Group members' work arguing for a psychosocial approach to mental health has been influential in both policy and public debates. This work has a long history in the group, with past members' producing seminal texts such as Mary Boyle's 'Schizophrenia: A Scientific Delusion'. Present members of the group continue to work across academic, clinical practice and policy to influence understandings of mental distress.
Professor David Harper and Professor John Read, for example, were co-authors of the 'Power Threat Meaning Framework', an alternative to diagnosis published by the British Psychological Society in 2018. This work drew on their extensive work on trauma, paranoia and mental health, and also cited Professor Nimisha Patel's work in the evidence base. This framework has attracted international interest as providing a psychosocial alternative model to a medical and diagnostic approach. This built on Harper's authorship of the psychosocial textbook: 'The Psychology of Mental Health and Distress', which won the BPS book award and has been widely adopted as a textbook.
