Examining the Intersection of Ethnoracial Disparities and HIV Status in Substance Use Risks among U.S. Adults.

Black/African American and Hispanic Americans experience significant HIV-related disparities. Substance use might be a contributing factor to these disparities, but there is limited research on this topic. This study investigated various substance use risks by HIV status and race/ethnicity (Black, Hispanic, White) among U.S. adults. We used data from the 2005-2019 National Survey on Drug Use and Health (N = 541,921). In each racial/ethnic group, the prevalence rates of past-year and past-month tobacco, alcohol, cannabis, and cocaine use, and past-year alcohol and illicit drug use disorders were estimated by HIV status. A series of logistic regressions with the interaction term of HIV x race/ethnicity were performed to examine race/ethnicity's moderating effect on the HIV-substance use associations, while controlling for sociodemographic factors and survey year. Moderation analysis showed that HIV status's association with the risks of past-year tobacco use (AOR = 1.67, 95% CI = 1.01-2.75), past-year cocaine use (AOR = 3.80, 95% CI = 1.91-7.57), past-month cocaine use (AOR = 5.34, 95% CI = 2.10-13.60), and past-year alcohol use disorder (AOR = 2.52, 95% CI = 1.29-4.92) differed significantly between Black and White adults. Between the Hispanic and White groups, HIV status's association with the risks of past-year alcohol use (AOR = 2.00, 95% CI = 1.09-3.69), past-year cocaine use (AOR = 2.40, 95% CI = 1.06-5.39), and past-month cocaine use (AOR = 3.69, 95% CI = 1.36-10.02) also differed significantly. It is well-established that individuals with HIV face an elevated risk of substance use. Our study added valuable insights by highlighting that this phenomenon is particularly more significant among Black and Hispanic adults for several substances when compared to White adults. Implications for practice are discussed.

Opioid Misuse and Associated Health Risks among Adults on Probation and Parole: Prevalence and Correlates 2015-2020.

BACKGROUND: As state legislatures work to reduce prison populations and increase the use of community-based alternatives, limited knowledge exists about the service needs of those under criminal justice supervision in the community. Preliminary research indicates unusually high rates of disease, disability, and death. Health risks for this population include opioid misuse, a form of substance misuse that has reached epidemic proportions in the U.S. Evidence indicates this may be one of multiple epidemics this population experiences, complicating intervention. METHODS: Our study included 5154 individuals on probation or parole. Using 2015-2020 data from the National Survey of Drug Use and Health (NSDUH), we conducted a series of logistic regressions examining associations between opioid misuse and a range of health risks, controlling for sociodemographic variables and survey year. RESULTS: Approximately 17% of those on probation or parole indicated past-year opioid misuse, a rate 4 times higher than in the general population. Compared to those on probation and parole who did not misuse opioids, it was associated with higher odds of other health risk behaviors and mental health problems. For example, the odds of marijuana and cocaine use were 4-6 times higher and the odds of substance use disorder were 10 times higher. Similarly, the odds of experiencing major depressive episodes and serious psychological distress were 2-3 times higher. CONCLUSIONS: Our findings reveal a markedly high risk for opioid misuse within this population along with associated risks for behavioral and mental health problems. The complex treatment needs of this population require greater policy attention and further research.

Alcohol abstinence and binge drinking: the intersections of language and gender among Hispanic adults in a national sample, 2002-2018.

PURPOSE: Prior research examining alcohol use using national data has often overlooked vital heterogeneity among Hispanics, especially that related to language dominance and gender. We examine the prevalence of alcohol abstinence and-given prior research suggesting that many Spanish dominant Hispanics do not drink-examine rates of binge drinking among past-year alcohol users with a focus on the intersections of language and gender among Hispanics, while drawing comparisons with non-Hispanic (NH) White and NH Black adults. METHODS: Drawing from the National Survey on Drug Use and Health-a nationally representative survey between 2002 and 2018-we examine the year-by-year prevalence of alcohol abstinence and binge drinking among adults ages 18 and older in the United States. RESULTS: A disproportionate number of Spanish-dominant Hispanics abstain from alcohol use (54%), with particularly high levels of alcohol abstinence observed among Spanish dominant women (men: 39%, women: 67%). The prevalence of alcohol abstinence among English-dominant Hispanic men (24%) and women (32%) is far lower, approximating that of NH Whites (men: 23%, women: 32%). Importantly, however, among Spanish-dominant drinkers, the prevalence of binge drinking (men: 52%, women: 33%) is comparable to or greater than NH Whites (men: 42%, women: 32%). Binge drinking levels among English-dominant Hispanic men (50%) and women (37%) are greater than among their NH White counterparts. CONCLUSION: Findings paint a complex picture; consistent with prior research, we see that many Hispanics abstain from alcohol, but we also see new evidence underscoring that-among Hispanic drinkers-the prevalence of binge drinking is disconcertingly elevated.

Mutual Help Group Participation for Alcohol and Drug Problems: Uncovering Latent Subgroups.

Objective: This report aims to identify US mutual help group (MHG) participants' psycho-socio-behavioral profiles. Method: We used data from the 2015-2018 National Survey on Drug Use and Health and the sample included 1022 adults with past-year substance use disorders (SUD). We conducted a latent class analysis to identify subgroups of MHG participants and estimated multinomial logistic regression models to examine the associations between sociodemographic/intrapersonal characteristics and class membership. Results: Analyses identified three latent classes. Class 1 (Low-Risk group, 54%) reported low risks in all correlates except for serious psychological distress (SPD, 33%). Class 2 (Psychological Distress group, 30%) demonstrated high risks of major depressive episodes (86%) and SPD (93%). Class 3 (Criminal Justice System Involvement group, 16%) showed high involvement in arrests (100%) and drug-related arrests (67%) and moderate risks for SPD (54%) and behavioral problems, e.g., drug selling (46%) and theft (35%). Compared to Class 1, Class 2 was more likely to be female, out of the labor force, and to show high risk propensity, and Class 3 was more likely to have lower education and drug use disorders. Class 3 was also less likely to be older, belong to the "other" racial/ethnic category, have lower English proficiency, and report alcohol use disorder. Conclusions: The three subgroups of the US MHG participant population illustrate the complex and heterogeneous psycho-social-behavioral profiles of MHG participants with SUD. MHG referral's effectiveness may be augmented by tailoring it to the patient/client's specific psycho-socio-behavioral profile.

Who benefits from Two Way Prayer Meditation? Treatment effect moderators in a pilot randomized controlled trial of a spiritual intervention for people with substance use disorders.

Background: Two Way Prayer Meditation (TWPM) is a spiritual intervention that holds promise for improving the psychospiritual well-being of individuals in recovery from substance use disorders (SUD). This study aimed to identify moderators of TWPM's treatment effects. Moderators tested included gender, race/ethnicity, age, education, religious/spiritual affiliation, and most often used substance. Methods: This study employed a randomized controlled trial design with pretest and posttest. In total, 134 adults in four residential recovery programs participated in the study and were randomly assigned to the TWPM group or the treatment as usual control group. Linear mixed modeling was used to assess the moderating effect of each hypothesized moderator in the form of interaction tests. Sensitivity analyses were conducted by excluding cases with more than a minimum number of missing items. Results: There were no significant moderators for psychological distress, self-esteem, and most of the spiritual well-being outcomes. Both the primary and sensitivity analyses showed education significantly moderated TWPM's effect on overall spirituality self-ranking. Specifically, TWPM's positive effect on overall spirituality self-ranking was greater in the master's degree subgroup than in the less than high school subgroup. Conclusion: TWPM's treatment effects on most outcomes were not found to vary by the tested participant characteristics. The only statistically significant finding suggests clinicians may need to adjust TWPM workshop/teaching content, delivery style, or language used to reach clients with lower levels of education. Future better-powered studies are recommended to continue exploring the potential moderating effects of race/ethnicity, education, spiritual/religious affiliation, and most often used substance.

Efficacy of two-way prayer meditation in improving the psychospiritual well-being of people with substance use disorders: A pilot randomized controlled trial.

Background: The study goal was to conduct a preliminary evaluation of a spiritual intervention called Two Way Prayer Meditation's (TWPM) effectiveness on the psychological distress, self-esteem, and spiritual well-being of people with substance use disorders. Methods: This study employed a randomized controlled trial design with pretest and posttest. In total, 134 adults in four residential recovery programs participated in the study and were randomly assigned to either the TWPM group or the treatment as usual group. Primary and sensitivity analyses were conducted using linear mixed modeling. Hedges's g was used to estimate treatment effect sizes. Results: Both primary and sensitivity analyses found significant treatment effects on daily spiritual experiences (Hedges's g = 0.62), reliance on God (g = 0.49), private religious practice (g = 0.36), and positive religious/spiritual coping (g = 0.68). Treatment effects on psychological distress (g = 0.33), self-esteem (g = 0.41), and overall spirituality self-ranking (g = 0.32) reached significance in the primary analysis but not in the sensitivity analysis. Conclusions: This study found evidence of TWPM's effectiveness in improving some aspects of the spiritual well-being of adults with substance use disorders. TWPM was also found to be promising in decreasing psychological distress and increasing self-esteem.

Solution-Focused Brief Therapy for Substance Use: A Review of the Literature.

Substance use is a prevalent public health issue. Most social workers may encounter substance use in their work with clients and need effective therapeutic strategies for this issue. Since the 1980s, solution-focused brief therapy (SFBT) has been practiced with clients who have substance use problems, and clinical training materials have been developed to help practitioners learn and use SFBT in substance use treatment. Despite the longevity of the use of SFBT in practice, there are no published reviews of outcome studies to guide practitioners using SFBT. This article fills a gap in current literature on SFBT and substance use treatment by reviewing the published studies on SFBT where the focus was on substance use treatment. Five databases were searched to identify eligible studies. Experts and reference lists of relevant studies were also consulted. Nine studies were identified and included in the review. All studies reviewed found promising evidence on SFBT's effectiveness in improving substance use behaviors and related psychosocial problems. Five of the nine studies reviewed showed that SFBT can change substance use and comorbid mental health and psychosocial problems such as depression, trauma, and school- and work-related behavior problems. The article concludes with a discussion of the study results' implications for clinical practice and future research.

The Efficacy of Technology-Based Interventions for Alcohol and Illicit Drug Use Among Women of Childbearing Age: A Systematic Review and Meta-Analysis.

BACKGROUND: Alcohol and illicit drug use is prevalent among women of childbearing age and may lead to higher risk for substance-exposed pregnancy and related health consequences for both women and their offspring. Technology-based interventions (TBIs) are increasingly used to prevent or reduce substance use among women of childbearing age. The efficacy of these approaches, however, is unclear. This review critically reviewed existing research evidence from randomized controlled trials (RCTs) on the efficacy of TBIs in preventing and reducing alcohol and illicit drug use among childbearing-aged women. METHODS: Seven electronic databases were searched to identify eligible studies. Two reviewers independently screened studies, extracted data, and assessed risks of bias. Robust variance estimation in meta-regression was used to estimate effect sizes and conduct moderator analyses. RESULTS: Fifteen RCTs including 3,488 participants were included in the systematic review. Meta-analysis results based on 13 RCTs suggest that TBIs were efficacious relative to control conditions in preventing and reducing substance use among women of childbearing age (d = 0.19, 95% CI = 0.02, 0.35). Preliminary moderator analysis results suggest that the efficacy of TBIs might not vary by participant age, race/ethnicity, the type of technology used, or whether a virtual health assistant was used. TBIs' efficacy in terms of specific substance use types (alcohol use and illicit drug use) or control types (inactive control and active controls) was inconclusive, due to the limited number of studies in each category. CONCLUSIONS: This systematic review and meta-analysis found evidence of TBIs' efficacy in reducing alcohol and illicit drug use among women of childbearing age. Implications for future research and practice are discussed.

Cognitive behavioral therapy for primary care depression and anxiety: a secondary meta-analytic review using robust variance estimation in meta-regression.

Cognitive-behavioral therapy (CBT) is well supported for treating depressive and anxiety disorders. Trials of CBT for anxiety and depression in primary care have increased over the past decade, yet only one meta-analysis, published in 2015, examined this topic and the scope of that review is relatively narrow. This study conducted a systematic review and meta-analysis of primary care based CBT for depression and anxiety. A search of seven electronic databases, six professional websites, and reference lists from articles meeting inclusion criteria was conducted for studies published between 1900 and November 2018. Fifty-seven eligible studies (including 10,701 participants; 221 effect sizes) of randomized controlled trials were eligible and included for meta-analysis using robust variance estimation in meta-regression. Outcome indicators were depression and anxiety measures. An overall significant treatment effect, d = 0.400, 95% CI (0.235, 0.566), p < 0.001, of CBT for depression and anxiety disorders in primary care was identified. Subgroup analyses indicated significant treatment effect for: (1) depressive (d = 0.425, p < 0.001) and anxiety (d = 0.393, p < 0.01) outcomes, (2) studies conducted inside primary care (d = 0.412, p < 0.001), (3) studies using individual-based CBT (d = 0.412, p < 0.001), (4) studies without primary care physician involvement (d = 0.395, p < 0.001), and (5) studies using both tele-health (d = 0.563, p < 0.001) and in-person CBT (d = 0.363, p < 0.001). The percentage of White participants, treatment composition (CBT only versus CBT + other approaches), and treatment duration were significant moderators. Implications for clinical practice are discussed based on both moderator and subgroup analysis results.

Are There Gender, Racial, or Religious Denominational Differences in Religiosity's Effect on Alcohol Use and Binge Drinking Among Youth in the United States? A Propensity Score Weighting Approach.

BACKGROUND: Alcohol use/misuse is a prevalent health issue among youth and may lead to adverse consequences. Religiosity has been identified as a protective factor against alcohol use/misuse among youth. Identifying moderators in the religiosity-alcohol relationship has important implications for intervention development. OBJECTIVE: This study aims to examine whether gender, race, or religious denomination moderate the religiosity-alcohol relationship. METHOD: This study overcame previous studies' limitations by using longitudinal data from a nationally representative sample and robust analytical methods (N = 1969). This study used the propensity score weighting method to control for a large number of confounders. Propensity score weights were estimated using Generalized Boosted Models. RESULTS: Findings indicate that gender and religious denomination might not moderate the religiosity-alcohol relationship, whereas racial difference was present. Among White youth, religiosity was found to have a buffering effect against alcohol use (average treatment effect [ATE] = -0.57, CI.95 = -0.83, -0.32) and binge drinking (ATE = 0.54, CI.95 = 0.38, 0.71). However, among non-White youth, religiosity was not found to have an effect on alcohol use (ATE = 0.08, CI.95 = -0.31, 0.47) or binge drinking (ATE = 1.07, CI.95 = 0.68, 1.64). CONCLUSIONS: Findings suggest that preventions/interventions of youth alcohol involvement that are religiously based may not need to adapt their efforts based on youth's gender or religious denominations. More importantly, when addressing alcohol use/misuse issue among White American youth, religious and faith-based organizations, youth religious group leaders, and clergy should be included in the prevention/intervention efforts.

Gender Differences in the Relationships among Young Adults' Religiosity, Risk Perception, and Marijuana Use: A Moderated Mediation Model.

BACKGROUND: Studies show that religiosity is a protective factor against marijuana use. Given many religions' teachings to promote risk perception of substance use, risk perception possibly mediates the relationship between religiosity and marijuana use. Moreover, since males and females differ in religiosity, risk perception, and marijuana use, gender may moderate religiosity's indirect effect on marijuana use through risk perception and religiosity's direct effect on marijuana use. Despite substantial research on religiosity and adolescent marijuana use, little research has targeted the young adult population. OBJECTIVES: This study is the first to investigate the conditional nature of religiosity's influence on marijuana use through risk perception among young adults in the U.S. METHODS: Using a nationally representative sample from the 2014 National Survey on Drug Use and Health (N = 12,646), conditional process analysis was examined through significant test of the index of moderated mediation. Additionally, mediation analysis was conducted in male (n = 6042) and female (n = 6604) groups separately to further characterize the nature of the relationships. RESULTS: Religiosity's indirect effect on marijuana use through risk perception was found to be significantly different between males and females, while there were no gender differences in religiosity's direct effect on marijuana use. The indirect effect of religiosity on marijuana use via risk perception was significant among both males and females and was larger for females than males. CONCLUSION: Prevention interventions for young adults' marijuana use that incorporate religiosity should emphasize factors related to risk perception and have a gender informed perspective. Direction for future research is provided.

Spirituality/religiosity's influence on college students' adjustment to bereavement: A systematic review.

Bereavement is prevalent among college students and spirituality/religiosity may play an important role in their bereavement adjustment. This is the first systematic review to investigate the spirituality/religiosity's relationship with bereavement among college students. We searched 10 databases and screened 598 studies. Eight studies met the inclusion criteria. Findings suggested a favorable association of spirituality/religiosity with desirable bereavement adjustment outcomes (growth, spiritual wellbeing, and psychological wellbeing), but mixed association with undesirable bereavement outcomes (distress). We provided directions for future research to further investigate the complex relationship between spirituality/religiosity and bereavement and to refine the meaning-making coping model for the college student population.

The independent and joint effect of socioeconomic status and Multiracial status on the prevalence and frequency of substance use and depression among U.S. adolescents.

AIM: While the United States is becoming increasingly Multiracial, much is still unknown about the behavioral health of these growing new generations of Multiracial Americans. To narrow this research gap, this study investigated the prevalence/frequency of substance use and major depressive episodes [MDE] among non-Hispanic Multiracial [NHM] adolescents compared to their non-Hispanic White [NHW] counterparts and whether racial differences vary by socioeconomic status. METHODS: We analyzed data from the 2015-2019 National Survey on Drug Use and Health (N = 3,645 NHM and 34,776 NHW adolescents aged 12-17). Average Marginal Effects derived from logistic regression and negative binomial regression were used to examine (1) differences in six outcomes (past-month use of alcohol, cannabis, or drugs other than cannabis [DOTC], past-year MDE, and the frequency of alcohol and cannabis use among past-month users) by Multiracial status; (2) the moderation effect of family income on these associations. RESULTS: Compared to high-income NHW adolescents, high-income NHM adolescents reported significantly higher prevalence of past-month cannabis and DOTC use, and past-year MDE. No racial differences were observed at other income levels. Furthermore, moderation analyses indicated that the effect of Multiracial status on MDE was larger in the highest income group compared to the lowest income group. CONCLUSION: Our findings suggested that NHM adolescents, particularly those from high income families, exhibit increased prevalence of drug use and depression than NHW adolescents. As the US becomes more diverse, there is a need to further examine the social and structural factors driving the identified racial differences.

Missing Opportunities in the Screening of Alcohol Use and Problematic Use, and the Provision of Brief Advice and Treatment Information Among Individuals With Alcohol Use Disorder.

OBJECTIVES: The aim of this study was to identify sociodemographic and substance-related factors associated with being screened, receiving advice or treatment information from healthcare providers, among individuals who met the criteria for the past 12-month alcohol use disorder (AUD). METHODS: The 2015-2019 National Survey on Drug Use and Health data were analyzed to identify factors associated with being (1) asked about alcohol used among adults with AUD, who visited a healthcare provider within the past 12 months, and were not receiving AUD treatment (sample 1, n = 13,321); (2) asked about problematic use; (3) advised to reduce consumption; and (4) offered alcohol treatment information, among those in sample 1 who were asked about their use (n = 6,905). RESULTS: About half (52.9%) in sample 1 were asked about their alcohol use. Among them, 21.6% were asked about problematic use, 17.7% were advised to reduce alcohol consumption, and 7.6% were offered information. The odds of being asked about alcohol use among male participants were 0.72 times the odds of female participants; however once asked, male participants showed greater odds of being asked about problematic use (adjusted odds ratio [aOR] = 1.53, 95% confidence interval [CI] = 1.29-1.82), advised to reduce consumption (aOR = 1.64, 95% CI = 1.24-2.16), and offered treatment information (aOR = 1.77, 95% CI = 1.34-2.35). As compared with non-Hispanic White participants, other racial/ethnic groups were less likely to be asked about alcohol use; however, once asked, no differences were observed for other outcomes. CONCLUSIONS: Significant gaps in the screening and provision of advice or treatment information were identified, particularly for racial/ethnic and sex subgroups. Reducing barriers for effective screening could help address AUD-related disparities.

Culturally adapted motivational interviewing's effects on drinking in response to immigration and acculturation stressors among Latinx adults with heavy drinking problems.

INTRODUCTION: Culturally adapted motivational interviewing (CAMI) is a form of motivational interviewing that was adapted to address immigration- and acculturation-related stressors among Latinx adults who met criteria for hazardous drinking. This study hypothesized that (1) receiving CAMI was associated with reduced immigration/acculturation stress and related drinking and that (2) these associations differed by participants' acculturation and perceived discrimination levels. METHODS: This study employed a single group pre-post study design using data from a randomized controlled trial. Participants were Latinx adults who received CAMI (N = 149). The study assessed immigration/acculturation stress with the Measure of Immigration and Acculturation Stressors (MIAS) and measured related drinking with the Measure of Drinking Related to Immigration and Acculturation Stressors (MDRIAS). The study team conducted linear mixed modeling for repeated measures to examine outcome changes between the baseline and the 6-month and 12-month follow-ups and moderation effects. RESULTS: Compared to baseline, the study found significant decreases in the total MIAS and MDRIAS scores and subscale scores at 6- and 12-month follow-ups. Moderation analysis results showed that lower acculturation levels and higher levels of perceived discrimination were significantly associated with larger decreases at follow-up in total MIAS and MDRIAS scores and several subscale scores. CONCLUSIONS: Findings provide preliminary support for CAMI's efficacy in reducing immigration and acculturation stress and related drinking among Latinx adults with heavy drinking problems. The study observed more improvements among the less acculturated and more discriminated participants. Larger studies with more rigorous designs are needed.

Driving under the influence of cannabis and alcohol: Evidence from a national sample of young drivers.

OBJECTIVE: Driving under the influence (DUI) of psychoactive substances is an important public health and criminal justice issue, impacting the lives of millions of Americans. Although recent research provides up-to-date information regarding DUI among adults, there is a pressing need for research that focuses specifically on younger/underage drivers. We draw from a large, nationally-representative sample to provide up-to-date evidence as to the prevalence and key criminal justice, substance use, and behavioral health correlates of DUI of cannabis and alcohol among drivers ages 16 to 20 in the United States. METHODS: We used data from the 2020 and 2021 National Survey on Drug Use and Health (young drivers ages 16-20; N=12,863). All analyses-survey adjusted prevalence estimates, logistic regression-were conducted using Stata SE 17.0 and weighted to account for the study's stratified cluster sampling design. RESULTS: The prevalence of DUI-cannabis for the full sample-including those not endorsing past-year use-was 6.3%. Among youth endorsing past-year cannabis use, 24.5% reported DUI of cannabis. In the full sample and among cannabis users, DUI-cannabis risk was elevated among older and male youth. The prevalence of DUI-alcohol was 2.6% among all youth and 6.1% among youth reporting past-year alcohol consumption. CONCLUSIONS: Estimates indicate that more than one million young drivers each year are placing their lives and those of others at risk by operating motor vehicles after consuming cannabis and/or alcohol. Findings underscore the importance of prevention efforts targeting underaged cannabis and alcohol-impaired driving.

Mutual-help group participation for substance use problems in the US: Correlates and trends from 2002 to 2018.

BACKGROUND: Mutual-help groups (MHGs) are an integral component of the substance use disorder (SUD) treatment system in the U.S., and growing evidence suggests that they are effective and cost-effective for SUD-related problems. However, not much is known about the MHG participation patterns in the U.S. METHODS: Using the 2002-2018 National Survey on Drug Use and Health data, we estimated the annual participation rates and examined the psycho-social-behavioral correlates of MHG participation using logistic regression. RESULTS: There was no significant linear trend of MHG participation in the total US adult population between 2002 and 2018 (AOR = 0.999, 95% CI = 0.991-1.007). Among adults with past-year SUD, 4.8-7.4% of men and 4.4-6.7% of women participated in MHGs. MHG participants were more likely to be middle-aged (vs. young adults), lower education (less than high school, high school, some college vs. college or higher), lower income (annual household income <$20,000, $20,000-39,999 vs. $75,000 + ), be unemployed or not in the labor force (vs. employed), and were less likely to be Black/African American (vs. White American) and have lower English proficiency (speak English not well/not at all vs. very well/well),. CONCLUSION: MHG participation rates have remained relatively stable over the past two decades. MHGs were utilized more by individuals with lower socioeconomic status indicators and more criminal/legal involvement, possibly due to MHGs' free accessibility. However, research is needed to understand why young adults, Black, and individuals with lower English proficiency are somewhat less likely to attend MHGs.

Binge drinking in early adulthood: A machine learning approach.

Binge drinking among young adults (18-25) has been recognized as a public health concern. Considerable variation among drinking behaviors have been found among this group. Several statistical methods are available to identify theoretically and empirically meaningful correlates of binge drinking. The present study evaluated three methods for identifying correlates of binge drinking, comparing logistic regression to two machine learning methods-classification tress and random forests. While each model identified similar correlates of binge drinking-such as propensity for engaging in risky behaviors, marijuana dependence, cocaine dependence, identifying as non-Hispanic white, and higher education-the AUC analysis showed that the random forest analysis more accurately classified positive cases of binge drinking. Random forests modelling of psychosocial data is a feasible approach for identifying correlates of binge drinking behaviors among young adults. Clinical implications are discussed related to screening for binge drinking in behavioral health organizations.

Simultaneous alcohol and marijuana use among college students in the United States, 2006-2019.

Objective: Simultaneous alcohol and marijuana (SAM) use exposes college students to a myriad of adverse consequences. However, there is no recent nationally representative study on SAM use among college students in the United States (US). To provide an update to the literature, the present study aimed to examine the trends, prevalence, and correlates of SAM use among US college students between 2006 and 2019, using nationally representative data. Method: We used data from the 2006-2019 National Survey on Drug Use and Health (NSDUH) and the analytic sample was limited to the 55,669 full-time college student respondents (ages 18-22). Using logistic regression analysis, we assessed trends in SAM use prevalence and examined sociodemographic and psycho-social-behavioral correlates of SAM use. Results: The proportion of US college students who reported SAM use increased significantly from 8.13% (2006-2010) to 8.44% (2015-2019). However, examination by race/ethnicity revealed that the increasing trend was largely driven by Black college students, whose SAM use prevalence increased significantly from 5.50% (2006-2010) to 9.30% (2015-2019), reflecting a 69.09% increase. SAM use rates did not change significantly among other racial/ethnic groups. Conclusions: This study uncovered an upward trend and prevalence of SAM use among US college students, calling for more research and public health interventions in this area. At-risk subgroups that warrant more attention include college students who are Black, female, above the legal drinking age, have a lower than $20,000 household income, and reside in small metropolitan areas.
