276 to 300 of 838Cortisol and testosterone jointly affect adolescent fairness.
Fairness is crucial in social interactions, shaping relationships and fostering cooperation, especially during adolescence. The developmental period, characterized by significant hormonal changes such as fluctuations in cortisol and testosterone levels, is pivotal for physiological and behavioral maturation. Despite the importance of the hormones, studies investigating their interaction effects on fairness within adolescent populations remain limited. The current study explored adolescent fairness development and how cortisol (bedtime basal cortisol and cortisol awakening response, CAR) and testosterone interacted in strategic and pure fairness towards friends and strangers, using adapted versions of the Ultimatum Game (UG) and Dictator Game (DG), separately, in 381 typically developing adolescents (37 % female, Mage = 14.6 years, SDage = 1.95). As adolescents matured, they increasingly …

Sibling relational aggression: Developmental change and associations with family relationships across adolescence.
Sibling relational aggression is an understudied social and family process that is of developmental significance in adolescence, a period of interpersonal relationship development. This study examined developmental change in sibling relational aggression across adolescence and used multilevel actor-partner independence models to test its longitudinal associations with mother-adolescent, father-adolescent, and sibling relationship qualities. Participants were 196 adolescent (firstborn-secondborn) sibling pairs from predominantly White families who averaged 16.47 years (SD = .80) and 13.88 years (SD = 1.15) of age, respectively, at baseline. Data were collected separately from each sibling during home interviews at three timepoints, each spaced a year apart. Longitudinal growth modeling revealed declines in sibling relational aggression from early to late adolescence. Findings from longitu…

Buenconsejo JU, Datu JAD, Liu D (2024)MEDLINE-indexed journal, not yet read by usJournal of research on adolescence : the official journal of the Society for Research on Adolescence1 citations Does grit predict thriving or is it the other way around? A latent cross-lagged panel model on the triarchic model of grit and the 5Cs of positive youth development.
Grit, defined as passion and perseverance to achieve long-term goals, has been associated with adolescents' optimal academic and psychological functioning. However, the role of grit in adolescents' positive youth development (PYD)-characterized by the 5Cs known as competence, confidence, connection, character, and caring-remains unknown. Using latent cross-lagged panel modeling, this study examined the longitudinal relations between the triarchic model of grit (TMG) dimensions (i.e., perseverance of effort, consistency of interest, and adaptability to situations), and the 5Cs of PYD while controlling for specific socio-demographic covariates (gender, age, SES, and school type). Data were obtained from 1620 Filipino adolescents (Mage = 17.15; SDage = 1.00) in November 2021 and May 2022. Results show that grit dimensions predicted subsequent PYD dimensions, but not vice versa. Specifically…

Screen time and mental health: a prospective analysis of the Adolescent Brain Cognitive Development (ABCD) Study.
Background: Despite the ubiquity of adolescent screen use, there are limited longitudinal studies that examine the prospective relationships between screen time and child behavioral problems in a large, diverse nationwide sample of adolescents in the United States, which was the objective of the current study.
Methods: We analyzed cohort data of 9,538 adolescents (9-10 years at baseline in 2016-2018) with two years of follow-up from the Adolescent Brain Cognitive Development (ABCD) Study. We used mixed-effects models to analyze associations between baseline self-reported screen time and parent-reported mental health symptoms using the Child Behavior Checklist, with random effects adjusted for age, sex, race/ethnicity, household income, parent education, and study site. We tested for effect modification by sex and race/ethnicity.
Results: The sample was 48.8% female and racially/ethnicall…

Disengaging from Evil: Longitudinal Associations Between the Dark Triad, Moral Disengagement, and Antisocial Behavior in Adolescence.
Previous work has identified important correlational linkages between the dark triad of personality (Machiavellianism, psychopathy, and narcissism) and antisocial behavior in adolescence. However, little is known about the longitudinal associations between these personality characteristics and antisocial behavior, and the processes underlying these linkages. We hypothesized positive bidirectional associations between the dark triad and antisocial behavior, and that increases in moral disengagement would underlie these longitudinal associations. In the current study, we examined these hypotheses in 502 Dutch adolescents (51.8% boys, Mage = 13.57, SD = 1.07) across three annual waves. Path models showed that antisocial behavior was positively associated with relative increases in moral disengagement, a general dark personality factor, and Machiavellianism specifically, but not the other wa…

Brief Behavioural Activation (Brief BA) for Adolescent Depression: A Pilot Study.
Background: Depression in adolescence is a common and serious mental health problem. In the UK, access to evidence-based psychological treatments is limited, and training and employing therapists to deliver these is expensive. Brief behavioural activation for the treatment of depression (BATD) has great potential for use with adolescents and to be delivered by a range of healthcare professionals, but there is limited empirical investigation with this group.
Aims: To adapt BATD for depressed adolescents (Brief BA) and conduct a pilot study to assess feasibility, acceptability and clinical effectiveness.
Method: Twenty depressed adolescents referred to the local NHS Child and Adolescent Mental Health service (CAMHs) were offered eight sessions of Brief BA followed by a review around one month later. Self- and parent-reported routine outcome measures (ROMs) were collected at every session.

The Intersection of Emotional and Sociocognitive Competencies with Civic Engagement in Middle Childhood and Adolescence.
Civic developmental theory anticipates connections between normative developmental competencies and civic engagement, but little previous research has directly studied such links. The current study sought to contribute to civic development theory by examining associations between emotional and sociocognitive competencies (empathy, emotion regulation, prosocial moral reasoning, future-orientation) and civic engagement (volunteering, informal helping, political behaviors and beliefs, environmental behaviors, social responsibility values, civic skills). Data came from a geographically and racially diverse sample of 2467 youth (Mage = 13.4, Range: 8-20 years, 56% female). The results indicated that empathy and future-orientation significantly predicted nearly all forms of civic engagement, whereas emotion regulation and prosocial moral reasoning were uniquely associated with specific forms o…

How is Civic Engagement Related to Personal Identity and Social Identity in Late Adolescents and Emerging Adults? A Person-Oriented Approach.
Adolescence and emerging adulthood are periods in life when individuals both question and define their place in society and form their identity. Meanwhile, active youth civic engagement represents a challenge for each democracy. The purpose of this study was to analyze the different forms of civic engagement among late adolescents and emerging adults and how they are related to personal identity and social identity, while adopting an integrative perspective through the lens of a person-oriented approach. The participants were 1217 (62.3% female) 16-24 year-old French students (M age = 19.17; SD age = 1.83). First, derived from cluster analyses, the findings emphasized diversity in civic engagement, from strong civic participation (in different formal and informal ways) to various forms of passivity. Diversity was also highlighted for personal identity and social identity profiles. Seco…

Prosocial Behavior in Adolescence: Gender Differences in Development and Links with Empathy.
Although adolescents' prosocial behavior is related to various positive outcomes, longitudinal research on its development and predictors is still sparse. This 6-wave longitudinal study investigated the development of prosocial behavior across adolescence, and examined longitudinal associations with perspective taking and empathic concern. Participants were 497 adolescents (M age t1 = 13.03 years, 43% girls) who reported on their prosocial behaviors, empathic concern, and perspective taking. The results revealed marked gender differences in the development of prosocial behavior. For boys, levels of prosocial behavior were stable until age 14, followed by an increase until age 17, and a slight decrease thereafter. For girls, prosocial behavior increased until age 16 years and then slightly decreased. Regarding longitudinal associations, empathic concern was consistently related to subsequ…

Stability of Attachment Style in Adolescence: An Empirical Test of Alternative Developmental Processes.
Few studies have examined stability and change in attachment during adolescence. This 5-year longitudinal study (a) examined whether prototype or revisionist developmental dynamics better characterized patterns of stability and change in adolescent attachment (at T1, N = 176; Mage = 14.0 years, SD = 0.9), (b) tested potential moderators of prototype-like attachment stability, and (c) compared attachment stability in adolescence to stability in adulthood. The results supported the prototype model, which assumes that there is a stable, enduring factor underlying stability and change in attachment. Exploratory moderation analyses revealed that family conflict, parental separation or divorce, minority status, and male sex might undermine the prototype-like stability of adolescent attachment. Stability of attachment was lower in adolescence relative to adulthood.

Within-subject neural reactivity to reward and threat is inverted in young adolescents.
Background: As children mature, they become increasingly independent and less reliant on caregiver support. Changes in brain systems are likely to stimulate and guide this process. One mechanistic hypothesis suggests that changes in neural systems that process reward and threat support the increase in exploratory behavior observed in the transition to adolescence. This study examines the basic tenets of this hypothesis by performing functional magnetic resonance imaging (fMRI) during well-established reward and threat processing tasks in 40 children and adolescents, aged 9-15 years.
Method: fMRI responses in the striatum and amygdala are fit to a model predicting that striatal reward and amygdala threat-responses will be unrelated in younger participants (aged 9-12 years), while older participants (aged 13-15 years) will differentially engage these structures.
Results: Our data are consi…

Looking at the dark and bright sides of identity formation: New insights from adolescents and emerging adults in Japan.
The aim of the present study was to gain new insights into the dark and bright sides of identity formation with a sample of 1851 Japanese adolescents and emerging adults, applying a three-dimensional model of identity formation (i.e., commitment, in-depth exploration, and reconsideration of commitment). By means of cluster analysis, we identified five statuses that strongly resembled statues extracted in prior research with Western youth: achievement, foreclosure, moratorium, diffusion, and searching moratorium. We found that each status reported a distinct profile in terms of personality and psychosocial problems. Importantly, we found that the searching moratorium status was adaptive in adolescence but not in emerging adulthood. These results suggest that the five statuses are replicable in Japanese adolescents and emerging adults, and that the searching moratorium status presents a co…

Socioeconomic patterns of overweight, obesity but not thinness persist from childhood to adolescence in a 6-year longitudinal cohort of Australian schoolchildren from 2007 to 2012.
Background: The prevalence of childhood overweight and obesity increased during the 1980s to the late 1990s. The prevalence of obesity is higher in socially and economically disadvantaged communities in most Westernised countries. The purpose of this study was to examine how the socioeconomic gradient in weight status, namely thinness, overweight and obesity, changes over time in a longitudinal cohort of Australian schoolchildren, from 2007-2012.
Methods: 939 Australian children in school grades 2-6 from 10 primary schools initially participated in the study in 2007. Height and weight were directly measured by research assistants each year. Obesity/overweight and thinness were defined by using the International Obesity Task Force BMI cut-offs. Chi-square analyses were used to test associations between categorical variables and linear mixed models were used to estimate whether the differe…

Black adolescents' relationships with natural mentors: associations with academic engagement via social and emotional development.
This study aimed to identify types of natural mentoring relationships that Black adolescents may experience and to connect these relationship types to academic outcomes via social and emotional development. Data were collected from 259 adolescents attending 3 middle schools in a Midwestern metropolitan area. Adolescents reported on whether or not they had a relationship with a natural mentor and answered several questions about characteristics of the relationship, as well as reporting on a number of indicators of positive development. Cluster analyses suggested two different types of natural mentoring relationships among study youth: less connected and more connected. We found that in comparison with youth without a natural mentor, youth who had a more connected natural mentoring relationship had greater student-reported academic engagement via higher social skills and psychological well…

A preliminary investigation of moral reasoning and empathy after traumatic brain injury in adolescents.
Primary objective: Traumatic brain injury (TBI) sustained during childhood can affect a number of socio-cognitive skills; however, little attention has focused on the integrity of moral reasoning in the assessment of post-TBI social sequelae and the role of empathy and intelligence on moral maturity.
Research design: In a quasi-experimental, cross-sectional research design, moral reasoning maturity and empathy in adolescents with mild-to-severe TBI (n = 25) were compared to typically-developing peers (n = 66).
Methods and procedures: Participants were administered the So-Moral and So-Mature, tasks of socio-moral reasoning and maturity, the Index of Empathy for Children and Adolescents, the Wechsler Abbreviated Scale of Intelligence and a demographic questionnaire.
Main outcomes and results: Participants with TBI had significantly lower levels of moral reasoning maturity. Further, adolesc…

Correlates of identity configurations: three studies with adolescent and emerging adult cohorts.
Adolescence and emerging adulthood are two core developmental periods in which individuals can develop a meaningful identity across domains. However, there is a lack of studies exploring correlates of different identity configurations. The purpose of this article was to fill this gap in examining correlates of configurations characterized by identity stability or instability in both ideological and relational domains or identity stability in one domain and instability in the other domain. Three studies were presented. In the first study, we investigated links between identity configurations and internalizing problem behaviors in early and middle adolescents (N=1,891; M (age) =14; 55% female); in the second study, we focused on associations between identity configurations and identity functions in late adolescents and early emerging adults (N=1,085; M (age) =19; 63% female); in the third …

Trajectories of family management practices and early adolescent behavioral outcomes.
Stage-environment fit theory was used to examine the reciprocal lagged relations between family management practices and early adolescent problem behavior during the middle school years. In addition, the potential moderating roles of family structure and of gender were explored. Hierarchical linear modeling was used to describe patterns of growth in family management practices and adolescents' behavioral outcomes and to detect predictors of interindividual differences in initial status and rate of change. The sample comprised approximately 1,000 adolescents between ages 11 years and 15 years. The results indicated that adolescents' antisocial behaviors and substance use increased and their positive behavioral engagement decreased over time. As adolescent age increased, parental knowledge of their adolescent's activities decreased, as did parental rule making and support. The level and ra…

Humans have systematic sex differences in brain-related behavior, cognition, and pattern of mental illness risk. Many of these differences emerge during adolescence, a developmental period of intense neurostructural and endocrine change. Here, by creating "movies" of sexually dimorphic brain development using longitudinal in vivo structural neuroimaging, we show regionally specific sex differences in development of the cerebral cortex during adolescence. Within cortical subsystems known to underpin domains of cognitive behavioral sex difference, structural change is faster in the sex that tends to perform less well within the domain in question. By stratifying participants through molecular analysis of the androgen receptor gene, we show that possession of an allele conferring more efficient functioning of this sex steroid receptor is associated with "masculinization" of adolescent corti…

Meaning in life as a mediator of ethnic identity and adjustment among adolescents from Latin, Asian, and European American backgrounds.
Establishing a sense of life meaning is a primary facet of well-being, yet is understudied in adolescent development. Using data from 579 adolescents (53% female) from Latin American, Asian, and European backgrounds, demographic differences in meaning in life, links with psychological and academic adjustment, and the role of meaning in explaining associations between ethnic identity and adjustment were examined. Although no generational or gender differences were found, Asian Americans reported higher search for meaning than Latin and European Americans. Presence of meaning was positively associated with self-esteem, academic adjustment, daily well-being, and ethnic belonging and exploration, whereas search for meaning was related to lower self-esteem and less stability in daily well-being. Presence of meaning mediated associations between ethnic identity and adjustment, explaining 28-52…

Prosocial involvement as a positive youth development construct: conceptual bases and implications for curriculum development.
Pro-social involvement programmes are significant and important for the healthy growth of adolescents as well as for the development of society. Pro-social involvement of adolescence refers to paid-job, volunteer works, sport and games. It serves the functions of making adolescents aware of and to accept the social norms and moral standard of the society, which would bring positive changes to the adolescents and consequently benefit the society as a whole. Past studies showed that adolescents who participated in pro-social involvement programmes tended to have positive self-perception, more social skills, and less anti-social behaviors. In Hong Kong, professionals in education and social services have fully recognized the benefits of pro-involvement programmes. They have organized multi-level and diverse pro-social involvement programmes and encouraged adolescents to participate. Through…

Prevalence of insomnia symptoms in a general population sample of young children and preadolescents: gender effects.
Objective: Our population-based study examined the prevalence of insomnia symptoms and its sociodemographic, subjective, and polysomnographic (PSG) sleep risk factors in young and preadolescent children.
Methods: We performed a cross-sectional study of 700 children, ages 5-12 years who underwent a 9-h PSG and parent-completed sleep and development questionnaires (Penn State Child Cohort). Insomnia symptoms were defined as parent report of difficulty falling or staying asleep and sleep-disordered breathing (SDB) as an apnea hypopnea index of ≥1.
Results: The prevalence of insomnia symptoms was 19.3% and did not significantly change (20.2%) when children with SDB were excluded. A significant interaction between gender and age revealed that the prevalence of insomnia symptoms was highest in girls ages 11 to 12 years (30.6%). This gender difference was not associated with significant differe…

Puberty Initiates Cascading Relationships Between Neurodevelopmental, Social, and Internalizing Processes Across Adolescence.
Adolescence is a period of dramatic developmental transitions-from puberty-related changes in hormones, bodies, and brains to an increasingly complex social world. The concurrent increase in the onset of many mental disorders has prompted the search for key developmental processes that drive changes in risk for psychopathology during this period of life. Hormonal surges and consequent physical maturation linked to pubertal development in adolescence are thought to affect multiple aspects of brain development, social cognition, and peer relations, each of which have also demonstrated associations with risk for mood and anxiety disorders. These puberty-related effects may combine with other nonpubertal influences on brain maturation to transform adolescents' social perception and experiences, which in turn continue to shape both mental health and brain development through transactional pro…

Does puberty mark a transition in sensitive periods for plasticity in the associative neocortex?
Postnatal brain development is studded with sensitive periods during which experience dependent plasticity is enhanced. This enables rapid learning from environmental inputs and reorganization of cortical circuits that matches behavior with environmental contingencies. Significant headway has been achieved in characterizing and understanding sensitive period biology in primary sensory cortices, but relatively little is known about sensitive period biology in associative neocortex. One possible mediator is the onset of puberty, which marks the transition to adolescence, when animals shift their behavior toward gaining independence and exploring their social world. Puberty onset correlates with reduced behavioral plasticity in some domains and enhanced plasticity in others, and therefore may drive the transition from juvenile to adolescent brain function. Pubertal onset is also occurring e…

Obesity and the pubertal transition in girls and boys.
Childhood obesity has become a major health concern in recent decades, especially with regard to metabolic abnormalities that impart a high risk for future cardiovascular disease. Recent data suggest that excess adiposity during childhood may influence pubertal development as well. In particular, excess adiposity during childhood may advance puberty in girls and delay puberty in boys. Obesity in peripubertal girls may also be associated with hyperandrogenemia and a high risk of adolescent polycystic ovary syndrome. How obesity may perturb various hormonal aspects of pubertal development remains unclear, but potential mechanisms are discussed herein. Insulin resistance and compensatory hyperinsulinemia may represent a common thread contributing to many of the pubertal changes reported to occur with childhood obesity. Our understanding of obesity's impact on pubertal development is in its …
