Population-specific data on factors that affect intimate partner violence (IPV) are needed on female adolescents and young adults, a cohort at greatest risk of IPV in the United States (Rennison, 2001). Studies have frequently overlooked the role of relationship communication as a gatekeeper to IPV (Ridley & Feldman, 2003). To address this gap, negative binomial regression was conducted with data from a 2004 survey of 618 women aged 15 to 24 seeking care at an urban reproductive health facility. Findings suggest that, within the previous year, verbal aggression by either partner was associated with physical violence by either or both partners, and verbal reasoning was negatively correlated with physical violence. Bidirectional and unidirectional IPV relationships may employ communication strategies differently. (Contains 4 tables.)
