This thesis examines the influence of environmental factors on children’s risk of becoming involved in bullying, and in promoting resilience to bullying victimization. By integrating longitudinal, multivariate and genetically sensitive designs, this research helps to strengthen understanding of the causal role of different risk and protective factors for childhood bullying involvement. The three main aims of this thesis are to: 1) identify early socio-environmental risk factors for bullying involvement 2) investigate the aetiology and outcomes of chronic bullying victimization, and 3) identify factors within the home environment that help protect bullied children from adverse outcomes. Research was conducted using data from the prospective Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative sample of 1,116 twin pairs and their families. Reports on bullying involvement, children’s mental health and family characteristics have been collected from multiple informants when the children were aged 5,7,10 and 12 years. School, neighbourhood and family factors were found to be independently associated with early bullying involvement, even after controlling for the effects of children’s individual characteristics. Behavioural genetic analyses revealed that both environmental and genetic factors influence the persistence of bullying victimization across the transition from primary school to secondary school. A genetically sensitive twin differences design showed that families exert an environmental effect on children’s vulnerability and resilience to bullying victimization. The results of this thesis indicate that children’s individual characteristics including their genes influence their risk for bullying involvement and their likelihood of becoming chronically victimized across different school settings.
We have developed the following database of research theses on bullying from all academic institutions in the UK and Ireland. The aim of this database is to assist those who are interested in the field of bullying and want to see what research has already been done. We have attempted to ensure that we have included all relevant theses here; but if there is an omission please let us know by emailing geraldine.kiernan@dcu.ie.
The database is here for information purposes. Those who want access to the texts of the theses need to contact the author, the relevant institution, or both.
