Numerous studies have shown that patients with psychosis are more likely to use illicit drugs than the general population, with cannabis being the most popular. There exists overwhelming evidence that cannabis use can contribute to the onset of schizophrenia and poor outcome in patients with established psychosis. Therefore, understanding why patients use(More)
BACKGROUND AND OBJECTIVES Acceptance and Commitment Therapy (ACT) is a contextual cognitive-behavioural approach with a developing evidence base for clinical and cost-effectiveness as an individually-delivered intervention to promote recovery from psychosis. ACT also lends itself to brief group delivery, potentially increasing access to therapy without(More)

In light of this, the Department of Health have set the physical health of people with mental health problems as a(More)
The outcome of first episode psychosis (FEP) is highly variable and difficult to predict. We studied prospectively the impact of poor insight and neuropsychological deficits on outcomes in a longitudinal cohort of 127 FEP patients. Participants were assessed on 5 domains of cognitive function and 2 domains of insight (clinical and cognitive). At 12 months,(More)
BACKGROUND Early cannabis use has consistently been associated with an increased risk for the later development of psychosis. Studies suggest that Conduct Disorder (CD) is more common amongst young people who later go on to develop psychosis. CD has been associated with greater and earlier cannabis use in general population samples. Based on this evidence,(More)

This study investigated the reasons for cannabis use in first-episode psychosis (FEP) and whether strength in their endorsement changed over time. METHODS FEP(More)
BACKGROUND The insight into psychosis can be assessed reliably by clinicians from interviews with patients. However, patients may retain implicit awareness of illness while lacking explicit awareness. SAMPLING AND METHODS In a sample of first-episode psychosis patients, we used a test of processing of mental illness-related and other negative words as a(More)
