- Incarceration is a disruptive event that is experienced by a considerable proportion of the United States population. Research has identified social factors that predict incarceration risk, but scholars have called for a focus on the ways that individual differences combine with social factors to affect incarceration risk. Our study is an initial attempt to heed this call using whole-genome data. We use data from the Health and Retirement Study (HRS) (N = 6716) to construct a genome-wide measure of genetic propensity for aggressive behavior and use it to predict lifetime incarceration risk. We find that participants with a higher genetic propensity for aggression are more likely to experience incarceration, but the effect is stronger for males than females. Importantly, we identify a gene-environment interaction (G x E)-genetic propensity is reduced, substantively and statistically, to a non-significant predictor for males raised in homes where at least one parent graduated high school. We close by placing these findings in the broader context of concerns that have been raised about genetics research in criminology.

Childhood risk factors for adolescent victimization : A discordant twin design
- 2016
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- In this study we considered the effect of childhood risk factors on adolescent victimization, measured at 18 years of age. We analyzed 1000 twipairs born 1994–1996 who were members of the Environmental Risk (E-Risk) Longitudinal Study, a prospective cohort study from the United Kingdom. We considered risk factors from two developmental periods (early childhood and early adolescence) and across multiple domains (individual, family, neighborhood): IQ, under controlled temperament, parent antisocial behavior, severe childhood victimization from ages 5 to 12, neighborhood socioeconomic, and neighborhood social cohesion. These childhood and early adolescence risk factors were tied to adolescent victimization. Many of these risk factors, however, are known risk factors for criminal behavior. Additionally, criminal behavior and victimization have been shown to be correlated in past research and were correlated the present sample of 18 year-olds (r = .40). We thus reanalyzed the relationship between the risk factors and victimization while controlling for adolescent offending. We found that the effect size for many of the childhood risk factors for victimization decreased and some became non-significant, suggesting that the risk factors described adolescents who were both victims and perpetrators. However, we found that one of the most robust predictors of adolescent victimization was childhood victimization, implying a continuity in victimization risk over the life-course. This presentation will include a comparison for twins discordant for severe childhood victimization.

- Purpose It is well-established that victims and offenders are often the same people, a phenomenon known as the victim-offender overlap, but the developmental nature of this overlap remains uncertain. In this study, we drew from a developmental theoretical framework to test effects of genetics, individual characteristics, and routine-activity-based risks. Drawing from developmental literature, we additionally tested the effect of an accumulation of adverse childhood experiences (ACEs). Methods Data came from the Environmental Risk (E-Risk) Study, a representative UK birth cohort of 2232 twins born in 1994-1995 and followed to age 18 (with 93% retention). Crime victimization and offending were assessed through self-reports at age 18 (but findings replicated using crime records). We used the classical twin study method to decompose variance in the victim-offender overlap into genetic and environmental components. We used logistic regression to test the effects of childhood risk factors. Results In contrast to past twin studies, we found that environment (as well as genes) contributed to the victim-offender overlap. Our logistic regression results showed that childhood low self-control and childhood antisocial behavior nearly doubled the odds of becoming a victim-offender, compared to a victim-only or an offender-only. Each additional ACE increased the odds of becoming a victim-offender, compared to a victim-only or an offender-only, by approximately 12%, pointing to the importance of cumulative childhood adversity. Conclusions This study showed that the victim-offender overlap is, at least partially, developmental in nature and predictable from personal childhood characteristics and an accumulation of many adverse childhood experiences.
