A landmark volume in the scientific study of identity formation and youth development, this fully revised second edition synthesizes sociological and psychological approaches to the study of identity. It illuminates the challenges and opportunities that contemporary young people face as they attempt to form identities in societies undergoing transition. The book introduces simplified identity formation theory, which helps newcomers connect the dots across a broad and promising area of study. Part I places the “identity question” in historical and cultural context, providing a multidimensional framework for studying the developmental dynamics of identity formation. Part II examines the development of perspective taking and moral reasoning, exploring their relationship to ethics and agency in identity formation. Part III investigates scientific evidence concerning identity formation in various societal contexts, implications for understanding youth mental health problems, and the most promising treatments, programs, and practices for addressing the identity issues young people face today. This book is an essential text for advanced undergraduate and graduate students studying self and identity development within developmental psychology, social psychology, clinical psychology, and sociology. Educators and practitioners in child welfare, mental health services, social work, youth and community work, and counseling will also benefit from its introductory and jargon-free nature. For the new edition: “This book’s spirit is open, curious, and practical. What is the self? How are the self and identity different from each other? How can one achieve a purpose driven and ethical life? Why does living in a late modern society make a serious tussle with one’s identity commonplace? By thoughtfully answering these kinds of historically nagging and/or nuanced questions about the self and identity, the authors in the process, leave traditional boundaries, arguments, and dichotomous thinking far behind and encourage the reader to do the same. The authors offer an original vision of what identity can be and how it can be supported. And, by sharing what is known about a diverse range of science-based, actionable solutions to the problems of identity development, this book is a vital resource for caring adults who support this and future generations. This book delivers―in its ideas and in practice. In this book, the authors challenge us to work towards an inclusive vision and authentic inter-generational concern for the development and welfare of humanity as the only ‘in-group’ of any real importance, which is a sorely needed message that we should take to heart and be inspired by.” Laura Ferrer-Wreder, PhD, Professor of Psychology, Stockholm University, Sweden “Identity Formation, Youth, and Development: A Simplified Approach provides a clear and thoughtful look at how identity develops, blending research, theory, and practical applications in a way that is both engaging and accessible. This updated edition does an excellent job of connecting identity formation to real-world challenges, particularly the growing mental health struggles faced by today’s youth. The authors skillfully integrate insights from psychology, sociology, and developmental science, offering a well-rounded perspective that makes this book useful for researchers, educators, and practitioners alike. Its emphasis on identity-based interventions and their practical applications makes it a timely and valuable resource for anyone interested in understanding and supporting youth development.” Mojtaba Habibi Asgarabad, PhD, Researcher in Psychology, Norwegian University of Science and Technology, Norway “This book serves a strong new edition to the identity literature, providing a comprehensive review of identity across various traditions and contextualized particularly within the Western cultural context. In addition, the authors provide compelling arguments for the need to focus on identity-related problems as particular manifestations of recent socio-cultural changes and, most critically as part of this new edition, provides a framework for integrating models of identity into intervention and prevention efforts. In turn, Identity Formation, Youth, and Development is a fundamental textbook for any researcher conducting work on identity development and any instructor seeking to provide an in-depth course on the subject.” Alan Meca, PhD, Associate Professor of Psychology, University of Texas at San Antonio “This book represents a significant contribution to the identity development research literature, situating identity formation within the broader context of applied developmental science. For educators and practitioners working directly with youth, this book serves as an indispensable guide, providing evidence-based strategies and insights into how identity formation can be fostered in educational and therapeutic settings. Clinicians will find the book inval
