Emotional Intelligence with Self Esteem in Adolescents Who Have Experienced Child Abuse In Sorong City

Adolescence is often considered a transition period marked by significant changes. It is seen as a period of transition, a challenging age, and a time of searching for identity. At the same time, adolescence is also considered the threshold of adulthood because it involves uncertainty and lack of control. Family dynamics also tend to change during the adolescent phase, including increased conflict between teenagers and parents, changes in roles and responsibilities, and changes in expectations placed on teenagers. A mismatch between parental expectations and adolescent behavior can increase the risk of conflict, which in turn can lead to incidents of child abuse. This research aims to determine the relationship between emotional intelligence and self-esteem in adolescents who have experienced child abuse in Sorong City. The method used is quantitative research with a correlational design. A total of 64 teenagers aged 12-21 years and residing in Malagusa sub-district, Sorong City were participants in this research who were taken using a saturated sampling technique. Research measurements used the Wong & Law Emotional Intelligence Scale (WLES) and The Rosenberg Self Esteem Scale (RSES). The research data analysis method uses Pearson Correlation. The research results show that there is a significant positive relationship between emotional intelligence and self-esteem of 0.949 with a significance of 0.000 (p<0.01). This shows that emotional intelligence plays a major and important role in relation to the level of self-esteem of teenagers who have experienced child abuse in Sorong City.

Understanding what drives adolescent social media behaviours: Informing approaches for interventions

While much research has explored the impacts of social media use, less is known about what factors drive use. The present study examined the relationships between potential drivers of social media use; namely social media literacy, motivations, and internalisation of appearance ideals, and determined whether they work in combination or individually to predict a range of social media uses and behaviours over time, including intensity, frequency, exposure to fitness and celebrity content, photo editing, appearance comparisons, and types of use. Australian adolescent girls (n = 704) and boys (n = 938) aged 11–16 years completed online surveys at baseline and 6-month follow-up. Bivariate correlations and multiple regressions were performed separately by gender. Results revealed weak associations between drivers and found they uniquely contributed to social media behaviours, though this was dependent on use outcome. Thin- and muscular-internalisation were related to some appearance-focused use (e.g., comparisons, following celebrity and fitness accounts) among girls and boys, respectively. Critical thinking was associated with lower Snapchat use among boys and motivations were related to intensity and type of use (i.e., viewing, posting). These findings suggest multicomponent holistic interventions targeting numerous drivers may be most appropriate in modifying social media behaviours among adolescents.

Expose to high doses of folic acid during pregnancy causes adolescent anxiety- and depression-like behaviors in offspring mice

The effects of high doses of folic acid (FA) during pregnancy on anxiety- and depression-like behaviors in adolescent offspring mice were determined and the potential underlying mechanisms were elucidated. Pregnant C57BL/6 mice were randomly assigned to Control (2 mg/kg in feed), high FA (20 mg/kg in feed), and ultrahigh FA (40 mg/kg in feed) groups. The physiological development of the offspring, their preweaning neurobehavioral milestones, and adolescent behaviors indicative of anxiety and depression were assessed. High doses of FA during pregnancy delayed key developmental milestones such as pinna detachment, fur appearance, and incisor eruption. Furthermore, it triggered anxiety-like behavior in the passive avoidance test and led to depression-like behavior, as reflected by reduced movement distance in the center zone and decreased shuttling frequency in the light-dark box test and open field test. Additionally, brain tissues of the offspring exhibited increased expression of the microglia marker ionized calcium-binding adaptor molecule 1 and the Nod-like receptor protein 3 inflammasome. These findings suggest that high doses of FA during pregnancy may impair physiological development and increase the susceptibility of the offspring to anxiety- and depression-like behaviors, potentially mediated through the induction of low-grade inflammation in the brain.

Aggression as a Mediator Between Ineffective Parenting Practices and Adolescent Deviant Behaviors

ABSTRACT This study examined the mediating effect of aggression on the relationship between three ineffective parenting practices (weak supervision, inconsistent parenting, and low warmth) and adolescent deviance. Using structural equation modeling (SEM) and a nationally representative longitudinal sample of South Korean adolescents (N = 1,823), results showed that all three parenting practices significantly affected aggression, which, in turn, significantly influenced deviance. Aggression fully mediated the effects of weak supervision and inconsistent parenting on deviance, while partially mediating the relationship between low parental warmth and adolescent deviance. Based on the findings, theoretical and practical implications were discussed.

The Relationship Between Family Support and Teenage Activity in Youth Integrated Service post in Purwosari District, Surakarta

<div><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td align="left" valign="top"><p><em>Adolescence is a transition period from childhood to adulthood where a person experiences significant biological, psychological, and social changes. This development encourages more mature behaviors in adolescents related to various adolescent health problems, thus requiring comprehensive and integrated services that include all elements of different programs and sectors, such as the development of adolescent care health services in the form of an Adolescent Integrated Service Post. This study aimed to determine the relationship between family support and adolescents' activity in adolescent integrated service posts in Purwosari district, Surakarta, Central Java. This study is a quantitative study with a cross sectional design. This research was conducted from October to December 2023 in Purwosari Village, Laweyan District, Surakarta. The total population was 818 adolescents aged 15-19 years. The research sample was 80 adolescents selected by snowball sampling technique. The research instrument used a questionnaire. The research data were analyzed univariately and bivariately (chi-square test). The results showed a p-value = 0.028, which means that there is a relationship between family support and adolescents' activeness at the integrated youth service post in Purwosari Village. Recommendations given to the health department to improve the implementation of integrated service post activities aimed at adolescents so that it can run optimally and more often conduct activities that can arouse the interest of adolescents who do not participate in youth activities, as well as appeal to parents to encourage the younger generation to start actively participating in youth integrated service post activities.</em></p><p><em> </em></p></td></tr></tbody></table></div><strong><em>Keywords: Family Support, Adolescent Activities, Youth Integrated Service Post</em></strong>

Supporting the Conversational Behavior of Adolescents with Autism Spectrum Disorders with Self-Monitoring and a Video-Based Supplement.

Individuals with autism spectrum disorders (ASD) might demonstrate impairments in initiating and sustaining a conversation and experience conversational challenges such as question-asking and turn-taking. Conversational skills are pivotal for the social functioning of adolescents with ASD. The current investigation aimed to extend the available information on interventions addressing the conversational needs of adolescents with ASD. The research questions were: (a) What is the effect of self-monitoring, supplemented by a video-based model on the conversational skills of adolescent students with ASD? and (b) What is the acceptability of the intervention among the participating adolescents with ASD?. Appropriate conversational behavior of three students with ASD (aged 16-18 years) was assessed using a withdrawal design, during 10-min conversation sessions. Appropriate conversational behavior was defined as a sequence of a turn-taking response (i.e., waiting quietly until the speaker finished talking), followed by a verbal utterance which included (a) making a statement or responding on topic, and/or (b) asking a contextually appropriate "wh"- question. The independent variable consisted of a primary self-monitoring procedure and a daily video-based supplement. Treatment fidelity and treatment acceptability were also assessed. The conversational behavior of all participants consistently improved under the self-monitoring intervention with the video-based supplement. Self-monitoring with a video-based supplement can effectively support the conversational behavior in adolescents with ASD. This information can guide the evaluation and planning of appropriate interventions designed to improve limited conversational behaviors of adolescents with ASD.

Trends in Norwegian adolescents’ substance use between 2014 and 2022: socioeconomic and gender differences

BackgroundSubstance use is a global health concern and early onset among adolescents increases health risks. We explore national overall trends in prevalence and trends in socioeconomic inequalities in past year alcohol intoxication, cannabis use, and use of other illicit drugs among Norwegian adolescents (ages ∼ 15–19 years of age) between 2014 and 2022.MethodThe present study builds on data from a nationwide repeated cross-sectional survey collected in 2014–2016 (T1), 2017–2019 (T2), 2021 (T3) and 2022 (T4). In total 415,560 adolescents (50.3% girls) completed the questionnaire during the study period. Trends in socioeconomic inequalities were assessed using the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII).ResultsWhile the prevalence of alcohol intoxication remained fairly stable, the prevalence of cannabis and other illicit drug use increased between 2014 and 2022 among upper secondary school boys (13.3–17.6%, and 2.0–5.2%, respectively) and girls (8.8–12.8%, and 1.1–2.7%, respectively). Similar trends were observed among 10th-grade adolescents. Boys were more likely than girls to use cannabis or other illicit drugs, but the gender gap in cannabis use narrowed during the study period. Among upper secondary girls, use of cannabis and other illicit drugs was higher among those from less affluent backgrounds, with absolute and relative inequalities in cannabis use increasing between 2014 and 2022. Small inequalities in cannabis use and decreasing relative inequalities in the use of other illicit drug were observed among upper secondary boys.ConclusionsThe increasing use of cannabis and other illicit drugs among Norwegian adolescents is concerning. Future studies should explore the underlying causes of this rise and explore the complex factors influencing adolescent substance use behaviours. A comprehensive understanding of these factors is essential for developing targeted and effective interventions.

Subjective measurement of physical activity and sedentary behaviour in children and adolescents with cerebral palsy: a scoping review

Purpose Physical activity is essential for maintaining overall health. Cost-effective and easily administered outcome instruments are valuable for clinical practice and large-scale population studies. The scoping review aimed to identify and map subjective instruments developed or validated to measure habitual physical activity and/or sedentary behaviour in children and adolescents with cerebral palsy aged 0–18 years across all levels of the GMFCS-E&R. Materials and methods This scoping review was conducted in accordance with the JBI methodology for scoping reviews and searched the databases PubMed, CINAHL, Web of Science, Cochrane Database of Systematic Reviews, JBI Database of Systematic Reviews and Implementation Reports, Embase and Pedro to identify articles. Results From 288 full-text references, 13 studies met the inclusion criteria. Nine instruments measured habitual physical activity and/or sedentary behaviour in children and adolescents with cerebral palsy aged 18 months to 18 years. Six subjective instruments were tested for ambulatory children, while three instruments were tested in children and adolescents at GMFCS-E&R level I–V. Conclusion and implications Reporting of the psychometric properties were found on reliability in three instruments, while data on validity were reported in all instruments. Further studies assessing the psychometric properties of subjective instruments in the target population are needed.

Associations between real-life light exposure patterns and sleep behaviour in adolescents.

One of the most striking changes in the regulation of sleep-wake behaviour during adolescence is circadian phase delay. Light exposure synchronises circadian rhythms, impacting sleep regulation, however, the influence of real-life light exposure on sleep variations remains less clear. We aimed to describe the sleep and light exposure patterns of high school students with comparable schedules and socio-economic backgrounds, and to evaluate whether there was any association between them, considering chronotype. We analysed five school days and two free days of actigraphy records, from 35 adolescents (24 female, mean age: 16.23 ± 0.60). The sample was described using the Sleep Regularity Index (SRI), chronotype (actigraphy MSFsc), and self-reported diurnal preference (Morning/Evening Scale). Regression models were constructed to assess the impact of light exposure (daytime and nighttime) on subsequent sleep episodes; and to confirm whether the associations could be an indirect consequence of chronotype. Despite following similar routines, the SRI varied considerably (48.25 to 88.28). There was compatibility between the actigraphy proxy for chronotype and the self-reported diurnal preference, extracted using the circadian rhythm scale for adolescents. Less light exposure during the day was associated with later sleep onset and shorter sleep duration. An increase of 100 lux in average daytime light exposure advance of 8.08 minutes in sleep onset and 7.16 min in sleep offset. When the regressions were controlled for chronotype, these associations persisted. These findings facilitate discussions regarding the behavioural aspect of the impact of real-life light exposure on sleep and its potential as a target for interventions aiming to enhance adolescents' sleep quality.

Website-Based Flipbook Model on Changes in Adolescents' Dental and Oral Health Care Behavior

One of the risk factors that causes high levels of dental and oral problems is behavior. To overcome these problems, media is used as a tool, with a model website-based flipbook. It is hoped that this will be a solution to facilitate the education process to help teenagers improve their dental and oral health maintenance behavior. This research is to produce a website-based flipbook model that is feasible and its application is effective in changing the oral health care behavior of adolescents. The method used in this research is Research and Development (R&D) and the research design used is a Quasy Experiment Pretest- Posttest with a Control Group Design. Research subjects were 2 groups: The intervention of 42 people was modeled website-based flipbook control 40 people were given an animated video on dental and oral health. The research results show that website-based flipbooks are suitable as a model for improving adolescent dental and oral health maintenance behavior with expert validation results: 90.8% and p-value = 0.858. The results of the unpaired test stated that its application was effective in increasing knowledge (∆0.001), attitudes (∆0.001), actions (∆0.001), and reducing debris index scores (∆0.010) compared to the control group. The conclusion is the development of the website-based flipbook model and its implementation of effective changes in adolescent dental and oral health maintenance behavior.

Sex-related inequalities in current cigarette smoking among adolescents in Africa

IntroductionRisky behaviours, including tobacco use, are highly prevalent among adolescents worldwide. Although these behaviours are largely influenced by various sociodemographic factors, including sex, there is a paucity of regionally representative literature on the sex-related inequalities in cigarette smoking among adolescents in Africa. This study examined the sex-based disparities in current cigarette smoking among adolescents aged 13–15 years in Africa.MethodsThe present study employed a secondary analysis of nationally representative data on 45 African countries obtained from the Global Youth Tobacco Survey, accessible through the World Health Organization (WHO) Global Health Observatory. We used the online version of the WHO Health Equity Assessment Toolkit (HEAT) to generate the results.ResultsThe prevalence of current cigarette smoking among the adolescents surveyed ranged from 1.6% in Eritrea to 10.4% in Mali among the low-income countries, from 1.3% in Tanzania to 13.1% in Mauritania among the lower-middle-income countries, from 5.2% in Gabon to 15.3% in Mauritius among the upper-middle-income countries, and 14.7% in Seychelles, the only high-income country in the study. The absolute summary measure (D) showed diverse sex-related disparities in the burden of current cigarette smoking among adolescents across the sub-regions. In all countries surveyed, the prevalence of cigarette smoking was higher among male adolescents compared to females, except in Liberia and Mozambique, where female adolescents bore a more significant burden than their male counterparts. Furthermore, male adolescents were more burdened with high cigarette smoking prevalence than females in low-income countries such as Mali, Madagascar, Guinea, Burkina Faso, and The Gambia, where such disparities were most pronounced. Meanwhile, we found less disparity in the burden of cigarette smoking between male and female adolescents in most of the lower and upper-middle-income countries surveyed.ConclusionThis study sheds light on the sex-based inequalities in the prevalence of current cigarette smoking among adolescents in Africa. In contrast to female adolescents, male adolescents bear a greater burden of current cigarette smoking. The burden of cigarette smoking is most pronounced in low-income countries such as Mali, Madagascar, Guinea, Burkina Faso, and The Gambia. Conversely, in most of the lower and upper-middle-income countries surveyed, the burdens of current cigarette smoking among male and female adolescents were found to be less disparate. Consequently, cigarette smoking prevention programmes and strategies must be implemented in all African nations. There is also the need to intensify interventions aimed at altering the smoking behaviour of male adolescents. Policymakers can develop and implement evidence-based interventions to address the burden of cigarette smoking among the adolescents. Finally, existing policies and programmes addressing adolescents' cigarette smoking should be re-assessed and strengthened to achieve their objectives.

Psychological Dynamics among Adolescents with Self-Harm Behavior Based on Rational Emotive Behavior Therapy

The objective of this study was to ascertain the psychological underpinnings of self-harm behaviors among adolescents, with a particular emphasis on the tenets of rational emotive behavior therapy (REBT). Additionally, this study aimed to elucidate the various forms of self-harm behaviors and the underlying factors that contribute to these behaviors in adolescents. This research employed a qualitative approach with a phenomenological research design. The research subjects were students at State Senior High School 1 Batu, Indonesia, selected based on certain criteria in accordance with the research needs (purposive sampling). The results demonstrate three key aspects of the psychological dynamics of adolescents with self-harm behavior, namely cognitive, affective, and conative. These were mapped into the ABC model, which comprises three elements, namely activating events, irrational beliefs, and impacts. Forms of self-harm in adolescents include physical (slashing the hand) and non-physical (ignoring health, smoking, taking drugs, and staying up late). The background of adolescents committing self-harm behavior is influenced by both internal factors (dissatisfaction and loneliness) and external factors (family problems and modeling).

Effect of Parenting Style, attachment to parents and self-compassion on the occurrence and recovery motivation for non-suicidal self-injury in adolescents.

Non-suicidal self-injury (NSSI) is a worldwide mental health problem that deserves thorough investigation. This study aims to explore the effect of parenting styles, attachment to parents, and self-compassion on the occurrence of non-suicidal self-injury (NSSI) behavior in adolescents and whether these factors influence their recovery motivation. A total of 132 adolescents who had engaged in NSSI within the last year and 72 adolescents who had never engaged in NSSI were recruited from the Shenzhen Kangning Hospital and from primary and secondary schools and communities. Differences in the Hamilton Depression Scale (HAMD), Inventory of Parent and Peer Attachment (IPPA), Egma Minn av. Bardndosnauppforstran (EMBU), and Self-Compassion Scale (SCS) of participants were compared. A binary logistic model was established to measure the odds ratios of these variables on the occurrence of NSSI. In the NSSI adolescent sample, separate binary logistic models were created with NSSI impulse inhibition, NSSI resistance activity, and NSSI recovery motivation as dependent variables and with parenting styles, attachment to parents, and self-compassion as independent variables. Compared with adolescents with no NSSI behavior, those who had engaged in NSSI within the past year had higher scores on the HAMD, as well as higher EMBU-negative father parental behavior (punishment, excessive interference, rejection, and overprotection), EMBU-negative mother parental behavior (excessive interference, rejection, and punishment), and SCS negative self-compassion scores. Moreover, adolescents with NSSI had lower EMBU-father emotional warmth, EMBU-mother emotional warmth, IPPA-attachment to father, IPPA-attachment to mother, and SCS positive self-compassion scores. Current depressive symptoms and maternal punishment are risk factors for NSSI in adolescents, while positive self-compassion was a protective factor. Positive self-compassion can positively predict NSSI impulse inhibition, NSSI resistance activity, and NSSI recovery motivation. However, we unexpectedly found that the father's emotional warmth negatively predicts NSSI resistance activity. This study found that positive self-compassion has a significant impact on the prevention of and recovery from NSSI behavior in adolescents.

Understanding Peer Sexual Norms, Attitudes, and Pressure: Correlates of Risky Sexual Behaviours among Secondary School Adolescents in Anambra State, Nigeria

Aims: Sexual behaviour initiation often takes place throughout adolescence and is typically linked to engaging in unprotected sexual practices and other high-risk sexual behaviours. This research investigated the correlation between peer sexual behaviour, sexual attitudes, pressure to engage in sexual activity, and sexual risk behaviours among secondary school adolescents in Anambra State. Methodology: The study was carried out with a correlational research approach. The research included 1,200 individuals from a population of 19,048 SS2 teenagers in public secondary schools. Cronbach's Alpha statistics were used to evaluate the internal consistency of three scales: the Brief Sexual Attitudes Scale (BSAS), the Pressure to Have Sex Questionnaire (PTHSQ), and the modified Sexual Risk Behaviour Scale (SRBS). The reliability coefficients for the Adolescent Sexual Behaviour Index (ASBI) were 0.86, 0.96, and 0.80, respectively. The reliability index of the ASBI was determined using Kuder Richardson statistics, resulting in a coefficient of 0.86. The data was obtained by directly administering the instruments and processed using the Statistical Package for Social Sciences (SPSS). Pearson Product Moment Correlation is a statistical measure that quantifies the strength and direction of the linear relationship between two variables. Coefficients were used to address the research enquiries, while the null hypotheses were examined using a t-test to determine significant association. Results: The results indicated a weak positive association between the sexual conduct of peers, sexual attitudes, and pressure to engage in sexual activity, and sexual risk behaviours among secondary school teenagers in Anambra State. Furthermore, the findings demonstrated a notable association between these variables and the sexual risk behaviours of secondary school adolescents in Anambra State. Conclusion: Based on these data, it was determined that there is a weak positive link between peer sexual behaviour, sexual attitude, peer pressure to engage in sexual activity, and unsafe sexual behaviours among secondary school teenagers in Anambra State. Given this information, it is advisable for school administrators to establish health initiatives aimed at assisting young people in adopting enduring sexual habits that promote their overall health and well-being. These practices should also aim to minimise their susceptibility to HIV and other sexually transmitted diseases.

Menstrual waste behaviour of young adolescents: a theory of planned behaviour approach

ABSTRACT There is a significant rise in the pile of non-biodegradable menstrual waste. Still, the majority of the studies focused on the variety and quality of menstrual products, and only a few investigated the sustainable and safe disposal of used menstrual material. The theory of planned behaviour serves as the foundation upon which the paper constructs its theoretical framework to study menstrual waste disposal behaviour among adolescents. It finds that a variety of social contexts and circumstances influence adolescents' intentions to dispose of used menstrual products carelessly, indirectly contributing to environmental degradation. This paper is an attempt to examine the existing gap in the literature and understand the attitudes and intentions that underlie such an activity. This paper also suggests ways for policymakers and implementors to influence the behaviour of adolescents resulting in hygienic and environmentally safe disposal of menstrual waste.

90 The association between risk of depression and combined vigorous physical activity and screen time behaviours in French-speaking Belgian adolescents

Abstract Purpose While there is a clear consensus on the positive effect of physical activity on reducing the risk of depression, the literature on the association between screen time and risk of depression is rather conflicting. Also, no clear consensus has been reached on whether being sufficiently active could alleviate the negative effects of being sedentary on mental health. The purpose of this study was to investigate the association of combined vigorous physical activity (VPA) and screen time (ST) behaviours with the risk of depression (RD) in Belgian adolescents. Methods The analysis used data collected through self-reported questionnaires from 8412 adolescents aged 10 to 20 included in the 2022 “Health Behaviour in School-aged Children” (HBSC) study in French-speaking schools. RD was measured using the World Health Organisation Five Well-being Index (WHO-5), with scores ≤28/100 indicating RD. VPA and ST behaviours were identified by combining data on ST (TV, video games and internet use) and VPA in three categories: (1) low ST (total weekly ST < 4hours/day), independently of VPA; (2) high VPA-high ST (VPA≥3 times/week and total weekly ST ≥ 4hours/day) and (3) low VPA-high ST (VPA<3 times/week and total weekly ST ≥ 4hours/day). The association between RD and VPA-ST behaviours was measured using adjusted binary logistic regression. Results In 2022, 15.4% had low ST, 40.6% high VPA-high ST, and 44.0% low VPA-high ST behaviours. Moreover, 13.2% were at risk of depression. This prevalence was eight times higher in low VPA-high ST (62.9%) and four times higher in high VPA-high ST (29.5%) than in low ST (7.6%) adolescents. After adjusting for sociodemographic characteristics, body mass index and sleep duration, adolescents with low VPA-high ST behaviours were more likely to be at risk of depression (aOR=1.17, 95%CI: 1.31-2.35) compared to those with low ST, but this was not the case for those who had high VPA-high ST (aOR=1.18, 95%CI: 0.81-1.71). Conclusion These findings suggest that having either low ST or sufficient VPA may be protective for RD in adolescents. With ST increasing and PA remaining low in French-speaking Belgian adolescents, health promotion initiatives should continue to promote both PA and the reduction of sedentary behaviours in adolescents.

Neonatal paw pricking alters adolescent behavior in a sex-dependent manner and sucrose partially remediates the effects

Neonatal exposure to noxious stimuli such as repeated heel lances can cause behavior changes. In the NICU sucrose given prior to procedures attenuates the immediate behavioral response to noxious stimuli but may not ameliorate the long-term consequences, and treatment with 24 % sucrose can brain structure and behavior in adult rodents. We used a rat model to determine whether paw pricks during the neonatal period alter social interaction and/or paw withdrawal thresholds (PWT) in adolescence, and if 7 % sucrose mitigates these effects. One male and one female pup per litter was assigned to each of six experimental groups (no paw prick (control), 1 paw prick (1PP), or 2PP, ± sucrose). Hind paws were pricked once or twice each day between postnatal day (P)3 and P10. Social behavior and PWT were tested in adolescence using the modified social interaction test and von Frey filaments, respectively. Social behavior was altered in the 2PP group; total time interacting was lower in 2PP rats, primarily due to less time sniffing a play partner. Sucrose did not mitigate effects of paw prick but trended to alter social behaviors in males; it decreased time in contact but increased social motivation (movement toward a play partner). PWTs were higher in 2PP animals, this was not altered by sucrose. Thus, rat pups exposed to paw pricks in the neonatal period have some altered behaviors in adolescence. The nature of the behavioral changes is sex-dependent, but sucrose did not mitigate these changes.

Implications of Developmental 17-OHPC Exposure on the Mesocorticolimbic Serotonergic and Dopaminergic Pathways and Adolescent Mood-Related Behavior in Rats.

The synthetic progestin, 17-α-hydroxyprogesterone caproate (17-OHPC), is administered to pregnant individuals at risk for recurrent preterm birth during a critical period of fetal mesocorticolimbic serotonergic and dopaminergic pathway development. These pathways play an important role in regulating cognitive behaviors later in life. Despite this, there has been very little research regarding the potential long-term effects of 17-OHPC on the behavioral and neural development of exposed children. In rodents, developmental exposure to 17-OHPC disrupts serotonergic and dopaminergic innervation of the medial prefrontal cortex and impairs decision-making in complex cognitive tasks in adulthood. The present study tested the hypothesis that developmental exposure to 17-OHPC similarly disrupts the development of serotonergic and dopaminergic pathways within limbic targets and subsequent mood-related behaviors. Developmental 17-OHPC exposure significantly increased the density of serotonin transporter-IR fibers in CA1, CA2/3, and the suprapyramidal blade of dentate gyrus in hippocampus and significantly reduced the density of TH-IR fibers within the nucleus accumbens shell in males but had no effect in females during adolescence. Irregular microglia activational phenotype and number were also observed in the hippocampus of 17-OHPC-exposed males. Developmental 17-OHPC reduced the latency to immobility in males in the forced swim test but did not affect sucrose consumption in a sucrose preference test. These findings suggest that 17-OHPC exerts sex-specific effects on the development of mesocorticolimbic pathways and mood-related behavior in adolescence and highlight the need to investigate effects in adolescent children.

Social Media and Adolescents' Prosocial Behavior: Evidence of the Interaction Between Short Videos and Social Value Orientation.

Social media significantly influences adolescents' prosocial behavior. With smartphones becoming ubiquitous, short videos have emerged as the predominant social media format for adolescents. However, the effects of adolescents' engagement with short videos on their prosocial behavior remain uncertain. This study aims to address the problem of how short videos (content and consequences) affect prosocial behavior in adolescents, and simultaneously explores the differences of this effect among individuals with different social value orientations. The current study conducted two research laboratory experiments using the between-subject study design of two factors. Study 1 (N=148) reveals that viewing prosocial short videos significantly predicts adolescents' prosocial behavior more so than neutral short videos. The interaction between short video content and social value orientation on prosocial behavior illustrates that the encouraging impact of prosocial content is primarily evident in prosocial individuals, rather than in pro-self individuals. In Study 2 (N=152), we introduce new dimensions by assessing adolescents' response to varying consequences of the same prosocial behavior (ie, reward, punishment) within the short video context. Findings indicate that reward consequences significantly bolster adolescents' prosocial behavior, whereas punitive measures tend to adversely affect it. Furthermore, the interaction between the consequences of prosocial short videos and social value orientation suggests that prosocial individuals exhibit no significant behavioral difference between rewards and punishments; instead, the reward/punishment consequences notably influence the prosocial behavior of pro-self individuals. Short videos (content and consequences) and social value orientations interactively influence adolescents' prosocial behaviors. This study underscores the need to recognize individual differences in adolescents' use of short videos and its impact on their prosocial behavior, particularly highlighting the crucial role of their social value orientations. Practically, the research offers valuable insights for parents and professionals seeking to foster adolescents' prosocial behavior.
