Schizophrenia-therapies-psychological Flashcards
CBT- URAP
developed to treat depression due to effectiveness in treating negative symptoms
but also routinely used to treat psychotic symptoms too
USE: NICE recommend it to all patients in combo with drug treatments
RATIONALE/ AIM: sz caused or at least maintained by the beliefs patients have about tier experiences.
deal with symptoms by changing beliefs and leading to less catastrophic symptoms
aim to identify these flaws in rationality which contribute to symptoms and change them
PROCESSES: agenda set between therapist and patient
more flexible than normal CBT
generally 12-20 sessions- reflecting complexity and diversity of disorders
Cognitive element
make patient aware of their cognitions and its role and how they impact their functioning
meta-cognition- thinking about thoughts
question challenge and change beleifs
behavioural element
test patients beliefs against reality
achieved through experimentation and role play and homework
allow patients to become aware of irrationality of beliefs
but try to treat them as a rational person as much as possible
example of CBT
Ellis’s rational emotive behavioural therapy
ABC model is used to allow the patient to organise their confusing experiences
how activation events beliefs and consequences interact
eg
patient pinpoints an activating event and subsequent consequence e.g hearing voices causing looniness/depression, the patient may say the voices control their life, so the therapist tries to get the patient to understand that the beliefs they have are illogical by testing the evidence for and against maladaptive beliefs
e.g pinpoint behaviours that patient has engaged in which they have had full control over
other techniques within CBT normalisation
normalisation techniques: being empathetic to the patients irrational beliefs and as much as possible get them to understand that they’re normal but not entirely accurate for example a patient thinking that the police are racist towards him, when they’re just racist generally, enabling them to understand that the delusional fear is somewhat founded and normal. this doesn’t negate their beliefs, it allow them to maintain them but in a more realistic form.
other techniques within CBT decatasrophising
decatastrophising
informing the sz patient that lots of people have unusual experiences in circumstances e.g. stressful events, torture, hunger, thirst etc) reducing the anxiety they have around it and the sense of isolation, so the psychotic symptoms are put on a continuum with normal experiences. the possibility of recovery then feels less distant
developing trust through non judgemental approach
gentle questioning allows the patient to recognise potentially illogical deductions and conclusions
if your voices are coming from the radiator- why can’t anyone else hear them?
testing evidence for and against maldadptive beliefs
effectiveness of CBT- research design
some trials conducted are repeated measures pre-post treatment trials-
less useful than independent design- comparing CBT with a control group or another treatment
because pre-post allows for spontaneous remission (natural regression of symptoms) cannot truthfully detect whether the change is natural or due to the treatment
issues in evaluating CBT
only some trials are RCT
in most trials the majority of patients will be on medication as well
would be immoral to justify use of only CBT for some patients as there’s strong evidence that the illness is on a biological premise- could be detrimental to their health
so theres no other way of doing it
but this makes it more difficult to separate the effects of the drugs from that of the CBT
effectiveness of CBT
Rector and BEck AND Gould et al
found CBT reduces positive symptoms but effects are smaller in proper RCT rather than pre-post treatment studies
effectiveness of CBT wakes et al
found effect size of 0.4 (weak-moderate) between CBT and no treatment
but only an overall effect size of 0.22 in quality trials (those with blinding) which is weak
effectiveness of CBT jones et al
meta anlaysis (cochrane review)
review of RCTs found that CBT was no more effective than other psychological therapies on any criteria (functioning, relapse etc).
this is despite NICE recommending it as the front line psyholoigcal treatment for schizophrenia.
although overall number of people leaving the study early was low compared to drug trials— meaning talking therapies may be better at retaining people with sZ in treatment.
the review also suggested there may be some longer term advantage in CBT for dealing with emotions and distressing feelings
Phoroah et al’s cohcrane review found the same (no difference between CBT and other talking therapies)
concluding thoughts on effectiveness of cBT
the original enthusiasm for CBT may have been based on inadequate trials including some weak blinding and in the case of NICE the relative cost of CBT (i.e. training therapists) compared to other psychological treatments.
the positive view of CBT is often based on individual trials and sometimes older meta-analyses- jones et al’s cochrane review is more recent and less positive-
which may be particularly reliable as a cochrane review, so should be less biased than reviews conducted by those with their professional reputation as proponents ofCBT at risk
trials that have shown cbt to be very effective, alarm us to the fact that they have methodooligcal flaws- e.g wykes points out that ‘trials make no attempt to mask the group allocation are likely to have inflated effect sizes.’ so when they know which group has the treatment they favour the cbt condition
CBT appropriateness
low cost and speed - good for NHS (tax payer consideration)
no side effects! compared to drug treatments!
fewer issues on dependence on therapist because the there isn’t a close relationship between CBT and patient it’s more teaching to improve (collaborative) rather than comforting to encourage independence of patient so an advantage over other talking therapies e.g psychoanalysis
patients tend to like CBT
trials tend to have lower attrition than drug trials and other talking therapies
big advantage! even if it is no more effective than other talking therapies it is better that patients stay in therapy and get these benefits if they would just drop out of psychoanalysis for example
issues related to effectiveness of CBT
if the meta analyses are right that CBT is equally as effective as other talking therapies then maybe it should be that others are available not he NHS
but then again it;s the cost that has to be considered which justifies the use of cBT over anything else
