Emerging adulthood (ages 18-25 years) is a developmental period marked by changes in attachment, the onset of serious dating relationships, and rates of intimate partner violence (IPV) up to 40% and 90% for physical and psychological IPV, respectively. This dissertation aims to investigate moderators of the link between insecure attachment, a known risk factor for IPV, and psychological IPV, coercive controlling behaviours, and relational aggression in emerging adulthood. One hundred and seventeen undergraduate students in dating relationships were recruited to partake in a baseline assessment followed by a 14-day daily diary study. During the baseline assessment, participants self-reported on putative trait level risk factors such as demographics and insecure attachment. During the daily diary portion, participants reported on their use of partner aggression (physical and psychological IPV, coercive controlling behaviours, and relational aggression; however, due to low base rates, physical IPV could not be analyzed as an outcome), as well as their experiences of felt partner acceptance and rejection, support and conflict in their relationships, alcohol use, and stress for each day. I hypothesized that attachment anxiety, problems in the dyadic relationship (inadequate support, conflict, and felt rejection and anxiety about acceptance), and putative disinhibitors (stress and alcohol consumption) would be directly linked to risk for perpetration of all forms of aggression and interact to predict risk for partner aggression. Hypotheses regarding partner support, conflict, and felt regard were also tested. Specifically, I hypothesized that ratings of partner support fit, hurt as a result of conflict, and daily felt regard would differ for more insecurely attached versus more securely attached individuals. Following application of exclusion criteria, data from 98 participants were analyzed using multilevel modeling in Hierarchical Linear Modeling (Raudenbush et al., 1995). The results from this dissertation underscore the importance of attachment anxiety as an individual risk factor for IPV and identified more proximal risk factors that fluctuate on a daily basis. Attachment anxiety, felt rejection, and conflict were related to risk for all three forms of IPV. Unexpectedly, attachment avoidance was linked to decreased risk for coercive control. Anxiety about acceptance was uniquely associated with risk for psychological IPV, and inadequate support fit was uniquely associated with risk for coercive control. Greater attachment anxiety interacted with high conflict to predict greater risk for coercive control. No other significant two-way interactions between attachment anxiety and problems in the dyadic relationship emerged. Contrary to hypotheses, stress and alcohol consumption were linked to decreased risk for coercive control. Stress also appeared to suppress the link between dyadic problems and risk for psychological IPV on a given day, and dyadic problems paired with alcohol consumption was related to a decreased risk of coercive control. High stress and greater dyadic problems interacted to predict greater risk for coercive control as expected. No conclusions could be drawn about 2-way interactions between stress and dyadic problems and alcohol consumption and dyadic problems when predicting relational aggression, as the model did not converge. This study did not find support for the “perfect storm theory” of aggression (in which a 3-way interaction between risk factors is associated with greatest risk of IPV) when predicting psychological IPV. The “perfect storm theory” could not be tested in relation to coercive control and relational aggression as these models did not converge. The findings from this study contribute to our knowledge of why some people perpetrate IPV and not others, and why people perpetrate IPV on some days and not others. These results inform the multiple possible points of entry for prevention and interventions aiming to promote healthy relationships in emerging adults. / Graduate

Using an attachment theory perspective, variation in adult romantic attachment style outcomes were examined according to childhood experiences of parental divorce and residential instability. The sample was comprised of 172 individuals in the young adulthood developmental stage that were recruited using snowball sampling via online social networking. Participants completed an online survey containing the 36-item Experiences in Close Relationships scale and 28 author-developed items. The majority of the sample reported stable and predictable living arrangements as children. Those whose parents had divorced reported higher levels of parental conflict during their childhood than those whose parents had never divorced or separated. There was no statistical difference on adult romantic attachment style score between individuals who experience parental divorce or separation and those who did not. Parental conflict and stability of residence patterns did not have a statistically significant impact on attachment avoidance or anxiety. For participants whose parents had divorced or separated, conflict, residential stability, and time with nonresidential parent statistically improved the predictive ability of attachment anxiety. Specifically, time with nonresidential parent moderated adult romantic attachment anxiety.

Given the nature of couple conflict, couples are frequently tasked with mutually working towards a solution to a given problem. Effective conflict management is a key relationship resource that maintains closeness and cohesiveness (Epstein & Baucom, 2002; Overall & Simpson, 2013), whereas ineffective conflict management is generally associated with impaired relationship functioning (Gottman & Notarius, 2000; Overall & Fletcher, 2010). The overarching goal of the present thesis therefore consisted of further advancing the field’s understanding of conflict management as an interpersonal process in heterosexual couple relationships. This goal was addressed through two novel and complementary studies. The sample for both studies consisted of 179 community-based heterosexual adult couples involved in a long-term romantic relationship. During the testing session, participants completed a questionnaire package and discussed a topic of disagreement for 15 minutes. These interactions were then coded for both positive and negative conflict management behaviours. Both studies modeled these conflict management behaviours alongside crucial variables involved in couple conflict. The first study examined the ways in which partners’ adult romantic attachment orientations interact to predict their conflict management behaviours. As hypothesized, the results provide preliminary evidence that, in some cases, men’s and women’s conflict management depends on the interaction between their own and their partner’s adult romantic attachment orientation, more so than a sole individual’s attachment. The second study examined whether effective conflict management moderates the negative association between relationship satisfaction and men’s and women’s use of psychological partner aggression. Contrary to hypotheses, the results suggest that, in predicting these aggressive acts, relationship satisfaction and conflict management make fairly independent contributions. These findings are based on strong theoretical frameworks as well as a number of methodological strengths, including the observational coding of positive and negative conflict management behaviours and the implementation of sophisticated dyadic data analyses. Furthermore, by filling gaps in the existing literature, these findings offer several theoretical, empirical, and clinical implications for the field of couple conflict. As individual and collective bodies of work, the studies of the present thesis provide invaluable evidence in support of the complex and interdependent nature of couple relationships. Such findings are highly relevant to couple researchers and clinicians alike, both of whom endeavour to understand and improve couple relationship functioning.

This study examined how adult romantic attachment (anxiety and avoidance dimensions), global self-esteem, and social and academic self-views relate to one another and how well they predict preference for a specific feedback type (enhancing, verifying, or no feedback) from a potential romantic partner in times of distress. It also investigated the relation between the type of feedback one receives and attraction to the partner who gives that type of feedback. Multiple regression analyses supported some predicted relations between romantic attachment and feedback preference. Neither global self-esteem nor social and academic self-views predicted preference for a particular feedback type, nor did social self-views moderate the relation between attachment and feedback preference. Although global self-esteem was found to moderate the relation between attachment style and feedback preference, the moderation effects were not in the predicted directions. However, academic self-views were found to moderate the relation between attachment and feedback preference. In addition, anxious and avoidant attachment related negatively to global self-esteem, social self-views, and academic self-view. Global self-esteem related positively to both social and academic self-views. Receiving one's preferred feedback predicted attraction to the potential romantic partner who gave that type of feedback. Limitations of the study and direction for future research are discussed.

The present study examined the possibility that adult romantic attachment orientation, empathy, and social skills could either individually or jointly influence the expression of mate poaching behaviors. Participants (N = 404) were recruited from a Southern Appalachian university and ranged in age from 18-60 years, with a mean of 21. Data were collected using a web-based survey system. Results of this study lend support to the growing literature demonstrating a link between adult romantic attachment and mate poaching. Additionally, the present study also added to the literature by showing for the first time 1) a relationship between empathy and mate poaching and 2) a relationship between social skills and mate poaching. Contrary to one of the hypothesized structural models, adult attachment was not found to mediate the relationships between 1) empathy and mate poaching and 2) social skills and mate poaching.

The present study explored how emotional cushioning (EC) buffered the relationship between grief intensity of perinatal loss and relationship satisfaction among women who have experienced pregnancy after loss. It was hypothesized that higher levels of grief intensity would be negatively associated with relationship satisfaction among women. Additionally, it was hypothesized that higher levels of EC would lessen the negative relationship between grief intensity of perinatal loss and relationship satisfaction among women. Through the use of a hierarchical linear regression, it was determined that grief intensity was not significantly associated with relationship satisfaction and that EC did not serve as a buffer between grief intensity and relationship satisfaction. However, a significant correlation was found between EC and relationship satisfaction. The results of this study can help contribute to the literature by providing more discussion about utilizing systemic approaches for clients who have experienced perinatal loss and pregnancy-related anxiety.
