Age-related changes in ventrolateral prefrontal cortex activation are associated with daily prosocial behaviors two years later

As adolescents acquire agency and become contributing members of society, it is necessary to understand how they help their community. Yet, it is unknown how prosocial behavior develops in the context of community-based prosocial behaviors that are relevant to adolescents, such as donating time to charities. In this longitudinal functional magnetic resonance imaging study, adolescents (N=172; mean age at wave 1=12.8) completed a prosocial task annually for three years (N=422 and 375 total behavioral and neural data points, respectively), and 14 days of daily diaries reporting on their prosocial behaviors two years later. During the task, adolescents decided how many minutes they would donate to a variety of local charities. We found that adolescents donated less time to charities from early to mid adolescence. Longitudinal whole-brain analyses revealed declines in ventrolateral prefrontal cortex (vlPFC) activation, as well as inverted U-shaped changes in precuneus activation when adolescents donated their time from early to mid adolescence. A less steep decrease in vlPFC activation predicted greater real-life prosocial behaviors in youth’s daily lives two years later. Our study elucidates the neurodevelopmental mechanisms of prosocial behavior from early to mid adolescence that have enduring effects on daily prosocial behaviors in late adolescence.

Predictors of suicidal behaviors among school-going adolescents: a cross sectional study in Indonesia

BackgroundAdolescents are a high-risk age group for committing suicide, and the risk substantially increases from early to late adolescence. Adolescence also serves as critical time period for early detection and intervention to prevent suicidal behaviors. This study aimed to assess the prevalence of suicidality and identify significant predictors of suicidality among adolescents.MethodsA cross-sectional observational study was conducted between January-December 2023. Adolescents aged 14–18 years old (n = 2317) were consecutively recruited from 15 high schools across four provinces on Java Island in Indonesia. Self-reported validated instruments in Indonesian were used to assess sociodemographic profiles, self-esteem (RSES), hopelessness (BHS), loneliness (ULS-3), perceived social support (MSPSS), depression (PHQ-9), resilience (CD-RISC-10), suicidality (SBQ-R). With adjusted odds ratio (AOR) and 95% confidence interval (CI), binary logistic regression analysis was used to determine significant predictors of suicidality.ResultsThe prevalence of lifetime suicide ideation was 26.5%, lifetime suicide plans were 18.2%, lifetime suicide threat was 14.1%, and lifetime suicide attempt was 4.4%. The prevalence of 12-month suicide ideation was 43.1%. The following variables were identified and significantly associated with suicidality (p < 0.05): female students (AOR = 1.912; 95%CI:1.507–2.425), chronic illness (AOR = 2.886; 95%CI:1.545–5.389), low resilience (AOR = 1.347; 95%CI:1.036–1.750), low self-esteem (AOR = 2.020; 95%CI:1.578–2.585), low family support (AOR = 3.532; 95%CI:2.486–5.017), loneliness (AOR = 1.611; 95%CI:1.211–2.143), depression (AOR = 4.882; 95%CI = 3.861–6.175), and hopelessness (AOR = 1.602; 95%CI:1.154–2.224). Nagelkerke R square was 0.364 indicating the regression model explained 36.4% of variance in suicidality.ConclusionsOur study revealed several significant predictors of suicidality among adolescents which can be targeted to develop suicide prevention strategies.

Anhedonia is associated with overgeneralization of conditioned fear during late adolescence and early adulthood

BackgroundPavlovian fear paradigms involve learning to associate cues with threat or safety. Aberrances in Pavlovian fear learning correlate with psychopathology, especially anxiety disorders. This study evaluated symptom dimensions of anxiety and depression in relation to Pavlovian fear acquisition and generalization. Methods256 participants (70.31 % female) completed a Pavlovian fear acquisition and generalization paradigm at ages 18–19 and 21–22 years. Analyses focused on indices of learning (self-reported US expectancy, skin conductance). Multilevel models tested associations with orthogonal symptom dimensions (Anhedonia-Apprehension, Fears, General Distress) at each timepoint. ResultsAll dimensions were associated with weaker acquisition of US expectancies at each timepoint. Fears was associated with overgeneralization only at age 21–22. General Distress was associated with overgeneralization only at age 18–19. Anhedonia-Apprehension was associated with overgeneralization at ages 18–19 and 21–22. ConclusionsAnhedonia-Apprehension disrupts Pavlovian fear acquisition and increases overgeneralization of fear. These effects may emerge during adolescence and remain into young adulthood. General Distress and Fears also contribute to overgeneralization of fear, but these effects may vary as prefrontal mechanisms of fear inhibition continue to develop during late adolescence. Targeting specific symptom dimensions, particularly Anhedonia-Apprehension, may decrease fear generalization and augment interventions built on Pavlovian principles, such as exposure therapy.

Emotion Dynamics among Late Adolescents and Emerging Adults: The Role of Maternal Privacy Invasion Perceptions.

Prior research suggests that youth experience immediate emotional distress following privacy invasion, but it is unclear whether and how persistent privacy invasion over longer periods destabilizes the intrapersonal emotional regulatory functions that privacy serves. This study investigated whether late adolescents and emerging adults who reported different patterns of maternal privacy invasion over a full academic year showed differences in emotion regulation, as reflected by the frequency and lability of negative and positive emotional experiences. Participants were first-year university students (n = 349; 60.2% female) in Hong Kong, aged 17 to 24 (MT1 = 18.20, SDT1 = 1.10). They self-reported maternal privacy invasion perceptions and negative and positive emotions 16 times, at bi-weekly intervals. Latent class growth analyses divided participants into a Higher Invasion Perceptions group (24.9%), a Moderate Invasion Perceptions group (46.4%), and a Lower Invasion Perceptions group (28.7%). A one-way MANCOVA examined potential differences in negative and positive emotion dynamics across groups, indexed by frequency (means) and instability (mean square of successive differences and probability of acute change). In line with predictions, both the Higher Invasion and Moderate Invasion groups reported higher negative emotion frequency and instability, compared to the Lower Invasion group. However, groups showed no significant differences regarding positive emotion frequency and instability. The findings indicate that perceptions of maternal privacy invasion predict youth's negative emotion regulation processes over their first collegiate year. Prolonged, higher levels of maternal privacy invasion may disrupt the intrapersonal regulatory functions that privacy serves over time.

Risk of not being in employment, education or training (NEET) in late adolescence is signalled by school readiness measures at 4-5 years.

Not being in employment, education, or training (NEET) is associated with poor health (physical and mental) and social exclusion. We investigated whether England's statutory school readiness measure conducted at 4-5 years provides a risk signal for NEET in late adolescence. We identified 8,118 individuals with school readiness measures at 4-5 years and NEET records at 16-17 years using Connected Bradford, a bank of linked routinely collected datasets. Children were categorised as 'school ready' if they reached a 'Good Level of Development' on the Early Years Foundation Stage Profile. We used probit regression and structural equation modelling to investigate the relationship between school readiness and NEET status and whether it primarily relates to academic attainment. School readiness was significantly associated with NEET status. A larger proportion of young people who were not school ready were later NEET (11%) compared to those who were school ready (4%). Most of this effect was attributable to shared relationships with academic attainment, but there was also a direct effect. Measures of deprivation and Special Educational Needs were also strong predictors of NEET status. NEET risk factors occur early in life. School readiness measures could be used as early indicators of risk, with interventions targeted to prevent the long-term physical and mental health problems associated with NEET, especially in disadvantaged areas. Primary schools are therefore well placed to be public health partners in early intervention strategies.

Effects of Developmental Timing on Cognitive and Behavioral Profiles in Fetal Alcohol Spectrum Disorder: Considerations for Education.

Associations and families demand the need to raise awareness of the implications in the cognitive and behavioral development of children with Fetal Alcohol Spectrum Disorder (FASD) that affect their learning and school participation. This study aims to generate a profile of executive and behavioral functioning in children and adolescents diagnosed with FASD. A probabilistic sampling by clusters (associations for individuals with FASD) is applied. The sample is composed of 66 families from three associations. The BRIEF-2 and SENA tests were administered to assess executive and behavioral functioning domains. Data analysis found that the executive and behavioral functioning profile of individuals with FASD varies with age, with greater impairment in middle and late adolescence. Likewise, the domain of executive functioning most affected in any of the developmental stages is working memory. Finally, cognitive impairment in the executive functioning domains has a direct impact on the social and adaptive functioning of people with FASD.

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.

Empathy across three generations: From maternal and peer support in adolescence to adult parenting and child outcomes.

This study examined the development of empathic care across three generations in a sample of 184 adolescents in the United States (99 female, 85 male; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other groups), followed from their family of origin at age 13 into their parenting years (through their mid-30s). Mothers' empathic support toward adolescents at age 13 predicted teens' empathy for close friends across adolescence (13-19 years). Participants' empathic support for friends in late adolescence predicted more supportive parenting behavior in adulthood, which in turn was associated with their children's empathy at age 3-8 years. Results suggest that individuals "pay forward" the empathic care they receive from parents, and that skills developed in adolescent friendships may inform later parenting.

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. Level-II, prospective cohort, correlational study.

Education, employment, and care work over adulthood: gendered life course trajectories in Canada and Germany

ABSTRACT This article compares the education, employment, and care work biographical sequences of Canadian and German women and men from late adolescence into mid-adulthood. Through the lenses of comparative gendered life course theory and welfare regime theory, sequence and cluster analyses are used to determine the adult life course sequences of women and men in each country and to assess the extent to which they differ across contexts. The analyses reveal clear gender differences in work–family balance in labour market participation and unpaid care work. Groups also differ strongly on educational attainment, income, and family composition. Comparatively, gender differences are less marked in the Canadian context. These results suggest that differing gendered trajectories result in diverse outcomes depending on the national context, shaping different outcomes for women cross-nationally. Our findings highlight how historical and contemporary country-specific welfare state policies support or hinder women as active and productive members of society.

Talent development in female soccer: Developmental activities of professional players in England

ABSTRACT The activities soccer players engage in during their formative years are thought to significantly contribute to the acquisition of expert performance. Whilst this area has seen great interest in male players, there has been little research in females. The study examined developmental activities engaged in by professional female soccer players in England. 56 female soccer players that had either progressed to professional status in adulthood (professional), or did not (ex-academy), completed the Participant History Questionnaire. Professional players started engaging in soccer at an earlier age than their ex-academy counterparts, resulting in greater engagement in practice and play during childhood. During adolescence, professional players engaged in higher amounts of practice than ex-academy players. Engagement in competition and practice was rated as high in physical and cognitive effort by all, yet ex-academy players reported higher levels of physical effort during early adolescence, and cognitive effort during late adolescence. Findings provide an illustration of the talent pathways of professional female soccer players in England and may inform future talent development systems. Large interindividual variation in soccer-specific and other-sport activity data highlight the importance of further understanding the environments of individual soccer nations and their potential impact on the talent identification and development processes.

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.

Developmental changes in the endorsement of psychotic-like experiences from middle childhood through young adulthood

BackgroundChildren tend to endorse psychotic-like experiences (PLEs) at higher rates than adults, although little is known about how specific symptom endorsement changes across the span of development. Here we take an observational approach to examine trends in PLE endorsement by age in two non-clinical samples: one of school-aged children and another of late adolescents and early adults. MethodsProdromal Questionnaire-Brief (child and adult versions) responses were investigated in individuals ages 9–13 (n = 11865) and 16–24 (n = 3209) from the Adolescent Brain and Cognitive Development Study (ABCD) and the Multisite Assessment of Psychosis-risk Study (MAP), respectively. Item-level endorsement and distressing item frequencies were examined by age throughout both cohorts. ResultsUnusual perceptual experiences were generally endorsed more heavily in childhood, while other PLEs were endorsed in adolescents and adults up to 4.8 times more frequently than in children. Additionally, certain experiences were endorsed by as many as 73 percent of the older sample. ConclusionsConsiderations for the measurement of PLEs in childhood and adolescence are underscored. Findings from these two samples provide a window into the course of these PLEs and may serve as a scaffold for future research investigating normative versus risk-related experiences during development.

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.
