Feeling anxious and being engaged in a warming world: climate anxiety and adolescents' pro-environmental behavior.

Background: Climate anxiety is increasingly prevalent among adolescents worldwide. Are climate-anxious adolescents prone to engage in pro-environmental behavior? Or might the association between climate anxiety and pro-environmental be curvilinear, such that high levels of climate anxiety become 'paralyzing'? And do these associations depend on whether adolescents believe that, with effort, the worst impacts of climate change can still be prevented?

Methods: We addressed these questions in three studies (two preregistered; combined N = 2,211), conducted across two countries. We used cross-sectional and longitudinal methods, and various measures of climate anxiety and pro-environmental behavior.

Parental psychological control and children's self-esteem: A longitudinal investigation in children with and without oppositional defiant problems.

Oppositional defiant problems are among the most prevalent psychological problems among children and adolescents from China and across the world. Still little is understood about how self-esteem, in conjunction with parenting experiences, develops in children with oppositional defiant problems. We addressed this gap of knowledge in a two-year longitudinal study.

Longitudinal neural and behavioral trajectories of charity contributions across adolescence.

This study examined the development of prosocial charity donations and neural activity in the ventral striatum when gaining rewards for self and for charity. Participants 10-22 years (95% European heritage) participated in three annual behavioral-fMRI waves (T1: n = 160, T2: n = 167, T3: n = 175). Behaviorally, donations to charity as measured with an economic Dictator Game increased with age.

Longitudinal associations between social media use, mental well-being and structural brain development across adolescence.

Youth of today grow up in a digital social world but the effects on well-being and brain development remain debated. This study tracked longitudinal associations between structural brain development, social media use and mental well-being. The study demonstrated two pathways of heterogeneity in brain development.

Dynamics of Identity Development in Adolescence: A Decade in Review.

One of the key developmental tasks in adolescence is to develop a coherent identity. The current review addresses progress in the field of identity research between the years 2010 and 2020. Synthesizing research on the development of identity, we show that identity development during adolescence and early adulthood is characterized by both systematic maturation and substantial stability.

"Wild Years": Rock Music, Problem Behaviors and Mental Well-being in Adolescence and Young Adulthood.

Adolescent preferences for non-mainstream types of rock music can be markers of adolescent problem behaviors, but no study has ever investigated whether this relationship continues into adulthood. In a six-wave study, 900 Dutch adolescents were followed from ages 12 to 21 (Mage T1 12.4, 51.

Mood and emotional reactivity of adolescents during the COVID-19 pandemic: short-term and long-term effects and the impact of social and socioeconomic stressors.

Adolescence is a formative period for socio-emotional development which is threatened by the COVID-19 pandemic. The current longitudinal study examined two aims: (1) the short- and long-term effects of the pandemic on young people's mood (i.e.

On Imbalance of Impulse Control and Sensation Seeking and Adolescent Risk: An Intra-individual Developmental Test of the Dual Systems and Maturational Imbalance Models.

Heterogeneity in development of imbalance between impulse control and sensation seeking has not been studied until now. The present study scrutinized this heterogeneity and the link between imbalance and adolescent risk. Seven-wave data of 7,558 youth (50.

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, M T1 = 13.31 years, range 11.

Longitudinal associations between structural prefrontal cortex and nucleus accumbens development and daily identity formation processes across adolescence.

We tested whether adolescents with daily high identity uncertainty showed differential structural brain development across adolescence and young adulthood. Participants (N = 150, M 15.92 years) were followed across three waves, covering 4 years.

Modeling Individual Differences in Brain Development.

Within the field of developmental cognitive neuroscience, there is an increasing interest in studying individual differences in human brain development in order to predict mental health outcomes. So far, however, most longitudinal neuroimaging studies focus on group-level estimates. In this review, we highlight longitudinal neuroimaging studies that have moved beyond group-level estimates to illustrate the heterogeneity in patterns of brain development.

Linking identity and depressive symptoms across adolescence: A multisample longitudinal study testing within-person effects.

This multisample longitudinal study examined the directionality of effects between identity exploration and commitment processes and depressive symptoms across adolescence. We compared two theoretical perspectives. According to the vulnerability model, identity uncertainty predicts depressive symptoms, whereas the scar model holds that depressive symptoms play into identity uncertainty.

Identity Structure and Processes in Adolescence: Examining the Directionality of Between- and Within-Person Associations.

Developing a stable and coherent identity structure (i.e., a synthesized sense of self that can support self-directed decision making) represents a lifelong task.

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.

Identity uncertainty and commitment making across adolescence: Five-year within-person associations using daily identity reports.

A central assumption of identity theory is that adolescents reconsider current identity commitments and explore identity alternatives before they make new commitments in various identity domains (Erikson, 1968; Marcia, 1966). Yet, little empirical evidence is available on how commitment and exploration dynamics of identity formation affect each other across adolescence at the within-person level. Therefore, the current study (N = 494, Mage Time 1 = 13.

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.

"Snooping" as a Distinct Parental Monitoring Strategy: Comparisons With Overt Solicitation and Control.

Parents can use solicitation (asking questions) and control (disclosure rules) to obtain information about adolescents, but only if youths comply. Snooping might uncover additional information, but also strongly violates privacy expectations. Three studies of parents and adolescents examined distinctions between snooping, solicitation, and control.

The quest for identity in adolescence: Heterogeneity in daily identity formation and psychosocial adjustment across 5 years.

Identity formation is one of the key developmental tasks in adolescence. According to Erikson (1968) experiencing identity uncertainty is normative in adolescence. However, empirical studies investigating identity uncertainty on a daily basis are lacking.

Assessment of identity during adolescence using daily diary methods: Measurement invariance across time and sex.

The aim of this study was to assess measurement invariance of adolescents' daily reports on identity across time and sex. Adolescents (N = 497; mean age = 13.32 years at Time 1, 56.

Child personality facets and overreactive parenting as predictors of aggression and rule-breaking trajectories from childhood to adolescence.

This study examined trajectories of aggression and rule breaking during the transition from childhood to adolescence (ages 9-15), and determined whether these trajectories were predicted by lower order personality facets, overreactive parenting, and their interaction. At three time points separated by 2-year intervals, mothers and fathers reported on their children's aggression and rule breaking (N = 290, M age = 8.8 years at Time 1).
