A photoaging smartphone application to promote sun safety behaviors among youth in late childhood and adolescence.

Ultraviolet (UV)-exposure behaviors can directly impact an individual's skin cancer risk, with many habits formed during childhood and adolescence. We explored the utility of a photoaging smartphone application to motivate youth to improve sun safety practices. Participants completed a preintervention survey to gather baseline sun safety perceptions and behaviors. Participants then used a photoaging mobile application to view the projected effects of chronic UV exposure on participants' self-face image over time, followed by a postintervention survey to assess motivation to engage in future sun safety practices. The study sample included 87 participants (median [interquartile (IQR)] age, 14 [11-16] years). Most participants were White (50.6%) and reported skin type that burns a little and tans easily (42.5%). Preintervention sun exposure behaviors among participants revealed that 33 (37.9%) mostly or always used sunscreen on a sunny day, 48 (55.2%) experienced at least one sunburn over the past year, 26 (30.6%) engaged in outdoor sunbathing at least once during the past year, and zero (0%) used indoor tanning beds. Non-skin of color (18 [41.9%], p = .02) and older (24 [41.4%], p = .007) participants more often agreed they felt better with a tan. Most participants agreed the intervention increased their motivation to practice sun-protective behaviors (wear sunscreen, 74 [85.1%]; wear hats, 64 [74.4%]; avoid indoor tanning, 73 [83.9%]; avoid outdoor tanning, 68 [79%]). The findings of this cross-sectional study suggest that a photoaging smartphone application may serve as a useful tool to promote sun safety behaviors from a young age.

Adolescent Athletes with Stronger Athletic Identity Perceptions Have Weaker Fear Avoidance Perceptions During Musculoskeletal Injury Rehabilitation Return to Sports Preparation.

Adolescent athletes who sustain a musculoskeletal sports injury are at high re-injury risk. This prospective study evaluated athletic identity perception and fear avoidance perception relationships during the return to sport preparation phase of musculoskeletal injury rehabilitation. From 140 consecutive physical therapy outpatients, 50 (26 females, 24 males) adolescent athletes (mean age 16.8, range 14 to 22 y) completed the 7-item Athletic Identity Measurement Scale (AIMS), the 10-item Athletic Fear Avoidance Questionnaire (AFAQ), and the AFAQ with 2 additional movement-related fear and pain questions (AFAQ+). Correlational analysis was performed of overall AIMS and AIMS subscale scores (social identity, exclusivity, negative affectivity), with AFAQ and AFAQ+ scores (P≤0.05). Adolescent athletes were receiving treatment for musculoskeletal injuries sustained during soccer (n=10), lacrosse (n=7), baseball (n=6), basketball (n=5), volleyball (n=5), track or cross country (n=4), American football (n=4), field hockey or ice hockey (n=3), softball (n=2), tennis (n=2), and gymnastics (n=2). Lower extremity conditions included anterior cruciate ligament reconstruction (n=23) or other lower extremity conditions (n=17). Upper extremity conditions included shoulder dislocation or labral repair (n=6), elbow sprain or fracture (n=3), and clavicle fracture (n=1). The AIMS score displayed moderate inverse relationships with AFAQ (r=-0.40, P=0.008) and AFAQ+ (r=-0.41, P<0.004) scores. The "social identity" AIMS subscale score displayed a moderate inverse relationship with AFAQ (r=- 0.48, P<0.001) and AFAQ+ (r=-0.46, P=0.001) scores. The "exclusivity" AIMS subscale score displayed moderate inverse relationships with AFAQ (r=-0.40, P=0.005) and AFAQ+ (r=-0.46, P=0.001) scores. The "negative affectivity" subscale did not display significant relationships with AFAQ or AFAQ+ scores. Subject age displayed moderate inverse relationships with the AIMS "social identity" (r=-0.56, P<0.001) and "exclusivity" (r=-0.42, P=0.004) subscale scores and weak direct relationships with AFAQ (r=0.30, P=0.04) and AFAQ+ (r=0.32, P=0.02) scores. Adolescent athletes with stronger athletic identity perceptions during the return to the sports preparation phase of musculoskeletal injury rehabilitation had weaker fear avoidance perceptions. As age increased from early to late adolescence, athletic identity perceptions became weaker, and fear avoidance perceptions became stronger. To decrease re-injury rates, early identification and surveillance of injured adolescent athletes with stronger, more exclusive athletic identity perceptions and weaker fear avoidance perceptions may influence rehabilitation progression and return to play decisions.

Sex-dependent effects of acute stress in adolescence or adulthood on appetitive motivation.

Intensely stressful experiences can lead to long-lasting changes in appetitive and aversive behaviors. In humans, post-traumatic stress disorder increases the risk of comorbid appetitive disorders including addiction and obesity. We have previously shown that an acute stressful experience in adult male rats suppresses motivation for natural reward. We examine the impact of sex and age on the effects of intense stress on action-based (instrumental) and stimulus-based (Pavlovian) motivation for natural reward (food). Rats received 15 unsignaled footshocks (stress) in a single session followed by appetitive training and testing in a distinct context. In Experiment 1, stress occurred in either adolescence (PN28) or adulthood (PN70) with appetitive training and testing beginning on PN71 for all rats. In Experiment 2, stress and appetitive training/testing occurred in adolescence. Acute stress in adolescent females suppressed instrumental motivation assessed with progressive ratio testing when testing occurred in late adolescence or in adulthood, whereas in males stress in adolescence did not suppress instrumental motivation. Acute stress in adulthood did not alter instrumental motivation. In contrast, Pavlovian motivation assessed with single-outcome Pavlovian-to-instrumental transfer (SO-PIT) was consistently enhanced in females following adolescent or adult stress. In males, however, stress in adolescence had no effect, whereas stress in adulthood attenuated SO-PIT. Acute stress in adolescence or adulthood altered instrumental motivation and stimulus-triggered Pavlovian motivation in a sex and developmentally specific manner. These findings suggest that the persistent effects of acute stress on Pavlovian and instrumental motivational processes differ in females and males, and that males may be less vulnerable to the deleterious effects of intense stress during adolescence on appetitive motivation.

Profiles of Career Indecision: A Person-Centered Approach with Italian Late Adolescents

Choosing career paths in today’s contemporary labor market complexity is becoming more and more challenging for adolescents and young people. Career indecision could take over, and assessing its facets could guide career interventions to support the career decision-making process. To create increasingly tailored career guidance interventions, using a person-centered approach, this study aimed to understand whether profiles of late adolescents based on their career decision-making difficulties might be circumscribed. A total of 776 Italian late adolescents took part in this study. The assessment of career decision-making difficulties was conducted through the Career Decision-Making Questionnaire (CDDQ). To determine the optimal number of profiles, a Latent Profile Analysis (LPA) using the stepwise approach was used. Moreover, a multinomial logistic regression was conducted to study whether school grade and sex predicted profile membership. LPA revealed a four-profile model: “Lower Indecision” (Profile 1, 39%), “High Indecision” (Profile 2, 23%), “Very High Indecision” (Profile 3, 7%) and “Moderate Indecision” (Profile 4, 31%). Being enrolled in the last year of high school significantly predicted belonging to Profile 2 and Profile 3. Practical implications were discussed in light of these findings.

US Immigration Policy Stressors and Latinx Youth Mental Health

The youth mental health crisis is exacerbated for Latinx adolescents, a group whose families are targets of anti-immigrant rhetoric and policy. To investigate how immigration-related stressors are associated with disruptions in parent-child relationships and, in turn, the mental health symptoms of Latinx adolescents. Data for this prospective cohort study of adolescent-mother dyads were derived from surveys completed at 3 time points spanning 4 years (time 1 [T1] in 2018, time 2 [T2] in 2020, and time 3 [T3] in 2022). Mediation analyses estimated paths from immigration-related stressors to parent-child relationship qualities to mental health symptoms from early to late adolescence. Multivariable and multivariate linear models within a structural equation modeling framework regressed mediators and outcome variables on their own T1 values, offering a scientifically rigorous test of mediation. The setting was a school district in suburban Atlanta, Georgia, and included Latinx adolescents (ages 11-16 years) randomly selected from grade and gender strata. Data were analyzed from June 2023 to March 2024. The primary independent variables were T1 mother reports of anti-immigrant worry and behavioral modification and adolescent reports of family member detention or deportation. Mediating variables were the reports of parental support and parent-child conflict of T2 adolescents. T3 adolescent reports of past 6-month internalizing and externalizing symptoms. A total of 547 Latinx adolescents (mean [SD] age, 13.3 [1.0] years; 303 female [55.4%]; 244 male [44.6%]) were included in this study. Response rates were 65.2% (547 of 839) among contacted parents and 95.3% (547 of 574) among contacted adolescents with parental permission. Four-year retention rates were 67% (366 of 547 adolescents) and 65% (177 of 271 mothers). Structural model results showed that T1 anti-immigrant worry and behavioral modification was associated with T3 increases in externalizing symptoms indirectly through T1 to T2 increases in parent-child conflict (β = 0.03; SE = 0.02; 95% CI, 0-0.08). For girls, T1 family member deportation or detention was associated with T1 to T3 increases in internalizing and externalizing symptoms indirectly through T1 to T2 declines in parental support (internalizing: β = 0.04; SE = 0.02; 95% CI, 0-0.08; externalizing: β = 0.03; SE = 0.02; 95% CI, 0-0.07). Sensitivity analyses supported structural model findings. Results of this cohort study suggest that legislative bodies, the health care system, and educational institutions should implement safeguards to mitigate potential harm conferred by anti-immigrant environments for parent-child relationships and, in turn, Latinx adolescents' mental health.

CHARACTERISTICS OF THE EMOTIONAL INTELLIGENCE OF YOUNG PEOPLE WITH DIFFERENT ACCENTUATIONS OF CHARACTER

The purpose of the work is to show the results of a theoretical and empirical study of the features of the emotional intelligence of young people with different accents and styles of humor. Methodology. 88 young men of late adolescence took part in the study - students of Kyiv secondary schools. Methods: 1) theoretical analysis and generalization of scientific literature on research issues; 2) diagnostic standardized methods: diagnostic test of character accentuation types (A.E. Lychko); emotional self-awareness test (O.I. Vlasova); questionnaire of emotional intelligence (D.V. Lusin); empathy questionnaire (Mehrabiana); questionnaire "Styles of humor" (Martin; 3) Descriptive statistics and the Pearson correlation coefficient were used to analyze the relationships between the results of the empirical study. The results. The researchers found that the most developed interpersonal emotional intelligence is characteristic of young people with a labile accentuation type, who are characterized by low self-awareness and high mood variability. High intrapersonal emotional intelligence is significantly associated with the astheno-neurotic type of accentuation, which is characterized by increased mental and physical fatigue and irritability in everyday life. This type of accentuation of the character turned out to be predominant among the researched (22%). Regarding the use of humor by the researched people, it was found that young men with demonstrative and hyperthymic types of character accentuations prefer an aggressive style of humor, which is destructive in content and directed at others. This significantly distinguishes them from young men of the age-standard development, for whom the most characteristic is a self-supporting style of humorous attitude to life events, which has a constructive meaning and productively affects the personality of the young man and his environment.

Vaporized nicotine in utero results in reduced birthweight, increased locomotion, and decreased voluntary exercise, dependent on sex and diet in offspring.

Rationale Clinical research has shown that prenatal exposure to nicotine may result in increased obesity risk later in life. Preclinical research has corroborated this finding, but few studies have investigated inhaled nicotine or the interaction with diet on obesity risk. Objective The aim of this study was to investigate the effects of prenatal nicotine exposure on both direct and indirect obesity measures, with both sex and diet as factors. Methods Pregnant rats were exposed to either vehicle or nicotine vapor (24mg/mL or 59mg/mL) throughout the entire gestational period. Offspring from each treatment group were given either a normal diet or a high fat diet starting at postnatal day 22. Caloric intake, body weight, spontaneous locomotion, sleep/wake activity, and voluntary exercise were measured throughout adolescence. Pregnancy weight gain and pup birthweights were collected to further measure developmental effects of prenatal nicotine exposure. Results Both maternal weight gain during pregnancy and pup weight at birth were decreased with prenatal nicotine exposure. Early adolescent males showed increased spontaneous activity in the open field following prenatal nicotine exposure compared to vehicle counterparts, particularly those given high-fat diet. Additionally, high dose nicotine prenatal treated males ran significantly less distance on the running wheel in late adolescence compared to vehicle counterparts, in the normal diet group only. Conclusion The results presented here show decreased birthweight, hyperactivity, and decreased voluntary exercise in adolescence following prenatal nicotine exposure in dose, sex, and diet dependent manners, which could lead to increased obesity risk in adulthood.

Bullying Victimization as an Adverse Experience for Psychosocial Adjustment among Irish Adolescents

AbstractThis study investigates the long-term effects of victimization from middle adolescence to late adolescence and early adulthood, examining emotional and behavioral problems, peer relationships, and smoking habits and sleeping difficulties. The study also explores how these outcomes can persist into early adulthood, taking into consideration early victimization experiences, gender, cognitive ability, and family social class. The total sample included 7525 participants, spanning the ages of 13, 17, and 20, from the Child Cohort of the Growing Up in Ireland study (48.9% male). The path analysis model suggests that victimization is associated with behavioral problems at age 17, and it is also linked to emotional problems and sleeping difficulties at both ages 17 and 20. Additionally, sleeping difficulties, smoking habits, and indices of emotional and behavioral adjustment exhibit some stability between ages 13 and 17, as well as 17 and 20. Theoretical and practical implications are discussed.

The impact of cultural experiences on mental health, career readiness and decision making in late adolescence: an international school qualitative interview study

ABSTRACT In a globalised world, study and work options have become vast. The complexity of this for young people with an international upbringing can be considerable. This qualitative interview study aims to explore how different cultural experiences in childhood may influence career decision making behaviours, career preparedness and mental health in late adolescence, specifically within an international school setting. By considering the validity of these experiences, a better understanding of the psychological, social and cultural dynamics can be weighed up in order to identify suitable career guidance strategies to effectively support these young people. Using an IPA approach, in-depth semi-structured interviews were conducted with four diverse international school students aged 17–18. These young people demonstrated that career decision making was influenced by their cultural experiences, with cultural identity and sense of belonging having a significant impact on their career decision making and their perceived career adaptability in readiness for entering the globalised workforce.

Metabolomic signatures for blood pressure from early to late adolescence: findings from a U.S. cohort.

Metabolite signatures for blood pressure (BP) may reveal biomarkers, elucidate pathogenesis, and provide prevention targets for high BP. Knowledge regarding metabolites associated with BP in adolescence remains limited. Investigate the associations between metabolites and adolescent BP, both cross-sectionally (in early and late adolescence) and prospectively (from early to late adolescence). Participants are from the Project Viva prospective cohort. During the early (median: 12.8years; N = 556) and late (median: 17.4years; N = 501) adolescence visits, we conducted untargeted plasma metabolomic profiling and measured systolic (SBP) and diastolic BP (DBP). We used linear regression to identify metabolites cross-sectionally associated with BP at each time point, and to assess prospective associations of changes in metabolite levels from early to late adolescence with late adolescence BP. We used Weighted GeneCorrelation Network Analysis and Spearman's partial correlation to identify metabolite clusters associated with BP at each time point. In the linear models, higher androgenic steroid levels were consistently associated with higher SBP and DBP in early and late adolescence. A cluster of 59 metabolites, mainly composed of androgenic steroids, correlated with higher SBP and DBP in early adolescence. A cluster primarily composed of fatty acid lipids was marginally associated with higher SBP in females in late adolescence. Multiple metabolites, including those in the creatine and purine metabolism sub-pathways, were associated with higher SBP and DBP both cross-sectionally and prospectively. Our results shed light on the potential metabolic processes and pathophysiology underlying high BP in adolescents.

Internet use and its association with physical activity among adolescents in Beni Municipality, Myagdi, Nepal.

Adolescence is a critical phase marked by distinct health and developmental needs and rights. It represents a pivotal time for the acquisition of knowledge, skills, emotional regulations, and relationship management. However, a recent surge in internet usage among adolescents has been observed, leading to a concerning decline in physical activity. This study aims to evaluate the level of physical activity and its correlation with internet use among adolescents. A cross-sectional study, conducted within educational institutions in Beni, Nepal, utilized a self-structured questionnaire to collect data on physical activity levels and associated factors. The relationship between physical activity and independent variables was assessed through the chi-square test, and regression analysis was employed to quantify the strength of this association. The study revealed that 75.3% of adolescents (out of 385) exhibited inadequate physical activity levels. Notably, late adolescents were more susceptible to insufficient physical activity than their middle adolescent counterparts were. Adolescents from nuclear families (UOR = 2.689, C.I = 4.074-22.822), those with higher monthly family income (UOR = 3.318, C.I = 1.209-9.105), and individuals using Wi-Fi (UOR = 1.801, C.I = 1.117-2.904) demonstrated a higher likelihood of internet addiction. Moreover, these groups were more prone to engage in inadequate physical activity (UOR = 1.1740, C.I = 0.938-3.226) compared to their counterparts not addicted to the internet. The study concludes that over two-thirds of adolescents were addicted to the Internet, and three-fourths were inadequately physically active, with late adolescents being more affected than middle adolescents. Inadequate physical activity was associated with various factors, including family type, monthly family income, monthly pocket money, father's occupation, type of school, type of internet access, and Internet Addiction Test (IAT) score. Internet-addicted adolescents were found to be more likely to be physically inactive.

Longitudinal associations between attachment representations coded in the adult attachment interview in late adolescence and perceptions of romantic relationship adjustment in adulthood

AbstractIncreasingly, researchers have operationalized Adult Attachment Interview (AAI)‐derived attachment representations as reflecting individual differences in secure base script knowledge (AAIsbs) – the degree to which individuals show awareness of the temporal‐causal schema that summarizes the basic features of seeking and receiving effective support from caregivers when in distress. In a series of pre‐registered analyses, we used AAI transcripts recently re‐coded for AAIsbs and leveraged a new follow‐up assessment of the NICHD Study of Early Child Care and Youth Development cohort at around age 30 years (479 currently partnered participants; 59% female; 82% White/non‐Hispanic) to assess and compare the links between AAIsbs and traditional AAI coding measures at around age 18 years and self‐reported romantic relationship quality in adulthood. Higher AAIsbs predicted better dyadic adjustment scores in adulthood (r = 0.17) and this association remained significant controlling for other AAI‐derived coding measures, as well as sociodemographic and cognitive functioning covariates. Findings extend previous evidence pointing to the predictive significance of AAIsbs for multiple adult functioning domains.

Trajectory of depressive symptoms over adolescence in autistic and neurotypical youth

BackgroundAdolescence coincides with a dramatic rise in the onset of psychiatric conditions including depression. Depression symptoms may be particularly prevalent and impairing for youth with autism spectrum disorder (ASD). While prior research suggests adolescence is associated with worsening depression symptoms for typically developing (TD) and autistic youth, it is unclear if they follow a similar course.MethodThe study examined the trajectory of depressive symptoms in autistic and neurotypical youth over a 4-year longitudinal study using linear and logistic mixed effects models. In youth with clinically relevant depressive scores (t-score > 65), moderating factors (i.e., diagnosis, age, puberty, sex) were explored. During Year 1, the sample included 244 youth 10-to-13 years: 140 in the ASD group (36 females) and 104 in the TD group (46 females).ResultsAutistic youth had elevated depression scores compared to TD peers (p < 0.001) and females were higher than males in both groups (p = 0.001). There was significant diagnosis by age (p < 0.001) and diagnosis by pubertal stage (p < 0.05) interactions. In the ASD group, elevated depressive scores presented in early adolescence and decreased during middle adolescence and puberty, whereas the TD group showed the opposite trend with an increase in depression symptoms with advancing development.LimitationsLimitations include an unequal sex distribution (fewer females), non-representative autistic sample (e.g., cognition and race/ethnicity), and potential confound of the COVID-19 pandemic.ConclusionsAutistic youth present with higher rates of depressive symptoms early in development; yet, approaching middle adolescence and puberty, the symptom trajectory in the autistic youth declines coinciding with an increase in the TD youth. While group trajectories are divergent, they lead to similar levels of depression in late adolescence with higher symptoms in females. Findings suggest a period of quiescence in depressive symptomology influenced by biopsychosocial factors impacting affective profiles.

Unveiling Socioeconomic Disparities: Understanding Pregnancy Awareness and Family Well-being among Middle-Late Adolescent Mothers across Diverse Socioeconomic Strata in Urban Manila, Philippines

This research study examines the real-life experiences of adolescent mothers within the age group of 13-17 years old (middle adolescence) to 18-21 years old (late adolescence), coming from middle and low socioeconomic backgrounds. Using different qualitative research techniques, this study aims to uncover unique obstacles, coping strategies, and support networks encountered by teenage mothers from different economic strata. A total of 6 teenage mothers from middle-class (n=3) and low-income (n=3) settings is conducted to gather their stories and perspectives. Thematic analysis is employed to discern common threads and distinctions between the two groups, creating themes to categorize the similarities between their responses. The outcomes of this inquiry offer valuable insights into how socioeconomic status intersects with teenage parenthood, underscoring four significant factors that emerged through the data analysis: Support Systems, Educational and Career Trajectory, Family Dynamics and Expectations, and Awareness and Perception. Having identified these themes can design a path towards creating customized interventions and support mechanisms for both vulnerable demographics while advocating for more inclusive and educational programs in raising awareness and removing the stereotypes about teenage pregnancy. For future researchers interested in studying the real-life experiences of adolescent mothers from different economic backgrounds, it is essential to consider the myriad of factors that shape their lives. These factors include race, culture, and geographical location, all of which intersect with their socioeconomic status to influence their experiences.

Relationships between emotion regulation strategies and executive functions in adolescence: Exploring the effects of discrete emotions and age.

Emotion regulation (ER) develops during adolescence and contributes to psychosocial adjustment. Individual differences in the development of ER strategies may be related to cognitive processes responsible for managing goal-directed behaviors, namely executive functions (EFs). This study examined (1) examined how difficulties in specific EFs (i.e., inhibition, flexibility and working memory) predict the use of ER strategies (i.e., reappraisal, distraction, expressive suppression, rumination, support-seeking) in an emotion-specific approach and (2) investigated these links across three different age groups (corresponding to early, middle and late adolescence), considering the nonlinear evolution of the relationships between EF and ER strategies during adolescence. The sample was composed of 1076 adolescents aged from 12 to 19 years old who completed questionnaires on EF difficulties (i.e., inhibition, flexibility, and working memory) and ER strategies (i.e., distraction, reappraisal, expressive suppression, social support-seeking, and rumination). Results showed various complex relationships between EFs and ER. Flexibility issues were related to rumination at all ages, while inhibition and flexibility difficulties were negatively linked to reappraisal in mid- to late adolescence. Many relationships were emotion- and age-dependent. These findings support the link between cognitive and emotional regulatory processes. Its complex evolution during adolescence opens a new avenue for future research.

Examining the Empathy factors in Science Class (EfSC) Between Early and Late Adolescents

Objectives This study aims to validate the Empathy factors in Science Class (EfSC; Chun et al., 2018) as a measure for scientific empathy in early and late adolescents. Methods The instrument consists of scientific empathy with others and empathy with the problem situation. To achieve this objective, a survey was conducted on 215 middle school students (early adolescents) and 473 high school students (late adolescents). Confirmatory factor analysis and multi-group analysis were employed to validate the instrument. Additionally, domain-general aspects of EfSC were explored by correlating empathetic factors with the Interpersonal Reactivity Index (IRI; Davis, 1980) and scientific inquiry ability with the Test of Science Process Skills (TSPS: Kwon &amp; Kim, 1994). Results The results revealed a high correlation between most factors of EfSC and IRI, indicating convergent validity. However, a relatively low correlation was observed with TSPS, suggesting a domain-specific nature of EfSC. Analysis of group features based on age and gender showed that factors related to empathy with others were influenced by age and gender, while factors related to empathy with problem situations were influenced by the interaction of age and gender. Further exploration indicated that females and high school students exhibited superior abilities in empathizing with others. In contrast, males, especially high school students, demonstrated higher abilities in empathy with problem situations. An analysis of variance (ANOVA) supported these findings. Conclusions This study contributes to the ongoing discourse on whether EfSC is a suitable instrument for assessing scientific empathy across the adolescence span. The nuanced differences observed in empathy factors based on age and gender underscore the importance of considering developmental and gender-related variations in assessing scientific empathy.

Association between trajectories of the neighborhood social exposome and mental health in late adolescence: A FinnTwin12 cohort study

BackgroundAdolescent mental health problems impose a significant burden. Exploring evolving social environments could enhance comprehension of their impact on mental health. We aimed to depict the trajectories of the neighborhood social exposome from middle to late adolescence and assess the intricate relationship between them and late adolescent mental health. MethodsParticipants (n = 3965) from the FinnTwin12 cohort with completed questionnaires at age 17 were used. Nine mental health measures were assessed. The social exposome comprised 28 neighborhood social indicators. Trajectories of these indicators from ages 12 to 17 were summarized via latent growth curve modeling into growth factors, including baseline intercept. Mixture effects of all growth factors were assessed through quantile-based g-computation. Repeated generalized linear regressions identified significant growth factors. Sex stratification was performed. ResultsThe linear-quadratic model was the most optimal trajectory model. No mixture effect was detected. Regression models showed some growth factors saliently linked to the p-factor, internalizing problems, anxiety, hyperactivity, and aggression. The majority of them were baseline intercepts. Quadratic growth factors about mother tongues correlated with anxiety among sex-combined participants and males. The linear growth factor in the proportion of households of couples without children was associated with internalizing problems in females. LimitationsWe were limited to including only neighborhood-level social exposures, and the multilevel contextual exposome situation interfered with our assessment. ConclusionsTrajectories of the social neighborhood exposome modestly influenced late adolescent mental health. Tackling root causes of social inequalities through targeted programs for living conditions could improve adolescent mental health.

Visual impairment and cognitive performance: A nationwide study of 1.4 million adolescents.

Previous research highlights the adverse effects of visual impairment (VI) on academic achievement in children, yet its impact on cognitive performance among adolescents and young adults remains under-studied. Therefore, this investigation aimed to analyse this association in a nationwide sample of Israeli adolescents. A retrospective population-based cross-sectional study was conducted among 1,410,616 Israeli-born adolescents aged 16-19 years, who were assessed before mandatory military service between 1993 and 2017. The definition of VI was based on best-corrected visual acuity (BCVA) measurements using a standard Snellen chart. Adolescents with BCVA worse than 6/9 in either or both eyes were classified as having unilateral or bilateral VI, respectively. Cognitive performance was measured using the General Intelligence Score (GIS), based on a validated four-domain test. Relationships were analysed using regression models yielding adjusted odds ratios (ORs) for low (<-1 standard deviation [SD]) and high (≥1 SD) cognitive Z-scores. Of 1,410,616 adolescents (56.1% men), 13,773 (1.0%) had unilateral and 3980 (0.3%) had bilateral VI. Unilateral VI was associated with adjusted ORs for low and high cognitive Z-scores of 1.24 (1.19-1.30) and 0.84 (0.80-0.89), respectively. ORs were accentuated for bilateral VI, reaching 1.62 (1.50-1.75) and 0.81 (0.74-0.90) for low and high cognitive Z-scores, respectively. Cognitive performance subscores mirrored these results, with the visual-spatial functioning subtest demonstrating the greatest effect size. These associations persisted in sub-analyses restricted to adolescents with amblyopia-related VI, mild VI and unimpaired health status. Visual impairment, including mild and unilateral cases, is associated with reduced cognitive performance scores assessed in late adolescence. Further research is required to gain a comprehensive understanding of the dynamics underlying this relationship.

The Love Problem of a Student-Revisited: A Psycho-Ethical Map for Cases of Anima Projection.

In its typical form, an "anima projection" is a psychic experience in which a heterosexual man is caught up by an intense, almost magical attraction for a woman. What sets these numinous experiences apart from a common "crush" is a pattern of specific phenomenological characteristics. Anima projections are particularly common in late adolescence and early adulthood, when they can cause a deep sense of disorientation. Little education exists for young men on how to deal with these experiences and to actualize the developmental opportunity that underlies them. In this paper, I frame anima projections as an ethical problem and outline a psycho-ethical "map" that is intended for use by disoriented young men, or by any practitioner who may be tasked with helping them navigate this challenge along the path of individuation. The map considers four solutions to the love problem: the "concretistic-literal", the "fearful-avoidant", the "rational-depressive", and the "transitional-developmental" solution, and indicates the latter as the one that is conducive to optimal psychic development. Although developed with a focus on young men, the map may apply to other relations based on projection, regardless of age, sex, gender, or sexual orientation.
