This study focuses on the relationship between preadolescents and youtubers, with the objective of observing how tweens integrate youtubers as referents of a teen digital culture. From a socio-psychological and communicological perspective, a mixed methodological design was applied to carry out the audience study, which was divided into two parts: a quantitative analysis of the audience via a survey administered to 1,406 eleven-twelve year old students of Catalan Secondary Schools, and a qualitative analysis of the preadolescence audience using three focus groups. The quantitative data was analysed with SPSS and the qualitative data with the help of the Atlas.ti software. The results demonstrate that tweens consider youtubers as referents for entertainment and for closeness to a teen digital culture, but not really as a role models or bearers of values as influencers. Also, preadolescents show some dimensions of Media Literacy, since they recognise youtubers’ commercial strategies and their role as actors and professionals. The study notes gender bias in some aspects, and is an introduction to observation of the social functions of youtubers amongst teenagers, individuals who are in the process of constructing their identity and on the point of becoming young adults. El presente estudio se centra en la relación entre preadolescentes y youtubers, con el objetivo de observar cómo los primeros integran a los youtubers como referentes de una cultura digital juvenil. Desde una perspectiva sociopsicológica y comunicativa, se aplicó un diseño metodológico mixto para llevar a cabo el estudio de audiencia, organizado en dos partes: un análisis cuantitativo de la audiencia a través de un cuestionario administrado a 1.406 estudiantes de once-doce años de institutos en Cataluña, y un análisis cualitativo de la audiencia preadolescente a partir de tres «focus group». Los datos cuantitativos se analizaron con SPSS y los cualitativos con la ayuda del programa Atlas.ti. Los resultados demuestran que los preadolescentes consideran a los youtubers como referentes para el entretenimiento y por su proximidad a una cultura digital juvenil, pero no realmente como modelos o portadores de valores en tanto que «influencers». Además, los preadolescentes muestran alguna dimensión de Alfabetización Mediática, al identificar las estrategias comerciales de los youtubers y sus roles profesionales. El estudio da cuenta de un sesgo de género en algunos aspectos, y resulta una introducción a la observación sobre las funciones sociales de los youtubers entre los adolescentes, personas que están en pleno proceso de construcción de sus identidades y a punto de convertirse en jóvenes adultos.

Purpose: This case study is presented to inform the reader of potential speech, language, cognitive, and emotional characteristics in preadolescent cluttering. Method: This case study describes a 10-year-old boy who started to clutter during preadolescence. The case illustrates that, in some adolescents, cluttering can co-occur with temporary stuttering-like behavior. In this case, signs of disturbances in speech-language production associated with behavioral impulsiveness as a young child were noted. Speech, language, cognitive, and emotional results of the case are reported in detail. Results: The changes in fluency development are reported and discussed within the context of changes in the adolescent brain as well as adolescent cognitive and emotional development. While being unaware of their speech condition before adolescence, during preadolescence, the changes in brain organization lead to an increase in rate and a decrease in speech control. Given that the client had limited understanding of what was occurring, they were at risk of developing negative communication attitudes. Speech-language therapists are strongly advised to monitor children with cluttering signals in the early years of their adolescence. Supplemental Material: https://doi.org/10.23641/asha.21318072

Fruit juice consumption during childhood remains controversial. Here, we evaluated the association between preadolescent 100% fruit juice intake and later adolescent diet quality and body mass index (BMI). We used prospective data over 10 years from the National Growth and Health Study for 1921 black and white girls, ages 9–10 years at baseline, for analyses of diet quality, and 2165 girls for BMI analyses. Statistical analyses included repeated measures analysis of variance and logistic regression models. Girls who drank ≥1.0 cup/day of fruit juice in preadolescence consumed 0.44 cup/day more total fruit in later adolescence than non-juice-drinking girls (p < 0.0001). White and black girls who drank ≥1.25 cups/day in preadolescence were 2.62 (95% CI: 1.35–5.08) and 2.54 (1.27–5.07) times more likely, respectively, to meet the Dietary Guidelines for whole fruit by later adolescence than those with the lowest juice intakes. Further, fruit juice consumption was positively associated with diet quality scores. Overall, girls consuming ≥1.25 cups/day of juice had a BMI in late adolescence that was 1.7 kg/m2 lower than that of non-juice-drinking girls. In conclusion, early adolescent fruit juice intake was positively associated with subsequent whole fruit consumption, better diet quality, and lower BMI in later adolescence.

This paper aims to present the main features of early adolescence today (also known as preadolescence). The paper refers to this age period on three levels: the physical level and sexual maturation, the cognitive level, and the socio-emotional level. Thus, we propose a theoretical approach to the main characteristics of early adolescence, but also the analysis of a series of particularities and challenges specific to this stage of life. Despite the fact that childhood, preadolescence and adolescence are certainly difficult, most young people manage to get through these stages of development due to the relationships with family and friends, motivated by academic success or activities that help them build their personality and self-esteem.

AbstractFour vowel variables are investigated in the speech of 50 rural, nonmigrant children and adolescents aged 6 to 18 years in the Syrian village Oyoun Al-Wadi. Contrary to previous studies, the children initially acquire the urban and later the rural forms of these vowels. This process of acquisition shows the following. First, children show reversal in the acquisition of forms, and thus the rules associated with them; instead of acquiring the local forms first, they acquire the supralocal forms. Second, children can acquire the rules of the second dialect after the age of 8. Third, gender emerges as significant as boys and girls exhibit different linguistic behavior. Fourth, preadolescents emerge as the age group that is most active in building a social identity. Fifth, social-psychological factors motivate the shift from urban to rural forms. These include local identity, gendered social meanings of the variants, and the growth of the children's sociolinguistic competence throughout their preadolescence and adolescence.

OBJECTIVES/GOALS: Irritability, a proneness to anger and frustration, is a transdiagnostic symptom associated with poor mental health outcomes. Levels of irritability vary across development and high-risk trajectories have been observed. This study aims to use machine learning to predict irritability trajectories across the transition to adolescence. METHODS/STUDY POPULATION: Data were from the Adolescent Brain Cognitive Development (ABCD) Study, which is a 10-year longitudinal study that tracks the brain development, cognitive skills, physical health, and psychosocial functioning of a large, national sample starting from preadolescence. The baseline sample consisted of 11,861 9-10-year-old preadolescent youth. Irritability was parent-rated at baseline, 1-year, 2-year, 3-year, and 4-year follow-ups on the Child Behavior Checklist (CBCL) irritability index. Latent class growth analysis (LCGA) was used to determine developmental trajectories of irritability. Two machine learning approaches were applied to develop predictive models of youth irritability developmental trajectories. We used baseline (preadolescent) variables that spanned a wide range of domains. RESULTS/ANTICIPATED RESULTS: Preliminary results fromthe LCGA indicated best support for a four-class model that differentiated growth trajectories in irritability across the transition to adolescence: 1) persistent low irritability (n = 8691, 73.27%), 2) moderate irritability and decreasing (n = 1257, 10.60%), 3) low to moderate irritability and increasing (n = 1295, 10.92%), and 4) chronic high irritability (n = 618, 5.21%). We expect the machine learning analyses to generate predictive models with acceptable accuracy. We hypothesize that the most important predictors in the models will originate from the youth mental health domain, including baseline youth irritability, externalizing symptoms, internalizing symptoms, and oppositional behaviors, and the parent psychopathology domain, particularly parent irritability. DISCUSSION/SIGNIFICANCE: The present study elucidates unique developmental trajectories of irritability and generates predictive models to classify high-risk irritability trajectories using machine learning approaches. Clinicians can use these predictive models to identify at-risk youth and provide early intervention to preadolescents at high risk.

AbstractIn contrast to victimization, prior research on the antecedents and outcomes of bullying perpetration has provided little conclusive knowledge. Some adolescent bullies may be well adjusted and popular among peers, while other bullies are rejected and lack self-control. There is also great variation in the outcomes, with a number of studies (but not all) showing increased risk for externalizing and internalizing problems. We used a developmental framework and data from 2,230 participants of the Dutch Tracking Adolescents’ Individual Lives Survey (TRAILS) to examine bullying perpetration across adolescence, to test the links with various antecedents in preadolescence, and to elucidate the outcomes in early adulthood. Latent growth models indicated significant variance in initial bullying perpetration levels and an overall decrease between pre- and late adolescence. Individual, family, and peer factors were associated with initial levels and partially associated with bullying development over time. Bullying perpetration was linked to later maladjustment and substance use, although only in girls. Finally, bullying perpetration appears to function as an intermediate variable between preadolescent individual, family, and peer risk and substance use more than 10 years later. These results have important implications for understanding the gender-specific nature of bullying perpetration and its outcomes and for demonstrating that bullying carries early risk into adulthood.

Nonsuicidal self-injury (NSSI) affects 15% to 20% of adolescents—disproportionately girls—and is a strong predictor of eventual suicide attempts and suicide. Many girls now initiate NSSI before age 10. These early starters exhibit greater frequency of NSSI, use more diverse methods, and are hospitalized more often than later starters, yet there are no empirically supported prevention programs for preadolescents. Obstacles to prevention include ascertaining who is sufficiently vulnerable and specifying mechanistic intervention targets. Recent research indicates that (a) preadolescent girls with ADHD who are also maltreated are at alarming risk for NSSI and suicide attempts by adolescence and (b) the conjoint effects of these vulnerabilities are sufficiently potent for targeted prevention. Research also indicates that existing interventions are effective in altering child- and family-level mechanisms of NSSI. These interventions alter neurobiological markers of vulnerability, which can be used as proximal efficacy signals of prevention response without waiting for NSSI and suicide attempts to emerge.

I propose the gender gap in delinquency is linked to adolescents’ orientation to gender-normative behavior and empathic development. I use longitudinal data on 1,525 youth from the Denver Youth Survey to analyze relationships among gender, empathy, and delinquency. I find girls exhibit higher levels of empathy across adolescence than do boys, and these differences emerge in preadolescence. Empathy is inversely related to delinquency, and is predictive of fraud and theft, but not violent delinquency. Finally, empathy partially mediates the effect of being male on delinquency. I therefore argue the gender gap in delinquency can be explained—in part—by adherence to gender norms governing empathetic expression.

Purpose: While previous research underscores the important role that neighborhood contexts play for child and adolescent health and well-being, how these neighborhood contexts influence substance use initiation among adolescents from low-income and ethnic minority families has been understudied. Methods: This study is a secondary analysis of data from the Denver Child Study a retrospective survey that uses a natural experiment aimed at assessing neighborhood effects on developmental outcomes of Latinx and African American adolescents (N = 736). Cox cause-specific hazards models were estimated to test: (1) the effects of cumulative exposure to neighborhood social disorder, neighborhood violent and property crime rates, and neighborhood social capital during preadolescence (ages 8–11) on the likelihood of initiating alcohol, cigarette, and marijuana use during adolescence (ages 12–18), after controlling for youth, caregiver, and household factors; and (2) whether the effects of these cumulative neighborhood factors vary by Latinx and African American ethnicity. Results: 5.6% of adolescents in this study initiated cigarette use, 5.4% initiated alcohol use and 5.2% used marijuana for the first time during adolescence. The results indicate that exposure to neighborhood social disorder during preadolescence is a significant risk factor, especially for the initiation of cigarette use (HR = 1.36, 95% CI = 1.062–1.745, p = 0.015) particularly among Latinx adolescents (HR = 1.42, 95% CI = 1.031–1.966, p = 0.032). Conclusions: The findings suggest the need for further research on the relationship between exposure to neighborhood social disorder and adolescent substance use initiation in order to develop and implement community-based prevention and intervention programs to reduce substance use initiation and facilitate healthy adolescent development.

AbstractThe present work combats the problem of violence and aggressive behaviour through mentoring. The theoretical point of view certified studies that highlight various aspects of the problem of violent and aggressive behaviour remediation of preadolescents and adolescents. At present there are no publications that completely synthesize the institutional and normative field of mentoring. The existing publications reference to the regulation regarding the establishment of the mentoring system for teaching staff in education. Thus, the problem of mentoring valorization in combating violent behaviour among preadolescents and adolescents remains unresolved. The viable solution to solving these actual problems of the postmodern world is to focus on the personality value system.

Social anxiety is a common mental disorder with an average age of onset in early adolescence. Current theories focus largely on risk factors that are present from early in life, but reasons for onset of the disorder as youth move into adolescence are rarely discussed. We recently proposed a model of the onset of certain mental disorders during the adolescent years based on characteristics of adolescent development. While this model will require longitudinal testing, the current article establishes concurrent associations between relevant variables in a cohort of 528 preadolescents ( M age = 11.2 years) at baseline. Youth with social anxiety disorder differed significantly from other youth on measures of social comparison (including physical appearance comparisons, self-rated attractiveness, and negative peer comparisons on social media) as well as positive peer connections (including self-reported school belonging, number of friends, victimization, and peer affiliation). A structural equation model showed that symptom levels of social anxiety were directly related to social comparisons and peer connections, as well as indirectly associated with pubertal development and social comparisons. This pattern was not moderated by sex of youth.

IntroductionOur 15-years follow-up ReMIND project aims to re-assess an epidemiological and a clinical sample of adults (Wave 3), who were assessed in preadolescence (Wave 1) and adolescence (Wave 2), to evaluate symptoms trajectories and their relationship with genetic/epigenetic data, environmental risk factors and neuroimaging measures.ObjectivesHere, we depict preliminary results regarding the epidemiological sample.MethodsWe assessed internalizing and externalizing symptoms in 40 italian subjects (25 F) from general population at three waves (W1 mean age: 12±0,82; W2 mean age: 17±0,88, W3 mean age: 28±1), through the Child Behavior Checklist (W1 and W2) or the Adult Self Report (W3), and perinatal risk factors through a socio-anamnestic questionnaire, by a new online platform (MedicalBit). We analyzed symptoms trajectories and their relation with perinatal risk factors through a repeated measures multivariate analysis of variance (rm-MANOVA).Resultsrm-MANOVA results show that high number of perinatal risks was significantly associated with higher internalizing symptomatology in preadolescence but not in adolescence and adult life. The mean difference was 8 T-points. The same trend is evident in adolescence but not in adult age (Graph 1). Perinatal risk factors did not have a significant effect on externalizing symptoms at any time point, despite a non-significant trend is evident (Graph 2).ConclusionsOur preliminary results suggest a trend of increased internalizing symptoms from childhood to adulthood and a significant role of perinatal risk factors in pre-adolescence. Further investigations are necessary to better understand symptoms trajectories and the role of biological and environmental factors.DisclosureNo significant relationships.

Although it is well documented that intrapersonal and interpersonal risk factors are related to the frequency of marijuana use, much less is known about the initiation of marijuana use. This paper reports on a longitudinal study of the personality, family, peer, and ecological predictors of marijuana onset. Survival analysis was applied to a sample of nonusers of illegal drugs, followed from age 9 years to the 20s. The major findings indicate that (a) youngsters who are unconventional are at a higher risk for marijuana initiation; (b) youngsters who associate with peers who use marijuana or who smoke tobacco themselves are at increased risk for marijuana initiation; (c) youngsters who identify with their parents are less likely to begin marijuana use; and (d) the predictors related to marijuana onset emerged during preadolescence, early adolescence, middle adolescence, late adolescence, and the 20s. Results are discussed within the framework of a family interactional perspective of development. Implications for prevention are discussed.

Behavioral interventions on behalf of diabetic women must be based on an understanding of these life span changes. A review of selected articles from the medical and psychological literature that focus on special issues for a diabetic woman during preadolescence, adolescence, and adulthood is presented. Recommendations are made for behavioral interventions with diabetic women in regard to “sick” role adjustment, peer conformity pressures, eating disorders, sexuality, and pregnancy.

Concurrent global events such as political changes, natural disasters, climatic changes, protests, wars, and pandemics are factors that help with defining a generation. What are the characteristics of Generation Z and what are the problems its members face? Preadolescence is a period during which individuals strongly feel the need to reflect deeply on what is happening to them. Several questions arise: “Who am I? Am I a normal person? Am I a competent person? Am I worthy of being loved?”; “How do I manage my emotions (e.g. fear, anger, and sadness)?”. Anxiety and depression disorders are two of the most common issues that arise during adolescence. The project ZETgeneration - Smile, Empathy, Therapy aims to facilitate access to culture for generation Z preadolescents affected by depression disorders, with the help of art and therapy. This is achieved through four contemporary art productions based on interviews and questionnaires conducted with 300 children from Iași. This article, an interdisciplinary perspective between art, education and mental health, explores how cinema, theater, and art therapy can prevent depression and encourage conversations between adults and children on topics related to mental health.

Lung function (LF) has been shown to be associated with asthma risk and its severity. However, the role of LF in the associations between DNAm and AA is unclear, and it is also unknown whether the association between DNAm and AA is consistent with that between DNAm and LF. We address this question through assessing newborn epigenetic features of preadolescence LF and of AA during adolescence, along with their biological pathways and processes. Our study’s primary medical significance lies in advancing the understanding of asthma’s early life origins. By investigating epigenetic markers in newborns and their association with lung function in preadolescence, we aim to uncover potential early biomarkers of asthma risk. This could facilitate earlier detection and intervention strategies. Additionally, exploring biological pathways linking early lung function to later asthma development can offer insights into the disease’s pathogenesis, potentially leading to novel therapeutic targets. Methods: The study was based on the Isle of Wight Birth cohort (IOWBC). Female subjects with DNAm data at birth and with no asthma at age 10 years were included (n = 249). The R package ttScreening was applied to identify CpGs potentially associated with AA from 10 to 18 years and with LF at age 10 (FEV1, FVC, and FEV1/FVC), respectively. Agreement in identified CpGs between AA and LF was examined, along with their biological pathways and processes via the R function gometh. We tested the findings in an independent cohort, the Avon Longitudinal Study of Parents and Children (ALSPAC), to examine overall replicability. Results: In IOWBC, 292 CpGs were detected with DNAm associated with AA and 1517 unique CpGs for LF (514 for FEV1, 436 for FVC, 408 for FEV1/FVC), with one overlapping CpG, cg23642632 (NCKAP1) between AA and LF. Among the IOWBC-identified CpGs, we further tested in ALSPAC and observed the highest agreement between the two cohorts in FVC with respect to the direction of association and statistical significance. Epigenetic enrichment analyses indicated non-specific connections in the biological pathways and processes between AA and LF. Conclusions: The present study suggests that FEV1, FVC, and FEV1/FVC (as objective measures of LF) and AA (incidence of asthma) are likely to have their own specific epigenetic features and biological pathways at birth. More replications are desirable to fully understand the complexity between DNAm, lung function, and asthma acquisition.

Objectives. To assess police contact as a potential adverse childhood experience by measuring its prevalence, nature, and distribution among urban adolescents. Methods. Detailed US population-based data on youth‒police contact were collected in the Fragile Families and Child Wellbeing Study (n = 2478) from 2014 to 2017. Using regression modeling, I assessed adolescents’ police exposure and the magnitude and robustness of racial disparities in police contact. Sensitivity analyses examined disparities by behavior and socioeconomic context. Results. Urban youths are heavily policed, beginning in preadolescence. Exposure to policing is unevenly distributed, with non-White adolescents—particularly Black boys—reporting more, and more aggressive, contact than their White counterparts. Hispanic‒White differences and disparities in girls’ experiences were less pronounced but present, particularly in how intrusive stops were. Intrusion disparities were robust to most behavioral controls, but not observed among youths with higher socioeconomic status. Conclusions. Given extant literature documenting adverse health consequences of police encounters, findings implicate policing as a driver of health disparities in adolescence and throughout the life course. Public health infrastructure dedicated to the prevention and treatment of adverse childhood experiences is well suited for mitigating these harms and inequities.

Objectives. To determine the bone metabolic marker changes from childhood to adolescence and to provide reference values for monitoring bone development in children in Southwest China. Methods. We surveyed 703 participants attending physical examinations from April 2019 and August 2021. Twenty-eight participants were excluded for lack of laboratory tests, and 14 people were excluded for diseases that might affect bone metabolism. A total of 661 children were selected for the study. According to the main developmental periods, the children were divided into preschool, preadolescence, and adolescence groups. Serum bone turnover markers including β-isomerized C-terminal telopeptide of type I collagen (β-CTx), N-terminal midfragment of osteocalcin (N-MID), and procollagen type 1 N-propeptide (P1NP) as well as growth and development indices such as serum calcium (Ca), phosphorus (Pi), alkaline phosphatase (ALP), and vitamin D were measured. The changes in bone metabolism-related markers and the correlations between the indices were analyzed. Results. During the development in boys, the levels of β-CTx and N-MID increased with age from preschool to adolescence, while the levels of P1NP decreased and then increased. In girls, the levels of β-CTx and N-MID plateaued in early adolescence and showed little change in subsequent adolescence, while the levels of P1NP exhibited a downward trend. The correlations between bone metabolism markers and vitamin D were not significant. Conclusions. The levels of bone metabolism markers differed between boys and girls. Reference intervals can be used as essential tools to examine the levels of bone metabolism markers reasonably.

Background: Youth experience a decrease in physical activity (PA) and an increase in sedentary time during adolescence. Better understanding of factors associated with activity levels during preadolescence may inform interventions to minimize decline. This study compared the association of self-efficacy for PA, parent support for PA, and peer support for PA with moderate-to-vigorous PA (MVPA) and sedentary time among 8- to 12-year-old children with body mass index ≥75th percentile. Methods: This study analyzed baseline data from a school-based healthy weight management intervention trial, conducted in metropolitan Minnesota. Self-efficacy for PA, parent support for PA, and peer support for PA were measured by child survey using reliable tools. MVPA and sedentary time were measured using accelerometer. Results: Participants included 114 children; mean age was 9.4 (0.9) years, 51% were females, 55% received public assistance, and 57% were racial/ethnic minorities. Self-efficacy for PA was positively associated with moderate to vigorous PA for girls (β = 1.83, P < .01) and inversely with sedentary time for the total sample (β = −7.00, P = .03). Parent support for PA was positively associated with sedentary time for girls (β = 9.89, P = .04) and the total sample (β = 7.83, P = .04). Conclusions: Interventions for preadolescents with elevated body mass index may improve activity levels by increasing self-efficacy for PA.

Self-esteem is a widely studied concept in the field of psychology and not only,this human component according to the multitudes of researches carried out ends up affecting a wide spectrum of activities carried out by people if they are in an imbalance. I chose this staging of preadolescence in relation to self-esteem and the online environment because I consider this period the most susceptible to changes caused by the environment, regardless of what that may be and especially in the virtual environment where today's preadolescents have found either a confidant, an emotional support, a satisfactory of needs or even a refuge. This new environment that in the last 15 years has developed amazingly, and which was meant to make our lives easier and bring us only satisfaction, has also proven to bring dissatisfaction in the most unexpected aspects of developing human life. Another reason why I chose this research topic also comes from personal experience during adolescence, at the beginning of this stage getting acquainted with social media and facing different states or changes of perspective now realizing in adulthood as being at that time flawed for my development, I understood that what was created in my mind and later in my behavior was influenced by the new digital environment to which I had adhered without to think that I will expose myself at the same time to such an influential space.

Understanding longitudinal associations between problematic peer relations and psychopathology is needed to inform public health. Three models have been proposed: Poor peer relations (a) lead or are a risk factor for psychopathology, (b) lag or are a consequence of psychopathology, or (c) both lead and lag psychopathology. Another model is that poor peer relations lead or lag psychopathology depending on the developmental period. To test these models, youths’ peer relations and clinical symptoms were assessed up to six times between ages 3 and 11 in 306 children. Bivariate latent-change-score models tested leading and lagging longitudinal relationships between children’s peer relations (peer victimization/rejection, peer-directed aggression, social withdrawal, prosocial behavior) and psychopathology (depression, anxiety, and externalizing symptoms). Peer victimization/rejection was a leading indicator of depression from early childhood into preadolescence. Peer-directed aggression was a leading indicator of externalizing symptoms (in late childhood).

Vaccines that protect against infection with the types of human papillomavirus (HPV) commonly associated with cervical cancer (HPV 16 and 18) and genital warts (HPV 6 and 11) are expected to become available in the near future. Because HPV vaccines are prophylactic, they must be administered prior to exposure to the virus, ideally during preadolescence or adolescence. The young age of the target vaccination population means that physicians, parents, and patients will all be involved in the decision-making process. Research has shown that parents and patients are more likely to accept a vaccine if it is efficacious, safe, reasonably priced, and recommended by a physician. Widespread education of physicians, patients, and parents about the risks and consequences of HPV infection and the benefits of vaccination will be instrumental for fostering vaccine acceptance.

AbstractThis longitudinal study considers externalizing behavior problems from ages 5 to 27 (N= 585). Externalizing problem ratings by mothers, fathers, teachers, peers, and self-report were modeled with growth curves. Risk and protective factors across many different domains and time frames were included as predictors of the trajectories. A major contribution of the study is in demonstrating how heterotypic continuity and changing measures can be handled in modeling changes in externalizing behavior over long developmental periods. On average, externalizing problems decreased from early childhood to preadolescence, increased during adolescence, and decreased from late adolescence to adulthood. There was strong nonlinear continuity in externalizing problems over time. Family process, peer process, stress, and individual characteristics predicted externalizing problems beyond the strong continuity of externalizing problems. The model accounted for 70% of the variability in the development of externalizing problems. The model's predicted values showed moderate sensitivity and specificity in prediction of arrests, illegal drug use, and drunk driving. Overall, the study showed that by using changing, developmentally relevant measures and simultaneously taking into account numerous characteristics of children and their living situations, research can model lengthy spans of development and improve predictions of the development of later, severe externalizing problems.

Most research examining the influences of maternal employment focuses on the mother and the child at only one stage of the child's life. By contrast, this study examines how temporal and status aspects of mothers' jobs during daughters' early childhood (aged 0 to 6), preadolescence (aged 7 to 12), and adolescence (aged 13 to 18) affect a key transition: the rate that daughters leave school. The sample consists of 246 White and 188 Black daughters aged 18 to 23 in 1990, drawing on data from both mothers and daughters from the 1968-1990 waves of the Panel Study of Income Dynamics. Findings suggest that part-time maternal employment during any point in childhood increases the likelihood that Black, but not White, daughters will remain in school. Maternal employment characteristics have little influence in determining whether White daughters remain in school.

Using network analysis, we investigated the relationships between maladaptive psychological functioning, difficulties in emotion regulation, and risk-taking in deliberative and affective behavioral decisions. Participants (103 adolescents aged between 13 and 19 years, 62% boys) took the Cold (deliberative) and Hot (affective) versions of the Columbia Card Task and completed the Youth Self-Report (YSR) and the Difficulties in Emotion Regulation Scale (DERS). In contrast to the view that risk propensity increases from preadolescence to middle adolescence and decreases at later ages, our study revealed no age-specific trend. YSR syndrome scales were significantly correlated with risk propensity, but only in the Cold version. The YSR Thought Problems scale was the most central node in the network, linking internalizing and externalizing problems with risk propensity in the Cold CCT. Lack of emotional Clarity was the only DERS consistently linked with risk-taking both in correlation and network analyses. Maladaptive psychological functioning and difficulties in emotion regulation were linked with risk propensity in affective risky decisions through deliberative processes. The statistical significance of direct and indirect effects was further examined using nonparametric mediation analyses. Our study highlights the role of cognitive factors that in each variable set might account for risk-taking in teenagers.

Background - Several studies have investigated the use of digital media in developmental age, mainly focusing on Internet or video games addiction in adolescence. However, few studies have investigated the time spent by children and young people on different types of digital media and their impact on adaptive behaviour. Objectives - On the base of parent and child reports the current study aimed to investigate the use of different digital media in Italian children and adolescents, aged six to eighteen, and their impact on adaptive behaviour as well, and to assess its association with socio-demographic factors. Material and methods - 901 parents and 574 children were recruited in ten schools in Northern Italy. The parents filled in a socio-demographic form and the “Media Activity Form” (MAF-G), while adolescents filled in a youth version of the “Media Activity Form” (MAF-R). Results - Overall, the activities carried out by children (6-11 years old) are mainly focused on viewing films/TV series and using video games, while those of adolescents are mainly related to listening to music and messaging. Parents estimated a lower amount of time spent on digital media by their children compared to that reported by their children. Finally, significant differences emerged in relation to male gender, preadolescence, low socio-economic level, low maternal education and divorced/separated parents, showing that participants belonging to such categories spent longer time on different digital media. Conclusions - The results contributed to improve the knowledge on the use of digital media in children and adolescents, with useful clinical implications for interventions.

The outcomes of 26 children who had an apparent life-threatening event during sleep and who were monitored at home were evaluated. In a preliminary study that was first reported when the children had a mean age of 2.7 years, only minor behavioral difficulties were seen. The children of this earlier study were characterized by more aggressive behavior, which was tentatively related to parental anxiety. The same children were retested at a mean age of 7 years (range 6 to 10 years), together with sex-, age-, and social class-matched control children. No significant differences were found in their clinical daytime and nighttime behavior or in IQ tests, although in some of the psychodevelopmental tests minor signs of anxiety were revealed. In conclusion, infants with an apparent life-threatening event who underwent continued cardiopulmonary home monitoring develop normally during preadolescence. A prolonged follow-up of the children during adolescence is needed to evaluate later school performance.

Although osteoporosis typically surfaces in later life, peak bone mass attained before age 20 is a key factor in its prevention. However, most American children’s diets lack sufficient calcium during the critical growth periods of preadolescence and adolescence to achieve peak bone mass. Better Bones (BB) Buddies is an educational program targeting children ages 9–15 years in an effort to improve their knowledge of bone health and to increase their intake of calcium-rich foods, thereby reducing the risk for osteoporosis later in life. In the 1998–1999 school year, Better Bones Buddies was given to more than 2,200 school children in southeastern South Dakota and southwestern Minnesota. Posttest results ( N = 900) indicate participants improved in their knowledge of osteoporosis, and half reported modifications in their dietary habits to increase calcium consumption. Implications of the Better Bones Buddies program are discussed, with recommendations for future use of this program to increase children’s knowledge about bone growth and osteoporosis.
