The Impact of Pubertal Timing on Adolescents’ Alcohol Use

The relation between pubertal timing and alcohol use was investigated in a nationally representative sample (N= 4,686) of junior high school students who were followed up 2 years later (N= 3,862). Information regarding pubertal timing and status, sex‐role identification, number of alcohol intoxications, substance use, sexual behavior, friends’ alcohol use, and involvement in other types of problem behaviors was obtained. The results showed that early timing of pubertal development correlated with number of alcohol intoxications and number of units consumed on each occasion, and, to a lesser degree, with the frequency of alcohol use. Moreover, correlations were stronger among males than among females. Substantial parts of the association between pubertal timing and alcohol intoxications were mediated through friends’ problem behavior. Pubertal timing predicted alcohol use at follow‐up, but the effect was mostly due to increased alcohol intoxications at initial testing.     

The Moderating Effects of Pubertal Timing on the Longitudinal Associations Between Parent–Child Relationship Quality and Adolescent Substance Use

This prospective, longitudinal study investigated the moderating role of pubertal timing on reciprocal links between adolescent appraisals of parent–child relationship quality and girls' (N=1,335) and boys' (N=1,203) cigarette and alcohol use across a 12‐month period. Reciprocal effects were found between parent–child relations and on‐time maturing boys and girls' cigarette and alcohol use, after estimating stability in these constructs across time. Parent–child relationship quality was associated with increased alcohol use 12 months later for early maturing girls. Cigarette and alcohol use were associated with increased problems in the parent–child relationship for late maturing girls. No effects were observed for early and late maturing boys in the pathways between parent–child relationship quality and substance use. Pubertal timing moderated the pathway linking parent–child relationship quality with cigarette use 1 year later such that the association was stronger for late maturing girls compared with early and on‐time maturing girls. The findings indicate interplay between the psychosocial aspects of maturation, family relationships, and adolescent substance use and highlight possible gender‐specific influences.     

Concurrent alcohol and cigarette use among school-going adolescents in Korea

BackgroundConrurrent alcohol and tobacco use may increase the risk for substance abuse in adolescents. The aim of this study was to investigate concurrent alcohol and cigarette use and the co-occurrence risks of each substance in school-going adolescents in Korea.MethodsIn a cross-sectional nationally representative survey in 2016, 65,528 students (Mean age = 15.1 years, SE = 0.02) responded to a questionnaire that included measures of substance use and substance use exposure.ResultsIn all, 13.3% of the students were concurrent lifetime smokers and drinkers (19.3% among boys and 6.7% among girls), 25.5% lifetime alcohol users only (24.2% among boys and 26.9% among girls), 3.0% lifetime smokers only (4.7% among boys and 1.1% among girls) and 58.3% never smoked and never used alcohol (52.2% among boys and 47.8% among girls). All measures of more intensive smoking pattern and smoking exposure and more intensive drinking pattern and drinking exposures, respectively, were associated with consistently increased risk of lifetime alcohol use and lifetime smoking, respectively, compared to lifetime never smokers and abstainers. In multinomial logistic regression, compared to students who neither had used alcohol nor tobacco, concurrent lifetime smokers and drinkers were more likely to be male, mixed or boys school, higher school grade, lower paternal and maternal educational level, perceived lower socio-economic status, ever drug user, perceived stress above average, depressive mood, experience of violence victimization, and living in a rural area or medium sized city.ConclusionPrevention and treatment strategies should better incorporate the comorbidity of cigarette smoking and alcohol use in their intervention programmes.     

Peers influence the tobacco and alcohol use of Chinese adolescents

This two-wave longitudinal study examined peer selection and influence pertaining to tobacco and alcohol use by adolescents and their friends in a sample of 854 Chinese adolescents (384 girls: mean age = 13.33 years). Participants nominated friends and self-reported their tobacco and alcohol use at seventh and again at eighth grade. Longitudinal social network analyses revealed evidence of friend influence but not selection over smoking and drinking. Boys increased their levels of smoking at rates greater than that of girls, but no sex moderation of either selection or influence was found. In interpreting these results, it is important to understand the gender norms for Chinese boys and girls and the cultural context of tobacco and alcohol use.     

INTERGENERATIONAL EFFECTS OF WELFARE REFORM: ADOLESCENT DELINQUENT AND RISKY BEHAVIORS

This study investigates effects of welfare reform in the United States on the next generation. Most previous studies of effects of welfare reform on adolescents focused on high‐school dropout of girls or fertility; little is known about how welfare reform has affected other teenage behaviors or boys. We use a difference‐in‐difference‐in‐differences framework to identify gender‐specific effects of welfare reform on skipping school, fighting, damaging property, stealing, hurting others, smoking, alcohol, marijuana, and other illicit drugs. Welfare reform led to increases in delinquent behaviors of boys as well as increases in substance use of boys and girls, with substantially larger effects for boys. (JEL K42, I12, I31, I38)     

Friendship and Alcohol Use in Early Adolescence: A Multilevel Social Network Approach

This study applies multilevel social network analytic techniques to examine processes of homophilic selection and social influence related to alcohol use among friends in early adolescence. Participants included 3,041 Dutch youth (M age =12 years, 49% female) from 120 classrooms in 14 schools. Three waves with 3‐month intervals of friendship nomination data and self‐reports of drinking behavior were collected. Results revealed that within classrooms, friendship nominations tended to be reciprocated and dyadic friendships tended to be embedded within cohesive subgroups (e.g., cliques). Students tended to nominate friends who were the same sex, from a similar ethnic background, and who they previously knew from primary school. Selection processes turned out to play a more significant role than social influence processes in predicting similarity between early adolescent friends' alcohol use. Although friendship dynamics and individual drinking trajectories substantially differed between classrooms, the effects of homophilic selection and social influence did not.     

Parental Problem Drinking and Adolescent Psychosocial Adjustment: The Mediating Role of Adolescent–Parent Communication

This study explored the relations between parental problem drinking, adolescent–parent communication, and adolescent psychosocial adjustment. Surveys were administered to a diverse sample of 683 15–17‐years‐old adolescents in the spring of 2007 and again in the spring of 2008. Results indicated that paternal problem drinking directly predicted substance use (alcohol and drug use) for boys, but not for girls. In contrast, maternal problem drinking directly predicted substance use (drug use) for girls, but not for boys. Adolescent–parent communication also mediated the relationship between parental problem drinking and psychosocial adjustment for girls, but not for boys. These gender differences highlight the need to consider both the gender of the adolescent and the parent when examining parental problem drinking and adolescent adjustment.     

Gender Roles, Externalizing Behaviors, and Substance Use Among Mexican-American Adolescents

A sample of 60 male and 91 female Mexican-American adolescents (age 13-18) were administered measures of positive (i.e., assertive masculinity, affective femininity) and negative (i.e., aggressive masculinity, submissive femininity) gender roles, internalizing and externalizing problem behaviors, peer substance use, and own substance use (alcohol, cigarettes, marijuana). Negative gender roles were significantly correlated with internalizing and externalizing problems for both boys and girls, with aggressive masculinity also predicting peer substance use for both genders. Assertive masculinity significantly predicted lower alcohol use in boys, and this effect was not mediated by internalizing problems, externalizing problems, or peer substance use. Negative gender roles significantly predicted higher alcohol use in girls, but this effect was almost completely mediated by internalizing problems, externalizing problems, and peer substance use. Results are discussed in terms of gender role socialization among Mexican Americans.     

Smoking risk factors and gender differences among Spanish high school students

The objectives of the present study were to analyze the pattern of tobacco use among Spanish adolescents, as well as to determine gender differences in specific risk factors of cigarette use. The study sample was made up of 1,483 boys and 1,358 girls, aged 12-16 (M = 14). Participants were asked to answer an ad-hoc instrument to evaluate the pattern of use, perceived availability, risk of harm, family- and peer-use, engagement in leisure activities, drive for thinness, and self-esteem. Results showed no gender differences in the pattern of use. With regard to risk and protector factors, a predictive analysis showed that peer-related variables were the most determinant for tobacco use both for boys and girls. Some gender differences were also detected: Playing sports was protective for boys only, and listening to music for girls only. Drive for thinness and self-esteem were not related to tobacco use for either boys or girls. These findings help increase our understanding of smoking risk factors in adolescence and to pay special attention to the group of friends when planning prevention programs to reduce risk factors.     

Predicting Well‐Being and Internalizing Symptoms in Late Adolescence From Trajectories of Externalizing Behavior Starting in Infancy

This study aimed to examine the long‐term prediction of well‐being and internalizing symptoms from trajectories of externalizing behavior problems in 921 children from a population‐based sample. We found that a high stable trajectory of externalizing behavior from infancy (age 1.5) to mid‐adolescence (age 14.5) predicted lower scores on life satisfaction and flourishing for both girls and boys (age 18.5). The high stable trajectory also predicted higher levels of depressive symptoms in boys and anxiety symptoms in girls (age 18.5). The findings are noteworthy as they document how a person‐oriented study of externalizing behavior problems starting in infancy can predict well‐being and internalizing in late adolescence. The findings underline the importance of early health promotion and problem intervention efforts.     

Linking Self‐Regulation and Risk Proneness to Risky Sexual Behavior: Pathways through Peer Pressure and Early Substance Use

The linkages between self‐regulation in childhood, risk proneness in early adolescence, and risky sexual behavior in mid‐adolescence were examined in a cohort of children (N=518) from the National Longitudinal Survey of Youth. The possible mediating role of two early adolescent variables (substance use and negative peer pressure) was also examined. Self‐regulation was assessed by maternal report at ages 8–9, and risk proneness, comprising aspects of sensation seeking and decision making, was assessed by adolescent self‐report at ages 12–13. Structural equation models predicting risky sexual behavior at ages 16–17 indicated that self‐regulation operated partly through early adolescent substance use, whereas risk proneness operated through early adolescent substance use and negative peer pressure. The overall model did not differ significantly for boys and girls, although there were gender differences in the strength of particular paths. These long‐term longitudinal results support the importance of early self‐regulation and risk proneness in setting the stage for adolescent sexual risk taking and implicate substance use and negative peer pressure as processes through which risk proneness and poor self‐regulation lead to risky sexual behavior.     

Parental Divorce and Offspring Depressive Symptoms: Dutch Developmental Trends During Early Adolescence

In this study, we investigated if the association between parental divorce and depressive symptoms changes during early adolescence and if developmental patterns are similar for boys and girls. Data were collected in a prospective population cohort of Dutch adolescents (N = 2,149), aged 10 – 15 years. Outcome variables were self‐reported and parent‐reported depressive symptoms. The effects of divorce were adjusted for parental depression. In both self‐reported and parent‐reported data, we found a three‐way interaction of gender, age, and parental divorce, indicating that with increasing age, parental divorce became more strongly associated with depressive symptoms among girls, but not boys. These results suggest that girls with divorced parents are at particularly high risk to develop depressive symptoms during adolescence.     

Internalizing Symptoms,Peer Substance Use,and Substance Use Initiation

This study used longitudinal survey and social network data covering sixth through ninth grades to test whether internalizing symptoms make early adolescents more prone to (1) exposure to and (2) influence by substance‐using peers. Random effects regressions revealed that increases in symptoms were significantly associated with increases in the proportion of friends who used cigarettes, alcohol, and marijuana; some associations weakened across grades. Event history models revealed that the effect of friends' smoking on smoking initiation decreased as internalizing symptoms increased; symptoms did not moderate the effects of friends' alcohol and marijuana use on alcohol and marijuana use initiation. These findings counter the influence hypothesis of the co‐occurrence of internalizing symptoms with substance use and partly support the exposure hypothesis.     

Personal Network Characteristics as Predictors of Change in Obesity Risk Behaviors in Early Adolescence

The potential for peers to influence obesity risk behavior increases in adolescence, yet there are knowledge gaps of how behaviors are modified in response to peers over time. This study examined how personal friendship network characteristics were associated with obesity‐related behaviors from late childhood to early adolescence. Two waves of friendship, physical activity, screen time, and dietary recall data were collected from 11‐ to 13‐year‐old students (99% retention) in Australia (n = 308) over a five‐ to eight‐month period. Regression models identified friendship network characteristics that predicted later health behaviors which varied by gender and behavior type, such as the number of friends positively associated with physical activity intensity (males) and screen time (females). The need for considering context to influence behavior change is discussed.     

Gender,Family Structure,and Adolescents’ Primary Confidants

Using data from the National Longitudinal Survey of Youth 1997 (N = 4,190), this study examined adolescents’ reports of primary confidants. Results showed that nearly 30% of adolescents aged 16 – 18 nominated mothers as primary confidants, 25% nominated romantic partners, and 20% nominated friends. Nominating romantic partners or friends was related to increased risk‐taking behaviors, supporting the attachment notion that shifting primary confidants to peers in adolescence may reflect premature autonomy from parents. Tendencies to prefer romantic partners over parents varied by gender and family structure, which were greater for those from single‐father families and girls from mother‐stepfather families, but less for those from single‐mother families and boys from mother‐stepfather families, compared with their counterparts from two‐biological‐parent families.     

Selection and influence processes in academic achievement—More pronounced for girls?

Friends tend to be similar in their academic achievement. In this study, we investigate whether this similarity results from students selecting friends with similar achievement or from friends influencing students’ achievement. In particular, we argue that selection and influence effects should be stronger among girls than among boys. Using friendship network data on 1273 German secondary school students and stochastic actor-oriented models for the co-evolution of networks and behavior, we find selection effects only among girls, which is in line with our theoretical arguments. By contrast, influence effects contribute to achievement similarity among both boys and girls.     

Understanding types,locations, & perpetrators of peer-to-peer sexual harassment in U.S. middle schools: A focus on sex,racial, and grade differences

This study employed a mixed-method design to examine sexual harassment victimization among American middle school youth (grades 5–8). Students completed a self-report measure of sexual harassment victimization and indicated where sexual harassment occurs in their school. They responded to open-ended questions about the most upsetting incident they experienced and identified characteristics of perpetrators (N = 858). Verbal victimization (e.g., unwanted sexual commentary and homophobic name-calling) was more frequent than physical victimization and sexual assault. The types of sexual harassment experienced and the perpetrators varied by sex, race, and grade level. Sexual harassment occurred most frequently in hallways, followed by classrooms, gym locker rooms, gym class, lunch room, and outside of the school. The most upsetting unwanted incidents included (1) verbal - homophobic language; (2) verbal - sexual commentary and sexual rumor spreading; (3) physical – being touched; (4) pulling down pants; (5) being sexually assaulted; and (6) dismissiveness of victimization. Girls reported other boys as perpetrators; whereas, boys reported their perpetrators as other boys and close friends. For African-American students, perpetrators were identified as older and romantic partners. For White students, perpetrators were reported as same-age peers and friends. Understanding and recognizing what constitutes sexual harassment and where it most commonly occurs among early adolescence is critical to preventing sexual harassment into late adolescence.     

Characterizing Emotional Support Development: From Adolescent Best Friendships to Young Adult Romantic Relationships

This study examined development of emotional support competence within close friendships across adolescence. A sample of 184 adolescents (53% girls, 47% boys; 58% White, 29% Black, 14% other identity groups) participated in seven waves of multimethod assessments with their best friends and romantic partners from age 13 to 24. Latent change score models identified coupled predictions over time from emotional support competence to increasing friendship quality and decreasing support received from friends. Friend-rated emotional support competence in adolescence predicted supportiveness in adult romantic relationships, over and above supportiveness in adolescent romantic relationships. Teen friendships may set the stage for developing emotional support capacities that progress across time and relationships into adulthood.     

Age‐Specific Associations Between Violence Exposure and Past 30‐Day Marijuana and Alcohol Use

Using data from a cohort study of students at risk for high school dropout, we examined associations between violence exposure and past 30‐day alcohol and marijuana use. We used varying‐coefficient regression with person‐level fixed effects to estimate how those associations changed within‐person across ages approximately 14–23. Generally, violence perpetration was most strongly associated with substance use, within‐person. Substance use became increasingly associated with both observed violence and violence perpetration during early/middle adolescence; this increase continued longer into development (age 18+) for alcohol use. Across most of the age range studied here, violence victimization was minimally associated with within‐person changes in substance use. Results indicate age‐specific associations between violence exposure and alcohol and other drug use, which may be useful for informing prevention strategies.     

Risk and Protective Factors for Early Substance Use Initiation: A Longitudinal Study of Mexican‐Origin Youth

Substance use initiation in adolescence is a critical issue, given its association with substance dependency and associated problems in adulthood. However, due to the dearth of fine‐grained longitudinal studies, the factors associated with early initiation are poorly understood, especially in minority youth. The present study examined substance use initiation in a sample of Mexican‐origin youth (n = 674) assessed annually from age 10 to 16. Using discrete‐time survival analyses, we found that initiation escalated rapidly from late childhood to adolescence, and we identified a wide range of factors, from the individual to the cultural level of analysis, that significantly increased or decreased risk for early initiation. These findings have important implications for programs aimed at preventing early substance use by Mexican‐origin youth.
