What I will talk about
• What is CBT for psychosis and are there different types of CBT?
• Do we need different therapies for different phases of early psychosis?
• The case for the use of specific psychological interventions and current research

Young people with early psychosis
• Have episodes of severe disturbances in thought, emotion and behaviour (delusions and hallucinations)
• Most recover from such episodes but some remain socially disabled and depressed
• Some are at high risk of developing chronic syndromes with need for repeated hospitalisation and high service use
• need specialised multidisciplinary care due to the complexity of their problems and “difficult to treat” presentations

Ben came into contact with mental health services because his mother was worried about him. He had recently left home to live in a bed-sit. He had become increasingly disorganized. His flat walls were covered in paintings and he was pre-occupied with drawing, not sleeping and not eating or looking after himself. He talked in a bizarre way about God, good and evil and about how his task was to save the world. He said that painting helped him to make sense of things. He was clearly listening to voices. He said these were God and the Devil talking to him. He said he didn't need any help.

A psychological perspective
Psychosis as a life crisis which sets a series of adaptive demands for the individual
![Page 7: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/7.jpg)
Making sense of psychosis: formulating psychotic problems
• Normal models of adaptation to stress
• Vulnerability stress models
• Cognitive models of psychotic symptoms
![Page 8: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/8.jpg)
The evolution of voices and delusional beliefs
![Page 9: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/9.jpg)
The cognitive model of psychosis and its clinical implications
• The cognitive perspective suggests that psychosis is more amenable to understanding than is commonly believed
• Helping people understand the nature of their personal vulnerability to psychosis is a core process of cognitive therapy
• Cognitive therapy involves helping people to become aware of errors in the way they think about psychotic experience to compensate for these
• The aim is to help the person construct a less distressing and more adaptive way of understanding their predicament
![Page 10: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/10.jpg)
Cognitive Behaviour Therapy
• Works from the patient’s point of view• Is collaborative• Builds up strengths (does not strip away defences) • Builds on good basic psychotherapeutic skills (warmth,
empathy, concern)• Central task is making sense of and explaining psychosis • Process of therapy, strategy and use of techniques is
guided by individualised assessment and formulation
![Page 11: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/11.jpg)
The six stages of Cognitive Behaviour Therapy for Psychosis
Engagement and assessment
Promoting self regulation of psychotic symptoms
Developing a shared model of psychosis
Addressing delusions and beliefs about voices
Addressing dysfunctional assumptions about self and others
Addressing social disability and risk of relapse
![Page 12: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/12.jpg)
Adaptations in working with people with persistent voices and delusions
• People with high conviction in delusions typically lack of a shared rationale with therapists
• People with voices typically do not regard them as symptoms
• Overcoming dissonance and working from the patients perspective is key
• Flexibility, individualisation, and careful attention to engagement is required

CBT for psychosis?
![Page 18: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/18.jpg)
CBT for psychosis: a better analogy
![Page 19: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/19.jpg)
Does CBT work?Published trials with people with treatment
resistant psychosis
Effect size
• London-East Anglia trial: CBT versus case management 0.86 (Kuipers, Fowler, Garety et al, Brit. J Psychiatry,1997; 1998) (9 months individually formulated CBT) 29% improvement in BPRS symptom ratings 65% CBT versus 17% CM made 25% improvement in symptoms • Manchester trial: CBT versus supportive counselling 0.57 (Tarrier et al; BMJ 1998; Brit. J Psychiatry,1999) (8 weeks, CBT package techniques) • Wellcome trial: CBT versus befriending 1.18 (Sensky, Turkington, Kingdom et al, Arch.Gen, Psych 2000)
(9 months individually formulated CBT) .

Systematic review of trials of CBT (odds ratio)Participants receiving CBT have a 22% greater chance of
making a 50% improvement in mental state at post treatment than alternative condition

RCT of CBT to prevent relapse:The PRP project
Sample: People with psychosis presenting with second or subsequent acute psychotic relapse in 5 centres in London, Essex and Norfolk
Design 1) Alone: CBT vs TAU n=280 2) Family CBT vs FI vs TAU n=90 9 months treatment, 2 year f/uMeasures: 1) relapse, readmission, cost 2) symptoms, social functioning, quality of life 3) process measures
Recruitment at 11/03 n=212
![Page 22: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/22.jpg)
CBT in relapse prevention (Gumley et al, 2003)
• Targeted at high risk of relapse groups• Therapy initiated at recovery: traditional CBT approach
(psychoeducation, warning signs, management of relapse, fear of relapse)
• Booster sessions at incipient relapse• At 12-months, 11 (15.3%) CBT group 19 (26.4%) TAU admitted• 13 (18.1%) CBT relapsed compared to 25 (34.7%) in TAU • CBT group showed greater improvement in negative symptoms (mean
difference CBT - TAU in change from baseline at 12 months -1.73, p = 0.035, 95% CI –3.33, -0.13), global psychopathology (-4.10, p = 0.0012, 95% CI –6.55, -1.65), performance of independent functions (2.70, p = 0.027, 95% CI 0.32, 5.08) and prosocial activities (3.99, p =0.0072, 95% CI 1.10, 6.88).
• (Rector and Beck, 2003, Schiz, Res., Sensky et al, 2001; also show benefits in negative symptoms, gen psychopathology from traditional CBT approach)
![Page 23: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/23.jpg)
Conclusions
• There is strong evidence for effects of CBT on symptom reduction and distress with people who have distressing chronic treatment resistant psychotic symptoms
• There are promising indications of evidence for CBT in preventing relapse/readmission the PRP study will provide a definitive indication
![Page 24: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/24.jpg)
What interventions for what stage of early psychosis ?
• At risk mental states - anomalous experiences. odd beliefs, distress
• First Episode - severe disturbances of thought, behaviour and affect
• Recovery - amotivation, depression, withdrawal• First admission- psychosis and the effects
hospitalisation• Second episode and relapse• Delayed recovery/ongoing psychosis-treatment
resistant symptoms, relapse, chronic emotional disturbance and social disability
![Page 25: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/25.jpg)
The evidence basis for specific psychosocial interventions at different stages
• At Risk Mental States: 2 preliminary trials of CBT; further trials underway/planned
• First Episode: equivocal evidence for CBT-large trial (SoCRATES) suggests support = CBT
• Social recovery and depression: No trials-need for a new treatment (evidence for supported employment (IPS) in chronic cases, preliminary evidence for CBT on depression/negative symptoms)
• Relapse: good preliminary evidence: PRP trial will be definitive
• Delayed recovery and treatment resistant psychosis: evidence is strong, NICE suggest CBT should be provided
![Page 26: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/26.jpg)
Problems in At Risk Mental States
“Something odd is going on” “I feel strange”
“I feel different from others” “I sense evil around” • Anomalous experiences• Search for meaning and delusional formation• Ongoing psychological difficulties• Engagement problems • Drug abuse
![Page 27: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/27.jpg)
Therapy targets for early stage psychosis
• Establishing a relationship• Providing a framework for understanding
anomalies of experience• Decatastrophising and normalising• assisting the search for meaning• managing ongoing psychological problems
(anxiety/depression)• Promoting adaptive behaviour by behave expts • Structured short term therapy akin to
traditional CBT for anxiety/depression
![Page 28: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/28.jpg)
Problems at the recovery stage
“I still feel ill” “Something’s wrong with me” “I’m not quite right” “I feel different to before”
“I'm fine” “I'm ok” “don’t want help” “just want to get on with my life”
• Amotivation• depression• social withdrawal and social disability• anomalies of experience and beliefs
• NB: These problems are often missed in people who may be described as doing ok
![Page 29: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/29.jpg)

The Issues
Suicide occurs in 10-15% of cases;mainly
in first 5 years . Parasuicidal risk averages 20-30% Rate of post psychotic depression in first-episodes: 25%-80%
![Page 31: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/31.jpg)
Depression as a psychological reaction to psychosis and trauma: recent
psychological studies• Depression in early psychosis is associated with increased
loss shame humiliation and entrapment and lower social comparison (Iqbal et al, 2001; Plaistow and Fowler, submitted)
• Depression, negative symptoms and social disability are strongly associated with each other at the recovery stage and also with the degree to which individuals can see themselves in meaningful roles and goals in the future (Day and Fowler, Submitted)
• Depression is associated with reporting intrusive memories and avoidance of traumatic events (Fowler et al, In Press)
![Page 32: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/32.jpg)
So, what does all this mean for early intervention??
• Amongst cases apparently symptomatically stable (in between psychotic episodes)
• we need to monitor and target depression and hopelessness, and prevent appraisals of loss shame and entrapment
• We need to carefully target patterns of social avoidance which may emerge initially as protective
![Page 33: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/33.jpg)
Individual placement and support
• Vocational workers focussing on social recovery who have links to employers and knowledge of employment issues work alongside case managers as part of an assertive outreach team (Bond)
• Hartford study (Mueser et al, J.Cons Clin Psychol, In Press) IPS (373 days employed) vs 176 days standard treatment
• Crowther et al BMJ, 2001 systematic review
![Page 34: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/34.jpg)
Developing Individual Placement and Support
• Effects are on low paid service sector employment which is transitive
• Needs attention to meaningful goals and career pathways
• At present suitable for people who are fully recovered ready to work
• Can psychological therapy prepare more people for IPS?
• Factors involved include hopelessness, amotivation, cognitive deficits and depression
![Page 35: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/35.jpg)
The case for Social Recovery oriented CBT in early psychosis
• We need a new treatment which offers social opportunities while addressing psychological problems including depression, social avoidance
• Ideally this will combine best practice in vocational interventions (IPS) with structured psychological interventions (CBT)
• This treatment is in the early stages of development
![Page 36: Psychological therapy in early psychosis David Fowler Reader in Clinical Psychology, UEA Consultant Clinical Psychologist, NMHCT.](https://reader036.fdocuments.us/reader036/viewer/2022062712/56649c745503460f94926f5e/html5/thumbnails/36.jpg)
Key psychosocial interventions in Early intervention in psychosis to include:
• Support through the acute phase in least restrictive supportive therapeutic settings
• CBT for delayed recovery: treatment resistant psychosis and relapse
• Social recovery intervention: Case managers providing an assertive vocational recovery programme addressing depression and anxiety in collaboration with supported employment/education/leisure.
• User and family support and psyched groups• Family work
• With protocol driven psychopharmacology

And it should all lead to.....
• a much better social and symptomatic long term outcome for young people with severe mental illness
