Organized afterschool activities as a developmental context for children and adolescents.

The last 40 years have been marked by a growing appreciation of organized afterschool activities as a developmental context, with evidence that these activities are linked to academic, social, and behavioral outcomes at least in the short term. In this chapter, we focus on research that builds on these earlier advances to extend afterschool research in two areas that are critical to the future of this field. First, we feature research that examines organized activities longitudinally from kindergarten through the end of high school, enabling us to study organized activities in relation to academic, social-emotional, behavioral, and health outcomes in both the short-run and long-run, including into adulthood. We then turn to a second advance: research focused on organized activities that serve minoritized children and adolescents. These studies identify the barriers minoritized youth often face and how activities can be designed to support their positive development, including efforts to provide culturally responsive programming. Promising directions for future research are presented in a third section.

Promoting positive youth development in rural communities: Integrating social work, psychology, and education.

Considering the peculiar socio-cultural background and developmental obstacles encountered by rural youth in China, the study examines the necessity of adopting an integrated strategy that brings together social work, psychology, and education to promote positive youth development. This research intends to fill the gap by explaining the impact of these factors on community engagement and youth development in China. Targeted programs were also suggested according to the needs of rural youth in China. The respondents of the study comprised 350 young people, whose age ranged from 15 to 24 years, living in different rural areas of the country. The structured questionnaire was designed to collect the data using a convenience sampling technique. Structural Equation Modeling (SEM) was applied as the analysis tool using IBM SPSS AMOS software. The results show that social work and education have a significant impact on community engagement and positive youth development. The findings also reveal that psychology positively influences community engagement. Community engagement was seen to mediate the relationships between social work, psychology, education, and positive youth development. The policymakers and practitioners can fully use the interrelationships between social work, psychology, and education to create a more comprehensive approach that considers the specific characteristics of rural youth in China. Additionally, highlighting community engagement as a mediator also explores the opportunity for bottom-up initiatives and community efforts to instigate favorable youth outcomes in the countryside.

Systematic review and meta-analysis of developmental assets scales: A study protocol for psychometric properties.

BACKGROUND AND AIMS: Application of developmental assets, one of existing Positive Youth Development (PYD) frameworks, has gained momentum in research, policy formulations, and interventions, necessitating the introduction of the most efficient scales for this framework. The present study protocol aims to conduct a systematic review and meta-analysis of developmental assets scales to document the underlying logic, objectives, and methodologies earmarked for the identification, selection, and critical evaluation of these scales. METHODS AND MATERIALS: In accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P), the intended search will encompass databases of PubMed, Scopus, Web of Knowledge, and PsycINFO, spanning from the inception of 1988 to 1st of April 2024. The review will include articles published published in English language focusing on individuals aged 10 to 29 years and reporting at least one type of reliability or validity of developmental assets scales. The review process will be in compliance with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN), and the overall quality of evidence will be determined using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) guidelines. DISCUSSION: This comprehensive assessment aims to identify potential biases in prior research and offer guidance to scholars regarding the optimal scales for developmental assets in terms of validity, reliability, responsiveness, and interpretability The evidence-based appraisal of the scales strengths and limitations is imperative in shaping future research, enhancing their methodological rigor, and proposing refinements to existing instruments for developmental assets.

Internet use and adolescent development in rural China: A scoping review protocol of research landscape and gaps.

INTRODUCTION: In the digital era, the Internet has become a necessity in adolescents' daily lives. Many studies globally are exploring the influences of Internet use on adolescent development, but they focus on the negative impacts of simplistic "screen time" on adolescents' physical and mental health, rather than both positive and negative influences of multifaceted Internet use on multidimensional adolescent development. Specifically in rural China, adolescents live in disadvantageous and marginalizing contexts, and Internet use is widespread among this population. However, knowledge on Internet use and adolescent development in rural China is fragmented. It is still unclear in what ways Internet use would bring benefits or risks for Chinese rural adolescents' healthy growth. Therefore, the objective of this scoping review is to identify the current research landscape, gaps, and future directions in rural China contexts. It aims to provide a comprehensive overview of elements, findings, and limitations in existing empirical studies on the influences of Internet use on adolescent development in rural China. MATERIALS AND METHODS: The standard for conducting this scoping review is the five-stage model proposed by Arksey and O'Malley, and the reporting standard is the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: Extension for Scoping Reviews (PRISMA-ScR). The overall research question is: What are the influences of Internet use on adolescent development in rural China? In consultation with librarians, to locate articles, subject headings (controlled vocabularies) and textwords (keywords) in article titles, abstracts, and author-assigned keywords will be searched in APA PsycInfo (psychology), China National Knowledge Infrastructure (interdisciplinary), Communication Abstracts (media and communication), Education Source (education), MEDLINE (public health), Social Services Abstracts (social work), Social Work Abstracts (social work), and Sociological Abstracts (sociology). The review process via Covidence will consist of two sequential steps based on inclusion/exclusion criteria: the title and abstract review and the full-text review. Then study characteristics and research findings will be charted, and the results will be analyzed and synthesized quantitatively and qualitatively via visualizations and narratives, guided by the typological frameworks of Internet use and adolescent development. DISCUSSION: The scoping review will be a pioneering review to inform the current research landscape and gaps in the Internet use influences on adolescent development in rural China. It will advance the research agenda on this issue conceptually, theoretically, and empirically. In addition, it can provide contextual implications for designing prevention and intervention programs.

The role of family conflict and cohesion in adolescents' social responsibility: Emotion regulation ability as a mediator.

The social context is crucial for the adolescent development of self-regulatory skills and social responsibility. To understand the role of social context in adolescent development, the present study examined family predictors (i.e., family cohesion and conflict) of social responsibility, with emotion regulation ability as a mediating process. A total of 828 Chinese adolescents (35.6% female; mean age = 13.92 years, SD = 1.34) were recruited from major Chinese cities, including Hong Kong and Macau. Path analysis revealed that emotion regulation ability mediated the relation between family factors (i.e., family cohesion and family conflict) and social responsibility. That is, the ability to regulate emotions serves as a process between family factors and social responsibility. More specifically, family cohesion was positively associated with emotion regulation ability, whereas family conflict was negatively associated with emotion regulation ability. In turn, emotion regulation ability was positively associated with social responsibility. The results suggested that the family environment and adolescent's emotion regulation ability are important contextual and intrapersonal factors contributing to their development of social responsibility. As an implication, policymakers and practitioners might allocate resources to enrich positive family interactions and cultivate emotional competency to support adolescents' development of social responsibility.

Are factors that predict conversion to psychosis associated with initial transition to a high risk state? An adolescent brain cognitive development study analysis.

OBJECTIVE: Previous work suggests that cognitive and environmental risk factors may predict conversion to psychosis in individuals at clinical high risk (CHRs) for the disorder. Less clear, however, is whether these same factors are also associated with the initial emergence of the high risk state in individuals who do not meet current threshold criteria for being considered high risk. METHOD: Here, using data from the Adolescent Brain Cognitive Development (ABCD) study, we examined associations between factors previously demonstrated to predict conversion to psychosis in CHRs with transition to a "high risk" state, here defined as having a distress score between 2 and 5 on any unusual thought content question in the Prodromal Questionnaire-Brief Child version. Of a sample of 5237 children (ages 11-12) studied at baseline, 470 transitioned to the high-risk state the following year. A logistic regression model was evaluated using age, cognition, negative and traumatic experiences, decline in school performance, and family history of psychosis as predictors. RESULTS: The overall model was significant (χ2 = 100.89, R2 = 0.042, p < .001). Significant predictors included number of negative life events, decline in school performance, number of trauma types, and verbal learning task performance. CONCLUSIONS: These results suggest that factors that predict conversion in CHR teenagers are also associated with initial emergence of a "high-risk" state in preadolescents. Limitations regarding the degree to which model factors and outcome in this study parallel those used in previous work involving psychosis risk in older teenagers are discussed.

The role (and limits) of developmental neuroscience in determining adolescents' autonomy rights: The case for reproductive and voting rights.

Neuroscientific evidence documenting continued neural development throughout adolescence has been leveraged in advocacy for more lenient treatment of adolescents in the criminal justice system. In recent years, developmental science, including neuroscience, has progressed and enabled more nuanced interpretations of what continuing neural development in adolescence likely means functionally for adolescents' capabilities. However, oversimplified interpretations equating continuing neural development to overall "immaturity" are frequently used to make the case that adolescents should have fewer legal rights to make decisions on their own behalf, including regarding reproductive and voting rights. Here we address ongoing debates about adolescents' autonomy rights and whether such rights should be expanded or restricted. We review extant neuroscientific and developmental research that can inform these debates. We call for: (1) a more nuanced application of developmental neuroscience to specific rights issues in specific contexts; (2) additional research designed to inform our understanding of the developmental benefits or harms of rights-based policies on young people over time; and (3) the grounding of developmental neuroscientific research on adolescents within a human rights framework. We offer suggestions to developmental and neuroscience scholars on how to discuss the science of adolescent development with those seeking guidance in their design of law and policy.

A framework for integrating neural development and social networks in adolescence.

Adolescence is a developmental period characterized by increasingly complex and influential peer contexts. Concurrently, developmental changes in neural circuits, particularly those related to social cognition, affective salience, and cognitive control, contribute to individuals' social interactions and behaviors. However, while adolescents' behaviors and overall outcomes are influenced by the entirety of their social environments, insights from developmental and social neuroscience often come from studies of individual relationships or specific social actors. By capturing information about both adolescents' individual relations and their larger social contexts, social network analysis offers a powerful opportunity to enhance our understanding of how social factors interact with adolescent development. In this review, we highlight the relevant features of adolescent social and neural development that should be considered when integrating social network analysis and neuroimaging methods. We focus on broad themes of adolescent development, including identity formation, peer sensitivity, and the pursuit of social goals, that serve as potential mechanisms for the relations between neural processes and social network features. With these factors in mind, we review the current research and propose future applications of these methods and theories.

COVID-19 lockdown effects on adolescent brain structure suggest accelerated maturation that is more pronounced in females than in males.

Adolescence is a period of substantial social-emotional development, accompanied by dramatic changes to brain structure and function. Social isolation due to lockdowns that were imposed because of the COVID-19 pandemic had a detrimental impact on adolescent mental health, with the mental health of females more affected than males. We assessed the impact of the COVID-19 pandemic lockdowns on adolescent brain structure with a focus on sex differences. We collected MRI structural data longitudinally from adolescents prior to and after the pandemic lockdowns. The pre-COVID data were used to create a normative model of cortical thickness change with age during typical adolescent development. Cortical thickness values in the post-COVID data were compared to this normative model. The analysis revealed accelerated cortical thinning in the post-COVID brain, which was more widespread throughout the brain and greater in magnitude in females than in males. When measured in terms of equivalent years of development, the mean acceleration was found to be 4.2 y in females and 1.4 y in males. Accelerated brain maturation as a result of chronic stress or adversity during development has been well documented. These findings suggest that the lifestyle disruptions associated with the COVID-19 pandemic lockdowns caused changes in brain biology and had a more severe impact on the female than the male brain.

Cultural Values Influence the Developmental Trajectory of Resistance to Social Influence Over the Course of Adolescence.

The opinions of peers are among the most potent factors influencing human decision-making. Research conducted in Western societies suggests that individuals become more resistant to peer influence from late adolescence to adulthood. It is unknown whether this developmental trajectory is universal across cultures. Through two cross-national studies, we present consistent self-report and behavioral evidence for culturally distinct developmental trajectories of resistance to peer influence (RPI). Our findings from the US samples replicated prior findings that reported increasing RPI. Yet, data from the Chinese participants were better fitted using a nonlinear model, displaying a U-shaped trajectory with lowest RPI levels at around 20 years old. In contrast to the long-held belief that increasing RPI from adolescence to early adulthood is a universal developmental trait, we propose that this developmental trajectory may depend on cultural context.

Growing up to be mature and confident? The longitudinal interplay between the Big Five and self-esteem in adolescence.

Adolescence is a formative life phase for the development of personality characteristics. Although past findings suggest Big Five traits alongside self-esteem as indicators for successful development, little is known about their longitudinal interplay. We addressed this research gap by integrating data from three longitudinal studies (NT1 = 1,088; Mage = 16.02 years, 72% female). We apply continuous time modeling to investigate longitudinal associations between Big Five traits and self-esteem in a period of up to 1 year. Results illustrate four main findings: First, rank-order stabilities were overall high for all personality characteristics. Second, longitudinal associations between Big Five traits and self-esteem were reciprocal for extraversion, neuroticism, and openness but one-sided for agreeableness and conscientiousness on self-esteem. Effects peaked within the first month and mostly faded after 2 months. Third, the majority of cross-effects were similar in size; however, the effect from neuroticism on later values of self-esteem was stronger than vice versa. Fourth, most effects were robust against influences of gender, age, and study characteristics. Analyses with acquaintance-reports supported the results but suggested stronger effects that lasted longer than effects of self-reports. We conclude that the development of personality characteristics acts as possible sources of development for each other. All in all, the interplay between Big Five and self-esteem development appears reciprocal for some traits but was most often driven by Big Five traits. We integrate our findings into three contrasting theoretical perspectives and discuss the importance of time for a better understanding of personality development.

Evidence of a developmental shift in the nature of attachment representations: a longitudinal taxometric investigation of secure base script knowledge from middle childhood into adolescence.

Prior research suggests that secure base script knowledge is categorically distributed in middle childhood but becomes dimensionally distributed from late adolescence onward, potentially indicating a developmental shift in the nature of secure base script knowledge. Secure base script knowledge may initially be sparse, giving rise to categorical individual differences, while increased relational experiences later in development might contribute to more elaborated secure base script knowledge and dimensional individual differences. However, the cross-sectional nature of prior research limits inferences about developmental changes. To address this, we conducted a three-year, three-wave longitudinal study with a Western European sample transitioning from middle childhood to adolescence. At Wave 1 (n = 599, Mage = 10.30), secure base script knowledge was categorically distributed. By Wave 2 (n = 435, Mage = 11.30), distribution was ambiguous, and by Wave 3 (n = 370, Mage = 12.09), individual differences were dimensional. These results suggest a developmental shift in secure base script knowledge during the transition into adolescence.

Black youths' ethnic and racial identity development from childhood to emerging adulthood.

This qualitative study employed a retrospective inquiry design to trace changes in the course of ethnic and racial identity (ERI) development of 20 African American college students (18-22 years old) attending a large, predominantly White university in the Midwestern United States. Through interviews, participants recalled life experiences that they considered crucial to their understanding of their own ERI in childhood, adolescence, and emerging adulthood. Using longitudinal qualitative analysis, three distinct pathways of ERI development were identified: consolidating (no change to the understanding they developed earlier in life), cumulative (successive additions or expansions to their current understanding of their own ERI), and transformative (their ERI trajectory is qualitatively altered by a turning point event). Results revealed that the development of ERI components is influenced by the interplay of contextual, individual, and developmental factors, along with the ongoing meaning-making of identity-relevant experiences. Findings lend empirical support for adopting a lifespan approach to ERI development, demonstrating ERI development as a dynamically interactive and continuous process.

How adolescents learn to build social bonds: A developmental computational account of social explore-exploit decision-making.

Building social bonds is a critical task of adolescence that affords opportunities for learning, identity formation, and social support. Failing to develop close relationships in adolescence hinders adult interpersonal functioning and contributes to problems such as loneliness and depression. During adolescence, increased reward sensitivity and greater social flexibility both contribute to healthy social development, yet we lack a clear theory of how these processes interact to support social functioning. Here, we propose synthesizing these two literatures using a computational reinforcement learning framework that recasts how adolescents pursue and learn from social rewards as a social explore-exploit problem. To become socially skilled, adolescents must balance both their efforts to form individual bonds within specific groups and manage memberships across multiple groups to maximize access to social resources. We draw on insights from sociological studies on social capital in collective networks and neurocognitive research on foraging and cooperation to describe the social explore-exploit dilemma faced by adolescents navigating a modern world with increasing access to diverse resources and group memberships. Our account provides important new directions for examining the dynamics of adolescent behavior in social groups and understanding how social value computations can support positive relationships into adulthood.

Trust in adolescence: Development, mechanisms and future directions.

Trust is the glue of society. While the trust we place in close others is crucial for our wellbeing, trust in strangers is important to fulfill needs that families and friends cannot provide. Adolescence is an important phase for the development of trust in strangers, because the social world of adolescents expands tremendously. We provide an overview of the development of trust in adolescence by reviewing studies that used the trust game, an experimental paradigm to measure trust between dyads during monetary exchange. We start from the notion that trust is a form of social reinforcement learning in which prior beliefs about the trustworthiness of others are continuously updated by new information. Within this framework, development in adolescence is characterized by increasing uncertainty of prior beliefs, a greater tolerance of uncertainty, and a greater tendency to seek and use new information. Accordingly, there is evidence for an increase in initial trust and better adaptation of trust during repeated interactions. Childhood psychological and social-economic adversity may impact this development negatively. To further our understanding of these individual differences, we suggest ways in which the trust game can be enriched to capture trust dilemmas that are relevant to youth with diverse backgrounds.

Wanting to matter and learning to care: A neurodevelopmental window of opportunity for (Pro) social learning?

Wanting to matter-to feel socially recognized, appreciated, and capable of actions that benefit others-represents a fundamental motivation in human development. The motivational salience of mattering appears to increase in adolescence. Evidence suggests this is related to pubertal increases in the incentive salience for gaining social value and personal agency. This can provide a useful heuristic for understanding motivational proclivities (i.e. wanting to matter) that influence action-outcome learning as young adolescents are exploring and learning how to navigate increasingly complex social and relational environments. Adolescence also brings new capacities, motives, and opportunities for learning to care about and contribute to the benefit of others. Together, these create a window of opportunity: a sensitive period for learning to gain salient feelings of mattering through caring prosocial actions and valued societal contributions. Successfully discovering ways of mattering by doing things that matter to others may contribute to formative socio-emotional learning about self/other. Advances in understanding these social and relational learning processes and their neurodevelopmental underpinnings can inform strategies to improve developmental trajectories of social competence and wellbeing among adolescents growing up in a rapidly changing and increasingly techno-centric world.

Identifying developmental changes in functional brain connectivity associated with cognitive functioning in children and adolescents with ADHD.

Youth diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) often show deficits in various measures of higher-level cognition, such as, executive functioning. Poorer cognitive functioning in children with ADHD has been associated with differences in functional connectivity across the brain. However, little is known about the developmental changes to the brain's functional properties linked to different cognitive abilities in this cohort. To characterize these changes, we analyzed fMRI data (ADHD = 373, NT = 106) collected while youth between the ages of 6 and 16 watched a short movie-clip. We applied machine learning models to identify patterns of network connectivity in response to movie-watching that differentially predict cognitive abilities in our cohort. Using out-of-sample cross validation, our models successfully predicted IQ, visual spatial, verbal comprehension, and fluid reasoning in children (ages 6 - 11), but not in adolescents with ADHD (ages 12-16). Connections with the default mode, memory retrieval, and dorsal attention were driving prediction during early and middle childhood, but connections with the somatomotor, cingulo-opercular, and frontoparietal networks were more important in middle childhood. This work demonstrated that machine learning approaches can identify distinct functional connectivity profiles associated with cognitive abilities at different developmental stages in children and adolescents with ADHD.

Human adolescent brain similarity development is different for paralimbic versus neocortical zones.

Adolescent development of human brain structural and functional networks is increasingly recognized as fundamental to emergence of typical and atypical adult cognitive and emotional proodal magnetic resonance imaging (MRI) data collected from N [Formula: see text] 300 healthy adolescents (51%; female; 14 to 26 y) each scanned repeatedly in an accelerated longitudinal design, to provide an analyzable dataset of 469 structural scans and 448 functional MRI scans. We estimated the morphometric similarity between each possible pair of 358 cortical areas on a feature vector comprising six macro- and microstructural MRI metrics, resulting in a morphometric similarity network (MSN) for each scan. Over the course of adolescence, we found that morphometric similarity increased in paralimbic cortical areas, e.g., insula and cingulate cortex, but generally decreased in neocortical areas, and these results were replicated in an independent developmental MRI cohort (N [Formula: see text] 304). Increasing hubness of paralimbic nodes in MSNs was associated with increased strength of coupling between their morphometric similarity and functional connectivity. Decreasing hubness of neocortical nodes in MSNs was associated with reduced strength of structure-function coupling and increasingly diverse functional connections in the corresponding fMRI networks. Neocortical areas became more structurally differentiated and more functionally integrative in a metabolically expensive process linked to cortical thinning and myelination, whereas paralimbic areas specialized for affective and interoceptive functions became less differentiated, as hypothetically predicted by a developmental transition from periallocortical to proisocortical organization of the cortex. Cytoarchitectonically distinct zones of the human cortex undergo distinct neurodevelopmental programs during typical adolescence.

Social identity development and religious discrimination among Muslim American youth.

The present study investigated the development of social identity centrality dimensions (i.e., Muslim, ethnic, and American identity centrality) among Muslim American youth as well as associations between religious discrimination and social identity centrality trajectories. Data were collected once annually from 2015 to 2017 with 220 Muslim American youth (M = 14.20, SD = 0.94) in the Midwest United States (girls = 53.2%; boys = 42.3%; missing = 4.5%). Participants were Arab (62.3%), Somali (15.9%), and African American (8.6%), among other ethnic groups (less than 2%). Latent growth curve models indicated that Muslim and ethnic identity centrality displayed negative trajectories and that American identity centrality increased over time. Surprisingly, religious discrimination was not associated with social identity centrality trajectories. This research suggests that Muslim American youths' minoritized social identities develop similarly, whereas youths' American social identity develops differently than these identities.

Associations between growth, maturation and injury in youth athletes engaged in elite pathways: a scoping review.

OBJECTIVE: To describe the evidence pertaining to associations between growth, maturation and injury in elite youth athletes. DESIGN: Scoping review. DATA SOURCES: Electronic databases (SPORTDiscus, Embase, PubMed, MEDLINE and Web of Science) searched on 30 May 2023. ELIGIBILITY CRITERIA: Original studies published since 2000 using quantitative or qualitative designs investigating associations between growth, maturation and injury in elite youth athletes. RESULTS: From an initial 518 titles, 36 full-text articles were evaluated, of which 30 were eligible for final inclusion. Most studies were quantitative and employed prospective designs. Significant heterogeneity was evident across samples and in the operationalisation and measurement of growth, maturation and injury. Injury incidence and burden generally increased with maturity status, although growth-related injuries peaked during the adolescent growth spurt. More rapid growth in stature and of the lower limbs was associated with greater injury incidence and burden. While maturity timing did not show a clear or consistent association with injury, it may contribute to risk and burden due to variations in maturity status. CONCLUSION: Evidence suggests that the processes of growth and maturation contribute to injury risk and burden in elite youth athletes, although the nature of the association varies with injury type. More research investigating the main and interactive effects on growth and maturation on injury is warranted, especially in female athletes and across a greater diversity of sports.
