The primary objective of this thesis was to investigate the broader consequences of rumination. This entailed exploring the emotional and interpersonal outcomes of rumination at both an individual and dyadic level. A secondary objective was to investigate the unique contribution of attachment to rumination, and the contributing influence of context, with rumination in the confines of a romantic relationship specifically explored. It is proposed that insecure attachment may be both associated with an increased engagement in rumination and a greater likelihood of negative consequences as the result of ruminating. It is also proposed that rumination will not only have consequences for the individual, but that it will also have consequences for their romantic partner. Studies 1 and 2 explored the broader consequences of rumination, and the contribution of attachment, for the individual who is ruminating. Both studies involved student samples. Self-report data from Study 1 confirmed rumination was significantly correlated with depressive symptoms, depressive mood and the negative emotions of shame, guilt and anger. Rumination was also significantly correlated with insecure attachment. Together, rumination and insecure attachment were found to have a unique additive effect on the experience of depressive symptoms, shame and guilt. For depressive mood and anger, insecure attachment was found to moderate the effect of rumination. In Study 2 the relationship among rumination, attachment, negative emotion and interpersonal feelings was investigated experimentally. The contribution of context was also explored with individuals asked to either ruminate or distract after thinking about a negative relationship event. Correlational analyses indicated rumination was significantly associated with greater levels of negative emotion and relationship conflict, and lower levels of relationship depth and support. Experimental results confirmed ruminating on a negative relationship event resulted in lower levels of overall mood than distracting. Ruminating on a negative relationship event (as compared to distracting) did not result in lower levels of relationship satisfaction or relationship closeness, or greater negative feelings about the relationship. Neither anxious-ambivalent nor avoidant attachment significantly contributed to the experience of negative emotion or negative interpersonal feelings when ruminating (versus distracting) on a negative or typical relationship event. Studies 3 and 4 explored the broader consequences of rumination for both the individual and their romantic partner. Study 3 involved a student sample, while Study 4 involved a community sample of adults. All couples were in a heterosexual relationship. Structural Equation Modelling confirmed the presence of emotional and interpersonal consequences of rumination for both samples of individuals. In regards to the consequences of rumination for one’s partner, results for the student sample indicated rumination in males was associated with greater levels of negative emotion but also lower levels of conflict in their partner. Rumination in females was associated with greater negative emotion in the relationship and greater levels of conflict for their partner. For the community sample, rumination in males was associated with greater relationship satisfaction for their partner. Study 5 also explored rumination in the context of a romantic relationship. It did this by investigating the emotional and interpersonal consequences of verbally ruminating with a partner (referred to as co-rumination; Rose, 2002). A within-subjects experimental design was utilised where couples were asked to both co-ruminate, and to reflect together on a negative and a positive relationship event. Results indicated co-ruminating on a negative event resulted in greater relationship closeness and perceptions of support. Results also suggested that females felt they were giving more support to their partner while co-ruminating, while males felt they were giving more support while co-reflecting. No significant effect of co-rumination on emotion was noted. Overall, the current thesis has extended the literature by providing evidence that rumination has several broader consequences beyond its established relationship with depression. Specifically, it has been shown here that rumination not only affects an individual’s emotions but that it also influences their interpersonal feelings. A deeper understanding of the complexities of rumination has also been provided with results highlighting the importance of the content of ruminative thought and the internalised nature of rumination. In regards to contributors to rumination, results have increased our understanding of the role of insecure attachment in contributing to the tendency to ruminate and to the relationship between rumination, emotion and interpersonal feelings. Results have also highlighted the importance of context with rumination associated with emotional and interpersonal consequences both for the individual who is ruminating and for their romantic partner. The implications of these findings and directions for future research are discussed in depth throughout this thesis.

Co-rumination involves friends spending a great deal of time encouraging each other to excessively discuss problems, with content being largely negative (Rose, 2002). Co-rumination appears to strengthen the bonds between best friends, while ironically exacerbating internalizing symptoms. Co-rumination is conceptualized as a mutual dyadic process, but little is known about the reciprocity of excessive problem discussion. The balance of college students' (N = 601) self- and other-focused co-rumination with their best friend was assessed via an online survey. Contrary to expectations, inconsistent and weak evidence was obtained for differentiating self- and other-focused co-rumination, and their balance. Specifically, self- and other-focused co-rumination were highly correlated, similarly correlated with other study variables, and not differentiated in exploratory factor analysis. However, the interaction of self- and other-focused co-rumination in a model including individual characteristics and adjustment yielded differentiated results. Friendship intimacy was associated with self-, but not other-, focused co-rumination. Indicating that balance may matter, anxiety was associated with high self-focused co-rumination in the context of low other-focused co-rumination. Additionally, mean levels of all individual traits (rumination, excessive reassurance seeking, social perspective taking, perfectionism, negative problem orientation) and adjustment variables (anxiety, depression, social anxiety, friendship quality) differed as a function of co-rumination balance, as assessed by a one-item direct measure. The validity and utility of distinguishing self- and other-focused co-rumination is contingent on further exploration with dyadic data and perhaps modified assessment. Rumination and excessive reassurance seeking indicated vulnerability for co-rumination, which appears to be a primarily anxious process.

Children with co-occurring internalizing and externalizing problems (MIXED children) represent a distinct aggressive subtype with negative outcomes; understanding what works for them in treatment is imperative. The success of MIXED children in some family-based programs for aggression may be attributable to collateral reductions in internalizing symptoms. The current study examined whether reductions in internalizing behaviour in MIXED children were due to reductions in maternal depression and parent-child co-rumination. Co-rumination, a dyadic interaction related to internalizing symptoms, is defined as excessively discussing problems and dwelling on negative feelings. We investigated 154 MIXED children and 49 pure externalizers who underwent Parent Management Training/Cognitive Behavioural Therapy. Mother-child co-rumination was assessed using videotaped observations of problem discussions gathered at pre-treatment, post-treatment and follow-up. We hypothesized that, at pre-treatment, mother-child co-rumination would mediate the relation between maternal depression and child internalizing problems. During treatment, we expected that co-rumination and maternal depression would predict reductions in child symptoms. Finally, we hypothesized that reductions in co-rumination would mediate the association between improvements in maternal depression and improvements in child internalizing which would, in turn, impact externalizing outcomes. Results did not support our pre-treatment and during treatment hypotheses about the role of co-rumination as a mediator. At pre-treatment, maternal depression was associated with child internalizing problems and co-rumination; co-rumination was not associated with internalizing when controlling for maternal depression. Reductions in maternal depression were associated with improvements in child internalizing and, marginally, with child externalizing, thus partially supporting our hypotheses. We also found that reductions in co-rumination impacted child externalizing, but not internalizing behaviour, again partially supporting our hypotheses regarding co-rumination changes and child symptom changes. Finally, results demonstrated that internalizing improvements affected externalizing outcomes, partially supporting our treatment-related hypothesis. Findings have implications for understanding the development and treatment of problems in MIXED children.

abstract: ABSTRACT This study examines the ways in which employees experience moral emotions that violate employee treatment and how employees co-construct moral emotions and subsequent expressions of dissent. This qualitative study consisted of 123 full-time employees and utilized open-coding, content analysis, constant comparison analysis, and concept mapping. The analysis revealed that employees expressed dissent laterally as a series of sensemaking processes, such as validation of feelings, moral assessments, and assessing the fear of moral transgressions. Employees also expressed dissent as a series of risk assessments that overlapped with the ways in which employees made sense of the perceived infraction. Employees' lateral dissent expression manifested as a form of social support which occasionally led to co-rumination. Employees expressed dissent upwardly when seeking a desired action or change. Circumvention was utilized as a direct reflection to the type and degree of moral transgression related to the person responsible for the mistreatment. Results indicated that experiencing moral emotions that led to expressing dissent with a designated audience was determined by where employees were situated in the cyclical model of communicating moral emotions and in relation to the co-construction of both the infraction related to employee mistreatment and the experience of moral emotions. Results contribute to the existing body of literature on dissent and emotions. A discussion synthesizing the findings and analysis is presented, in addition to the implications for future research.

Co-rumination is a nuanced emotion socialization process that occurs with parents and friends during adolescence. Although co-ruminating builds closeness with others, it corresponds to increased internalizing symptoms, particularly for adolescent girls. The present study explored how specific features of co-rumination vary by relational context (parents, friends) and adolescent gender. These features were also examined in relation to adolescent internalizing symptoms, with adolescent gender as a potential moderator. Thirty adolescents (13–18 years old; 60% female, 40% male) participated in separate discourse tasks with their parent and their same-gender close friend. Co-rumination was observed during these conversations, and adolescents reported their internalizing symptoms. Features of co-rumination varied by relational context and adolescent gender, with unique links to adolescent internalizing symptoms. This study extends prior research by providing a fine-grained analysis of how co-rumination corresponds to internalizing symptoms across two relational contexts.

People turn to others for help and advice during hard times. Early psychologists suggested a ‘talking cure’ as a remedy for emotional turmoil (e.g., Freud, 1916–7/1963; Rogers, 1942). Likewise, folk psychology often sees heart-to-heart conversations as a win-win proposition that brings relief to the afflicted person and reinforces social bonds at the time of need. However, talking about problems does not always help (e.g., Rimé, 2009; Rimé, Mesquita, Boca, & Philppot, 1991; Rimé, Philippot, Boca, & Mesquita, 1992; Rose, 2002). In some cases, problem-talk can be a lose-lose proposition that drags both discussants into depression (Rose, 2002; Rose, Carlson, & Waller, 2007). This thesis examines co-rumination (Rose, 2002), a case of emotional sharing that hurts people instead of helping them, on three levels of analysis (individuals, dyads, and groups). At the individual level, I sketch the life course of co-rumination and replicate earlier findings of gender differences. Furthermore, online survey data (N = 464) links co-rumination with agreeableness and neuroticism. I also demonstrate that co-rumination can be assessed with a brief measure that is 66% shorter than the original. At the dyadic level, data from recorded conversations between romantic couples show that face-to-face co-rumination influences people’s real-time emotional trajectories in complex ways. Furthermore, observer-ratings of the conversations suggest that third-parties can detect co-rumination, even from silent videos. Finally, I study how people react to others’ negative mood and co-rumination in a real social context by longitudinally following two cohorts of students and modelling their interactions with social network analysis tools. These models show that co-rumination appears to elicit social rejection from others, implying a possible pathway to depression via loneliness imposed on the co-ruminators.

Co-rumination is a communication process that has been linked to depressive symptoms among adolescents. The first aim of this study was to examine the directionality of the associations, regarding co-rumination with peers and mothers, as well as comparing co-rumination about the mothers’ and the adolescents’ problems. The second aim was to investigate if gender moderates the associations between co-rumination with peers and depressive symptoms. We used self-report data from two measurement points with a one year interval from the 5-year longitudinal “Three City Study”. Participants were pupils aged 15-17 years at the first measurement point (n = 2,914) and mothers to a subset of the adolescents (n = 44). The results showed that co-rumination with peers was associated with increases in depressive symptoms. Depressive symptoms were associated with decreases in co-rumination with mothers about the mothers’ problems. Preliminary analyses showed that co-rumination with mothers about the mothers’ problems was correlated with co-ruminating about adolescents’ problems. The findings support the notion that co-rumination, especially with friends, is related to depressive symptoms among youth. This, as well as the ways in which mothers communicate with their adolescents, might be important to consider when discussing interventions for adolescents’ depressive symptoms.
