Racial differences in early adolescent substance use: Child abuse types and family/peer substance use as predictors

This study examined the associations among child abuse types, family/peer substance use, and adolescent substance use, as well as testing whether these associations vary by race. The sample was derived from the Longitudinal Studies of Child Abuse and Neglect (N = 562). Child sexual abuse, family substance use, and peer substance use were associated with a higher likelihood of adolescent substance use. Sexual abuse was more strongly associated with substance use in Black youth than in White youth. Conversely, greater peer substance use had a stronger association with substance use in White youth than in Black youth.

Individual-, peer-, and parent-level substance use-related factors among 9- and 10-year-olds from the ABCD Study: Prevalence rates and sociodemographic differences

BackgroundAlthough a relatively large body of research has identified multiple factors associated with adolescent substance use, less is known about earlier substance-related factors during preadolescence, including curiosity to use substances. The present study examined individual-, peer-, and parent-level domains pertaining to substance use and how these domains vary by sociodemographic subgroups and substance type. MethodsParticipants were 11,864 9- and 10-year-olds from the baseline sample of the Adolescent Brain Cognitive Development (ABCD) Study. Youth-reported measures were curiosity to use substances and perceived peer substance use. Parent-reported measures were availability of and rules about substances. Generalized logistic mixed models (GLMM) were used to compare these measures across alcohol, nicotine, and marijuana and across sociodemographic subgroupings (sex, race/ethnicity, household income, and family history of alcohol problems). GLMM was then used to examine predictors of curiosity to use by substance type. ResultsThe most striking descriptive differences were found between race/ethnicity and income categories (e.g., positive associations between greater income and greater availability of alcohol). In multivariable analyses, greater curiosity to use alcohol was associated with being male, higher household income, perceived peer alcohol use, and easy alcohol availability; greater curiosity to use nicotine was associated with being male, perceived peer cigarette use, easy availability of cigarettes, and no parental rules about cigarette use. ConclusionsThis study identified substance use-related individual-, peer-, and parent-level factors among a diverse, national sample. Findings highlight the importance of considering sociodemographic and substance-specific variability and may help identify risk and protective factors preceding adolescent substance use.

Latent Classes of Substance Use in Young Adults – A Systematic Review

Background: This systematic review provides an overview of studies on latent classes related to the substance use among young adults (18–25 years). Identifying these classes helps to detect high-risk groups, setting a base for selective prevention. Methods: This systematic literature review included peer-reviewed studies (published up to February, 2021) that identified latent classes and investigated predictors of latent classes relating to the use of marijuana, alcohol and/or other substances within samples of young adults. Results: Twenty studies (sample sizes N = 171 to N = 21945) met the inclusion criteria. 14 studies identified ‘low-level engagers’, ‘light alcohol and tobacco use’, ‘heavy alcohol and tobacco use’ and ‘heavy use/polysubstance use’ classes. Four studies differentiated within the ‘heavy/polysubstance’ class and found ‘traditional clubdrugs’, ‘hallucinogens’ and ‘wide-range illicit drugs’ classes. Male gender and white race predicted membership of the ‘heavy use/polysubstance use’ class consistently across studies. Other predictors of polysubstance use that were consistent across studies were peer substance use, depressive symptoms, parental drinking and participating in an honor society. Conclusions: The investigated predictors of class membership provide insight into social settings and characteristics that predict heavy use or polysubstance use. They can contribute to the development of effective prevention interventions by allowing for a more targeted approach.

Suicidal Ideation Among Transgender and Gender Expansive Youth: Mechanisms of Risk.

Suicide is a leading public health concern among transgender and gender expansive adolescents, although little research has examined mechanisms through which gender identity is associated with suicidal ideation. This study examined the indirect effects of peer victimization, dating violence, substance use (SU), SU problems, and depressive symptoms in the relationship between gender identity and suicidal ideation. Secondary data analysis was conducted from a 2018 statewide survey, including 4464 adolescents who identified as male, female, transgender, or gender expansive (n=1116 per gender). The sample was frequency matched on grade, race, geographic region, and free/reduced lunch status. Mediation analyses were performed. Reports of suicidal ideation were highest among transgender (49.29%) and gender expansive (41.31%) adolescents compared with male (10.82%) and female adolescents (19.08%). Using the Karlson, Holm, and Breen approach, 50.45% of the effect of being transgender on suicidal ideation was mediated through peer victimization, dating violence, and depressive symptoms, and 39.29% through SU, SU problems, and depressive symptoms. The mediation through the same pathways for being gender expansive was 46.37% and 39.89%, respectively. Across both models, depressive symptoms predominately accounted for the mediating effect. Transgender and gender expansive youth are at alarming risk for suicidal ideation, which illustrates the critical need for suicide prevention within this population. Programs that promote mental health and work to prevent bullying, dating violence, SU, and SU problems are crucial; although longitudinal research is needed, targeting these mechanisms may play a critical role in reducing suicidal ideation and risk.

Psychosocial functioning in adolescents growing up with chronic disease: The Dutch HBSC study

Many adolescents worldwide (indirectly) grow up with a chronic disease, which may impact their functioning and wellbeing. The objective of this study is to assess whether adolescents with a (family member with a) chronic disease differ from their healthy counterparts in terms of psychosocial functioning. Data from the Dutch 2013 HBSC-survey were used, including 7168 adolescents (Meanage = 13.7, SD = 1.57, 50.5% female). Participants indicated whether they or one of their family members had a long-term (> 3 months) disease or disability (mental/physical) and were categorized into four groups based on disease presence (none, other, self, both). Psychosocial functioning was assessed in terms of life satisfaction, self-rated health, psychosomatic health, mental health problems, support, substance use, physical exercise, screen time, and school liking. Chronically diseased adolescents (n = 162) reported lower life satisfaction, self-rated and psychosomatic health, more mental health problems, lower peer support, more substance use, and less physical exercise compared to healthy peers. Chronically diseased adolescents who also had a family member with a chronic disease (n = 74) showed comparable outcomes on these life domains, although they did not differ from their healthy peers regarding peer support, substance use, and physical activity. Healthy adolescents with a chronically diseased family member (n = 737) reported significantly lower life satisfaction, self-rated and psychosomatic health, more mental health problems, and less family support compared to healthy peers who grew up in healthy families; however, they reported more positive outcomes than adolescents who had a chronic disease themselves.Conclusion: Having a (family member with a) chronic disease is associated with impaired psychosocial functioning on various life domains. Our findings aid in understanding the psychosocial associates of chronic disease and imply that caregivers should be observant of psychosocial problems among vulnerable adolescents to provide appropriate guidance.What is Known:• Adolescents who grow up with a (family member with a) chronic disease encounter numerous challenges that may be related to poorer developmental outcomes on the long term.What is New:• This study adds a comprehensive overview of the psychosocial functioning of adolescents with a (family member with a) chronic disease, as compared to healthy counterparts that grow up in a healthy family.

Waterpipe smoking and subsequent cigarette and e-cigarette use: a cohort study.

AimWe tested the hypothesis that waterpipe smoking increases the likelihood to try conventional and electronic cigarettes.MethodsIn 2017 and 2018, 2752 German adolescents (mean age: 14.9 years), who had never tried conventional cigarettes or e-cigarettes, took part in a longitudinal survey with a 6-month observational period. Multiple regression analyses tested the association between waterpipe use at baseline and first experimentation with e-cigarettes at follow-up. The models adjusted for risk-taking propensity (sensation seeking and experimentation with alcohol and marijuana), age, sex, migration background, type of school and peer substance use.ResultsSome 381 adolescents (12.5% of the survey population) reported waterpipe smoking at baseline. The overall initiation rate during the 6 months was 4.9% (n=134) for conventional cigarettes and 10.5% (n=288) for e-cigarettes. Prior waterpipe smoking significantly predicted cigarette use (adjusted relative risk (ARR)=1.81, 95% CI 1.19–2.76), as well as e-cigarette use (ARR=3.29, 95% CI 2.53–4.28). In addition, a significant interaction between waterpipe use and sensation seeking was found (ARR=0.56, 95% CI 0.33–0.95), with waterpipe use being more predictive of later e-cigarette initiation for lower sensation-seeking individuals.DiscussionWaterpipe use predicted both later cigarette and e-cigarette use independent of all other assessed risk factors, indicating that waterpipe use might be a risk factor on its own. The results suggest that the association was stronger for adolescents with a lower risk-taking propensity, which brings this group into focus for prevention efforts. However, further research is needed to understand whether these associations are causal.

Mapping Pathways by Which Genetic Risk Influences Adolescent Externalizing Behavior: The Interplay Between Externalizing Polygenic Risk Scores, Parental Knowledge, and Peer Substance Use.

Genetic predispositions and environmental influences both play an important role in adolescent externalizing behavior; however, they are not always independent. To elucidate gene-environment interplay, we examined the interrelationships between externalizing polygenic risk scores, parental knowledge, and peer substance use in impacting adolescent externalizing behavior across two time-points in a high-risk longitudinal sample of 1,200 adolescents (764 European and 436 African ancestry; Mage = 12.99) from the Collaborative Study on the Genetics of Alcoholism. Results from multivariate path analysis indicated that externalizing polygenic scores were directly associated with adolescent externalizing behavior but also indirectly via peer substance use, in the European ancestry sample. No significant polygenic association nor indirect effects of genetic risk were observed in the African ancestry group, likely due to more limited power. Our findings underscore the importance of gene-environment interplay and suggest peer substance use may be a mechanism through which genetic risk influences adolescent externalizing behavior.

Peer and Community Influences on Adolescent Substance Use in the Context of Adverse Childhood Experiences.

Both adverse childhood experiences (ACEs) and peer influences consistently predict early tobacco, alcohol, and illicit drug use. However, less research considers how peer and community influences contribute to or modify the association between ACEs and early substance use. This study addresses these gaps in the literature by analyzing multilevel, longitudinal data from the Project on Human Development in Chicago Neighborhoods (PHDCN; N = 1,912). Unstructured socializing and peer substance use largely explained the association between ACEs and drinking, smoking cigarettes, and illicit drug use in the past month. A history of ACEs magnified the association between peer substance use and the number of cigarettes smoked. Collective efficacy also shaped the associations between peer influences, ACEs, and substance use, but in different ways depending on the substance use outcome analyzed.

Psychosocial predictors of substance use in adolescents and young adults: Longitudinal risk and protective factors

Many psychosocial factors have been implicated in the onset and escalation of substance use in adolescence and young adulthood. Typically, each factor explains a small amount of the variance in substance use outcomes, and effects are typically applied across a broad range of ages or computed from cross-sectional data. The current study evaluated the association of factors including social influence (e.g., peer substance use), cognitive features (e.g., alcohol expectancies), and personality and emotional characteristics (e.g., impulsivity and typical responses to stress) in substance use throughout adolescence and emerging adulthood (ages 13–25; N = 798). Mixed-effects models tailored for the accelerated longitudinal design employed in this study were constructed with psychosocial and developmental factors predicting alcohol and cannabis use. As most participants in the sample exhibited little or no substance use at baseline by design, we excluded baseline assessments and examined data from follow-up years 1, 2, 3, and 4. Interactions between age cohort, change in age, and psychosocial predictors of substance use revealed differing associations over the developmental window for alcohol and cannabis use. For example, positive alcohol expectancies and sensation seeking were most strongly associated with greater drinking after age 18, whereas sensation seeking was associated with increased cannabis use as early as age 15. Higher emotion regulation skills led to less cannabis use in younger ages (i.e., shallower slopes below age 17), but this protective effect diminished after age 17. Results highlight developmentally important factors that differentially contribute to substance use in adolescence and young adulthood. We also demonstrate the importance of developmentally sensitive analyses that maximize the value of data from accelerated longitudinal designs.

Effects of a Brief Web-Based "Social Norms"-Intervention on Alcohol, Tobacco and Cannabis Use Among German University Students: Results of a Cluster-Controlled Trial Conducted at Eight Universities.

Background and Aim: “Social norms” (SN)-interventions are aimed at changing existing misperceptions regarding peer substance use by providing feedback on actual norms, thereby affecting personal substance use. It is unknown whether SN-intervention effects previously demonstrated in US students can be replicated in German students. The aim of the INSIST-study was to examine the effects of a web-based SN-intervention on substance use.Design: Cluster-controlled trial.Setting: Eight Universities in Germany.Participants and Measurements: Students were recruited at four intervention vs. four delayed intervention control Universities. 4,463 students completed baseline, 1,255 students (59% female) completed both baseline and 5-months follow-up web-based surveys on personal and perceived peer substance use. Intervention participants received feedback contrasting personal and perceived peer use with previously assessed use and perceptions of same-sex, same-university peers. Intervention effects were assessed via multivariable mixed logistic regression models.Findings: Relative to controls, reception of SN-feedback was associated with higher odds for decreased alcohol use (OR: 1.91, 95% CI 1.42-2.56). This effect was most pronounced in students overestimating peer use at baseline and under or accurately estimating it at follow-up (OR: 6.28, 95% CI 2.00-19.8). The OR was 1.33 (95% CI 0.67-2.65) for decreased cannabis use in students at intervention Universities and was statistically significant at 1.70 (95% CI 1.13-2.55) when contrasting unchanged and decreased with increased use. Regarding tobacco use and episodes of drunkenness, no intervention effects were found.Conclusions: This study was the first cluster-controlled trial suggesting beneficial effects of web-based SN-intervention on alcohol and cannabis use in a large sample of German University students.Clinical Trial Registration: The trial registration number of the INSIST-study is DRKS00007635 at the “German Clinical Trials Register.”

Development of individuals’ own and perceptions of peers’ substance use from early adolescence to adulthood

This study evaluated how individuals’ own substance use and their perception of peers’ substance use predict each other across development from early adolescence to middle adulthood. Participants were from two longitudinal studies: Fast Track (FT; N = 463) and Child Development Project (CDP; N = 585). Participants reported on their own and peers’ substance use during early and middle adolescence and early adulthood, and their own substance use in middle adulthood. From adolescence to early adulthood, individuals’ reports of their own substance use in a given developmental period predicted reports of their peers’ substance use in the next developmental period more than peers’ substance use in a given developmental period predicted individuals’ own substance use in the next. In the higher-risk FT sample, individuals’ own substance use in early adulthood predicted alcohol, cannabis, and other substance use in middle adulthood, and peers’ substance use in early adulthood predicted cannabis use in middle adulthood. In the lower-risk CDP sample, participants’ own substance use in early adulthood predicted only their own cannabis use in middle adulthood, whereas peers’ substance use in early adulthood predicted participants’ alcohol, cannabis, opioid, and other substance use in middle adulthood. The findings suggest that peer substance use in early adulthood may indicate a greater propensity for subsequent substance use in lower-risk groups, whereas those in higher-risk groups may remain more stable in substance use, with less variability explained by peer contexts.

The moderating role of resilience in the relationship between peer pressure and risky behaviors among nursing students.

To examine the moderating role of resilience in the relationship between peer pressure and risky behaviors among nursing students. A cross-sectional correlational study carried out with 512 students. The mean age was 20.90 ± 1.66. Of the students, 82.4% were females 99.0% were single, 71.5% had moderate socioeconomic status. While peer pressure directly made an effect on whole subdimensions for risky behaviors (p < 0.001), resilience had an effect on antisocial behavior, dropout, eating habits, and suicidal tendency (p < 0.001). Moderation was supported as the relationship between peer pressure and substance use varied by resilience level (p < 0.001). PRACTICALIMPLICATIONS: Students with high levels of resilience are less prone to exhibit some risky behaviors based on peer pressure. Resilience-building strategies should be incorporated into the curriculum.

Pathways to Deviance: Exploring the Relationship between Peer Affiliation, Gang Membership and Youth Misconduct

Deviant peer affiliation and gang membership often act as a catalyst for maladaptive behaviour, as individuals in the late adolescent phase of lifespan development typically share stronger attachment to their peers than to their caregivers. An interrelationship also exists between delinquency and factors such as peer approval of deviance and peer pressure to transgress. This is particularly prevalent when exposed to challenges in the family or school, which typically perpetuate feelings of rejection, leading to a greater likelihood to seek out peers to gain a sense of belonging, support and camaraderie. Despite the importance of these interactions, exposure to antisocial peers or gangs exponentially increase the propensity to transgress, as maladaptive behaviour would be reinforced, thereby decreasing the efficacy of primary and secondary socialisation agents. Moreover, youths may become desensitised to violence, learn to rationalise unlawful behaviour and gain opportunities for crime. Accordingly, a qualitative study was conducted in South Africa to explore peer affiliation and gang membership as a pathway to deviance, based on the unique experiences of 20 detained male youths. The data were obtained through purposive sampling and analysed by frequency or percentage distributions, and also through narrative accounts from the participants. The findings identified deviant peer affiliation (75%) and gang involvement (65%) as key factors which motivated the participants to transgress. Furthermore, the association between peer affiliation, substance abuse, academic failure and truancy was apparent. It is thus envisaged that these findings will stimulate further research, contribute to the existing literature and aid in the development of strategies to manage deviant peer association and gang membership.

Peer Victimization Exposure and Subsequent Substance Use in Early Adolescence: The Role of Sleep Problems.

While sleep problems are positively associated with both peer victimization and substance use, previous studies largely have ignored the indirect role sleep problems may play in this association. This three-wave longitudinal study aimed to determine whether sleep problems might link peer victimization to subsequent substance use. Participants were 986 youth (53.7% female, Mage = 12.32 [SD = 0.54 years], 55.6% White, 24.4% Latinx, 22.8% African American/Black, 11.1% Multiracial/Multiethnic, 13.4% Asian/Pacific Islander, and 6.4% Native American) from three U.S. public middle schools. A structural equation model controlling for multiple potential confounds revealed an indirect effect of peer victimization on substance use through sleep problems. Multiple group analyses indicated that the indirect effect was larger for females than for males. Effects did not differ across school socioeconomic level. The results provide further support to include peer victimization when considering factors that may influence adolescent sleep issues and subsequent substance use.

Associations of parental and peer cross-substance use with 12–17-year-old adolescents’ problematic alcohol use: A parent-child dyadic gender analysis

BackgroundAdolescent alcohol use was found to be influenced by parental and peer alcohol use. Drinking behaviors also differed by gender. However, previous studies mainly focused on adolescents’ substance use in relation to the same substance use among their salient others. Hence, this study investigated the cross-substance relationships of alcohol and tobacco use of parents and peers with adolescents’ problematic alcohol use, separately by gender. MethodsData were derived from 4445 adolescents aged 12–17 years from the 2014 National Survey of Substance Use, a nationally representative survey in Taiwan. Problematic alcohol use was assessed using the Alcohol Use Disorders Identification Test (AUDIT). Multivariate multinomial logistic regression was used, stratified by gender. ResultsFor males, maternal (adjusted odds ratio [aOR] = 1.73) and peer (aOR = 2.57) alcohol use was related to social drinking (AUDIT < 2); paternal (aOR = 3.58), maternal (aOR = 2.18), peer alcohol use (aOR = 5.37), and their own tobacco use (aOR = 4.72) were related to problem drinking (AUDIT ≥ 2). For females, maternal (aOR = 2.26) and peer (aOR = 2.84) alcohol use was related to social drinking; maternal (aOR = 2.35) and peer tobacco use (aOR = 3.48), and paternal (aOR = 4.56) and peer alcohol use (aOR = 3.36) were linked to problem drinking. ConclusionsBoth male and female adolescents’ alcohol use was associated with their peer alcohol use, and gender differences were found in relation to their parental and peer substance use. Specifically, the parental role-modeling of smoking was only significant in mother-daughter dyads. These findings could inform multifaceted adolescent alcohol prevention programs, tailoring for males and females and also targeting their parental and peer substance use.

Residential Greenspace and Urban Adolescent Substance Use: Exploring Interactive Effects with Peer Network Health, Sex, and Executive Function.

While urban greenspace is increasingly recognized as important to mental health, its role in substance use is understudied. This exploratory study investigates the interaction of greenspace with peer network health, sex, and executive function (EF) in models of substance use among a sample of disadvantaged, urban youth. Adolescents and their parents were recruited from a hospital in the mid-Atlantic region of the U.S. Residential greenspace at the streetscape level was derived from analysis of Google Street View imagery. Logistic regression models were used to test the moderating effect of greenspace on the association between peer network health and substance use, as well as additional moderating effects of sex and EF. The significant negative association of peer network health with substance use occurred only among youth residing in high greenspace environments, a moderating effect which was stronger among youth with high EF deficit. The moderating effect of greenspace did not differ between girls and boys. Greenspace may play an important role in moderating peer influences on substance use among disadvantaged, urban adolescents, and such moderation may differ according to an individual’s level of EF. This research provides evidence of differences in environmental susceptibility regarding contextual mechanisms of substance use among youth, and it informs the development of targeted substance use interventions that leverage social and environmental influences on adolescent substance use.

Sensation seeking and adolescent e-cigarette use

ABSTRACT Background: A growing health concern is e-cigarette use among adolescents. Several correlates of this behavior have been elucidated, but few studies have examined whether sensation seeking is associated with e-cigarette use. The current study explores whether this personality dimension is related to e-cigarette use and whether the relationship is moderated by gender, race/ethnicity, or peer substance use. Methods: The analysis utilized data from 17,858 U.S. 8th – 10th grade students from the 2017 and 2018 Monitoring the Future (MTF) studies, who responded to questions about past 12-month e-cigarette use. The association with sensation seeking and four types of e-cigarette use – nicotine only, marijuana only, flavoring only, or nicotine and marijuana – was explored with a multinomial logistic regression model. Results: The results demonstrated that sensation seeking is positively associated with all four types of e-cigarette use, with a slightly stronger association with e-cigarette use involving marijuana. The associations were not moderated by gender, race/ethnicity, or peer substance use. Conclusions: The analysis suggested that sensation seeking consistently predicted several types of adolescent e-cigarette use. Research using longitudinal data and measures of e-cigarette use by family members and friends is needed, though, to better understand this association.

Peer Information and Substance Use Decision Making in Street-Involved Youth.

In the context of adolescent substance use, peers are a primary source of both influence and information. Substance-related peer information sharing is a relatively understudied phenomenon, particularly in street-involved youth. We recruited 84 youth from a community drop-in center to complete a survey assessing substance use and peer influence on drug use. A subset of youth completed a semi-structured interview assessing factors related to peer information sharing around drug use. Results showed that peer influence was highly relevant to drug use patterns in street-involved youth. Trust in the person supplying information, personal and peer experience, and salience of information played important roles in youths' assessments of drug-related information exchanged with peers. Implications for improving community information dissemination strategies are discussed.

Codevelopment of Delinquency, Alcohol Use, and Aggression Toward Peers and Dates: Multitrajectory Patterns and Predictors.

We aimed to characterize developmental patterns of involvement in alcohol use, delinquency, and interpersonal aggression in a normative sample of adolescents by applying multitrajectory group-based modeling. Using seven waves of data from a cohort sequential study spanning the 6th to 12th grades (n=2,825; 50% girls), we identified four distinct trajectory groups: low risk (33%), declining peer aggressors (44%), peer and dating aggressors (13%), and multidomain high risk (10%). Across all comparisons, girls were more likely than boys to be members of the peer and dating aggressor group and less likely to be members of the multidomain high-risk group. Moreover, individual (self-control, negative emotionality), family (family violence, parental monitoring), and peer (substance use norms) distinguished class membership.
