Abstract
In the last few years there has been a move away from sole reliance on pharmacological treatments for clients with schizophrenia as the NICE guidelines recommend clients should be offered cognitive behaviour therapy (CBT). Research designs have used randomised control trials (RCTs) to investigate the evidence base for CBT. This review explores the evidence from RCTs of CBT in reducing positive symptoms of schizophrenia, when administered early or later on in the disease course. Conclusions consider the limitations of studies, implications for clinical practice and suggest further research.
