RT Article T1 Measuring the Extent and Nature of Adverse Childhood Experiences (ACE) among Former White Supremacists JF Terrorism and political violence VO 34 IS 6 SP 1207 OP 1228 A1 Windisch, Steven A2 Simi, Pete A2 Blee, Kathleen M. 1953- A2 DeMichele, Matthew LA English YR 2022 UL https://krimdok.uni-tuebingen.de/Record/1814881042 AB While progress has been made to understand mid-life correlates associated with extremist participation, much less research focuses on adolescent risk factors. The purpose of the current study is to expand upon the focus on individual-level correlates by assessing the extent and nature of childhood adversity among a sample of former white supremacists. The current study relies on in-depth life-history interviews with ninety-one North America-based former white supremacists and the Adverse Childhood Experiences questionnaire. Overall, the current sample contained elevated rates of childhood risk factors with 63 percent of participants having experienced four or more adverse experiences during the first eighteen years of their lives (as compared to 55 percent of a comparison “high risk” sample and 16 percent of the U.S. general population sample). Furthermore, participants discussed a variety of maladaptive coping strategies associated with adversity that generated vulnerabilities to adolescent misconduct and extremism early in the life-course. Our findings indicate that extremist onset does not begin with a single life event but rather is generated, and further exacerbated by the cumulative impact of multiple adverse experiences during childhood.
