With the development of advanced media technologies, cyberspace is gradually transforming from temporal immersion into a state of new normal. An increasing proportion of our daily lives has become a mix of physical and virtual worlds. As a complex social psychological phenomenon, online social identity has attracted widespread attention from academia to industry. Identity-related issues have been noted as an important subject of Internet interdisciplinary research, including social psychology, sociology, personality psychology, and health psychology. Communication in cyberspace always carries some degrees of anonymity, for users present virtual identities constructed by themselves in cyberspace, hiding their real identities and constructing their online identities as a form of social identity enactment. On the other hand, online media provides tools and environments for virtual identity building. Although the anonymity of the internet facilitates the subjects' construction of their virtual identity, their online virtual identity is not completely anonymous and can be identified and authenticated online, thereby meaning we can research how online identity relates to real world identity. Identification is a social process that matches internal self-identity with external identity types, and it is also a process and a reflection of internal perceptions, and mere identification with a group has been shown to dramatically affect behavior (as per social identity theory).

Changing health-related behavior is for many people a lonely and isolating experience. Individual willpower is often not enough, particularly in addressing addictive behavior, but research increasingly points to the potential of group identity to shape behavior change and support recovery. This important collection explores the social and cognitive processes that enable people who join recovery groups to address their addictive issues. In an era of increasing concern at the long-term costs of chronic ill-health, the potential to leverage group identity to inspire resilience and recovery offers a timely and practical response. The book examines the theoretical foundations to a social identity approach in addressing behavior change across a range of contexts, including alcohol addiction, obesity and crime, while also examining topics such as the use of online forums to foster recovery. It will be essential reading for students, researchers and policy makers across health psychology and social care, as well as anyone interested in behavioral change and addiction recovery.

Social problems in many domains, including health, education, social relationships, and the workplace, have their origins in human behavior. The documented links between behavior and social problems have compelled governments and organizations to prioritize and mobilize efforts to develop effective, evidence-based means to promote adaptive behavior change. In recognition of this impetus, The Handbook of Behavior Change provides comprehensive coverage of contemporary theory, research, and practice on behavior change. It summarizes current evidence-based approaches to behavior change in chapters authored by leading theorists, researchers, and practitioners from multiple disciplines, including psychology, sociology, behavioral science, economics, philosophy, and implementation science. It is the go-to resource for researchers, students, practitioners, and policy makers looking for current knowledge on behavior change and guidance on how to develop effective interventions to change behavior.

We live in an ever-changing social world, which constantly demands adjustment to our identities and actions. Advances in science, technology and medicine, political upheaval, and economic development are just some examples of social change that can impact upon how we live our lives, how we view ourselves and each other, and how we communicate. Three decades after its first appearance, identity process theory remains a vibrant and useful integrative framework in which identity, social action and social change can be collectively examined. This book presents some of the key developments in this area. In eighteen chapters by world-renowned social psychologists, the reader is introduced to the major social psychological debates about the construction and protection of identity in face of social change. Contributors address a wide range of contemporary topics - national identity, risk, prejudice, intractable conflict and ageing - which are examined from the perspective of identity process theory.
