psychological explanations and therapies Flashcards
(39 cards)
psychological explanations
- family dysfunction
- cognitive explanations
family dysfunction
abnormal processes within a family
- poor communication, cold parenting and high levels of expressed emotion
- risk factors for the development and maintenance of SZ
types of family dysfunction
- schizophrenogenic mother
- double-bind theory
- expressed emotion
what is a schizophrenogenic mother
the schizophrenogenic mother is cold, rejecting and controlling towards her family/ children
- proposed by Fromm-Reichman
- psychodynamic explanation based on client reviews of childhood
how does the schizophrenogenic mother cause SZ
- creates a family climate of tension and secrecy
- leads to distrust that later develops into paranoid delusions and ultimately SZ
what is double-bind theory
a situation where the child always receives mixed signals and are unable to comment on the unfairness or seek clarification
- emphasises the role of familial communication
- proposed by Bateson
how does double-bind theory lead to schizophrenia
- when they get smth wrong, they are punished by withdrawal of love
- leaves them w an understanding that the world is confusing and dangerous
- reflected by symptoms like disorganised thinking and paranoid delusions
> clear that this is not the only factor, just a risk factor
what is expressed emotion
the level of emotion, particularly negative, expressed towards someone w SZ by their carers
elements of expressed emotion
- verbal criticism of them, occasional accompany of violence
- hostility towards them, anger and rejection
- emotional over-involvement, needless self-sacrifice
how does expressed emotion cause schizophrenia
high levels of expressed emotion are a serious source of stress
- explanation for relapse in ppl w SZ
- suggested that the source of the stress can trigger the onset of SZ in someone who is already vulnerable, maybe bc of genetic makeup
research investigating family dysfunction
Sojit
- observed parents of SZC’s interact w them and compared to control
- support double-bind, parents of SZCs were more likely to send mixed messages
supporting evaluation of family dysfunction
P - there is support for family dysfunction as a risk factor
E - Read et al found 69% of women and 59% of men w SZ reported childhood physical/ sexual abuse
- Berry et al, adults who had insecure attachment to PCG more likely to have SZ
E - traumatic childhood may disrupt brain development, impair emotional regulation
CA - most use retrospective recall (Tienari), SZ symptoms could distort memories, reduces validity
L - family dysfunction is associated w SZ but more rigorous research needed
limiting evaluation for family dysfunction
P - weak evidence for family based explanations
E - no support for the importance of SZC mother or double-bind theory, just based on clinical observations, lacks scientific rigour
E - theories emerged from psychoanalytic approaches but fail to account for biological/ genetic factors
CA - family dysfunction does correlate w SZ, but theories over-simplify causation
L - modern psychiatry emphasises multifactorial models, interactionist, over out-dated theories
issues and debate link for family dysfunction
schizophrenogenic mother shows acute gender bias (alpha bias)
- suggests mothers play a key destructive role in onset of SZ in a child
cognitive explanations
dysfunctional thought processing
what is dysfunctional thought processing
refers to the way in which a person w SZ understands, perceives and interprets the world and others
how does dysfunctional thought processing cause schizophrenia
SZC may be unable to distinguish between the inner voice and what they perceive to be a voice actually speaking to them
- suggested by Frith
types of dysfunctional thought processing
- metarepresentation
- central control
metarepresentation
the cognitive ability to reflect on thoughts and behaviour
- allows insight into our own intentions and goals
- dysfunction would disrupt the ability to know our actions are carried out by ourself and not others
- explains delusions and hallucinations
central control
SZCs lack cognitive ability to suppress automatic responses
- disorganised speech and thought disorder could be a result of this
- SZC experience delayed speech bc words trigger associations and they can’t suppress this automatic responses
supporting evaluation of cognitive explanations
P - strong evidence for dysfunctional thought processing
E - Stirling et al, compared 30 SZCs to 18 control in the time it took them to read a list of colour written in another colour (eg. green but in red font, answer is red)
- SZC group took twice as long as control
E - aligns w Friths theory of central control that SZCs have difficulty in suppressing automatic processes
CA - does not tell us about origins of SZ
- explains proximal causes but not distal
L - still provides understanding, may need more depth of research
psychological therapies
- CBT
- Family therapy
- Token economies
Cognitive Behaviour Therapy
method for treating mental disorders using cognitive and behavioural techniques
- eg. cognitive = challenging negative thoughts
CBT in schizophrenia
takes 5-20 sessions
- aim involves identifying irrational thoughts and trying to change them
- will not get rid of symptoms, only helps ppl cope better
