Results indicated that both chronic and late-increaser patterns of youth violence development increased the likelihood of later IPV perpetration. Factors that partially mediated the relationship between youth violence and IPV were identified and were related to one’s partner (prior and current antisocial behavior) and to the surrounding community (availability of support systems). Perpetrator individual characteristics were not significantly related to later use of IPV. The findings suggest that the risk of IPV could be reduced by addressing earlier forms of violence and by reducing risks within and across domains of influence. Data were drawn from the Seattle Social Development Project, a longitudinal analysis of more than 800 individuals who were followed from elementary school to young adulthood (age 24). Participants were recruited from 18 Seattle public elementary schools in high-crime neighborhoods. The current analysis focused only on the 644 individuals who were partnered at age 24. The study assessed IPV, youth violence, and the context characteristics of IPV. Data were analyzed using bivariate logistic regression models. Figure, tables, note, references
