Co-rumination between friends: Considering the roles of outcome expectations, relationship provisions, and perceptions of problems.

Despite its implications for adjustment, little is known about factors that support co-rumination in friendships. The current multi-method, longitudinal study addressed this question with 554 adolescents (Mage = 14.50; 52% girls; 62% White; 31% Black; 7% Asian American) from the Midwestern United States in 2007-2010. Adolescents were observed talking about problems with a friend and reported on their outcome expectations for problem disclosures, relationship provisions during problem talk, and problem perceptions after problem talk. Participants reported on outcome expectations again 9 months later. Results indicate that the positive relationship provisions associated with co-rumination may outweigh negative problem perceptions in predicting adolescents' outcome expectations for problem disclosures over time. Implications for the potentially reinforcing nature of co-rumination are discussed.

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.

Adolescent emotion regulation trajectories: The influence of parent and friend emotion socialization.

With mounting evidence demonstrating the link between child emotion regulation (ER) and emotion socialization, we conducted a longitudinal study to understand (a) emotion-specific trajectories of adolescent ER and (b) how specific parent and friend emotion socialization strategies impact ER over 4 years. Participants were 209 adolescents (52.5% girls; Mage  = 12.66 years; 75.7% White) and their parents. Latent growth curve models identified unique trajectories for anger and sadness/worry regulation. Anger regulation increased across time, whereas sadness/worry regulation remained highly stable longitudinally, lacking variance for growth modeling. Friend emotion socialization emerged as a more salient predictor of anger regulation than parent emotion socialization. Friend reward, override, and punish responses predicted initial levels. Friend punish and parent magnify responses predicted the slope.

DIAPH1 facilitates paclitaxel-mediated cytotoxicity of ovarian cancer cells.

The chemotherapeutic agent paclitaxel (PTX) selectively binds to and stabilizes microtubule (MTs). Also, the activated formin Diaphanous Related Formin 1 (DIAPH1) binds to MTs and increases its stability. In a recent study, we found that high DIAPH1 levels correlated with increased survival of ovarian cancer (Ovca) patients. A possible explanation for this finding is that Ovca cells with high DIAPH1 levels are more sensitive to PTX. To examine this assumption, in this study the effect of DIAPH1 depletion on PTX-mediated cytotoxicity of OVCAR8 and OAW42 cells was analyzed. Our data showed that down-regulation of DIAPH1 expression decreased PTX sensitivity in both cell lines by reducing apoptosis or necrosis. Analysis of MT stability by Western blotting revealed a decreased concentration of stable, detyrosinated MTs in PTX-treated DIAPH1 knock-down compared to control cells. Also, in fixed metaphase cells the level of stable, detyrosinated spindle MTs decreased in cells with reduced DIAPH1 expression. In vitro analysis with recombinant DIAPH1 protein showed that PTX and DIAPH1 exhibited additive effects on MT-polymerization, showing that also in a cell-free system DIAPH1 increased the effect of PTX on MT-stability. Together, our data strongly indicate that DIAPH1 increases the response of Ovca cells to PTX by enhancing PTX-mediated MT-stability.

Boys' and Girls' Interactions With Same-Gender Friends and Other-Gender Friends: A Focus on Problem Disclosures.

The current study examines adolescents' subjective experiences interacting with same-gender and other-gender friends, with a focus on interactions involving disclosure about personal problems. Participants were 510 youth (65% White or European American, 26% Black or African American) in seventh grade (n = 244; M = 13.01 years; 51% girls) and tenth grade (n = 266; M = 16.03 years; 52% girls). Adolescents completed an event-contingent sampling assessment to record interactions with same-gender and other-gender friends. Results indicated that middle adolescents were more likely to interact with other-gender friends than early adolescents. Girls were more likely to report problem disclosure interactions than boys; however, boys reported more positive subjective experiences in problem disclosure interactions with other-gender friends than did girls.

The significance of early temperamental reactivity for children's social competence with peers: A meta-analytic review and comparison with the role of early attachment.

Early temperamental reactivity and attachment security are key predictors of children's social competence with peers. Leveraging meta-analytic evaluation of the significance of early attachment for social competence already available (Groh et al., 2014), this quantitative review examined the significance of early temperamental reactivity for social competence with peers and compared the strength of this association with that for attachment. Based on 140 independent samples (u = 382; N = 49,891), the meta-analytic association between early difficult temperament and (lower) social competence was significant (r = 0.13, z = 0.13; 95% CI [0.11, 0.16]), but decreased as time between assessments increased. Findings were similar for negative and positive emotionality. Greater negative emotionality was associated with lower social competence (r = 0.14, z = 0.14; 95% CI [0.11, 0.17], k = 93, u = 172), and greater positive emotionality was associated with better social competence (r = 0.18, z = 0.18; 95% CI [0.12, 0.24], k = 43, u = 54). Meta-analytic associations were reduced when overlapping informants and overlapping items in temperament and social competence assessments were excluded (difficult temperament: r = 0.10, z = 0.10; 95% CI [0.06, 0.13]; negative emotionality: r = 0.10, z = 0.10; 95% CI [0.05, 0.15]; positive emotionality: r = 0.10, z = 0.10; 95% CI [0.06, 0.14]). Meta-analytic associations between these broadband temperament dimensions and social competence were smaller than the meta-analytic association between attachment security and social competence. Discussion focuses on the developmental significance of early temperament for social competence and ways to reconcile literatures on early temperament and attachment in future research on the developmental antecedents of children's social competence.

Relations of friendship experiences with depressive symptoms and loneliness in childhood and adolescence: A meta-analytic review.

Well-established psychological theories indicate that interpersonal relationships and emotional well-being are linked in fundamental ways (Coyne, 1976; Sullivan, 1953). Indeed, difficulties in close relationships can contribute to emotional adjustment problems, and emotional problems can adversely affect close relationships. Moreover, different close relationships are especially significant in terms of development and adjustment at different stages of the life span. The current review focuses on childhood and adolescence, developmental stages at which friendships are particularly important. This article presents the results of 16 meta-analyses including 589 unique effects from 233 studies that examine concurrent and longitudinal associations between youths' friendship experiences (number of friends, positive friendship quality, negative friendship quality) and their emotional adjustment (depressive symptoms and loneliness). Studies examining these associations are mixed in regard to whether significant effects emerge. The current research synthesis provides more stable estimates of the effects. In fact, relatively small but significant concurrent and longitudinal associations emerged between the 3 indices of friendship with depressive symptoms and loneliness. The results also suggest that friendship experiences may be more closely linked with loneliness than depressive symptoms and that negative friendship quality may be related to friendship experiences more strongly than number of friends or positive friendship quality. Interestingly, some of the relations were found to be stronger for younger youth. Implications for prevention and intervention efforts are discussed.

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

Research suggests co-rumination during adolescence has developmental tradeoffs that result in elevated self-disclosure and intimacy between friends but also can be associated with increases in depression (Rose et al. 2007; Rose 2002). The current study further examined this paradox by assessing the role of emotional competencies in co-rumination as they predict depressive symptoms over a 2-year period. We tested whether co-rumination moderated the relation between emotional awareness and emotion regulation and depressive symptoms in reciprocated best friend dyads. At Time 1, 202 adolescents (101 same-sex best friend dyads; Mage = 12.68, 52.5% girls, 76.6% White, middle-class) reported on their emotional competencies (i.e., emotional awareness and perceptions of their friend's anger and sadness regulation), and depressive symptoms as well as engaged in a discussion task where co-rumination was observed. Multilevel modeling (Actor-Partner Interdependence Modeling) was used to account for similarity within friend dyads. The results indicated that when girls engaged in high levels of co-rumination, poor emotional awareness was related to greater depressive symptoms in their friend. Regarding the analyses of emotion regulation, at high levels of co-rumination, Friend A's perceptions of stronger anger regulation by Friend B predicted fewer depressive symptoms in Friend A. Stronger sadness regulation in Friend B at high levels of co-rumination predicted fewer depressive symptoms in Friend B. Our findings highlight the potentially adaptive nature of emotional competencies that may ameliorate the negative sequelae of co-rumination as adolescents are afforded the opportunity to discuss problems, better understand their emotions, skills that are then associated with fewer depressive symptoms over time.

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms.

Through stress generation, individuals' own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.

Adolescent controversial status brokers: A double-edged sword.

Using a 3-wave longitudinal, multidimensional approach, this study investigated the influence of social network position and social status on the psychosocial outcomes of 440 youth (45.1% girls; Mage = 16.1 years; 90.9% Caucasian) over 26 months, focusing on the controversial status classification (i.e., youth who are highly liked and disliked by their peers). Brokerage (i.e., the degree to which a person has relationships with peers who do not have a direct relationship with each other) was examined in conjunction with sociometric status to explain potential heterogeneity of outcomes for controversial status youth. Adolescents completed peer nominations and self-reports of adjustment. Results demonstrated that brokerage was related to poorer psychosocial outcomes for controversial compared to average status youth. Brokerage appears to add predictive value to youths' adjustment beyond traditional sociometric classifications, especially for controversial status youth. (PsycINFO Database Record

Socialization in the Context of Risk and Psychopathology: Maternal Emotion Socialization in Children of Incarcerated Mothers.

Children of incarcerated mothers are at increased risk for psychological, social, and emotional maladaptation. This research investigates whether perceived maternal socialization of sadness and anger may moderate these outcomes in a sample of 154 children (53.9% boys, 61.7% Black, M age = 9.38, range: 6 - 12), their 118 mothers (64.1% Black), and 118 caregivers (74.8% female, 61.9% grandparents, 63.2% Black). Using mother, caregiver, and child report, seven maternal socialization strategies were assessed in their interaction with incarceration-specific risk experiences predicting children's adjustment. For sadness socialization, the results indicated that among children reporting maternal emotion-focused responses, incarceration-specific risk predicted increases in psychological problems, depressive symptoms, increased emotional lability, and poorer emotion regulation. For children who perceived a problem-focused response, incarceration-specific risk did not predict outcomes. There were no significant interactions with incarceration-specific risk and perceived maternal anger socialization strategies. These results indicate a critical need to examine how socialization processes may operate differently for children raised in atypical socializing contexts.
