Integrative Statement

Intimate partner violence (IPV) often begins during late adolescence and then continues as a behavior pattern during adulthood (Johnson, Giordano, Peggy, & Longmore, 2015). Between 20-36% of late adolescents experience or perpetrate IPV, and more than 50% of reported IPV is co-perpetrated (Langhinrichsen-Rohling, Selwyn, & Rohling, 2012). Thus, it is important to understand the factors that are associated with IPV. The current study examines patterns of IPV perpetration in late adolescent relationships as predicted by the I3 model (Finkel, 2014), a framework used to identify the individual, dyadic, and contextual factors leading to IPV. Late adolescence, the transitional stage between adolescence and adulthood, is the period in which the psychological centrality of romantic relationships develops, compared with the earlier, more exploratory romantic relationships of early and mid-adolescence (Collins, 2003). In addition, late adolescence is also a period of increased responsibility, as individuals in this age group enhance their involvement with complex social, educational, and work settings. The I3 model proposes that IPV perpetration is predicted by a 3-part process: instigation, impellance, and inhibition. Instigating factors include cues from one partner that could trigger aggression in the other partner. Impellance includes person-level factors (i.e., attachmentinsecurity) that reinforce an individual to behave aggressively when faced with perceived provocation. Inhibition refers to factors that mitigate the individual’s tendency to aggress. Conversely, disinhibiting factors (i.e., perceived stress) promote the individual’s tendency to aggress. While the I3 model has typically been used to understand male perpetration of IPV against female partners, this model may provide a framework within which to examineco-perpetration of IPV. 104 heterosexual adolescent couples completed measures of person-level characteristics, including measures of adult romantic attachment insecurity. They then completed daily electronic diaries of their overall stress and experiences with their partners for 28 consecutive days. Intensive longitudinal methods and modeling techniques will be used to obtain an in-depth examination of what leads to co-perpetration of IPV in these dating couples. Preliminary analyses indicated that IPV perpetration differed for men and women, such that women engaged in slightly more violence against their male partners. Multilevel causal process models determined that attachment insecurity, but not gender, moderated the relationship between daily stress and daily perpetration, such that individuals who endorsed high attachment insecurity perpetrated more violence against their partners on days when their levels of stress were also increased. These findings suggest that daily experiences and person-level factors interact to influence the use of violence within relationships. Given these findings, the current study will test the I3 model by examining how daily context of perceived stress and person-level factors (i.e., attachment insecurity, gender, childhood experiences) operate within dyads to predict IPV perpetration.
