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

Indiana University-Purdue University Indianapolis (IUPUI) / Long-term psychosocial consequences of breast cancer are increasingly more important to study as survivors are living longer. However, the survivors do not experience cancer alone; their significant others often suffer just as much if not more than the survivors themselves. In this dissertation, we explore some long-term consequences of cancer within the context of the Social Cognitive Processing Theory (SCPT). SCPT proposes that an individual must be able to discuss their feelings in order to cognitively process a traumatic event, such as cancer. If discussions are hindered, in particular by a significant other, then one will be unable to work through his/her concerns, leading to poor psychological outcomes, such as depression and fear of recurrence. The purpose of this dissertation is to use SCPT to identify causal mechanisms of depressive symptoms and fear of recurrence using a large sample of young breast cancer survivors and their partners. For one paper, we also included a large set of older participants for comparison. This dissertation is divided into three distinct articles. Each article tests long-term consequences of breast cancer and its treatment on breast cancer survivors and their partners using SCPT to explain relationships. First we examine the hypothesized predictors of younger breast cancer survivors’ depressive symptoms including the partner variable of depressive symptoms. The second article addresses the partners by predicting their depressive symptoms using SCPT. The third and final article seeks to identify the relationship of predictors and FOR on both survivors and their partners again using SCPT. For survivors, structural equation modeling analyses found significant direct and indirect paths between depressive symptoms and theoretical variables, including social constraints (stb=.266, p<.001) and intrusive thoughts (stb=.453, p<.001). In partners, cognitive processing variables (intrusive thoughts and cognitive avoidance) mediated the relationship between social constraints and depressive symptoms (F(5,498)= 19.385, R2=.163, p<.001). And finally, cognitive processing mediated the relationship between social constraints and fear of recurrence both for survivors [F(3,213)= 47.541, R2=.401, p<.001] and partners [F(3,215)= 27.917, R2=.280, p<.001). The evidence from these studies supports the use of SCPT in predicting depressive symptoms and fear of recurrence in both long-term survivors and partners.
