Substance Use as a Risk Factor for Intimate Partner Violence Overlap: Generational Differences Among Hispanic Young Adults.

Intimate partner violence (IPV) research often focuses on either the victims of IPV or the perpetrators of IPV. Recent studies have documented the existence of a group of victim-perpetrators, for example, they perpetrate IPV and are also the victims of IPV. The current study examines this overlap in IPV perpetration and victimization among a nationally representative, longitudinal sample of 1,488 Hispanics with a focus on generational status. Results from group-based trajectory models and survey multinomial regression techniques suggest that alcohol and marijuana use over time are salient risk factors for IPV perpetration, IPV victimization, and IPV overlap. Study limitations and implications are discussed.
