Patient Factors that Impact upon Cognitive Behavioural Therapy for Psychosis: Therapists' Perspectives.

Background: Randomized controlled trials have established that cognitive behavioural therapy (CBT) is effective in helping people with psychosis, though there is enormous variability in outcome. It is not clear what patient factors contribute to good outcomes. In fact, most studies considering client factors have excluded people with psychosis.

What do people with psychosis think caused their psychosis? A Q methodology study.

Background: A key component of cognitive therapy for psychosis is the development of a meaningful and shared formulation of the onset of the psychosis. Therapists bring an understanding of the development of psychotic symptoms based on theoretical models and try to marry these with the person's own experience and explanations. However, an important question is whether this understanding is compatible with the explanations held by the client.
