This volume brings together research on cyberbullying across contexts, age groups, and cultures to gain a fuller perspective of the prevalence and impact of electronic mistreatment on individual, group, and organizational outcomes. This is the first book to integrate research on cyberbullying across three contexts: schools, workplaces, and romantic relationships, providing a unique synthesis of lifespan contexts.For each context, the expert chapter authors bring together three different ‘lenses’: existing research on the predictors and outcomes of cyberbullying within that context; a cross-cultural review across national borders and cultural boundaries; and a developmental perspective that examines age-related differences in cyberbullying within that context. The book closes by drawing commonalities across these different contexts leading to a richer understanding of cyberbullying as a whole and some possible avenues for future research and practice.This is fascinating reading for researchers and upper-level students in social psychology, counseling, school psychology, industrial-organizational psychology, and developmental psychology, as well as educators and administrators.
