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.

“After decades of research on dysfunctional eating and lack of physical activity, research attention has finally turned to the role of digital technology in eating behaviors and eating disorders. This timely volume offers a thoughtful and wide collection of chapters discussing the possible effects of digital technologies, from those enhancing healthy eating behaviors to those that encourage disordered eating. Highly recommended for both professionals and scholars.” Prof. Giuseppe Riva, Università Cattolica del Sacro Cuore, Milan, Italy. This book examines in depth the multifaceted roles of digital technologies in the eating behaviors and eating disorders. Coverage reflects a broad theoretical and empirical knowledge of current trends in digital technology use in health behaviors, and their risks and benefits affecting wellbeing, with focus on eating behaviors and eating disorders. The authors use both qualitative and quantitative data to focus on the digital lived experiences of people and their eating related behaviors. Among the topics covered: The quality of eating-oriented information online Technology, body image, and disordered eating Eating-oriented online groups Using mobile technology in eating behaviors Usage of digital technology among people with eating disorders What healthcare professionals should know about digital technologies and eating disorders Technology-based prevention and treatment programs for eating disorders A potential source of discussion and debate in various fields across the social sciences, the health sciences, and psychology, Digital Technology, Eating Behaviors, and Eating Disorders will be especially useful to students, academics, researchers, and professionals working in the fields of eating behaviors and eating disorders.

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.
