Distributive fairness during the transition to adolescence: The role of peer comparison and social value orientation.

Combining the dictator game (DG) and the ultimatum game (UG), this study recruited 546 Chinese children (321 boys, aged 9-12 years) as distributors, and found that both peer comparison and social value orientation (SVO) significantly influenced children's distributive fairness from late childhood to early adolescence. Results showed that as the unfairness of peer proposals increased, participants decreased the amount of gold coins distributed to the receiver in both tasks, revealing a peer comparison effect. This effect was more pronounced for adolescents than for children in both tasks. In addition, participants' fair distribution behaviors in the DG showed a three-way interaction effect of SVO, grade, and peer comparison. Specifically, for proselfs, children were not influenced by peers and consistently proposed self-interested distributions, whereas adolescents exhibited a peer comparison effect; for prosocials, both children and adolescents were influenced by peers, but children decreased the amount of their distributions only when they saw peers make extremely unfair distributions, whereas adolescents decreased the amount of their distributions when they saw peers make both mildly and extremely unfair distributions. This study highlights the importance of social environment and personal trait in shaping children's fair distribution behavior during the transition from late childhood to early adolescence.

Delay discounting and nucleus accumbens functional connectivity are related to weight status in adolescents from the ABCD study.

Despite the growing epidemic of paediatric obesity, questions remain regarding potential neural mechanisms for individual risk. Delay discounting is a cognitive process of comparison of valuation between immediate and delayed reward, which has been inconsistently linked to weight status. Moreover, central to the brain's reward system is the nucleus accumbens, a region structurally and functionally altered in obesity. This study aimed to examine the relationships between two continuous metrics of weight status, performance on a monetary delay-discounting task and nucleus accumbens functional connectivity in 10-12-year-olds from the Adolescent Brain and Cognitive Development (ABCD) Study. Using multilevel longitudinal linear modelling, we found greater discounting was associated with higher BMI Z-scores (BMIz) and waist-to-height ratio Z-scores (WHtRz) (N = 3819). Moreover, we observed functional connectivity of the nucleus accumbens to the cingulo-opercular, dorsal attention, fronto-parietal, salience and ventral attention networks were predictive of BMIz (N = 1817). Nucleus accumbens functional connectivity was not found to mediate the association between delay-discounting behaviour and BMIz. Delay discounting and nucleus accumbens functional connectivity are independently related to weight status in a large sample of early adolescents. A better understanding of the relationship between reward and overeating behaviours may better inform obesity interventions.

The relationship between insecure attachment and nicotine dependence among users of classic cigarettes, e-cigarettes, and heated tobacco products: a moderated mediation model

BackgroundPrevious research has investigated the association between attachment styles and smoking behaviors, indicating a positive association of insecure attachment styles with nicotine dependence. However, these links were mostly explored in adolescent and student samples. Moreover, the explanatory mechanisms and the variables influencing the strength of this relationship remained understudied. In this context, the present study aims to: (1) examine the associations between attachment anxiety, avoidance, and nicotine dependence; (2) investigate the mediating role of emotion dysregulation and metacognitions about smoking; and (3) test the moderating roles of psychological capital and type of tobacco product used by the participants.MethodThis cross-sectional study was conducted on a convenience sample of 447 participants who reported smoking. The age range of participants was 18 to 64 (M = 26.76; 59.7% women). All participants have completed five questionnaires measuring nicotine dependence, adult attachment, emotion dysregulation, metacognitions about smoking, and psychological capital. They also reported the type of tobacco product commonly used: classic cigarettes, e-cigarettes, or heated tobacco products.ResultsOur findings show that the direct link between insecure attachment and nicotine dependence is rather inconsistent. However, it was mediated by the metacognitions about smoking. Psychological capital can act as a protective factor against the effects of attachment on nicotine dependence, especially for those using alternative tobacco products alongside classic cigarettes.ConclusionsThe findings highlight the possibility of developing better-tailored interventions and treatments to discourage smoking and increase smoking cessation. These should focus on eliminating the dysfunctional beliefs related to the metacognitions about smoking and on improving the levels of psychological capital. In addition, targeting attachment insecurities in early adolescence can also function as a mean to prevent smoking.

The Psychological Impact of Trichotillomania

Trichotillomania is a psychiatric disorder characterized by repetitive hair-pulling, leading to significant distress and hair loss, particularly in females during early adolescence (ages 10-13). Although it is classified under Obsessive-Compulsive and Related Disorders in the DSM-5, there is ongoing debate about this classification due to its unique features. The disorder often co-occurs with other psychiatric conditions, such as depression and anxiety, necessitating comprehensive psychiatric evaluations for accurate diagnosis and treatment. Behavioral therapy, particularly habit reversal therapy (HRT), is the most effective treatment, though its benefits are often temporary, lasting only 3 to 6 months, highlighting the need for sustained management. Additionally, trichotillomania can lead to severe physical complications, such as gastrointestinal obstructions (trichobezoars) in those who ingest pulled hair, making physical health screenings critical. Despite the disorder's impact, many patients do not seek treatment due to shame or the belief that healthcare providers lack sufficient knowledge about the condition, pointing to a significant gap in awareness and the need for better education among professionals. Given the significant psychological and physical impacts of trichotillomania, healthcare providers must prioritize early recognition, comprehensive care, and ongoing management to treat patients effectively.

Gender-Specific Effects of Bullying Victimization on Reactive Aggression Among Chinese Early Adolescents: A Longitudinal Mediating Effect of Depressive Symptoms

ABSTRACT In recent years, bullying victimization has received increasing attention from researchers worldwide. The link between bullying victimization and reactive aggression is well-established in numerous studies. However, longitudinal association and underlying mechanisms remain less explored. This study examined gender-specific effects of traditional and cyberbullying victimization on reactive aggression using longitudinal data from 486 Chinese primary and middle school students (51.44% boys, average age = 11.66 ± 1.66 years). Assessments occurred every six months across three waves. Structural equation modeling and multigroup analyses were used to test mediating effects and gender differences. Depressive symptoms mediated the association between traditional bullying victimization and reactive aggression, but no such mediation was observed for cyberbullying victimization. Gender differences were also found (ΔCFI = 0.03, ΔRESEA = 0.01). These findings underscore the importance of gender-specific interventions and supportive environments for addressing offline and online bullying.

Reliability of self-reported pubertal development scale for girls in early adolescent: a school population-based study.

The study aimed to evaluate the correlation between self-reported pubertal developmental scale (PDS) and physically assessed Tanner staging by an experienced pediatrician among girls. In a school population-based study in Zhongshan, China, we recruited 1,722 girls in grades 1-3 by a multistage stratified cluster random sampling method. Participants completed self-reported PDS questionnaire prior to physical examination. Breast development was evaluated by a female pediatrician combined with ultrasound examination for overweight/obese girls; pubic hair development was evaluated. Otherwise, we tested follicle-stimulating hormone (FSH) and luteinizing hormone (LH) for some participants. We observed a weak association between Tanner-derived composite stage (TDCS) and puberty category scores (PCS) (τ=0.288, p<0.001) among all girls. There was correlation (τ=0.314, p=0.001) between ultrasound-derived composite stage (UDCS) and PCS among overweight/obese girls. Moreover, among overweight/obese girls, PCS was positively correlated with LH (r=0.265, p=0.008), but not FSH (r=0.155, p=0.123), and when the basal LH value was greater than 0.3 mIU/mL, the proportion of PCS stage≥2 (9/18) was higher than the proportion of TDCS≥2 (5/18). As for the determination of pubertal onset, when UDCS was used as the gold standard, the specificity of PCS was 0.86 and positive predictive value was 90.00 %. There was a weak correlation between PCS and TDCS among girls early adolescence. Moreover, among overweight/obese girls, combining hormone values, ultrasonographic stage of breast, and the positive predictive value of PCS, we posit that self-reported PDS might be a more reliable method than TDCS to evaluate pubertal development among overweight/obese girls.

The Developmental Collision Hypothesis: An Empirical Test With Three Generations of Sexual Minority Youth.

Sexual minority youth experience disproportionate rates of mental health symptomatology relative to their heterosexual peers. Less is known about why these disparities have persisted despite growing public awareness of sexual diversity. The developmental collision hypothesis states that increased cultural visibility of sexual diversity has accelerated the developmental timing of sexual minority identity formation processes such that they collide with early adolescence, a uniquely sensitive period for experiencing identity-based stigma and associated mental health vulnerability. To test this hypothesis, levels and relations between ages of sexual minority identity development milestones, frequency of LGBT-related victimization, and depressive symptoms were examined across three age-matched but cohort-distinct samples of sexual minority adolescents. Data come from three secondary datasets of sexual minority youth who were adolescents in the 1990s, 2000s, and 2010s, respectively: the Challenges and Coping Study, the Victimization and Mental Health among High Risk Youths Study, and the Risk and Protective Factors for Suicide among Sexual Minority Youth Study (n = 1312; Mage = 17.34, SD = 1.30; 52% female). Adolescents from more recent cohorts reported earlier mean ages of several milestones but similar frequencies of LGBT-related victimization relative to those from less recent cohorts. Path analysis models showed that earlier milestones were associated indirectly with more depressive symptoms through LGBT-related victimization. Notably, earlier ages of self-identification and disclosure of a sexual minority identity were also directly related to less depressive symptoms. Few generational differences in relations between constructs emerged. Findings garner initial support for the developmental collision hypothesis and suggest that LGBT-related victimization, rather than earlier milestones themselves, increases mental health vulnerability.

Dopamine D1 receptors activation rescues hippocampal synaptic plasticity and cognitive impairments in the MK-801 neonatal schizophrenia model

Schizophrenia is a disorder with a higher cognitive decline in early adulthood, causing impaired retention of episodic memories. However, the physiological and behavioral functions that underlie cognitive deficits with a potential mechanism to ameliorate and improve cognitive performance are unknown. In this study, we used the MK-801 neurodevelopmental schizophrenia-like model. Rats were divided into two groups: one received MK-801, and the other received saline for five consecutive days (7–11 postnatal days, PND). We evaluated synaptic plasticity late-LTP and spatial memory consolidation in early adolescence and young adulthood using extracellular field recordings in acute hippocampal slices and the Barnes maze task. Next, we examined D1 receptor (D1R) activation as a mechanism to ameliorate cognitive impairments. Our results suggest that MK-801 neonatal treatment induces impairment in late-LTP expression and deficits in spatial memory retrieval in early adolescence that is maintained until young adulthood. Furthermore, we found that activation of dopamine D1R ameliorates the impairments and promotes a robust expression of late-LTP and an improved performance in the Barnes maze task, suggesting a novel and potential therapeutic role in treating cognitive impairments in schizophrenia.

B - 65 Adolescent Cortico-Limbic Connectivity Mediates Associations between Internalizing Symptomology and Subsequent Neurocognitive Performance

Abstract Objective During development, internalizing symptoms negatively impact broad neurocognitive functioning. Hypoconnectivity between the Cingulo-Opercular network (CON) and limbic regions has been implicated in various psychiatric disorders. Here we attempt to investigate whether CON-limbic connectivity longitudinally mediates associations between internalizing behaviors and cognitive outcomes during adolescence. Method Internalizing symptoms were measured in 2668 youth (47% female) enrolled in the Adolescent Brain Cognitive Development study using the Child Behavior Checklist. Zero-order correlations were tested between baseline (ages 9–11) internalizing symptoms (anxiety, depression, somatic complaints) and performance on NIH Toolbox® neurocognitive measures at 4-year follow-up (ages 13–15). Significantly predicted tasks were included in a structural equation model (SEM), which tested whether a latent factor representing 2-year follow-up resting-state fMRI connectivity between the CON and limbic regions (i.e., bilateral hippocampus and amygdala) mediated associations between baseline internalizing symptoms and 4-year cognitive outcomes. Results Four neurocognitive tasks (Flanker, Picture Sequence, List Sorting, Pattern Comparison) regressed significantly onto at least one internalizing symptom. An SEM which tested the mediatory effects of CON-limbic connectivity on these associations fit the data well (CFI = 0.997; SRMR = 0.007; RMSEA =0.015 [0,0.027]). Increased anxiety and somatic symptoms significantly predicted reduced CON-limbic connectivity, while depression did not. Associations between anxiety and somatic symptoms and List Sorting performance were suppressed, indicating full mediation by CON-limbic connectivity on working memory. Connectivity also partially mediated a negative association between anxiety and Flanker performance. Conclusions Our findings point to CON-limbic hypoconnectivity as a potential mechanism underlying associations between late childhood internalizing symptoms and poorer executive functioning (most notably working memory) during early adolescence.

Coaching in the ‘alternate universe’ of U.S. Figure skating: a developmental perspective of need-supportive behavior in the coach-athlete relationship

Need-supportive coaching has been identified as the most effective way to nurture optimal motivational climates in sport because of its positive influence on athletes’ basic psychological needs of autonomy, competence, and relatedness. However, to date, researchers in sport have not adequately considered whether athletes’ physical, cognitive, social, self, and emotional development prompts any variation in coaches’ delivery of need-supportive behavior. Such insight may reveal a more nuanced approach for coaches to facilitate athletes’ psychological functioning in an age-appropriate way. Therefore, the purpose of this study was to explore athletes’ and coaches’ perceptions of how coaches consider athlete development in the ways in which they seek to fulfill athletes’ basic psychological needs. Figure skating is an ideal sport context for this investigation as coach-athlete relationships typically span many years and developmental milestones. Semi-structured interviews were conducted with 13 coach-athlete dyads (26 interviews) across four age groups: middle childhood (6–10 years), early adolescence (11–14 years), mid-adolescence (15–17 years), and early adulthood (18–25 years). Using reflexive thematic analysis, seven themes were constructed: (a) sport context as a lens for the optimal skill development of athletes, (b) socio-chronological development and relatedness-associated behavior, (c) physical development and relatedness- and competence-associated behavior, (d) skill and ability development and competence-associated behavior, (e) understanding of the sport and autonomy-associated behavior, (f) emotional development and relatedness-behavior, and (g) relational qualities further shape coaches’ need-supportive behaviors.

Effects of chronic social defeat stress on social behavior and cognitive flexibility for early and late adolescent

This study investigated the risk to social behavior and cognitive flexibility induced by chronic social defeat stress (CSDS) during early and late adolescence (EA and LA). Utilizing the “resident-intruder” stress paradigm, adolescent male Sprague-Dawley rats were exposed to CSDS during either EA (postnatal days 29–38) or LA (postnatal days 39–48) to explore how social defeat at different stages of adolescence affects behavioral and cognitive symptoms commonly associated with psychiatric disorders. After stress exposure, the rats were assessed for anxiety-like behavior in the elevated plus maze, social interaction, and cognitive flexibility through set-shifting and reversal-learning tasks under immediate and delayed reward conditions. The results showed that CSDS during EA, but not LA, led to impaired cognitive flexibility in adulthood, as evidenced by increased perseverative and regressive errors in the set-shifting and reversal-learning tasks, particularly under the delayed reward condition. This suggests that the timing of stress exposure during development has a significant impact on the long-term consequences for behavioral and cognitive function. The findings highlight the vulnerability of the prefrontal cortex, which undergoes critical maturation during early adolescence, to the effects of social stress. Overall, this study demonstrates that the timing of social stressors during adolescence can differentially shape the developmental trajectory of cognitive flexibility, with important implications for understanding the link between childhood/adolescent adversity and the emergence of psychiatric disorders.

Gender Identity Disparities in Early Adolescent Sleep: Findings from the Adolescent Brain Cognitive Development Study.

Purpose: Our aim was to examine associations between transgender identity and sleep disturbance in a demographically diverse, national sample of U.S. early adolescents. Methods: We conducted a cross-sectional analysis of the Adolescent Brain Cognitive Development Study from Year 3 (2019-2021, n = 10,277, 12-13 years) to investigate the association between transgender identity and caregiver-reported measures of their adolescent's sleep, assessed by the Sleep Disturbance Scale for Children. Results: Transgender adolescents had a higher risk of overall sleep disturbance and symptoms of insomnia and excessive sleepiness. Furthermore, per caregiver report, transgender adolescents were more likely to have shorter sleep duration categories; particularly concerning is the significant risk of <5 hours of sleep for transgender adolescents compared with their cisgender peers. Conclusion: These findings indicate that transgender adolescents had worse caregiver-reported sleep outcomes compared to cisgender peers. This study highlights the need for screenings and interventions targeted at improving sleep among transgender adolescents.

Gender Differences in Coolness Dynamics Among Early and Middle Adolescents

The paper investigates gender differences in coolness dynamics among early and middle adolescents in a Hungarian panel dataset, which followed students from grade 5 (age 11–12) to grade 8 (age 14–15). Drawing on Gender Prototypicality Theory, we expected significantly different gendered patterns in the association between coolness and various forms of aggression, academic performance, physical attractiveness, BMI, and two forms of risk behavior (smoking, drinking). However, our multilevel models showed that behaviors traditionally considered masculine tended to be associated with coolness for both sexes, but in particular for girls. Some traditionally masculine behaviors (such as verbal aggression, smoking, or lower GPA) tended to be more strongly or only associated with status among girls. On the other hand, while physical attractiveness was associated with status for both sexes, this association was stronger among boys. Cultural and contextual explanations, as well as policy implications, are also discussed.

When ethnic-racial discrimination from math teachers spills over and predicts the math adjustment of nondiscriminated adolescents: The mediating role of math classroom climate perceptions.

Ethnic-racial discrimination is a pernicious experience that affects discriminated adolescents' healthy human development, but the spillover consequences of discrimination on the nondiscriminated adolescent population are less clear. Adolescents who vicariously witness their classmates experience ethnic-racial discrimination from educators may question their educators' authority and classroom rules, and educators who perpetuate discrimination may engage in other practices that disadvantage the entire classroom. Thus, we posed three research questions: Did classmates' ethnic-racial discrimination from teachers predict adolescents' classroom adjustment outcomes (e.g., class grades, test scores, and engagement), did classroom climate mediate the link between classmates' ethnic-racial discrimination and adolescents' classroom adjustment outcomes, and did the results differ between early versus middle adolescents? To answer these research questions, the present study leveraged longitudinal data among 1,539 adolescents (Mage = 13.81, SDage = 1.49; 60% Black, 30% White, 9% other, 1% Asian; 49% female, 51% male) nested in 104 math classrooms, as math is a subject domain with pervasive ethnic-racial stereotypes about students' abilities and opportunities to succeed in class. Results illustrated that direct and vicarious ethnic-racial discrimination from math educators in the fall semester predicted worse math course grades, state-administered standardized test scores, and classroom engagement across the fall and spring semesters. Math classroom climate perceptions mediated the longitudinal relations between ethnic-racial discrimination and their math adjustment outcomes, and the role of ethnic-racial discrimination varied across different developmental stages of adolescence. Implications for the measurement of ethnic-racial discrimination in the classroom context and the social contagion linked to ethnic-racial disadvantage are discussed.

Screen time, problematic screen use, and eating disorder symptoms among early adolescents: findings from the Adolescent Brain Cognitive Development (ABCD) Study

PurposeEmerging research evidence suggests positive relationships between higher screen time and eating disorders. However, few studies have examined the prospective associations between screen use and eating disorder symptoms in early adolescents and how problematic screen use may contribute to symptom development.MethodsWe analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,246, 2016–2020, ages 9–14). Logistic regression analyses were used to estimate the longitudinal associations between baseline self-reported screen time and eating disorder symptoms in year two. Logistic regression analyses were also used to estimate cross-sectional associations between problematic screen use in year two (either problematic social media or mobile phone use) and eating disorder symptoms in year two. Eating disorder symptoms based on the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) included fear of weight gain, self-worth tied to weight, engaging in compensatory behaviors, binge eating, and distress with binge eating.ResultsEach additional hour of total screen time and social media use was associated with higher odds of fear of weight gain, self-worth tied to weight, compensatory behaviors to prevent weight gain, binge eating, and distress with binge eating two years later (odds ratio [OR] 1.05–1.55). Both problematic social media and mobile phone use were associated with higher odds of all eating disorder symptoms (OR 1.26–1.82).ConclusionsFindings suggest greater total screen time, social media use, and problematic screen use are associated with more eating disorder symptoms in early adolescence. Clinicians should consider assessing for problem screen use and, when high, screen for disordered eating.Level of evidenceLevel III: Evidence obtained from well-designed cohort or case–control analytic studies.

An Exploration of Sexual Consent Beliefs, Attitudes, and Behaviors among Middle School Students in Canada

An essential component of healthy sexual exploration is the understanding of sexual consent. Unfortunately, sexual consent is not consistently taught in sex education programs developed for adolescents. Furthermore, although early adolescence is a critical developmental period for the formation of sexual identity, norms, attitudes, and relationships, this population is underrepresented in the sexual consent literature. To fill this important gap, this study examined the sexual consent beliefs, attitudes, and behaviors of 254 middle school students from a large, urban city in the province of Ontario. Correlates and predictors of sexual consent endorsement were tested via bivariate and multiple regression analyses. Greater perceived negative sanctions of dating violence and higher endorsement of gender stereotypes emerged as variables significantly related to and predictive of sexual consent attitudes, perceived behavioral control, and affirmative consent norms. Gender was also a significant correlate, as girls were more likely than boys to endorse affirmative sexual consent beliefs, attitudes, and behaviors. The findings highlight important group differences and provide guidance for the design and implementation of sexual education and prevention programs.

Update on Antisocial Personality Disorder.

Antisocial personality disorder (ASPD) is a characterized by lifelong or recurrent behavioral problems that begin in childhood or early adolescence. This communication provides an overview on ASPD including findings from recent reviews and new research. With regard to DSM-5's Section III Alternative Model of Personality Disorder criteria for ASPD, advocates point to the broader symptom coverage and harmonization with ICD-11; yet critics point to the lack of evidence for improved outcomes. A new report shows that antisocial individuals age faster than non-antisocial peers. ASPD has high heritability and newer molecular studies have found intriguing linkages to genes associated with crucial brain regions. A mentalization-based therapy model has been developed and early work shows promise. ASPD is common, widespread, and disruptive to individuals, families, and society. Chronic and lifelong, ASPD typically lessens in severity with advancing age. Assessment rests on the individual's history because there are no diagnostic tests. ASPD likely results from an interplay ofgenetic and environmental factors. Brain imaging studies have linked cortical dysfunction to antisocial behavior in crucial brain regions. Medication is sometimes targeted at the individual's aggression and irritability, but a more rational approach is to target co-occurring disorders. Cognitive-behavioral therapy and mentalization-based therapy models have been developed and are being studied.

Developmental Trajectories of Transactional Sex and Age-Disparate Relationships During Adolescence: An HPTN 068 Analysis.

Transactional sex and sexual relationships with older partners increase HIV risk in adolescent girls and young women (AGYW), yet little is known about how these behaviors co-evolve over time. We characterize temporal patterns of transactional sex and age-disparate relationships among AGYW in South Africa. Longitudinal data are from a randomized controlled trial (HPTN 068) of school-aged, HIV-negative, AGYW who attended ≥ 3 study visits. We used group-based trajectory modeling to identify trajectories of transactional sex and age-disparate relationships (partner ≥ 5 years older) in the last year and assessed the interrelationship (conditional probability) between both trajectories. At baseline, median age was 14 years, 14.5% of girls were sexually active, and transactional sex (2.1%) and age-disparate relationships were uncommon (2.7%). We identified two trajectories for transactional sex ("low" [81.9%] and "increasing" [18.1%]) and two for age-disparate relationships ("low" [91.7%] and "increasing" [8.3%]). In a separate joint trajectory analysis, nearly a third (28%) had increasing trajectories for both transactional sex and age-disparate relationships, but most (53%) had a low trajectory of both outcomes. Baseline reporting of early sexual debut, depression, and inequitable gender norms were highest in the increasing transactional sex group. Prior pregnancy, early sexual debut, and IPV were highest among those with increasing age-disparate relationships. AGYW who engage in transactional sex or age-disparate partnerships in early adolescence are more likely to experience sustained engagement in both behaviors as they transition to adulthood, increasing HIV risk. Engaging girls early may maximize effectiveness of behavioral and biomedical HIV prevention efforts.
