Brief Summary
The study is a pilot study of Cognitive therapy for people with psychosis who have distressing visual hallucinations. The aim is to evaluate whether this is an acceptable, feasible and effective treatment. This is a pilot study and there is no randomisation to either CBT or treatment as usual (TAU). If a participant is allocated to the cognitive therapy plus TAU condition then the participant will meet with a therapist on initially a weekly basis and receive up to 8 sessions of CBT over a 2 month period. The participant will also have regular assessments conducted by a researcher who is independent to the treatment group. It is predicted that those people receiving CBT will improve on measures of symptoms, and particularly for measures of visual hallucinations.

Outcome Measures
Primary Outcomes (1)
Change from baseline in distress of visual hallucinations as assessed by the Psychotic symptoms rating scale for hallucinations (PSYRATS).
The PSYRATS measures distress, conviction and preoccupation and impact of life of symptoms such as voices or delusions. It has been adapted to be relevant to visual hallucinations.
change pre to post intervention which will be on average 3 months
Secondary Outcomes (2)
Change from baseline on measure of depression (Beck Depression Inventory)
Baseline and at three months
Change from baseline on measure of symptoms of psychosis as measured by he Schizophrenia Change Scale (SCS). The SCS is a subscale of the Comprehensive Psychopathological Rating Scale (CPRS), (Montgomery, Taylor, & Montgomery, 1978)
baseline and at three months
Interventions
Eight to ten sessions of manualised CBT for distressing visual hallucinations based on existing treatment manuals (ie. Kingdon \& Turkington, 2004, Morrison et al., 2005), delivered over 8 to 12 weeks by CBT therapists. Subjects will continue to receive treatment as usual throughout the therapy period and will receive appropriate prescription of medication if requested or clinically indicated.
Eligibility Criteria
People in Early Intervention in Psychosis services who are reporting distressing visual hallucinations in the past month.
You may qualify if:
- Meet entry criteria for Early Intervention in Psychosis (EIP) services
- Distressing visual hallucinations
- Age 18-38 years (the usual upper range of the EIP services)
You may not qualify if:
- Organic brain disease including dementia, epileptic psychosis, head injury (may be alternative cause of symptoms, or impair cognitive function and ability to do CBT)
- Primary diagnosis of drug or alcohol misuse (as above)
- Impaired intellect severe enough to interfere with ratings (as above)
- In-patient/acute psychiatric care needed at baseline assessment (patients must be well enough to engage in out-patient CBT)
- Previous CBT for psychosis (those previously exposed to the CBT model may be more likely to respond to CBT)
