RT Journal Article T1 A meta-analytical review of gender-based school bullying in Spain A1 Sanmartín Feijóo, Sandra A1 Rodríguez Fernández, Raquel K1 Bullying K1 Gender K1 LGBT-phobia K1 Prevalence K1 Meta-analysis AB School bullying continues to be one of the main challenges for the education community. Current research indicates that Lesbian, Gay, Bisexual, Transgender, Transsexual, and other LGBT+ people suffer the highest rates of bullying, while other studies suggest that this bullying does not occur based on the victim’s actual sexual orientation or gender identity, but because they do not fit into the traditional gender roles. The aim of the present study was to carry out a meta-analytical study on the prevalence of gender-based bullying against LGBT+ schoolchildren and adolescents in Spain. Methods: The review was carried out following the recommendations of the PRISMA group and allowing us to identify a total of 24 studies. All of these studies were published since 2008, and most of them conducted cross-sectional survey-type research. It was also found that the instrument used to assess bullying varied greatly among studies, resulting in an enormous heterogeneity of research on this topic. Different meta-analyses were carried out according to the profile of involvement in bullying: victimisation, perpetration, and observation. In addition, three target populations were detected in the victimisation research: the general population, pre-identified bullying victims reporting the reasons behind the victimisation, and LGBT+ people. Results: The meta-analyses conducted with R have estimated the prevalence of observation of gender-based school bullying in Spain at 77.3%, perpetration at 13.3%, and victimisation at 8.6% among the general population. When the research focuses on previously identified victims, the rate was 3.6%, while if LGBT+ people are approached directly, the percentage increases to 51%. Conclusions: These rates reveal the need to develop specific preventive strategies in schools. Greater awareness of affective-sexual diversity and respect for those who do not conform to traditional gender roles should be promoted.
