Bullying, by its nature and consequences, has become a central concern in schools, which have developed different ways of facing it. The main objective of this paper is to assess the effectiveness of a prevention and intervention program of bullying and cyberbullying in a sample of 320 students in a school for girls in Santiago de Chile, through a pre-post design. The program used preventive and comprehensive strategies aimed to perform interventions at the different levels in the school system: school, classroom, individual and family. Results showed that the program is effective in diminishing the report of witnessing bullying and victimization from bullying via Internet. The effectiveness of the program could be due to the multi-level targets of the program that taps different aspects, actors and domain of this pervasive problem.
