The Prevalence and Correlates of Sibling Bullying Victimisation: A Socio-Ecological Investigation of over 40,000 children in 20 countries

Research output: Working paperPreprint


Objective. The goal of the current study was to determine the prevalence and correlates of sibling bullying victimisation in 20 countries across the world. Method. Existing data from an international study of over 40,000 children, the Children's World Survey, was analysed. Children aged 10- and 12- years old reported on physical and verbal bullying by siblings and on various other aspects of their lives. Regression models were fitted to investigate individual- (e.g., sex), family- (e.g., resources, functioning etc.), peer- (e.g., friendships), neighbourhood- (e.g., feeling safe, belonging etc.), and school-level (e.g., bullying, positive school environments etc.) correlates of sibling bullying victimisation. Results. On the whole, the prevalence of sibling bullying victimisation was 25%. That is, 1 in 4 children were physically hurt or called unkind names more than three times in the last month by a sibling (excluding fighting or play fighting). The prevalence of sibling bullying victimisation varied by country; ranging from 8%-56%. Whilst individual- and family-level factors were strongly associated with sibling bullying victimisation, peer-, neighbourhood-, and school-level factors were also important. Conclusion. These findings demonstrate that, if causality can be established, sibling bullying victimisation is influenced by a complex system of factors within and outside the home. Importantly, they demonstrate that what happens in neighbourhoods and schools is important for bullying within the home, providing novel targets for intervention.
