Adverse Childhood Experiences and Bullying: Findings from the Growing Up in Scotland Cohort.

Adverse childhood experiences (ACEs) are defined as stressful or traumatic events occurring within a child's family environment during their first 18 years of life. Research examining the associations between exposure to ACEs in childhood and bullying experiences in adolescence is sparse. To address this gap, data from the first 10 sweeps of the Growing Up in Scotland prospective cohort study was used to evaluate the relationship between 6 different ACEs and the risk of being bullied or engaging in bullying others at age 14 among a sample of 2,669 adolescents. Multiple univariable logistic regression models were fitted to explore independent associations between each of the six ACEs measured, 1+ ACE and 3+ ACEs and bullying perpetration and victimization, respectively. Results showed that a high proportion of young people in Scotland experience bullying victimization (31%) and a very high percentage reported exposure to at least one type of adversity (73.6%). Young people whose parents reported drug or alcohol misuse and females whose parents had divorced or separated had higher odds of engaging in bullying others. Having a parent who had mental health problems was the only ACE that predicted higher odds of experiencing bullying. Substance misuse in the family predicted a higher risk of bullying victimization for females. Logistic regression analyses further showed that females with greater exposure to ACEs were more likely to engage in bullying in mid-adolescence. Our findings underscore the importance of understanding bullying perpetration as a maladaptive way to manage life stressors.
