Physiological synchrony in supportive discussions: An examination of co-rumination, relationship type, and heterogeneity.

During times of stress, we look to close others for support. Social support conversations are critical for relationship maintenance and well-being. Yet, certain ways of talking about problems-such as co-ruminating-can exacerbate stress. Since social support and co-rumination are both dyadic processes, it is important to examine physiological responses during these conversations in a dyadic manner. Little research has examined physiological synchrony of the sympathetic nervous system (SNS) during social support conversations or co-ruminative conversations. The current research capitalizes on an experimental manipulation of co-rumination using a sample of close friends (147 dyads) and romantic partners (113 dyads) to examine physiological covariation in the context of support. Across both samples, dyads exhibited significant physiological covariation in pre-ejection period reactivity (PEP). Contrary to our hypothesis, dyads in the co-rumination condition did not show more covariation. Close friend dyads did, however, exhibit more covariation as compared to romantic dyads. We also found significant variability in physiological covariation across dyads, with a minority of dyads exhibiting negative covariation of PEP reactivity. The homogeneity of the samples limits the generalizability of the findings and highlights the need for more diverse samples in future work. These findings underline the need for further exploration into the mechanisms that contribute to distinct patterns of physiological synchrony, the conditions in which negative synchrony occurs, and what predicts especially strong positive synchrony. This work extends our understanding of physiological synchrony of the sympathetic nervous system during support conversations and emphasizes the importance of considering heterogeneity in physiological processes.

Communication modality matters: Co-rumination via in-person versus digital modalities has different prospective associations with depression and friendship quality.

INTRODUCTION: Co-rumination is an interpersonal emotion regulation strategy in which negative feelings and problems are discussed perseveratively with another person. Although co-rumination is salient in adolescence, research to date has focused on co-rumination occurring in person and has not kept pace with the surge in digital communication that begins in adolescence. This study examined the degree, associations among, and consequences (i.e., depressive symptoms, and friendship quality) of adolescents' co-rumination via in-person, text, social media, and phone modalities. METHODS: Adolescents (n = 109; 51 girls, 57 boys, 1 nonbinary; Mage = 12.83 years) residing in Canada, completed self-report questionnaires on co-rumination, depressive symptoms, and friendship quality for up to 2 years. RESULTS: Adolescents engaged in co-rumination across all modalities, particularly in-person. Findings indicated a negative association between in-person co-rumination at baseline and in-person co-rumination over time. Whereas less text co-rumination was associated with increased depressive symptoms over time, greater phone co-rumination was associated with increased depressive symptoms over time. Although greater in-person co-rumination was positively associated with friendship quality concurrently, it was negatively associated with friendship quality prospectively. CONCLUSIONS: Taken together, co-rumination outcomes may vary depending on communication modality. Implications for adolescents' mental and social wellbeing are discussed.

Adolescent Females' Dyadic Conversations About Body, Weight, and Appearance.

Body talk among adolescent females has been associated with negative outcomes, including depressed mood, disordered eating, and body dissatisfaction. Yet, little work has investigated the manifestation of body talk in actual conversations between adolescent females or explored pathways through which body talk is spread (e.g., co-rumination). The present study examined body talk among adolescent female dyads (N = 23 dyads) ages 13 to 17 (Mage = 15.12) using an observational design. Reciprocally nominated dyads were recruited from a high school in the southeastern United States. Conversations between dyads were qualitatively coded using an applied thematic analysis approach. Identified themes were related to weight, appearance, and personality. Results provide insight into the social context in which sociocultural norms of weight stigma, body dissatisfaction, and eating-related psychopathology may be reinforced. Findings have implications for informing the development of interventions to reduce co-rumination of negative weight- and appearance-related body talk and to promote positive body image and healthy weight among adolescent girls.

The trade-offs of co-ruminating with friends: A profile analysis.

Adolescents' co-ruminating with friends has been tied to trade-offs: having higher quality friendships but experiencing more depressive symptoms. To determine if individual youth experience these trade-offs, we applied a person-centered approach to Swedish adolescents' self-reports of co-rumination with friends, depressive symptoms, and friend support (n = 2767, aged 12-16, 52% girls; 88% Swedish). We found four latent profiles: Two high in co-rumination and two low. One high co-rumination profile exhibited the proposed trade-offs; the other reported high friendship support and fewer depressive symptoms. Comparisons indicated that the trade-offs profile were primarily girls and exhibited comparatively more difficulties with stress regulation, conceptions of their parents and themselves, and relations with peers. Focusing on the complexity of co-rumination could reveal further nuances.

Social interaction matters to job search over the long haul.

Based on social cognitive, reasoned action, and basic needs theories, this study examines whether co-rumination with others about the job search mediates the positive relation between state negative affect and job search intentions. In addition, we looked at how this positive indirect effect interacts with the social support received from different sources (such as friends, family, and significant others) at the beginning and six months after the initial job search process. Using a sample of 87 graduates (job seekers) from a Portuguese masters program, we used multilevel modeling to test this moderated mediation. Ages ranged from 22 to 53 years old (M = 29.45; SD = 7.60). Data were collected using measures to assess negative affect, co-rumination, perceived social support, and job search intentions. We found an indirect effect of state negative affect on job search intentions; when job seekers perceive higher levels of social support from significant others at the beginning of the job search, the positive, mediating role of co-rumination in this relationship is increased. Further, for a sub-sample of six-month job seekers, this positive indirect effect increased when there was also an increased perception of social support from family. Discussion focuses on implications for theory and practice and the role of co-rumination for unemployed people during job search.

Adolescent girls' intrapersonal and interpersonal parasympathetic regulation during peer support is moderated by trait and state co-rumination.

Effective emotion regulation (ER) is integral to adolescents' mental well-being and socioemotional development. During adolescence, peer interactions have an increasingly salient influence on the development of effective ER, but not all supportive peer interactions support adaptive ER. Co-rumination reflects the tendency to seek ER support by engaging with peers in negatively focused discussion of ongoing problems. We examined associations between co-rumination (state and trait) with measures of individual's autonomic (i.e., respiratory sinus arrhythmia, RSA) and affective regulation (self-report) among 30 female close-friend dyads (ages 11-17; 74% White) while engaged in a support-seeking discussion in the laboratory. We found that trait co-rumination corresponded with RSA withdrawal during peer support, suggesting a potential mechanism by which co-rumination contributes to dysregulated ER. We also examined dyadic patterns of physiological regulation via prospective change actor partner interdependence models (APIM). Partner effects were moderated by behaviorally coded state co-rumination. Dyads with high state co-rumination displayed coupled RSA movement in opposite directions, while dyads with low state co-rumination exhibited coupled RSA movement in the same direction. These findings are consistent with similar physiologic linkages in close relationships observed in other developmental periods. Results highlight the importance of multimodal assessment for characterizing social ER processes across development.

Within-person Changes in Co-rumination and Rumination in Adolescence: Examining Heterogeneity and the Moderating Roles of Gender and Time.

Although previous work has consistently identified positive associations between co-rumination and rumination during adolescence, little to no research has examined how this relationship operates on the person-specific level. The current study aimed to extend current developmental theories of co-rumination and rumination by examining within-person associations between these constructs. Survey data was collected from 1502 adolescents (Mage = 13.20; 52% girls; 52% non-Hispanic White) every six-months across the span of 3.5 years. The results showed that at time-points when adolescents reported co-ruminating more than their usual level, they reported concurrent increases in rumination. This association was stronger for boys and strengthened over time. Despite substantial between-person heterogeneity, 97% of adolescents showed positive associations between co-rumination and rumination. This research has important implications for mental health professionals, school systems, and parents who may look to teach adolescents about effective emotion-regulation.

Co-rumination across in-person and digital communication: Associations with affect and relationship closeness in adolescents.

INTRODUCTION: Despite the prominence of interpersonal emotion regulation, particularly during adolescence, it is a relatively understudied area of investigation. Co-rumination is an interpersonal emotion regulation strategy that is frequently used by adolescents. Traditional examinations of co-rumination have focused on its occurrence in person, while largely overlooking digital modes of communication. This study was the first to investigate adolescents' co-rumination across multiple communication modalities (i.e., in person, text, social media, phone) and its downstream association with affect and relationship closeness. Specifically, we examined: (1) the frequency of co-rumination across modalities, (2) the effect of co-rumination in one modality on the future use of co-rumination within that same modality (i.e., stability) and across other modalities (i.e., generalization); and (3) the prospective relation of co-rumination on negative affect, positive affect, and relationship closeness. METHODS: Adolescents (n = 71; 33 girls and 38 boys; Mage = 12.70 years) residing in Canada completed twice-daily diary surveys for 14 days. RESULTS: Findings indicated that adolescents co-ruminate across all modes of communication, particularly in person. There also was evidence of co-rumination stability and generalization over time for some modes of communication (within phone and from social media to in-person interactions), but not for others. Co-rumination through text and over the phone had affective and/or social benefits, whereas co-rumination through social media predicted diminished positive affect. We also identified ways these findings differed by gender. CONCLUSIONS: Implications for adolescents' emotional and social development and the field of co-rumination are discussed.

Co-Rumination and Depressive Symptoms in Adolescence: Prospective Associations and the Mediating Role of Brooding Rumination.

Although relationships between co-rumination and depressive symptoms have often been found, little research attention has been given to mechanisms underlying this association. The current study investigated brooding rumination as a mediator of the relationship between co-rumination and depressive symptoms. Analyses were performed on data of 1549 adolescents (53.4% girls; Mage = 12.93, range 9-17) using three waves of data with 1-year intervals. Mediated and indirect effects were investigated by means of cross-lagged analyses. The results indicated that co-rumination was not predictive of depressive symptoms 2 years later. However, co-rumination did have an indirect effect on prospective depressive symptoms through brooding rumination. Additional analyses looking into the directionality of effects showed that neither brooding rumination nor depressive symptoms were predictive of relative increases in one's tendency to co-ruminate. Multi-group analyses further showed that findings were not moderated by gender or age. The current study contributes to the growing literature on the role of interpersonal and intrapersonal affect-regulation styles in predicting depressive symptoms and suggests that passive and catastrophic problem talk with same-sex friends may get internalized into maladaptive and repetitive thinking patterns.

Parent-Adolescent Communication Influences on Anxious and Depressive Symptoms in Early Adolescence.

The unique developmental changes and important role of parents during early adolescence warrants consideration of parent-adolescent communication, including open communication, co-problem-solving, and co-rumination, and its influences on adolescents' anxious and depressive symptoms. In this study, 400 early adolescents (M age = 12.49; 54% female) recruited from a middle school completed electronic questionnaires at two time points, 5 months apart. While most bivariate associations examined between communication processes and adolescents' symptoms were significant, path analyses found unique patterns. Specifically, over time, paternal open communication was negatively associated with adolescent anxious and depressive symptoms while paternal co-rumination was positively associated with depressive, but not anxious, symptoms. In contrast, few maternal communication factors were significantly linked to adolescents' internalizing symptoms, with only maternal co-rumination surprisingly being negatively linked to depressive symptoms over time. The results suggest how parents communicate with their children may be important as early adolescents develop problem-solving and adaptive coping skills to successfully navigate new experiences.

Talking Together, Thinking Alone: Relations among Co-Rumination, Peer Relationships, and Rumination.

Girls are more likely to engage in rumination, associated with the development of mental health problems, as well as report higher levels of friendship quality, hypothesized to protect against these disorders. The current study examined whether co-rumination may drive simultaneous increases in rumination and changes in friendship quality among adolescents. The project included 360 participants (43% boys), ages 9.8 to 15.8 years, and analyses revealed that co-rumination mediated the link between female sex and both rumination and negative friendship quality. There was also a bidirectional relation between co-rumination and positive friendship quality. These findings highlight several pathways by which co-rumination mediates the relation between sex and both maladaptive (i.e. rumination, negative friendship quality) and adaptive (i.e. positive friendship quality) outcomes.

Co-Brooding and Co-Reflection as Differential Predictors of Depressive Symptoms and Friendship Quality in Adolescents: Investigating the Moderating Role of Gender.

Co-rumination has been shown advantageous for friendship quality, but disadvantageous for mental health. Recently, two components have been distinguished, with co-brooding predicting increases in depressive symptoms and co-reflection decreases. The current study aimed to replicate these findings and investigated whether both components also show differential relations with friendship quality. Gender was investigated as a moderator. Path analyses were used on data of 313 adolescents aged 9-17 (50.5% girls). Co-brooding was related to more concurrent and prospective depressive symptoms in girls. Co-reflection predicted less concurrent and prospective depressive symptoms in girls and higher concurrent positive friendship quality for boys and girls. This study underscores the value of studying co-rumination components and suggests that boys and girls in this context differ in their pathways towards depression.

The Relationship between Co-rumination and Internalizing Problems: A Systematic Review and Meta-analysis.

Co-rumination refers to the process of engaging in repeated discussion of personal problems in dyadic relationships. The current systematic review and meta-analysis provided an evaluation of the relationship between co-rumination and internalizing problems in children, adolescents and young adults, along with an investigation of potential moderator variables. Studies were eligible for inclusion if they quantitatively assessed the relationship between co-rumination and depression, anxiety and/or internalizing problems using validated measures. An electronic search was conducted in PsycINFO, PsycARTICLES, Medline, Scopus and the Cochrane Library database of systematic reviews for studies published since 2002. In addition, unpublished studies were located by contacting authors in the field and by online searches of dissertation databases. Thirty-eight studies were deemed eligible for inclusion comprising a total of 12 829 community-based participants. A random-effects model was employed in the analysis, and effect sizes were obtained exclusively from cross-sectional data. Small to moderate effect sizes were found across four outcomes representing internalizing problems (mean corrected correlation range 0.14 to 0.26), with no significant variability across these variables. Female participants were found to score significantly higher on measures of co-rumination compared with males (d = -0.55). Moderator analyses revealed mixed findings. No significant effects were found for age, gender or publication status. A significant effect was found for co-rumination questionnaire version used (p = 0.05), and a marginal effect found for co-rumination partner (same-sex best friend versus other confidants; p = 0.08). These findings indicate that co-rumination may have a modest but significant association with internalizing problems. The implications of these findings and directions for further research are discussed. Copyright © 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Co-rumination has maladaptive (repetitive, unproductive discussion of problems) components, but also shows an association with friendship satisfaction. The current review found that co-rumination has small-moderate association with depression and anxiety. Practitioners should be aware of the way in which people discuss affective distress with others.

Adolescents' co-rumination and stress predict affective changes in a daily-diary paradigm.

Co-rumination has been related to both high quality friendship and depressive symptoms. However, little is known regarding the extent to which co-rumination may be detrimental, its distinction from rumination and potential gender differences in co-rumination. This study used a modified version of Rose's Co-rumination Questionnaire (Rose, 2002) to examine the behaviour of daily co-rumination with daily stress and negative affect among adolescents. Results demonstrated that co-rumination did not have a main effect in predicting negative affect, but did evidence a significant interaction with life stress. Additionally, co-rumination demonstrated incremental utility above that of rumination. Finally, gender differences were not supported. In conclusion, this investigation revealed that co-rumination exacerbates the effects of life stress and is predictive of increased internalising symptoms.

Clicking away at co-rumination: co-rumination correlates across different modalities of communication.

Co-rumination is associated with positive friendship quality (thought to buffer against anxiety and depression) but paradoxically higher levels of anxiety and depression. With the increasing use of technology for communication among adults, there is little known about co-rumination effects across different modalities of communication. In the current study, we examined co-rumination through four methods (i.e. in person, phone calls, text messaging, and social media) in two separate samples - college students and participants from the community. Classic co-rumination effects were found for in-person communications, and we found that co-rumination by telephone as well as by texting, for a college student sample only, mirrors some of these findings for in-person co-rumination. In studies of co-rumination, evaluation of multiple modes of communication is warranted.

Relationship Quality Buffers Association Between Co-rumination and Depressive Symptoms Among First Year College Students.

Co-rumination, the tendency to dwell on negative events and feelings with a relationship partner, is an aspect of relationships that has been associated with socioemotional adjustment tradeoffs and is found to be associated with depressive symptoms. However, depending on the context in which it occurs, co-rumination is not necessarily associated with detriments to mental well-being. Differences in relationship quality within certain relationships may explain why co-rumination is not always associated with depressive symptoms. In the current study, we utilized self-report measures in an ethnically diverse sample (53.5 % non-White) of 307 first term college students (65 % female) in order to elucidate how co-rumination between roommates may be associated with depressive symptoms. We found that the association between co-rumination and depressive symptoms was moderated by relationship quality such that co-rumination in a high quality relationship was not associated with depressive symptoms whereas the opposite was true in low quality relationships. Moreover, we found moderated mediation, such that the variance in the association between co-rumination and depressive symptoms was explained via self-esteem, but only for those co-ruminating within a low quality relationship. These results suggest that relationship quality may impact the extent to which co-rumination is associated with depressive symptoms among first year college students.

Is co-ruminating with friends related to health problems in victimized adolescents?

Co-rumination, or the tendency to revisit and endlessly discuss problems and negative events, has been linked to depression and other emotional difficulties (Rose, Carson, & Waller, 2007). The current study examined the moderating effect of co-rumination on the relationship between peer victimization and depression, anxiety, PTSD symptoms, and health problems in 108 adolescents aged 10-15 years. Adolescents and a parent completed measures of adolescents' peer victimization, co-rumination, depression, and health problems. Results indicate that adolescents who are both peer victimized and engaged in high levels of co-rumination were at highest risk for psychological problems. Co-rumination also moderated the relationship between peer victimization and physical health problems via general depressive symptoms (i.e., moderated mediation).

Brief report: preliminary evidence that co-rumination fosters adolescents' depression risk by increasing rumination.

Mounting research shows that the tendency to co-ruminate with peers regarding ongoing problems increases adolescents' depression risk; however, the means by which this interpersonal process fosters risk has not been identified. This said, theorists have proposed that co-rumination increases depression risk, in part, by increasing one's tendency to ruminate when alone. We tested this hypothesis in a study of 201 high-school freshmen who completed two assessments, six months apart. Supporting the proposed model, co-rumination predicted prospective increases in rumination and rumination predicted increases in depressive symptoms. The direct effect of co-rumination on depressive symptom change was not significant. Results indicate that co-rumination with friends may serve to increase rumination, which in turn increases depression risk.

Co-rumination via cellphone moderates the association of perceived interpersonal stress and psychosocial well-being in emerging adults.

Adolescents' and emerging adults' social interactions increasingly revolve around cellphone use, but little research has investigated the psychological properties of cellphone interactions. The current study explored co-rumination via cellphone; that is, the use of cellphone functions to excessively communicate about problems or negative feelings. Face-to-face co-rumination and co-rumination via cellphone were examined as potential moderators of the association between perceived interpersonal stress and psychosocial well-being (i.e., positive mental health and social burnout) in a sample of 142 college students. Face-to-face co-rumination was not a moderator. However, co-rumination via cellphone was a significant moderator such that higher levels of perceived interpersonal stress were associated with lower levels of well-being only among college students who reported higher levels of co-rumination via cellphone. Co-rumination via cellphone should be further investigated to elucidate its developmental trajectory and mental health correlates.

When Support Seeking Backfires: Co-Rumination, Excessive Reassurance Seeking, and Depressed Mood in the Daily Lives of Young Adults.

Research has linked depression to maladaptive variants of support seeking, including co-rumination (CR) and excessive reassurance seeking (ERS), which may contribute to symptom onset and maintenance. Although both CR and ERS are associated with depression, insufficient research has examined how daily behaviors and experiences interact with trait-level CR and ERS to predict daily mood. Fifty-one undergraduates, over-selected for internalizing symptoms, completed baseline assessments, followed by a 14-day daily diary assessing behaviors, stressors, and mood. Daily problem-related talk was associated with elevations in depressed mood for participants with high (but not low) trait CR, particularly for those with major depression. Trait ERS similarly moderated the association between daily reassurance seeking and depressed mood. CR, ERS, and daily reassurance seeking each predicted greater affective reactivity to daily stressors. Results align with daily processes hypothesized by CR and ERS models, and suggest that both constructs may be best understood within a diathesis-stress framework.
