My research involves the application of psychological principles to the understanding and treatment of psychosis, and attempts to determine how far we can ‘explain the unexplainable’ using normal psychosocial processes. My approach to the understanding and treatment of psychosis involves a strong emphasis on normalising theory, and integrates this with a programme of innovative clinical and experimental research.

My main research interests are the cognitive theory and therapy of psychosis, early intervention and the prevention of psychosis, developmental approaches to understanding psychosis (especially focusing on the relationship between early experience, trauma and psychosis) and the facilitation of user-led research. My programme focuses on these areas and involves collaborations with several different groups, including service users who are employed within my team as user-led researchers.


Tony Morrison is a Professor of Clinical Psychology at the University of Manchester and is also Associate Director for Early Intervention at Greater Manchester West Mental Health Foundation Trust. He has published over 100 articles on cognitive therapy for psychosis and experimental studies of cognitive processes in psychosis, including an influential cognitive model of psychosis, and has conducted several treatment trials of cognitive therapy for psychosis and for people at high risk of psychosis. He has also published several treatment manuals. He has also conducted research examining the links between trauma and psychosis and has explored issues of patient choice and the facilitation of user-led research into psychosis and mental health services. He is currently a member of 2 NICE guideline development groups (Psychosis in children and young people; Adult Schizophrenia and Psychosis: update) and is a member of the Department of Health Expert Reference Group for development of a competency framework for CBT for psychosis.  He is director of the Psychosis Research Unit at Greater Manchester West Mental Health Foundation Trust (see for more information).
