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.     

Alcohol Use Among Black and White Adolescents Exploring the Influence of Interracial Friendship,the Racial Composition of Peer Groups,and Communities

Black adolescents use less alcohol, on average, than white adolescents. Prior research has struggled to explain the disparity in alcohol use between blacks and whites but not for a lack of potential mediating mechanisms. The current study draws on differential association theory and two waves of panel data (n = 1,016) to examine the influence of interracial friendship, the racial composition of peer groups, and communities on black–white differences in alcohol use. Findings indicate that (1) the racial composition of peer groups and communities influence changes in alcohol use, and (2) racial segregation contributes to racial disparities in alcohol use while interracial friendship reduces these disparities. Results suggest that the socially conservative values of the African‐American community are a strong deterrent to adolescent drinking, affecting even those adolescents who are themselves white but associate with black youth.     

Exposure to Parent and Peer Alcohol Use and the Risk of Drinking Onset and Escalation Among Adolescents

Although the rate of alcohol use among adolescents has declined, it remains their drug of choice. Parent and peer alcohol use are powerful risk factors for youth alcohol use. However, questions remain about how these factors influence underage drinking. The present study investigates the relationship between exposure to parent or peer alcohol use and two stages of adolescent drinking—onset and escalation—overall and at five age points during adolescence. Participants were 9348 adolescents in Waves I (WI) and II (WII) of the National Longitudinal Study of Adolescent Health, whose parents completed interviews at WI, and who identified themselves as either non-drinkers or experimental drinkers at WI. Reports of WII alcohol use were used to measure onset among WI non-drinkers and escalation among WI experimenters. Risk ratios were calculated to assess the overall impact of exposure to parent or peer alcohol use on onset and escalation, and at five age points (i.e., ≤?13, 14, 15, 16, and ≥?17). Findings show that exposure to either parent or friend alcohol use increased the risk of onset and escalation. Age-based analyses reveal a more nuanced relationship, showing variability in the nature and strength of influence by stage of drinking and by age. This study highlights the relevance of both parent and peer modeling on youth drinking throughout adolescence. Implications in advancing prevention and treatment include parental education about the impact of their own behaviors and the importance of monitoring teens’ friendships.     

Associations Between Victimization and Adolescents' Self‐Reported Responses to Peer Provocation Are Moderated by Peer‐Reported Aggressiveness

Many early adolescents experience peer victimization, but little research has examined how they respond to aggression by peers. Thus, in a large sample of early adolescents (N = 648; M age = 12.96; SD = 0.30; 52.0% female), we examined (1) the associations between peer‐reported victimization and self‐reported responses to peer provocation, and (2) whether these associations were moderated by peer‐reported aggression. In particular, we predicted that the reported use of assertion, a strategy generally viewed as socially skillful, would be associated with less victimization, but only for youth low on peer‐reported aggression. Results were consistent with this hypothesis. Moreover, seeking adult intervention was associated with greater victimization for youth high on peer‐reported aggression. Implications for research and practice are discussed.     

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.     

Family,Peer, and Pubertal Determinants of Dating Involvement Among Adolescents

This study examines the influence of family, peer, and biological contributors to dating involvement among early adolescents (11–14 years of age; n = 244). Further, we assess how parental monitoring may be modified by pubertal maturation and older sibling risky behavior. Data on delinquent peer affiliation, pubertal maturation, parental monitoring, older sibling risky behavior, and dating involvement were gathered through observations and surveys from adolescents, mothers, older siblings, and teachers. Results indicate that lower levels of parental monitoring and higher levels of older sibling risky behavior were related to adolescents' dating involvement through delinquent peer affiliation. Pubertal maturation was directly related to dating involvement for early daters. Findings emphasize the value of examining social and biological factors, in concert, over time.     

Alcohol Use and Popularity: Social Payoffs From Conforming to Peers' Behavior

Although many economic analyses of adolescents have examined the costs of risky behaviors, few have investigated the gains that young people derive from such actions, particularly in terms of social payoffs for complying with peer behavior. This paper studies the relationship between adolescents' use of alcohol (relative to that of their peers) and popularity at school. We use data from the National Longitudinal Study of Adolescent Health, a rich and nationally representative survey with detailed information on social networks. Our findings suggest that adolescents are socially rewarded for conforming to their peers' alcohol use and penalized (to a lesser degree) for increasing their consumption above that of their peers. Male adolescents are rewarded for keeping up with their peers' drinking and for getting drunk. Female adolescents are rewarded for drinking per se, but not necessarily for keeping up with their peers. The results offer new information on peer influence and have implications for substance abuse interventions at school and in the community.     

Evaluating Links Among Shyness,Peer Relations,and Internalizing Problems in Chinese Young Adolescents

This study evaluates a model linking shyness, aspects of peer relations, and internalizing problems among young adolescents in the People's Republic of China. Participants were 547 young adolescents from Shanghai, China (46% boys; M_age = 10.35 years, SD = 0.77 years) who completed peer nominations of shyness, rejection, and victimization, and self‐report measures of loneliness, depression, and friendship support. Analyses demonstrated that peer difficulties (rejection, victimization) mediated the associations between shyness and internalizing problems. However, moderated mediation analyses revealed a protective effect for highly supportive friendships, especially for boys. Findings highlight the importance of considering different types of peer experiences in studies of shy young adolescents and are discussed in terms of importance to theory and intervention in China and elsewhere.     

Neighborhood influences on adolescent cigarette and alcohol use: mediating effects through parent and peer behaviors

The influence of neighborhoods on adolescent behaviors has received increasing research attention. In the present study, we use structural equation models to specify pathways from neighborhoods to adolescent cigarette and alcohol use through parental closeness, parental monitoring, parent substance use, and peer substance use. We use a national sample with 959 adolescents 12 to 14 years of age whose residential addresses were matched with 1990 Census tracts to provide neighborhood characteristics. We found that for adolescent cigarette use low socioeconomic status (SES) neighborhoods were associated with increased parental monitoring, which was further associated with decreased adolescent cigarette use. For adolescent alcohol use, high SES neighborhoods were associated with increased parent drinking, which was further associated with increased adolescent alcohol use. Low SES neighborhoods were associated with increased parental monitoring and increased peer drinking, which were in turn associated with decreased and increased adolescent alcohol use, respectively.     

Implicit and Explicit Peer Evaluation: Associations With Early Adolescents’ Prosociality,Aggression, and Bullying

Implicit and explicit peer evaluations were assessed among 120 early adolescents (56 boys, 64 girls; M age = 11.1 years). Explicit peer evaluations were round‐robin ratings of likeability; implicit peer evaluations were assessed with an approach‐avoidance task, also using a round‐robin design. Prosocial behavior, aggression, and bullying were assessed with a standard peer nominations procedure. Prosocial behavior predicted explicit positive evaluations given and received. Bullying and physical aggression predicted receiving explicit negative evaluations from peers. Implicit negative biases were found for girls but not boys. Relationally aggressive girls and bullying girls showed a negative implicit bias toward their peers. Possible implications for intervention are discussed.     

Where It's At! The Role of Best Friends and Peer Group Members in Young Adults' Alcohol Use

We examined the hypothesis that best friends and members from a broader peer group would not differ in the amount of influence they have on young adults' alcohol consumption and that what counts would be the mere presence of drinking peers in a given context—irrespective of the type of relationship such peers would have with the target young adult. Data were used from a naturalistic observation study that was conducted in a “bar‐lab” among 221 young adults aged 18–25 years. Both hierarchical and multilevel regression analyses showed that group effects (i.e., average group levels of alcohol consumption) explained young adults' drinking. When taking into account these group effects, best friends' alcohol consumption in the bar‐lab was a nonsignificant predictor of young adults' alcohol use—although best friends' questionnaire‐assessed drinking did predict alcohol consumption in the bar‐lab.     

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.     

Examining Discrimination,Ethnic‐Racial Identity Status,and Youth Public Regard Among Black,Latino, and White Adolescents

How positively adolescents believe others feel about their ethnic‐racial group (i.e., public regard) is an important part of their ethnic‐racial identity (ERI), which is likely informed by contextual and individual factors. Using cluster analyses to generate ERI statuses among Black, Latino, and White adolescents (n = 1,378), we found that associations between peer versus adult discrimination and public regard varied across ERI status and ethnic‐racial group. However, among all adolescents, an achieved ERI (i.e., having explored ethnicity‐race and having a clear sense about its personal meaning) buffered the negative association between adult discrimination and public regard, but not between peer discrimination and public regard. Implications for understanding the interplay between contextual and individual factors for public regard are discussed.     

Adolescent Work and Alcohol Use Revisited: Variations by Family Structure

Previous research finds adolescent work hours to be associated with increased alcohol use. Most studies, however, fail to account for possible selection effects that lead youth to both work and substance use. Using data from the first two waves of the National Longitudinal Study of Adolescent Health (N = 12,620), a fixed effects regression method is employed to control for stable between‐person differences neglected by previous studies. Results show little relationship between work hours and alcohol use when controlling for individual heterogeneity. Results reveal variations, however, by family structure, with work hours being negatively associated with alcohol use among those from single‐parent households. Although exhibiting significant main effects, family and peer processes fail to account for differences by family structure.     

Longitudinal Associations Among Religiousness,Delay Discounting,and Substance Use Initiation in Early Adolescence

Prior research indicates that religiousness is related negatively to adolescent health risk behaviors, yet how such protective effects operate is not well understood. This study examined the longitudinal associations among organizational and personal religiousness, delay discounting, and substance use initiation (alcohol, cigarette, and marijuana use). The sample was comprised of 106 early adolescents (10–13 years of age, 52% female) who were not using substances at Time 1. Path analyses suggested that high levels of personal religiousness at Time 1 were related to low levels of substance use at Time 2 (2.4 years later), mediated by low levels of delay discounting. Delay discounting appears to be an important contributor to the protective effect of religiousness on the development of substance use among adolescents.     

Supportive Relationships as a Moderator of the Effects of Parent and Peer Drinking on Adolescent Drinking

The goal of this study was to explore whether supportiveness from a parent or a friend moderated the effects of the supportive person's drinking on the trajectory of adolescent alcohol abuse/dependence symptoms. High‐risk adolescents recruited from shelters and a matched sample of adolescents recruited from the sheltered adolescent's former neighborhood completed assessments at baseline, 6, 12, and 18 months. Measures included the Social Network Interview, assessing the drinking and supportiveness of everyone in the network. The alcohol module of the Diagnostic Interview Schedule for Children was also administered. Hierarchical Linear Modeling identified predictors of the trajectory of alcohol symptoms of the 401 adolescents over 18 months. The results showed that the baseline levels of parental drinking predicted increased symptoms over time only for those with low parental support. In contrast, the baseline level of peer alcohol use predicted increased symptoms over time only for those with high peer support. The pattern of results did not differ for shelter youth compared to neighborhood controls.     

Attitudinal and normative predictors of alcohol use by older adolescents and young adults

A model of alcohol use based on the theory of planned behavior, expectancy theory, and the developmental literature on the influence of parents and peers was examined with 87 eleventh grade students, 105 college freshmen, and 107 college juniors. Specifically, the influence of attitudes about the positive and negative consequences of drinking, perceived parental and peer norms about alcohol consumption, and perceived control over drinking predicted self-reported alcohol use. The results suggest that, during adolescence, decisions to consume alcohol are rational, based on the consideration of the positive consequences of alcohol use and perceptions of control over drinking; however, the negative consequences of alcohol use are discounted. While perceived peer norms predicted alcohol consumption in all three age groups, the influence of perceived parental norms varied such that they predicted alcohol use only among the college juniors. Implications and avenues for future research are discussed.     

Chain reactions in adolescents’ cigarette,alcohol and drug use: similarity through peer influence or the patterning of ties in peer networks?

Similarity in substance use among adolescents and their peers is usually attributed to peer influence or, occasionally, to either peer influence or selection. This paper suggests that similarity is due to both peer influence and selection. For some adolescents, peer influence outside the chain occurs first and selection follows; for others, selection occurs first and peer influence within the chain follows. Whichever occurs first, all adolescents are selected and nearly all are influenced. Peer networks contribute to similarity by providing a pattern of peer ties in which peer influence can flourish. Chain reactions result from the pattern and peer influence.     

Prevalence and patterns of tobacco,alcohol, and drug use among Iranian adolescents: A meta-analysis of 58 studies

Adolescence is the critical age when adopting high-risk and health-threatening behaviors including smoking, drug and alcohol use is at its peak. Accordingly, this meta-analysis aimed to provide comprehensive nationwide estimates of tobacco, alcohol, and drug use among Iranian adolescents; and to compare their habits with other societies.Electronic databases, including PubMed, Medline, Embase, Google scholar and National Persian databases of SID, Magiran, and IranMedex were utilized in identifying relevant articles. The included studies were those having publications of quantitative estimates and standard errors of the prevalence of cigarette and drug use among 14–19-year-old high school students in Iran from 2000 to 2014. Random-effects meta-analyses were done including a total of 80,588 high school students.The most common drugs among adolescents in Iran were hallucinogens [25.3% (95% CI: 23.9–26.8)], sleeping pills and tranquilizers [25% (95% CI: 24–26.1)], hookah [23.1% (95% CI: 22.2–23.9)], opiates [22% (95% CI: 21.3–22.7)] and central nervous system (CNS) stimulants [20.1% (95% CI: 19.1–21.1)]. Furthermore, overall estimates for cigarette smoking, alcohol and chewing tobacco/Pan/Nas in the participants were 16.8% (95% CI: 16.4–17.2), 14.7% (95% CI: 14.2–15.3) and 10.0% (95% CI: 8.7–11.4), respectively. However, there was some heterogeneity in the pattern of drug use across the country (P < 0.01). Additionally, the risk of smoking, drinking and drug use by boys was considerably greater than girls. Moreover, data showed a varying trend of drug use over three studied periods of time.In conclusion, a diverse pattern and trend of tobacco smoking, alcohol drinking and drug use among adolescents in Iran was verified. Therefore, preventive and control measures (i.e. education) provided in schools should be compatible with age groups, with emphasis being laid on pattern of use in different parts of the country.     

Effects of beverage-specific alcohol consumption on drinking behaviors among urban youth

Alcoholic beverage consumption among high school students has shifted from beer to liquor. The current longitudinal study examined the effects of beverage-specific alcohol use on drinking behaviors among urban youth. Data included 731 adolescents who participated in Project Northland Chicago and reported consuming alcohol in 7th grade. Logistic regression tested the effects of beverage-specific use on consequences (e.g., alcohol use in the past month, week, heavy drinking, and ever drunkenness). Compared to wine users, adolescents who reported drinking hard liquor during their last drinking occasion had increased odds of alcohol use during the past month (OR = 1.44; 95% CI = 1.01-2.05), past week (OR = 3.37; 95% CI = 1.39-8.18), and ever drunkenness (OR = 1.56; 95% CI = 1.07-2.29). Use of hard liquor was associated with increased risk of alcohol-related consequences. Early selection of certain alcoholic beverages (e.g., hard liquor) may result in negative health outcomes and problematic alcohol use over time.
