RESUMO
BACKGROUND: While research has assessed correlates of marijuana use, there has been less focus on predictors of differing levels of changes in use during young adulthood, a critical period for use/escalation. OBJECTIVES: We examined changes in marijuana use and related sociocontextual predictors (e.g., earlier-onset substance use, parental use, college type). METHODS: Using data from Georgia college students (ages 18-25 years) in a 2-year, 6-wave longitudinal study (64.6% female, 63.4% White), 2-part random-effects modeling examined use at any assessment and number of days used. RESULTS: Predictors of use status at any assessment included being male (OR = 1.87, 95%CI = [1.28-2.73]), Black (OR = 1.91, 95%CI = [1.15-3.19]), earlier-onset marijuana (OR = 2.63, 95%CI = [1.70-4.06]), cigarette (OR = 2.04, 95%CI = [1.19-3.48]), and alcohol users (OR = 1.49, 95%CI = 1.00-2.22]), parental tobacco (OR = 2.14, 95%CI = [1.18-3.86]) and/or alcohol use (OR = 1.55, 95%CI = [1.09-2.20]), and attending private (vs. public) institutions (OR = 1.68, 95%CI = [1.10-2.59]). Predictors of lower likelihood of use over time included being male (OR = 0.87, 95%CI = [0.77-0.98]), earlier-onset cigarette use (OR = 0.82, 95%CI = [0.68-0.98]), parental alcohol use (OR = 0.86, 95%CI = [0.77-0.97]), and private institution students (OR = 1.17, 95%CI = [1.02-1.34]). Predictors of more days used at baseline included being male (OR = 1.77, 95%CI = [1.40-2.23]), Black (OR = 1.42, 95%CI = [1.04-1.93]), earlier-onset marijuana (OR = 2.32, 95%CI = [1.78-3.01]) and alcohol users (OR = 1.29, 95%CI = [1.01-1.66]), and parental tobacco use (OR = 1.90, 95%CI = [1.32-2.73]). Predictors of fewer days used over time included being older (OR = 0.98, 95%CI = [0.97-1.00]), parental tobacco use (OR = 0.86, 95%CI = [0.78-0.95]), and attending private institutions (OR = 0.89, 95%CI = [0.83-0.93]). CONCLUSIONS: Intervention efforts can be informed by current findings that correlates of baseline use (e.g., being male, attending private institutions) also predicted less use over time, and one's earlier use and parents' use of various substances impacted young adult use.

African American adolescents use marijuana at higher rates and may be more vulnerable to psychosocial risk factors for marijuana use, including depression, post-traumatic stress, and having substance-using peers, compared to Caucasian adolescents. Little is known about how these factors contribute to African American adolescents' motives for marijuana use. This study examined the roles of depressive and post-traumatic stress symptoms and substance-using peers on marijuana use motives among African American adolescents and emerging adults and whether these motives predicted marijuana use. Findings suggest that identifying motives for marijuana use may help improve approaches to reduce use among this population.

BACKGROUND: Literature in the West suggested that bisexual men have a higher smoking rate compared to gay men. Data on patterns of smoking among gay and bisexual men are limited in Eastern Asian countries like China. This study examined the cigarette smoking prevalence for gay versus bisexual men in China and their unique minority stress - smoking pathways. METHODS: Between September 2017 and November 2018, we surveyed a convenience sample of 538 gay men and 138 bisexual men recruited from local sexual minority organizations in four metropolitan cities in China (i.e., Beijing, Wuhan, Nanchang, and Changsha). Measures included sexual orientation, sociodemographics, theory-based minority stressors, depressive symptoms, and past 30-day cigarette smoking. Two-group (gay men vs. bisexual men) structural equation modeling (SEM) was used to test possible distinct mechanisms between theory-based stressors, depressive symptoms, and cigarette smoking among gay men and bisexual men, respectively. RESULTS: The mean age of participants was 26.51 (SD = 8.41) years old and 76.3% of them had at least a college degree. Bisexual men reported a higher rate of cigarette smoking compared to gay men (39.9% vs. 27.3%). Two-group SEM indicated that the pathways for cigarette smoking were not different between gay and bisexual men. Higher rejection anticipation was associated with greater depressive symptoms (standardized ß = 0.32, p < .001), and depressive symptoms were not associated with cigarette smoking. CONCLUSIONS: Minority stress, specifically rejection anticipation, may be critical considerations in addressing depressive symptoms, but not smoking, among both gay and bisexual men in China.

BACKGROUND: The purpose of this study was to evaluate intraindividual variation in "maturing out" of alcohol use by using latent class growth trajectories of alcohol use from adolescence (age 17 years) through young adulthood (age 33 years). We also modeled trajectory group differences with regard to concurrent, age-relevant domains of substance use, health (e.g., physical health rating, sleep problems), interpersonal functioning (e.g., conflict with partner), and occupational functioning (e.g., intrinsic motivation). METHODS: Growth mixture modeling was used with a sample of 1,004 adolescents/young adults, and 3 trajectory groups were identified as follows: (i) a Normative Use group (n = 646) with low alcohol use remaining stable from adolescence to young adulthood; (ii) a Moderate Increase group (n = 300) with moderate alcohol use increasing slowly from adolescence to emergent adulthood (age 23 years) and then decreasing slightly from emergent adulthood to young adulthood (age 33 years); and (iii) a High Increase group (n = 58) with a high, increasing pattern of alcohol use from adolescence to emergent adulthood and then a small decrease in use from emergent adulthood to young adulthood. RESULTS: At age 33 years, trajectory groups differed, with High and Moderate Increase groups differing significantly from the Normative Use group in current alcohol and other substance use and other risk factors (e.g., friends' alcohol use). Furthermore, the High and Moderate Increase groups differed from the Normative Use group on indicators of health (poorer sleep and more sleep problems), social functioning (higher partner and work-family conflict), and occupational functioning (lower intrinsic work motivation). CONCLUSIONS: These findings suggest that trajectory group membership in alcohol use from adolescence to young adulthood is associated with the domains of substance use, health, and social and occupational functioning. Furthermore, the findings suggest that maturing out applies primarily to a subset of those individuals at moderate to higher levels of alcohol use.

INTRODUCTION: Research is needed to examine trajectories of tobacco use beyond cigarette smoking, particularly during emerging middle young adulthood, and to identify distinct multilevel influences of use trajectories. AIMS AND METHODS: We examined (1) tobacco use trajectories over a 2-year period among 2592 young adult college students in a longitudinal cohort study and (2) predictors of these trajectories using variables from a socioecological framework, including intrapersonal-level factors (eg, sociodemographics, psychosocial factors [eg, adverse childhood experiences, depressive symptoms, and attention-deficit hyperactivity disorder symptoms], early-onset substance use), interpersonal factors (eg, social support, parental substance use), and community-level factors (eg, college type, rural vs. urban). RESULTS: About 64.5% were female and 65.0% were white. From age 18 to 26, 27%-31% of participants reported past 30-day use of any tobacco product. We identified four trajectory classes: Abstainers/Dabblers who never or infrequently used (89.2%); Adult users who began using frequently around age 20 and continued thereafter (5.9%); College Smokers who began using before 19 but ceased use around 25 (2.5%); and Teenage users who used during their teenage years but ceased use by 22 (1.9%). Multinomial regression showed that, compared to Abstainers/Dabblers, significant predictors (p < .05) of being (1) Adult users included being male, earlier onset marijuana use, attending public universities or technical colleges (vs. private universities), and living in urban areas; (2) College users included being male, earlier onset marijuana use, and parental alcohol or marijuana use; and (3) Teenage users included only earlier onset marijuana use. CONCLUSION: Distinct prevention and intervention efforts may be needed to address the trajectories identified. IMPLICATIONS: Among young adult college students, the largest proportion of tobacco users demonstrate the risk of continued and/or progression of tobacco use beyond college. In addition, specific factors, particularly sex, earlier onset marijuana use, parental use of alcohol and marijuana, and contextual factors such as college setting (type of school, rural vs. urban) may influence tobacco use outcomes. As such, prevention and cessation intervention strategies are needed to address multilevel influences.

The aim of this study was to describe age-related changes in sexual risk and substance use using existing data from three HIV/sexually transmitted infection (STI) prevention trials conducted in Atlanta, Georgia, that enrolled young African American women. We used two novel analysis methods: integrative data analysis (IDA) and time-varying effect models (TVEM). Each trial collected self-reported behavioral data and vaginal swab specimens assayed for chlamydia, gonorrhea, and trichomonas. Baseline data from all participants and follow-up data from participants not randomized to an active intervention arm were integrated in a pooled dataset using an IDA approach. The pooled dataset included observations for 1974 individuals, aged 14-25 years for behavioral outcomes and 16-25 years for STI outcomes. We used TVEM to model age-related changes in sexual risk and substance use behaviors and STI acquisition, adjusting for trial as a fixed effect. Coital frequency and condomless sex increased through the early 20s while multiple partnerships remained fairly steady. Alcohol use and cigarette smoking increased through about age 24 years before declining. Marijuana use peaked at age 16-17 years and thereafter generally declined. STI acquisition was highest at age 16 years. This study demonstrates the feasibility and utility of innovative methodological techniques to address novel questions related to adolescent development using existing data from multiple trials. The results suggest that mid-adolescence and the early 20s may be periods of particular risk. The findings may be useful for timing culturally and developmentally relevant prevention interventions for young African American women.

This study examined (a) differences between alcohol-only users and alcohol-marijuana co-users and (b) motives for use in relation to alcohol and marijuana use and problem use. Spring 2016 data among 1,870 past 4-month alcohol users (63.6% female, 69.1% White) from seven Georgia colleges/universities were analyzed cross-sectionally and with regard to problem use measured 4 months later. Correlates of co-use (n = 345; vs. alcohol-only use, n = 1,525) included greater alcohol and marijuana use frequency, problem drinking and marijuana use, and alcohol use motives (p's < .05). Controlling for covariates, alcohol use frequency correlated with greater marijuana use frequency and Coping and Self-enhancement alcohol use motives, but lower Conformity alcohol use motives (p's < .001); greater Coping and Self-enhancement alcohol use motives (p's < .01) predicted problem alcohol use. Marijuana use frequency correlated with greater Coping and Expansion marijuana use motives (p's < .05); greater Expansion marijuana use motives (p = .005) predicted problem marijuana use. College-based substance use interventions should target Coping and Self-enhancement alcohol use motives and Expansion marijuana use motives.
RESUMO
Epidemiology should aim to improve population health; however, no consensus exists regarding the activities and skills that should be prioritized to achieve this goal. We performed a scoping review of articles addressing the translation of epidemiologic knowledge into improved population health outcomes. We identified 5 themes in the translational epidemiology literature: foundations of epidemiologic thinking, evidence-based public health or medicine, epidemiologic education, implementation science, and community-engaged research (including literature on community-based participatory research). We then identified 5 priority areas for advancing translational epidemiology: 1) scientific engagement with public health; 2) public health communication; 3) epidemiologic education; 4) epidemiology and implementation; and 5) community involvement. Using these priority areas as a starting point, we developed a conceptual framework of translational epidemiology that emphasizes interconnectedness and feedback among epidemiology, foundational science, and public health stakeholders. We also identified 2-5 representative principles in each priority area that could serve as the basis for advancing a vision of translational epidemiology. We believe an emphasis on translational epidemiology can help the broader field to increase the efficiency of translating epidemiologic knowledge into improved health outcomes and to achieve its goal of improving population health.

BACKGROUND: This cross-sectional study used data from 483 young adult marital dyads to evaluate conflict-with-partner and support-from-partner as moderators of alcohol use on 2 outcomes: alcohol problems and marital satisfaction. A path analytic modeling approach was used to test stress-exacerbating and stress-buffering hypotheses, and to accommodate the interdependent nature of the dyadic data. METHODS: This cross-sectional sample was selected from an adolescent-to-young adult longitudinal study in which spouses were recruited into the study during a later young adult assessment when the sample was, on average, 32.5 years old. Individual interviews using computerized technology were conducted with participants. RESULTS: Findings for the outcome of alcohol problems indicated stress exacerbation in that higher conflict by each partner in interaction with higher alcohol use was associated with more alcohol problems for wives. Husbands' and wives' alcohol problems were lower when higher partner support buffered the association between alcohol use and alcohol problems. For the outcome of marital satisfaction, higher support-from-partner buffered the association between alcohol use and marital satisfaction. Finally, the combination of alcohol use and conflict-with-partner had more adverse implications for women's alcohol problems relative to men's alcohol problems. CONCLUSIONS: These findings highlight that interactions between interpersonal dimensions of romantic relationships and alcohol use by both partners contribute to our understanding of their associations with alcohol problems and marital satisfaction within the marital relationship. Furthermore, there was some sex specificity in that some interactions were more prominently associated with alcohol problems for wives than husbands.

BACKGROUND: Repressive legal environments and widespread human rights violations act as structural impediments to efforts to engage key populations at risk of HIV infection in HIV prevention, care, and treatment efforts. The identification and scale-up of human rights programs and rights-based interventions that enable coverage of and retention in evidence-based HIV prevention and treatment approaches is crucial for halting the epidemic. METHODS: We conducted a systematic review of studies that assessed the effectiveness of human rights interventions on improving HIV-related outcomes between 1/1/2003-28/3/2015 per PRISMA guidelines. Studies of any design that sought to evaluate an intervention falling into one of the following UNAIDS' key human rights program areas were included: HIV-related legal services; monitoring and reforming laws, policies, and regulations; legal literacy programs; sensitization of lawmakers and law enforcement agents; and training for health care providers on human rights and medical ethics related to HIV. RESULTS: Of 31,861 peer-reviewed articles and reports identified, 23 were included in our review representing 15 different populations across 11 countries. Most studies (83%) reported a positive influence of human rights interventions on HIV-related outcomes. The majority incorporated two or more principles of the human rights-based approach, typically non-discrimination and accountability, and sought to influence two or more elements of the right to health, namely availability and acceptability. Outcome measures varied considerably, making comparisons between studies difficult. CONCLUSION: Our review revealed encouraging evidence of human rights interventions enabling a comprehensive HIV response, yet critical gaps remain. The development of a research framework with standardized indicators is needed to advance the field. Promising interventions should be implemented on a larger scale and rigorously evaluated. Funding for methodologically sound evaluations of human rights interventions should match the demand for human rights-based and structural approaches to protect those most vulnerable from HIV infection.

The stressors associated with poverty increase the risks for externalizing psychopathology; however, specific patterns of neurobiology and higher self-regulation may buffer against these effects. This study leveraged a randomized control trial, aimed at increasing self-regulation at ~11 years of age. As adults, these same individuals completed functional MRI scanning (Mage = 24.88 years; intervention n = 44; control n = 49). Functional connectivity between the hippocampus and ventromedial prefrontal cortex was examined in relation to the intervention, gains in self-regulation, and present-day externalizing symptoms. Increased connectivity between these brain areas was noted in the intervention group compared to controls. Furthermore, individual gains in self-regulation, instilled by the intervention, statistically explained this brain difference. These results begin to connect neurobiological and psychosocial markers of risk and resiliency.

BACKGROUND: Intersectionality theory focuses on how one's human experiences are constituted by mutually reinforcing interactions between different aspects of one's identities, such as race, class, gender, and sexual orientation. In this study, we asked: 1) Do associations between intersecting identities (race and sexual orientation) and mental health (depressive symptoms) and substance use (alcohol, tobacco, and marijuana) differ between men and women? and 2) How do single or intersecting self-reports of perceived racial and/or sexual orientation discrimination influence mental health and substance use outcomes for men and women? We compared results of assessing identities versus experiences of discrimination. METHODS: Multivariable regressions were conducted on cross-sectional data from 2315 Black and White college students. Predictors included measures of sociodemographic characteristics and experiences of discrimination. Outcomes included past 2-week depressive symptoms (PHQ-9), past 30-day alcohol use, past 30-day tobacco use, and past 30-day marijuana use. RESULTS: Intersecting identities and experience of discrimination had different associations with outcomes. Among women, self-reporting both forms of discrimination was associated with higher depressive symptoms and substance use. For example, compared to women experiencing no discrimination, women experiencing both forms of discrimination had higher depressive symptoms (B = 3.63, CI = [2.22-5.03]), alcohol use (B = 1.65, CI = [0.56-2.73]), tobacco use (OR = 3.45, CI = [1.97-6.05]), and marijuana use (OR = 3.38, CI = [1.80-6.31]). However, compared to White heterosexual women, White sexual minority women had higher risks for all outcomes (B = 3.16 and CI = [2.03-4.29] for depressive symptoms, B = 1.45 and CI = [0.58-2.32] for alcohol use, OR = 2.21 and CI = [1.32-3.70] for tobacco use, and OR = 3.01 and CI = [1.77-5.12] for marijuana use); while Black sexual minority women had higher tobacco (OR = 2.64, CI = [1.39-5.02]) and marijuana use (OR = 2.81, CI = [1.33-5.92]) only. Compared to White heterosexual men, White sexual minority men had higher depressive symptoms (B = 1.90, CI = [0.52-3.28]) and marijuana use (OR = 2.37, CI = [1.24-4.49]). CONCLUSIONS: Our results highlight the deleterious impacts of racial discrimination and sexual orientation discrimination on health, in particular for women. Future studies should distinguish between and jointly assess intersecting social positions (e.g., identities) and processes (e.g., interpersonal experience of discrimination or forms of structural oppression).

BACKGROUND: Alcohol, cannabis, and tobacco use are prevalent in young adults and may be differentially related to psychological symptoms characterized as externalizing or internalizing. OBJECTIVES: This study examined the use of alcohol, cannabis, and various tobacco products in relation to externalizing (ADHD) versus internalizing factors (depression, anxiety), hypothesizing alcohol and cannabis use are associated with externalizing factors whereas tobacco use is related to internalizing factors. METHODS: Data from a 2-year longitudinal study of 2,397 US college students (aged 18-25) launched in 2014 were analyzed. Adult ADHD Self-Report Scale, Patient Health Questionnaire-9 item (assessing depressive symptoms), and the Zung Self-Rating Anxiety Scale scores were examined in relation to subsequent past 30-day use of alcohol, cannabis, and tobacco products (cigarettes, little cigars/cigarillos, smokeless tobacco, e-cigarettes, hookah), as well as nicotine dependence per the Hooked on Nicotine Checklist. RESULTS: Participants were 20.49 (SD = 1.93) years old, 64.7% female, and 65.5% White. In multivariable analyses, greater ADHD symptoms predicted alcohol and cannabis use (p = .042 and p = .019, respectively). Cigarette and little cigar/cigarillo use were predicted by greater depressive (p = .001 and p = .002, respectively), and anxiety symptoms (p = .020 and p = .027, respectively). Nicotine dependence was correlated with greater anxiety symptoms (p = .026). Counter to hypotheses, smokeless tobacco use was predicted by greater ADHD symptoms (p = .050); neither e-cigarette nor hookah use were predicted by these psychological symptoms. Conclusions/Importance: Research examining risk factors for tobacco use must distinguish among the various tobacco products. Moreover, interventions may need to differentially target use of distinct substances, including among the range of tobacco products.

It is widely accepted that adolescents exposed to violence are more likely to become perpetrators of dating aggression. However, it remains unclear whether the effects of exposure to violence on later perpetration of dating aggression vary based on the nature of the violence exposure (e.g., witnessing versus being a victim) and the contexts of exposure to violence. Thus, the relationships between two types of exposure to violence (witnessing and victimization) in early adolescence and perpetrating dating aggression in late adolescence were compared within and across three social contexts: the home, the community, and the school. Participants included 484 youth (51% females; 81% African-Americans, 18% European-Americans, 1% Hispanic or Other). Information on exposure to violence were collected at Waves 1 and 2 during early adolescence (Wave 1: M = 11.8 years old; Wave 2: M = 13.2 years old) and dating aggression data were collected during late adolescence (Wave 3: M = 18.0 years old). The results showed that across all contexts witnessing violence was a more consistent predictor of later dating aggression relative to victimization. Being exposed to violence in the home either via observation or victimization was a stronger predictor of physical dating aggression and threatening behaviors compared to being exposed to violence in the school. These findings provide a deeper understanding of the roles of various forms of exposure to violence during early adolescence in perpetrating dating aggression later in the life course.

BACKGROUND: Peer selection and socialization influences for alcohol and other substance use have been a prominent area of research especially, though not exclusively, across adolescence. This study used 4-wave prospective data from 1,004 young adults to evaluate selection and socialization influences for young adults' alcohol use and friends' alcohol use from late adolescence to later young adulthood, and incorporated the time-varying predictors of marital and parental status. In addition, sex differences in peer selection and socialization processes were tested. METHODS: Participants were recruited from high schools, and assessments were based on self-reports initially collected in adolescence (at age 17.0 years) via paper-and-pencil surveys and in young adulthood at ages 23.8, 28.9, and 33.5 years via computer-based individual interviews (computer-assisted personal interview and audio computer-assisted self-interviewing). Initial sampling included a 76% participation rate, and the retention rate was 83%. Cross-lagged panel regression models were used to evaluate hypotheses about peer selection and socialization. RESULTS: Findings indicated that friend selection processes were stronger than socialization processes across adolescence to young adulthood. Adopting marital and (especially) parental roles was negatively associated with young adults' alcohol use and percentage of friends using alcohol, and the magnitude of these relationships was stronger and more consistent for females. CONCLUSIONS: These findings indicated that across the adolescence-to-young adulthood transition, peer selection processes were more influential than peer socialization. Marital and parental roles were associated with both lower young adult alcohol use and a lower percentage of friends using alcohol, with stronger role-related effects for females relative to males.

BACKGROUND: This study used prospective data from 706 young adults to evaluate the impact of parental divorce and family history of alcoholism (FH+) on the outcomes of offspring alcohol problems, marijuana use, and interpersonal relationships with parents. METHODS: Assessments of parental divorce were based on parent reports, and young adult outcomes were collected from an offspring cohort (n = 706; X age = 33.25 years; females = 53%) via computer-based individual interviews (CAPI and ACASI). Family history of alcohol disorders for parents was based on assessments by mothers, fathers, and young adults. RESULTS: Parental divorce significantly predicted marijuana use but not alcohol problems. Maternal, but not paternal, alcoholism also significantly predicted marijuana use. Two-way interactions indicated that sex moderated several of the relationships. For example, among those with divorced parents, daughters reported higher levels of conflict with fathers than sons, and sons reported lower levels of maternal support than daughters. Paternal alcoholism was also associated with higher levels of alcohol problems among sons relative to daughters. There was also a significant 2-way interaction between divorce status and maternal alcoholism indicating that young adults who experienced both maternal alcoholism and parental divorce had the highest levels of marijuana use. CONCLUSIONS: These findings highlight the role that parental divorce and FH+ have on alcohol problems, marijuana use, and interpersonal relationships in young adulthood, and how sex may moderate some of these more nuanced relationships.

BACKGROUND: Sexual minority young adults represent a high-risk population for tobacco use. This study examined cigarette and alternative tobacco product (ATP) use prevalence across sexual orientation (heterosexual, gay/lesbian, and bisexual) among college-attending young adult men and women, respectively. METHODS: Baseline data from a two-year longitudinal study of 3386 young adult college students aged 18-25 in Georgia were analyzed. Correlates examined included sociodemographics (age, sex, sexual orientation, race/ethnicity, college type, and parental education). Outcomes included past 30-day use of tobacco (cigarette, little cigars/cigarillos [LCCs], e-cigarettes, hookah, any tobacco product used, and number of tobacco products used, respectively). Two-group, multivariate multiple regression models were used to examine predictors of tobacco use among men and women, respectively. RESULTS: Among men (N = 1207), 34.7% used any tobacco product; 18.6% cigarettes; 12.3% LCCs; 16.8% e-cigarettes; and 14.7% hookah. Controlling for sociodemographics, gay sexual orientation (OR = 1.62, p = 0.012) was associated with higher odds of cigarette use; no other significant associations were found between sexual orientation and tobacco use. Among women (N = 2179), 25.3% used any tobacco product; 10.4% cigarettes; 10.6% LCCs; 7.6% e-cigarettes; and 10.8% hookah. Being bisexual was associated with cigarette (p < 0.001), LCC (p < 0.001), and e-cigarette use (p = 0.006). Lesbian sexual orientation was associated with cigarette (p = 0.032) and LCC use (p < 0.001). Being bisexual predicted any tobacco product used (p = 0.002), as well as number of tobacco products used (p = 0.004). Group comparisons showed that the effect of sexual minority status on LCC use was significantly different for men versus women. CONCLUSION: Sexual minority women, especially bisexual women, are at higher risk for using specific tobacco products compared to heterosexual women; homosexual men are at increased risk of cigarette use compared to heterosexual men.

BACKGROUND: A limited number of measures exist to assess alcohol problems during adolescence. Item response theory modeling was used to scale a measure of adolescent alcohol problems, including drinking and driving, and then related to alcohol and other psychiatric disorders that occurred over a 15-year period. METHODS: High school students (N = 832) completed the 13-item Alcohol Problems Index (API) at age 18 years as part of a long-term longitudinal study of predictors of alcohol use and alcohol disorders. Frequency of drinking and driving was also measured during adolescence. Lifetime psychiatric disorders, including alcohol disorders, were measured during young adulthood. Rasch modeling was used to scale the severity of alcohol problems, and the scaled total score was used to prospectively predict alcohol disorders. The area under the receiver operating characteristic (ROC) curve was also computed between the adolescent alcohol problems and alcohol and other psychiatric disorders across a 15-year period. RESULTS: The prevalence of alcohol disorders was 38.7% (for alcohol dependence, it was 27.7%). Rasch modeling indicated that the API assessed a range of severity of alcohol problems and that drinking and driving were among the less severe indicators. Age 18 API scores significantly correlated with an alcohol diagnosis (0.34), and ROC curve analysis indicated that for adolescent alcohol problem scores, the diagnostic accuracy (or area under the curve) for an alcohol diagnosis by age 33 was 0.70. CONCLUSIONS: Our findings supported the unidimensionality and reliability of the API, and statistically significant prospective prediction of young adult alcohol disorders. The measurement of alcohol problems during adolescence, in addition to drinking and driving, may be beneficial in understanding adverse consequences of drinking during adolescence as well as transitions in alcohol use and alcohol disorders across the lifespan.

BACKGROUND: Alternative tobacco product (ATP) use as well as co-use of various tobacco products has increased in recent years, particularly among young adults. However, little is known about the differential role of motives for ATP or polytobacco use. METHODS: We examined (1) motives for tobacco use in relation to polytobacco versus cigarette only use and (2) motives for tobacco use in relation to levels of tobacco use across products. We analyzed data from past 30-day tobacco users at Wave 2 (Spring 2015) of a six-wave longitudinal study of 3418 students aged 18-25 years from seven U.S. colleges/universities. Variables included sociodemographics, tobacco use (cigarettes, little cigars/cigarillos [LCCs], smokeless tobacco [SLT], hookah, and e-cigarettes), and tobacco use motives (social, self-enhancement, boredom relief, and affect regulation). RESULTS: Multivariate analyses found that boredom relief motives were associated with polytobacco use versus cigarette only use (p = .007). Higher consumption levels demonstrated the following associations: cigarettes-positively with boredom relief (p = .025) and affect regulation motives (p < .001); LCCs-positively with affect regulation motives (p = .035); SLT-negatively with social (p = .003) and positively with self-enhancement (p = .017) and boredom relief motives (p = .007); and hookah-positively with social (p = .002) and boredom relief motives (p = .033) and negatively with self-enhancement (p = .004) and affect regulation motives (p = .001). CONCLUSIONS: Distinct motives for use were associated with polytobacco use among smokers. Moreover, higher levels of use among single product users also demonstrated distinct associations across use motives. These data should inform targeted cessation interventions addressing motives for use in ATP and polytobacco users. IMPLICATIONS: Interventionists, public health practitioners, and health care providers must address the increasing issue of ATP and polytobacco use and tailor interventions to reduce ATP and polytobacco use in light of the distinct motives for use.

OBJECTIVE: This study investigated associations between the use of alternative tobacco products (e.g., cigarettes, little cigars/cigarillos, hookah, e-cigarettes), alcohol, and marijuana among college students and use by their parents, siblings, and friends. A large literature exists for social influences on adolescent substance use, but few studies have focused on college samples. PARTICIPANTS: 3,418 college students from seven universities in the state of Georgia participated in this study. METHODS: Web-based surveys were completed by students (45-60 minutes) during the fall semester, 2014. RESULTS: Findings largely indicated specificity of associations between college student use and use by social influences for similar tobacco products and other substances. For each tobacco product or substance, the highest associations were for friends' use. Structural equation analyses further supported the specificity of associations and highlighted the relative strength of friends' use on student use. CONCLUSION: Similar to findings with adolescents, the use of alternative tobacco products, alcohol, and marijuana by parents, siblings, and friends is associated with higher levels of use among college students, and friends' use was the most potent correlate for this phase of the lifespan.
