Neural Tracking of Perceived Parent, but Not Peer, Norms Is Associated with Longitudinal Changes in Adolescent Attitudes about Externalizing Behaviors.

Adolescents' perceptions of parent and peer norms about externalizing behaviors influence the extent to which they adopt similar attitudes, yet little is known about how the trajectories of perceived parent and peer norms are related to trajectories of personal attitudes across adolescence. Neural development of midline regions implicated in self-other processing may underlie developmental changes in parent and peer influence. Here, we examined whether neural processing of perceived parent and peer norms in midline regions during self-evaluations would be associated with trajectories of personal attitudes about externalizing behaviors. Trajectories of adolescents' perceived parent and peer norms were examined longitudinally with functional neuroimaging (n = 165; ages 11-16 years across three waves; 86 girls, 79 boys; 29.7% White, 21.8% Black, 35.8% Latinx, 12.7% other/multiracial). Behavioral results showed perceived parent norms were less permissive than adolescents' own attitudes about externalizing behaviors, whereas perceived peer norms were more permissive than adolescents' own attitudes, effects that increased from early to middle adolescence. Although younger adolescents reported less permissive attitudes when they spontaneously tracked perceived parent norms in the ventromedial and medial pFCs during self-evaluations, this effect weakened as they aged. No brain-behavior effects were found when tracking perceived peer norms. These findings elucidate how perceived parent and peer norms change in parallel with personal attitudes about externalizing behaviors from early to middle adolescence and underscore the importance of spontaneous neural tracking of perceived parent norms during self-evaluations for buffering permissive personal attitudes, particularly in early adolescence.

Sex gaps and age differences in the structure of academic cyberloafing from early to middle adolescence: A network analysis.

Academic cyberloafing refers to students' engagement in non-learning-related online activities during online courses, which can negatively affect their academic performance. Prior studies investigated cyberloafing primarily in the workplace, neglecting core behaviors and interactions among academic cyberloafing in educational contexts. This study employed network analysis to capture academic cyberloafing as an interactive behavior network to explore the core behavioral patterns of academic cyberloafing and the interactions between these behaviors. A total of 3537 adolescents (Mage = 12.49; 53.7% boys and 46.3% girls) in China were included in this study. The findings indicated that "seeking gossip news" and "watching short videos" are central behaviors. Among boys, "browsing nonacademic web pages" and "watching short videos" are central behaviors; "seeking gossip news" is the most central behavior among girls. Furthermore, in early adolescence, central behaviors encompass "chatting privately" and "seeking gossip news"; in middle adolescence, central behaviors include "seeking gossip news" and "watching short videos."Additionally, the comparisons indicated that academic cyberloafing networks (between boys and girls; between early and middle adolescence) show a similar structure and global strength but differ in specific academic cyberloafing associations. As adolescents of different sexes and ages engage in academic cyberloafing differently, tailored education interventions can be implemented to address unregulated cyberloafing.

Influence of chronotype on pain incidence during early adolescence.

During adolescence major shifts in sleep and circadian systems occur with a notable circadian phase delay. Yet, the circadian influence on pain during early adolescence is largely unknown. Using 2 years of data from the Adolescent Brain Cognitive Development study, we investigated the impact of chronotype on pain incidence, moderate-to-severe pain, and multiregion pain 1 year later in U.S. adolescents. Based on the Munich ChronoType Questionnaire, chronotype was calculated as the midpoint between sleep onset and offset on free days, corrected for sleep debt over the week. Adolescents reported pain presence over the past month, and if present, rated pain intensity (0-10 numerical rating scale; ≥ 4 defined as moderate-to-severe pain) and body site locations (Collaborative Health Outcomes Information Registry Body Map; ≥2 regions defined as multiregion pain). Three-level random intercept logistic regression models were specified for each pain outcome, adjusting for baseline sociodemographic and developmental characteristics. Among 5991 initially pain-free adolescents (mean age 12.0 years, SD 0.7), the mean chronotype was 3:59 am (SD 97 minutes), and the 1-year incidence of pain, moderate-to-severe pain, and multiregion pain was 24.4%, 15.2%, and 13.5%, respectively. Each hour later chronotype at baseline was associated with higher odds of developing any pain (odds ratio [OR] = 1.06, 95% confidence interval [CI] = 1.01, 1.11), moderate-to-severe pain (OR = 1.10, 95% CI = 1.05-1.17), and multiregion pain (OR = 1.08, 95% CI = 1.02-1.14) during 1-year follow-up. In this diverse U.S. adolescent sample, later chronotype predicted higher incidence of new-onset pain.

Bisphenol AF exposure synergistically increases the risk for suicidality among early adolescents with child maltreatment: A prospective cohort study

BackgroundChild maltreatment (CM) is correlated with suicidality risk among adolescents. Additionally, exposure to bisphenol AF (BPAF) may increase this risk. However, the combined effect of CM and BPAF exposure remains unknown and should be further investigated. MethodsIn this study, 1,475 early adolescents (mean age = 12.48 years) from the Chinese Early Adolescents Cohort were enrolled. Data were collected at three time points with an interval of 12 months between 2019 and 2021. Participants’ history of CM and suicidality (including suicidal ideation and suicidal attempts) were evaluated using a self-report questionnaire. Blood samples were obtained from participants to measure serum BPAF concentrations at baseline. Group-based trajectory modeling was employed to identify different developmental trajectories of suicidality across the three waves. After adjusting for potential confounders, the association between CM and BPAF exposure on suicidal ideation and suicidal attempts was assessed using logistic regression and Poisson regression analyses. ResultsParticipants with CM were associated with a risk of one- and two-year incident suicidality (all ps < 0.05), and BPAF levels were positively associated with two-year incident suicidal ideation (adjusted OR = 1.68, 95% CI: 1.13–2.50). Additionally, middle and high levels of BPAF exposure synergistically increase the risk for one- and two-year incident suicidal ideation among participants with CM (adjusted ORs = 2.00–3.83). Similarly, participants exposed to high-level BPAF as well as CM were at a greater risk of one- and two-year incident suicidal attempts than those with low-level BPAF exposure and no CM (adjusted incidence rate ratio [IRRs] = 2.82–4.34). Moreover, compared with participants with a low developmental trajectory of suicidality across the three waves, high BPAF exposure exhibited a significant synergistic effect on participants with CM in the persistently high suicidal ideation trajectory and the increasing suicidal attempts trajectory (all ps < 0.05). Sex subgroup analysis revealed that females were more susceptible to the synergistic effect of BPAF and CM exposure on suicidality than males. ConclusionsEnvironmental factors and the psychological status of individuals may synergistically increase their susceptibility to suicidality. These results offer novel insights into enhancing our understanding of suicidality among adolescents.

What Happens to Youth Baseball Players Diagnosed With Little League Shoulder and Little League Elbow Syndrome?

The long-term prognosis of baseball and softball players diagnosed with Little League elbow (LLE) and Little League shoulder (LLS) is unknown. Many of these athletes are potentially at risk of developing future shoulder and elbow injuries that may require surgical intervention. This study's purpose is to retrospectively assess 5-year patient-reported outcomes and career progression of a series of youth baseball and softball players diagnosed with LLE and LLS. This institutional review board-approved, single-center, retrospective study evaluated 5-year outcomes of a cohort of youth baseball and softball players diagnosed with LLE and LLS between 2013 and 2017. Demographic and clinical data was recorded including age, gender, primary position, and months played per year. A standardized phone survey was obtained approximately 5 years post-treatment to assess upper extremity function, career progression, and pain recurrence. Sixty-one patients (44 LLE, 17 LLS) met the inclusion criteria and participated in a standardized phone survey. The mean age at the time of diagnosis was 13.2 years and all but one of the athletes were male. On average, about 80% (34/44 LLE, 15/17 LLS) played baseball 9 months or more per year. After diagnosis and nonoperative management, more than 80% (37/44 LLE, 14/17 LLS) were able to return to competition, but up to 40% of players changed positions (9/44 LLE, 7/17 LLS). Five years later, less than half (21/44 LLE, 8/17 LLS) were playing baseball actively. The recurrence rate was >20% (9/42 LLE, 6/17 LLS) with a mean time of recurrence of 8.8 months. Patients who experienced symptom recurrence were less likely to play baseball 5 years later and had lower patient-reported outcomes. A diagnosis of LLE and LLS in early adolescence can be a setback for a young athlete. Fortunately, most athletes will be able to return to competition with ∼50% still competing at 5 years. Very few will progress to future arm surgery, but recurrence rates are relatively high, and these athletes are less likely to participate in their sport 5 years later. Level IV-Retrospective cohort study.

Popularity in Chinese Early Adolescents: A Focus Group Analysis

Popularity is of great developmental significance to early adolescents for its implications on behavioral and adjustment outcomes. Although extensive research on popularity has been conducted in Western cultures, little is known about Chinese adolescents’ indigenous understanding of popularity. The current study examined Chinese early adolescents’ understanding of popularity using focus group interviews to explore the characteristics of popularity and unpopularity, as well as popularity determinants for boys and girls. We conducted interviews on six focus groups comprising 37 Chinese fifth and sixth graders (18 boys, 19 girls). Transcriptions were coded and analyzed through developing coding schemes that included emerged codes and categories. The results showed both cross-cultural similarities and culturally specific findings in adolescents’ perceptions of popularity characteristics and determinants. Specifically, sociability, academic performance, and prosocial behaviors served as major characteristics of popularity, whereas aggressive and disruptive behaviors were regarded as typical attributes of unpopularity. More importantly, culturally unique aspects of popularity characteristics were reported by Chinese adolescents, such as a strong sense of collective honor. When responding what would make a peer popular, Chinese early adolescents reported various behavioral, social, and cultural factors. Findings of this study underscore the importance of examining perceptions of popularity in consideration of the cultural context.

Neural correlates of obesity across the lifespan

Associations between brain and obesity are bidirectional: changes in brain structure and function underpin over-eating, while chronic adiposity leads to brain atrophy. Investigating brain-obesity interactions across the lifespan can help better understand these relationships. This study explores the interaction between obesity and cortical morphometry in children, young adults, adults, and older adults. We also investigate the genetic, neurochemical, and cognitive correlates of the brain-obesity associations. Our findings reveal a pattern of lower cortical thickness in fronto-temporal brain regions associated with obesity across all age cohorts and varying age-dependent patterns in the remaining brain regions. In adults and older adults, obesity correlates with neurochemical changes and expression of inflammatory and mitochondrial genes. In children and older adults, adiposity is associated with modifications in brain regions involved in emotional and attentional processes. Thus, obesity might originate from cognitive changes during early adolescence, leading to neurodegeneration in later life through mitochondrial and inflammatory mechanisms.

Predicting higher child BMI z-score and obesity incidence in Malaysia: a longitudinal analysis of a dynamic cohort study.

To target public health obesity prevention, we need to predict who might become obese i.e. predictors of increasing Body Mass Index (BMI) or obesity incidence. Predictors of incidence may be distinct from more well-studied predictors of prevalence, therefore we explored parent, child and sociodemographic predictors of child/adolescent BMI z-score and obesity incidence over 5 years in Malaysia. The South East Asia Community Observatory in Segamat, Malaysia, provided longitudinal data on children and their parents (n = 1767). Children were aged 6-14 years at baseline (2013-14) and followed up 5 years later. Linear multilevel models estimated associations with child BMI z-score at follow-up, adjusting for baseline BMI z-score and potential confounders. Predictors included parent cardiometabolic health (overweight/obesity, central obesity, hypertension, hyperglycaemia), and socio-demographics (ethnicity, employment, education). Logistic multilevel models explored predictors of obesity incidence. Higher baseline BMI z-score predicted higher follow-up BMI z-score both in childhood to late adolescence (0.60; 95% CI: 0.55, 0.65) and early to late adolescence (0.76; 95% CI: 0.70, 0.82). There was inconsistent evidence of association between child BMI z-score at follow-up with parent cardiometabolic risk factors independent of baseline child BMI z-score. For example, maternal obesity, but not overweight, predicted a higher BMI z-score in childhood to early adolescence (overweight: 0.16; 95% CI: -0.03, 0.36, obesity: 0.41; 95% CI: 0.20, 0.61), and paternal overweight, but not obesity, predicted a higher BMI z-score in early to late adolescence (overweight: 0.22; 95% CI: 0.01, 0.43, obesity: 0.16; 95% CI: -0.10, 0.41). Parental obesity consistently predicted five-year obesity incidence in early to late adolescence, but not childhood to early adolescence. An adolescent without obesity at baseline with parents with obesity, had 3-4 times greater odds of developing obesity during follow-up (incidence OR = 3.38 (95% CI: 1.14-9.98, mother) and OR = 4.37 (95% CI 1.34-14.27, father) respectively). Having a higher BMI z-score at baseline was a stronger predictor of a higher BMI z-score at follow-up than any parental or sociodemographic factor. Targeting prevention efforts based on parent or sociodemographic factors is unwarranted but early childhood remains a key period for universal obesity prevention.

The invisible problem of early adolescent pregnancy in the Dominican Republic: a descriptive analysis

Study objectivesThe aim of this article is to describe the problem of pregnancy in girls under 15 years of age in the Dominican Republic in the period 2000–2021, to develop a specific indicator for this age group and describing the related factors. MethodsThis is an exploratory ecological study, based on secondary data sources, such as birth records from the National Statistics Office (NSO) and the Ministry of Public Health (MPH). We calculated the rates of fertility and pregnancy in early adolescence, as well as analyzed their main determining factors and consequences. ResultsFertility Rate in Early Adolescence (FREA) decreases from 6.27 to 1.04 per thousand in the period 2001–2021. The average FREA for 2015–2021 was 1.78. The average Estimated Rate of Pregnancy in Early Adolescence (ERPEA) for the same period was 3.39. Disability-Adjusted Life Years (DALYs) were 11,620 years. Years of Life Lost (YLL) were 9,665.9 years. The prevalence of Low Birth Weight (LBW) in the under 15-year-old age group was 14.2 %. ConclusionsPregnancy in childhood implies risks for both the mother and the child, including low birth weight. The official fertility rate is substantially underreported (2.84 vs. 1.79).The fertility rate indicator traditionally used does not accurately measure the number of pregnancies in women, particularly in specific age groups or populations where pregnancies may be interrupted by various factors. Therefore, the use of ERPEA is recommended.We emphasize the need for implementing the proposed indicator for the target group, as well as monitoring Sustainable Development Goal indicator 3.7.2.

Exploring upbringing styles of highly resilient students in South Africa: A mixed methods study

Parents play a critical role in supporting the development of resilience in childhood and early adolescence. Research into and commitment to resilience is of great importance, as most South Africans lack basic resources. This study investigated the styles of parenting experienced by highly resilient South African students. Participants were 136 South African university students aged 18 to 23 (female = 44.9%, black = 66.9%). They completed the Child and Youth Resilience Measure. Further, six of the highest scoring students participated in in-depth semi-structured interviews on their retrospective parenting experiences. Quantitative analysis showed females had a higher mean resilience score than males. Qualitatively, framework thematic analysis identified the following parenting styles: loving caregiving, and behavioural control. Loving caregiving was expressed through accounts of encouragement, acceptance, and attentive regard. Behavioural control was demonstrated by verbal interactions of discipline, corporal punishment, and curfews. This implies a connection between specific parenting practices and high resilience in students, providing valuable insights for developing programs to boost children's resilience.

Longitudinal Change in Appearance-Related Social Media Consciousness and Depressive Symptoms: A Within-Person Analysis during Early-to-Middle Adolescence.

Online appearance preoccupation may put adolescents at risk of developing mental health challenges, perhaps especially during early-to-middle adolescence. A random intercept cross-lagged panel model assessed within-person associations between appearance-related social media consciousness and depressive symptoms over three time-points with three months between waves. The sample (n = 1594) included U.S. adolescents aged 11-15 (Mage = 13; 47% girls, 46% boys, 7% another gender; 37% Latine, 33% White, 18% Black, 7% Asian). Within-person increases in appearance-related social media consciousness were associated with subsequent increases in depressive symptoms, but not vice versa. There was no evidence of gender differences and results were robust to controlling for both time on social media and offline self-objectification. Thus, online appearance concerns precede mental health challenges during early and middle adolescence.

The mediating role of positive body image between friendship qualities, well-being strategies and identity development among adolescents

AbstractThis study aimed to explore the mediating role of body image in the association between The utilization of strategies aimed at enhancing subjective well-being, friendship qualities, and identity development. The participants consisted of 270 early adolescents, comprising 157 girls (58.15%) and 113 boys (41.85%). Data were collected using several scales, including the “Body Appreciation Scale,” “Subjective Well-Being Increasing Strategies Scale for Adolescents,” “Friendship Qualities Scale,” and “The Dimensions of Identity Development Scale.” Two-stage structural equation modeling was employed to analyze the gathered data. The findings indicated a positive model of identity development in adolescents, highlighting that subjective well-being increasing strategies contribute positively to identity development, and this relationship is mediated by positive body image. Furthermore, the study found that positive body image also mediates the association between adolescents’ identity development and the establishment of quality friendships.

Social epidemiology of online dating in U.S. early adolescents.

To investigate the prevalence and sociodemographic associations of online dating in a demographically diverse U.S. national cohort of early adolescents. We analyzed cross-sectional data from the Adolescent Brain Cognitive Development Study (Year 2, 2018-2020, ages 11-12; N = 10,157). Multivariable logistic regression analyses were employed to estimate associations between sociodemographic factors (e.g., age, sex, race/ethnicity, sexual orientation, household income, parental education) and early adolescent-reported online dating behaviors. Overall, 0.4% (n = 38) of participants reported ever using a dating app. Males (AOR 2.72, 95% CI 1.11-6.78) had higher odds of online dating compared to females, and sexual minority identification (e.g., lesbian, gay, or bisexual; AOR 12.97, 95% CI 4.32-38.96) was associated with greater odds of online dating compared to heterosexual identification. Given the occurrence of online dating among early adolescents despite age restrictions, interventions might address age misrepresentation. Adolescent sexual health education may consider incorporating anticipatory guidance on online dating, especially for males and sexual minorities. Future research could further investigate online dating patterns from early to late adolescence and associated health effects.

Five-year follow-up of the iBerry Study: screening in early adolescence to identify those at risk of psychopathology in emerging adulthood.

The iBerry Study, a Dutch population-based high-risk cohort (n = 1022) examines the transition from subclinical symptoms to psychiatric disorders in adolescents. Here, we present the first follow-up measurement, approximately 3years after baseline assessment and 5years after the screening based on self-reported emotional and behavioral problems (SDQ-Y). We give an update on the data collection, details on the (non)response, and the results on psychopathology outcomes. The first follow-up (2019-2022) had a response rate of 79% (n = 807). Our results at baseline (mean age 15.0years) have shown the effectiveness of using the SDQ-Y to select a cohort oversampled for the risk of psychopathology. At first follow-up (mean age 18.1years), the previously administered SDQ-Y remains predictive for selecting adolescents at risk. At follow-up, 47% of the high-risk adolescents showed significant mental health problems based on self- and parent reports and 46% of the high-risk adolescents met the criteria for multiple DSM-5 diagnoses.Compared to low-risk adolescents, high-risk adolescents had a sevenfold higher odds of significant emotional and behavioral problems at follow-up. Comprehensive assessment on psychopathology, substance abuse, psychotic symptoms, suicidality, nonsuicidal self-injury, addiction to social media and/or video gaming, and delinquency, as well as social development, and the utilization of healthcare and social services were conducted. This wave, as well as the ones to follow, track these adolescents into their young adulthood to identify risk factors, elucidate causal mechanisms, and discern pathways leading to both common and severe mental disorders. Results from the iBerry Study will provide leads for preventive interventions.

Over-the-Counter Medications Encountered in the Postmortem Pediatric Population from 2010-2020.

In forensic toxicology, the pediatric population requires special focus when evaluating positive findings because of the many toxicokinetic and toxicodynamic differences (e.g., metabolic capabilities, body size, etc.) between the pediatric and adult populations. In particular, the administration of over-the-counter (OTC) medications needs careful consideration, as dosages given to the pediatric population (0 days - 18 years), particularly those given to individuals less than five years of age, tend to be lower than those given to individuals closer to adulthood. Postmortem pediatric data from eleven years (2010-2020) was compiled. A total of 1413 positive cases contained one or more of the following common OTC medications: antihistamines (brompheniramine, chlorpheniramine, diphenhydramine, doxylamine, and pheniramine), pain relievers (acetaminophen, naproxen, ibuprofen, and salicylates), cold/flu medications (dextro/levomethorphan, guaifenesin, ephedrine, and pseudoephedrine), gastrointestinal (GI) aids (dicyclomine and loperamide), and/or sleep aids (melatonin). Antihistamines, cold/flu medications, and pain relievers are the most common classes of drugs encountered in the postmortem pediatric population. To evaluate trends, three main age groups were created: ≤5 years old (5U, birth-5 years old), middle childhood (MC, 6-11 years old), and early adolescence (EA, 12-18 years old). When considering the data, it must be noted that many of these drugs may be co-administered in single and/or multi-drug formulations. In addition, some drugs may have a variety of uses, e.g., antihistamines may also be used as sleep aids. Of note, the prevalence of cases involving those aged 6-11 years old was far less than their younger and older pediatric counterparts. With the widespread availability of OTC medications, unintentional overdoses, recreational misuse, and suicidal overdoses can occur in the vulnerable, pediatric population.

Thriving Through Autonomy: High-Ability Adolescents’ Well-Being Amidst the Pandemic

Most research has so far focused primarily on the negative effects of the COVID-19 pandemic on early adolescents. This pre-registered study fills this gap by investigating possible links between pandemic regulations and positive outcomes, namely school well-being. Specifically, we test the assumption that high-ability early adolescents benefit from virtual schooling by experiencing higher school well-being while schooled virtually. Data from a Czech sample ( N = 210) do not support this claim but show a strong effect of autonomy on school well-being. We also explore the changes reported by our participants after returning to classrooms.

Associations between child marriage and reproductive and maternal health outcomes among young married women in Liberia and Sierra Leone: A cross-sectional study.

Child marriage has been associated with a range of negative maternal and reproductive health outcomes. This study explored these associations in Liberia and Sierra Leone and examined how child marriage intersected with other measures of social disadvantage. Data were derived from 631 and 1,325 married or cohabitating women aged 20-24 interviewed in the 2019-2020 Liberia and 2019 Sierra Leone Demographic and Health Surveys, respectively. Analyses were stratified by country. Regression models examined associations between age at first marriage (<15, 15-17, and 18+ years) and reproductive and maternal health outcomes, as well as interactions between child marriage and measures of social disadvantage. Multivariable regression results were presented as adjusted odds ratios and 95% confidence intervals. Over half of currently married/cohabitating women aged 20-24 in Liberia (52%) and Sierra Leone (54%) married before age 18, and over one in 10 married before age 15. In both countries, after adjusting for other factors, being married before the age of 18 was significantly associated with early fertility, high fertility, and low fertility control. Associations were particularly strong among women who first married before age 15. In Liberia, women who married at age 15-17 had significantly lower odds of skilled attendance at delivery and institutional delivery if they lived in the North Central region. Sierra Leonean women who married before age 15 had lower odds of institutional delivery and lower odds of four or more ANC visits if they lived in the North Western region. This study found clear associations between child marriage and negative reproductive health outcomes in Liberia and Sierra Leone, with stronger associations among women married in early adolescence. Child marriage and region of residence intersected to shape young women's access to skilled attendance at birth and institutional delivery. These findings call for further investigation and targeted intervention.

Childhood Trajectories of Paternal and Maternal Psychological Distress and Decision-making in Early Adolescence

AbstractDecision-making is important for adolescent wellbeing, and predictive of several other outcomes. While past research demonstrates the role of maternal psychological distress in adolescent decision-making, the role of paternal psychological distress remains relatively unexplored. This study examined the association between trajectories of paternal and maternal psychological distress, jointly modelled, in childhood and child decision-making in early adolescence. Using data from 9846 families of the Millennium Cohort Study, we identified paternal and maternal psychological distress trajectories across child ages 3–11 using joint group-based trajectory modelling and explored their associations with offspring decision-making at age 11 with multiple linear regression models. Paternal and maternal psychological distress was measured with the Kessler-6 scale, while adolescent decision-making was assessed using the Cambridge Gambling Task. We identified 2 trajectories for fathers (‘low distress’ and ‘moderate-increasing distress’) and 4 for mothers (‘minimal distress’, ‘low distress’, ‘moderate-increasing distress’ and ‘severe distress’). When jointly modelled, paternal and maternal trajectories predicted decision-making in fully adjusted models. Compared to the ‘low distress’ paternal trajectory, the ‘moderate-increasing distress’ paternal trajectory was associated with less delay aversion, although this effect disappeared when examining only two-parent biological families. Compared to the ‘minimal distress’ maternal trajectory, the ‘moderate-increasing distress’ trajectory predicted slower deliberation time, whereas the ‘severe distress’ trajectory predicted greater risk-taking. There were no gender differences in these paths. Consistently moderate and high levels of maternal distress during childhood are associated with increased decision latency and greater risk-taking, respectively, in early adolescence.

Perceived quality of peer relationships and position in peer network from late childhood to early adolescence: A three-wave longitudinal study with cross-lagged panel model

Objective: The main aim of this study was to investigate the mutual relationship between perceptions of peer relationship quality and position in positive and negative peer networks among young people from late childhood to early adolescence. Method: A cross-lagged panel model of three waves of data was conducted using a large representative sample of Polish students from third grade to sixth grade ( N = 4 673). Results: The results proved a reciprocal relationship between position in positive (Like) and negative (DisLike) peer networks and the perceived quality of peer relationships (PPI). The effect found of position on the perceived quality of peer relationships is in line with the existing state of knowledge. Since previous research has yielded divergent results, this demonstration of the prospective impact of perceived relationship quality on peer network position fills an important cognitive gap. The study also revealed the following: (1) in the first (W1→W2) and second period (W2→W3) the strength of the prospective effects of position in the peer network on its perceived quality (Like→PPI and DisLike→PPI), and the strength of the prospective effects of perceived quality on position (PPI→Like and PPI→DisLike), were not statistically significantly different; (2) the effect size of the cross-lagged coefficients ranged from small to medium; (3) all constructs showed greater stability in the second period than in the first; (4) in both periods stability of PPI was lower than the stability of sociometric indicators. Conclusion: This research confirms the presence of a self-reinforcing loop: a low position in peer networks→poor perceived quality of relations→decrease of position in peer networks. The findings are discussed in relation to the evolutionary theory of loneliness (ETL), which assumes a potentially active role of the perception of peer relationships in forming a position in a peer network. Practical implications of the results are discussed.
