RESUMO

The global COVID-19 pandemic illustrates the importance of a close partnership between public health and juvenile justice systems when responding to communicable diseases. Many setting-specific obstacles must be navigated to respond effectively to limit disease transmission and negative health outcomes while maintaining necessary services for youth in confinement facilities. The response requires multidisciplinary expertise and collaboration to address unique considerations. Public health mitigation strategies must balance the risk for disease against the negative effects of restrictions. Key aspects of the COVID-19 response in the juvenile justice system of Colorado, USA, involved establishing robust communication and data reporting infrastructures, building a multidisciplinary response team, adapting existing infection prevention guidelines, and focusing on a whole-person health approach to infection prevention. We examine lessons learned and offer recommendations on pandemic emergency response planning and managing a statewide public health emergency in youth confinement settings that ensure ongoing readiness.

RESUMO

BACKGROUND: In Latin America, interventions aimed at adolescents' health suffer from a shortfall of investment and lack of sustainability. Nurses, as an integral part of health services and systems, can lead the implementation and development of public health policies to improve adolescent health. OBJECTIVE: To identify and analyze the role of nurses in the development and implementation of public policies and in the provision of health care to adolescents in Colombia, Ecuador, and Peru. METHODS: The research was carried out in three phases: a documentary analysis, an online survey, and semi-structured focus groups. A total of 48 documents were analyzed, 288 nurses participated in the survey, and 29 nurses participated in the focus groups. RESULTS: State policies aim to guarantee rights, with special protection for children and adolescents. It is an incremental process, with greater involvement of civil society and governments. Participants reported a lack of synergy between law and practice, as well as differences in regulatory compliance in rural areas and in populations of different ethnicities and cultures. Their perception was that the protection of adolescents is not specifically enshrined in the legal bases and regulatory structures of the countries, meaning that there are both protective factors and tensions in the regulatory framework. While nurses are highly committed to different actions aimed at adolescents, their participation in policy development and implementation is low, with barriers related to a lack of specialized training and working conditions. CONCLUSIONS: Given nurses' involvement in different actions aimed at adolescents, they could play a fundamental role in the development of policies for adolescents and ensure their effective implementation. Policymakers should consider revising the budget to make compliance viable, incorporating and using monitoring indicators, and increasing the involvement of educational institutions and the community.

RESUMO

While aspiring to be a diverse and global science, developmental science continues to be dominated by EuroAmerican epistemologies, researchers, and communities in its published scholarship. Adolescents in communities across Africa, Asia, the Middle East, and Latin America comprise 85% of the world's adolescent population, and yet their experiences and perspectives are marginalized in our science. Adolescents in the Majority World live in highly diverse social, cultural, political, economic, educational and healthcare contexts that contribute to their development, and we have much to learn from their experiences. This article situates the marginalization of the global majority within coloniality embedded in developmental science. The article describes the impetus for this special issue Towards a decolonial developmental science and the process of putting it together, along with providing an overview of the 18 articles in this collection that push us towards decoloniality. The special issue serves as a call to transform developmental science to be decolonial by empowering adolescent development in Majority World communities to take center stage. Adolescent development research from Majority World communities has the potential to challenge the knowledge base generated from Minority World samples, contributing to a science that is comprehensive, inclusive, and can inform prevention and intervention efforts to support the well-being of adolescents globally.

RESUMO

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, while perseverance and adaptability were linked to higher levels of competence, confidence, and character, consistency was associated with lower levels of competence and confidence six months later. Results highlight the importance of grit's dimensions in facilitating PYD characteristics among adolescents, especially efficacy-related Cs (competence and confidence). Theoretical and practical implications in promoting adolescent thriving and well-being are discussed.

RESUMO

INTRODUCTION: As adolescents leave high school, plans for the future are of great importance. Future orientation reflects positive thoughts regarding further education, employment, and family life. While future orientation has been found to affect behavior problems, the influence of behavior problems on future orientation is mainly unknown. Positive parent-child and peer relations may boost positive outlooks, but the interplay of behavior problems and social relations for future orientation remains to be studied. METHODS: Participants were 485 adolescents, 54% girls, living in Mid-Sweden. At age 15, parents and adolescents rated ADHD- and internalizing symptoms, parents rated ODD-symptoms, and adolescents rated their relationship with parents and peers. At age 18, adolescents rated future orientation regarding education, employment, and family, and reported on delinquent acts. RESULTS: Low levels of inattention symptoms and of delinquency were important for all higher future orientation aspects. In contrast, higher levels of hyperactive-impulsive symptoms were associated with more positive outlooks on work and family life. Relationships with parents and peers were stronger predictors of future outlooks, compared with behavior problems. There were few interaction effects of behavioral symptoms and social relationship quality. CONCLUSIONS: Behavior problems in middle adolescence may negatively affect future outlooks. However, positive social relations, especially relations with peers, seem more important for optimistic views than behavior problems and thus may have a compensatory effect. The clinical implications should be to address the young person's social world, in the case of misgivings about the future, also in the presence of problematic behaviors.

RESUMO

BACKGROUND: In the context of rural Bihar where few women work outside the home, what scope do adolescent girls and young women have to transition into wage work and careers? While the mobility of girls is still widely restricted to secure their marriageability, the spread of higher schooling and the internet has inflated aspirations and levelled them out across boys, girls and social classes. METHODS: The present study drew on 45 focus group discussions and 73 in-depth interviews among adolescent girls and young women and related stakeholders to develop 32 cases of transitioning girls across four districts of rural Bihar in India. The qualitative data were collected in 2022 and analysed using a combination of thematic and comparative narrative analyses. RESULTS: The analysis identified some common features of transitioning girls and their pathways. Many girls had been forced by circumstance-household shocks or chronic poverty-to earn money, thereby building their skills and self-efficacy. Others were from families where progressive values ensured their mobility and exposure. Yet others transitioned "by stealth." But all girls had the backing of at least one parent and all had to learn to navigate public space while safeguarding their reputations. By researching actual pathways (rather than distant dreams), the study identifies a variety of transition outcomes, including "good" jobs as teachers, nurses, and police officers, "low entry" jobs in factories and new services, and full-time businesses built from scratch. CONCLUSION: The paper suggests that interventions be designed separately for these distinct outcomes and that efforts are best directed towards girls already "self-transitioning" and demonstrating the requisite resolve and self-efficacy.

RESUMO

INTRODUCTION: Debate about the precise role of social media use (SMU) in the mental health of today's adolescents is still ongoing. The present study adds to the literature by focusing on adolescents' experiences during SMU and in their offline activities through the lens of basic psychological needs, which are central to self-determination theory. METHODS: To examine the joint and supplementary effects of need-experiences in the offline and SMU domain (i.e., SMU satisfaction, offline satisfaction, SMU frustration, offline frustration) on several indicators of adolescents' mental health (i.e., vitality, life satisfaction, sleep quality, anxiety, and depression), polynomial regression analyses were used. Three cross-sectional samples were collected in Belgium, including early to mid-adolescents during the COVID-pandemic (Sample 1; N = 447; Mage = 14.26; 54.4% female) as well as postpandemic (Sample 2; N = 179, Mage = 15.25; 54.2% female), and among college students in postpandemic times (Sample 3; N = 4977; Mage = 20.72; 69.1% female). RESULTS: The results showed that need-experiences common to both domains were a robust factor associated with mental health. This finding was obtained across all samples and outcomes, with need satisfaction playing a beneficial and need frustration a harmful role. We further found that offline need-experiences serve as a more crucial predictor of adolescents' mental health than need experiences on social media. CONCLUSIONS: Adolescents' experiences of need satisfaction and need frustration on social media and in offline activities are central to their mental health. However, only relying on SMU as a single source of need satisfaction may not be recommended, given that offline experiences seem to be more decisive.

RESUMO

INTRODUCTION: Negative urgency (the tendency to act rashly when experiencing negative emotions) is a robust risk factor for a number of problem behaviors, including early adolescent drinking. Little is known about the factors that precede the development of negative urgency, and hence the full etiology of this component of risk. The current study aimed to investigate the possibility that facets of childhood maladaptive emotion socialization (the tendency for children's expressions of emotions to be met with punishment, minimized, or invoke a reaction of distress from their parents/caretakers) increases risk for the development of negative urgency and drinking behavior. METHOD: Self-report measures of negative urgency, subfacets of maladaptive emotion socialization, and drinking behavior were collected during the 2021-2022 academic year from a sample of 428 high school students (mean age = 14.7, SD = 0.09, 44% female), assessed twice over the course of a semester, reflecting a 4-month longitudinal window. RESULTS: Distress emotion socialization predicted increases in negative urgency, minimizing predicted decreases in negative urgency, and punitive did not provide significant prediction. Additionally, results found that higher levels of both negative urgency and distress emotion socialization increased adolescents' likelihood of having tried alcohol. These processes were invariant across race and gender. CONCLUSIONS: The present study may inform the future creation of prevention and intervention efforts aimed at reducing maladaptive emotion socialization and increasing adaptive emotion socialization. Successful reductions in negative urgency as a consequence of increased adaptive emotion socialization may then lead to decreases in adolescent drinking and other impulsigenic behaviors.

RESUMO

INTRODUCTION: Civic engagement (CE) in adolescence is associated with a higher level of engagement in adulthood and is reported to be beneficial to youth's development and societal well-being. Parents are among the most influential factors in adolescents' lives. This study examined the associations between parents' own civic participation, their negative beliefs toward youth CE and their child's future CE. While prior research documented positive associations between parental civic behaviors and youth CE, the role of parental negative beliefs has remained unexplored and could act as an additional barrier to adolescents' CE. METHODS: A total of 234 adolescents (65% girls; mean age = 13.77) and their parents (79% mothers; mean age = 44.20), residing in the Canadian province of Quebec from 2016 to 2019, were recruited for this cross-sectional study. Parents completed measures of their civic activities and their negative beliefs regarding youth CE. Adolescents completed measures of future civic attitudes and behaviors. RESULTS: Hierarchical regressions revealed significant positive cross-sectional associations between parental civic behaviors and their child's future civic attitudes and behaviors. However, parental negative beliefs toward youth CE were negatively associated with youths' future civic attitudes and behaviors, even after considering parental civic behaviors and family socioeconomic status. Adolescents' age did not moderate these relationships. CONCLUSION: These findings highlight the significant role that parents could play in shaping CE of future generations. Interventions promoting youth CE should thus target both adolescents and their parents.

RESUMO

The onset of mental health issues frequently starts during adolescence, where one third of adolescents who are 14 years and younger receive a mental health diagnosis. The state of youth mental health is a major public health concern. The EMPOWER project was developed during the COVID-19 pandemic to address youth mental health. The EMPOWER project is a partnership between two after-school programs and an academic mental health hospital in Toronto, Canada, that aims to bolster youth mental well-being. In this Practice Note, we share our community-based participatory research process of how we built the EMPOWER partnership and highlight our lessons learned so far. Through EMPOWER, we aim to codesign, deliver, and evaluate a scalable, evidence-based, and community-informed youth mental wellness curriculum that will be implemented in after-school programs.

RESUMO

Adolescents are sexually assaulted at remarkably high rates. Adolescents are also unique given the specific dynamics of adolescent sexual assault, their current stage in human development, their limited legal standing and rights, and their experiences navigating postassault services and resources. While literature exists within each of these domains, it is somewhat disconnected and overlooks how adolescents are often relegated to the margins in research and practice. The purpose of this integrative review is to (1) provide a more complete understanding of adolescent sexual assault and survivors' nuanced needs; (2) frame adolescent survivors as a too-often-overlooked oppressed group that researchers and responders must consider and center in their work, lest contribute to their further marginalization; and (3) inspire and orient social justice-minded scholar activists to various action steps to take to center and prioritize adolescents in research and practice. Through our intersectional feminist approach, we offer specific action steps for social justice-minded scholar activists to recenter adolescents in their research and practice.

RESUMO

Research on parental burnout has focused more on its antecedents than on its consequences. Burned-out parents may experience a series of behavioral changes, negatively affecting their children's physical and mental development. This study examined the effects of primary caregivers' parental burnout on adolescents' development and the mediating role of negative parenting styles. This study used a time-lagged design, and data were collected at three different time points. Adolescents were asked to identify their primary caregivers, and parents were asked whether they were the primary caregivers of their children. Thereafter, paired data from the children and primary caregivers were collected. A total of 317 junior middle school students (178 boys, Mage = 14.20 ± 0.8 years) and primary caregivers (71 fathers, Mage = 42.20 ± 4.53 years) from Henan province participated. Primary caregivers' parental burnout was positively associated with negative parenting styles, and negative parenting styles mediated the relationship between parental burnout and adolescent development. From the perspective of prevention-focused interventions, it is necessary to focus on preventing the occurrence of parental burnout. Further, parents should try to avoid using abusive behaviors toward their children and neglecting them.

RESUMO

BACKGROUND: Research has demonstrated an association between elevated systemic inflammation and changes in brain function. Affective areas of the brain involved in processing threat (e.g., amygdala) and reward (e.g., nucleus accumbens) appear to be sensitive to inflammation. Early-life stress, such as experiencing low socioeconomic status (SES), may also potentiate this association, but relevant evidence has come primarily from cross-sectional studies of brain function. It is unclear whether similar associations are present between early-life stress, inflammation, and brain structure, particularly in typically developing populations. METHODS: We recruited and assessed 50 adolescents (31 females/19 males) from the community (mean [SD] age = 15.5 [1.1] years, range = 13.1-17.5 years) and examined in exploratory analyses whether changes in C-reactive protein (ΔCRP) from blood spots predict changes in gray matter volume (ΔGMV) in the bilateral amygdala and nucleus accumbens over a 2-year period. We also investigated whether experiencing early-life stress, operationalized using a comprehensive composite score of SES disadvantage at the family and neighborhood levels, significantly moderated the association between ΔCRP and ΔGMV. RESULTS: We found that ΔCRP was negatively associated with Δamygdala GMV (i.e., increasing CRP levels were associated with decreasing amygdala volume; ß = -0.84, p = .012). This effect was stronger in youths who experienced greater SES disadvantage (ß = -0.56, p = .025). CONCLUSIONS: These findings suggest that increases in systemic inflammation are associated with reductions in amygdala GMV in adolescents, potentially signaling accelerated maturation, and that these neuroimmune processes are compounded in adolescents who experienced greater SES disadvantage. Our findings are consistent with theoretical frameworks of neuroimmune associations and suggest that they may influence adolescent neurodevelopment.

RESUMO

BACKGROUND: Exposure to violence has severe and lasting effects on development. Despite the body of research examining childhood exposures to violence and victimization, developmental outcomes during early adolescence are poorly understood. OBJECTIVE: To synthesize existing research on the effects of violence exposure on early adolescent development (youth 9-14 years old) and highlight areas for future research. METHOD: We conducted a systematic search of PubMed, CINAHL, Web of Science, Scopus, and EMBASE for articles published between 2012 and 2023. Included articles focused on violence exposure related to experiencing or observing community violence, witnessing domestic violence and/or being the victim of chronic physical abuse. RESULTS: Twenty-eight articles spanning four developmental domains were included: behavioral, biological, neurological, and social development. Behaviorally, violence exposure posed significant effects on both internalizing and externalizing symptoms. Biologically, violence exposure was strongly associated with advanced epigenetic age, accelerated puberty, and insomnia. Neurologically, violence exposure had significant associations with both structural and functional differences in the developing brain. Socially, violence exposure was related to poor school engagement, peer aggression, and low social support. CONCLUSION: This systematic review highlights varying effects of violence exposure on early adolescent development. The gaps presented should be addressed and implemented into clinical practice via evidence-based policies and procedures to ensure successful transition to adulthood.

RESUMO

Background: In early adolescence, youth are highly prone to suicidal behaviours. Identifying modifiable risk factors during this critical phase is a priority to inform effective suicide prevention strategies. Aims: To explore the risk and protective factors of suicidal behaviours (ie, suicidal ideation, plans and attempts) in early adolescence in China using a social-ecological perspective. Methods: Using data from the cross-sectional project 'Healthy and Risky Behaviours Among Middle School Students in Anhui Province, China', stratified random cluster sampling was used to select 5724 middle school students who had completed self-report questionnaires in November 2020. Network analysis was employed to examine the correlates of suicidal ideation, plans and attempts at four levels, namely individual (sex, academic performance, serious physical illness/disability, history of self-harm, depression, impulsivity, sleep problems, resilience), family (family economic status, relationship with mother, relationship with father, family violence, childhood abuse, parental mental illness), school (relationship with teachers, relationship with classmates, school-bullying victimisation and perpetration) and social (social support, satisfaction with society). Results: In total, 37.9%, 19.0% and 5.5% of the students reported suicidal ideation, plans and attempts in the past 6 months, respectively. The estimated network revealed that suicidal ideation, plans and attempts were collectively associated with a history of self-harm, sleep problems, childhood abuse, school bullying and victimisation. Centrality analysis indicated that the most influential nodes in the network were history of self-harm and childhood abuse. Notably, the network also showed unique correlates of suicidal ideation (sex, weight=0.60; impulsivity, weight=0.24; family violence, weight=0.17; relationship with teachers, weight=-0.03; school-bullying perpetration, weight=0.22), suicidal plans (social support, weight=-0.15) and suicidal attempts (relationship with mother, weight=-0.10; parental mental illness, weight=0.61). Conclusions: This study identified the correlates of suicidal ideation, plans and attempts, and provided practical implications for suicide prevention for young adolescents in China. Firstly, this study highlighted the importance of joint interventions across multiple departments. Secondly, the common risk factors of suicidal ideation, plans and attempts were elucidated. Thirdly, this study proposed target interventions to address the unique influencing factors of suicidal ideation, plans and attempts.

RESUMO

Objective: After remaining stable for many years, the prevalence of depression among adolescents increased over the past decade, particularly among girls. In this study, we used longitudinal data from a cohort of high school students to characterize sex-specific trajectories of depressive symptoms during this period of increasing prevalence and widening gender gap in adolescent depression. Method: Using data from the Health and Happiness Cohort, a longitudinal 8-wave study of high school students residing in Los Angeles County from 2013 to 2017 (N = 3,393), we conducted a multiple-group, latent class growth analysis by sex to differentiate developmental trajectories in depressive symptoms scores measured by the Center for Epidemiological Studies- Depression (CES-D) scale (range, 0-60). Results: A 4-class solution provided the best model fit for both girls and boys. Trajectories among girls included low stable (35.1%), mild stable (42.8%), moderate decreasing (16.2%), and high arching (5.9%). Trajectories among boys included low stable (49.2%), mild increasing (34.7%), moderate decreasing (12.2%), and high increasing (3.9%). Average scores consistently exceeded or crossed the threshold for probable depression (≥16). Across comparable sex-specific trajectory groups, the average CES-D scores of girls were higher than those of boys, whose average scores increased over time. Conclusion: In a diverse cohort of students in Los Angeles County, depressive symptom trajectories were comparable to prior time periods but with a higher proportion of students in trajectories characterized by probable depression. Trajectories differed by sex, suggesting that future research should consider differential severity and onset of depression between boys and girls.

RESUMO

INTRODUCTION: Youth media guidelines in Canada and the United States recommend that bedrooms should remain screen-free zones. This study aims to verify whether bedroom screens at age 12 years prospectively predict academic and social impairment by age 17 years. METHODS: Participants were from the Quebec Longitudinal Study of Child Development birth cohort (661 girls and 686 boys). Linear regression analyses estimated associations between having a bedroom screen (television or computer) at age 12 years and selfreported overall grades, dropout risk, prosocial behaviour and likelihood of having experienced a dating relationship in the past 12 months at age 17 years, while adjusting for potential individual and family confounding factors. RESULTS: For both girls and boys, bedroom screens at age 12 years predicted lower overall grades (B = -2.41, p ≤ 0.001 for boys; -1.61, p ≤ 0.05 for girls), higher dropout risk (B = 0.16, p ≤ 0.001 for boys; 0.17, p ≤ 0.001 for girls) and lower likelihood of having experienced a dating relationship (B = -0.13, p ≤ 0.001 for boys; -0.18, p ≤ 0.001 for girls) at age 17. Bedroom screens also predicted lower levels of prosocial behaviour (B = -0.52, p ≤ 0.001) at age 17 years for boys. CONCLUSION: The bedroom as an early adolescent screen-based zone does not predict long-term positive health and well-being. Pediatric recommendations to parents and youth should be more resolute about bedrooms being screen-free zones and about unlimited access in private exposures in childhood.

RESUMO

Adolescence has been hypothesized to be a critical period for the development of human association cortex and higher-order cognition. A defining feature of critical period development is a shift in the excitation: inhibition (E/I) balance of neural circuitry, however how changes in E/I may enhance cortical circuit function to support maturational improvements in cognitive capacities is not known. Harnessing ultra-high field 7 T MR spectroscopy and EEG in a large, longitudinal cohort of youth (N = 164, ages 10-32 years old, 347 neuroimaging sessions), we delineate biologically specific associations between age-related changes in excitatory glutamate and inhibitory GABA neurotransmitters and EEG-derived measures of aperiodic neural activity reflective of E/I balance in prefrontal association cortex. Specifically, we find that developmental increases in E/I balance reflected in glutamate:GABA balance are linked to changes in E/I balance assessed by the suppression of prefrontal aperiodic activity, which in turn facilitates robust improvements in working memory. These findings indicate a role for E/I-engendered changes in prefrontal signaling mechanisms in the maturation of cognitive maintenance. More broadly, this multi-modal imaging study provides evidence that human association cortex undergoes physiological changes consistent with critical period plasticity during adolescence.

RESUMO

Growth patterns and biological milestones in youth sports are key to interpreting the development of young athletes. However, there is no analysis of longitudinal meta-analysis describing the growth of young female athletes. This longitudinal meta-analysis estimated growth curves and age at peak height velocity (PHV) in young female athletes based on anthropometric data from longitudinal studies found in the literature. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, studies with repeated measurements in young female athletes were identified from searches of four databases (MEDLINE, Web of Science, SCOPUS, and SPORTDiscus) without date restrictions through August 2023. We adapted our bias assessment criteria using the Cochrane risk of bias tool for randomized controlled trials as a reference. Bayesian multilevel modeling was used to perform a longitudinal meta-analysis to extract stature growth curves and age at PHV. Fourteen studies met our eligibility criteria. Twenty-one independent samples could be included in the analysis. Conditional on the data and models, the predicted mean age at PHV for female athletes was 11.18 years (90% CI: 8.62; 12.94). When studies were aggregated by sport in the models, the models could not capture sport-specific growth curves for stature and estimate a corresponding age at PHV. We provide the first longitudinal meta-analytic summary of pubertal growth and derive age at PHV in young female athletes. The meta-analysis predicted that age at PHV occurs at similar ages to those in the general pediatric population. The data pool was limited in sports and geographic distribution, emphasizing the need to promote longitudinal research in females across different youth sports contexts.

RESUMO

This study investigated the associations between early parental warmth, harsh discipline, and adolescent depressive symptoms from early to late adolescence, with attention to gender differences in these associations. The sample was drawn from a longitudinal study, the Taiwan Youth Project, including 2,690 Taiwanese adolescents from wave 1 in 2000 (first year in junior high school) to wave 6 (third year in high school) in 2005. The results showed a nonlinear developmental trajectory of adolescent depressive symptoms during the middle- to high-school period. Harsh discipline was associated with the significantly higher initial presence and faster growth rate of depressive symptoms, while parental warmth and monitoring were associated with the significantly lower initial presence of depressive symptoms. In addition, female adolescents displayed a higher initial level of depressive symptoms than males when parents exercised higher levels of monitoring and harsh discipline. Finally, we provided suggestions for practice and research.
