Check out this new article by Zoe Marchment, Caitlin Clemmow and Paul Gill exploring how adverse childhood experiences (ACEs) might shape a person’s susceptibility to violent extremism. The study looks beyond simple counts of childhood trauma to understand whether different patterns of adversity relate differently to extremist tendencies, and whether those relationships vary by gender.
Using a nationally representative sample of 1,500 adults in the United Kingdom, recruited through the online panel Prolific, the researchers collected data on ten types of adverse childhood experiences such as physical, emotional and sexual abuse, neglect, and household problems like mental illness, substance use or imprisonment of a caregiver. They also measured susceptibility to violent extremism through four items from the Radicalism Intention Scale, which captures willingness to support or engage in violence for a cause. To move beyond individual scores, they applied latent class analysis, a statistical technique that identifies clusters of people who share similar ACE profiles.
Four clusters emerged. The first, “Child Abuse Victimisation”, included those with high probabilities of having experienced physical and psychological abuse from caregivers. The second, “High ACEs”, captured those with high probabilities across all ten forms of adversity. The third, “Unstable Home”, reflected chaotic family environments with drug use or mental illness but low direct abuse. The final group, “Low ACEs”, included those reporting little or no adversity. The researchers then tested whether people in these different groups scored differently on the measure of susceptibility to violent extremism.
Among men, those in the “Child Abuse Victimisation” and “Unstable Home” groups were significantly more susceptible to violent extremism than those who had experienced few or no ACEs. Among women, higher susceptibility was found only for those in the “High ACEs” group, suggesting a higher threshold of trauma exposure may be needed for women to show a similar risk pattern.
These findings indicate that specific patterns of childhood adversity, rather than the total number of events, may be more informative for understanding who is vulnerable to extremist thinking. The study supports a trauma-informed approach to prevention and intervention. Addressing the long-term psychological and emotional effects of childhood abuse and instability through early mental health support, cognitive behavioural therapy or mindfulness programs could help reduce vulnerability not only to extremism but to a wide range of harmful outcomes.
