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

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

Teachers' delivery skills and substance use prevention program outcomes: the moderating role of students' need for cognition and impulse decision making

The purpose of this study was to extend the literature in both substance use implementation and persuasive health communication by examining the extent to which students' need for cognition and impulsive decision-making moderated the relationship between teachers' classroom communication behavior and program outcomes in an evidence-based middle school substance use prevention curriculum. Participants included 48 teachers and their respective 7th grade students who participated in a randomized trial testing the effectiveness of personal coaching as a means to improve the quality with which teachers implemented the All Stars curriculum. Need for cognition and impulse decision-making were both associated with positive changes in lifestyle incongruence and commitments to not use substances for students whose teachers displayed greater interactive teaching. Further, need for cognition was associated with lower alcohol use rates while impulse decision making related to lower rates of marijuana use in classes with interactive teaching.     

Patterns of alcohol use and marijuana use among students at 2- and 4-year institutions

Objective: The objective of this study was to understand substance use patterns of alcohol, marijuana, and simultaneous alcohol and marijuana (SAM) use among 2- and 4-year college students. Participants: Participants were 526 young adults aged 18–23 (n?=?355 4-year students; n?=?171 2-year students) recruited from February 2015 to January 2016 who were participating in a larger longitudinal study. Methods: Latent class analysis (LCA) was used to identify past-month classes of alcohol, marijuana, and SAM use. Results: Among both 2- and 4-year students, a four-class solution yielded the best-fitting model, with 2-year classes tending to include greater marijuana use and less alcohol use and 4-year classes tending to include heavy alcohol use. Demographic characteristics were largely similar across classes. Conclusions: Classes of alcohol, marijuana, and SAM use differed by education status. Screening and prevention efforts for 4-year students may need to be tailored for the needs of 2-year students.     

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

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

A Longitudinal Analysis of Adolescent Substance Use and School Motivation Among African American Youth

Cross‐sectional research has shown a link between adolescent substance use and educational motivation. The purpose of the current study was to examine this link in a longitudinal sample of African American youth. The study examined the interrelationships between alcohol and both marijuana use and school motivation over the high school years and their effect on graduation in 681 African American adolescents (50.8% female). School motivation was shown to relate to subsequent alcohol use throughout high school and marijuana use early in high school. School motivation did not affect graduation status, but alcohol and marijuana use were related to a lower likelihood of graduating from high school. Some gender differences and differences among those who had tried alcohol or marijuana at the first wave as opposed to those who had not tried each substance were found. The findings support a systems model where school experiences can affect substance use, which, in turn, can affect the completion of high school.     

Internalizing Symptoms,Peer Substance Use,and Substance Use Initiation

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

Psychosocial correlates of recreational ecstasy use among college students

College students' ecstasy (MDMA) use increased significantly in recent years, yet little is known about these students. In this study, the authors used the Center for Alcohol and Other Drug Studies (CORE) survey to compare 29 college students who had used ecstasy and other illicit drugs with 90 students who had used marijuana and no other illicit drugs. They noted differences in age, frequency of alcohol and marijuana use, average age of onset of marijuana use, frequency of negative consequences associated with substance use, perceptions of peer norms' drug use, perceived peer acceptance of substance use, and risk perception of substance use. When they entered polysubstance use as a covariate, many of these correlates became nonsignificant. The authors suggest that college ecstasy initiators may be a cohort of marijuana users who tend to engage in multiple risk-taking behaviors. This study serves as a preliminary effort to better understand college students who use ecstasy recreationally.     

Alcohol and drug use of inter-city versus rural school age children

The purpose of this study of seventy-nine children was to determine: 1) the prevalence and type of substance use in inter-city and rural eight to twelve-year-old children; and 2) the relationships between child substance use, self-esteem, peer substance use, and family climate. The conceptual framework for the study was a modification of Kumpfer and Turner's Social Ecology Model (1991). Nineteen percent of the children had used alcohol or drugs. Thirty-three percent of the children acknowledged having friends who used substances. Inter-city children reported more alcohol and marijuana use, while the rural children reported more use of inhalants. The responses of both inter-city and rural children also indicated that there were problems with substance use and family violence in the home. Self-esteem and affiliation with drug using peers were significantly correlated with substance use of the child.     

Patterns of Alcohol and Marijuana Use at School

The problem of adolescent substance use has been examined extensively. Beyond simple prevalence estimates, however, little research has been conducted on substance use in the school context. The present investigation was an in‐depth study of students' attitudes and behaviors regarding alcohol and marijuana use during the school day. Based on a representative sample of 1123 high school students, this study assessed the frequency of alcohol and marijuana use at school among demographic subgroups, the accessibility of drugs in school, and students' perceived consequences of being caught using drugs in school. The results showed that male and Hispanic students had higher levels of drug use at school than female and white students, respectively; that school drug use increased with age, and that alcohol and marijuana were easily obtained and used on school grounds. A large percentage of students were not aware of the specific actions taken in their schools to punish drug use. The need for additional research on school‐related drug use is emphasized.     

Unhealthy behavior clustering and mental health status in United States college students

Abstract

Objective: Examine the association of health risk behavior clusters with mental health status among US college students. Participants: 105,781?US college students who completed the Spring 2011 National College Health Assessment. Methods: We utilized the latent class analysis to determine clustering of health risk behaviors (alcohol binge drinking, cigarette/marijuana use, insufficient physical activity, and fruit/vegetable consumption), and chi-square and ANOVA analyses to examine associations between the class membership and mental health (mental health diagnoses, psychological symptoms, and self-injurious thoughts/behaviors). Results: Three classes were identified with differing rates of binge drinking, substance use, and insufficient physical activity but similar rates of insufficient fruit/vegetable consumption. Students classified with the highest rates of binge drinking and cigarette/marijuana use had the highest rates across all mental health variables compared to other classes. Conclusions: Students who reported engaging in multiple health risk behaviors, especially high alcohol and cigarette/marijuana use, were also more likely to report poorer mental health.     

Neighborhood Effects on Youth Substance Use in a Southwestern City

This study examines neighborhood influences on alcohol, cigarette and marijuana use among a predominantly Latino middle school sample. Drawing on theories of immigrant adaptation and segmented assimilation, we test whether neighborhood immigrant, ethnic, and socioeconomic composition, violent crime, residential instability, and family structure have differential effects on substance use among youth from different ethnic and acculturation backgrounds. Data are drawn from self-reports from 3,721 7(th) grade students attending 35 Phoenix, Arizona middle schools. Analysis was restricted to the two largest ethnic groups, Latino students of Mexican heritage and non-Hispanic Whites. After adjusting for individual-level characteristics and school- level random effects, only one neighborhood effect was found for the sample overall, an undesirable impact of neighborhood residential instability on recent cigarette use. Sub-group analyses by individual ethnicity and acculturation showed more patterned neighborhood effects. Living in neighborhoods with high proportions of recent immigrants was protective against alcohol, cigarette, and marijuana use for Latino students at different acculturation levels, while living in predominantly Mexican heritage neighborhoods (mostly non-immigrants) was a risk factor for alcohol and marijuana use for less acculturated Latinos. There were scattered effects of neighborhood poverty and crime, which predicted more cigarette and alcohol use, respectively, but only among more acculturated Latinos. Inconsistent effects confined to bilingual and more acculturated Latinos were found for the neighborhood's proportion of single mother families and its residential instability. No neighborhood effects emerged for non-Hispanic White students. Results suggested that disadvantaged neighborhoods increase substance use among some ethnic minority youth, but immigrant enclaves appear to provide countervailing protections.     

ADHD,depression, and substance abuse risk among beginning college students

Abstract

Objective: This study examined differences in substance use, depression, and academic functioning among ADHD and non-ADHD college students. Participants: Included 1,748 students (ages 18–25; women 68.4%; Caucasian 71.3%) with and without history of ADHD. Methods: We assessed the relationship of ADHD to substance use variables, controlling for depressive symptoms and examined relationships with GPA. Results: ADHD students were more likely to have engaged in frequent alcohol use, binge drinking, regular marijuana use and to have used other drugs in the last year. They reported higher depression symptoms than non-ADHD students, although substance abuse risk remained high even when controlling for depressive symptoms. ADHD students had lower overall GPA than those without ADHD. However, this difference was no longer significant when controlling for depression and marijuana use. Conclusions: College campuses should consider programing aimed at identifying ADHD students at risk for developing substance abuse problems and emotional difficulties.     

Substance use and vulnerability to sexual and physical aggression: a longitudinal study of young adults

Using data from 2,170 individuals who participated in Waves 8 (age 23) and 9 (age 29) of a multiyear panel study, this study examined whether alcohol and marijuana use in young adulthood increase one's risk for experiencing subsequent sexual or physical assault victimization, whether victims' own violent behavior or involvement in the sale of drugs explain any effects of substance use on victimization, and whether these associations differ by gender. Controlling for prior victimization, we found that marijuana use, but not alcohol use, predicted women's and men's subsequent sexual victimization and men's subsequent physical assault victimization, and that heavy alcohol use, but not marijuana use, predicted women's subsequent physical assault victimization. Whereas the links from marijuana use to victimization were explained by users' own violent behavior, the link from alcohol use to women's physical assault victimization was not.     

Benefits to Children Who Participate in Family Therapy with their Substance‐Using Mother

It is rare that family members other than the identified patient are followed over time in studies of therapy effectiveness. Family therapy is believed to be effective because it targets processes within the system that maintain symptoms. If these processes are changed, then all family members can benefit. Using a sample of 183 mother–child dyads from a study comparing family therapy for adult substance use versus an attention control, change in child's substance use (tobacco, alcohol, and marijuana) was estimated. Children who participated in family therapy with their mothers showed greater decreases in alcohol and tobacco use and were less likely to begin using compared to children whose mothers participated in the attention control condition.     

What if you caught them using? Prospective teachers' beliefs about responding to student substance use

This survey research examined how prospective teachers' (N=384) beliefs about the nature of adolescence, their substance use, and their preparedness for dealing with substance use situations are linked to perceptions of how they would respond to students' possession or use of cigarettes, alcohol, and marijuana at school. Results suggested that prospective teachers are not prepared for these situations. Feeling prepared, perceiving that few adolescents engage in problem behavior, and low personal substance use were associated with more responses to substance use situations. Women were more likely than men to think they would respond to adolescent substance use yet they felt less prepared. Males who used alcohol, cigarettes, or marijuana recently were the least likely to perceive that they would respond to adolescents using substances at school.     

Cigarette,alcohol, and marijuana use among adolescents in foster family homes

Data from a cross-sectional study conducted in a random sample of children who were placed in foster family homes were used to examine the prevalence and associated factors of substance use (i.e., cigarette, alcohol, and marijuana), and to explore if adolescents in foster family homes had different rates of substance use than those in the general population matched on age, gender and race/ethnicity. Logistic regression models were used to determine factors associated with substance use and McNemar tests were used to compare prevalence rates of substance use. Substance use was common among adolescents in foster family homes. A higher number of placement settings were significantly associated with current cigarette use (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.09–1.60), and being placed in special study homes (i.e., fictive kin) was significantly associated with current marijuana use (OR, 6.43; 95% CI, 1.40–29.52). Compared to adolescents in the general population, those in foster family homes had lower rates of current alcohol (9.1% vs. 38.3%, p < 0.0001) and marijuana (13.6% vs. 29.7%, p = 0.005) use. No significant difference was observed for current cigarette use (18.2% vs. 11.5%, p = 0.08). More research is needed to confirm the lower rate of current substance use in foster family homes than those matched in the general population, and to explore why adolescents in special study homes were more vulnerable to marijuana use.     

Associations of Alcohol and Marijuana Use With Condom Use Among Young Adults: The Moderating Role of Partner Type

This study used multiple levels of analysis to examine associations of alcohol and marijuana (AM) use with condom use, including the moderating role of partner type, in a general sample of 754 sexually active young adults (mean age = 18.6, SD = 0.63; 77% non-White). Multivariable models examined associations over the past 30 days (global) and at the most recent sexual event (event specific). Over the past 30 days, participants who had a recent casual partner and used both substances reported a higher proportion of condom-protected sexual events during this period compared to AM nonusers, whereas those who had a recent steady partner and used alcohol, marijuana, or both substances reported a lower proportion of condom-protected sexual events compared to AM nonusers. At the most recent sexual event, participants who used both substances were four times more likely than AM nonusers to have condom-protected sex if the event involved a casual partner; however, there were no significant associations if the event involved a steady partner. Marijuana use, particularly combined with alcohol use, deserves greater attention in the context of condom use. Future research should consider different levels of analysis and partner types to fully understand these complex associations.     

Long-term impact of a district-wide school/community-based substance abuse prevention initiative on gateway drug use

This study examined long-term effects of a school/family/community substance abuse prevention partnership intervention lead by a Midwestern school district. Previous findings suggested that the program contributed to decreased tobacco and marijuana, but not alcohol, use prior to and after implementation between 1987 and 1991. The current study examined 8th-12th grade student drug use prevalence data from 1991 and 2003 to determine whether previous program effects were sustained. With one exception, reported lifetime and monthly cigarette use decreased below 1991 levels for all grades. Lifetime and monthly alcohol use decreased below 1991 levels for most grades, a result not previously detected. While still below national rates, reported lifetime use of marijuana increased for all grades over time. The intervention was effective in reducing cigarette and alcohol use over time and in suppressing marijuana use levels below national rates; however, these gains tended to erode in later high school grades.     

Measurement of risk and protective factors for drug use and anti-social behavior among high school students in South Africa

The study sought to examine, for South African adolescents: 1) the reliability of sub-scales of the Communities that Care Youth Survey (CTC Youth Survey) of risk and protective factors for drug use and anti-social behavior; and 2) the extent to which tobacco, alcohol and marijuana use can be predicted from community, family, school, and peer-individual factors based on sub-scales of the CTC Youth Survey. On two occasions, 92 male and 31 female, Grade 8 and 11 students completed measures concerning: 1) their past month tobacco, alcohol and marijuana use; and 2) various community, family, school, and peer-individual factors. Cronbach alpha coefficients of sub-scales of the questionnaire ranged between .60 and .94. Kappa values were at least moderate (above .40) on 19 sub-scales, and on the remaining sub-scales observed agreement levels ranged between .49 and .94. Each domain predicted tobacco, alcohol, and marijuana use. Multiple logistic regression analyses revealed that alcohol use was most strongly accounted for by the peer domain, tobacco use by the school domain, and marijuana use by the peer and community domains. The findings support use of the CTC Youth Survey, with slight revisions, among South African high school students.     

A multivariate analysis of adverse childhood experiences and health behaviors and outcomes among college students

Objective: This study investigated associations between adverse childhood experiences (ACE) prior to age 18 years and multiple health behaviors (eg, cigarette and other substance use) and outcomes (eg, obesity, depression) for a large college sample. Participants: 2,969 college students from seven universities in the state of Georgia were included in the analysis. Methods: Web-based surveys were completed by students (45–60 minutes) during the spring semester, 2015. Results: Findings indicate that more ACEs are associated with higher levels of depressive symptoms, ADHD symptoms, cigarette use, alcohol use, marijuana use, and BMI, in addition to lower levels of fruit and vegetable intake, and sleep. Conclusion: ACEs may carry forward in the lifespan to influence a range of unhealthy outcomes among college students. College intervention programs may benefit by recognizing the pervasiveness of ACEs and their associations with health behaviors and outcomes, and include interventions across more than one health behavior.
