My career has always been that of a clinician-researcher, combining clinical psychology practice with research into cognitive and emotional processes in psychosis, ultimately directed towards the goal of improving psychological treatments.
I studied philosophy and psychology at Cambridge University, before qualifying, in 1981, in clinical psychology at the Institute of Psychiatry, where I subsequently also completed my PhD, under the supervision of David Hemsley. My first appointment was as a lecturer in clinical psychology at the Institute of Psychiatry and as a clinical psychologist at the Bethlem Royal and Maudsley hospitals. I developed my clinical skills working in community clinical settings for people with psychosis, and was strongly influenced by the pioneering work of social psychiatrists Douglas Bennett and Jim Birley. I subsequently held appointments in Oxford, as Academic Director of the Oxford regional clinical psychology training course, and, in 1997, was appointed as Professor of Clinical Psychology at the United Medical and Dental School of Guy’s and St Thomas’ Hospitals and Head of Psychology for Lambeth Healthcare NHS Trust. I returned to work in Camberwell in 2001 as Professor of Clinical Psychology at the Institute of Psychiatry, King’s College London, and Trust Head of Psychology at the South London and Maudsley NHS Trust. In 2010 I was appointed as Clinical Director and Joint Leader for the Psychosis Clinical Academic Group, South London and Maudsley NHS Foundation Trust, King’s Health Partners.
I was made a Fellow of the British Psychological Society in 1995 and was given the Shapiro award in 2002 for achieving eminence in clinical psychology, by the Division of Clinical Psychology of the British Psychology Society. I am a UK accredited cognitive and behavioural therapist (BABCP) and a member of the Academy of Cognitive Therapy (US). In 2008 I was selected as a Senior Investigator of the National Institute of Health Research (NIHR).
activities and interests
My research initially focused on reasoning processes in delusions, and, in 1988, I was the first to identify the ’jumping to conclusions’ reasoning bias, since demonstrated to be consistently associated with delusions in psychosis and now considered to be a phenotype of delusion liability. My early work in delusions also characterised them as multi-dimensional phenomena, on a continuum with everyday beliefs, and involving emotional as well as cognitive processes. This re-conceptualisation of delusions gave rise to new research strategies, examining the continuities as well as differences between delusions and other beliefs in reasoning and other cognitive processes, and the development of a number of new theoretically derived measures (e.g. the Peters et al, Delusions Inventory (PDI), the Maudsley Assessment of Delusions (MADs)).
These findings also led on to the development of therapeutic approaches for psychotic symptoms, drawing on and adapting the new cognitive behavioural therapy for anxiety and depression of AT Beck and colleagues. I was one a small number of UK-based clinical researchers in the late 1980s and early 1990s who initiated this approach. Our research group, formed in the early 1990s, with Fowler, Kuipers, Dunn, Bebbington, and later Freeman, published one of the first controlled trials and manuals of Cognitive Behavioural Therapy for Psychosis. We have continued to work together and have conducted a number of influential clinical trials of this CBT approach.
I have long been interested in service development and involved in the implementation of research into practice. As Head of Psychology for the South London and Maudsley NHS Foundation Trust, I have developed and evaluated new services for people with psychosis, particularly early intervention services incorporating CBT. Recently I co-led, with Tom Craig, the first UK RCT which demonstrated clinical and social benefits of a community-based assertive outreach early intervention service. I have served as psychological interventions lead on the Guideline Development Group of the National Institute of Clinical and Health Excellence (NICE) Schizophrenia Guideline (2003) and the Schizophrenia Guideline Update (2009).
Alongside the work of evaluating CBT and implementation of research, our group has continued to develop theory and to conduct theoretically based investigations. We published a highly cited cognitive model of the positive symptoms of psychosis in 2001, which has been the basis for our recent empirical work into cognitive, social and emotional processes in psychosis.
