Over the past decade, Professor Norton’s research has been focused on developing and evaluating transdiagnostic and diagnosis-specific factors across anxiety and other emotional disorders, and translating these factors into efficacious and efficient interventions. This work involves a combination of basic and experimental research to better understand common and unique aspects of affective psychopathology, and clinical outcomes research to develop and evaluate new or modified interventions to target these core features. As a result, Norton’s research and treatment are at the forefront of an international movement toward transdiagnostic models of psychopathology.
His work is wide-ranging and highly cited, and includes cross-sectional, longitudinal, and clinical trial methodologies investigating the impact of anxiety disorders, assessment and diagnosis, comorbidity, and treatment outcomes. Many of his papers on transdiagnostic CBT appear on the “most cited papers” listings of top journals in clinical psychology and psychiatry.
His intervention work has focused on adults with anxiety disorders, and includes psychological clinical trials. His work investigating the impact of transdiagnostic CBT has been of major interest among academic and applied circles, and the treatment protocols derived from this work have been adopted in many private clinics and hospitals.
He has nearly 180 journal articles and chapters, and 4 published books (one of which has been translated to 5 different languages). He serves on the Editorial Board of Cognitive Therapy and Research and Journal of Anxiety Disorders, and has secured over $2,000,000 in funding since 2015.
Peter’s outstanding contributions to psychology have led to his election to Fellow Status in the Society of Clinical Psychology (APA) in 2018, receiving the Australian Psychological Society (APS) Outstanding Academic Mentor Award in 2019, and receiving the Distinguished Career Award by the Australian Association for Cognitive and Behaviour Therapies (AACBT) in 2020. He is a PsyBA registered Clinical Psychologist.
