This thesis studies the influence of the parental context on bullying within educational settings, taking into account the context of the classroom.
The thesis is structured in three cross-sectional studies, with a main focus on (dysfunctional) parental context and how it influences bullying behaviour inside the classroom in adolescent population. The studies collect empirical evidence about the influence of the parental context and how it relates with bullying and other relevant variables in classroom contexts with different methodological approaches. To understand such influence, an ecological framework (Bronfenbrenner, 1979) is applied to bullying, alongside state of the art research to understand the phenomenon.
Study 1 examines a sample of 2.852 students (46.95% females) with ages between 12 and 17 (M = 13.87, DT = .95) distributed across 25 educational centres in Madrid. The sample is split into two groups those who self-reported physical abuse in the parental context and those who did not. In regards to academic performance, Chi-square analysis were conducted using certain indicators and demonstrated significant differences between those who reported parental maltreatment and those who did not (χ²=13.07) showing low effect sizes (V Cramer=.06). Besides, t-test comparisons were conducted of student’s sociometric data with results indicating significant differences in rejection, lack of acceptance from their peers and number bullying and victimization episodes within classrooms to those students who suffered parental maltreatment. Finally, differences in behavioural traits related with bullying roles showing a tendency to withdrawal and aggression characterised by victim and bully roles respectively to those who report parental maltreatment. On the other hand, the prosocial role favoured to those who did not report parental maltreatment, the effect size for all these differences were small too (d Cohen=-.34 - .38). Results highlight the risk that students who suffer parental maltreatment have in relationship to bullying dynamics, they have higher probabilities to be involved in bullying events, dysfunctional socialisation processes and tendencies to acquire behavioural traits as bully or victim roles inside the classroom.
Study 2 uses the same sample of adolescent students distributed across secondary education courses. It applies multi-level regression models, which allows grouping classrooms for each centre (n=133), hence accounts for the group influence of bullying and interactions that take place between the individual level and classroom levels. Correlation analyses were conducted for all study variables, showing a significant association between behavioural problems and those who were involved in bullying as perpetrators, and also a significant relationship between parental maltreatment, victimization and externalizing behavioural variables in the study, showing small correlations (r < .20). In the multi-level model, bullying and victimization were identified as outcome variables whereas behavioural problems alongside sex and parental maltreatment as predictors at the individual level. In the group level, the average of classroom bullying and the average of classroom victimization were selected as predictors representing classroom climate. The results from the multi-level models showed how sex and parental maltreatment are significant predictors of victimization, while behavioural problems and sex were bullying predictors at the individual level. In reference to the cross-level interactions a moderation effect was found between parental maltreatment and the average classroom bullying when predicting victimization (b = .069, t = 4.44, p < .001). These results indicate that parental maltreatment suffered by the adolescent is related to the acquisition of victim traits in the classroom, this tendency is aggravated when we find high normative levels of bullying within that classroom. In conclusion, as the ecological-transactional model postulates, the vulnerability acquired by adolescents through parental maltreatment transfers to the school context, this demonstrates the influence of the environment in the risk and protective mechanisms that take place in between contexts of the adolescent’s ecology.
Study 3 investigates the influence of the parental context from a more exogenous perspective. It aims to explore the influence of family climate through the adolescent self-report of parental rejection, bullying and victimization, while accounting for normative levels of bullying in the classroom and depression as shared risk factor for bullies and victims. A sample of 1.208 (47.8% females) with ages ranging between 11-18 years (M=13.65, DT=1.295) was collected across 27 public educational centres in Mexico distributed in 45 classrooms. Two 1-1-1 multi-level mediation analysis were conducted to explore the influence of parental rejection as a mediator variable between the relationship amongst bullying and victimization as predictors and depression as an outcome. Multi-level mediation analysis allows us to observe mechanisms in the relationships between dependent and independent variables on two hierarchical levels, the individual level inside of the classroom and the influence of the classroom context when comparing the between classroom level on the analysis. The results show a partial mediation of parental maltreatment in the relationship mechanism between victimization, bullying and depression at the intra-class level, demonstrating a significant indirect effect. At the between-classrooms level, only a significant effect and direct association was found between parental rejection and depression. Results suggest that there are important links between depression and perceived parental support by adolescents. The implications of these findings advocate for the inclusion of the parental context in programs aimed to improve well-being and bullying reduction within schools.
This thesis concludes the appropriateness of ecological frameworks to study the bullying phenomena and its contextual influences. Dysfunctional parental context variables are risk factors associated with bullying dynamics in the classroom. Finally, contextual influences are crucial to understand the phenomenon in complex educational environments in order to evaluate, improve and design anti-bullying programs where parental, school and individual interventions should be integrated.
