Clark describes the risks and correlates of intimate partner violence (IPV) among adolescents. Using longitudinal data, she finds that the victim-offender overlap that exists in general violence extends to IPV. Also, Michael Johnson's typology of IPV among adults likely exists among adolescents; sometimes IPV is perpetrated by both partners, and sometimes it is perpetrated by only one. Moreover, IPV victimization is not evenly distributed among adolescents, and more targeted interventions are likely needed to prevent abuse. Clark integrates multiple theories of violence and victimization, including lifestyle exposure theory, differential association theory, general strain theory.
