Hanging Out With the Right Crowd: Peer Influence on Risk-Taking Behavior in Adolescence

Educational Needs of the Adolescent Transplant Recipient: A Developmental Approach to Understanding Transplant

BACKGROUND

As pediatric transplant patients reach adolescence, care teams must prepare them for an eventual transition to adult-oriented care. Care teams must provide patients with the necessary knowledge and skills to manage their medical needs independently, but the level of learning required to successfully self-manage a transplant is substantial. Furthermore, adolescence is also a dynamic developmental period that includes significant cognitive development and changes in social motivations.

METHODS

Within this report, we offer insights into some of the key developmental mechanisms of adolescence that may influence their learning in a medical context. We also review key concepts that should be included in patient education across a range of domains. Finally, we consider how patients with comorbid developmental disorders may require tailored education.

RESULTS

Key domains for education include (1) personal health history, (2) medication knowledge/adherence, (3) navigation of the healthcare system, and (4) communication with others about their health. Teams should intentionally track patient progress in their education, although few formalized tools are currently available to support tracking. Accommodations to learning for patients with developmental needs include varied instructional modalities (e.g., verbal, written, and modeling), opportunities to practice skills in a controlled manner, and establishment of family/community support that can persist into adulthood.

CONCLUSIONS

Education of transplant patients is a critical but long-term process that supports the successful transition to adulthood. Care teams should develop intentional plans to transfer knowledge and build skills across adolescence, while remaining open to adaptive approaches to support the learning of all patients.

The Ending Effect in the Domain of Gambling: The Effect of Gain-Loss Status on Economic Decision-Making

Previous studies have shown that people prefer risk-taking at the end of gambles, a phenomenon called the ending effect. By using the Guess Gambling Game, we investigated the impact of gain-loss status on the ending effect (Experiment 1) and whether and how this effect may be affected by time reference (Experiment 2) and gender (Experiment 1&2). In Experiment 1, we observed the ending effect only in the gain group. Furthermore, gender differences exist in the loss group behavior, females were more risk-averse than males, and males tend to investment more initially and then reduce their investment in a U-shaped pattern (Experiment 1&2). Next, in Experiment 2, the findings indicated that participants in the gain group made riskier decisions and were willing to allocate more money for additional decision opportunities, irrespective of the time conditions. Additionally, under time-limited condition, participants tended to make more decisions in the final round, aiming to maximize their choices times within the limited time. These results contribute to a better understanding of the boundary conditions surrounding the ending effect in risky decision-making and may offer a scientific basis for mitigating and intervening in irrational decision-making.

Beyond the Situation: Hanging Out with Peers now is Associated with Short-Term Mindsets Later

It is well-established that unstructured unsupervised socializing with peers (UUS) motivates deviance while in that specific context. In this article, we extend this situational view by arguing that repeated UUS may also gradually shape adolescents' norms and decision making beyond the situation. Specifically, we argue that UUS promotes short-term mindsets, i.e., an increased focus on present rewards at the expense of considering future consequences. We test this hypothesis with fixed-effects models, using longitudinal data from a representative sample of 1,675 adolescents from Zurich, Switzerland. Consistent with our preregistered predictions, more frequent UUS is associated with increased short-term mindsets. Thus, our finding suggests that the effects of UUS on later deviance might be driven by becoming more present-oriented. This link offers new insights into the developmental pathways toward adolescent delinquency and offers a potential target for intervention.

Online Gambling Patterns and Predictors of Problem Gambling Among Korean Adolescents During the COVID-19 Pandemic: A Cross-sectional Study

PURPOSE

This study examined online gambling patterns among Korean adolescents during the COVID-19 pandemic and identified predictors of problem gambling based on a socio-ecological model.

METHODS

It used nationally representative data from the 2020 National Survey on Youth Gambling Problems conducted by the Korea Center on Gambling Problems. This study selected a sample of 780 adolescents aged 13-18 years who reported having gambled online at least once in the last three months from the raw data of respondents. They were classified as the non-problem group and problem group according to the Gambling Problems Severity Scale (GPSS) of the Canadian Adolescent Gambling Inventory (CAGI). The predictive factors of problem gambling were analyzed by logistic regression analysis.

RESULTS

The prevalence of problem gambling was 24.6 %. Its predictors included intrapersonal [male (odds ratios, OR = 1.67); gambling prior to COVID-19 (OR = 2.08)] and interpersonal factors [frequent gamblers in peers (OR = 4.34); peer pressure (OR = 2.34)]. Social factors, such as gambling in online community (OR = 5.60), sports betting (OR = 53.24), and lotteries (OR = 17.03) were associated with problem gambling.

CONCLUSIONS

The major predictors of problem gambling among adolescent online gamblers included peer gambling and specific types of gambling. To prevent problem gambling, strategies targeting peer groups are essential. In addition, nurses need to share with families, schools, communities, and policymakers that online gambling, such as lotteries and sports betting, are high-risk of adolescent problem gambling, and recommend them to collaborate for stricter regulatory measures.

Identifying who adolescents prefer as source of information within their social network

Adolescents are highly influenced by their peers within their social networks. This social influence can stem from both unsolicited peer pressure and the active search for guidance. While extensive research examined the mechanisms of peer pressure, little is known about who adolescents prefer as a source of information. To address this gap, we conducted two independent studies using a novel social search paradigm that allows participants to choose which social sources they wish to observe. In both studies, adolescents demonstrated a preference for their friends over non-friends, as well as for peers who were perceived as trustworthy. Across both studies, we found mixed evidence for the role of perceived popularity as a selection criterion. Notable, study 2 revealed the significance of "cool", "admirable" and "acting mean" as additional characteristics of preferred peers, traits that are often associated with elevated peer status. It also revealed an interest for peers perceived as being smart. These findings highlight the active role adolescents have in choosing social sources and emphasize the importance of multiple peer characteristics. Future research should investigate whether adolescents' interest in these types of peers is contingent upon specific social contexts, age groups, and peer cultures.

Virtual agents and risk-taking behavior in adolescence: the twofold nature of nudging

Peer pressure can influence risk-taking behavior and it is particularly felt during adolescence. With artificial intelligence (AI) increasingly present in a range of everyday human contexts, including virtual environments, it is important to examine whether AI can have an impact on human's decision making processes and behavior. By using the balloon analogue risk task (BART) evaluating propensity to take risk, in this study 113 adolescents' risk-taking behavior was measured when playing alone and in the presence of either a robot avatar or human avatar. In the avatar conditions, participants performed the BART while the avatars either (1) verbally incited risk-taking or (2) discouraged risk-taking (experimental tasks). Risk-taking behavior in the BART was assessed in terms of total number of pumps, gain and explosions. Tendency to impulsivity was also evaluated, as well as the effects of age and gender on risky behavior. The main finding showed a significant effect of both avatars on risk-taking tendency, with riskier behavior during incitement than discouragement conditions, the latter being also substantially different from the playing-alone condition. The results of this study open up new questions in a very sensitive and timely topic and offer various insights into the effect of nudging on adolescents' behavior in virtual contexts.

Adolescent Aggressive Riding Behavior: An Application of the Theory of Planned Behavior and the Prototype Willingness Model

Cycling has always been popular in China, especially during the years when the government encouraged green travel. Many people participate in rides to ease traffic congestion and increase transfer convenience. Due to the disorganized and tidal nature of cycling, cyclists create many conflicts with other groups. Adolescents are vulnerable road users with a strong curiosity and risk-taking mindset. Identifying the factors influencing adolescents’ aggressive riding behavior can assist in developing strategies to prevent this behavior. An online questionnaire was used to collect data on bicycling among students in a middle school in Guangzhou, China. The theory of planned behavior (TPB) and prototype willingness model (PWM) have been applied to study travel behavior and adolescent risk behavior. To investigate the impact of psychological variables on adolescent aggressive behavior, we used TPB, PWM, TPB + PWM, and an integrated model. Behavioral intentions are greatly influenced by attitudes, subjective norms, and perceived behavioral control. Both descriptive and moral norms played a role in behavioral willingness. The integrated model explained 18.3% more behavioral variance than the TPB model. The social reactive pathway explained more variance in behavior than the rational path.

Perceived barriers to vegetable intake among urban adolescents from socioeconomically disadvantaged backgrounds: A qualitative study from the perspective of youth workers and teachers

Eating habits established during adolescence have been shown to track into adulthood. Adolescents from lower socioeconomic status groups tend to have lower intakes of vegetables as compared with their more affluent peers. However, there is limited evidence about the determinants of vegetable intake in this population group. Therefore, this study aimed to explore the barriers to vegetable intake in adolescents living in socioeconomically disadvantaged areas through the perspective of school teachers and youth workers. A total of 20 semi-structured interviews were conducted with post-primary school teachers and youth workers from disadvantaged areas in Dublin, Ireland. Thematic analysis was applied to analyze the data. Eleven themes were identified and fitted within the Socioecological Model of Health: adolescent's food preferences, lack of early exposure and familiarity with vegetables, lack of interest, knowledge and skills at the individual and family level, parenting practices around nutrition, living difficulties, peers' influence and social norms around nutrition, dual role of social media, lack of resources and support to promote healthy eating, competition between unhealthy food vs. vegetables, lack of adequate approaches & initiatives at the community and at the public policy levels, and lack of State support to promote healthy eating. Although several actions could be taken at the personal and interpersonal levels, more efforts are needed at the organizational, community and public policy levels to improve dietary choices and vegetable intake among adolescents in socioeconomically deprived areas. These findings will inform the development of tailored intervention strategies and policies for these vulnerable youths.

Playing by the Rules? An Investigation of the Relationship Between Social Norms and Adolescents' Hate Speech Perpetration in Schools

Hate speech is often discussed and investigated as an online phenomenon, while hate speech among adolescents in the real world (e.g., in schools) has rarely been researched. Consequently, not much is known about potential interpersonal correlates and theoretical frameworks that might help us better understand why adolescents engage in hate speech in offline environments. To add to the literature, this study investigates hate speech perpetration among young people by utilizing the Social Cognitive Theory; more specifically, the association between witnessing and perpetrating hate speech in schools, and whether this relation is weakened or strengthened by anti-hate speech injunctive norms and deviant peer pressure. The sample consists of 1719 young people (45.1% boys, 53.6% girls, 1.3% gender diverse) between 11 and 18 years old (M_age = 13.96; SD = .98) from 22 schools in Switzerland. Self-report questionnaires were administered to measure hate speech involvement and adolescents' perception of social norms (i.e., anti-hate speech injunctive norms and deviant peer pressure). Multilevel regression analyses revealed that witnessing and perpetrating hate speech were positively associated. Moreover, injunctive anti-hate speech norms were negatively related and deviant peer pressure positively related to hate speech perpetration. Finally, increasing levels of injunctive anti-hate speech norms weakened the relation between witnessing and perpetrating hate speech, whereas higher levels of deviant peer pressure strengthened this association. The findings demonstrate that the Social Cognitive Theory is a useful framework for understanding hate speech perpetration in schools. The results also highlight the importance of taking into account social norms and interpersonal relationships (e.g., within the class) when designing anti-hate speech prevention programs and not focusing solely on intrapersonal factors.

Digital Media Influence on Adolescents’ Behavior during the COVID-19 Pandemic: Self-Intravenous Injection of Lactobacilli Drinking Yogurt

During the coronavirus disease 2019 (COVID-19) pandemic, widened physical distance and social deprivation are being replaced with digital media use. The media’s social function has tremendously increased following the COVID-19 era and adolescents living in a media-saturated world are the most vulnerable subjects of all. Social media use can encourage risky behavior in adolescents. Posting videos related to risk behaviors on social media has been linked to jeopardizing not only mental health but also physical safety. Herein, we report a case of a 12-year-old boy who intravenously self-injected Lactobacilli drinking yogurt for the purpose of filming a video to post on social media. He was treated with antibiotics based on Lactobacilli sepsis that cured him without any complications. In order to reduce the risk-taking behavior of adolescents, social norms need to be straightened up, and the social responsibility of hosts is strongly recommended.

Linking Self-Control to Negative Risk-Taking Behavior among Chinese Late Adolescents: A Moderated Mediation Model

Negative risk-taking behaviors refer to voluntary behaviors that lead to more harm than good. Low self-control is a crucial predictor of adolescents’ negative risk-taking behavior, but its internal mechanisms require further exploration. To reveal the working process underlying the association between self-control and adolescents’ negative risk-taking behaviors, we investigated the mediation of regulatory focus and the moderation of sense of power. A total of 2018 students (37.6% males) from two universities in Guangzhou, China, participated in a survey that investigated their self-control, negative risk-taking behavior, regulatory focus and sense of power. The results revealed that after controlling for the adolescents’ sex and their parents’ educational level, prevention focus partially mediated the association between self-control and negative risk-taking behavior. Moreover, sense of power moderated the association between self-control and prevention focus. Furthermore, the association between self-control and negative risk-taking behavior through prevention focus was stronger among adolescents with a high sense of power than among those with a low sense of power. Therefore, our findings suggest that regulatory focus and sense of power might be the mechanisms that explain how self-control is related to negative risk-taking behavior. These results thus provide a foundation for the prevention of and intervention in adolescents’ negative risk-taking behavior.

Decision neuroscience and neuroeconomics: Recent progress and ongoing challenges

In the past decade, decision neuroscience and neuroeconomics have developed many new insights in the study of decision making. This review provides an overarching update on how the field has advanced in this time period. Although our initial review a decade ago outlined several theoretical, conceptual, methodological, empirical, and practical challenges, there has only been limited progress in resolving these challenges. We summarize significant trends in decision neuroscience through the lens of the challenges outlined for the field and review examples where the field has had significant, direct, and applicable impacts across economics and psychology. First, we review progress on topics including reward learning, explore-exploit decisions, risk and ambiguity, intertemporal choice, and valuation. Next, we assess the impacts of emotion, social rewards, and social context on decision making. Then, we follow up with how individual differences impact choices and new exciting developments in the prediction and neuroforecasting of future decisions. Finally, we consider how trends in decision-neuroscience research reflect progress toward resolving past challenges, discuss new and exciting applications of recent research, and identify new challenges for the field. This article is categorized under: Psychology > Reasoning and Decision Making Psychology > Emotion and Motivation.

What Does it Mean to be Susceptible to Influence? A Brief Primer on Peer Conformity and Developmental Changes that Affect it

Peer influence is a twofold process that entails a behavior by an agent of influence that elicits conformity from the target of influence. Susceptibility describes the likelihood that conformity will occur. This review focuses on factors that shape susceptibility to peer influence. We argue that conformity has two distinct sources. In some instances, conformity is a product of characteristics of the target of influence, operationalized as stable individual difference variables. Trait-like attributes associated with susceptibility to peer influence include conformity dispositions, social goals, resource acquisition strategies, vulnerabilities, and maturational status. In other instances, conformity is a product of the context in which the target is situated, operationalized as impermanent individual difference variables. State-like circumstances associated with susceptibility to peer influence include conditions of uncertainty, personal attributes that differ from the partner or group, perceived benefits of impression management, unmet social needs, and social referents and beliefs about their behavior. Empirical illustrations are provided. We close with a discussion of developmental changes hypothesized to impact variations in susceptibility to peer influence.

Neurofeedback-Augmented Mindfulness Training Elicits Distinct Responses in the Subregions of the Insular Cortex in Healthy Adolescents

Mindfulness training (MT) reduces self-referential processing and promotes interoception, the perception of sensations from inside the body, by increasing one’s awareness of and regulating responses to them. The posterior cingulate cortex (PCC) and the insular cortex (INS) are considered hubs for self-referential processing and interoception, respectively. Although MT has been consistently found to decrease PCC, little is known about how MT relates to INS activity. Understanding links between mindfulness and interoception may be particularly important for informing mental health in adolescence, when neuroplasticity and emergence of psychopathology are heightened. We examined INS activity during real-time functional magnetic resonance imaging neurofeedback-augmented mindfulness training (NAMT) targeting the PCC. Healthy adolescents (N = 37; 16 female) completed the NAMT task, including Focus-on-Breath (MT), Describe (self-referential processing), and Rest conditions, across three neurofeedback runs and two non-neurofeedback runs (Observe, Transfer). Regression coefficients estimated from the generalized linear model were extracted from three INS subregions: anterior (aINS), mid (mINS), and posterior (pINS). Mixed model analyses revealed the main effect of run for Focus-on-Breath vs. Describe contrast in aINS [R2 = 0.39] and pINS [R2 = 0.33], but not mINS [R2 = 0.34]. Post hoc analyses revealed greater aINS activity and reduced pINS activity during neurofeedback runs, and such activities were related to lower self-reported life satisfaction and less pain behavior, respectively. These findings revealed the specific involvement of insula subregions in rtfMRI-nf MT.

An in-school social norms approach intervention for reducing unhealthy snacking behaviours amongst 11-12-year-olds

OBJECTIVES

Adolescents tend to overestimate the extent of peers' unhealthy snacking consumption and such misperceptions have been associated with increased personal unhealthy snacking. This study aims to test whether a Social Norms Approach (SNA) intervention which challenges these misperceptions of peers' unhealthy snacking will have a positive effect on students' personal unhealthy snacking behaviours, related attitudes, and behavioural intentions.

DESIGN

A quasi-experimental study tested the effectiveness of an in-school SNA intervention (n = 163) compared to a control condition (n = 95) among 11-12-year-old students.

METHOD

Both conditions received healthy eating information, while students in the SNA intervention received additional normative feedback (outlining the discrepancies between perceived and actual unhealthy snacking of the majority based on baseline data) delivered through an interactive poster-making session. Students completed self-reported measures of personal unhealthy snacking, related-attitudes, behavioural intentions, and normative perceptions (descriptive and injunctive) at baseline, post-intervention, and at a 3-month follow-up.

RESULTS

Students who received SNA feedback were significantly less likely to overestimate peers' unhealthy snacking attitudes post-intervention (F(1,232) = 16.405, p < .001), and at 3-month follow-up consumed fewer unhealthy snacks (F(1,232) = 6.133, p = .014) and had less positive attitudes towards unhealthy snacking (F(1,198) = 8.779, p = .003). The changes in personal snacking attitudes at 3-month follow-up were mediated by changes in normative misperceptions about peers' unhealthy snacking attitudes post-intervention, which indicated that the reductions in normative misperceptions following SNA messages mediated the effect of the intervention.

CONCLUSION

The results indicate that in-school SNA interventions which challenge normative misperceptions constitute a promising strategy for reducing unhealthy snacking in young adolescents.

Longitudinal Associations of Substance Use Risk Profiles with the Use of Alternative Tobacco Products and Conventional Smoking among Adolescents

Although personality is associated with the onset of substance use (i.e., conventional smoking, alcohol use, and cannabis use) during adolescence, it is unclear whether personality traits are also associated with the onset of use of alternative tobacco products (ATPs), i.e., electronic cigarettes, shisha-pens, and water pipes. This study examines whether personality traits are associated with the onset of use of both conventional cigarettes and ATPs. Longitudinal data (baseline and 18-month follow-up) were used. The sample consisted of 1114 non-user adolescents (mean age = 13.36, SD = 0.93, 56% female) at baseline. To measure personality traits, the Substance Use Risk Profile Scale was used with four subscales: anxiety sensitivity, hopelessness, sensation seeking, and impulsivity. Structural equation models were conducted using Mplus 7.3. Results showed that both hopelessness and sensation seeking were associated with the onset of use of e-cigarettes and conventional cigarettes. Further, sensation seeking and impulsivity were associated with the onset of use of shisha-pens and water pipes. In conclusion, to prevent adolescents from using ATPs and/or conventional cigarettes, it is important to take their personality traits into account. More research on other (shared) risk factors and on more advanced stages of ATP use is needed before effective prevention strategies can be developed.

Adolescent decision making: A decade in review

Research in the past decade has highlighted the nuances of adolescent decision making. In this review article, we summarize several themes evident in the field of developmental science including the redefinition of adolescence and the ways in which adolescent decision-making capabilities converge with or diverge from those of adults. While the decision-making process is similar for adolescents and adults in contexts that encourage deliberation and reflection, adolescents and adults differ in contexts which preclude deliberation vis-à-vis high emotional arousal. We also discuss the reconceptualization of adolescent behavior, including risk taking, as adaptive. That is, characteristics of adolescence, including impulsivity, the importance of peers, and novelty seeking, are normative, evolutionarily advantageous, and essential for positive development. While these features manifest in negative, health-compromising ways (e.g., risky driving and criminal behavior), they also foster growth and exploration. We conclude with a discussion of potential avenues for future research.

Toward understanding the functions of peer influence: A summary and synthesis of recent empirical research

Compelling evidence demonstrates that peer influence is a pervasive force during adolescence, one that shapes adaptive and maladaptive attitudes and behaviors. This literature review focuses on factors that make adolescence a period of special vulnerability to peer influence. Herein, we advance the Influence-Compatibility Model, which integrates converging views about early adolescence as a period of increased conformity with evidence that peer influence functions to increase affiliate similarity. Together, these developmental forces smooth the establishment of friendships and integration into the peer group, promote interpersonal and intragroup compatibility, and eliminate differences that might result in social exclusion.

Atypical interoception as a common risk factor for psychopathology: A review

The inadequacy of a categorial approach to mental health diagnosis is now well-recognised, with many authors, diagnostic manuals and funding bodies advocating a dimensional, trans-diagnostic approach to mental health research. Variance in interoception, the ability to perceive one's internal bodily state, is reported across diagnostic boundaries, and is associated with atypical functioning across symptom categories. Drawing on behavioural and neuroscientific evidence, we outline current research on the contribution of interoception to numerous cognitive and affective abilities (in both typical and clinical populations), and describe the interoceptive atypicalities seen in a range of psychiatric conditions. We discuss the role that interoception may play in the development and maintenance of psychopathology, as well as the ways in which interoception may differ across clinical presentations. A number of important areas for further research on the role of interoception in psychopathology are highlighted.

Peer Presence Effect on Numerosity and Phonological Comparisons in 4th Graders: When Working with a SchoolMate Makes Children More Adult-like

Simple Summary

The presence of others helps us when we are good or an expert at something and hinders us when we are bad or novice. Such social facilitation or inhibition is well-documented in adults, but much less in children despite the omnipresence of peers throughout education. To explore potential peer presence effects on children’s academic performance, fourth-graders performed basic numerical and language skills (typically mastered at their age) either alone or with a schoolmate. For comparison, the same was performed in adults. We found that a schoolmate’s presence enabled children to perform more like adults, with a better response strategy and faster and less variable response times than children tested alone. This provides research-based evidence supporting pedagogical methods promoting collective practice of individually acquired knowledge. Future studies pursuing this hitherto neglected developmental exploration of peer presence effects on academic achievements might have the potential to help educators tailor their pedagogical choices to maximize peer presence when beneficial and minimize it when harmful. The present study also paves the way towards a neuroimaging investigation of how peer presence changes the way the child brain processes cognitive tasks relevant to education.

Abstract

Little is known about how peers’ mere presence may, in itself, affect academic learning and achievement. The present study addresses this issue by exploring whether and how the presence of a familiar peer affects performance in a task assessing basic numeracy and literacy skills: numerosity and phonological comparisons. We tested 99 fourth-graders either alone or with a classmate. Ninety-seven college-aged young adults were also tested on the same task, either alone or with a familiar peer. Peer presence yielded a reaction time (RT) speedup in children, and this social facilitation was at least as important as that seen in adults. RT distribution analyses indicated that the presence of a familiar peer promotes the emergence of adult-like features in children. This included shorter and less variable reaction times (confirmed by an ex-Gaussian analysis), increased use of an optimal response strategy, and, based on Ratcliff’s diffusion model, speeded up nondecision (memory and/or motor) processes. Peer presence thus allowed children to at least narrow (for demanding phonological comparisons), and at best, virtually fill in (for unchallenging numerosity comparisons) the developmental gap separating them from adult levels of performance. These findings confirm the influence of peer presence on skills relevant to education and lay the groundwork for exploring how the brain mechanisms mediating this fundamental social influence evolve during development.

Decision-Making Deficits in Adolescent Boys with and without Attention-Deficit/Hyperactivity Disorder (ADHD): an Experimental Assessment of Associated Mechanisms

Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) demonstrate increased levels of real-life risk-taking behavior like substance abuse and reckless behavior in traffic, which potentially originates in decision-making deficits. Using experimental gambling tasks, the current study investigated three potential underlying mechanisms: (1) risky vs. suboptimal decision making, (2) the complexity of decision-making strategies and (3) the influence of feedback. Participants were 181 male adolescents (81 ADHD, 100 Typically Developing (TD); M_age = 15.1 years). First, we addressed a common confound in many gambling tasks by disentangling risk seeking from suboptimal decision making, and found that ADHD-related decision-making deficits do not originate in increased risk seeking but in suboptimal decision making. Second, we assessed decision-making strategies with a Bayesian latent mixture analysis and found that ADHD-related decision-making deficits are characterized by the use of less complex strategies. That is, adolescent boys with ADHD, relative to TD adolescent boys, less often adopted strategies in which all characteristics relevant to make an optimal decision were integrated. Third, we administered two gambling task conditions with feedback in which adolescents experience the outcomes of their decisions and found that adolescents with ADHD performed worse relative to TD adolescents on both conditions. Altogether, this set of studies demonstrated consistent decision-making deficits in adolescent boys with ADHD: The use of less complex decision-making strategies may cause suboptimal decision making, both in situations with and without direct feedback on performance.

Evaluating an Adolescent's Decision-Making Capacity Whilst in the Harsh World of Detention

Reports of children participating in hunger strikes while detained in offshore detention centres raise interrelated ethical issues and recognizable challenges for the medical decision-makers at these sites. A composite case study, informed by reports in the public domain, is employed to explore the unique challenges of consent and decision-making in these circumstances and the perennial issues inherent in adolescents' developing capacity and autonomy. We present an amalgamated case of a fourteen-year-old adolescent who refused to consent to medical reversal of her hunger strike protest. The medical team became the final arbiter when her parents, who were also in detention, could not agree with each other even after mediation. The case explores the complexity of evaluating the adolescent's capacity to provide informed consent while influenced by the opinions of co-detainees in this extreme setting. We argue that the parents and the child had compromised decisional capacity due to the effects of detention. The challenges to the medical team are recognized and discussed. The team members faced a difficult dilemma and considered the competing values of the multiple cultural and ethical factors. Each team member integrated his or her own roles, duties, and discipline-specific professional guidelines with the primary goal of mitigating potential harms.

Peers' Choices Influence Adolescent Risk-taking Especially When Explicit Risk Information is Lacking

This study examines the impact of peers' previous cautious versus risky choices on adolescents' risk-taking depending on the level of information about the risk. Adolescents completed an adaptation of the BART that manipulated social influence (cautious and risky) and risk information (i.e., informed, noninformed). Results showed that social influence impacts adolescents' decisions on the noninformed BART but not on the informed BART. In the noninformed BART, the peers' cautious choices strongly decreased risk-taking and led to greater performance. The peers' risky choices increase adolescents' risk-taking, but this effect is limited to situations involving minimal risk. Thus social experience may be a specific social context that represents a valuable source of information during adolescence, especially in situations with high uncertainty.

Views on COVID-19 and Use of Face Coverings Among U.S. Youth

PURPOSE

Little is known about the views of U.S. youth on COVID-19 or their use of face coverings. Closing this gap could facilitate messaging to promote COVID-19 risk mitigation behaviors.

METHODS

In July 2020, a five-question text message survey was sent to 1,087 youth aged 14-24 years. Questions assessed youths' perceptions regarding the likelihood of contracting COVID-19, the potential impact of contracting COVID-19 on their lives, the possibility of spreading COVID-19 to others, and their use of face coverings around others with whom they do not live. Coding was conducted to assign responses to discrete categories and to identify common themes.

RESULTS

Of 1,087 eligible participants, 797 (73.3%) were included in analyses. Of these participants, 27.3% believed they would likely contract COVID-19 in the next few months, 90.3% believed contracting COVID-19 would have a moderate or significant impact on their lives, 86.0% were moderately or very concerned about spreading COVID-19, and 89.2% reported wearing face coverings all or most of the time. Factors affecting face covering use included the desire to avoid contracting and spreading COVID-19, peer influence, and policy mandates.

CONCLUSIONS

Youths' perceptions regarding the risk of contracting COVID-19 varied, but most believed their lives would be adversely impacted if this occurred. Most youth were concerned about spreading COVID-19 and wore face coverings, but many made exceptions to face covering use when around close contacts. Public health campaigns may be most effective if they leverage positive peer influence and appeal to youths' desire not to spread COVID-19 to others.

Social norms in adolescent risk engagement and recommendation

Social influence is an important determinant of adolescent risk-taking, but little is known about how social norms contribute to adolescents' tendency to recommend and engage in risky behaviours. Using the Adolescent Risk-taking Questionnaire, we assessed subjects' (n = 198, age = 10-26) propensity to engage in and recommend risk-taking as well as their perception of risk norms. Adolescents recommended risk-taking more often compared to children and young adults. Perceived social norms were the most important factor predicting engagement in risky behaviours, and adolescents perceived risk-taking to be more normative than children or adults. Our findings highlight two mechanisms that contribute to adolescent risk-taking, active recommendation and perceived social norms. On this basis, we discuss potential means to attenuate excessive adolescent risk-taking.

Risk Taking by Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD): a Behavioral and Psychophysiological Investigation of Peer Influence

Adolescents with ADHD demonstrate increased risk-taking behavior (RTB) like substance abuse and dangerous traffic conduct. RTB in adolescence is more likely under peer influence. The current investigation (1) tests the hypothesis that adolescents with ADHD are particularly susceptible to such influence and (2) tests whether groups differed in autonomic reactivity to peer influence. Adolescent boys between 12 and 19 years with (n = 81) and without (n = 99) ADHD performed the Balloon Analogue Risk Task twice. In the peer condition, a highly credible virtual peer manipulation that encouraged risk taking was added, in the solo condition this was absent. Autonomic reactivity was indexed by heart rate (HR), pre-ejection period (PEP) and respiratory sinus arrhythmia (RSA). All adolescents engaged in more risk taking in the peer condition relative to solo condition. Autonomic differences between groups were only found on PEP: a stronger sympathetic response to peer influence was observed in typically developing adolescents relative to adolescents with ADHD. Increased physiological stress (as indexed by PEP) in the peer relative to the solo condition predicted peer-induced risk taking in all adolescents. We conclude that susceptibility to peer influence is not exaggerated in ADHD but rather reflects a general tendency of adolescents. As adolescents experiencing peer influence as stressful are most susceptible to peer influence, we suggest that increasing resistance to peer influence may be an important treatment aim for these adolescents specifically.

When Do those "Risk-Taking Adolescents" Take Risks? The Combined Effects of Risk Encouragement by Peers, Mild-to-Borderline Intellectual Disability and Sex

Adolescents with mild to borderline intellectual disability (MBID) show more daily life risk taking than typically developing adolescents. To obtain insight in when these "risk-taking adolescents" especially take risks, we investigated main and interaction effects of (a) MBID, (b) sex, and (c) type of peer influence on risk taking. The Balloon Analogue Risk Task (BART) was used as a proxy of real-life risk taking. 356 adolescents (12-19 years, 51.7% MBID, 63.4% boys) were randomly assigned to one of three BART peer-influence conditions: solo (no peers), positive risk encouragement (e.g., 'You are cool if you continue') or negative risk encouragement (e.g., 'You are a softy if you do not continue'). The main finding was that boys with MBID took more risks than typically developing boys in the negative risk encouragement condition. Boys with MBID also took more risks in the negative risk encouragement condition compared to the solo condition, whereas typically developing boys did not. There were no such effects for girls. Surprisingly, boys with MBID took less risks in the solo condition than typically developing boys. We conclude that boys with MBID especially show high risk taking when peers belittle or threat with exclusion from the peer group. Prevention and intervention programs should specifically target boys with MBID to teach them to resist negative risk encouragement by peers.

Exploring Substance Use Tweets of Youth in the United States: Mixed Methods Study

BACKGROUND

Substance use by youth remains a significant public health concern. Social media provides the opportunity to discuss and display substance use-related beliefs and behaviors, suggesting that the act of posting drug-related content, or viewing posted content, may influence substance use in youth. This aligns with empirically supported theories, which posit that behavior is influenced by perceptions of normative behavior. Nevertheless, few studies have explored the content of posts by youth related to substance use.

OBJECTIVE

This study aimed to identify the beliefs and behaviors of youth related to substance use by characterizing the content of youths' drug-related tweets. Using a sequential explanatory mixed methods approach, we sampled drug-relevant tweets and qualitatively examined their content.

METHODS

We used natural language processing to determine the frequency of drug-related words in public tweets (from 2011 to 2015) among youth Twitter users geolocated to Pennsylvania. We limited our sample by age (13-24 years), yielding approximately 23 million tweets from 20,112 users. We developed a list of drug-related keywords and phrases and selected a random sample of tweets with the most commonly used keywords to identify themes (n=249).

RESULTS

We identified two broad classes of emergent themes: functional themes and relational themes. Functional themes included posts that explicated a function of drugs in one's life, with subthemes indicative of pride, longing, coping, and reminiscing as they relate to drug use and effects. Relational themes emphasized a relational nature of substance use, capturing substance use as a part of social relationships, with subthemes indicative of drug-related identity and companionship. We also identified topical areas in tweets related to drug use, including reference to polysubstance use, pop culture, and antidrug content. Across the tweets, the themes of pride (63/249, 25.3%) and longing (39/249, 15.7%) were the most popular. Most tweets that expressed pride (46/63, 73%) were explicitly related to marijuana. Nearly half of the tweets on coping (17/36, 47%) were related to prescription drugs. Very few of the tweets contained antidrug content (9/249, 3.6%).

CONCLUSIONS

Data integration indicates that drugs are typically discussed in a positive manner, with content largely reflective of functional and relational patterns of use. The dissemination of this information, coupled with the relative absence of antidrug content, may influence youth such that they perceive drug use as normative and justified. Strategies to address the underlying causes of drug use (eg, coping with stressors) and engage antidrug messaging on social media may reduce normative perceptions and associated behaviors among youth. The findings of this study warrant research to further examine the effects of this content on beliefs and behaviors and to identify ways to leverage social media to decrease substance use in this population.

Social Influence in Adolescent Decision-Making: A Formal Framework

Adolescence is a period of life during which peers play a pivotal role in decision-making. The narrative of social influence during adolescence often revolves around risky and maladaptive decisions, like driving under the influence, and using illegal substances (Steinberg, 2005). However, research has also shown that social influence can lead to increased prosocial behaviors (Van Hoorn et al., 2017) and a reduction in risk-taking (Braams et al., 2019). While many studies support the notion that adolescents are more sensitive to peer influence than children or adults, the developmental processes that underlie this sensitivity remain poorly understood. We argue that one important reason for this lack of understanding is the absence of precisely formulated models. To make a first step toward formal models of social influence during adolescence, we first identify three prominent verbal models of social influence in the literature: (1) social motivation, (2) reward sensitivity, and (3) distraction. We then illustrate how these can be translated into formal models, and how such formal models can inform experimental design and help identify developmental processes. Finally, by applying our formal models to existing datasets, we demonstrate the usefulness of formalization by synthesizing different studies with seemingly disparate results. We conclude with a discussion on how formal modeling can be utilized to better investigate the development of peer influence in adolescence.

Effect of peer presence on adolescents' risk-taking is moderated by individual self-esteem: An experimental study

Prior research suggests that the presence of peers increases adolescents' risk-taking. However, it is not clear whether the effect of peer presence is moderated by individual characteristics such as self-esteem, since individuals with low self-esteem are more susceptible to peer influence theoretically. The present study examined this problem using an adapted Stoplight Game in an experiment. A final sample of 140 adolescent students aged 14-18 (M = 16.25 ± 0.73 years, 61 girls), divided into two groups-low self-esteem and high self-esteem, according to their self-esteem scores, completed a risk-taking task either alone or in the presence of a same-sex peer. The results indicated that peer presence increased adolescents' risk-taking, specifically for those with low self-esteem, while those with high self-esteem were not affected by peer presence. The findings are helpful for our understanding of peer influence on adolescent risk-taking and the moderating role of the self and have practical implications for preventing and intervening adolescents' risk-taking via increasing their self-esteem.

Differential effects of parent and peer presence on neural correlates of risk taking in adolescence

Adolescence is a developmental period associated with increased health-risk behaviors and unique sensitivity to the input from the social context, paralleled by major changes in the developing brain. Peer presence increases adolescent risk taking, associated with greater reward-related activity, while parental presence decreases risk taking, associated with decreased reward-related activity and increased cognitive control. Yet the effects specific to peers and parents are still unknown. The current functional magnetic resonance imaging (fMRI) study compared within-person peer and parent influences on risky decision-making during adolescence (ages 12–15 years; N = 56). Participants completed the Yellow Light Game (YLG), a computerized driving task, during which they could make safe or risky decisions, in the presence of a peer and their parent. Behavioral findings revealed no effects of social context on risk taking. At the neural level, a collection of affective, social and cognitive regions [ventral striatum (VS), temporo-parietal junction (TPJ), and dorsolateral prefrontal cortex (dlPFC)] was more active during decision-making with peers than parents. Additionally, functional connectivity analyses showed greater coupling between affective, social and cognitive control regions (VS-insula, VS-TPJ) during decision-making with parents than peers. These findings highlight the complex nature of social influence processes in peer and parent contexts, and contribute to our understanding of the opportunities and vulnerabilities associated with adolescent social sensitivity.

Peer-Influence on Risk-Taking in Male Adolescents with Mild to Borderline Intellectual Disabilities and/or Behavior Disorders

This study aimed to disentangle the effects of Mild-to-Borderline Intellectual Disability (MBID) and Behavior Disorders (BD)on risk taking in circumstances where peer influence was absent or present. We studied 319 adolescents in four groups: MBID-only, MBID+BD, BD-only, and typically developing controls. The Balloon Analogue Risk-Task (BART), in a solo or peer condition, was used as a proxy of real-life risk-taking. Results show a significant main effect of BART condition. Post-hoc tests indicated higher risk-taking in the peer compared to the solo condition in all groups except BD-only. Moreover, risk taking was increased in adolescents with MBID compared to adolescents without MBID, but only under peer-influence. No main or interaction effects with BD were observed. Model based decomposition of BART performance in underlying processes showed that the MBID related increase in risk-taking under peer-influence was mainly related to increased risk-taking propensity, and in the MBID-only group also to increased safety estimates and increased confidence in these safety estimates. The present study shows that risk-taking in MBID may be better explained by low intellectual functioning than by comorbid BD, and may not originate in increased risk taking per se, but may rather be related to risk-taking under peer-influence, which is a complex, multifaceted risk-taking context. Therefore, interventions to decrease risk-taking by adolescents with MBID that specifically target peer-influence may be successful.

The effect of active and passive peer encouragement on adolescent risk-taking

INTRODUCTION

In this experiment, we investigated the effect of active (pressure) and passive (imitation) peer encouragement on adolescent risk-taking and assessed gender differences.

METHOD

The participants performed the Balloon Analogue Risk Task (BART) with the same-sex e-confederate. The experiment consisted of a 2 (passive encouragement: no/yes updates about the number of pumps of the e-confederate) by 2 (active encouragement: no/yes messages received from the e-confederate) by 2 (gender: girls/boys) by 3 (time: baseline/first message or update/second message or update) mixed design. The participants comprised 138 Dutch secondary-school students aged 11-19 years old of whom 46% boys. They were assigned to one of the four conditions: 1. neutral (e-confederate present), 2. passive (two updates received), 3. active (two messages received), or 4. combined (two updates and two messages received).

RESULTS

Only a significant main effect of passive peer encouragement and a significant interaction effect of passive peer encouragement*time were shown. The participants exposed to passive peer encouragement took significantly more risk compared to other participants. Moreover, adolescent risk-taking significantly increased after the first and second update compared to baseline (no update).

CONCLUSION

The findings suggest that adolescents are more likely to engage in risk-taking because of passive rather than active peer encouragement. Thus, communication through text-based messages in which young people provide information solely about their own risk-taking may be an important aim of prevention and intervention programs.

Excessive Gambling and Online Gambling Communities

The Internet provides an accessible context for online gambling and gambling-related online communities, such as discussion forums for gamblers. These communities may be particularly attractive to young gamblers who are active Internet users. The aim of this study was to examine the use of gambling-related online communities and their relevance to excessive gambling among 15-25-year-old Finnish Internet users (N = 1200). Excessive gambling was assessed by using the South Oaks Gambling Screen. Respondents were asked in a survey about their use of various kinds of gambling-related online communities, and sociodemographic and behavioral factors were adjusted. The results of the study revealed that over half (54.33%) of respondents who had visited gambling-related online communities were either at-risk gamblers or probable pathological gamblers. Discussion in these communities was mainly based on sharing gambling tips and experiences, and very few respondents said that they related to gambling problems and recovery. In three different regression models, visiting gambling-related online communities was a significant predictor for excessive gambling (with 95% confidence level) even after adjusting confounding factors. The association of visiting such sites was even stronger among probable pathological gamblers than among at-risk gamblers. Health professionals working with young people should be aware of the role of online communities in terms of development and persistence of excessive gambling. Monitoring the use of online gambling communities as well as utilizing recovery-oriented support both offline and online would be important in preventing further problems. Gambling platforms should also include warnings about excessive gambling and provide links to helpful sources.

Parents Versus Peers: Assessing the Impact of Social Agents on Decision Making in Young Adults

Young adulthood is a developmental phase when individuals must navigate a changing social milieu that involves considering how their decisions affect close others such as parents and peers. To date, no empirical work has directly evaluated how young adults weigh these relationships against one another. We conducted a preregistered experiment in which we pitted outcomes for parents against outcomes for friends. Participants ( N = 174, ages 18-30 years) played two runs of the Columbia Card Task-one in which gains benefited a parent and losses were incurred by a friend and another in which the opposite was true. We also tested whether age, relationship quality, and reward type earned for parents and friends (simulated vs. real) acted as moderating influences on parent-friend prioritization. Results showed that individuals were more likely to make decisions that benefited a parent at the expense of a friend. Relationship quality and reward type moderated this effect, whereas age did not.

Information about peer choices shapes human risky decision-making

Humans frequently make choices that involve risk for health and well-being. At the same time, information about others’ choices is omnipresent due to new forms of social media and information technology. However, while past research has shown that peers can exert a strong influence on such risky choices, understanding how information about risky decisions of others affects one’s own risky decisions is still lacking. We therefore developed a behavioral task to measure how information about peer choices affects risky decision-making and call it the social Balloon Analogue Risk Task (sBART). We tested this novel paradigm in a sample of 52 college young adults. Here we show that risky decisions were influenced in the direction of the perceived choices of others – riskier choices of others led to riskier behavior whereas safer choices of others led to less risky behavior. These findings indicate that information about peer choices is sufficient to shape one’s own risky behavior.

Media use and brain development during adolescence

The current generation of adolescents grows up in a media-saturated world. However, it is unclear how media influences the maturational trajectories of brain regions involved in social interactions. Here we review the neural development in adolescence and show how neuroscience can provide a deeper understanding of developmental sensitivities related to adolescents' media use. We argue that adolescents are highly sensitive to acceptance and rejection through social media, and that their heightened emotional sensitivity and protracted development of reflective processing and cognitive control may make them specifically reactive to emotion-arousing media. This review illustrates how neuroscience may help understand the mutual influence of media and peers on adolescents' well-being and opinion formation.

An experimental investigation of the influence of deviant peers on own deviancy: A replication study

OBJECTIVES

This study is a replication of a study examining the causal impact of a brief exposure to deviant peers on own deviant behavior, i.e., Paternoster et al. (Journal of Research in Crime and Delinquency, 50:476-503, 2013). This study retested this design using different monetary incentives and a female deviant peer.

METHODS

A total of 69 university students (61% female) from the Netherlands participated in this laboratory-based study (Mage = 20.64; SD = 2.00) under the façade of a study on individual differences predicting memory recall. Participants could earn up to 10 euros. All participants had the opportunity to cheat to illegitimately earn more money (deviancy). Participants in the experimental condition were exposed to a deviant peer who verbalized her intention to cheat, justified this behavior, and then visibly cheated on the memory recall task.

RESULTS

Although participants in both conditions engaged in some deviancy, the brief exposure to a deviant peer significantly increased the amount of deviancy compared to participants who were not exposed to a deviant peer. These results were consistent after controlling for different demographic and theoretical control variables that predict deviancy.

CONCLUSIONS

Although not identical in magnitude, our results echo those found by Paternoster et al. (2013): Even a brief exposure to a previously unknown deviant peer increases the amount of deviant behavior in young adults. Future research should examine factors predicting the susceptibility to (different types and thresholds of) deviant peer influence.

Neural Correlates of Social Influence on Risk Taking and Substance Use in Adolescents

Purpose of Review

Adolescents often engage in elevated levels of risk taking that gives rise to substance use. Family and peers constitute the primary contextual risk factors for adolescent substance use. This report reviews how families and peers influence adolescent neurocognitive development to inform their risk taking and subsequent substance use.

Recent Findings

Developmental neuroscience using functional magnetic resonance imaging (fMRI) has identified regions of the brain involved in social cognition, cognitive control, and reward processing that are integrally linked to social influence on adolescent risk taking. These neural mechanisms play a role in how peer and family influence (e.g., physical presence, relationship quality, rejection) translates into adolescent substance use.

Summary

Peers and families can independently, and in tandem, contribute to adolescent substance use, for better or for worse. We propose that future work utilize fMRI to investigate the neural mechanisms involved in different aspects of peer and family influence, and how these contexts uniquely and interactively influence adolescent substance use initiation and escalation across development.
