Trajectories of Sexual Risk From Middle Adolescence to Early Adulthood

Developmental trajectories of risky sexual behavior were identified in a multiethnic sample of 1,121 youth drawn from the Children of the National Longitudinal Survey of Youth data set (NLSY79). Group-based trajectory modeling of a composite index of sexual risk taking revealed four sexual risk groups from ages 16 to 22: low risk, decreasing risk, increasing risk, and high risk. The Low Risk group exhibited low levels of risk across the study period. The Decreasing Risk group had high levels of sexual risk in adolescence that declined in early adulthood. The Increasing Risk and High Risk groups showed distinct risk patterns during adolescence but converged in early adulthood. When compared with adolescents in the low-risk group, individuals in the other groups were more likely to be male, had mothers who had an early birth, were less likely to live with both biological parents in early adolescence, had higher risk proneness, and reported more negative peer pressure.     

Light and Heavy Heterosexual Activities of Young Canadian Adolescents: Normative Patterns and Differential Predictors

The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer self‐concept, and problem behaviors were examined. The heterosexual activities of the majority of 12‐ and 13‐year‐old adolescents were largely confined to light activities of hugging, holding hands, and kissing. Heavy activities such as petting and sexual intercourse were reported less often. Using predictor variables from Cycle 1 of the NLSCY when participants were 10‐ and 11‐year‐olds, SEM analyses indicated that puberty and higher peer self‐concept shared significant direct pathways to both light and heavy heterosexuality. Heavy sexual activity, however, was uniquely associated with the risk factors of adolescent problem behaviors. Positive and hostile parenting styles were indirectly associated with light sexual activity through peer self‐concept. Positive and hostile parenting styles were also indirectly associated with heavy sexual activity through both peer‐oriented self‐concept and problem behaviors. Results support differential patterns and predictors of light and heavy sexuality in early adolescence.     

Developmental Precursors of Number of Sexual Partners From Ages 16 to 22

This study examines family and child characteristics, parent and peer relationships, and early adolescent behavior as statistical predictors of trajectories of number of sexual partners from midadolescence through early adulthood using data from 527 participants in the Child Development Project. Early adolescent developmental antecedents accounted for modest variance in number of sexual partners. Latent growth models revealed that African American race, more advanced pubertal development, lower parental monitoring knowledge, association with more deviant peers, and lower grade point average in early adolescence each predicted having more sexual partners at age 16. In addition, non‐African American race, lower child IQ, higher parental monitoring knowledge, and lower early adolescent internalizing problems each was associated with a higher rate of growth in number of sexual partners over time at the ages following 16. Latent growth mixture modeling identified subgroups with distinct trajectories of involvement with sexual partners that were associated with family and child characteristics, parent and peer relationships, and behavior in early adolescence.     

Cultivating Conformists or Raising Rebels? Connecting Parental Control and Autonomy Support to Adolescent Delinquency

This study investigates short‐term and long‐term associations between parenting in early adolescence and delinquency throughout adolescence using data from the National Longitudinal Surveys. Multilevel longitudinal Poisson regressions show that behavioral control, psychological control, and decision‐making autonomy in early adolescence (ages 10–11) are associated with delinquency trajectories throughout adolescence (ages 10–17). Path analyses reveal support for three mediation hypotheses. Parental monitoring (behavioral control) is negatively associated with delinquency in the short term and operates partly through changes in self‐control. Parental pressure (psychological control) shows immediate and long‐lasting associations with delinquency through changes in self‐control and delinquent peer pressures. Decision‐making autonomy is negatively associated with delinquency in the long term, yet may exacerbate delinquency in early adolescence by increasing exposure to delinquent peers.     

Effects of Fathers on Adolescent Daughters’ Frequency of Substance Use and Risky Sexual Behavior

This research: (1) implements a genetically informed design to examine the effects of fathers’ presence–absence and quality of behavior during childhood/adolescence on daughters’ frequency of substance use during adolescence; and (2) tests substance use frequency as mediating the relation between paternal behavior and daughters’ sexual risk taking. Participants were 223 sister dyads from divorced/separated biological families. Sisters’ developmental exposure to socially deviant paternal behavior predicted their frequency of tobacco, alcohol, and cannabis (TAC) use. Older sisters who co‐resided with fathers who were more (vs. less) socially deviant reported more frequent TAC use during adolescence. More frequent TAC use predicted more risky sexual behavior for these daughters. No effects were found for younger sisters, who spent less time living with their fathers.     

Harsh Parenting,Deviant Peers,Adolescent Risky Behavior: Understanding the Meditational Effect of Attitudes and Intentions

Although research supports the influence of parents and peers on adolescent risky behavior, less is known about mechanisms proposed to explain this relation. This study examined the influence of adolescent attitudes and intentions about such behaviors. Prospective, longitudinal data came from rural youth who participated throughout adolescence (n = 451). Observed harsh parenting and relationship with deviant peers was assessed in early adolescence, attitudes and intentions were measured during middle adolescence, and risky behavior was assessed in late adolescence. Results indicated that parenting and deviant peers was related to engagement in tobacco use, alcohol use, and risky sexual behaviors. Moreover, attitudes and intentions mediated this relationship even after parent use and adolescent early involvement in these behaviors were taken into account.     

Adolescent Problem Behavior in Toronto,Canada

The purpose of this study was to evaluate the relative association of unique aspects of social capital at the level of families, schools, and neighborhoods on adolescent self‐reported violence, property crimes, and substance use. Data come from the 2006 Canadian International Youth Survey that asked adolescents between the ages of 12 and 15 in the metropolitan city of Toronto (N = 3, 101) about their problem behavior. Poisson regression models revealed that parental monitoring, school performance, peer approval of illegal activities, and neighborhood social disorder were consistently associated with all three adolescent problem behaviors, net of controls. Results were more mixed for remaining measures of social capital on adolescent problem behavior. Interestingly, neighborhood cohesion was a significant predictor of adolescent substance use, but operated in a direction that was contrary to the proposed hypotheses. These findings highlight the importance of teasing out how different facets of social capital in different environments are linked to adolescent problem behavior.     

Longitudinal Effects of Best‐Friend Communication Against Substance Use for Latino and Non‐Latino White Early Adolescents

Prior research examining peer influences on adolescent alcohol, cigarette, and marijuana use has primarily focused on the positive associations that peer substance use and offers have with adolescent use. Consequently, such research has often emphasized the negative influences of peers. This study, however, operationalizes peer influence through best‐friend communication against substance use and examines whether it indirectly protects against substance use by promoting anti–substance use norms. Structural equation modeling was utilized with longitudinal survey data from 277 Latino and 350 non‐Latino white 6th–8th‐grade‐students. For Latino and non‐Latino white students, best‐friend communication was indirectly related to alcohol and cigarette use through norms. Best‐friend communication also was indirectly related to marijuana use, but only for non‐Latino white students and for male students.     

Peer Group Patterns of Alcohol‐Using Behaviors Among Early Adolescents in Victoria,Australia, and Washington State,United States

The goal of this study was to examine and cross‐nationally compare the peer group patterns of alcohol‐drinking behaviors among cohorts of early adolescents (ages 11–14 years) in Victoria, Australia, and Washington State, United States. Latent transition analysis revealed that after 1 year, transitions congruent with peer influence (whereby non‐drinking adolescents initiated alcohol use in the presence of drinking peers) and reverse peer influence were observed in both states; however, transitions congruent with peer selection (whereby drinking adolescents self‐selected into drinking peer groups) were only observed among Victorian early adolescents. Findings were interpreted to suggest that Australian family and cultural norms that more commonly allow early adolescent alcohol use lead to a higher rate of peer selection.     

Parent Psychological Distress: A Moderator of Behavioral Health Intervention Outcomes among Justice‐Involved Adolescents

We examined whether pre‐existing parent psychological distress moderated juvenile offenders’ substance use, sexual risk, and mental health outcomes in a randomized trial. Forty‐seven parent–adolescent dyads received either Family‐based Affect Management Intervention (FAMI) for adolescent substance use and HIV prevention or adolescent‐only Health Promotion Intervention (HPI). Parents’ self‐reported distress at baseline significantly moderated adolescents’ self‐reported marijuana use and alcohol use but not other outcomes at 3 months postintervention, producing crossover interactions. FAMI outperformed HPI when parents reported high‐level distress, whereas HPI outperformed FAMI when parents reported low‐level distress. This finding that the relative efficacy of interventions depends on the severity of parent psychological distress could inform efforts to match substance‐using, justice‐involved adolescents with the intervention most likely to benefit them.     

Sibling Conflict and Ineffective Parenting as Predictors of Adolescent Boys' Antisocial Behavior and Peer Difficulties: Additive and Interactional Effects

Extensive sibling conflict is predictive of multiple poor adjustment outcomes during adolescence and early adulthood, but the frequency and developmental impact of such conflict may be conditional on ineffective parenting. Thus, sibling conflict may add to or amplify the negative effects of ineffective parenting on adolescent boys' adjustment. Hypotheses in this study were that: (a) multiple informant measures of problematic parent–child relationships and of sibling conflict would form distinct constructs rather than a single negative family process construct, and (b) ineffective parenting, sibling conflict, and their interaction measured at ages 10 to 12 would predict boys' concurrent status and developmental trajectories for antisocial behavior and peer adjustment across a 4‐year span from ages 12 to 16. Confirmatory factor and latent growth modeling analyses were consistent with these hypotheses, demonstrating the important developmental impact of sibling conflict.     

Predictors of self‐reported sexually transmitted diseases among homeless and runaway adolescents

Path analysis was used to investigate factors associated with self‐reported sexually transmitted diseases among 569 homeless and runaway adolescents in four Midwestern states. Youth were interviewed by outreach workers directly on the streets, in shelters, and in drop‐in centers. Results indicated that family abuse was positively related to substance use, affiliation with friends who sold sex, and time on own. Early family abuse indirectly increased the likelihood of self‐reported sexually transmitted diseases through time on own, substance use, friends selling sex, and risky sexual behaviors. Finally, substance use and affiliation with friends who sold sex was positively associated with risky sexual behaviors, which in turn was related to self‐reported sexually transmitted diseases. No significant gender interactions were found for this model.     

Sexual Risk Behavior in Young Adulthood: Broadening the Scope Beyond Early Sexual Initiation

A robust link between early sexual initiation and sexual risk-taking behavior is reported in previous studies. The relationship may not be causal, however, as the effect of common risk factors is often not considered. The current study examined whether early initiation was a key predictor of risky sexual behavior in the 20s and 30s, over and above co-occurring individual and environmental factors. Data were drawn from the Seattle Social Development Project, a longitudinal panel of 808 youth. Early predictors (ages 10 to 15) and sexual risk taking (ages 21 to 24 and 30 to 33) were assessed prospectively. Early sexual initiation (before age 15) was entered into a series of probit regressions that also included family, neighborhood, peer, and individual risk factors. Although a positive bivariate relation between early sexual initiation and sexual risk taking was observed at both ages, the link did not persist when co-occurring risk factors were included. Behavioral disinhibition and antisocial peer influences emerged as the strongest predictors of sexual risk over and above early sexual initiation. These results suggest that early sexual initiation must be considered in the context of common antecedents; public health policy aimed at delaying sexual intercourse alone is unlikely to substantially reduce sexual risk behavior in young adulthood.     

Adolescent sexual behavior—family characteristics,parental involvement,and associated mental disorders

Abstract

Manifold factors connect with adolescent sexual behavior, but studies on their reciprocal associations are scarce. This study seeks to find the ways in which parental involvement, family characteristics, depression, and delinquency are connected to adolescent early/risky sexual behavior, and to what extent they modify each other. A population-based self-report survey of nearly 187,000 adolescents (50.4% girls) was used. The most important of the family variables was living in a two-parent family, which showed the clearest inverse association with early/risky sexual behavior throughout adolescence. Depression and delinquency persisted associated with sexual behavior in the presence of the family variables.     

The Over‐Scheduling Hypothesis Revisited: Intensity of Organized Activity Participation During Adolescence and Young Adult Outcomes

Concern exists that youth who spend a lot of time participating in organized out‐of‐school activities (e.g., sports) are at‐risk for poor developmental outcomes. This concern—called the over‐scheduling hypothesis—has primarily been assessed in terms of adolescent adjustment. This longitudinal study of a nationally representative sample of 1,115 youth (ages 12–18) assessed long‐term relations between intensity of participation during adolescence and adjustment at young adulthood (ages 18–24). Time diaries measured intensity as hours per week of participation. Results showed that, controlling for demographic factors and baseline adjustment, intensity was a significant predictor of positive outcomes (e.g., psychological flourishing, civic engagement, and educational attainment) and unrelated to indicators of problematic adjustment (e.g., psychological distress, substance use, and antisocial behavior) at young adulthood.     

Trajectories of Substance Use: Onset and Adverse Outcomes Among North American Indigenous Adolescents

North American Indigenous communities experience disproportionately high rates of substance use, abuse, and dependence and their accompanying consequences. This study uses group‐based trajectory modeling of past‐year substance use (alcohol, marijuana, and cigarettes) with a longitudinal sample of Indigenous adolescents from the northern Midwest and Canada (spanning ages 10–18 years). The early‐onset trajectory (36.3%) had more adverse psychosocial difficulties at baseline than the mid‐onset group (38.3%); both trajectories were associated with several negative outcomes at the end of the study. The late‐onset trajectory (25.3%) did not initiate substance use until later adolescence and had far better outcomes at the last wave of the study. Timing of onset matters. Prevention efforts should begin in late childhood and continue through mid‐adolescence.     

Time-varying associations between parental closeness,self-esteem,and sexual behavior across adolescence and emerging adulthood

This study applied the time-varying effect model (TVEM) to data from the National Longitudinal Study of Adolescent to Adult Health to explore how self-esteem mediated age-varying associations of closeness to mother and father and their child's sexual behavior through adolescence and emerging adulthood. Paternal closeness is associated with lesser odds of sexual behaviors for both female and male adolescents until age 20, whereas maternal closeness only predicts for female adolescents between ages 13 and 15. Self-esteem mediated the association between mother closeness and multiple partners in male adolescents between ages 14.5 and 16.5. Fathers have an impact on adolescent sexual behavior across adolescence and emerging adulthood, while mothers' roles are more important for female adolescents in early adolescence.     

Substance Use and Early Marriage

Prior work indicates that substance use is related to adolescent marriage. We describe two different processes that may account for this relationship and hypothesize patterns of association that would be consistent or inconsistent with each. Using data from a study that followed west coast youth from 7th grade to young adulthood (N = 3,324), we assessed the effects of cigarette, alcohol, and marijuana use in 7th and 10th grade on the probability of marriage prior to age 20. When gender, race, and SES were controlled, cigarette use in adolescence, but not other substance use, was associated with early marriage. Low educational attainment and early unwed parenthood each uniquely mediated this association. These results suggest that the link between substance use and early marriage reflects a disposition toward risky or unconventional behavior, not the judgment‐impairing effects of drug and alcohol use.     

Religious Social Support Protects against Social Risks for Adolescent Substance Use

We used a social developmental perspective to identify how prominent social contexts influence substance use during adolescence. Longitudinal data were collected annually from 167 parent–adolescent dyads over four years. We investigated whether parent substance use was related to adolescent substance use directly and indirectly via peer substance use and whether these associations were moderated by religious social support. Structural equation modeling (SEM) analysis indicated significant moderated mediation: Greater parent substance use predicted increases in adolescent substance use indirectly via increased peer substance use when adolescent religious social support was low or average, but not high. These results suggest religious social support may protect adolescents against prominent social risks for intergenerational substance use.
