Purpose
To understand the etiology of violence among ethnically-diverse men using a nationally representative and longitudinal sample of youth.
Methods
Participants included 4,322 adolescent men followed from ages 13 to 32 from the National Longitudinal Study of Adolescent Health (Add Health). Trajectories of violence were estimated, and multinomial regression procedures were used to evaluate multiple domains of risk and protective factors for violence.
Results
Three profiles of violence (non-violent, desistors, and escalators) were identified. There were no substantial differences in the patterns of violent behavior across race/ethnicity; however, the prevalence of violence differed by racial/ethnic group. After accounting for violent behavior at Wave I, peer marijuana use (OR = 1.20), alcohol use (OR = 1.50), group fighting (OR = 2.23), and Wave I violence (OR = 4.34) were identified as risk factors for desistance, while only Wave I violence predicted escalation (OR = 2.27).
Conclusions
Three trajectories of serious violence, including a late-onset group, were identified; however, few risk and protective factors were associated with membership in this group. Risk and protective factors for violence prior to age 13 should be targeted for prevention.
