abstract: Criminologists have directed significant theoretical and empirical attention toward the institution of marriage over the past two decades. Importantly, the momentum guiding this line of research has increased despite the fact that people are getting married far less often and much later in the life course than in any point in American history. The aim of this dissertation is to address this disconnect by focusing attention to nonmarital romantic relationships and their instability during emerging adulthood. To do so, it uses data from the Pathways to Desistance Study, a longitudinal study of 1,354 at-risk males and females who were adjudicated from the juvenile and adult systems in Phoenix and Philadelphia between 2000 and 2003. The project focuses attention to the following issues: (1) the effect of romantic dissolution on aggressive and income-based offenses; (2) the extent to which strain/negative emotionality and peer influence/exposure account for the effect of romantic dissolution on crime; and (3) the extent to which certain relationship and individual circumstances moderate the effect of romantic dissolution. The models reveal a few key findings. First, romantic dissolution is strongly related to an increase in both aggressive and income-based crime, but is more strongly related to income-based crime. Second, the effect of romantic dissolution is reduced when measures of strain/negative emotionality and peer influence/exposure measures are added to models, but the peer influence/exposure measures account for the strongest reduction. Finally, romantic dissolution does not serve as a positive life event among these at-risk youth, but its effect is exacerbated under a number of contexts (e.g. when an individual is unemployed). This study closes with a summary of these findings as well as its key limitations, and offers insight into potential policy implications and avenues of future research. / Dissertation/Thesis / Ph.D. Criminology and Criminal Justice 2013

Many people experience a romantic breakup at some point in their lives, but people's reactions can vary considerably. A common way of coping with the dissolution of a romantic relationship is to seek support and opportunities to talk with close others. Although talking with social network members may prove helpful for some, the Social-Cognitive Processing (SCP) model posits that interpersonal interactions can hinder emotional recovery and adjustment if the disclosers feel the social network members are responding in a socially constraining way. As a result of perceiving social constraints, individuals may try to avoid thinking and talking about the breakup altogether, which, in turn, may interfere with the cognitive processing necessary to move forward from the breakup. The current research marked the first time the SCP model was explored with regards to the dissolution of romantic relationships, and it evaluated the utility of the SCP model in potentially explaining the variable nature of adjustment to a romantic breakup. One hundred and seventy-four eligible participants completed this online study. Participants completed various questionnaires pertaining to their previous relationship and subsequent breakup, their feelings and experiences following the romantic dissolution, their tendencies to think about the breakup, and the degree to which they discussed the relationship dissolution with others and the reactions they received during these conversations. In support of the SCP model, the results indicated that social constraints were associated with greater psychological distress. Furthermore, avoidance partially mediated the relation between social constraints and psychological distress as levels of social support decreased. This suggests that higher levels of social support might help buffer against engaging in avoidance in response to social constraints. In an initial attempt to examine whether the extent of avoidance displayed varied as a function of a dispositional variable (i.e., self-monitoring), no support was found. Future research should continue to investigate additional factors that may moderate the relation between social constraints and psychological distress through avoidance. / Psychology
