Adverse Childhood Experiences and Trajectories of Firearm Exposure in Childhood.

OBJECTIVE: To examine the longitudinal relationship between exposure to adverse childhood experiences (ACEs) in early life and trajectories of firearm exposure from early to middle childhood (ages 5-9 years old). STUDY DESIGN: Data from the Longitudinal Studies of Child Abuse and Neglect (LOGSCAN) study were used. The LONGSCAN study was a prospective study in the United States and contained data from 1354 children from age 4 to age 18 years old. Exposure to ACEs was measured through the wave 1 interview (age 5 years old) and trajectories of firearm exposure were created using data from waves 1 (age 5 years old) and two (age 9 years old). RESULTS: Two trajectories of firearm exposure in childhood were identified: a low exposure group and a group with persistently-high firearm exposure from ages 5 to 9 years old. ACEs were associated with membership in the high exposure group and children with four or more ACEs had over twice the odds of membership in the high exposure group compared with children with zero ACEs. CONCLUSION: ACEs exposure in early childhood is associated with persistently-high exposure to firearms from early to middle childhood. This finding highlights the need for pediatricians to consider screening for both ACEs and firearm exposure in routine examinations, as well as the need for future research to identify and evaluate interventions intended to address exposure to adversity and firearms.

Taking the problem of colliders seriously in the study of crime: A research note.

Objectives: We provide a brief overview of collider bias and its implications for criminological research. Methods: Owing to the nature of the topics studied, as well as the common data sources used to carry out much of this research, work in the field may often become vulnerable to a specific methodological problem known as collider bias. Collider bias occurs when exposure variables and outcomes independently cause a third variable, and this variable is included in statistical models. Colliders represent somewhat of a paradox in that there is scholarship discussing the issue, yet it has managed to remain a relatively cryptic threat compared to other sources of bias. Results: We argue that, far from being an obscure concern, colliders almost certainly have pervasive impact in criminal justice and criminology. Conclusion: We close by offering a general set of strategies for addressing the challenges posed by collider bias. While there is no panacea, there are better practices, many of which are underutilized in the disciplines that study crime and its attendant topics.

The conditioning effects of positive experiences on the ACEs-offending relationship in adolescence.

BACKGROUND: Research shows that adverse childhood experiences (ACEs) are problematic and may impact delinquency and arrest in adolescence. However, resiliency theories suggest the association between ACEs and delinquency/arrest may be mitigated by positive childhood experiences (PCEs). OBJECTIVE: This study tests the hypothesis that an accumulation of PCEs ameliorates the relationship between ACEs and delinquency and arrest during adolescence. PARTICIPANTS AND SETTING: Prospective data were collected from approximately 800 participants in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). METHODS: Self-report data from 16-year-old participants were used to measure the two dependent variables: the number of delinquent acts committed and having at least one arrest in the past year. Count measures reflected the number of ACEs and PCEs, with the former based on reports from child protective services, caregivers, and youth collected from ages 4-12, and the latter based on self-reports at age 12. Negative binomial models analyzed delinquency outcomes, logistic regression models examined arrest, and interaction terms assessed moderating effects. RESULTS: ACEs were associated with significantly more delinquent acts but not arrest, and PCEs were associated with significantly fewer delinquent acts but not arrest. PCEs significantly reduced the relationship between ACEs and delinquency but only for youth with moderate levels of ACEs. CONCLUSIONS: Findings indicate a need for additional research measuring the moderating effects of a variety of PCEs and to the need to enhance positive experiences for youth to prevent delinquency.
