Abstract
School is the main scenario of social actions where the foundations of interpersonal relations other than those of the family are laid down; it has therefore become one of the main settings for psychoeducational research. In recent years, the phenomena of poor interpersonal relations, gratuitous and cruel aggression, the resulting victimization, and the construction of a psychopathic and inmoral personality have been the object of intense research. The monographic section presented herein aims to provide the readers of Psicothema with a series of investigations that trace the most important research lines developed in the international community on bullying and cyberbullying.
