Testing transactional processes between parental support and adolescent depressive symptoms: From a daily to a biennial timescale.

Transactional processes between parental support and adolescents' depressive symptoms might differ in the short term versus long term. Therefore, this multi-sample study tested bidirectional within-family associations between perceived parental support and depressive symptoms in adolescents with datasets with varying measurement intervals: Daily (N = 244, Mage = 13.8 years, 38% male), bi-weekly (N = 256, Mage = 14.4 years, 29% male), three-monthly (N = 245, Mage = 13.9 years, 38% male), annual (N = 1,664, Mage = 11.1 years, 51% male), and biennial (N = 502, Mage = 13.8 years, 48% male). Preregistered random-intercept cross-lagged panel models (RI-CLPMs) showed negative between- and within-family correlations. Moreover, although the preregistered models showed no within-family lagged effect from perceived parental support to adolescent depressive symptoms at any timescale, an exploratory model demonstrated a negative lagged effect at a biennial timescale with the annual dataset. Concerning the reverse within-family lagged effect, increases in adolescent depressive symptoms predicted decreases in perceived parental support 2 weeks and 3 months later (relationship erosion effect). Most cross-lagged effects were not moderated by adolescent sex or neuroticism trait level. Thus, the findings mostly support adolescent-driven effects at understudied timescales and illustrate that within-family lagged effects do not generalize across timescales.

Perceived Parental Support and Psychological Control, DNA Methylation, and Loneliness: Longitudinal Associations Across Early Adolescence.

A broad range of factors have been associated with the development of adolescent loneliness. In the family context, a lack of parental support and high levels of parental psychological control have systematically been linked to loneliness. On the biological level, DNA methylation (which is an epigenetic process that suppresses gene expression) is believed to play a role in the development of loneliness. Specifically, high levels of DNA methylation in genes that play an important role in the functioning of the human stress response system are believed to elevate the risk of loneliness. Moreover, DNA methylation levels in these stress-related genes can be influenced by stressful environmental factors, suggesting a potential mediating role of DNA methylation in the association between parenting behaviors and loneliness. The current 3-year longitudinal study is the first study to examine the potential bidirectional longitudinal associations between loneliness, DNA methylation in stress-related genes, and both perceived parental support and psychological control. Furthermore, we explored the potential mediating role of DNA methylation in stress-related genes in the associations between perceived parenting and loneliness. The sample comprised 622 early adolescents (55% girls, Mage T1 = 10.77 years, SDage T1 = 0.48) who were followed from Grade 5 to 7. Parental support, psychological control, and loneliness were assessed annually by adolescent self-report questionnaires and DNA methylation was determined from saliva samples. Cross-Lagged Panel Models (CLPM) revealed that higher levels of loneliness predicted lower perceived parental support and higher perceived psychological control over time, as well as higher DNA methylation in some stress-related genes, that is, the glucocorticoid receptor gene (NR3C1) and the brain-derived neurotrophic factor (BDNF). In addition, higher NR3C1 methylation was predictive of lower perceived parental support and higher psychological control over time. No evidence was found for a mediating role of DNA methylation. Overall, our longitudinal findings challenge the current focus on DNA methylation and parenting behaviors as risk factors for adolescent loneliness. Instead, they suggest that the less considered direction of effects, which implies that loneliness predicts DNA methylation and aspects of parenting such as support and psychological control, should receive greater attention in future research.

Depression Socialization in Early Adolescent Friendships: The Role of Baseline Depressive Symptoms and Autonomous Functioning.

There is mixed evidence for depression socialization, a process by which friends affect each other's level of depressive symptoms. The current study examined whether adolescents' baseline depressive symptoms and three dimensions of autonomous functioning (autonomy, peer resistance, and friend adaptation) make adolescents more or less sensitive to depression socialization, and how these dimensions of autonomous functioning were connected. In this preregistered, two-wave longitudinal study, participants completed questionnaires on depressive symptoms, autonomy, and peer resistance and participated in a task to assess friend adaptation. Participants were 416 Dutch adolescents (Mage = 11.60, 52.8% girls) across 230 close friend dyads. In contrast to expectations, results showed no significant depression socialization nor significant moderation. Furthermore, autonomy and peer resistance were related but distinct constructs, and not related to friend adaptation. These findings suggest that there is no depression socialization in early adolescence, regardless of level of autonomous functioning.

Longitudinal Associations Between Depressive Symptoms and Quality of Romantic Relationships in Late Adolescence.

While youth with higher levels of depressive symptoms appear to have lower quality romantic relationships, little is known about longitudinal associations for both men and women. Therefore, this study used longitudinal dyadic design to examine both concurrent and longitudinal associations between depressive symptoms and positive as well as negative aspects of romantic relationship quality across two waves one- or two-years apart. The sample consisted of 149 Dutch stable heterosexual couples (149 females and 142 males participated at T1) in a stable romantic relationship in late adolescence with a mean age of 20.43 years old at the first wave. Actor-Partner Interdependence models were used to examine potential bidirectional associations over time between depressive symptoms and romantic relationship quality, above and beyond potential concurrent associations and stability of the constructs over time, from the perspective of both romantic partners. Results consistently indicated that men and women who reported higher levels of depressive symptoms perceived less positive aspects (intimacy and support) and more negative aspects (conflict) in their romantic relationship over time. In addition, unexpectedly, when men and women perceived more positive relationship aspects, their partners reported higher levels of depressive symptoms over time. These findings stress that depressive symptoms can interfere with the formation of high-quality romantic relationships.

Friend Support and Internalizing Symptoms in Early Adolescence During COVID-19.

The COVID-19 pandemic has impacted adolescents' psychosocial adjustment and social relationships across the world. This prospective longitudinal study examined whether internalizing problems during the pandemic could be predicted by precrisis friend support, and whether this effect was moderated by the time adolescents spent with their friends and COVID-19-related stress. 245 Dutch adolescents (Mage  = 11.60) participated before and during COVID-19. Higher pre-COVID-19 friend support predicted less (self-reported and parent-reported) internalizing problems during COVID-19, and this effect was not moderated by the time adolescents spent with friends or COVID-19-related stress. Friends may thus protect against developing internalizing symptoms in times of crisis. We also found the reverse effect: Internalizing problems before COVID-19 were predictive of friend support during COVID-19.

Identity development across the transition from secondary to tertiary education: A 9-wave longitudinal study.

INTRODUCTION: The transition from secondary to tertiary education could be considered as an opportunity for psychological growth and might play a meaningful role in educational identity development during adolescence. In the present study, we aimed to examine how adolescents differ in their educational identity development across the normative transition from secondary to tertiary education in the Netherlands, and if differences between classes could be described at the socio-demographic, academic, individual, and relational level. METHOD: The present study conducted parallel process piecewise Latent Class Growth Analyses in a sample of 685 Dutch participants (47.0% girls, Mage = 17.29 years old at the time of transition). Longitudinal data from adolescent (bi)annual surveys were centered around the final year of secondary school, with 4 years before the final year and 4 years after. RESULTS: Heterogeneity in the development of identity commitment and reconsideration across the transition was best classified by a 4-class solution. These four classes were labelled Increasing Self-Certainty, Stable Self-Certainty, Post-Transition Uncertainty, and Enduring Uncertainty. Adolescents' patterns of identity development were meaningfully associated with sociodemographic, academic, individual, and relational characteristics. CONCLUSION: The present study discusses the merits of taking a person-centered approach, which indicated adaptive development for the majority of adolescents but also captured distinct patterns of struggles in educational identity development across the transition for a sizable minority.

Polygenic Risk for Major Depression Interacts with Parental Criticism in Predicting Adolescent Depressive Symptom Development.

Research has focused more and more on the interplay between genetics and environment in predicting different forms of psychopathology, including depressive symptoms. While the polygenic nature of depressive symptoms is increasingly recognized, only few studies have applied a polygenic approach in gene-by-environment interaction (G × E) studies. Furthermore, longitudinal G × E studies on developmental psychopathological properties of depression are scarce. Therefore, this 6-year longitudinal community study examined the interaction between genetic risk for major depression and a multi-informant longitudinal index of critical parenting in relation to depressive symptom development from early to late adolescence. The sample consisted of 327 Dutch adolescents of European descent (56% boys; Mage T1 = 13.00, SDage T1 = 0.44). Polygenic risk for major depression was based on the Hyde et al. (Nature Genetics, 48, 1031-1036, 2016) meta-analysis and genetic sensitivity analyses were based on the 23andMe discovery dataset. Latent Growth Models suggested that polygenic risk score for major depression was associated with higher depressive symptoms across adolescence (significant main effect), particularly for those experiencing elevated levels of critical parenting (significant G × E). These findings highlight how polygenic risk for major depression in combination with a general environmental factor impacts depressive symptom development from early to late adolescence.

Daily Identity Dynamics in Adolescence Shaping Identity in Emerging Adulthood: An 11-Year Longitudinal Study on Continuity in Development.

According to identity theory, short-term day-to-day identity exploration and commitment processes are the building blocks for long-term development of stable commitments in emerging adulthood. This key assumption was tested in a longitudinal study including 494 individuals (43% girls, Mage T1 = 13.31 years, range 11.01-14.86 years) who were followed from adolescence into emerging adulthood, covering ages 13 to 24 years. In the first five years, adolescents reported on their daily identity processes (i.e., commitment, reconsideration and in-depth exploration) across 75 assessment days. Subsequently, they reported on their identity across four (bi-) annual waves in emerging adulthood. Findings confirmed the existence of a dual-cycle process model of identity formation and identity maintenance that operated at the within-person level across days during adolescence. Moreover, individual differences in these short-term identity processes in adolescence predicted individual differences in identity development in emerging adulthood. Specifically, those adolescents with low daily commitment levels, and high levels of identity reconsideration were more likely to maintain weak identity commitments and high identity uncertainty in emerging adulthood. Also, those adolescents characterized by stronger daily changes in identity commitments and continuing day-to-day identity uncertainty maintained the highest identity uncertainty in emerging adulthood. These results support the view of continuity in identity development from short-term daily identity dynamics in adolescence to long-term identity development in emerging adulthood.

Transactional Links Between Social Anxiety Symptoms and Parenting Across Adolescence: Between- and Within-Person Associations.

This 4-year longitudinal multi-informant study examined between- and within-person associations between adolescent social anxiety symptoms and parenting (parental psychological control and autonomy support). A community sample of 819 adolescents (46.1% girls; Mage T1  = 13.4 years) reported annually on social anxiety symptoms and both adolescents and mothers reported on parenting. Between-person associations suggested that adolescent social anxiety symptoms were associated with higher adolescent- and mother-reported psychological control and lower mother-reported autonomy support. At the within-person level, however, mothers reported lower psychological control and higher autonomy support after periods with higher adolescent social anxiety symptoms. Our findings illustrate the importance of distinguishing among between-person and within-person associations and including perceptions of both dyad members in longitudinal research concerning parenting and adolescent mental health.

Parental Age and Offspring Childhood Mental Health: A Multi-Cohort, Population-Based Investigation.

To examine the contributions of maternal and paternal age on offspring externalizing and internalizing problems, this study analyzed problem behaviors at age 10-12 years from four Dutch population-based cohorts (N = 32,892) by a multiple informant design. Bayesian evidence synthesis was used to combine results across cohorts with 50% of the data analyzed for discovery and 50% for confirmation. There was evidence of a robust negative linear relation between parental age and externalizing problems as reported by parents. In teacher-reports, this relation was largely explained by parental socio-economic status. Parental age had limited to no association with internalizing problems. Thus, in this large population-based study, either a beneficial or no effect of advanced parenthood on child problem behavior was observed.

A 6-Year Longitudinal Study of Adolescents and Mothers Depression Symptoms and Their Perception of Support and Conflict.

Interpersonal theories of adolescent depression assume that adolescent and maternal depression symptoms affect adolescent and maternal perceptions of their relationship quality. However, little attention has been given to examining potential bidirectional prospective associations between both adolescent and maternal perceptions of the mother-adolescent relationship and adolescent and maternal depression symptoms across adolescence. We hypothesized that the longitudinal associations between adolescent and maternal depression symptoms and adolescent and maternal perception of conflict and support in the mother-adolescent relationship would be bidirectional. In this 6-year longitudinal study, 497 adolescents (Mage = 13.03) and their mothers participated. Each year both adolescents and their mothers completed questionnaires of their depression symptoms and their perception of conflict and support in the mother-adolescent relationship. Structural equation modelling cross-lagged panel models were constructed and analyzed. The cross-lagged panel models found bidirectional longitudinal associations between adolescent depressive symptoms and higher adolescent-reported conflict and lower adolescent-reported support. In contrast, maternal depressive symptoms were only unidirectionally associated with higher maternal-reported conflict, lower maternal-reported support and higher adolescent depression symptoms. Finally, positive bidirectional longitudinal associations were found between adolescent-reported and maternal-reported conflict, and between adolescent-reported and maternal-reported support. The findings of this study are discussed in relation to Interpersonal Psychotherapy for Depressed Adolescents (IPT-A).

Anxiety in Early Adolescence: Heterogeneous Developmental Trajectories, Associations with Risk Factors and Depressive Symptoms.

This study aimed: (1) to identify heterogeneous trajectories of anxiety symptoms in early adolescence; (2) to analyze the relationships between risk factors and identified trajectories; (3) to study the association between anxiety symptom trajectories and depression symptom course. Anxiety and depressive symptoms of 825 participants (44.40% boys; mean initial age = 13.01, SD = 0.56) was assessed every 6 months over an 18-month period. Trajectory identification relied on latent-variable approach. As a result, 2-4 trajectories were identified for social phobia (SP), generalized anxiety (GA) and panic symptoms, revealing at least a low-symptom course and a trajectory of elevated symptoms (at-risk trajectory). Being girl and sibling cohabitation were related to at-risk trajectories, and a course of low effortful control and heightened negative affectivity. Finally, SP and GA symptoms were related to heightened depressive symptom courses. Relevant implications towards tailored prevention and intervention are highlighted to promote a healthy development across adolescence.

Goal-Directed Correlates and Neurobiological Underpinnings of Adolescent Identity: A Multimethod Multisample Longitudinal Approach.

This multimethod multisample longitudinal study examined how neurological substrates associated with goal directedness and information seeking are related to adolescents' identity. Self-reported data on goal-directedness were collected across three biannual waves in Study 1. Identity was measured one wave later. Study 1 design and measurements were repeated in Study 2 and extended with structural brain data (nucleus accumbens [NAcc] and prefrontal cortex gray matter volume [PFC]), collected across three biannual waves. Study 1 included 497 adolescents (Mage T1  = 13.03 years) and Study 2 included 131 adolescents (Mage T1  = 14.69 years). Using latent growth curve models, goal directedness, NAcc, and PFC volume predicted a stronger identity one wave later. These findings provide crucial new insights in the underlying neurobiological architecture of identity.

Individual differences in anxiety trajectories from Grades 2 to 8: Impact of the middle school transition.

This study examined the impact of the middle school transition on general anxiety trajectories from middle childhood to middle adolescence, as well as how youths' individual vulnerability and exposure to contextual stressors were associated with anxiety trajectories. Participants were 631 youth (47% boys, M age = 7.96 years at Time 1), followed for 7 successive years from second to eighth grade. Teachers reported on youths' individual vulnerability to anxiety (anxious solitude) in second grade; youth reported on their anxiety in second to eighth grade and aspects of their social contexts particularly relevant to the school transition (school hassles, peer victimization, parent-child relationship quality, and friendship quality) in sixth to eighth grade. The results revealed two subgroups that showed either strongly increasing (5%) or decreasing (14%) levels of anxiety across the transition and two subgroups with fairly stable levels of either high (11%) or low (70%) anxiety over time. Youth in the latter two subgroups could be distinguished based on their individual vulnerability to anxiety, whereas youth with increasing anxiety reported more contextual stressors and less contextual support than youth with decreasing anxiety. In sum, findings suggest that the middle school transition has the potential to alter developmental trajectories of anxiety for some youth, for better or for worse.

Origins of narcissism in children.

Narcissism levels have been increasing among Western youth, and contribute to societal problems such as aggression and violence. The origins of narcissism, however, are not well understood. Here, we report, to our knowledge, the first prospective longitudinal evidence on the origins of narcissism in children. We compared two perspectives: social learning theory (positing that narcissism is cultivated by parental overvaluation) and psychoanalytic theory (positing that narcissism is cultivated by lack of parental warmth). We timed the study in late childhood (ages 7-12), when individual differences in narcissism first emerge. In four 6-mo waves, 565 children and their parents reported child narcissism, child self-esteem, parental overvaluation, and parental warmth. Four-wave cross-lagged panel models were conducted. Results support social learning theory and contradict psychoanalytic theory: Narcissism was predicted by parental overvaluation, not by lack of parental warmth. Thus, children seem to acquire narcissism, in part, by internalizing parents' inflated views of them (e.g., "I am superior to others" and "I am entitled to privileges"). Attesting to the specificity of this finding, self-esteem was predicted by parental warmth, not by parental overvaluation. These findings uncover early socialization experiences that cultivate narcissism, and may inform interventions to curtail narcissistic development at an early age.

When Parents' Praise Inflates, Children's Self-Esteem Deflates.

Western parents often give children overly positive, inflated praise. One perspective holds that inflated praise sets unattainable standards for children, eventually lowering children's self-esteem (self-deflation hypothesis). Another perspective holds that children internalize inflated praise to form narcissistic self-views (self-inflation hypothesis). These perspectives were tested in an observational-longitudinal study (120 parent-child dyads from the Netherlands) in late childhood (ages 7-11), when narcissism and self-esteem first emerge. Supporting the self-deflation hypothesis, parents' inflated praise predicted lower self-esteem in children. Partly supporting the self-inflation hypothesis, parents' inflated praise predicted higher narcissism-but only in children with high self-esteem. Noninflated praise predicted neither self-esteem nor narcissism. Thus, inflated praise may foster the self-views it seeks to prevent.

Clear Self, Better Relationships: Adolescents' Self-Concept Clarity and Relationship Quality With Parents and Peers Across 5 Years.

This study examined reciprocal associations between adolescents' self-concept clarity (SCC) and their relationship quality with parents and best friends in a five-wave longitudinal study from age 13 to 18 years. In all, 497 adolescents (57% boys) reported on their SCC and all informants (i.e., adolescents, both parents, and adolescents' best friends) reported on support and negative interaction. Within-person cross-lagged analyses provided systematic evidence for both parent effects and child effects, with the direction of effects being strongly dependent on the relational context. For example, higher maternal support predicted higher adolescent SCC, supporting a parent effects perspective, whereas higher SCC predicted lower paternal negative interaction, supporting a child effects perspective. Peer effects on adolescent SCC were not consistently found across adolescent and best friend reports.

Longitudinal associations between social anxiety symptoms and cannabis use throughout adolescence: the role of peer involvement.

There appear to be contradicting theories and empirical findings on the association between adolescent Social Anxiety Disorder (SAD) symptoms and cannabis use, suggesting potential risk as well as protective pathways. The aim of this six-year longitudinal study was to further examine associations between SAD symptoms and cannabis use over time in adolescents from the general population, specifically focusing on the potential role that adolescents' involvement with their peers may have in these associations. Participants were 497 Dutch adolescents (57 % boys; M age = 13.03 at T1), who completed annual self-report questionnaires for 6 successive years. Cross-lagged panel analysis suggested that adolescent SAD symptoms were associated with less peer involvement 1 year later. Less adolescent peer involvement was in turn associated with lower probabilities of cannabis use as well as lower frequency of cannabis use 1 year later. Most importantly, results suggested significant longitudinal indirect paths from adolescent SAD symptoms to cannabis use via adolescents' peer involvement. Overall, these results provide support for a protective function of SAD symptoms in association with cannabis use in adolescents from the general population. This association is partially explained by less peer involvement (suggesting increased social isolation) for those adolescents with higher levels of SAD symptoms. Future research should aim to gain more insight into the exact nature of the relationship between anxiety and cannabis use in adolescents from the general population, especially regarding potential risk and protective processes that may explain this relationship.

Mother and adolescent expressed emotion and adolescent internalizing and externalizing symptom development: a six-year longitudinal study.

In expressed emotion (EE) theory, it is held that high EE household environments enhance adolescent psychopathological distress. However, no longitudinal study has been conducted to examine if either the mother's EE or the adolescent's perception of EE predicts adolescent internalizing and externalizing symptom dimensions (an EE effect model) or vice versa (psychopathological effect model) together in one model. To unravel the reciprocal influences of maternal and adolescent perceived EE to adolescent internalizing and externalizing symptom dimensions, we tested two (i.e., one for internalizing and one for externalizing) cross-lagged panel models. In this study, it was found that both internalizing and externalizing symptom dimensions predicted the adolescent's perception of maternal EE as well as the mother's own rated EE criticism over time. The findings of this study should give both researchers and therapists a reason to reevaluate only using the EE effects model assumption in future EE studies.

Heterogeneity in development of adolescent anxiety disorder symptoms in an 8-year longitudinal community study.

In this study, we prospectively examined developmental trajectories of five anxiety disorder symptom dimensions (generalized anxiety disorder, panic disorder, school anxiety, separation anxiety disorder, and social anxiety disorder) from early to late adolescence in a community sample of 239 adolescents, assessed annually over 8 years. Latent growth modeling indicated different developmental trajectories from early into late adolescence for the different anxiety disorder symptoms, with some symptoms decreasing and other symptoms increasing over time. Sex differences in developmental trajectories were found for some symptoms, but not all. Furthermore, latent class growth analysis identified a normal developmental profile (including a majority of adolescents reporting persistent low anxiety disorder symptoms over 8 years) and an at-risk developmental profile (including a minority of adolescents reporting persistent high anxiety disorder symptoms over 8 years) for all of the anxiety disorder symptom dimensions except panic disorder. Additional analyses longitudinally supported the validity of these normal and at-risk developmental profiles and suggested differential associations between different anxiety disorder symptom dimensions and developmental trajectories of substance use, parenting, and identity development. Taken together, our results emphasize the importance of examining separate dimensions of anxiety disorder symptoms in contrast to a using a global, one-dimensional approach to anxiety.
