Relationship Between Adolescent Risk Preferences on a Laboratory Task and Behavioral Measures of Risk-Taking

The goal of the study was to assess individual differences among adolescents regarding risk-taking behavior in the laboratory. The second aim was to evaluate whether the laboratory-based risk-taking behavior is associated with other behavioral and psychological measures associated with risk-taking behavior. A total of 82 adolescents with no personal history of psychiatric disorder completed a computerized decision-making task, the Wheel of Fortune. On the basis of the choices made between clearly defined probabilities and real monetary outcomes, this task assesses risk preferences when participants are confronted with potential rewards and losses. The participants also completed a variety of behavioral and psychological measures associated with risk-taking behavior. Performance on the task varied on the basis of probability and anticipated outcomes. In the winning sub-task, participants selected low-probability-high-magnitude reward (high-risk choice) less frequently than high-probability-low-magnitude reward (low-risk choice). In the losing sub-task, participants selected low-probability-high-magnitude loss more often than high-probability-low-magnitude loss. On average, the selection of probabilistic rewards was optimal and similar to performance in adults. There were, however, individual differences in performance, and one-third of the adolescents made high-risk choice more frequently than low-risk choice while selecting a reward. After controlling for sociodemographic and psychological variables, high-risk choice on the winning task predicted "real-world" risk-taking behavior and substance-related problems. These findings highlight individual differences in risk-taking behavior. Regarding validity of the Wheel of Fortune task, the preliminary data suggest that it might be a valuable laboratory tool for studying behavioral and neurobiological processes associated with risk-taking behavior in adolescents.

The Influence of Risk-Taking Behaviors on the Transition Into Marriage: An Examination of the Long-Term Consequences of Adolescent Behavior

Previous studies have examined the consequences of adolescent substance use and delinquency, yet most of these studies have focused on the relatively short-term effects of such behaviors. The present study examines the long-term consequences of adolescent delinquency and substance use as it affects the marital choices of young adults. Using a nationally representative sample of 5,331 females and 4,842 males in their late 20s, the analyses show that both substance use patterns and delinquent behavior in the adolescent years significantly affect the likelihood of marriage and the age at first marriage of young adults. Delinquent behaviors appear to increase the likelihood of marriage and lower the age at first marriage for both sexes, whereas higher levels of substance use (alcohol and marijuana) substantially lower females' likelihood of marriage. The results suggest that a gender difference exists in how risk-taking behaviors in adolescence impacts marital outcomes in adulthood. The analyses are discussed within the framework of precocious development theory.

To Tweet, or Not to Tweet: Gender Differences and Potential Positive and Negative Health Outcomes of Adolescents’ Social Internet Use

Adolescents and young adults are avid Internet users. Online social media, such as social networking sites (e.g., Facebook, MySpace), blogs, status updating sites (e.g., Twitter) and chat rooms, have become integral parts of adolescents' and young adults' lives. Adolescents are even beginning to enter the world of online dating with several websites dedicated to "teenage online dating." This paper reviews recent peer-reviewed literature and national data on 1) adolescents use of online social media, 2) gender differences in online social media and 3) potential positive and negative health outcomes from adolescents' online social media use. We also examine parental monitoring of adolescents' online activities. Given that parental supervision is a key protective factor against adolescent risk-taking behavior, it is reasonable to hypothesize that unmonitored Internet use may place adolescents' at significant risk, such as cyberbullying, unwanted exposure to pornography, and potentially revealing personal information to sexual predators.

Breaking Confidentiality to Report Adolescent Risk-Taking Behavior by School Psychologists

School psychologists often break confidentiality if confronted with risky adolescent behavior. Members of the National Association of School Psychologists (N = 78) responded to a survey containing a vignette describing an adolescent engaging in risky behaviors and rated the degree to which it is ethical to break confidentiality for behaviors of varying frequency, intensity, and duration. Respondents generally found it ethical to break confidentiality when risky adolescent behaviors became more dangerous or potentially harmful, although there was considerable variability between respondents. Significant gender effects were found between male and female respondents for alcohol use, and a significant Form Type (i.e., male or female vignette) × Frequency/Duration interaction was observed for antisocial behaviors. School psychologists could benefit from further training in ethical decision making because these ethical dilemmas are not always clear-cut.

Approche neuroéconomique de la prise de risque à l’adolescence

Risk-taking behaviors represent the main cause of morbi-mortality in adolescence. Here, we analyze their neural correlates, based on a neuroeconomics approach. This approach postulates that risk-taking behaviors result from multiple decision-making biases that impair the selection of the most appropriate action among alternatives based on their subjective evaluation. Specifically, we investigate three important domains in value-based decision-making: risk aversion, loss aversion and intertemporal choice.First, when people have to make a decision between two rewarding options, they will usually prefer the more certain, even possibly lower, option - a phenomenon called "risk aversion". Yet adolescent people have been found to be less averse to risk than adults. This observation was linked to hypoactivation in (1) the anterior insula, involved in negative emotion such as fear and disgust and (2) the anterior cingular and the posterior ventromedial prefrontal cortices, involved in the monitoring of conflict and error detection. Second, people are generally described as being more sensitive to the possibility of losing objects than to that of gaining the same objects - "loss aversion". Here, we suggest that adolescents may be less averse to losses than adults when estimating the prospects of gaining and losing objects. Indeed, adolescent people have been found to be more affected by reward (e.g. euphoria or social integration consecutive to drug absorption) and less affected by punishment (e.g. malaise after drug consumption) than adults. Whereas the former process is subserved by hyperactivations in regions involved in reward evaluation such as the nucleus accumbens, the latter has been proposed to be subserved by hypoactivations in regions involved in negative emotions such as the amygdala or the insular cortex. This lower sensitivity to losses compared to gains in adolescents could be another important mechanism underlying risk-taking behaviors. A third dimension of adolescents' decision-making biases is temporality. It has been shown that adolescents favor immediate over delayed prospects, reflecting how future consequences of their decisions are heavily discounted. For example, adolescents can fail in projecting the future benefits of having safe sex - and thereby avoiding the risk of sexually transmitted disease or pregnancy - being more interested in the immediate reward of having romantic uninterrupted sexual intercourse. This impairment in inhibiting the choice of the early alternative could be related to the hypofunctionality of the lateral prefrontal cortex. Importantly, these three biases in the evaluation of decisions by adolescents may be related to the maturation of two neuronal systems. On the one hand, the early reorganization of dopaminergic neurons in the motivational system, due to the brutal secretion of sex hormones (mostly estrogens, testosterone and oxytocin) at the beginning of puberty, impels adolescents toward thrill seeking. On the other hand, the slow maturation of the cognitive control system, mostly exerted by the prefrontal cortex, implies that these impulses cannot be appropriately regulated.Two important neurodevelopmental mechanisms are thought to play a key role in the genesis of risk-taking behaviors in adolescence: the brutal secretion of sex hormones at the beginning of puberty and the delayed maturation of cognitive control. As such, these behaviors can be considered as inevitable, even if other factors, like sex, heredity and precariousness, can enhance their frequency. The implications of these conclusions for the prevention of risk-taking behaviors in adolescence are discussed.

Movie Character Smoking and Adolescent Smoking: Who Matters More, Good Guys or Bad Guys?

To assess the association between smoking onset and exposure to movie smoking according to character type. A longitudinal, random-digit-dial telephone survey of 6522 US adolescents was performed with movie exposure assessed at 4 time points over 24 months. Adolescents were asked whether they had seen a random subsample of recently released movies, for which we identified smoking by major characters and type of portrayal (divided into negative, positive, and mixed/neutral categories). Multivariate hazard regression analysis was used to assess the independent effects of these exposures on the odds of trying smoking. By the 24-month follow-up survey, 15.9% of baseline never-smokers had tried smoking. Within the sample of movies, 3848 major characters were identified, of whom 69% were male. Smokers represented 22.8% of 518 negative characters, 13.7% of 2486 positive characters, and 21.1% of 844 mixed/neutral characters. Analysis of the crude relationship showed that episodes of negative character smoking exposure had the strongest influence on smoking initiation. However, because most characters were portrayed as positive, exposure to this category was greatest. When the full population effect of each exposure was modeled, each type of character smoking independently affected smoking onset. There was an interaction between negative character smoking and sensation-seeking with stronger response for adolescents lower in sensation-seeking. Character smoking predicts adolescent smoking initiation regardless of character type, which demonstrates the importance of limiting exposure to all movie smoking. Negative character portrayals of smoking have stronger impact on low risk-taking adolescents, undercutting the argument that greater exposure is a marker for adolescent risk-taking behavior.

Functional Brain Imaging of Development-Related Risk and Vulnerability for Substance Use in Adolescents

The adolescent period is characterized by substantial behavioral changes, including increases in novelty-seeking and risk-taking, which may facilitate substance use and experimentation. These behavioral changes co-occur with widespread structural and functional neural developments. Ontogenic changes affecting the neural circuitry subserving inhibitory control and reward-related processes are particularly relevant to adolescent risk-taking behavior. Impairment or immaturity of these processes are shown to contribute to enhanced risk for substance abuse. Additionally, the direct neural action of drugs of abuse in adolescents may have more severe consequences than in adults because of the additional potential effects on development. Functional neuroimaging research is beginning to examine the neural correlates of reward and inhibitory processes in adolescents. However, the study of the consequences of exposure to drugs of abuse on brain function in adolescents is lagging. This review summarizes the functional neuroimaging literature that can inform conceptualizations of risk and consequences of substance use in adolescence.

What Motivates the Adolescent? Brain Regions Mediating Reward Sensitivity across Adolescence

The relation between brain development across adolescence and adolescent risky behavior has attracted increasing interest in recent years. It has been proposed that adolescents are hypersensitive to reward because of an imbalance in the developmental pattern followed by the striatum and prefrontal cortex. To date, it is unclear if adolescents engage in risky behavior because they overestimate potential rewards or respond more to received rewards and whether these effects occur in the absence of decisions. In this study, we used a functional magnetic resonance imaging paradigm that allowed us to dissociate effects of the anticipation, receipt, and omission of reward in 10- to 12-year-old, 14- to 15-year-old, and 18- to 23-year-old participants. We show that in anticipation of uncertain outcomes, the anterior insula is more active in adolescents compared with young adults and that the ventral striatum shows a reward-related peak in middle adolescence, whereas young adults show orbitofrontal cortex activation to omitted reward. These regions show distinct developmental trajectories. This study supports the hypothesis that adolescents are hypersensitive to reward and adds to the current literature in demonstrating that neural activation differs in adolescents even for small rewards in the absence of choice. These findings may have important implications for understanding adolescent risk-taking behavior.

Pathways to Adult Sexual Revictimization

The purpose of this study is to investigate direct and indirect social and behavioral risk factors for adult sexual revictimization. Participants include 147 adult, predominantly African American (88%) women, 59% of whom had a documented history of child sexual abuse. Participants are interviewed in adulthood about adolescent and adult sexual victimization as well as other background and lifestyle characteristics. Structural equation modeling indicates that the relationship between child and adolescent sexual victimization is indirect, mediated by adolescent risk-taking behavior. The relationship between adolescent and adult sexual victimization is also indirect, mediated by risky sexual behavior. The residual effects of early childhood family environment and childhood physical abuse also indirectly predict sexual revictimization. Results provide empirical support for the general supposition that the relationship between child and adult sexual victimization is complex and that many intermediary factors differentially affect risk for a heightened vulnerability to sexual revictimization.

Estradiol, testosterone, differential association and aggressive and non-aggressive risk-taking in adolescent girls

Although the relation between androgens and adolescent risk-taking has been relatively well documented in boys, little is known as to how sex steroid hormones relate to aggressive (ART) and/or non-aggressive adolescent risk-taking (NART) behavior in girls. On the basis of a sample of 298 adolescent girls (mean age: 14.3 years), we examined: (i) the relationship between serum levels of testosterone (T) and estradiol (E2) in relation to ART and NART and (ii) if differential association--having friends who are highly involved in risk-taking--moderates the relationship between relationships between hormones and risk-taking. The sample provided evidence of an association between free estradiol (FE2) and both NART (Beta=0.19; p<0.01) and ART (Beta=0.19; p<0.01), controlling for age and pubertal development. No relationship between T and ART or NART was found. The importance of the relationship between E2 and ART and NART differed between girls at different phases of their menstrual cycle and was significant only for girls in the mid-phase of the menstrual cycle. In addition, significant interactions between differential association and FE2 were found indicating that the relationship between FE2 and NART and ART was particularly strong in girls with high levels of differential association.

Learning Disabilities and Risk-Taking Behavior in Adolescents

Risk-taking behavior includes alcohol and drug use, delinquency, acts of aggression, sexual activity, and so on. Many studies have explored the relationship between adolescents and risk-taking behavior; however, only a few studies have examined this link in adolescents with learning disabilities (LD) or attention-deficit/hyperactivity disorder (ADHD). The purpose of the present study was to address that limitation by comparing the risk-taking behavior of adolescents with LD (n = 230), with comorbid LD/ADHD (n = 92), and without LD or ADHD (n = 322) on their substance use, engagement in major and minor delinquency, acts of aggression, sexual activity, and gambling activities. The study also investigated whether psychosocial variables (e.g., well-being) may act as mediating variables that help explain between-group differences. Results suggest that it is a combination of the LD and the secondary psychosocial characteristics that explains why adolescents with LD and comorbid LD/ADHD more frequently engage in some risk-taking behavior.

Mechanisms underlying heightened risk taking in adolescents as compared with adults

Self-report surveys and behavioral tasks indicate greater risk-taking behavior in adolescents as compared with adults. However, the underlying causes of these behavioral differences remain unclear. The present study examined the possibility that adolescents may be more susceptible to immediate positive and negative outcomes than adults. We compared the behavior of adolescents and adults on a modified version of the Balloon Analogue Risk Task (Lejuez et al., 2002). The task required that participants press a button to "inflate" a series of balloons on a computer screen. Balloons inflated until either the participant released the button ("saved" balloons) or the balloon "burst." Accumulated points increased as the duration of the buttonpress increased; however, simultaneously, the likelihood that the balloon would burst also increased. Adolescents inflated balloons to a larger size prior to saving them than adults did, suggesting relatively higher levels of risk taking, although the adolescents' behavior was not uniformly risk prone. Further, in comparison with adults, behavior in adolescents was more influenced by whether a balloon was saved or had burst on the preceding trial, suggesting that sensitivity to immediate consequences is one mechanism that underlies the observed difference in risk taking.

Student Risk-Taking Behaviors: When Do School Counselors Break Confidentiality?

A total of 204 middle and high school counselors from across the United States responded to a survey in which they were asked to determine whether they view specific adolescent risk-taking behaviors of varying intensity, frequency, and duration as warranting parental notification. Results suggest that counselors’ perceptions that it is ethical to break confidentiality and report the risk-taking behaviors increased when the behaviors were more intense, more frequent, and of longer duration. Further, although there was less ambiguity regarding the perceived dangerousness of some behaviors (e.g., suicidal ideation), all behaviors showed some variance or disagreement among respondents with regard to their willingness to break confidentiality. Implications and suggestions for school counselors are considered.

Developmental changes and individual differences in risk and perspective taking in adolescence

Despite the assumed prevalence of risk-taking behavior in adolescence, the laboratory evidence of risk taking remains scarce, and the individual variation poorly understood. Drawing from neuroscience studies, we tested whether risk and reward orientation are influenced by the perspective that adolescents take when making risky decisions. Perspective taking was manipulated by cuing participants prior to each choice whether the decision was made for "self," or from the perspective of an "other" (the experimenter in Experiment 1; a hypothetical peer in Experiment 2). In Experiment 1, we show a developmental decrease in risk-taking behavior across different stages of adolescence. In addition, all age groups made fewer risky choices for the experimenter, but the difference between self and other was larger in early adolescence. In Experiment 2, we show that high sensation-seeking (SS) adolescents make more risky choices than low SS adolescents, but both groups make a similar differentiation for other individuals (low risk-taking or high risk-taking peers). Together, the results show that younger adolescents and high SS adolescents make more risky choices for themselves, but can appreciate that others may make fewer risky choices. The developmental change toward more rational decisions versus emotional, impulsive decisions may reflect, in part, more efficient integration of others' perspectives into one's decision making. These developmental results are discussed regarding brain systems important for risk taking and perspective taking.

La pratique du parkour chez les adolescents des banlieues : entre recherche de sensation et renforcement narcissique

Objective The aim of the study was to explore the relationships between sensation seeking, narcissistic personality and risk-taking behaviors in adolescents. Subjects and method The population includes 92 participants divided in 2 groups depending on the physical activity practiced; at risk (Free Running: group 1, sex-ratio 11G/36B; M age=14.43 years; S.D.=1.44) or not at risk (Gymnastic: Group 2, sex-ratio 15G/30B; M age=14.18 years; S.D.=1.6). We assessed sensation seeking with the Sensation Seeking Scale, and narcissism with the Narcissistic Personality Inventory. Results Adolescents who practiced a risk-taking sport need more sensation than the ones who do not practice a risk-taking sport. They also have a more narcissistic personality and particularly express more leadership and authority. The same relation is observed when comparing boys to girls. Conclusion The practicing of free running by adolescents of the suburbs reflects a need for sensation and leadership, but does not seem to be linked to maladaptive or psychopathologic behaviors.

The utility of personality variables and behaviorally-based measures in the prediction of risk-taking behavior

The five-factor personality model has demonstrated effectiveness in the prediction of adolescent risk-taking behavior (Gullone, & Moore, 2000). The Bechara Gambling Task (BGT; Bechara, Damasio, Damasio, & Anderson, 1994) and the Balloon Analogue Risk Task (BART; Lejuez et al., 2002) are two behaviorally-based measures that have also demonstrated some effectiveness in the prediction of risk-taking (Bechara, 2003; Lejuez, Aklin, Zvolensky, & Pedulla, 2003). The current study compares self-report and behaviorally-based measures in the prediction of risk-taking behavior in a college based sample. Zero-order correlations revealed several relationships among measures, and regression models indicated behaviorally-based measures explained significant variance beyond personality measures for subsets of risky behaviors. The utility of the BART and the BGT in the prediction of risk-taking is explored.

Incentive‐related modulation of cognitive control in healthy, anxious, and depressed adolescents: development and psychopathology related differences

Developmental changes in cognitive and affective processes contribute to adolescent risk-taking behavior, emotional intensification, and psychopathology. The current study examined adolescent development of cognitive control processes and their modulation by incentive, in health and psychopathology. Predictions include 1) better cognitive control in adults than adolescents, and in healthy adolescents than anxious and depressed adolescents, and 2) a stronger influence of incentives in adolescents than adults, and in healthy adolescents than their depressed and anxious counterparts. Antisaccadic eye movement parameters, which provide a measure of cognitive control, were collected during a reward antisaccade task that included parameterized incentive levels. Participants were 20 healthy adults, 30 healthy adolescents, 16 adolescents with an anxiety disorder, and 11 adolescents with major depression. Performance accuracy and saccade latency were analyzed to test both developmental and psychopathology hypotheses. Development and psychopathology group differences in cognitive control were found. Specifically, adults performed better than healthy adolescents, and healthy adolescents than anxious and depressed adolescents. Incentive improved accuracy for all groups; however, incremental increases were not sufficiently large to further modulate performance. Incentives also affected saccade latencies, pushing healthy adolescent latencies to adult levels, while being less effective in adolescents with depression or anxiety. This latter effect was partially mediated by anxiety symptom severity. Current findings evidence the modulation of cognitive control processes by incentives. While seen in both healthy adults and healthy adolescents, this modulatory effect was stronger in youth. While anxious and depressed adolescents exhibited improved cognitive control under incentives, this effect was smaller than that in healthy adolescents. These findings suggest differential incentive and/or cognitive control processing in anxiety and depression, and across development. Differences could result from disorder specific, or combined developmental and pathological mechanisms.

Risk‐taking and the adolescent brain: who is at risk?

Relative to other ages, adolescence is described as a period of increased impulsive and risk-taking behavior that can lead to fatal outcomes (suicide, substance abuse, HIV, accidents, etc.). This study was designed to examine neural correlates of risk-taking behavior in adolescents, relative to children and adults, in order to predict who may be at greatest risk. Activity in reward-related neural circuitry in anticipation of a large monetary reward was measured with functional magnetic resonance imaging, and anonymous self-report ratings of risky behavior, anticipation of risk and impulsivity were acquired in individuals between the ages of 7 and 29 years. There was a positive association between accumbens activity and the likelihood of engaging in risky behavior across development. This activity also varied as a function of individuals' ratings of anticipated positive or negative consequences of such behavior. Impulsivity ratings were not associated with accumbens activity, but rather with age. These findings suggest that during adolescence, some individuals may be especially prone to engage in risky behaviors due to developmental changes in concert with variability in a given individual's predisposition to engage in risky behavior, rather than to simple changes in impulsivity.

Earlier Development of the Accumbens Relative to Orbitofrontal Cortex Might Underlie Risk-Taking Behavior in Adolescents

Adolescence has been characterized by risk-taking behaviors that can lead to fatal outcomes. This study examined the neurobiological development of neural systems implicated in reward-seeking behaviors. Thirty-seven participants (7-29 years of age) were scanned using event-related functional magnetic resonance imaging and a paradigm that parametrically manipulated reward values. The results show exaggerated accumbens activity, relative to prefrontal activity in adolescents, compared with children and adults, which appeared to be driven by different time courses of development for these regions. Accumbens activity in adolescents looked like that of adults in both extent of activity and sensitivity to reward values, although the magnitude of activity was exaggerated. In contrast, the extent of orbital frontal cortex activity in adolescents looked more like that of children than adults, with less focal patterns of activity. These findings suggest that maturing subcortical systems become disproportionately activated relative to later maturing top-down control systems, biasing the adolescent's action toward immediate over long-term gains.
