This study focuses on the issue of school bullying and explores the potential of video games as a tool to prevent and address this problem. To accomplish this, the video game Monité, specifically designed for the prevention of school bullying, was utilized, using the paradigm of digital game-based learning as an intervention methodology that emphasizes its educational and recreational potential. This study was conducted using a quasi-experimental approach, employing a pre-test and post-test design with a non-equivalent control group. The sample consisted of 92 boys and girls from fifth and sixth grade in primary education in the province of Cáceres, Spain. Data were collected through questionnaires from the System for the Evaluation of Children and Adolescents (SENA), which allowed for the gathering of information on peer problems, school problems and family issues. The results show that there are significant differences between the intervention group and the control group regarding problems external to individuals. In conclusion, this study investigates the use of the video game Monité as a tool to prevent school bullying and analyzes its impact on students’ perception of external agents such as family, peer group, and school. Our findings support its implementation in educational environments as an effective strategy.
