Graham Davey is Emeritus Professor of Psychology at the University of Sussex. His research interests extend across mental health problems generally, and anxiety and worry specifically.

He is a former president of the British Psychological Society and is currently editor-in-chief of the Journal of Experimental Psychopathology which publishes cutting-edge research on anxiety and anxiety-related problems.

Andy Field is Professor of Child Psychopathology at the University of Sussex. He has published over 70 research papers, 27 book chapters, and 17 books mostly on child emotional development and statistics. He is the founding editor of the Journal of Experimental Psychopathology and has been an associate editor and editorial board member for the British Journal of Mathematical and Statistical Psychology, Cognition and Emotion, Clinical Child and Family Psychology Review and Research Synthesis Methods.

His ability to make statistics accessible and fun has been recognized with local and national teaching awards (University of Sussex, 2001; the British Psychological Society, 2007), a prestigious UK National Teaching Fellowship (2010), and the British Psychological Society book award (2006).

Andy has been publishing with SAGE for 13 years, and we are incredibly proud to have worked with him on the development of what has become a world-wide phenomenon for teaching statistics across the social and behavioural sciences,” said Ziyad Marar, Global Publishing Director, SAGE. “Increasingly now, the higher education market is demanding interactive material that engages the student and supports their learning within a digital environment.

The work we have done on the new edition meets this need in an innovative and highly effective way, but at its heart this book will always be the unique expression of an extraordinarily gifted author with a passion for teaching. SAGE was founded on the belief that a true education creates healthy minds and healthy cultures, and Andy Field's 4th edition is an iconic example of that mission.”
