RESUMEN
Inadequate sleep in adolescents has been linked to an increase in screen-based media use, especially at bedtime. Parents can play a critical role in regulating adolescent media use and promoting healthy sleep, yet few studies have evaluated parental effects on these outcomes. This study examined the effects of general and media-specific parenting behaviors and family conflict on adolescent sleep outcomes, both directly and indirectly through bedtime media use. Data were collected from 345 middle-schoolers (Mage = 12.65 ± 0.67 years; 47% female; 59% White) at two time points, six months apart. The findings revealed that parental involvement had a significant positive effect on sleep duration that was mediated by bedtime media use. Family conflict had a direct positive effect on daytime sleepiness. Adolescent sleep interventions could benefit from a parenting component focused on positive involvement and fostering a family climate conducive to sleep.

Media exposure to risky behaviors (e.g., alcohol use, violence) has been associated with adolescent engagement in risk-taking behaviors, but not all adolescents are equally at risk. Here we focus on individual differences in impulsivity and sensation seeking and assess their effects on the relation between media risk exposure and adolescent risk behavior. Survey data from 1990 Black and White US adolescents (mean age = 15.6 ± 1.10 years; 48% female) and content analysis of top-grossing films and popular TV shows were analyzed using linear regression models. High levels of impulsivity and sensation seeking were associated with greater exposure to risky media content, and also operated as moderators, exacerbating the impact of media risk exposure on adolescent risk behaviors. Prevention efforts targeting negative effects of media on adolescent health should prioritize youth with high levels of impulsivity and sensation seeking.

Media violence exposure (MVE) is associated with aggressive outcomes in adolescents. However, based on the differential susceptibility hypothesis, this risk is expected to vary based on the individual's unique risk and protective factors. Using survey data from 1,990 adolescents (Mean age = 15.6 ± 1.10 years; 48% female) and content analysis of U.S. top-grossing films and popular TV shows, we evaluated the effect of MVE in relation to both risk (i.e., family conflict, impulsivity, sensation seeking) and protective factors (i.e., parental monitoring, parental involvement, parental mediation). Relative weights analyses revealed that MVE was one of the strongest predictors of aggression, after impulsivity and family conflict. The cumulative risk score showed a linear and quadratic relation with the likelihood of aggression, with MVE and family conflict having an interactive relation in predicting aggression. Parental monitoring remained a significant protective factor even when all risk factors were accounted for. Targeted preventive interventions that reduce family conflict, promote parental monitoring, and reduce exposure to violent media may be effective in reducing aggressive tendencies and related negative outcomes.

Children from lower socioeconomic (SES) backgrounds tend to be at-risk for executive function (EF) impairments by the time they are in preschool, placing them at an early disadvantage for academic success. The present study examined the potentially protective role of bilingual experience on the development of inhibitory control (IC) in 1146 Head Start preschoolers who were followed for an 18-month period during the transition to kindergarten as part of the longitudinal Family and Child Experiences Survey (FACES) 2009 study. Using three waves of data, we predicted individual variation in developmental trajectories of IC for three groups that differed in bilingual experience-English monolinguals, Spanish-English bilinguals, and a group of children who transitioned from being Spanish monolingual to Spanish-English bilinguals during the course of the study. Compared to their English monolingual peers, bilingual children from Spanish-speaking homes showed higher IC performance at Head Start entry, as well as steeper IC growth over time. Children who were Spanish monolingual at the beginning of Head Start showed the lowest IC performance at baseline. However, their rate of IC growth exceeded that of children who remained English monolingual and did not differ from that of their peers who entered Head Start being bilingual. These results suggest that acquiring bilingualism and continued bilingual experience are associated with more rapid IC development during the transition from preschool to kindergarten in children from lower SES backgrounds.

Developmental imbalance models attribute the rise in risk-taking during adolescence to a universal imbalance between rising reward sensitivity and lagging cognitive control. This study tested predictions of an alternate Lifespan Wisdom Model that distinguishes between exploratory/adaptive (e.g., sensation seeking) and maladaptive (e.g., acting-without-thinking, delay discounting) risk-taking propensities and attributes the latter to a sub-set of youth with weak cognitive control. Latent trajectory modeling of six waves of data from 387 adolescents (52% females; spanning average ages of 11-18 years) revealed distinct sub-groups with heterogeneous trajectory patterns for acting-without-thinking and delay-discounting. Only those trajectory groups with weak cognitive control, characterized as "high-increasing" acting-without thinking and "high-stable" delay discounting were predictive of a maladaptive risk-taking outcome, namely substance use disorder. Sensation seeking demonstrated a universal peak, but high levels of sensation seeking were not associated with weakness in cognitive control and were unrelated to substance use disorder, controlling for impulsivity. The findings suggest that maladaptive risk-taking characterized by weak cognitive control over reward-driven impulses is a phenomenon limited to only a sub-set of youth.

Maternal trauma is a complex risk factor that has been linked to adverse child outcomes, yet the mechanisms underlying this association are not well understood. This study, which included adoptive and biological families, examined the heritable and environmental mechanisms by which maternal trauma and associated depressive symptoms are linked to child internalizing and externalizing behaviors. Path analyses were used to analyze data from 541 adoptive mother-adopted child (AM-AC) dyads and 126 biological mother-biological child (BM-BC) dyads; the two family types were linked through the same biological mother. Rearing mother's trauma was associated with child internalizing and externalizing behaviors in AM-AC and BM-BC dyads, and this association was mediated by rearing mothers' depressive symptoms, with the exception of biological child externalizing behavior, for which biological mother trauma had a direct influence only. Significant associations between maternal trauma and child behavior in dyads that share only environment (i.e., AM-AC dyads) suggest an environmental mechanism of influence for maternal trauma. Significant associations were also observed between maternal depressive symptoms and child internalizing and externalizing behavior in dyads that were only genetically related, with no shared environment (i.e., BM-AC dyads), suggesting a heritable pathway of influence via maternal depressive symptoms.

Adolescent exposure to risk in film has been associated with behavior. We coded Black and White character involvement in sex, violence, alcohol use, and tobacco use, and combinations of those behaviors in popular mainstream and Black-oriented films (film n = 63, character n = 426). Health risk portrayals were common, with the majority of characters portraying at least one. Black characters were more likely than Whites to portray sex and alcohol use, while White characters were more likely to portray violence. Within-segment combinations of sex and alcohol were more prevalent for Black characters, while violence and alcohol were more prevalent for Whites. Throughout a film, Black characters were more likely than White characters to portray sex and alcohol, sex and tobacco, and alcohol and tobacco. Risky behaviors are prevalent, but types portrayed differ between Black and White characters. This may have implications for health disparities in Black and White adolescents.

This study uses longitudinal data from the Norwegian Health Study linked with registry data (n = 13262) and the U.S. National Longitudinal Survey of Youth 1997 (n = 3604) to examine (1) whether adolescent health mediates the well-established relationship between socioeconomic background and successful high school completion, and (2) whether this mediated pathway of influence varies by national context. Adolescents from lower educated and lower income families reported poorer health, which negatively impacted their likelihood of graduating from high school. The partial mediational effect of adolescent health was stronger in the U.S. than in Norway. These results suggest that policies aimed at preventing high school dropout need to address adolescent health, in addition to the unequal opportunities derived from socioeconomic disadvantage.

This study examined the prospective influence of adolescent working memory (WM) on changes in impulsivity and sexual risk taking and assessed whether this relation could be explained by confounding effects of parental influences. Data from 360 community adolescents (Mage = 13.5 ± 0.95 years; 52% female; 56% non-Hispanic White; low-mid socioeconomic status (SES); recruited from Philadelphia area in 2004-2005) were analyzed using structural equation modeling to predict changes in impulsivity and sexual risk taking over a 2-year follow-up, using baseline assessments of WM, parental monitoring, parental involvement, and SES. Stronger WM predicted reduced involvement in sexual risk taking at follow-up, effects channeled through changes in impulsivity dimensions of "acting without thinking" and "inability to delay gratification." Parental variables had a protective influence on adolescent impulsivity and risk involvement, but the effects of WM operated independently of parental influences.
RESUMEN
Despite the commonly held belief that there is a high degree of intergenerational continuity in maltreatment, studies to date suggest a mixed pattern of findings. One reason for the variance in findings may be related to the measurement approach used, which includes a range of self-report and official indicators of maltreatment and both cross-sectional and longitudinal designs. This study attempted to shed light on the phenomenon of intergenerational continuity of maltreatment by examining multiple indicators of perpetration of maltreatment in young adults and multiple risk factors across different levels within an individual's social ecology. The sample included 166 women who had been placed in out-of-home care as adolescents (>85% had a substantiated maltreatment incident) and followed into young adulthood, and included three waves of adolescent data and six waves of young adult data collected across 10 years. The participants were originally recruited during adolescence as part of a randomized controlled trial examining the efficacy of the Treatment Foster Care Oregon intervention. Analyses revealed weak to modest associations among the three indicators of perpetration of maltreatment in young adulthood, that is, official child welfare records, self-reported child welfare system involvement, and self-reported maltreatment (r = .03-.51). Further, different patterns of prediction emerged as a function of the measurement approach. Adolescent delinquency was a significant predictor of subsequent self-reported child welfare contact, and young adult partner risk was a significant predictor of perpetration of maltreatment as indexed by both official child welfare records and self-reported child welfare contact. In addition, women who were originally assigned to the intervention condition reported perpetrating less maltreatment during young adulthood. Implications for measurement and interventions related to reducing the risk for intergenerational transmission of risk are discussed.

Based on an emerging neuroscience model of addiction, this study examines how an imbalance between two neurobehavioral systems (reward motivation and executive control) can distinguish between early adolescent progressive drug use and mere experimentation with drugs. Data from four annual assessments of a community cohort (N = 382) of 11- to 13-year-olds were analyzed to model heterogeneity in patterns of early drug use. Baseline assessments of working memory (an indicator of the functional integrity of the executive control system) and three dimensions of impulsivity (characterizing the balance between reward seeking and executive control systems) were used to predict heterogeneous latent classes of drug use trajectories from early to midadolescence. Findings revealed that an imbalance resulting from weak executive control and heightened reward seeking was predictive of early progression in drug use, while heightened reward seeking balanced by a strong control system was predictive of occasional experimentation only. Implications of these results are discussed in terms of preventive interventions that can target underlying weaknesses in executive control during younger years, and potentially enable at-risk adolescents to exercise greater self-restraint in the context of rewarding drug-related cues.

With many adolescents using the internet to communicate with their peers, online harassment is on the rise among youth. The purpose of this study was to understand how parental monitoring and strategies parents use to regulate children's internet use (i.e., internet restriction) can help reduce online harassment among adolescents. Online survey data were collected from a nationally representative sample of parents and their 12-17 year old adolescents (n = 629; 49 % female). Structural equation modeling was used to test direct and indirect effects of parental monitoring and internet restriction on being a victim of online harassment. Potential mediators included adolescents' frequency of use of social networking websites, time spent on computers outside of school, and internet access in the adolescent's bedroom. Age and gender differences were also explored. Adolescents' reports of parental monitoring and efforts to regulate specific forms of internet use were associated with reduced rates of online harassment. Specifically, the effect of parental monitoring was largely direct and 26 times greater than parental internet restriction. The latter was associated with lower rates of harassment only indirectly by limiting internet access in the adolescent's bedroom. These effects operated similarly for younger and older adolescents and for males and females. Adolescents' perceptions of parental monitoring and awareness can be protective against online harassment. Specific restriction strategies such as regulating internet time and content can also help reduce the risk of online harassment.

BACKGROUND: Hosting non-university guests is common among college students, especially during sports and traditional party weekends. However, the effect of non-university guests - a common social reference group - on host-students' drinking behaviors is not well understood. METHOD: Data was drawn from a cross-sectional survey conducted at a public Midwestern university (N=2,951; Mage=20 years) from 2005-2007. Results: Participants who hosted non-university guests tended to be younger in age, male, of white racial background, members of athletic teams, had younger ages of drinking onset, and were more likely to reside off-campus as compared to non-hosts. Host-students also had significantly elevated risk for engaging in heavy party-related drinking while hosting non-university guests, and were more likely to report similar risky drinking behaviors among other party-attendees. Conclusions: Preliminary evidence from this study suggests that college-based prevention efforts would benefit from specifically targeting students who are more likely to host non-university guests.
RESUMEN
Research on the development of executive functions (EFs) and self-regulation (SR) has focused heavily on the early childhood years, when these abilities first emerge. Less is known in comparison about how these abilities develop through adolescence, and how contextual factors, such as parenting, influence their development in later years. Using longitudinal data from the Study of Early Child Care and Youth Development (SECCYD), we used random intercept cross-lagged panel modeling (RI-CLPM) to examine the bidirectional linkages between three parenting behaviors (i.e., autonomy support, supportive presence, hostility), child EFs (i.e., working memory, inhibitory control) and child SR outcomes, from early childhood to adolescence. Parenting in early childhood was significantly associated with change in child EFs from early to middle childhood, but not from middle childhood to adolescence. Specifically, greater autonomy support in early childhood was associated with stronger child working memory and inhibitory control in middle childhood; greater supportive presence in early childhood was associated with stronger child working memory in middle childhood; and higher rates of hostility in early childhood were associated with weaker child inhibitory skills in middle childhood. Reciprocal effects of child EF and SR on parenting were also observed. Specifically, stronger child inhibitory control in early childhood was associated with less hostility in middle childhood, and stronger child self-regulation in middle childhood was associated with greater supportive presence in adolescence. Accounting for lagged and stability effects, there was significant residual covariance between parenting behaviors and child SR in adolescence, suggesting that parenting continues to be associated with the development of SR skills through adolescence. Understanding reciprocal linkages between parenting and child EF/SR through adolescence is critical in developing targeted parenting interventions beyond early childhood to improve children's outcomes.
RESUMEN
Early and prolonged exposure to poverty disrupts biological processes associated with the body's stress response system, leading to long-term negative health outcomes, including obesity, autoimmune disorders, and cardiovascular disease. Allostatic load (AL), a composite measure of chronic stress on the body, is a robust predictor of subsequent health outcomes. However, developmental research examining the associations of early poverty exposure with AL in adolescence, as well as the underlying mechanisms of influence is limited. Early poverty exposure also impedes healthy development of child self-regulation, which may increase risk for high AL in adolescence, but this mechanistic pathway has not yet been tested. We used data from the national Study of Early Child Care and Youth Development (SECCYD) to examine the longitudinal associations between prolonged poverty exposure in early childhood (0-3 years) and AL in adolescence (age 15). We also tested the mediating role of child delay of gratification, a behavioral measure of self-regulation (at age 54 months), in the potential association between early poverty exposure and adolescent AL. Accounting for model covariates (i.e., child biological sex and race-ethnicity) and individual differences in child delay of gratification, early and prolonged poverty exposure was significantly associated with higher AL at age 15. The indirect effect through child delay of gratification was not significant, but the individual pathways of the indirect effect were significant, and the overall direct association of early poverty exposure with adolescent AL was significant. Our findings show that prolonged exposure to poverty in early childhood (0-3 years) can have significant negative associations with both child delay of gratification (at 54 months) and AL (at age 15). Given that the detrimental impacts of poverty exposure can be detected at an early age, targeted prevention efforts (e.g., anti-poverty programs such as cash assistance programs) may be able to offset some of the risks of early poverty exposure on self-regulation and AL.

National surveys indicate high rates of suicidal ideation in youth, especially among females. Coping skill training programs hold promise as a potential intervention that can help young people better manage stress and not consider suicide as a solution to life's problems. To assess the promise of this strategy, the present research examined which coping strategies (if any) predicted reduction in youth suicidal ideation over a 1-year follow-up, and explored the potential pathways through which their influence was channeled. Two waves of panel data from a nationally representative sample of youth, assessed 1 year apart (N = 710; Mean age = 18 years) were analyzed separately by gender using multiple group path analytic procedures. Four coping strategies, namely problem solving, emotional regulation, support seeking and acceptance were found to predict reduction in suicidal ideation among both males and females. However, the influence of these strategies (at baseline) was channeled through distinct pathways. The effect of emotional regulation (and acceptance) was channeled through its use at follow-up and was mediated by reductions in perceived stress and depressive symptoms, leading to reduction in suicidal ideation. The influence of support seeking was also channeled through its more recent use at follow-up, but directly predicted reduction in suicidal ideation, with no effect on perceived stress or depressive symptoms. The effect of problem solving on suicidal ideation was mediated by reduction in depressive symptoms, but was not channeled through its use at follow-up, suggesting a longer time course for the protective influence of this strategy. Finally, acceptance had a direct risk-enhancing effect on suicidal ideation. Coping strategies commonly used by youth can be effective in reducing suicidal ideation and therefore universal training in the effective use of these strategies should be considered. An understanding of the distinct pathways through which their effect on suicidal ideation is transmitted can better inform the design of youth suicide prevention interventions.

Positive school climates and student drug testing have been separately proposed as strategies to reduce student substance use in high schools. However, the effects of drug testing programs may depend on the favorability of school climates. This study examined the association between school drug testing programs and student substance use in schools with different climates. The analysis was based on a nationally representative sample of 943 high school students (48% female) ranging from 14 to 19 years of age (62% identifying as white, 18% Hispanic, 13% African American, and 7% in other categories). Results showed that both male and female students in schools with positive climates reported lower levels of personal substance use. Drug testing was associated with lower levels of personal substance use in positive school climates, but only for female students. There was no relationship between drug testing and male students' substance use. The results are discussed in terms of the importance of considering school climates before implementing drug-testing programs in high schools.

Adolescent decisions, especially in novel contexts, are often guided by affective evaluations (i.e., feelings associated with a stimulus) rather than knowledge of the risks and probabilities of different outcomes. In this study, we used the affect-driven exploration (ADE) model to illustrate how affective evaluations can play a critical role in driving early use of cigarettes, as well as the adaptive function of the resulting experiential learning in informing future affect and cigarette use. We analyzed five waves of data collected from a large, diverse community sample of adolescents who were followed from early to late adolescence (N = 386; 50.9% female; Baseline age = 11.41 ± 0.88 years) during years 2004-2010 to model trajectories of positive affect and risk perceptions (associated with cigarette use) and examined the associations of these trajectories with their self-reported cigarette use and dependence symptoms. Consistent with the ADE model, early initiators reported higher levels of positive affect at baseline, which we argue may have led them to try cigarettes. Notably, most early initiators reported a decline in positive affect over time, suggesting an experience-based shift in affective evaluations associated with cigarette use. Risk perceptions associated with cigarette use did not emerge as a significant predictor of cigarette use or subsequent dependence. Therefore, for deterring adolescent cigarette use, efforts to influence affect (through graphic warning labels and other media) may be more effective than directly influencing risk perceptions. Despite the affective basis for initiating cigarette use, few adolescents engaged in early use (N = 20) or developed symptoms of dependence (N = 25). Majority of those who engaged in early cigarette use showed a decline in positive affect, with corresponding increase in risk perceptions over time. Some early users may indeed continue to engage in cigarette use, but this is likely driven by the addictive properties of the drug. Overall these findings challenge the popular stereotype of impulsive and emotionally reactive behaviors during adolescence, and suggest a more nuanced interpretation of adolescent risk behavior.
RESUMEN
PURPOSE: The behavioral disinhibition model (BDM) posits that a liability toward impulsivity evident by early adolescence underlies the coemergence of antisocial behavior and alcohol use (i.e., problem behaviors) in early-adolescence to mid-adolescence, but that the subsequent development of these problem behaviors (rather than impulsivity itself) predicts the emergence of antisocial personality disorder (APD) and alcohol use disorder (AUD) in late adolescence. The present study was designed to test these predictions of the BDM from early to late adolescence. METHODS: We used five-year longitudinal self-report data from the Philadelphia Trajectory Study that was collected from 2006-2012. Mediational analyses were performed using the Random Intercept Cross-lagged Panel Model, which enables the detection of within-person predictions of changes in problem behaviors during adolescence. The sample was ethnically and socioeconomically diverse, including 364 urban US community youth (at baseline: Mage = 13.51(.95); 49.1% female). RESULTS: Consistent with the BDM, mediational analyses revealed that changes in early adolescent impulsivity predicted late adolescent APD and AUD criteria, mediated by changes in mid-adolescent alcohol use and conduct problems. DISCUSSION: Interventions targeting impulsivity in early adolescence could potentially halt the cascading chain of events leading to both late adolescent APD and AUD by decelerating growth in antisocial behavior and alcohol use during early-adolescence to mid-adolescence. From mid-adolescence to late-adolescence, the consequences of early impulsivity, especially involvement in antisocial behaviors, become a more relevant predictor of both APD and AUD rather than impulsivity itself.

OBJECTIVE/DESIGN: Bedtime media use has been associated with poor sleep and attention difficulties among adolescents, but much of this research has been cross-sectional, limiting current understanding of directionality of effects. This 2-wave prospective study tested bidirectional effects between bedtime media use and sleep measures, including time in bed, sleep onset latency, and daytime sleepiness, and further examined whether bedtime media use and sleep variables were related to attention control difficulties. SETTING/PARTICIPANTS: Data were collected from 345 middle-schoolers (ages 12-14, 47% female) at baseline (T1) and at 6-month follow-up (T2). MEASUREMENTS: Students self-reported their access to media devices and internet in their bedroom, bedtime media use, sleep, and attention control. Data were analyzed using cross-lagged panel modeling. RESULTS: Greater bedtime media use (at T1) was associated with less time in bed and longer sleep onset latency at T2, controlling for T1 levels of these variables. In the case of sleep effects on bedtime media use, greater daytime sleepiness and less time in bed (at T1) were associated with greater bedtime media use at T2, controlling for T1 levels. Further, greater daytime sleepiness (at T2, controlling for T1 levels) was associated with greater attention control difficulties at T2. CONCLUSIONS: Findings provide evidence for some reciprocal relations between bedtime media use and poor sleep in adolescents. Furthermore, higher daytime sleepiness was linked to greater attention control difficulties.
