psychological therapy for psychosis Flashcards
what is psychosis
loss of contact with reality
what psychiatric disorders does psychosis describe
Term used to describe the characterisic complaints of several psychiatric
disorders, most notably diagnoses in the schizophrenia-spectrum
(schizophrenia, schizo-afecive disorder, delusional disorder etc)
what does psychosis involve
It involves clusters of “symptoms” including positive symptoms (hallucinaions,
delusions etc) and negaive symptoms (flat affect, avolition etc)
what are positive symptoms
Present in people who have psychosis but are assumed to be absent in people who do not have psychosis
what are negative symptoms
Negative symptoms are experiences that are absent or reduced in people who have psychosis and are assumed to be present in those who do not have psychosis
are the symptoms in psychosis common in the general population
In the general populaion these symptoms are not rare and are generally
unproblematic, but in some individuals they can lead to considerable distress
and reduction in functioning
Quite common - don’t need any mental health support
Minority of individuals in which these experiences can be come highly distressing and debilitating and can impact the functioning and therefore might benefit from some form of additional support
what are the factors involved in development and maintenance of psychosis
Biological but also psychosocial factors are involved – despite this service
users have mostly receive only biological treatments (anipsychotics)
when did psychological therapies for psychosis become accepted
Psychological therapies for psychosis did not become widely
invesigated or accepted as potenially useful treatments unil the
1990s
why was there a delay in developing talking treatments for psychosis
• Psychosis was seen as fundamentally diferent from neurosis (presentations like anxiety and depressions seen as more amenable to psychological interventions)
• Symptoms not seen as understandable in psychological terms (e.g. Jaspers)
• Lack of therapeuic opimism in the treatment of “schizophrenia”.
– Poor results from early trials of psychotherapy.
early days primarily focused on psychodynamic or psychoanalytic approaches
– neuroleptics seen as only viable treatment option
Outdated term for what we would call today antipsychotic medication were seen as the only viable option for supporting people with this psychiatric diagnosis of schizophrenia and related psychotic disorders
name the 5 psychological therapies for psychosis
- Rogerian Counselling
- Psychoanalyic therapies
- Cogniive Behaviour Therapy
- Family therapy
- Intervenions to reduce substance misuse

what is CBT
see slide 9
activating event (internal or external)
thoughts (negaive automaic thoughts, thought distorions, appraisals etc)
behaviours
feelings/emotions
what is an activating event (internal and external)
Events can be both external so actual experiences that they will encounter ver the course of a daily life or also internal experiences so e.g. particular memory or perceptual experience
what is CBT for psychosis
Cogniive Behaviour for Psychosis (CBTp) is the applicaion (and adaptaion) of
the same basic principles to understand the distress and impairment caused
by psychoic experiences
how does NICE define CBTp
The National Insitute of for Health and Care Excellence (NICE, 2014) defines
CBTp as a psychological intervenion where service users:
o Establish links between, thoughts, beliefs, percepions and feelings in
relation to their current or past symptoms and/or functioning
o Re-evaluate their beliefs, percepions and reasoning relaing to target
symptoms
o CBTp should involve development alternaive ways of coping with the
target symptoms, and/or reducion of distress, and/or improvement of
funcioning.
what is NICE
The Naional Insitute of for Health and Care Excellence (NICE, 2014)
what are the basic CBTp strategies
• Formulating (making sense)
• Normalising psychosis
• Improving coping
• Strategies to change unhelpful thoughts, beliefs and appraisals
- That they have in relation to their difficulties and that perhaps are involved in the maintenance of their difficulties in keeping the problem over time
what is formulating?
Typically when an early goal for therapy is agreed in the early session of the intervention so for example which specific problem the client would like to improve and the therapist will carry out a detailed assessment to identify thoughts feelings behaviours etc that are linked to the presenting difficulties that the clients wants to change then the therapist will work gradually with the client to help them understand how these factors thoughts feelings behaviours interact with each other and maintain these problems in the present, ultimately this enables to create an element of a shared understanding of how the problem is developed and how to resolve or improve it
how the therapist formulates psychotic experiences
After appropriate goals for therapy are identified (e.g. which problem/symptom to target), the therapist carries out an assessment to:
o Identify thoughts, feelings behaviours etc linked to the problem/symptom targeted
o Help the client to see how these interact to maintain the problem in the present
o Create a shared understanding of how the problem developed and what could be done to resolve it
It involves enabling the clients to understand in more detail how the difficulties came about and how they are maintained in the present using the general principle of cognitive behavioural theories for understanding that specific difficulties
what do therapists use in CBT to formulte difficulties
Often in CBT, therapists use well-established models to formulate difficulties (“templates”)
cognitive model of hallucinations state hallucinations are
In common with other cognitive models of mental health difficulties this model assumes that auditory hallucinations are not distressing and problematic in themselves the distress and impairment caused by these experiences is driven by how the person makes sense of these experiences
what does the cognitive model of hallucinations state triggers are
internal or external e.g. stress, sleep deprivation, isolation
cognitive model of hallucinations stages
triggers - auditory hallucinations - safety behaviours - misinterpretation of hallucinatory experience - mood and physiology
why do hallucinations cause distress according to the cognitive model of hallucinations
If a person interprets or misinterprets the hallucinatory experience in a catastrophic negative way they might experience negative arousal negative emotions nad distress which in truth might have an impact on the presence of hallucinations in themselves so the intense arousal of these interpretations might actually make the presence of the auditory hallucination more severe and frequent
Depending on how people interpret these hallucinatory experiences people will try to employ different safety behaviours so way of coping with these unwanted experiences some of which might actually paradoxically increase tree future severity or presence of hallucinatory experiences
negative appraisal of the experience
what will CBT do to help negative appraisals
change the appraisal so that the meaning making the person has employed to make sense of their voice is better
better ways of coping
when does normalisation happen
normally happens towards the early stages
what is formulating in CBTp
making sene of psychotic experiences
why do we need to normalise psychosis as part of CBTp
The rational for normalisation of psychosis is that essentially people when they come to therapy not only are reporting distressing voices unusual beliefs but often come with the whole baggage of notion of what it means to be psychotic schizophrenic and the dangers associated with that
People will often have beliefs that their brain is defective and will never get better and things will only get worse etc
what does normalising psychosis mean?
- Challenging the (internalised) stigma of psychosis
- Correcting common misconceptions about psychosis, its causes and its consequences
- Provision of more accurate information
- Promotion of more balanced views about psychosis
are people with psychosis dangerous
There is no evidence that people with psychosis are more dangerous or violent than the general populaion. Violence in psychosis is explained mostly by other factors (substance misuse, pre-exising history of violence, criminal involvement
etc) (acute confusion etc.)
• People are more likely to be withdrawn or preoccupied with their own problems
• People with psychosis are much more likely to be the vicim of violence rather than the perpetrator (e.g. Maniglio 2009)
is psychosis for life?
- Psychosis is not necessarily for ever.
- Many people have a single episode that never occurs again (about 30%).
- Some people experience more than one episode even ater long periods of being symptom-free (about 30%).
- A minority of people have persistent ongoing symptoms (< 25%).
Recovery and remission from psychotic experiences is the norm rather than the exception
are people with psychosis unable to work?
• There might be imes when a person’s distress is such that it interferes with their
ability to funcion but this is not necessarily so.
• Many people who have experienced or currently experience symptoms of
psychosis are able to work, have relationships and manage to function in their life.
does psychosis always cause distress and do people always need treatment?
• Many people experience unusual beliefs or hear voices, but are not distressed by
these experiences (e.g. van Os et al., 2000)
• Many people make sense of their experiences in a way they can ind helpful
(e.g. psychic experiences/ telepathy, reincarnaion, shamanism etc.).
• In some cultures, psychoic symptoms are viewed posiively (e.g. Al-Issa, 1997).
May find ways of interpretations experiences in a helpful way so e.g. reframe as manifestation of some kind of ability they might have such as having psychic experiences for example
Normalisation of psychosis - expose people to this different kind of understanding of psychotic experiences
Encourage understanding that the distress they experiences is related to the way theyre making sense of the experience - different ways of framing this experience can be more or less distressing for people
what can psychotic experience be brought about by?
Psychoic experiences can be brought about by many experiences such as:
– Lack of sleep
– Sensory deprivaion
– Substances or aciviies creaing altered states of consciousness
– Stressful events (hostage situations,combat stress and other life threatening situations etc)
– Bereavement
– Trauma (bullying, abuse, violence in home, run away from home, placed in care as achild etc)
– brain disease
what is improving coping
Important element of CBT for psychosis is the provision of additional and helpful ways for coping with psychotic experience
what do coping strategy enhancements consist of?
• The aim is to (1) increase the repertoire of coping strategies the client can use when facing distressing symptoms, (2) provide some respite, (3) encourage a greater sense of control
o Reviewing the strategies the client already uses to cope with psychoic experiences, how often/when they are used and how effecive they are
o Encourage the client to experiment with new coping strategies
name some of the coping strategies based on our understanding of symptoms of psychosis (e.g. relationship between inner speech and auditory verbal hallucinaions)
-humming
-reading
-singing
-reduce subvocalisation (filling our mouth with water)
coping starategies that interfere with the generation of inner speech has been shown to be effective in reducing the intensity of voices)
what are the coping strategies based on responding diferently to symptoms
o Acing asserively / Dismiss the voice
o “Making an appointment “ with the voices
o Respond raionally to the voice content
what are the coping strategies to reduce arousal and distress
o Listen to soothing music
o Mindfulness meditaion
o Relaxaion exercises
o Use posiive imagery / self-statements etc…
how to challenge unhelpful beliefs/appraisals of psychotic experiences
Use Socraic quesioning in session
Ask paricipants to keep a log of recent voice hearing experiences
Evidence / counterevidence analysis
Behavioral experiment
what is a behavioural experiement
Ask client to test out maladaptive belief they have - stop all safety behaviours and see if they really lose control - following a risk assessment. - vast majority of circumstances people just have belief that might happen and the chance they carry out violent behaviour because of their psychotic experiences is actually minimal they are distressed because they are concerned about it
is cbt for psychosis effective - randomised controlled trials
Over 50 RCTs have examined the ecacy of CBT in people with psychosis, with posiive indings across most “stages” of psychosis:
First episode psychosis / early psychosis (e.g. Tarrier et al. 2004)
Acute psychosis (e.g. Lewis et al., 2002; Garety et al., 2008)
People at risk of relapse (e.g. Gumley et al., 2003)
Treatment resistant psychosis (e.g. Durham et al., 2003; Valmaggia et al., 2005; Turkington et al., 2008)
Groups (Chadwick et al., 2000; Johns et al, 2002)
is cbt effective - meta-analyses
These meta-analyses have shown that CBT can improve psychoic symptoms, especially in the case of posiive symptoms
can CBTp be effective without Neuroleptics
CBTp can be efecive on its own, even in individuals that are not taking anipsychoic medicaion
what does NICE reccomend in terms of CBT for treating psychosis
NICE (2014) recommends that CBT should be ofered as a first line treatment across the coninuum of psychosis
• People at clinical high risk (prodrome)
• First episode psychosis
• “Chronic psychosis” to promote recovery
what does NICE reccomend in relation to trauma
NICE also recommends that all people with psychosis should be assessed for trauma and post-traumaic stressed and offered trauma-focused psychological therapies (including CBT) when appropriate (BUT recommended more research into their safety and efficacy in this specific populaion)
Strong link between trauma and life adversities and the risk of developing psychosis - NICE recognise this - CBT could be applied - emotional and psychological consequences or trauma
