizo
An advantage cz of the EE theory
Real world application, therapy used to reduce levels of EE in families
Who evaluated EE theory and EE therapy
Hogarty et al
What did hogarty et al find
Reducation of EE therapy could reduce relapse rates
Conclusion of EE
Recieved quite a lot of support
Could be an explanation for schizo
But not sure whether it’s a cause or effect of schizo
Which 2 people tested the labelling theory
Scheff
Rosenhan
What did scheff do and find
Meta analysis
13 studies consistent with the their, 5 inconsistent
Therfore theory supported by evidence
What did Rosenhan do and find
Page 165
Once the label of schizo is applied, the diagnosis continued to influence the behaviour of staff toward the patient
Conclusion of labelling theory
There is a lot of support for it. Evidence supports it
