The role of risk and protective factors in substance use across adolescence

Past 30-Day Cannabis Use by Perception of Risk and Age Group: Implications for Prevention

PurposeThe use of cannabis is an important public health concern in the United States. The connection between perceived risk and cannabis use has been documented in the substance use literature for youth and adults.DesignExamine how past 30-day cannabis use is influenced by the interaction between perceived risk and age.SubjectsNationally representative sample of individuals ages 12 and older in the United States.MeasuresSecondary data analysis of the 2021 National Survey on Drug Use and Health (N = 58, 034).AnalysisBinary logistic regression that included the complex sampling elements of the survey.ResultsSupport was found for an interaction between age and perceived risk. Most notably, the sharpest increase in the probability of cannabis use occurred between the 12-17 and 18-25 year-old age groups for no/low risk perception.ConclusionAddressing the perceived risk of cannabis use at younger ages - specifically adolescence - may be an important prevention strategy for later cannabis use. Results directly inform preventive interventions regarding by indicating the age groups that at are at a higher probability for using cannabis based on perceived risk levels. This study adds to the literature by directly testing an interaction between perceived risk and age on the probability of using cannabis in the past 30-days at the population level.

Comorbid Cannabis Use and Mood Disorders Among Adolescents

Adolescence is a unique developmental period marked by increased exploration and risk-taking, as well as important brain development milestones. Many people who use substances will begin using during adolescence, and cannabis is the most commonly used illicit substance among adolescents. For adolescents with mood disorders, cannabis use (and, by extension, cannabis use disorder) is even more likely, and the associated consequences are even more significant. In this review, we explore the assessment of cannabis use disorder among adolescents, the impact of cannabis use on mood symptoms, level-of-care recommendations for adolescents with comorbid cannabis use and mood disorders, and effective treatment options.

Cumulative psychosocial and health disparities in US adolescent cigarette smoking, 2002-2019

BACKGROUND

Understanding disparities in adolescent cigarette smoking is important for effective prevention.

METHODS

We investigated disparities in adolescent smoking based on cumulative reported psychosocial and health risk among respondents ages 12-17 years in the US National Survey of Drug Use and Health from 2002 to 2019. Multivariable regression estimated associations of cumulative risk, survey years, and their interaction predicting past-month and daily smoking. Eleven psychosocial and health variables associated with youth smoking formed composite measures of cumulative risk, categorizing risk as low (0-2), moderate (3-4), or high (≥5). The main outcomes were weighted past-month and daily smoking by cumulative risk and time, examining prevalence and proportional change across years.

RESULTS

Among 244 519 adolescents, greater cumulative risk predicted higher smoking prevalence across all outcomes. Compared with the low-risk category, past-month smoking odds (adjusted odds ratio) were 9.14 (95% confidence interval [CI] = 8.58 to 9.72) and 46.15 (95% CI = 43.38 to 49.10) times greater in the moderate-risk and high-risk categories. For daily smoking, odds were 14.11 (95% CI = 11.92 to 16.70) and 97.32 (95% CI = 83.06 to 114.03) times greater among the moderate-risk and high-risk categories. Regarding proportional change, the low-risk category exhibited the steepest decline (-85.1%) in past-month smoking from 2002-2003 to 2018-2019, followed by the moderate-risk (-79.2%) and high-risk (-65.7%) categories. Daily smoking declined more steeply among the low-risk (-96.5%) and moderate-risk (-90.5%) than high-risk category (-86.4%).

CONCLUSIONS

Cumulative risk is a robust predictor of adolescent smoking. Although record-setting reductions in adolescent smoking extend across risk categories, disparities favoring youth with fewer risks are evident throughout. Recognizing cumulative risk can inform the development of more targeted and effective prevention efforts.

Rehabilitative measures as a legal response for adolescents convicted for drug offences: The Swedish system

Aims: Involvement in minor drug offences at an early age can be a signal of the onset of a potential drug issue. This is why Sweden has considered the criminalization of personal use as a strategy to deter the progression of drug use. This study investigated how the judiciary and social services succeed in identifying and providing support to adolescents convicted of drug offences. Methods: Characteristics of all 15-17-year-olds convicted of offences against the Act on Penal Law on Narcotics (drug offence) in 2017 were examined using Swedish longitudinal registry data (N = 1847). Furthermore, the decision process rendering different legal responses was examined by use of social services files for a subsample of 189 adolescents. Results: About two-thirds of the adolescents had their first conviction for the index offence and the majority received legal responses consisting of rehabilitative measures. Background factors indicated that those with severe drug and criminal issues encounter risk factors relating to their upbringing (e.g., neuropsychiatric disorders were notably more prevalent in this group than among similar peers). Around 61% of adolescents were reconvicted for new drug offences during the three-year study period, but with variations among subgroups. Younger boys who received rehabilitative measures had lower reconviction rates compared to those without. Conclusions: Addressing the underlying factors contributing to adolescent drug offences requires a multifaceted approach that prioritizes early intervention, personalized support, and collaboration across systems to promote positive outcomes and reduce recidivism rates.

Cumulative Risk and Cumulative Protection: Relative Contributions to Predicting Substance Use, Antisocial Behaviour and Mental Health Across Development

BACKGROUND

Cumulative risk scores predict negative outcomes including antisocial behaviour and mental health. Less work has examined the role of cumulative protection, despite the availability of preventive interventions focused on bolstering protection across domains. Understanding links between cumulative risk and protection measured in childhood and later outcomes can help to guide the timing of prevention programmes.

AIMS

The study aimed to understand the relative contributions of early adolescent cumulative risk and cumulative protection in Grade 6 on distal outcomes six to seven years later, at ages 18-19.

METHODS

Data are from the Community Youth Development Study, a community-randomised trial of the Communities That Care prevention system. The analysis sample consisted of 2002 participants from 12 control communities. Logistic regression models were estimated to quantify the main and interactive effects of Grade 6 cumulative risk and protection on alcohol, tobacco and cannabis use; antisocial behaviour, and depression at ages 18-19.

RESULTS

When considered in separate models, cumulative risk and protection were each associated with later alcohol, tobacco and cannabis misuse; antisocial behaviour and depression. When considered together, coefficients for cumulative protection were attenuated, whereas coefficients for cumulative risk remained similar in magnitude. Cumulative risk was associated with larger outcome prevalence differences (average of 9%) than cumulative protection (average of 2%). Evidence for risk-protection interactions was not observed.

CONCLUSIONS

Although early adolescent cumulative protection was associated with later outcomes, these associations were largely reduced when considering cumulative risk. Findings emphasise the importance of addressing cumulative risk when designing preventive interventions.

Neighborhood Violence Exposure and Alcohol and Tobacco Use Initiation Among Ethnic Minority Adolescents

Background/Objectives: Although the extant literature has recognized the importance of neighborhood contexts for adolescent alcohol and tobacco use, less is known about the effects of exposure to neighborhood violence on the prevalence and timing of initiation across gender and race/ethnic groups. Methods: This secondary analysis of administrative and survey data from a natural experiment in Denver examines the influence of neighborhood contexts on the health and well-being of 1100 Latino/a and African American adolescents. Cox Proportional Hazard models were used to (1) estimate the effects of exposure to neighborhood violence on the prevalence and timing of adolescent alcohol and tobacco use initiation; (2) examine gender and race/ethnic variations in alcohol and tobacco use initiation after controlling for adolescent, caregiver, household, and other neighborhood characteristics; and (3) test for threshold effects. Results: Prevalence rates among all adolescents were 12.9% for alcohol use initiation and 13.7% for tobacco use initiation but were 14.6% and 17.3%, respectively, among adolescents exposed to higher levels of neighborhood violence. The average age of initiation was 16.1 and 15.6 years for alcohol and tobacco use, respectively, but 2-8 months earlier for adolescents exposed to higher levels of neighborhood violence. Heightened exposure to neighborhood violence increased the hazards of alcohol use initiation by 32% for all adolescents and 38% for adolescent males. The hazards of tobacco use initiation were 1.3 to 1.5 times higher for male, Latino/a, and African American adolescents. Exposure to neighborhood violence suggests threshold effects of diminishing returns on adolescent tobacco use initiation. Conclusions: Findings underscore the need to examine gender and race/ethnic group differences in adolescent alcohol and tobacco initiation, the multiple pathways to such use, and interventions aimed at reducing neighborhood violence.

Effects on alcohol and substance use of a school-based training intervention for adolescents with ADHD

INTRODUCTION

Adolescents with attention-deficit/hyperactivity disorder (ADHD) may be at risk for early, escalating patterns of alcohol and substance use via academic, peer, and familial impairment. Existing school-based interventions for youth with ADHD effectively target these risk factors, yet their effects on alcohol and substance use have not been explored. We examined the immediate and long-term alcohol and substance use outcomes of an evidence-based school-based intervention for adolescents with ADHD.

METHOD

A total of 186 (Mage = 15, 79% boys, 78% White, 11% Hispanic) adolescents with ADHD were randomized to either a school-based training intervention targeting academic and social skills or a treatment-as-usual control group. A subset of youth was followed into emerging adulthood (5 year follow-up; n = 73). Participants reported on their alcohol and substance use behaviors and problems at post-treatment, 6-month follow-up, and 5-year follow-up.

RESULTS

Two-part hurdle models controlling for prior use and demographics indicated treatment was associated with improvements in substance use outcomes among youth using any substances at 6-month follow-up (β = -0.45). However, among youth reporting any alcohol use at the 5-year follow-up, treatment was associated with worse alcohol use problems relative to the control condition (β = 0.27). Approximately 22% of intervention participants met criteria for risky drinking behavior compared to 5% of participants in the control group.

CONCLUSION

We found mixed evidence that a school-based intervention associated with positive outcomes on academic, social, and emotional functioning for adolescents with ADHD also prevented adverse alcohol and substance use outcomes. These unexpected results serve as a call for extended follow-up periods to identify the durability of intervention benefits and potential for downstream iatrogenic effects. Additional research is needed to identify school-based intervention strategies that can effectively deter substance use risk among select populations.

School Connectedness and Adolescent E-cigarette Susceptibility in an Urban Sample of Middle and High School Students

Adolescent school connectedness generally protects from risk behaviors such as tobacco use; however, its relationship to e-cigarette use is unclear. This study examines the relationship between adolescent school connectedness and e-cigarette susceptibility in a diverse longitudinal sample. This secondary analysis of a school-based intervention surveyed 608 middle (66%) and high school (34%) students from 10 schools at 3 time points over 1 year. At baseline, respondents had a mean age of 14 years, 54% were female, and 71% were BIPOC (Black, Indigenous, People of Color). Logistic regression models examined unadjusted and adjusted associations between school connectedness (both baseline and concurrent) and e-cigarette susceptibility over time. E-cigarettes represented the most prevalent form of current nicotine-containing product use in spring 2019 (2.3%), and most respondents reported no e-cigarette susceptibility (69%). E-cigarette susceptibility remained relatively stable during the study. Higher baseline school connectedness levels were associated with lower odds of e-cigarette susceptibility over time. Similarly, higher concurrent school connectedness scores were associated with lower odds of e-cigarette susceptibility over time: spring 2019 (OR, 0.39; 95% CI, 0.32, 0.47), fall 2019 (OR, 0.49; 95% CI, 0.34, 0.72), and spring 2020 (OR, 0.64; 95% CI, 0.47, 0.87). Findings were similar for middle and high school students and did not differ significantly after adjusting for other covariates. Adolescents' school connectedness appears to protect from e-cigarette susceptibility over time, underscoring the importance of promoting positive school experiences to reduce adolescent risk e-cigarette use.

Sexual Behaviors in Iranian Working Children and the Correlated Risk Factors: Result of the Large-Scale Rapid Assessment and Response (RAR) Survey

This study aimed to investigate the sexual behaviors among working children and the associated factors. This cross-sectional study was conducted on a sample of 1937 working children in the 10-18 age range in 15 provincial capitals in 2019-20 (Feb-May); the Response rate was 94.9%. Univariate and multivariable logistic regression was used to examine the variable of sexual behaviors. Adjusted odds ratios (AOR) and 95% confidence intervals (CI) are reported. The prevalence of sexual behaviors in working children was 4.2%. The results showed a significant difference between those who reported sexual behaviors and those who did not in terms of age, identity document (ID), running away from home, alcohol use, and substance use. There was a statistically significant relationship between fathers' unemployment and sexual behaviors among working children. Furthermore, we found that having divorced parents could increase the odds of sexual behaviors by 3.74 times. The findings showed that related welfare and support organizations should design and implement effective and continuous training and interventions to raise awareness and reduce the prevalence of high-risk sexual behaviors in working children. They should also provide family counseling and promote parental supervision of children.

Advancing Understanding on Greenspace and Mental Health in Young People

Mental distress among young people has increased in recent years. Research suggests that greenspace may benefit mental health. The objective of this exploratory study is to further understanding of place-based differences (i.e., urbanity) in the greenspace-mental health association. We leverage publicly available greenspace data sets to operationalize greenspace quantity, quality, and accessibility metrics at the community-level. Emergency department visits for young people (ages 24 and under) were coded for: anxiety, depression, mood disorders, mental and behavioral disorders, and substance use disorders. Generalized linear models investigated the association between greenspace metrics and community-level mental health burden; results are reported as prevalence rate ratios (PRR). Urban and suburban communities with the lowest quantities of greenspace had the highest prevalence of poor mental health outcomes, particularly for mood disorders in urban areas (PRR: 1.19, 95% CI: 1.16-1.21), and substance use disorders in suburban areas (PRR: 1.35, 95% CI: 1.28-1.43). In urban, micropolitan, and rural/isolated areas further distance to greenspace was associated with a higher prevalence of poor mental health outcomes; this association was most pronounced for substance use disorders (PRRUrban: 1.31, 95% CI: 1.29-1.32; PRRMicropolitan: 1.47, 95% CI: 1.43-1.51; PRRRural 2.38: 95% CI: 2.19-2.58). In small towns and rural/isolated communities, poor mental health outcomes were more prevalent in communities with the worst greenspace quality; this association was most pronounced for mental and behavioral disorders in small towns (PRR: 1.29, 95% CI: 1.24-1.35), and for anxiety disorders in rural/isolated communities (PRR: 1.61, 95% CI: 1.43-1.82). The association between greenspace metrics and mental health outcomes among young people is place-based with variations across the rural-urban continuum.

What Protects At-Risk Young People in India From Using and Abusing Substances? A Photo-Led Study of Lived Experience

Youth substance abuse is widespread in India. Data is needed to inform the focus of prevention approaches. Our aim was to understand the perspectives of Indian young people about what protects them from substance (ab)use, and our study followed protocols approved by UK and Indian university research ethics committees. We recruited 15 Indian adolescents from Assam (seven males, eight females) aged 15 to 18 years at elevated risk because they had family/friends who were substance addicts. Participants took part in a photo-led interview in which they represented visually and narratively their experience of resisting substances (ab)use. Data were analyzed by a UK-India team using reflexive thematic analysis. Seven dominant protective factors were expressed by young people, including nurturing and communicative relationships with parents; up close and personal observations around addiction which left participants fearful of substances; protective mindsets and resolutions emerging from participants’ reflection on drug culture; staying away from “bad” company; being repulsed by substances; having healthy ways to cope at difficult times; and having something that mattered more than using substances. Findings show the resilience of Indian adolescents and suggest that prevention approaches in India should focus on augmenting individual, school and family mechanisms which appear dynamic and cumulative.

Pathways to substance use: Examining conduct problems and parenting behaviors from preschool to adolescence

While many studies have identified risk and protective factors of substance use (SU), few have assessed the reciprocal associations of child conduct problems (CP) and parenting practices and behaviors in the prediction of SU across development. A greater understanding of how these factors relate over time is needed to improve the timing of targeted prevention efforts. This study examined how child CP, parenting behaviors, and parents' own antisocial behavior relate from preschool to adolescence and eventuate in SU. Participants included 706 youth (70.6% male; 89.7% white) enrolled in the Michigan Longitudinal Study. Data from waves 1 (ages 3-5), 2 (ages 6-8), 3 (ages 9-11), 4 (ages 12-14), and 5 (ages 15-17) were included. A random intercept cross-lagged panel model (RI-CLPM) examined reciprocal associations between parenting practices, parents' antisocial behavior, and child CP over time (waves 1-4) and how these factors contribute to adolescent alcohol, cigarette, and marijuana use (wave 5). At the within-person level, negative parenting and parents' own antisocial behavior had a strong influence in late childhood/early adolescence. Only child CP emerged as a significant predictor of SU. Results highlight the importance of early intervention and the potential influence of parenting and child factors throughout development in the prevention of SU.

Sociocultural determinants of alcohol and cannabis use and misuse among Nunavimmiut

OBJECTIVE

Stemming from historical traumas and changes in the Inuit way of life, substance use and its intertwined problems are a major cause of concern for Nunavimmiut. This study's objective is to investigate sociocultural determinants of substance use and misuse to inform culturally appropriate public health programs.

METHODS

The 2017 Qanuilirpitaa? survey was conducted among a sample intended to be representative of Nunavimmiut aged 16 and over (total n = 1326). Sociocultural factors included cultural identity, land-based activities, involvement in community activities, social support, and family and community cohesion. The frequency of binge drinking (5 or more drinks on one occasion), cannabis use, and problematic substance use (CAGE and DAST-10) were documented. Data were analyzed using weighted multivariate logistic regressions. Inuit partners were involved from the planning of analyses to the co-interpretation of results.

RESULTS

Nearly a third of Nunavimmiut aged 16 and over reported binge drinking at least once a week (29.3%), and 68.6% of drinkers were at risk of potential drinking problems. Forty-five percent (45%) reported using cannabis at least once a week, and 30% of drug users were at risk of potential drug abuse problems. Volunteering and participation in community activities were associated with lower odds of cannabis use, as was frequently going on the land with weekly binge drinking, potential drinking problems, and weekly cannabis use. Social support and community cohesion were associated with higher odds of weekly binge drinking, as was cultural identity (centrality scale) with potential drinking problems.

CONCLUSION

Key determinants of substance use relevant to Inuit culture were identified. Results are in line with our Inuit partners' experience in their communities and are coherent with current land-based interventions implemented in Nunavik. A thorough understanding of substance use contexts and related stressors should guide the content and implementation of substance use programs in Nunavik.

Correlates of adolescent sole-, dual- and poly-use of cannabis, vaped nicotine, and combusted tobacco

BACKGROUND

Compared to single substance use, adolescents' use of multiple substances is associated with more severe dependence, cessation outcomes, and health risks. This study examined correlates of use and co-use of e-cigarettes, combusted tobacco, and cannabis among high school-aged (9th-12th grade, approximately aged 14-18) adolescents.

METHODS

We analyzed the 2019 Massachusetts Youth Health Survey (MYHS) data to calculate the weighted means of any past 30-day sole-use of e-cigarettes, sole-use of combusted tobacco, sole-use of cannabis, dual-use of two of the above substances, and poly-use of all three substances. We then used weighted multinomial logistic regression to examine the associations between demographic, social and behavioral factors and sole-, dual-, and poly-use (vs. no use) of these substances.

RESULTS

Among N = 1614 respondents, any past 30-day dual-use of e-cigarettes and cannabis was the most prevalent (17.2%, SE: 1.3%). Sole-use of combusted tobacco was less than 1%, whereas 4.5% (SE: 0.7%) of respondents reported poly-use of e-cigarettes, cannabis, and combusted tobacco. Lower academic grades and self-reported depression (1 item on persistent feelings of sadness or hopelessness) were associated with increased odds of dual-use of e-cigarettes and cannabis and poly-use (vs. sole-use of any substance). Adolescents who self-reported having "any long-term emotional problems or learning disabilities" had greater odds of poly-use.

CONCLUSION

Different sets of correlates were associated with sole-, dual-, and poly-use, suggesting that certain adolescents may be more vulnerable than others to multiple substance use. Future research should examine potentially modifiable upstream influences, such as the home environment and socioeconomic factors that may affect the relationship between adolescent mental health, school performance, and multiple addictive substance use.

Associations between Family Factors and Youth Substance Use Across the Rural-Urban Continuum: A Person-/Variable-Centered Approach

Few studies have evaluated the influence of both family factors and geographic location on youth substance use. To address this gap, a person-/variable-centered approach was used to: (1) identify latent profiles of family risk and protective factors for substance use, (2) test profile membership as a predictor of lifetime and 30-day substance use, (3) test rurality, as measured by school geographic location, as a predictor, and (4) explore interaction effects between profile membership and rurality. Youth (N=9,104; 53% female) residing in a state in the southeastern U.S. completed a statewide substance abuse and risk behavior survey including questions about family risk and protective factors and substance use behaviors. Using latent profile analysis to identify subgroups of participants with similar means and variances on the family factors, four latent profiles emerged. Risk of 30-day and lifetime substance use varied across profiles, with the profile characterized by high family-level protective factors and low family-level risk factors indicating the lowest risk for substance use. Urban youth had increased odds of reporting lifetime marijuana use compared to suburban youth; however, geographic location did not appear to confer significantly increased or decreased risk across other substances. No significant interaction results were found. These results emphasize the importance of family functioning on substance use regardless of geographic location, and that evidence-based prevention programming that reduces family risk, strengthens family protection, and is accessible to all types of communities is important to reducing or delaying substance use among youth.

Parental practices and their association with alcohol and cannabis use among adolescents in Chile

Background

Adolescent alcohol and cannabis use are common in Chile. The present study aimed to assess the relationship between perceived parenting practices and alcohol and cannabis use among adolescents in a Latin American context.

Methods

We adapted and implemented a substance use prevention strategy in Chile, which included surveys of tenth-grade students from six municipalities in the Metropolitan Region of Greater Santiago. We assessed the reliability and factorial structure of the parenting scale with 16 items, which formed part of the survey. We dichotomized parenting scores into high (above the median) and low. The association of parenting practices with alcohol and cannabis use in adolescents was assessed using multivariate multilevel regression models.

Results

A total of 7,538 tenth-grade students from 118 schools were included in the study. The 16-item scale of parenting practices showed good internal consistency (Omega total = 0.84), and three factors representing Relationship between parents and adolescents, Norms and monitoring, and Parents knowing their children's friends and the parents of their children's friends. High total scores of parenting were associated with lower odds of lifetime alcohol use (OR 0.57; 95% CI: 0.49-0.65), past-month alcohol use (OR 0.63; 95% CI: 0.57-0.70), lifetime drunkenness (OR 0.64; 95% CI: 0.58-0.72), and lifetime cannabis use (OR 0.54; 95% CI: 0.47-0.61). Above median scores on each parenting subscale were associated with significantly lower odds of substance use. The strongest associations were observed for the subscale Norms and monitoring. Interactions between parenting and gender showed a significantly stronger effect of parenting practices on alcohol and cannabis use among girls.

Conclusion

Different types of parenting practices were associated with a lower prevalence of adolescent alcohol and cannabis use. Improving parenting practices has the potential to prevent adolescent substance use in Chile, especially among girls.

Change in marijuana use from adolescence to young adulthood and its relation to gestational alcohol and marijuana exposure

INTRODUCTION

Many studies have examined changes in marijuana use across adolescence, but few have examined factors associated with transitions from adolescence to young adulthood. We examined prenatal exposures to alcohol and marijuana and adolescent risk and protective factors that best distinguished among abstinence, continuity, or cessation of marijuana use from 16 to 22 years.

METHOD

Data were from the Maternal Health Practices and Child Development Project at the prenatal and 16- and 22-year follow-up phases. The offspring were of lower socioeconomic status with an average of 12.8 years of education at 22 years. Participants' frequency and quantity of marijuana use over the past year were used to determine change in use. A discriminant analysis was applied to distinguish among the identified groups. The risk factors considered included prenatal substance exposures and age 16 demographics, behavior, and home environment.

RESULT

Four categories of transitions were defined based on marijuana use from 16 to 22 years: non-users (n = 193), stop/decrease (n = 81), continue at same level/increase (n = 125), and initiation after the 16-year phase (n = 122). The factors that best distinguished among these groups were peers' marijuana use, delinquency, caregivers' financial strain, prenatal exposure to alcohol and marijuana, and race.

CONCLUSION

Prenatal alcohol and marijuana exposure were significantly related to transitions of marijuana use from adolescence to young adulthood, controlling for peers' use, behavior problems, and home environment. While gestational marijuana exposure was associated with early initiation/increasing use, alcohol exposure was related to later initiation. The findings emphasize the long-term effects of prenatal exposure to alcohol and marijuana.

Transforming stress program on medical students' stress mindset and coping strategies: a quasi-experimental study

OBJECTIVE

Stress is a significant concern in medical education, and identifying effective ways to deal with stress may help with students' mental health and professional development. This study aimed to examine the effects of the Transforming Stress Program (TSP) amongst first-year medical students on their stress mindset and coping strategies when confronted with stressors.

METHODS

We conducted a quasi-experimental study at the University of Medicine and Pharmacy, Ho Chi Minh City, Vietnam. A total of 409 first-year students at the Faculty of Medicine were divided into intervention group (205 students) and control group (204 students). The 10-week TSP was delivered as an extra-curricular course. The training adopts psychoeducation based on Dialectical Behavioral Therapy with mindfulness as a fundamental practice incorporated into each component of the program. The intervention group received the training in the first semester; the control group received identical program in the second semester. Stress Mindset Measurement and Brief Coping Orientation to Problems Experienced were measured before the intervention (T0), immediately after intervention on Intervention group (T1), and six months after intervention on Intervention group (T2).

RESULTS

At T1, the intervention group showed 65% improvements in stress mindset scores and increases in coping strategies scores in six domains (Problem solving, Social support, Humor, Religion, Venting, and Self-distraction) and decreases in three (Avoidance, Substance use, and Self-blame). The effect sizes were significant in all outcomes (Cohen's d > 0.2). Measurements of the control group did not change significantly in the same period. At T2, effects of the TSP were found decreased in some domains (Avoidance, Substance use, and Self-blame) compared to T1, but largely remained significantly better than T0.

CONCLUSIONS

The TSP is a feasible and effective approach that significantly enhanced medical students' stress mindset and coping strategies. Some effects were still observable 6 months after the intervention. The relatively intensive intervention requires support of the school administration and staff.

Prospective, longitudinal study to isolate the impacts of marijuana use on neurocognitive functioning in adolescents

Introduction

Policies to legalize possession and use of marijuana have been increasingly supported across the United States. Although there are restrictions on use in minors, many substance abuse scientists anticipate that these policy changes may alter use patterns among adolescents due to its wider availability and a softening of beliefs about its potentially harmful consequences. Despite the possibility that these policies may increase the prevalence of use among adolescents, the effects of marijuana on neurodevelopment remain unclear, clouding arguments in favor of or opposition to these policies.

Methods

The present prospective, longitudinal study was designed to isolate the neurodevelopmental consequences of marijuana use from its precursors during adolescence-a period of heightened vulnerability for both substance use and disrupted development due to environmental insults. Early adolescents who were substance-naïve at baseline (N = 529, aged 10-12) were recruited and tracked into adolescence when a subgroup initiated marijuana use during one of three subsequent waves of data collection, approximately 18 months apart.

Results

Results suggest that marijuana use may be specifically related to a decline in verbal learning ability in the short term and in emotion recognition, attention, and inhibition in the longer-term.

Discussion

These preliminary findings suggest that marijuana use has potential to adversely impact vulnerable neurodevelopmental processes during adolescence. Intensive additional investigation is recommended given that state-level policies regulating marijuana use and possession are rapidly shifting in the absence of good scientific information.

The Influence of Risk and Protective Factors on Adolescent Alcohol, Cannabis, and Electronic Cigarette Use

The misuse of substances by adolescents is a serious public health concern in the United States, and the three most used substances by adolescents are alcohol, cannabis, and electronic cigarettes. In accordance with the Social Development Model, a better understanding of the risk and protective factors across these three substances can assist in predicting potential substance use as well as strategies for prevention. The purpose of the current study is to examine the similar or differential influence that a specific set of risk and protective factors (i.e., favorable attitudes toward substance use, perceived risk of harm, peer substance use, interaction with prosocial peers, parental favorable attitudes toward substance use, family management, perceived availability substances, and rewards for prosocial involvement) have on past 30-day alcohol, cannabis, and e-cigarette use by adolescents. The present study is based on a secondary data analysis of the 2019 Prevention Needs Assessment Survey, which is administered every two years in the State of Utah to a large sample of students in grades 6, 8, 10, and 12 grades. A subsample of students (n = 44,728) was included in the present analysis. Logistic regression was used to examine the predictive relation for the set of four risk and four protective factors on past 30-day use of alcohol, cannabis, and e-cigarette use. In general, the results indicated that endorsement of the four risk factors predicted increases in the use of each substance whereas endorsement of the four protective factors predicted decreases in use. Implications of these findings suggest that there may be more similarities in risk and protective factors across alcohol, cannabis, and electronic cigarettes than between them. In addition, this study adds to the budding literature on the risk and protective factors associated with adolescent e-cigarette use.

Using machine learning to determine the shared and unique risk factors for marijuana use among child-welfare versus community adolescents

OBJECTIVE

This study used machine learning (ML) to test an empirically derived set of risk factors for marijuana use. Models were built separately for child welfare (CW) and non-CW adolescents in order to compare the variables selected as important features/risk factors.

METHOD

Data were from a Time 4 (Mage = 18.22) of longitudinal study of the effects of maltreatment on adolescent development (n = 350; CW = 222; non-CW = 128; 56%male). Marijuana use in the past 12 months (none versus any) was obtained from a single item self-report. Risk factors entered into the model included mental health, parent/family social support, peer risk behavior, self-reported risk behavior, self-esteem, and self-reported adversities (e.g., abuse, neglect, witnessing family violence or community violence).

RESULTS

The ML approaches indicated 80% accuracy in predicting marijuana use in the CW group and 85% accuracy in the non-CW group. In addition, the top features differed for the CW and non-CW groups with peer marijuana use emerging as the most important risk factor for CW youth, whereas externalizing behavior was the most important for the non-CW group. The most important common risk factor between group was gender, with males having higher risk.

CONCLUSIONS

This is the first study to examine the shared and unique risk factors for marijuana use for CW and non-CW youth using a machine learning approach. The results support our assertion that there may be similar risk factors for both groups, but there are also risks unique to each population. Therefore, risk factors derived from normative populations may not have the same importance when used for CW youth. These differences should be considered in clinical practice when assessing risk for substance use among adolescents.

Risk factors for substance use in Swedish adolescents: A study across substances and time points

Aim: The public health model for prevention of disease and disorder has been influential in informing interventions regarding substance use. While a number of risk factors within this model have been found to predict substance use, few studies have explored the associations across substances, at different time points and in the same individuals. The aim of this study was to test this model across legal and illegal substance use among adolescents, and to identify potential changes in associations over time. Methods: Data from two waves of a nationally representative cohort study among Swedish adolescents were used. Baseline data were collected in 2017 (9th grade) with a follow-up in 2019 (11th grade). Using modified Poisson regression analyses, we explored cross-sectional associations between factors from different domains and prevalence of cigarette use, binge-drinking and illegal drug use at both baseline and follow-up. Results: The results in part supported the public health model. Substance use was predicted by factors within the family, school and the individual/peer domain, but several associations were not statistically significant. The only consistent risk factors across substances and time points were lack of parental monitoring, truancy and minor criminal activities. Conclusion: Despite widely different prevalence rates across substances, some risk factors were consistently associated with adolescent substance use. Nonetheless, the findings challenge the assumption that risk factors are stable over adolescence. They suggest a need for flexible prevention interventions spanning across substances and legal boundaries of substances, but also over domains to reflect the heterogenous needs of adolescents.

How Influential are Adverse Childhood Experiences (ACEs) on Youths?: Analyzing the Immediate and Lagged Effect of ACEs on Deviant Behaviors

Although the effect of adverse childhood experiences (ACEs) on antisocial behaviors is well established in the literature, limited research, if any, has analyzed the effect that ACEs have on behaviors at two different times. Limited research also has analyzed the effect that specific ACEs have on deviant behaviors after statistically controlling for respondents' protective factors. This study expands the literature in this area by analyzing in a sample of 555 adolescents the immediate and lagged effect that individual ACEs, and exposure to a number of ACEs, have on three deviant behaviors after controlling for respondents' protective factors not previously examined in ACEs studies. Results obtained from multivariate logistic regression models revealed that stealing things was predicted by being hit hard, being sexually molested, and having lived with a depressed or suicidal individual; and receiving threats over the internet predicted physical fights. Only being hit hard and living with an alcoholic had a lagged effect on smoking marijuana. Results also showed that the protective factors of school connection, anger management skills, and parental supervision reduced the effect of ACEs on the behaviors analyzed. Research, theory, and policy implications are discussed.

Adverse childhood experiences and past 30-day cannabis use among middle and high school students: The protective influence of families and schools

Exposure to adverse childhood experiences (ACEs) is a risk factor for adolescent cannabis use (CU). We explored whether family communication and school connectedness can offer direct protection (the compensatory model of resiliency) or moderating protection (the protective factors model of resiliency). Using cluster random sampling, a Youth Risk Behavior Survey (YRBS) was conducted with 5,341 middle school and 4,980 high school students in 2019. Generalized estimating equations were used to estimate whether family communication and school connectedness offered independent direct protection (multiple regression) or moderating protection (multiplicative interaction) in the relationship between ACEs and past 30-day CU. Adjusted prevalence ratios (APR) and 95% confidence intervals (95% CI) were calculated. There was a graded relationship between ACEs and past 30-day CU for all students that was particularly strong among middle school students: 1 ACE (APR = 2.37, 95% CI = 2.16, 2.62), 2 ACEs (APR = 2.89, 95% CI = 2.60, 3.23), 3 ACEs (APR = 5.30, 95% CI = 4.75, 5.90), 4 + ACEs (APR = 7.86, 95% CI = 7.13, 8.67). Results supported the compensatory model of resiliency with both family communication (middle school APR = 0.90, 95% CI = 0.88, 0.93; high school APR = 0.90, 95% CI = 0.87, 0.93) and school connectedness (middle school APR = 0.76, 95% CI = 0.72, 0.79; high school APR = 0.72, 95% CI = 0.68, 0.77) demonstrating a direct, independent protective relationship with past 30-day CU. There was no consistent evidence supporting the protective factors resiliency model.

Adolescent Substance Use Prevention: Long-Term Benefits of School Engagement

BACKGROUND

To determine if school engagement is a viable target for early prevention of adolescent substance use, this study investigated whether school engagement in early adolescence (ages 12-14) is a cause of alcohol and cannabis use during middle to late adolescence (ages 15-19).

METHODS

To facilitate causal inference, inverse probability of treatment weights (IPTWs), which are based on estimated probabilities of treatment selection (ie, school engagement), were created based on a robust set of potential confounders. Using the IPTWs, a cumulative link mixed model was fit to examine the impact of school engagement on alcohol and cannabis use among an ethnically diverse sample of adolescents (N = 360).

RESULTS

School engagement was associated with a lower level of alcohol and cannabis use from age 15 to 18. School engagement was not associated with change in alcohol and cannabis use over time, suggesting that school engagement emits its effect early in the developmental course of substance use and offers protection throughout adolescence.

CONCLUSIONS

This study supports a compensatory role of early school engagement in substance use across middle and late adolescence. School engagement is a malleable factor and thus offers an avenue for prevention efforts.

Criminality among Young People With Substance Use Problems in Sweden: A One-Year Follow-Up Study

Swedish drug policy has a strong focus on minor drug violations. This longitudinal study analyses the association between criminality and substance use problems among young people who have received outpatient treatment and risk factors that predict continued problems with criminality. Research on this target group is under development in Sweden, but there are few follow-up studies. The study indicates that about one-quarters of the young people who begin outpatient treatment have been convicted of crimes at 1-year follow-up. Most of them who had been convicted with offences also have ongoing problems with substance use and three-quarters of the young people had been charged with a drug-related offence. More than five risk factors give an elevated risk of continued criminality. Interventions meeting the needs of young people, moving away from the current emphasis on penal law principles, may also contribute to reduced criminality in this target group.

Adolescent smoking, alcohol use, inebriation, and use of narcotics during the Covid-19 pandemic

Background

The aim of the study was to investigate how general family relations, reported changes in family interaction and involvement with peers during the Covid-19 pandemic, and following rules and recommendations during the pandemic relate to adolescent smoking, alcohol use, inebriation, and use of narcotics during Covid-19.

Methods

An online national survey of Swedish adolescents (n = 1818) aged 15–19 years was conducted in June 2020. Hierarchical regression analysis was used to predict adolescents’ reported change in substance use during the pandemic. Person-oriented analyses, were used to identify clusters of participants characterized by similar patterns of substance use following ANOVA analysis with Scheffe post hoc tests testing differences between clusters in terms of family relations, reported changes in family interaction and involvement with peers during the Covid-19 pandemic, and following rules and recommendations during the pandemic.

Results

Higher general family conflict, increased involvement with peers, a strained relationship with parents, and less compliance with rules and restrictions during the pandemic predicted a reported increase in adolescent substance use during this period. The grouping of scores for adolescent smoking, alcohol use, inebriation, and use of narcotics resulted in a six-cluster solution. One cluster (n = 767) either did not use or had decreased use of substances during the Covid-19 pandemic. Five other clusters, thus risk clusters, had retained or increased use of substances during the pandemic. Poor general family relations, increased peer involvement, and difficulties to conform to the rules and restrictions during the covid-19 pandemic were characteristics of risk clusters.

Conclusions

Most of adolescents in our study did not increase their substance use during the pandemic. However, adolescents with poor family relations who turn to peers during stressful times and who have difficulty following the government’s rules and restrictions, are at risk of increased substance use during the pandemic. This is a potential threat both to adolescents themselves and others in their surroundings which is why at-risk adolescents and their families need more attention from public health and social services during this time of crisis.

The Protective Role of Grit against Alcohol and Cannabis Use through Young Adulthood

Introduction: Problematic substance use in young adulthood is consistently related to negative outcomes later in life. Understanding the factors that protect against problematic substance provides opportunities for early preventive intervention. We examine the protective role of grit - passion and perseverance for long-term goals - on substance use through young adulthood, a period of heightening risks for substance use. Methods: In this research, we use cross-lagged panel models and data from the Victoria Healthy Youth Survey (N = 477, 52% female) to test the reciprocal within-time associations and the directional relationships between grit (passion and perseverance) and substance use (cannabis and alcohol) across three assessments (6 years, ages 18-29). All models controlled for sex and SES. Results: Significant findings show negative within-time associations between passions and perseverance and cannabis use at T1 (ages 18-24) and at T2 (ages 20-26), and significant, negative within-time associations between passion and perseverance and alcohol use (heavy episodic drinking) at T1 but not at T2. No significant across-time associations between passion and perseverance and substance use were found. Conclusion: Preventive interventions to enhance passion and perseverance may provide important targets for interventions for young adults to reduce current substance use. However, grit did not have an effect beyond the stability of cannabis use or alcohol use over time, suggesting effects may act by substituting proactive goals for current substance use.

Patterns and correlates of substance use among young adult African American women

Patterns and correlates of substance use among urban African American young women (ages 18-19, n = 459) were examined. Four patterns were identified: no/infrequent alcohol and marijuana use (64.9%); recent alcohol only use (18.2%); recent marijuana only use (7.9%); and recent alcohol and marijuana use (9.0%). Having a recent male sexual partner and a history of sexual coercion were associated with increased odds of marijuana-only and dual use. Greater family support and childhood sexual abuse were associated with increased odds of alcohol-only use. Results suggest that sexual relationships and history of abuse/coercion are important factors in young African American women's substance use.

Long-Term Outcomes for Young People With Substance Use Problems in Outpatient Treatment: Gender-Specific Patterns

This study presents the results of a longitudinal research project focusing on long-term outcomes among young people after initiation of outpatient treatment for substance use problems (SUP) in Sweden. Young people are defined with the age group 13-25 years. A clinical sample of 451 young people (29% girls, median age 17 years) completed a structured interview at baseline and was followed using official records one, two, and 3 years after initiation of treatment. Gender-specific patterns at intake were described and bivariate associations and logistic regressions were calculated to analyse the links between risk factors at treatment start and indications of substance use problems 3 years later. Significantly more boys than girls displayed indications of continued SUP at 3-year follow-up. More specifically, 49% of the boys vs. 35% of the girls were identified through records as still having problems with substance use. Predictive risk factors also displayed gender-specific patterns. Primary drug use frequency and age at intake predicted indications of SUP among boys but not among girls. Placement in foster care/residential homes, depression, and early drug debut had significant predictive value regarding indications of SUP among females but not among males. Girls also displayed a greater psychosocial burden at treatment start, but a more favorable treatment outcome at follow-up. Youths with a heavy risk load at treatment start (i.e., over six risk factors) did not display a greater risk of SUP at 3-year follow-up, although our results suggest that this subgroup has indications of continued problems with mental health. Consequently, future studies should further explore gender-specific treatment pathways for young people with substance use problems. Since women and girls seem to have different risk factors, co-occurring psychiatric problems and more experiences of trauma compared to men, they might need multidimensional and more comprehensive treatment interventions that run over a longer period of time.

A Machine Learning Approach to Identify Predictors of Frequent Vaping and Vulnerable Californian Youth Subgroups

INTRODUCTION

Machine learning presents a unique opportunity to improve electronic cigarette (vaping) monitoring in youth. Here we built a random forest model to predict frequent vaping status among Californian youth and to identify contributing factors and vulnerable populations.

METHODS

In this prospective cohort study, 1,281 ever-vaping twelfth-grade students from metropolitan Los Angeles were surveyed in Fall and in 6-month in Spring. Frequent vaping was measured at the 6-month follow-up as nicotine-containing vaping on 20 or more days in past 30 days. Predictors (n=131) encompassed sociodemographic characteristics, substance use and perceptions, health status, and characteristics of the household, school and neighborhood. A random forest was developed to identify the top ten predictors of frequent vaping and interactions by sociodemographic variables.

RESULTS

Forty participants (3.1%) reported frequent vaping at the follow-up. The random forest outperformed a logistic regression model in prediction (C-Index=0.87 vs. 0.77). Higher past-month nicotine concentration in vape, more daily vaping sessions, and greater nicotine dependence were the top three of the ten most important predictors of frequent vaping. Interactions were found between age and perceived discrimination, and between age and race/ethnicity, as those who were younger than their classmates and either reported experiencing discrimination frequently or identified as Asian or Native American/Pacific Islander were at increased risk of becoming frequent vapers.

CONCLUSIONS

Machine learning can produce models that accurately predict progression of vaping behaviours among youth. The potential association between frequent vaping and perceived discrimination warrants more in-depth analyses to confirm if discrimination constitutes a cause of increased vaping.

Substance use and associated factors among preparatory school students in Kolfe-Keranyo sub-city of Addis Ababa, Ethiopia

Background

Substance abuse is a worldwide problem that primarily affects adolescents, resulting in chronic health complications as well as psychosocial challenges and economic losses. However, the magnitude of the problem and the factors that contribute to it are not well studied in Ethiopia, particularly in the study area. As a result, this study was carried out to determine the prevalence and associated factors of substance use among preparatory school students in the Kolfe-Keraniyo sub-city of Addis Ababa, Ethiopia.

Methodology

An institution-based cross-sectional study of 383 randomly selected preparatory school students in the Kolfe-Keraniyo sub-city was conducted. The data were gathered using a pretested self-administered structured questionnaire. Multivariable binary logistic regression analysis was employed to identify factors associated with substance use based on the adjusted odds ratio (AOR) and 95% confidence interval (CI) with p values less than 0.05.

Result

This study revealed that the lifetime prevalence of substance use among preparatory students in Kolfe-Keraniyo sub-city, Addis Ababa, Ethiopia, was 26.5% (95% CI, 22.2, 30.7%). Specifically, 16% drunk alcohol, 9.6% smoked cigarette, and 9.4% chewed khat. The 16.3% were current users, of which 8.3% were drinkers, 6.4% were smokers, and 5.9% were khat chewers. Substance use was significantly associated with being male (AOR, 3.3; 95% CI, 1.284, 8.613), having alcohol drinking family member (AOR, 4.0; 95% CI, 1.704, 9.196), having khat chewing family member (AOR, 2.87; 95% CI, 1.161, 7.070), poor school substance use controlling rule (AOR, 6.64; 95% CI, 1.863, 23.687), availability of substance retailing shops in residential areas (AOR, 2.9; CI, 1.303, 6.606), strong relationship with parents (AOR, 0.005; 95% CI, 0.001, 0.026), and being member of school mini-media (AOR, 0.177; 95% CI, 0.048, 0.657).

Conclusion

According to the findings of this study, one-quarter of the study participants were substance users. Alcohol, khat, and cigarettes were all commonly used substances. Gender, parent-child relationship, family member substance use history, school substance use controlling rules, school mini-media and pro-social involvement, and the availability of substance retailing shops were all strongly associated with substance use. Strengthening school rules on substance use, controlling substance retailing shops near schools and residential areas, and providing students with health education are all strategies for reducing substance use among students.

Examining risk and protective predictors of substance use among low-income Native Hawaiian and Pacific Islander adolescents

Substance use (SU) among adolescents is a critical public health concern that increases the risk for negative outcomes. Although Asian American (AA) adolescents tend to report low rates of SU, Native Hawaiian and Pacific Islander (NH/PI) adolescents often report significantly higher rates of use. Yet, NH/PI youth are seldom studied as a separate group. Consequently, little is known about the factors involved in SU among NH/PI adolescents and how to prevent it. This prospective study investigated the effect of ecological risk and protective factors at the individual, family, and school levels on SU for NH/PI adolescents. This prospective study utilized longitudinal data from 120 NH/PI adolescents who were7 part of an SU prevention program. Information was collected at two time points-Time 1 and Time 2 (32 weeks later)-and included adolescents' SU behaviors and individual, family, and school factors. The parents of these adolescents also provided data; all information was self-report. Positive academic attitudes at Time 1 were negatively associated with alcohol and other drug (e.g., marijuana) use at Time 2. Specifically, NH/PI adolescents who had more positive attitudes toward their school, peers, and teachers reported less alcohol and other SU. Prevention efforts may be most effective for NH/PI adolescents if addressed within the school context. This may include programs implemented in schools, utilizing teachers as role models, and/or promoting prosocial peer relationships to support positive behaviors. Additional implications are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Protective Factors Against Vaping and Other Tobacco Use

BACKGROUND AND OBJECTIVES

Vaping has gained popularity among adolescents despite negative health consequences. Few studies have focused on factors that may protect against vaping. We sought to determine if future orientation, parental monitoring, school connectedness, and social support are associated with decreased risk of vaping and other forms of tobacco use.

METHODS

Data were obtained via anonymous school-based health behavior surveys among ninth- through 12th-graders in Pittsburgh, PA (n = 2487). Protective factors were assessed through validated Likert scale instruments. The primary outcome was recent (past 30-day) vaping. Additional outcomes included other forms of tobacco use and intention to quit tobacco products. Poisson regression models examined associations between protective factors and vaping and tobacco use outcomes.

RESULTS

Mean age was 15.7 years, 1446 (58.1%) respondents were female, and 671 youth (27.0%) reported recent vaping. Positive future orientation and high parental monitoring were associated with significantly lower prevalence of recent vaping (adjusted prevalence ratio: 0.84 [95% confidence interval: 0.73-0.97] and adjusted prevalence ratio: 0.73 [95% confidence interval: 0.62-0.85], respectively). There were no significant relationships between social support or school connectedness and vaping. All 4 protective factors were inversely associated with other forms of tobacco use. No factors were significantly associated with intent to quit tobacco products.

CONCLUSIONS

Findings reveal significant inverse associations between future orientation, parental monitoring, and vaping but no relationship between protective factors and intent to quit tobacco products. Developing interventions to foster protective factors in youth and their parental supports may inform primary prevention efforts to reduce vaping and other tobacco use.

Social-Ecological Predictors of Opioid Use Among Adolescents With Histories of Substance Use Disorders

Adolescent opioid misuse is a public health crisis, particularly among clinical populations of youth with substance misuse histories. Given the negative and often lethal consequences associated with opioid misuse among adolescents, it is essential to identify the risk and protective factors underlying early opioid misuse to inform targeted prevention efforts. Understanding the role of parental risk and protective factors is particularly paramount during the developmental stage of adolescence. Using a social-ecological framework, this study explored the associations between individual, peer, family, community, and school-level risk and protective factors and opioid use among adolescents with histories of substance use disorders (SUDs). Further, we explored the potential moderating role of poor parental monitoring in the associations between the aforementioned risk and protective factors and adolescent opioid use. Participants included 294 adolescents (M _age = 16 years; 45% female) who were recently discharged from substance use treatment, and their parents (n = 323). Results indicated that lifetime opioid use was significantly more likely among adolescents endorsing antisocial traits and those whose parents reported histories of substance abuse. Additionally, adolescents reporting more perceived availability of substances were significantly more likely to report lifetime opioid use compared to those reporting lower perceived availability of substances. Results did not indicate any significant moderation effects of parental monitoring on any associations between risk factors and lifetime opioid use. Findings generally did not support social-ecological indicators of opioid use in this high-risk population of adolescents, signaling that the social-ecological variables tested may not be salient risk factors among adolescents with SUD histories. We discuss these findings in terms of continuing care options for adolescents with SUD histories that target adolescents' antisocial traits, perceived availability of substances, and parent histories of substance abuse, including practical implications for working with families of adolescents with SUD histories.

Role of Sleep Duration in the Association Between Socioecological Protective Factors and Health Risk Behaviors in Adolescents

OBJECTIVE

The purpose of this study was to examine the associations of sleep duration and socioecological protective factors with patterns of adolescent risk behaviors in Fairfax County, VA-one of the largest public school districts in the United States.

METHODS

A total of 21,360 and 20,330 students in 10th and 12th grades who completed the Youth Risk Behavior Survey were included in this cross-sectional analysis. Sleep duration was measured by self-report of the average number of hours of sleep on a school night. Ten socioecological protective factors included peer-individual, family, school, and community domains. Latent class analysis was used to classify 7 risk behaviors (alcohol use, cigarette use, illicit drug use, inappropriate prescription drug use, risky sexual behavior, deviant behavior, and academic failure) into 4 class memberships (low, some, moderate, and high). Multinomial regression models were adjusted for age, sex, and race.

RESULTS

Adolescents who reported sleeping the recommended 8 to 9 hours were significantly less likely to belong to the class memberships of greater risk behaviors compared with those who reported short and long sleep duration after controlling for age, sex, race, and survey year. There was a significant inverse relationship between the number of socioecological protective factors and risk behaviors for both 10th and 12th graders. Potential risks of age, sex, and race on risk behaviors were observed. No significant interaction between sleep duration and protective factors was found in either grade.

CONCLUSION

This study highlights the significant associations between sleep duration and risk behaviors in adolescents with diverse socioecological protective factors. Prioritization of prevention-focused resources should consider sleep duration in addition to the socioecological protective factors commonly cited in the literature when addressing adolescent risk behaviors.

Factors associated with crack-cocaine early initiation: a Brazilian multicenter study

BACKGROUND

Crack-cocaine dependence is a serious public health issue, related to several psychiatric and psychosocial problems. Crack-cocaine users are usually embedded in a context of great social vulnerability, often associated with violence, poverty, family conflict and easy and early access to alcohol, tobacco and other drugs.

METHODS

This cross-sectional study enrolled a consecutive sample of 577 patients admitted to 20 therapeutic communities located in Southern Brazil, between September 2012 and September 2013. A structured interview assessed life-time exposure to risk and protective factors for drug use, such as parental monitoring in childhood, deviant behaviors and peer pressure.

RESULTS

Presence of family conflict (p = 0.002), maltreatment (p = 0.016), and deviant behavior prior to age 15 in a bivariate analysis predicted an earlier age of crack-cocaine initiation, whereas adolescents experiencing parental monitoring during adolescence started use later (p < 0.001). In the multivariate model, perceptions related to ease of access of illicit drugs (marijuana: p = 0.028, 95% CI = - 3.81, - 0.22; crack-cocaine: p < 0.001, 95% CI = - 7.40, - 4.90), and deviant behavior (threatening someone with a gun: p = 0.028, 95% CI = - 2.57, - 0.14) remained independent predictors of early age of crack-cocaine initiation.

CONCLUSIONS

Early onset of crack-cocaine use seems to be associated with exposure to family conflict, easy access to drugs and deviant behavior. Treatment and preventive programs should take these factors into account when designing and implementing community interventions.

Adolescent Marijuana Dependence: The Role of Social Bonds and Social Learning Theory

Using the 2017 National Survey of Drug Use and Health (NSDUH) data, this research examines the extent to which social bonds and social learning theory predict adolescent marijuana dependence. Full information maximum likelihood (FIML) for logistic regression analyses were conducted in four models to test the competing theories. The results revealed partial support for both theories, such that adolescents with stronger parental bonds and negative definitions of substance use were less likely to be dependent on marijuana, while adolescents who associated with substance using peers were more likely to be dependent on marijuana. The multi-theoretical model suggested that only the social learning theory concepts of differential association and negative definitions were significant theoretical predictors of adolescent marijuana dependence. Additional analyses revealed that first using marijuana at 14 or 15 years old was also significantly related to adolescent marijuana dependence. Implications for future research and risk prevention programs are discussed.

Cannabis use and cannabis use disorder

Cannabis use disorder (CUD) is an underappreciated risk of using cannabis that affects ~10% of the 193 million cannabis users worldwide. The individual and public health burdens are less than those of other forms of drug use, but CUD accounts for a substantial proportion of persons seeking treatment for drug use disorders owing to the high global prevalence of cannabis use. Cognitive behavioural therapy, motivational enhancement therapy and contingency management can substantially reduce cannabis use and cannabis-related problems, but enduring abstinence is not a common outcome. No pharmacotherapies have been approved for cannabis use or CUD, although a number of drug classes (such as cannabinoid agonists) have shown promise and require more rigorous evaluation. Treatment of cannabis use and CUD is often complicated by comorbid mental health and other substance use disorders. The legalization of non-medical cannabis use in some high-income countries may increase the prevalence of CUD by making more potent cannabis products more readily available at a lower price. States that legalize medical and non-medical cannabis use should inform users about the risks of CUD and provide information on how to obtain assistance if they develop cannabis-related mental and/or physical health problems.

Aggressiveness in Adopted and Non-Adopted Teens: The Role of Parenting, Attachment Security, and Gender

The aim of this study was to examine the relationship among aggressiveness, parenting practices, and attachment security in adolescents, assessing maternal and paternal effects separately. Two different subsamples of adolescents between 12 and 16 years old participated in the study (n = 157): 67 adopted adolescents (61.2% girls) and 90 non-adopted adolescents (56.7% girls). Partial and full mediation models were analyzed in multi-group structural equation models (using maximum likelihood estimates), allocating non-adoptive and adoptive adolescents into two different groups. Results showed that whereas acceptance/involvement of each parent predicted attachment security towards the corresponding parental figure, only the father's coercion/imposition predicted aggressiveness, and only attachment security to the mother was a (negative) predictor of adolescent's aggressiveness. The partial mediation model provided the most parsimonious explanation for the data, showing no differences between adopted and non-adopted subsamples and supporting a good model fit for both boys and girls in a multi-group invariance analysis. The implications of these results are discussed in light of the protective effects of care relationships in early adolescence (vs. late adolescence) as well as the differential role of parent figures.

Mental Health, Academic Engagement, and Youths' Nonmedical Use of Stimulants: A Latent Profile Analysis

BACKGROUND:

Nonmedical prescription stimulant (NPS) use is a growing problem in Europe. Poor mental health and lack of academic engagement are potent sources of risk for substance use. Studies suggest that considerable heterogeneity may characterize the risk profiles of NPS users. To understand better the potential profiles of risk that characterize NPS users, we conducted a latent profile analysis (LPA) to document subgroups of users based on their mental health and academic engagement.

METHODS:

A nationally representative, cross sectional survey of Icelandic youth was analyzed. The sample included 584 (5% of the sample) older adolescent students participating in a national study in Iceland who reported lifetime NPS use.

RESULTS:

Three subgroups of NPS users emerged from our analyses. The largest subgroup (43.1%) we labeled mentally healthy achievers; youth who appear to be academically motivated and have few if any mental health concerns. The second largest group (40.4%), low achievers, resembled a typical profile for drug users in that they reported low or modest academic engagement and moderate levels of mental health concerns. The third group, anxious achievers (16.5%) appears to represent youth who felt academics were very important, had moderate study motivation, and also reported elevated mental health concerns, especially anxiety.

CONCLUSIONS:

LPA revealed considerable heterogeneity among these users. Group membership suggests distinct approaches to prevention to address heterogeneity in motivations for NPS use.

Similar countries, similar factors? Studying the decline of heavy episodic drinking in adolescents in Finland, Norway and Sweden

AIM

To (i) examine several factors associated with trends in heavy episodic drinking (HED) in Finland, Norway and Sweden, (ii) investigate similarities in these associations across the countries and (iii) analyse the contribution of these factors to the trend in HED and the differences across the countries.

DESIGN AND SETTING

Observational study using five waves of the European School Survey Project on Alcohol and Other Drugs (ESPAD) from Finland, Norway and Sweden between 1999 and 2015.

PARTICIPANTS

A total of 18 128 male and 19 121 female 15- to 16-year-old students.

MEASUREMENTS

Monthly HED, perceived access to alcohol, truancy, parental control, leisure time activities and daily smoking. The Cochran-Armitage test was used to examine linear time trends in HED. Logit regression models using the Karlson-Holm-Breen (KHB) method were fitted for each country separately, including all the independent variables together with time and adjusted for family status, parental education and gender.

FINDINGS

In Finland, Norway and Sweden, perceived access to alcohol, truancy and daily smoking decreased significantly between 1999 and 2015 whereas risk perceptions, parental control and participation in sports increased in the same period. The confounding percentage of all the independent variables related to the trend in HED was 48.8%, 68.9% and 36.7% for Finland, Norway and Sweden, respectively. Decline in daily smoking (P < 0.001) and perceived access to alcohol (P < 0.001) were positively and increase in parental control (P < 0.001) negatively associated with the decline in HED in all three countries. Changes in truancy, going out with friends, and engaging in sports and other hobbies had little or no impact on the decline in HED or displayed no consistent results across the countries.

CONCLUSIONS

The decline in adolescent heavy episodic drinking in Finland, Norway and Sweden between 1999 and 2015 appears to be associated with a decline in adolescent daily smoking and perceived access to alcohol and an increase in parental control.

Binge Eating and Binge Drinking: A Two-Way Road? An Integrative Review

Unhealthy diet and alcohol are serious health problems, especially in adolescents and young adults. "Binge" is defined as the excessive and uncontrolled consumption of food (binge eating) and alcohol (binge drinking). Both behaviors are frequent among young people and have a highly negative impact on health and quality of life. Several studies have explored the causes and risk factors of both behaviors, and the evidence concludes that there is a relationship between the two behaviors. In addition, some research postulates that binge eating is a precipitating factor in the onset and escalation of excessive alcohol consumption, while other studies suggest that alcohol consumption leads to excessive and uncontrollable food consumption. Given that no review has yet been published regarding the directionality between the two behaviors, we have set out to provide an upto- date overview of binge eating and binge drinking problems, analyzing their commonalities and differences, and their uni- and bidirectional associations. In addition, we explore the reasons why young people tend to engage in both behaviors and consider directions for future research and clinical implications.

Psychosocial and socio-environmental factors associated with adolescents' tobacco and other substance use in Bangladesh

BACKGROUND

Tobacco, alcohol, and marijuana are the top three substances used by adolescents. The adverse health effects of these three substances are well documented in epidemiological literature, yet little is known about the substance use and associated factors among adolescents in Bangladesh. This study examines the risk factors for tobacco and other substances use among school-going adolescents in Bangladesh.

METHODS

We analyzed data from the 2014 Bangladesh Global School-based Student Health Survey (GSHS) of adolescents aged 13-17 years. We used two outcome measures: tobacco use (TU) and other substance use (SU; alcohol and/or marijuana). We examined a set of reported psychosocial and socio-environmental adverse events as risk factors. Logistic regression analyses were used to identify associations.

RESULTS

The prevalence of TU and other SU among school-going adolescents was 9.6% and 2.3%, respectively. The likelihood of TU and other SU was higher among adolescents who reported being bullied (TU: adjusted odd ratio [AOR]: 1.93; 95% confidence interval [CI]: 1.24-3.00; and other SU: AOR: 3.43; 95% CI: 1.46-7.99) and having sexual history (TU: AOR: 19.38; 95% CI: 12.43-30.21; and other SU: AOR: 5.34; 95% CI: 2.17-13.29). Moreover, anxiety-related sleep loss was associated with adolescents' TU (AOR: 2.41; 95% CI: 1.02-5.82) whereas the likelihood of other SU (AOR: 3.27; 95% CI: 1.14-9.44) was higher among lonely adolescents. Experience of adverse socio-environmental factors, such as parental substance use (TU: AOR: 7.81; 95% CI: 5.08-12.01), poor monitoring (TU: AOR: 1.96; 95% CI: 1.16-3.31) and poor understanding (TU: AOR: 2.22; 95% CI: 1.36-3.65), and lack of peer support (TU: AOR: 3.13; 95% CI: 1.84-5.31; and other SU: AOR: 2.45; 95% CI: 1.02-5.91), and truancy (other SU: AOR: 4.29; 95% CI: 1.81-10.12) were also positively associated with TU and/or other SU. Additionally, higher odds of tobacco use were observed among adolescents who reported 1 (AOR: 4.36 times; 95% CI: 1.34-14.24), 2 (AOR: 8.69 95% CI: 1.67-28.23), and ≥3 (AOR: 17.46; 95% CI: 6.20-49.23) adverse psychosocial experiences than who did not report any psychosocial events.

CONCLUSIONS

Tobacco and other substance use among school-going adolescents are prevalent in Bangladesh. Several psychosocial and socio-environmental events are associated with TU and other SU, which should be incorporated into adolescent substance use and health promotion programs.

Bullying and Substance Use in Early Adolescence: Investigating the Longitudinal and Reciprocal Effects Over 3 Years Using the Random Intercept Cross-Lagged Panel Model

Bullying and substance use among adolescents have been increasingly studied in the field of developmental psychology, but research to date has primarily investigated the cross-sectional relationship and, to a lesser extent, the long-term impact of bullying on substance use. Grounded in the General Theory of Crime, this study focused on the longitudinal reciprocal relationships between bullying and substance use (i.e., smoking and alcohol consumption) during early to mid-adolescence, which is a critical developmental phase. We aimed to investigate the hypothesis of a reinforcing downward spiral at the within-person level. Moreover, we intended to examine gender differences in the expected longitudinal relationships. Our analyses are based on self-report data for bullying and substance use collected from 1,495 adolescents (746 males; M age at T 1 = 12.42, SD = 0.58) at three waves between 2017 and 2019. We applied the random intercept cross-lagged panel model to separate within-person from between-person effects. At the between-person level, the mutual association between bullying and substance use, previously demonstrated in cross-sectional studies, was confirmed. At the within-person level, results provide evidence of a significant age-dependent change in bullying and substance use from 13 to 14 years old, where the significant increase in bullying could be attributed to females but not to males. We also found a gender-independent significant positive effect of bullying at 12 years old on substance use at 13 years, but not vice versa. Thus, the hypothesis of a reinforcing downward spiral, shown by significant positive reciprocal effects, did not find support. According to the General Theory of Crime, our findings underline that bullying can be considered a context-related factor inasmuch as it pushes adolescents to smoke and drink, which are both expressions of low levels of self-control, which need to be considered in intervention programs to effectively prevent unhealthy and risky behaviors in adolescence.

The role of negative emotional reactivity and neighborhood factors in predicting marijuana use during early adolescence

INTRODUCTION

Negative emotional reactivity and the neighborhood environment have been individually associated with marijuana use outcomes; however, less is known about whether neighborhood factors differentiate the association between negative emotional reactivity and marijuana use. The present study examined whether neighborhood risk (i.e., neighborhood problems) and protective factors (i.e., neighborhood social cohesion) moderated the relation between negative emotional reactivity and marijuana use during early adolescence.

METHODS

Participants were 775 adolescents (M = 10.95 ± 0.88 years; 69% male; 76% Caucasian), who reported on their past month frequency of marijuana use at Time 1 (when adolescents were 10-12 years old) and Time 2 (when adolescents were 12-14 years old). Mothers reported on neighborhood problems and neighborhood social cohesion at Time 1. Youth reported on their negative emotional reactivity at Time 2.

RESULTS

Negative binomial regression analyses indicated that neighborhood problems moderated the relationship between negative emotional reactivity and marijuana use. In particular, in the context of low neighborhood problems, individuals with lower negative emotional reactivity were at attenuated risk for marijuana use compared to individuals higher in negative emotional reactivity. In the context of high neighborhood problems, individuals were at heightened risk for marijuana consumption regardless of their negative emotional reactivity levels.

CONCLUSIONS

Findings suggest that individual-level factors alone do not sufficiently account for early marijuana use and that neighborhood problems play a role in risk for or abstention from using marijuana during early adolescence. Implications for prevention and intervention for marijuana use during adolescence are discussed.

The Mediating Role of Positive and Negative Affect in the Association of Perceptions of Parenting Styles with Resilience among Adolescents with Addicted Parents

Objective: This study aimed to investigate the mediating role of positive and negative affect in the association of perceptions of parental involvement, autonomy support, and warmth with resilience among Adolescents with Addicted Parents. Method : In this descriptive-correlational study, 63 Adolescents of Addicted Parents studying in Zahak and Hirman, located in Sistan and Baluchestan Province in Iran, were selected using convenience sampling method. The participants completed the questionnaires on perceptions of parenting styles, resilience, and positive and negative affect. Data were analyzed via the correlation coefficient and path analysis. Results: The results showed that the adolescents' perceived parenting styles were directly and significantly related to positive affect and resilience (P < 0.01). Moreover, the results of the path analysis indicated that mediated by positive affect, the adolescents' perceived parenting styles predicted resilience indirectly (P < 0.01). Conclusion: Given the results of this study, perceived parenting styles can directly and indirectly predict resilience. It can be concluded that adolescents' perceived parenting styles can enhance resilience among them through promoting positive affect.

A review of psychosocial factors linked to adolescent substance use

PURPOSE

Informed by ecological theories and models of influence, this review discusses various psychosocial risk and protective factors that contribute to adolescent substance use behavior. Given typical patterns of substance use initiation during this developmental period, an emphasis is placed on alcohol, cigarette, and marijuana use.

FINDINGS

Consistent with bioecological theories, peers and parents tend to have the strongest effect on adolescent substance use behavior. Influences can be both direct, such as offers and availability to use substances, as well as indirect influences, such as the perception of substance use approval. Schools and neighborhoods also contribute to adolescent substance use behavior, but this effect is often less direct. Moreover, the effect of neighborhoods on adolescent behavior reflects both structural components (e.g., neighborhood racial composition, teacher-student ratios) in addition to social process (e.g., neighborhood social cohesion, school connectedness). A review of parallel studies conducted with animals is also provided.

SUMMARY

Adolescent substance use behavior does not occur in a vacuum. Investigations must encompass the relevant social ecologies that affect adolescent behavior, including family, peer, school, and neighborhood contexts to provide a more complete understanding of substance use etiology.
