Patterns of Partner and Nonpartner Violence Among High-Risk Youth

Purpose: Perpetration of violent behavior begins to increase in adolescence and peaks in young adulthood (e.g., age 18–29) before decreasing by the early 30s. Considerable variability in reported perpetration, targets, and severity of violence suggests youth may change their violent behavior patterns over time. Methods: We use latent transition analysis to describe profiles of violent behavior against partners and nonpartners in an at-risk sample of young adults (N = 599; 59% male; 61% African-American) over a period of 2 years. Results: A four-class solution provided the best fit to the data, with classes corresponding to (1) nonviolent behavior (48.3% of the sample); (2) violent only toward nonpartners (22.3%); (3) violent only toward partners (16.0%); and (4) violent toward nonpartners and partners (13.4%). Participants' sex, race, age, previous violent injury, antisocial behavior, alcohol dependence, and possession of firearms were associated with baseline class membership. Conclusions: Implications for prevention are discussed.
