This study examined the impact of temporal changes in intimate partner violence (IPV) on individuals' romantic relationship. Analyses based on a sample of 8279 young adults from Waves III and IV of the National Longitudinal Study of Adolescent Health (Add Health) revealed that greater temporal increases in victimization were related to lower satisfaction. The association between increases in perpetration and satisfaction was not significant. Additionally, for women, greater increases in IPV perpetration were related to higher satisfaction. For men, the association between increases in perpetration and satisfaction was not significant. For both men and women, greater increases in victimization were related to lower satisfaction. Thus, temporal changes in IPV might have differing impacts on relationship satisfaction for men versus women.Intimate Partner Violence (IPV), often defined as physical, sexual, or psychological harm by a current or former partner or spouse (Centers for Disease Control and Prevention [CDC] 2013), is prevalent in the United States (O'Leary et al. 1989). Even young couples experience IPV. It is estimated that 16 % to 36 % of newlywed husbands and 24 % to 44 % of newlywed wives have perpetrated physical aggression against their partners (Panuzio and DiLillo 2010). Studies have shown that IPV is related to a variety of negative outcomes, including increased levels of stress (Testa and Leonard 2001), as well as symptoms of depression (Peltzer, Pengpid, McFarlane, and Banyini 2013). One of the strongest correlates of IPV that has received a lot of attention in the academic literature is romantic relationship satisfaction (O'Leary et al. 1989). Not surprisingly, previous research has repeatedly resulted in findings indicating a negative association between IPV and satisfaction (e.g., Panuzio and DiLillo 2010). However, the vast majority of studies on romantic relationships are based primarily on cross-sectional data, which limits interpretation of results and reveals little about how relationships may become more or less satisfying over time (Karney and Bradbury 1995). In addition, since individuals' relationship status, partners, and the nature of the relationship itself can change, it is important to look at changes in rates of relationship aggression and to examine how these changes might effect partners' satisfaction with their current relationships. However, this point has been relatively ignored in the literature. Thus, the purpose of the present study was to examine the impact of changes in rates of IPVover time on individuals' relationship experiences, specifically, on their levels of relationship satisfaction. Lawrence and Bradbury (2007) draw attention to the importance of clarifying the temporal nature of IPV in intimate relationships, reasoning that while evidence of stability would draw attention to between-subjects explanatory factors, such as personality characteristics, evidence of change would draw attention to within-subject or within-marriage explanatory factors, such as stress ...
