Co-Rumination Moderates the Relation between Emotional Competencies and Depressive Symptoms in Adolescents: a Longitudinal Examination

The complex relationship between NSSI exposure and suicidal risk: Insights from a short-term longitudinal study

OBJECTIVE

Adolescent suicide has become a critical global public health issue. While non-suicidal self-injury (NSSI) is closely associated with suicide, the role of NSSI exposure remains unclear. This study aims to explore possible mechanisms among NSSI exposure, NSSI engagement, and future suicidal risk.

METHOD

A total of 2,155 Chinese middle school students (47.9 % girls; M = 13.38 years, SD = 0.66) participated in the study. During the first survey, they reported demographic information, NSSI exposure, and NSSI engagement. Three months later, they completed follow-up assessments on suicidal risk and depressive symptoms.

RESULTS

Our results revealed three distinct relational patterns between NSSI exposure, NSSI engagement, and future suicidal risk: (1) NSSI exposure is associated with future suicidal risk through the mediating role of NSSI engagement (indirect effect = 0.145, SE = 0.02, 95 % CI [0.107, 0.183]); (2) NSSI exposure independently impact suicidal risk without NSSI engagement (β = 0.046, SE = 0.018, t = 2.299, p < 0.05); (3) NSSI exposure amplifies the predictive effect of NSSI engagement (β = 0.053, SE = 0.014, t = 3.844, p < 0.001, 95 % CI [0.023, 0.010]).

CONCLUSIONS

Our findings highlight the importance of interpersonal exposure, rather than media exposure, in these pathways. This study uncovers multiple pathways through which NSSI exposure influences suicidal risk, offering preliminary evidence for targeted prevention strategies.

Co-Rumination as a Moderator Between Best-Friend Support and Adolescent Psychological Distress

INTRODUCTION

Co-rumination, characterized by excessively discussing problems and dwelling on negative affect within a dyadic friendship, has been associated with adolescents' symptoms of depression, anxiety and perceived stress-collectively referred to as psychological distress. This study explored whether co-rumination moderates the association between perceived best friend support and psychological distress.

METHODS

The study included 187 adolescents (52.9% girls; 88.0% Dutch ethnic background) recruited from two cohorts between March 2017 and July 2019. Assessments took place at two time points: symptoms of depression, anxiety, and perceived stress were assessed via self-report measures at the final grade of primary school (T1; Mage = 11.8 years) and in secondary school (T2; Mage = 13.3 years). Co-rumination and perceived best friend support were measured via self-report in secondary school.

RESULTS

Findings indicate that best friend support was associated with lower psychological distress and conversely, co-rumination was associated with higher psychological distress while adjusting for prior distress symptoms. Moderation analysis revealed that moderate levels of co-rumination (relative to the samples mean) decreased the positive effects of perceived best friend support on symptoms of depression (B = 0.06, SE = 0.03, 95% CI [0.00, 0.11], p = 0.05, β = 0.11) and perceived stress (B = 0.06, SE = 0.01, 95% CI [0.03, 0.08], p = 0.000, β = 0.10). At very high levels of co-rumination (relative to the samples mean), best friend support exacerbates perceived stress.

DISCUSSION

This study underscores the potential negative impact of co-rumination in supportive peer relationships and recommends promoting awareness of the risk of co-rumination while building a repertoire of (dyadic)emotion regulation strategies.

The Relationship Between Co-rumination and Depressive Symptoms: A Systematic Review and Meta-Analysis

Numerous studies have explored the link between co-rumination and depressive symptoms, but a consensus remains elusive. This study proposes a dual-pathway model to explain this relationship through a "positive path" (adaptive response) and a "negative path" (distress response). It also conducts a meta-analysis to evaluate the exact association between co-rumination and depressive symptoms in children, adolescents, and young adults. A total of 66 studies (27,794 participants) were included in the meta-analysis. In this study, the main effect test revealed a significant positive correlation between co-rumination and depressive symptoms (n = 70; r = 0.128; 95% CI = 0.106 to 0.150). Moreover, age was found to be a significant moderator. Specifically, the association between co-rumination and depressive symptoms was weaker in adolescents compared to undergraduates and adults. In addition, measure of co-rumination was identified as an important moderator, showing marginal significance. The association was stronger when using the original Co-Rumination Questionnaire compared to other versions and code methods. Finally, the relationship between co-rumination and depressive symptoms was not moderated by gender, measure of depressive symptoms, publication year, study quality, or simple size. The current study reveals the positive association between co-rumination and depressive symptoms while highlighting both the positive and negative trade-offs of co-rumination.

Effectiveness of a blended school-based mindfulness program for the prevention of co-rumination and internalizing problems in Dutch secondary school girls: a cluster randomized controlled trial

BACKGROUND

A growing body of literature indicates that adolescent girls who talk with close friends about interpersonal problems or worries in an excessive, speculative way, and with an intense focus on distress (i.e., co-rumination) are at heightened risk for developing internalizing symptoms and disorders as well as reduced friendship quality. However, to date, there are no prevention programs available that target high levels of co-rumination between adolescent girls. As such, we developed the blended school-based mindfulness prevention program Happy Friends, Positive Minds (HFPM) that targets co-rumination at the dyadic level, i.e., between two close female friends. The aim of this trial is to evaluate the effectiveness of HFPM to reduce co-rumination and internalizing problems and to enhance wellbeing and social-emotional behavior in Dutch adolescent girls.

METHODS

A cluster Randomized Controlled Trial (cRCT) will be conducted to evaluate HFPM effectiveness. We will recruit 160 female friendship dyads (n = 320 girls) aged 13 to 15 years who will be characterized by high levels of self-reported co-rumination. The cRCT has two arms: (1) an intervention condition in which 160 girls (80 friendship dyads) will receive the 14-week HFPM program in two consecutive cohorts (cohort 1 in academic year 2023/2024 and cohort 2 in academic year 2024/2025, and (2) a control condition in which 160 girls (80 dyads) will receive care-as-usual (CAU) in two consecutive cohorts (cohort 1 in academic year 2023/2024 and cohort 2 in academic year 2024/2025). Data will be collected at baseline (T0), during the program (T1;T2; T3), immediately after the program (T4), and at 1-year follow-up (T5). Participant-level self-reported risk for (early onset) depression and anxiety, self-reported and observed co-rumination, self- and friend-reported friendship quality, self-reported positive and negative affect, self-reported interpersonal responses to positive affect, and self-reported anhedonia symptoms will be the outcome variables.

DISCUSSION

This study will provide insights into the short-term and long-term effects of the HFPM program on girls' internalizing problems, wellbeing, and social-emotional behavior.

Interpersonal Factors, Peer Relationship Stressors, and Gender Differences in Adolescent Depression

PURPOSE OF REVIEW

Compared to boys, girls value close relationships more. Thus, heightened affiliative proclivities may serve as a particularly salient psychosocial risk factor for depression in adolescent girls. The purpose of this review is to examine whether the preponderance of depression in girls is because of gender differences in interpersonal vulnerabilities and peer relationship stressors and/or in the associations between these factors and depression.

RECENT FINDINGS

Girls (vs. boys) exhibit higher levels of co-rumination and affective empathy, but not excessive reassurance-seeking. The prevalence of different forms of peer relationship stressors (e.g., peer victimization) varies by gender depending on the specific type. Evidence is mixed regarding gender differences in the association between peer victimization and depression. Gender differences in the association between peer victimization and depression not only depend on peer victimization subtype but also on the country. Most studies were conducted in non-clinical samples, highlighting the need for future research to assess major depressive disorder (not just depressive symptoms). Future research should also assess interpersonal factors (e.g., co-rumination) and peer relationship stressors together.

Decomposing variance in co-rumination using dyadic daily diary data

It is unknown how co-rumination, or perseverating on problems or feelings with another person, unfolds in the daily lives of romantic couples. Using a variance decomposition procedure on data from a 14-day dyadic diary, we assessed how much variance in co-rumination was attributable to temporally stable and varying factors, as well as whether co-rumination is better measured as a couple-level or individual-level process. Within-person, within-couple fluctuations in co-rumination contributed most (~33%) to the total variance and summary scores based on these fluctuations were reliable. Stable between-couple differences accounted for ~14% of the total variance and could also be reliably assessed. However, within-couple agreement in co-rumination was low, such that the reliability at the level of within-couple change was inadequate. Research is needed to understand these divergent perceptions of co-rumination and potential downstream consequences. We conclude by considering how these results inform theory and can be applied to similar dyadic constructs.

Co-rumination and conversational self-focus: Adjustment implications of problem talk in adolescents' friendships

Friendships are central relationships during adolescence. Given the increased experience of stress during adolescence, friends are especially critical sources of support at this time. Although experiencing social support is related to well-being, adolescents' experiences sharing problems with friends is not always positive. In this chapter, we consider two forms of problematic talk, co-rumination and conversational self-focus. Co-rumination refers to conversations about problems that is excessive, repetitive, speculative, and focused on negative affect. Conversational self-focus refers to adolescents re-directing conversations about friends' problems to oneself. Both co-rumination and conversational self-focus are associated with depressive symptoms. However, whereas co-rumination draws friends together and is associated with positive friendship quality, adolescents who engage in conversational self-focus are increasingly rejected by friends. Directions for future research and applied implications of studying social support processes between friends are discussed.

Best Friend's Popularity: Associations with Psychological Well-Being and School Adjustment in China During Early Adolescence

Popularity has been empirically linked to psychological and several indices of school adjustment outcomes during childhood and early adolescence. Yet, best friend popularity in relation to the adjustment outcomes remains unclear, especially in more interdependent-oriented cultures. To address this gap, this study applied the Actor-Partner Interdependence Model (APIM) to simultaneously considering whether, and how, the popularity of youth (actor effects) and their best friends (partner effects) contribute uniquely to psychological well-being and school adjustment outcomes, after controlling for social preference. Age and gender differences were also examined. Participants were 162 same-gender best friend dyads (81 boys, M_age = 11.24 years, SD = 1.18) from Shanghai, P.R. China. Among the results, both youth's own and their best friends' popularity were positively related to self-esteem and school attitudes, and negatively related to depressive symptoms. In addition, results from multi-group analyses revealed both actor and partner effects did not vary across gender. Finally, exploratory analyses showed that only actor effects varied across age for the associations between popularity and self-esteem and school attitudes. These findings highlight the important role of the best friend's popularity in promoting Chinese youth's experiences of psychological and school adjustment.

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.

Psychological factors in adherence to COVID-19 public health restrictions in Italy: A path model testing depressed mood, anxiety, and co-rumination via cellphone

During the COVID-19 pandemic, the success of major non-pharmaceutical interventions, such as quarantine orders, has depended upon robust rates of citizens' adherence to protocols. Thus, it is critical to public health for research to illuminate factors that affect compliance with contagion-mitigating practices. Previous research has examined sociodemographic factors and aspects of psychological distress as correlates of adherence to public health guidelines. The current study expanded this research to investigate the psychosocial process of co-rumination, which has been identified in previous research as a maladaptive type of social interaction that is associated with elevated levels of anxiety and depression. Data were collected from 932 Italian adults during the initial stages of the highly stressful COVID-19 pandemic and lockdown. A path model was tested to examine multivariate relationships among sociodemographic characteristics, symptoms of psychological distress (i.e., depression and anxiety), co-rumination via cellphone, and self-reported adherence to COVID-19-related public health restrictions. Results revealed that higher rates of co-rumination via cellphone were associated with lower levels of adherence to public health restrictions. Symptoms of depression and anxiety were differentially related to co-rumination processes and adherence to public health restrictions. Higher levels of depression symptoms were directly associated with poorer adherence to public health restrictions, and this path was mediated through higher levels of co-rumination via cellphone. On the contrary, higher levels of state anxiety were directly associated with greater adherence to public health guidelines. This path was also mediated through co-rumination via cellphone. Higher levels of anxiety were correlated with lower levels of co-rumination, which in turn were correlated with lower levels of adherence. These results suggest fruitful directions for future research examining co-rumination as a maladaptive coping behavior that may be addressed within public health interventions.

Maternal Depression and Mother-Child Oxytocin Synchrony in Youth with Anxiety Disorders

The neuropeptide oxytocin (OT) plays a central role in the regulation of affiliative bonds and anxiety. However, the degree to which its levels are synchronized between interaction partners has not yet been assessed. Physiological synchrony assessed using other peripheral measures (e.g., heart rate, etc.) has been tied to positive outcomes for the individual and the dyad. The present study examined OT synchrony in the context of child anxiety and maternal depression by examining mother-child dyads. Mothers and their children with anxiety disorders participated in a behavioral interaction task. Changes in OT levels and mother-child OT synchrony before and after the interaction, as well as their moderation by maternal depression, were assessed. Ninety-eight youth with anxiety disorders (ages 10 to 17) and their mothers underwent psychiatric evaluation, and mothers rated their own depressive symptoms and their children's behavior problems. Salivary OT was assayed from mother and child before and after the task. Behavioral coding showed that interactions were characterized by high behavioral synchrony between mothers and their children, and both individuals displayed higher levels of positive vs. negative affect during the interactions. Mothers and their children also showed decreases in OT levels after the interaction. As hypothesized, OT synchrony increased following the task, but only dyads in which mothers showed high levels of depressive symptoms showed this increase. As hypothesized, lower levels of OT-synchrony were associated with higher levels of child internalizing symptoms. The findings suggest that positive interactions may be beneficial for youth with anxiety disorders with mothers with depression.
