Plain English Summary
Background and study aims
Schizophrenia and related psychoses often make it harder for sufferers to concentrate, remember things like appointments, change the way they think about things when they need to (flexibility) and do several things at the same time. This might also make it harder for people to take part in talking therapies like Cognitive-behavioural therapy (CBT). The researchers running this study hope to use Cognitive Remediation (CR) to help people get more out of CBT. CR is a way of training the brain to deal with difficulty in concentration, memory and so on, based on practicing puzzles and other tasks. Other studies have shown it can work to improve these things but have not used it before CBT. This study will investigate whetherthe use of a course of Cognitive Remediation (CR) prior to participation in CBT will improve the effectiveness of the CBT. CR is a form of brain-training using a programme of mental puzzles and other tasks which is known to be effective in improving cognitive capacities.
Who can participate?
Patients aged between 16-35 with a mental health disorder that take cannabis.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 are given 40 hours of CR over a 12 week period before CBT. Those in group 2 are given 40 hours of social support over a 12 week period before CBT. All participants are given CBT for a period of between 12 and 30 weeks. Each participant is assessed at the start of the study using a wide range of measures including the severity of their symptoms and their cognitive capacities (how well they think). They are assessed again after they have completed CR or social support and every 6 weeks for another 30 weeks after they start their CBT.

Study information
Scientific title
HELPER Programme (Substance Misuse) - A phase-specific psychological therapy for people with problematic cannabis use following a first episode of psychosis (ReCAP)
Acronym
HELPER (ReCAP)
Study hypothesis
We are conducting an exploratory trial to evaluate whether a psychological therapy following a first episode of psychosis is effective at reducing cannabis use when compared to usual care. This study will also investigate whether a brief intervention (4.5mths) is as effective as a longer one (9 months). This is a randomised controlled trial with 3 treatment groups, long-term treatment, short-term treatment, and treatment as usual.

Condition
Psychosis
Intervention
64 patients waiting for CBT after their first episode of schizophrenia, who agree to take part, will be randomly selected either for CR or support from a Support Time and Recovery Worker. They will see either the therapist for 40 hrs or the support worker for the same amount of time over 3 months. After this both group will have CBT as part of normal NHS service, for 12 - 30 sessions. Participant's symptoms and neuropsychological skills will be assessed at recruitment and after 12 weeks by an assessor is blind to which group they are in. They will then have delusions and hallucinations reassessed for every 6 weeks for another 30 weeks, during CBT.
