Lonely in Different Relationships: Bidirectional Effects between Parent- and Peer-Related Loneliness in Adolescence.

Although it is assumed that loneliness in one relationship might put one at risk of experiencing loneliness in another relationship, this association has rarely been examined as such. In this longitudinal study, we examined the associations between peer- and parent-related loneliness in a sample of 3391 adolescents across three waves (Mage Wave 1 = 14.53; 59.3% female). Using random intercept cross-lagged panel models, parent- and peer-related loneliness were found to be stable over time and were concurrently related to each other. Moreover, the state of peer-related loneliness predicted the state of parent-related loneliness one year later. Thereby, the current study provides limited evidence of a carry-over effect between relation-specific types of loneliness.

Do Gender and Age Moderate the Relationship between Friendship Quality and Non-Suicidal Self-Injury in Community Children and Adolescents?

In the present study, we investigated the relationship between friendship quality (dimensions) and non-suicidal self-injury (NSSI) as well as the moderating role of gender and age in this relationship. The sample consisted of 463 children and adolescents (50.10% female, age range: 9-17 years). Friendship quality and NSSI were measured using the Friendship Qualities Scale (FQS; Bukowski, Hoza, & Boivin, 1994) and the Self Harm Inventory (SHI; Sansone, Wiederman, & Sansone, 1998), respectively. Overall, total friendship quality and NSSI were significantly and negatively related. Additionally, the relationship between total friendship quality and NSSI was moderated by gender and age. Specifically, girls with low friendship quality reported more NSSI; whereas for boys an opposite effect was found. As for age, friendship quality and NSSI were positively related in older participants. In younger participants, a relationship between friendship quality and NSSI seemed rather absent. This study highlights the important association between friendship quality and NSSI, as well as gender- and age-related differences in this association, which should be taken into account in the prevention and treatment of NSSI.

Problem Talk in Adolescence: Temperament and Attachment as Predictors of Co-Rumination Trajectories in Boys and Girls.

Co-rumination has consistently been shown to be maladaptive in the context of emotional well-being. However, not much is known about factors that predict one's tendency to co-ruminate. The current study investigated temperament, attachment, and gender as predictors of co-rumination trajectories in a sample of 1549 early and middle adolescents from fifth to ninth grade (53.4% girls; Mage = 12.93). Analyses were performed on four waves of data with one-year intervals using multi-level modeling. First, girls were found to be more likely to co-ruminate. Second, high positive affectivity in boys and girls and high effortful control in boys was related to higher co-rumination. Third, high attachment anxiety and high general trust in the availability and support of a mother were predictive of higher co-rumination levels. High attachment avoidance was negatively related to co-rumination in boys. High positive affectivity in boys and girls and high trust in boys predicted decreases in reported co-rumination levels over time. Results highlight differences between boys and girls in factors that predict the tendency to co-ruminate. The current study adds to the literature by helping to identify factors associated with the development of co-rumination, which is a well-established risk factor of internalizing symptoms. Monitoring youth affected with these vulnerabilities may be recommended for prevention efforts.

Attachment and the Development of Depressive Symptoms in Adolescence: The Role of Regulating Positive and Negative Affect.

Although widely accepted, attachment theory's hypothesis that insecure attachment is associated with the development of depressive symptoms through emotion regulation strategies has never been longitudinally tested in adolescence. Additionally, previous research only focused on strategies for regulating negative affect, whereas strategies for regulating positive affect may also serve as a mechanism linking insecure attachment to depressive symptoms. This study aimed to fill these research gaps by testing whether the association between attachment and change in depressive symptoms over time is explained by strategies for regulating negative and positive affect in adolescence. Adolescents (N = 1706; 53% girls; Mage = 12.78 years, SDage = 1.54 at Time 1) were tested three times, with a 1-year interval between measurement times. They reported on their attachment anxiety and avoidance at Time 1, depressive symptoms at Times 1 and 3, and regulation of negative affect (brooding and dampening) and positive affect (focusing and reflection) at Time 2. The results from multiple mediation analyses showed that more anxiously attached adolescents developed more depressive symptoms via increased brooding and dampening. More avoidantly attached adolescents developed more depressive symptoms via decreased focusing. These findings provide longitudinal support for attachment theory's emotion regulation hypothesis, and show that the regulation of both negative and positive affect is important.

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.

Loneliness, Social Anxiety Symptoms, and Depressive Symptoms in Adolescence: Longitudinal Distinctiveness and Correlated Change.

Loneliness, social anxiety symptoms, and depressive symptoms are internalizing problems that are highly intertwined and often co-occur during adolescence. This overlap and co-occurrence raises the question whether three different labels are used for the same underlying phenomenon. The present study adopts a comprehensive approach to this issue by investigating the development of the three phenomena simultaneously. Specifically, this study aimed to investigate (1) the developmental trend for all three internalizing problems separately, (2) whether they are best described by a single developmental trend, (3) how they co-develop across adolescence, and (4) gender differences in this co-development. The analyses were run in three three-wave longitudinal samples of adolescents with one-year intervals in order to verify the robustness of the findings. Sample 1 (roughly ages 15, 16, and 17) comprised 549 adolescents (63% girls), and Samples 2 and 3 (roughly ages 13, 14, and 15) comprised 811 adolescents (46% girls) and 1101 adolescents (52% girls), respectively. Latent growth curve modeling for the three phenomena separately showed either small increases or stable patterns. A comparison of a Multiple Indicator Latent Growth Model (MILGM) with a Parallel Process Latent Growth Curve Modeling (PPLGCM) showed that the three internalizing problems followed unique, but related, developmental trends across adolescence. The intercepts of the three phenomena were positively correlated with one another in all samples and increases in loneliness were associated consistently with increases in social anxiety symptoms. Only in Sample 3 evidence was found for a similar association between loneliness and depressive symptoms and between social anxiety symptoms and depressive symptoms. Except for differences in initial levels, gender differences in the development of the three problems were limited. Overall, the results of the present study clearly indicate that the three internalizing problems are longitudinally distinct from one another, but co-develop across adolescence.

Repetitive Negative Thinking outperforms loneliness and lack of social connectedness as a predictor of prospective depressive symptoms in adolescents.

BACKGROUND: Repetitive Negative Thinking (RNT) is a well-established predictor in adolescents of emotional problems, such as depression. Surprisingly little research, however, has looked at the relative importance of RNT vs. more interpersonally relevant variables in the context of depression, such as loneliness and lack of social connectedness. OBJECTIVE: The present study, therefore, set out to examine whether RNT is a significant predictor when taking into account the contribution of loneliness and social connectedness. METHODS: A sample of 135 typically developing adolescents (N = 135; 79.3% girls; M age = 17.5; range 16-21) completed measures of depressive symptoms, RNT, loneliness and social connectedness at two time points with a 3-month interval. RESULTS: Results showed that above and beyond baseline depressive symptoms, RNT was the only other significant predictor of prospective depressive symptoms. CONCLUSIONS: According to these results, RNT seems a relatively more important factor to consider in the context of adolescent depression than factors in the interpersonal or social context. Consequently, targeting RNT might be expected to yield more significant gains in reducing or preventing depressive symptoms in adolescents compared to focusing on feelings of loneliness or social connectedness - a hypothesis that remains to be tested.

Temporal associations between social anxiety and depressive symptoms and the role of interpersonal stress in adolescents.

BACKGROUND: Adolescence is characterized by an increased vulnerability for internalizing psychopathologies such as depression and anxiety. A positive association between anxiety and depression has consistently been found in research. However, the specific direction of this association is less clear. In this study, we investigated the temporal associations between (social) anxiety and depressive symptoms. Furthermore, the role of dependent interpersonal stress as a potential mediating factor in these temporal associations was examined. METHODS: Data were part of a larger longitudinal study on the emotional development of adolescents, which was initiated in February 2013. The total sample consisted of 2011 adolescents between the ages of 11 and 19. Data were analyzed using cross-lagged models. RESULTS: Bidirectional positive associations were found between social anxiety symptoms and depressive symptoms. However, dependent interpersonal stress was not a mediator in the link between social anxiety and depression. Our results indicate that dependent interpersonal stress seems to be particularly related to depressive symptoms and not to social anxiety symptoms. CONCLUSIONS: Findings suggest that bidirectional associations between social anxiety and depressive symptoms exist. This implies that clinicians should be specifically vigilant for the development of depressive symptoms in socially anxious adolescents and the development of social anxiety symptoms in depressed adolescents. Our findings further highlight the importance of targeting dependent interpersonal stress in the context of depression.

Internalizing Problems in Adolescence: Linking Loneliness, Social Anxiety Symptoms, and Depressive Symptoms Over Time.

Adolescents are particularly vulnerable to experiencing loneliness, social anxiety symptoms, and depressive symptoms. These internalizing problems often co-occur but, until now, it remains unclear how they are associated over time. Insight in these temporal sequences is important to enhance our understanding of how internalizing problems arise and may reinforce each other over time. To examine these temporal sequences, three samples of adolescents were used: Sample 1 consisted of 1,116 adolescents (48.97% girls, Mage = 13.59), Sample 2 of 1,423 adolescents (52.42% girls, Mage = 13.79), and Sample 3 of 549 adolescents (62.66% girls, Mage = 14.82). Adolescents filled out well-established self-report measures of loneliness, social anxiety symptoms, and depressive symptoms during regular school hours at three measurement occasions with a 1-year interval. Meta-analytic techniques were used to estimate the average true effects across three-variable autoregressive cross-lagged models in the three samples. In addition, indirect effects and gender differences in the temporal associations were explored in all three samples. The results suggest that social anxiety symptoms play a crucial role as potential antecedent of emerging feelings of loneliness and depression in adolescence. In addition, in line with theoretical expectations, our results suggest the presence of a vicious cycle between adolescents' feelings of loneliness and social anxiety symptoms. The indirect effects were inconsistent across samples and no gender differences were found. These findings shed more light on the unique temporal relationships among different internalizing problems. Clinical interventions should target social anxiety symptoms to prevent feelings of loneliness and vice versa.

When Do Good Things Lift You Up? Dampening, Enhancing, and Uplifts in Relation To Depressive and Anhedonic Symptoms in Early Adolescence.

Longitudinal studies examining the role of response styles to positive affect (i.e., dampening and enhancing) for depressive symptoms have yielded inconsistent results. We examined concurrent and prospective relations of dampening and enhancing with depressive and anhedonic symptoms, and whether these relations depend on the frequency of uplifts. Early adolescents (N = 674, 51.6% girls, Mage = 12.7 years, range 11.3-14.9) completed questionnaires three times (one-year intervals). Dampening interacted with daily uplifts predicting concurrent depressive symptoms. Dampening was unrelated to depressive and anhedonic symptoms one year later. High dampening and low enhancing predicted relative increases in anhedonia over two years. Relationships did not differ for girls and boys. Therapeutic interventions designed to promote adaptive responding to positive affect may, thus, reduce anhedonia in adolescence.

Party Pooper or Life of the Party: Dampening and Enhancing of Positive Affect in a Peer Context.

Dampening and enhancing responses to positive affect have been linked to depressive symptoms. The main aim of the present study was to examine such responses in an interpersonal peer context and to examine their relation with depressive symptoms. A community sample of 665 seventh-graders (52.0% girls, Mage = 12.7 years) took part in the study. Using a newly developed questionnaire, the Co-Dampening and Co-Enhancing Questionnaire (CoDEQ), a two-factor model distinguishing co-dampening and co-enhancing was validated. Relations with general depressive symptoms, anhedonic symptoms, and friendship quality were investigated. The direction of relations was examined over a 1-year interval using cross-lagged analyses. Cross-sectional results revealed that higher levels of co-dampening and lower levels of co-enhancing were associated with more depressive and anhedonic symptoms, while controlling for co-rumination levels. For anhedonic symptoms, this pattern also held over and above intrapersonal dampening and enhancing. Friendship quality was related to higher concurrent levels of co-enhancing and lower levels of co-dampening. The longitudinal results pointed towards a scar model, in that both depressive and anhedonic symptoms predicted relative increases in co-dampening over time; however, this did not hold in a model in which dampening and enhancing were included as control variables.

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.

Adolescents' Loneliness and Depression Associated with Friendship Experiences and Well-Being: A Person-Centered Approach.

Loneliness and depressive symptoms are distinct, but partly overlapping constructs. The current study examined whether clusters of loneliness and depressive symptoms could be identified through latent profile analysis in two samples of 417 and 1140 adolescents (48.40 and 48.68 % male, respectively), on average 12.47 and 12.81 years old, respectively. Four clusters were identified, (1) low on loneliness and depressive symptoms, (2) low on loneliness and high on depressive symptoms, (3) high on loneliness and low on depressive symptoms, and (4) high on loneliness and depressive symptoms. We found that these four clusters were differentially related to friendship quantity and quality as well as to happiness and self-esteem. The current study stresses the importance of assessing both loneliness and depressive symptoms, as their mutual relation within individuals is differentially related to various aspects of adjustment.

Moderating effects of brooding and co-rumination on the relationship between stress and depressive symptoms in early adolescence: a multi-wave study.

The current study investigated brooding and co-rumination as moderators of the relationship between interpersonal and noninterpersonal stress and depressive symptom trajectories. The sample consisted of 368 early adolescents ages 9 to 15 (M = 11.72, 63 % female) who completed self-report measures of brooding, co-rumination, stress, and depressive symptoms at baseline with follow-up assessments of stress and depressive symptoms at 3, 8, and 12 months post-baseline. Data were analyzed using multi-level modeling. Results showed that the association between interpersonal stress and depressive symptoms was stronger for adolescents high on brooding, compared to adolescents low on brooding. Sex moderated a co-rumination × stress interaction, with girls high on co-rumination and boys low on co-rumination reporting the highest levels of depressive symptoms when faced with interpersonal stress across the 1-year study period. These findings shed light on pathways to depressive symptoms in early adolescence and suggest that adolescent boys and girls may differ in these pathways.
