Dr. Flett is also internationally recognized for his seminal contributions to research and theory on the role of perfectionism in pathology. He is the author, with Paul L.

His work on mattering has been featured in the New York Times and has been the topic of interviews in Scientific American and the Wall Street Journal.

"This is such a fascinating book with a powerful message: All young people need to feel that they matter. A must-read for anyone interested in the mental health and well-being of children and adolescents." - Rory O'Connor, PhD, Professor of Health Psychology, University of Glasgow, Glasgow, Scotland, UK, and author of When It Is Darkest: Why People Die by Suicide and What We Can Do to Prevent It "From the first page, Dr. Flett draws readers into a fundamental understanding of the need for children and adolescents to feel that they matter. He explores what mattering is, why it is important, and the potential consequences to youth from feeling that they don’t matter, including addiction, aggression, depression, and suicide. A leader in the field of mattering research, Dr. Flett works to ensure that people of all ages feel that they are important to and valued by others." - Robin Kowalski, PhD, Professor of Psychology, Clemson University, Clemson, SC, United States "In an engaging style, Dr. Flett makes a clear case for why “mattering matters” to the healthy development of children and adolescents. This groundbreaking resource provides a comprehensive summary of the theory and research on mattering, and is a must-read for clinicians, researchers, educators, and trainees who are interested in supporting resilience and flourishing among our next generation." - Randi E. McCabe, PhD, Professor, Department of Psychiatry and Behavioural Neurosciences, McMaster University, Hamilton, ON, Canada; Fellow of the Canadian Psychological Association; and coauthor of Cognitive-Behavioral Therapy in Groups "If you’ve ever wondered what truly makes children and adolescents feel seen, valued, and connected, this book is for you. It introduces the powerful idea of “mattering”— a concept that many don’t realize is central to everything from mental health to motivation and social development. With clear insights and real-world examples, the book helps parents, educators, and anyone who cares about young people understand how deeply mattering impacts their lives and well-being." - Virgil Zeigler-Hill, PhD, Distinguished Professor of Psychology, Oakland University, Oakland, MI, United States "Gordon Flett’s work offers a comprehensive assessment of early life experiences of mattering to others. This book will benefit clinicians, academic researchers, and parents. I highly recommend it." - John Taylor, PhD, Professor and Director of the Center for Demography and Population Health, Florida State University, Tallahassee, FL, United States "Dr. Gord Flett has taken up the scholarship of mattering, and its implications for children and youth, in an energetic and compelling manner. Mattering as a Core Need in Children and Adolescents: Theoretical, Clinical, and Research Perspectives is a critical addition to the necessary discussion of how to prevent maltreatment, emotional abuse, and neglect, as well as violence to self and others. This book should be required reading for public health officials who seek to build multisystemic resilience, promote mental health, and reward good citizenry. In short, this evidence-based presentation attests to the finding that people who feel they matter, do things that matter. Now, more than ever, we need this book to guide us towards a reinvigoration of positive relationality." - Christine Wekerle, PhD, Associate Professor, Pediatrics and Psychiatry & Behavioural Neurosciences, McMaster University, Hamilton, ON, Canada
