2021/01: Impact of bullying on academic performance. A case study for the Community of Madrid
Bullying is a problem that affects children and teenagers around the world and its repercussions can endure throughout adult life. Its prevalence is, in part, a product of the lack of information and the paucity of studies which analyse the wide-ranging consequences for the individuals involved. The main objective of this research is to study the incidence of bullying on the academic performance of students in education centres in the Madrid Region. The databases used are those of Competency Tests carried out on all 10th grade students in Madrid during the year 2017. These external assessment tests evaluate Spanish language, English language, Mathematics, and Geography and History. Along with these tests, the students, their families, their teachers and head teachers complete comprehensive questionnaires. To analyse all these data, we carry out a multilevel methodological approach to identify the quantitative association of bullying with academic performance and to estimate the probability that performance is affected by the level of bullying that exists in the education centres. The results indicate that bullying has a negative impact on all the competencies evaluated, that the probability of a lower academic performance increases in environments where there is bullying and that bullying can affect students with low or high academic achievement in different ways, depending on what competency is evaluated.
