Transactional Linkages Between Parenting Behaviors and Child Executive Functions and Self-Regulation from Early Childhood to Adolescence.

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.

The mediating role of child delay of gratification in the link between early and prolonged poverty exposure and adolescent allostatic load.

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.

Predicting cigarette use initiation and dependence in adolescence using an affect-driven exploration model.

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.

Cascades From Early Adolescent Impulsivity to Late Adolescent Antisocial Personality Disorder and Alcohol Use Disorder.

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.

Parenting Behaviors and Family Conflict as Predictors of Adolescent Sleep and Bedtime Media Use.

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.

Selection versus socialization effects of peer norms on adolescent cigarette use.

Adolescent smokers tend to have friends who also smoke. This association has been attributed to peer socialization and peer selection effects. However, evidence regarding timing and relative magnitude of these effects is mixed. Using a random-intercept cross-lagged panel model, we examined the reciprocal relations between adolescent cigarette use and perceptions of friends' cigarette use in a sample of 387 adolescents, assessed annually for 4 years. Adolescent cigarette use predicted increases in perceived friend use before the reverse effect emerged. Further, some of the effect of early adolescent cigarette use on subsequent use was mediated by changes in perceived friend use. The results support a greater role for friend selection than socialization in predicting early adolescent cigarette use.

Bedtime media use and sleep: evidence for bidirectional effects and associations with attention control in adolescents.

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.

Childhood Adversity, Impulsivity, and HIV Knowledge as Predictors of Sexual Risk Outcomes in At-Risk Female Youth.

Sexual risk behavior in adolescence can lead to adverse health consequences, particularly for female youth. Most interventions focus on imparting knowledge about the consequences of such behaviors, even though little research has examined whether increasing such knowledge results in desired behavioral changes. Further, individual factors such as impulsivity and childhood adversity might moderate this relationship. We examined associations between HIV knowledge and sexual risk behavior and condom use efficacy in a sample of 122 at-risk females, aged 13-18. HIV knowledge was unrelated to sexual risk behavior, but positively related to condom use efficacy. Impulsivity and childhood adversity had direct effects, with no interaction effects. Increasing HIV knowledge may play an important role in promoting proximal predictors of safer sex practices.

Adolescent measures of family socioeconomic status: Reliability, validity, and effects on substance use behaviors in adolescence and young adulthood.

Socioeconomic status (SES) is a robust predictor of health disparities in adolescence and early adulthood, yet obtaining accurate and reliable measurements of family SES from younger participants remains a challenge. We evaluated the reliability and validity of a subjective SES measure, i.e., perceived family financial security (PFS), which assesses adolescents' perceptions of whether their family has enough money to meet their needs. We also examined the predictive associations of PFS and parental education (adolescent reports) with alcohol, marijuana, and tobacco use during adolescence and young adulthood. Longitudinal data were obtained from 593 parent-child dyads in the Pacific Northwest region of the United States, who were assessed eight times between 2005 and 2014. Present analyses included data from four annual assessments conducted when the participating children were adolescents (age range = 10.25-16.33 years) and a final follow-up in young adulthood (age range = 20-23.42 years). PFS had good test-retest reliability and convergent validity with other parent and adolescent reported SES measures. Adolescent-reported PFS significantly predicted tobacco use frequency in young adulthood, whereas adolescent-reported parental education predicted alcohol use frequency. PFS was not a significant predictor of alcohol or marijuana use. Findings suggest that PFS can be a psychometrically sound measure to assess a unique dimension of SES in adolescent samples, with differential predictive associations among substance use outcomes in young adulthood compared to more traditional measures like parental education. Future research should evaluate the psychometric properties and utility of PFS as a complementary SES measure.

Working Memory Development and Motor Vehicle Crashes in Young Drivers.

Importance: Adolescent drivers have the highest rate of motor vehicle crashes, and among equally novice drivers, crash risk is inversely age graded. Working memory (WM), crucial to driving hazard awareness, is also age graded, with ongoing development into late adolescence. Variability in WM capacity and growth trajectory positions WM as a candidate crash risk factor for study, clinical screening, and possible preventative intervention. Objective: To test the association between crashes and differential WM development. Design, Setting, and Participants: This prospective cohort study used data from a longitudinal cohort of 118 community youth in Philadelphia, Pennsylvania. Working memory and other risk factors were measured annually from age 11 to 13 years (prelicensure, in 2005) to 14 to 16 years (in 2009), and again at 18 to 20 years (in 2013). In 2015, a follow-up survey of driving experience identified 84 participants who had started driving. Latent growth curve modeling was used to examine the association between variability in the baseline (intercept) and developmental trajectory (slope) of WM and the crash outcome. Main Outcomes and Measures: Self-reported crashes were the primary outcome. Variability in the relative growth of WM development along with traits and behaviors associated with risky driving were assessed. Results: Of 84 participants (39 [46%] male; mean [SD] age, 20.46 [1.09] years), 25 (29.8%) reported they had been involved in at least 1 crash. Controlling for other crash risk factors, the model indicated that variation in the linear slope of WM growth was inversely associated with reporting a crash (b = -6.41; SE = 2.64; P = .02). Crashes were also associated with reckless driving behavior (b = 0.40; SE = 0.18; P = .03). Variation in the intercept of WM was not associated with crashes (b = -0.245; SE = 0.67; P = .72). Conclusions and Relevance: The results suggest that a relatively slower WM growth trajectory is associated with young driver crashes. Routine assessment of WM across adolescence may help to identify at-risk teen drivers and opportunities for providing adaptive interventions (eg, driving aids or training) that can address limitations in WM-related skills that are critical for safe driving.

Sensation Seeking and Impulsivity Can Increase Exposure to Risky Media and Moderate Its Effects on Adolescent Risk Behaviors.

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.

Disentangling longitudinal relations between youth cannabis use, peer cannabis use, and conduct problems: developmental cascading links to cannabis use disorder.

AIMS: To determine whether cannabis use during adolescence can increase risk not only for cannabis use disorder (CUD) but also for conduct problems, potentially mediated by exposure to peers who use cannabis. DESIGN, SETTING, PARTICIPANTS: Longitudinal study analyzing four waves of longitudinal data from 364 racially and socio-economically diverse, urban, US community youth (at baseline: Mage  = 13.51 (0.95); 49.1% female). MEASUREMENTS: Self-reports of cannabis use, conduct problems, proportion of peers using cannabis and CUD criteria at the final wave were analyzed using a method sensitive to changes over development, the random-intercept cross-lagged panel model. FINDINGS: Change in cannabis use did not predict changes in conduct problems or peer cannabis use over time, controlling for gender, race-ethnicity and socio-economic status. Instead, increases in conduct problems predicted increases in cannabis use and ultimately CUD, with some of the effect mediated by increases in the prevalence of peer cannabis use [ß = 0.12, 95% confidence interval (CI) = 0.07, 0.20]. Additionally, affiliation with peers who used cannabis predicted subsequent CUD via increased personal cannabis use (ß = 0.08, 95% CI = 0.04, 0.14). Significant within-person betas for the cross-lagged effects ranged between 0.20 and 0.27. CONCLUSIONS: Cannabis use in adolescence does not appear to lead to greater conduct problems or association with cannabis-using peers apart from pre-existing conduct problems. Instead, adolescents who (1) increasingly affiliate with cannabis-using peers or (2) have increasing levels of conduct problems are more likely to use cannabis, and this cascading chain of events appears to predict cannabis use disorder in emerging adulthood.

Media violence exposure and aggression in adolescents: A risk and resilience perspective.

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.

Modeling Trajectories of Sensation Seeking and Impulsivity Dimensions from Early to Late Adolescence: Universal Trends or Distinct Sub-groups?

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.

How Patterns of Learning About Sexual Information Among Adolescents Are Related to Sexual Behaviors.

CONTEXT: Parents, peers and media are informal sources of sexual information for adolescents. Although the content of sexual information communicated by these sources is known to vary, little is known about what adolescents report actually learning from each source. METHODS: Data from 1,990 U.S.14-17-year-olds who participated in an online survey in 2015 were used to assess learning about four topics (sex, condoms, hormonal birth control and romantic relationships) from three informal sources (parents, peers, and television and movies). Gender and race differences in learning by source and topic were assessed using t tests. Following a factor analysis, learning about all topics was grouped by source, and regression analyses were conducted to examine associations between learning from each source and three outcomes: sexual activity, condom use and hormonal birth control use. Models included interactions between information sources and race and gender. RESULTS: White adolescents reported learning more from parents and less from media than black adolescents. Compared with males, females learned more about hormonal birth control and less about condoms from their parents, and more about relationships from peers and media. Learning from parents and from peers were positively associated with adolescents' sexual activity (unstandardized coefficients, 0.26 and 0.52, respectively). Learning from parents was positively associated with condom use (odds ratio, 1.5). CONCLUSION: Adolescents' learning about sex from informal sources varies by race and gender. Future research should examine whether sexual health interventions and message development can capitalize on these differences.

Developmental associations between bilingual experience and inhibitory control trajectories in Head Start children.

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.

Do you see what I see? A character analysis of health risk behaviors in television shows popular with Black adolescents in the US.

Adolescents spend many hours per day watching television, and there are racial differences in time spent watching television and in show preferences. Prior research suggests there are also differential associations in how exposure to media content affects adolescent behavior. This study examines the demographic representation of main characters and health risk behaviors (i.e., sex, alcohol use, violence, bullying, and their combinations) portrayed in television content popular with Black and non-Black adolescents. A content analysis of television show characters (n=377) from the 2014-15 season was conducted on shows popular with 14-17 year old adolescent audiences in the United States. Group popularity was determined by Nielsen ratings segmented by Black and non-Black (primarily White) adolescents. Results suggest that character representation varies by whether shows were popular with Blacks or others, and that risk portrayals are common in all popular content with few group differences. Implications for adolescent behavior are discussed.

Using an adoption-biological family design to examine associations between maternal trauma, maternal depressive symptoms, and child internalizing and externalizing behaviors.

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.

Risky movies, risky behaviors, and ethnic identity among Black adolescents.

PURPOSE: To investigate how exposure to sex, alcohol and violent content in mainstream and Black-oriented movies relates to corresponding adolescent behavior among Black youth from the United States and whether those relationships are moderated by ethnic identity. METHODS: The present study uses survey data from an online sample of 1000 Black adolescents and content analysis ratings on top-grossing 2014 films and 2013/2014 Black-oriented films. Content-specific exposure measures for alcohol, sexual activity, and violence were calculated from self-reported exposure data and content analysis ratings. Regression analyses estimated the associations among exposures to risky health content in mainstream and Black-oriented films and adolescent behaviors as well as moderation by ethnic group identity. RESULTS: Black adolescents were mostly unaffected by exposure to risk portrayals in mainstream films, but exposure to risk in Black-oriented films was related to their behavior in all three domains. Strong group identity strengthened the relationship between exposure to sex in Black-oriented and mainstream films depending on the sexual outcome. CONCLUSION: The type of movie (i.e., mainstream or Black-oriented) through which Black adolescents are exposed to risky health portrayals is important for understanding its relationship to their behavior, and variations by ethnic identity were limited to sex content. Future research should identify the mechanisms through which risk content in Black-oriented films is associated with Black adolescents' risky behaviors to determine how media influence contributes to behavioral disparities among youth.

Differences in the Portrayal of Health Risk Behaviors by Black and White Characters in Popular Films.

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.
