Alcohol Use Disorder Symptoms Reported during Midlife: Results from the Monitoring the Future Study among US Adults at Modal Ages 50, 55, and 60.

BACKGROUND: The extent to which adolescent substance use is associated with alcohol use disorder (AUD) symptoms in midlife is not yet fully explored. METHODS: Longitudinal data from the national Monitoring the Future study was used. The sample included 11,830 12th graders (1976-1987) who were surveyed again at modal ages 50 (37.8%), 55 (46.3%), or 60 (15.8%) in 2008-2019. Approximately 48.7% were male; 81.5% identified as non-Hispanic White. Weighted logistic and multinomial logistic regressions were used to examine associations between past 30-day use of cigarettes, marijuana, and alcohol at age 18, sociodemographics, and a midlife AUD symptom outcome (coded as non-drinking, drinking without AUD [endorsed ≤1 criterion], or AUD symptoms [endorsed 2+ criteria]). RESULTS: Prevalence of midlife AUD symptoms was 27.1%. Higher relative risk of reporting AUD symptoms (vs. drinking without AUD) was associated with age 18 substance use (any cigarette use [vs. no use], any marijuana use [vs. no use], binge drinking [vs. both no use and drinking at less than binge levels]), being male (vs. female), being non-Hispanic White (vs. non-Hispanic Black), and having a 4-year college degree. Higher relative risk of reporting non-drinking (vs. drinking without AUD) was associated with no 30-day alcohol use at age 18, being non-Hispanic Black or non-Hispanic other (vs. non-Hispanic White), and not having a 4-year college degree. CONCLUSIONS: Findings suggest substance use at age 18 has meaningful associations with midlife AUD symptoms. Dissemination of prevention and intervention efforts in adolescence and early adulthood may be important for reducing hazardous midlife drinking.

Latent profile analysis of interpersonal problems: Attachment, basic psychological need frustration, and psychological outcomes.

The purpose of this project was to identify distinct profiles of circumplex interpersonal problems, cross-validate the profiles, and examine construct validity through associations with adult attachment, basic psychological needs frustration, and psychological outcomes. Undergraduates at two universities provided survey data. In Study 1 (N = 469), latent profile analysis identified three distinct profiles of interpersonal problems. We labeled these: Flexible-Adaptive, Exploitable-Subservient, and Hostile-Avoidant. Construct validity analyses suggested the Flexible-Adaptive profile was distinguished from the other two by lower attachment anxiety, whereas the Hostile-Avoidant profile was distinguished from the other two by higher attachment avoidance. In Study 2 (N = 423), we conducted profile similarity analyses to cross-validate Study 1 results, following the multistep procedure proposed by Morin et al. (Organizational Research Methods, 2016, 19, p. 231). Results suggested that when the data from Study 2 were constrained to fit the profile model derived from Study 1, with respect to means, variance, and latent profile membership, the model fit was equivalent. In Study 2, further evidence of construct validity suggested that the Flexible-Adaptive profile was distinguished from the other two by lower relatedness frustration and by lower competence frustration. Additionally, the Hostile-Avoidant profile was distinguished from the Exploitable-Subservient profile by higher relatedness need frustration. Validity evidence for these profiles indicated that those with the Hostile-Avoidant profile reported the most negative psychological outcomes, followed by those with the Exploitable-Subservient profile, while those with the Flexible-Adaptive profile reported the best psychological outcomes.

Alcohol and cannabis motives: Differences in daily motive endorsement on alcohol, cannabis, and alcohol/cannabis co-use days in a cannabis-using sample.

OBJECTIVE: Same day use of alcohol and cannabis is prevalent among emerging/young adults and increases the risk for negative consequences. Although motives for alcohol and cannabis use are well-documented, specific motives on co-use days are under-investigated. We examined differences in motives on single substance use (i.e., alcohol or cannabis) versus co-use days in a sample of primarily cannabis-using emerging/young adults. METHODS: Participants (N=97) aged 18-25 (Mage=22.2) were recruited from an urban Emergency Department (55.7% female, 46.4% African American, 57.7% public assistance) for a prospective daily diary study about risk behaviors. Participants received prompts for 28 daily text message assessments (up to 2716 surveys possible) of substance use and motives (social, enhancement, coping, conformity). We divided use days into three groups: alcohol use only (n=126), cannabis use only (n=805), and co-use (n=237). Using fixed effects regression modeling, we fit models to estimate within-person effects of alcohol and cannabis motives on day type (alcohol/cannabis co-use versus single use). RESULTS: In adjusted models, greater cannabis-related enhancement and social motives were associated with increased likelihood of co-use days compared to cannabis-only days. In contrast, greater alcohol-related social motives were associated with co-use days versus alcohol-only days in unadjusted, but not in adjusted models. CONCLUSIONS: Findings suggest that cannabis use motives associated with increasing positive affect may be most compelling for those engaging in alcohol/cannabis use on a given day. Intervention programs for alcohol/cannabis use should address alcohol and cannabis use motives in relation to increasing positive affect and engaging in social situations.

Evaluation of the Dualistic Model of Passion for Alcohol Consumption among Emerging Adults Engaged in Risky Drinking.

Understanding factors influencing risky drinking among emerging adults could enhance interventions to reduce adverse outcomes. As a motivational construct, the dualistic model of passion (i.e., obsessive passion: drinking is compelling and conflicts with other life activities/values; harmonious passion: drinking is an important, but not overwhelming, part of life) offers a novel explanation for persistent alcohol use. Yet, the dualistic model of passion has not yet been evaluated in this at-risk population. Therefore, we examined whether the variables proposed by the dualistic model of passion were associated with sex, binge-drinking, and alcohol-related consequences among young risky drinkers. We analyzed cross-sectional baseline data collected as part of an ongoing randomized controlled trial of emerging adults (n=327; M age=22.6, SD=1.1, range 21-24; 61% female; 76% White non-Hispanic) engaged in risky drinking (AUDIT-C score ≥ 4 females, ≥ 5 males) recruited nationally via social media advertisements. A path analysis revealed significant positive direct effects between obsessive passion and binge drinking and alcohol-related consequences, and significant negative direct effects between male sex and harmonious passion and binge drinking. There was also a positive direct effect between binge drinking and alcohol-related consequences. Male sex and obsessive passion were both indirectly related to alcohol-related consequences via binge drinking. Type of passion and male sex differentiates risky drinkers who binge drink and who experienced alcohol-related consequences. Future research should examine whether targeting obsessive passion reduces binge drinking and negative outcomes.

Psychosocial functioning among regular cannabis users with and without cannabis use disorder.

BACKGROUND: In the United States, cannabis accessibility has continued to rise as the perception of its harmfulness has decreased. Only about 30% of regular cannabis users develop cannabis use disorder (CUD), but it is unclear if individuals who use cannabis regularly without ever developing CUD experience notable psychosocial impairment across the lifespan. Therefore, psychosocial functioning was compared across regular cannabis users with or without CUD and a non-user control group during adolescence (age 17; early risk) and young adulthood (ages 18-25; peak CUD prevalence). METHOD: Weekly cannabis users with CUD (n = 311), weekly users without CUD (n = 111), and non-users (n = 996) were identified in the Minnesota Twin Family Study. Groups were compared on alcohol and illicit drug use, psychiatric problems, personality, and social functioning at age 17 and from ages 18 to 25. Self-reported cannabis use and problem use were independently verified using co-twin informant report. RESULTS: In both adolescence and young adulthood, non-CUD users reported significantly higher levels of substance use problems and externalizing behaviors than non-users, but lower levels than CUD users. High agreement between self- and co-twin informant reports confirmed the validity of self-reported cannabis use problems. CONCLUSIONS: Even in the absence of CUD, regular cannabis use was associated with psychosocial impairment in adolescence and young adulthood. However, regular users with CUD endorsed especially high psychiatric comorbidity and psychosocial impairment. The need for early prevention and intervention - regardless of CUD status - was highlighted by the presence of these patterns in adolescence.

Depressive Symptoms and Gambling Behavior: Mediating Role of Coping Motivation and Gambling Refusal Self-Efficacy.

Understanding the variables that contribute to the comorbidity of depression and gambling behaviors is important in developing effective intervention strategies for those who experience gambling-related problems. The purpose of this study was to implement core concepts from Jacob's general theory of addiction and the social cognitive theory in a multiple mediation model. Specifically, we tested two models to examine whether coping motivation and refusal self-efficacy mediated the relationship between depressive symptoms, gambling related problems, and days gambled. Data was collected from 333 undergraduate students at a large public Midwest university, participating in a larger clinical trial. Analyses indicated a direct effect between depressive symptoms and gambling related problems. Depressive symptoms were found to have a significant indirect effect through coping motivation and gambling refusal self-efficacy on gambling related problems and days gambled. These results provide further support regarding the mechanisms through which depressive symptoms may increase risk for problematic gambling behavior.

Application of Generalizability Theory to the Big Five Inventory.

The purpose of the present study was to examine the Big Five Personality Inventory score reliability (BFI: John, Donahue, & Kentle, 1991) utilizing Generalizability Theory analyses. Participants were recruited from a large public Midwestern university and provided complete data for the BFI on three measurement occasions (n = 264). Results suggested score reliability for scales with 7-10 items were adequate. However, score reliability for two item scales did not reach a .80 threshold. These findings have indicated BFI score reliability was, in general, acceptable and demonstrated the advantages of using Generalizability Theory analyses to examine score reliability.

Protective Behavioral Strategies, Social Norms, and Alcohol-Related Outcomes.

The present study examined the unique contributions of protective behavioral strategies and social norms in predicting alcohol-related outcomes. Participants were 363 students from a large public university in the Midwest who reported at least one binge-drinking episode (5+/4+ drinks for men/women in one sitting) in the past 30 days. Data were collected 1/2010-3/2011. We used SEM to test models where protective behavioral strategies (PBS) and social norms were predictors of both alcohol use and alcohol-related problems, after controlling for the effects of gender. Both PBS and descriptive norms had relationships with alcohol use. PBS also had a relationship with alcohol-related problems. Overall, the findings suggest that PBS and social norms have unique associations with distinct alcohol-related outcomes.

First semester college experiences: Associations with substance use and mental health.

Introduction: Substance use (SU) and mental health (MH) concerns often occur as students transition from high school to college and may be associated with first semester experiences. Methods: Incoming first-year college students at a U.S., predominantly white, midwestern university were recruited for an intervention study. Participants reported on substance use, mental health, and college experiences at the end of their first semester of college (n = 781; 62.9 % female, mean age = 18.06 [SD = 0.24]; 77.2 % non-Hispanic white; 84.6 % heterosexual). Data for these current analyses were cross-sectional. Results: Identifying as Black, Indigenous, or another Person of Color, as a sexual minority, or as female was associated with more challenging first semester experiences. Social experiences that represent more social engagement were associated with greater substance use. College experiences reflecting an easier transition were associated with fewer mental health concerns. Alcohol use moderated the relation between academic challenges and mental health with stronger associations found at greater levels of alcohol use. Conclusions: First semester experiences were related to student mental health and substance use, suggesting the importance of early, targeted support for students to adjust to campus life.

Initiation of high-intensity drinking and subsequent substance use in young adulthood.

High-intensity drinking (HID; 10+ drinks/occasion) is associated with acute and long-term risks, including use of other substances. Earlier HID initiation is associated with high-risk alcohol use in young adulthood. Less is known about when HID initiation occurs relative to other substances and how it is associated with subsequent substance use. This study examined survey data from 468 respondents (35.5% female, 65.5% non-Hispanic white) who reported initiating HID by age 20. Weighted descriptive statistics of year of initiation for HID, marijuana, and nicotine were obtained. Weighted linear and logistic regressions examined associations between year and order of HID initiation and age 20 substance use (i.e., nicotine vaping, cigarette use, other tobacco use, marijuana use, marijuana vaping, simultaneous alcohol and marijuana use, and other illicit drug use) and alcohol use disorder (AUD) symptoms. Over half of participants initiated HID after marijuana (54.6%) and nicotine (54.4%). Later HID initiation was associated with fewer AUD symptoms and lower odds of all outcomes except marijuana and other illicit drug use. Initiating HID before marijuana was associated with lower odds of marijuana use outcomes and other illicit drug use at age 20. Initiating HID before nicotine was associated with lower odds of all substance use outcomes at age 20. Earlier HID initiation was associated with risk for subsequent substance use, but initiating HID earlier than other substances was not. Given its association with both alcohol-related outcomes and other substance use in young adulthood, earlier HID initiation is an important target for screening and intervention.

Prevalence and correlates of daily-level reasons not to drink among young adults who use alcohol.

BACKGROUND: This study examined reasons not to drink in young adults in relation to demographics, alcohol use patterns, timing (weekend vs. weekday), and typical drinking motives. METHODS: Young adults who reported past 30-day alcohol use and at least one nondrinking day (n = 614; mean age = 21.5 years ±0.53) completed a survey of alcohol-related measures (e.g., typical drinking motives) and up to 14 daily surveys that included 12 reasons not to drink assessed on nondrinking days. Multilevel logistic regressions were estimated for each reason not to drink and related covariates. RESULTS: The most common reasons not to drink on a given day were "wasn't interested in drinking" (83.4% of nondrinking days) and "didn't want to get drunk" (81.8% of nondrinking days), with over 96% of participants endorsing each of these at least once. On days (11.6%; by 29.5% of participants) when another drug was used instead of alcohol, 81.8% used cannabis. Sex, race/ethnicity, weekend (vs. weekday), and drinking motives were differentially linked to reasons not to drink. Reporting high-intensity drinking (i.e., ≥10 drinking on a day) versus binge (5-9 drinks on a day) in the past 2 weeks was linked to "had a hangover recently" (odds ratio = 2.85) as a reason not to drink. CONCLUSIONS: Findings suggest that reasons not to drink reflect personal decisions and highlight ways to acknowledge situational barriers (e.g., saving money for food and essentials) that can be emphasized in brief interventions. Furthermore, reasons not to drink and alcohol motives may work in tandem within the motivational model to impact alcohol use behaviors.

Historical Trends in Cannabis Use Among U.S. Adults Ages 19-55, 2013-2021.

OBJECTIVE: The current study used U.S. national data to examine trends in cannabis use from 2013 to 2021, focusing on changes in cannabis prevalence during young and middle adulthood and whether trends differed by sociodemographic characteristics. METHOD: Data from 2013 to 2021 from 21,182 respondents ages 19-30 and 29,871 ages 35-55 in the national Monitoring the Future panel study (followed since they were in 12th grade in 1976-2020) were used to model historical trends in cannabis prevalence (any 12-month use, any 30-day use, and near-daily use [≥20 occasions in the past 30 days]). RESULTS: Prevalence of 12-month, 30-day, and near-daily cannabis use significantly increased from 2013 to 2021 for both young and middle adults. Trends for all three behaviors indicated either consistent linear increases or two-slope increases in which the slope estimate was larger in more recent years. Historical increases in 12-month and 30-day use were similar for young and middle adulthood; the historical increase in near-daily use among middle adults had some evidence for a possible pandemic-related deviation. Historical trends did not differ by race/ethnicity or college degree. Trends for 12-month and 30-day use differed by sex, with women increasing more than men over time, especially during middle adulthood. CONCLUSIONS: Significant increases in the prevalence of cannabis use have occurred over the past decade for young and middle adults across sociodemographic groups, with some indication that near-daily use increased among middle adults at the onset of the pandemic. Although men continue to have a higher prevalence than women, the gap has narrowed, with greater increases in cannabis use among women.

Examining a curvilinear model of readiness to change and alcohol consumption.

Research examining the relationship between readiness to change and alcohol consumption among college students is inconsistent. The purpose of the present study was to extend these findings, using two different measures of readiness to change. We hypothesized a curvilinear effect would occur such that the relationship between readiness to change and alcohol use would be relatively low for students low and high on readiness to change, whereas the relationship would be relatively high for those with moderate levels of readiness to change. Data were collected from two studies: Study 1 consisted of 263 undergraduate students and Study 2 consisted of 245 undergraduates participating in either intercollegiate or recreational athletics at three US universities. In Study 1, we examined the association between both linear and quadratic scores on a readiness to change measure and alcohol use. In Study 2, we examined the relationship between scores on a stage of change measure that included subscales indicative of different levels of readiness to change and alcohol use. The pattern of relationships supported the existence of an effect where the highest levels of alcohol use occurred among those with scores representing moderate levels of readiness to change.

The moderating role of mental health on the association between COVID-related stress, isolation, and economic hardship and using substances to cope.

Since young adulthood is a vulnerable period for adverse mental health experiences and high-risk substance use, it is critical to understand the impact of the COVID-19 pandemic on young adult mental health and substance use behaviors. Therefore, we determined whether the relationship between COVID-related stressors and using substances to cope with COVID-related social distancing and isolation was moderated by depression and anxiety among young adults. Data were from the Monitoring the Future (MTF) Vaping Supplement (total N = 1244). Logistic regressions assessed the relations between COVID-related stressors, depression, anxiety, demographic characteristics, and interactions between depression/anxiety and COVID-related stressors with vaping more, drinking more, and using marijuana to cope with COVID-related social distancing and isolation. Greater COVID-related stress due to social distancing was associated with vaping more to cope among those with more depression symptoms and drinking more to cope among those with more symptoms of anxiety. Similarly, COVID-related economic hardships were associated with using marijuana to cope among those with more symptoms of depression. However, feeling less COVID-related isolation and social distancing stress was linked to vaping and drinking more to cope, respectively, among those with more symptoms of depression. These findings suggest that the most vulnerable young adults are seeking substances to cope with the pandemic, while potentially experiencing co-occurring depression and anxiety along with COVID-related stressors. Therefore, intervention programs to support young adults who are struggling with their mental health in the aftermath of the pandemic as they transition into adulthood are critical.

Alcohol use contexts (social settings, drinking games/specials, and locations) as predictors of high-intensity drinking on a given day among U.S. young adults.

BACKGROUND: This study examined whether variability in young adult drinking social settings, drinking games/drink price specials, and locations differentiated daily high-intensity drinking (HID) likelihood; whether contexts varied by legal drinking age and college status (attending a 4-year college full-time); and whether legal drinking age and college status moderated drinking context/intensity associations. METHODS: Participants (n = 818 people, 46.3% female) were part of the Young Adult Daily Life Study in 2019 to 2022. They were originally selected because they were past 30-day drinkers from the 2018 U.S. national probability Monitoring the Future 12th grade sample and because they reported one or more days of alcohol use during 14-day data collection bursts across the following 4 years (n = 5080 drinking days). Weighted multilevel modeling was used to estimate drinking context/intensity associations. Drinking intensity was defined as moderate (females 1 to 3, males 1 to 4 drinks), binge (4 to 7, 5 to 9 drinks), or HID (8+, 10+ drinks). Models controlled for other within-person (weekend, historical time period) and between-person (sex and race/ethnicity) covariates. RESULTS: Contexts differentiating HID and binge drinking days included drinking with large groups, strangers, pregaming, drinking games, and more drinking locations. Legal drinking age was associated with lower odds of free drinks but greater odds of drinking at bars/restaurants. College status was associated with lower odds of drinking alone or free drinks, but greater odds of drinking with friends, large groups, pregaming, drinking games, discounted price drinks, and at bars/restaurants, parties, and more drinking locations. Legal drinking age and college status moderated some context-intensity associations. CONCLUSIONS: Social settings, pregaming, drinking games, and drinking at more locations were associated with increased risk of HID on a given day. Legal drinking age and college status were associated with specific drinking contexts and moderated some context/intensity associations. Incorporating the contexts associated with HID into interventions may help to reduce HID and related consequences in young adults.

Young Adult Physical, Social, and Temporal Contexts of Simultaneous Alcohol and Marijuana Use.

OBJECTIVE: Simultaneous alcohol and marijuana (SAM) use is reported to be associated with heavier alcohol and marijuana use and more negative consequences, but less is known about the social, physical, and temporal contexts of SAM use. METHOD: Young adults (N = 326, 51.2% male, 49.1% White non-Hispanic) who reported past-month SAM use completed up to 14 daily surveys across five bursts that assessed SAM use and negative consequences and social, physical, and temporal contexts. We used multilevel models to examine SAM use contexts' associations with alcohol/marijuana quantity and consequences. RESULTS: The social context of alone only (vs. with others only) was associated with consuming fewer drinks. Physical contexts that included using both at home and outside the home (vs. only at home) were associated with greater alcohol and marijuana quantity and negative consequences (but not after controlling for alcohol quantity); use outside the home only (vs. only at home) was associated with more alcohol use, more alcohol consequences (but not after controlling for alcohol quantity), and fewer marijuana consequences (even after controlling for marijuana quantity). The temporal context of first engaging in SAM use before 6 P.M. (vs. after 9 P.M.) was associated with greater alcohol and marijuana quantity and more marijuana consequences (but not after controlling for number of hours high), and first engaging in SAM use between 6 and 9 P.M. was associated with more hours high. CONCLUSIONS: SAM use contexts such as using with others, using outside the home, and using earlier in the evening are typically associated with greater alcohol/marijuana quantity and consequences.

Initiation of and Escalation to High-Intensity Drinking in Young Adults.

Importance: High-intensity drinking (HID) (≥10 drinks in a row) is associated with acute negative outcomes. Identifying factors associated with HID initiation in adolescence and how it is associated with young adulthood outcomes can inform screening and prevention. Objective: To identify when individuals initiate HID and speed of escalation from first drink and first binge to first HID; characteristics associated with initiation and escalation; and whether these characteristics are associated with weekly alcohol consumption, HID frequency, and symptoms of alcohol use disorder at age 20 years. Design, Setting, and Participants: This cohort study analyzed web-based survey data from respondents in the US who reported alcohol use in the past 30 days recruited from the 2018 12th grade Monitoring the Future study and surveyed again from February 14 through April 17, 2020, at modal age 20 years in the Young Adult Daily Life Study. Only respondents who reported HID by modal age 20 years were included in the analyses. Exposures: Retrospective alcohol use initiation and self-reported alcohol use measures. Main Outcomes and Measures: Key retrospective measures included year of initiation for alcohol, first binge (≥5 drinks), and HID (≥10 drinks). Measures at age 20 years included weekly alcohol consumption, HID frequency, and Alcohol Use Disorders Identification Test (AUDIT) scores. Covariates included biologic sex, race and ethnicity, parental college education, family history of alcohol problems, and college status. Descriptive statistics and multivariable regression models were used, and all analyses were weighted. Results: Of the 451 participants with data eligible for analysis, 62.0% were male (38.0% female). On average, alcohol, binge, and HID were initiated during high school. Mean time of escalation from first drink to first HID was 1.9 (95% CI, 1.8-2.1) years and between first binge and first HID, 0.7 (95% CI, 0.6-0.8) years. Initiating HID by grade 11 (vs later) was associated with higher average weekly alcohol consumption (adjusted incidence rate ratio [aIRR], 1.40; 95% CI, 1.10-1.79]), HID frequency (aIRR, 2.01; 95% CI, 1.25-3.22]), and AUDIT score (adjusted odds ratio, 1.17; 95% CI, 1.02-1.34]) at age 20 years. Escalation from first binge to first HID in the same year (vs ≥1 year) was associated with higher HID frequency at age 20 years (aIRR, 1.66; 95% CI, 1.06-2.61). Conclusions and Relevance: These findings suggest that understanding ages and patterns of HID initiation and escalation associated with particular risk may facilitate screening for adolescents and young adults.

Incremental Predictive Validity of the Dualistic Model of Passion for Cannabis Use Among College Undergraduate Students With and Without a Cannabis Use Disorder.

Introduction: We examined whether the Dualistic Model of Passion (DMP; i.e., obsessive passion [OP] and harmonious passion [HP]) for cannabis use was prospectively associated with cannabis use and use-related outcomes, and with academic performance, relationship attachment style, and social connectedness among college students. We also explored whether the DMP was associated with outcomes when included in a model using established constructs (e.g., coping motives, refusal self-efficacy, cannabis use disorder [CUD] symptoms) as predictors of cannabis use and outcomes. Methods: Using a longitudinal cohort design (baseline, 5-month, 10-month [timepoints chosen to better correspond to 9-month academic year]), 513 undergraduate students from two universities who reported using cannabis at least four times in the past month completed a baseline survey (308 meeting criteria for CUD). We used Generalized Estimating Equations to assess longitudinal associations between OP/HP and cannabis use and academic/social outcomes at 5-month and 10-month. Results: At baseline, participants were young adults (Mean age = 20.57, SD = 2.51), 78.8% non-Hispanic, 83.8% White, 55.0% female, and 72.3% heterosexual. Greater HP was not associated with greater past month cannabis use or cannabis-related problems. Greater OP was associated with greater past month cannabis use and more cannabis-related problems. There were no significant passion by time interactions. Greater HP was associated with more anxious attachment. OP was associated with less social connection. Conclusion: This research suggests that the DMP provides novel information about factors associated with cannabis use and use-related consequences, which can aid in our understanding of cannabis use, misuse, and CUD among college students.

Assessing the Dependability of Drinking Motives via Generalizability Theory.

This study assessed the score reliability of the Drinking Motives Questionnaire-Revised (DMQ-R) via generalizability theory. Participants (n = 367 college students) completed the DMQ-R at three time points. Across subscale scores, persons, persons × occasions, and persons × items interactions accounted for meaningful variance. Findings illustrate advantages of generalizability theory-based techniques.

Race, Ethnic, and Sex Differences in Prevalence of and Trends in Hallucinogen Consumption Among Lifetime Users in the United States Between 2015 and 2019.

Background: The current study is one of the first to examine race, ethnic, and sex differences in the prevalence of and trends in hallucinogen use among lifetime users in the United States. Methods: Data came from the 2015-2019 National Survey on Drug Use and Health and included respondent's reporting ever-using hallucinogens (n = 41,060; female = 40.4%). Descriptive and multinomial logistic regression analyses were conducted in Stata. Results: Highest prevalence of past year hallucinogen use was among Asian females (35.06%), which was two-or-more times larger than prevalence of past year use among White males/females and Native American males. More than half of White males/females, Multiracial males, and Hispanic males reported had ever-used psilocybin or LSD, whereas less than one-quarter of Black males/females reported lifetime psilocybin use, and less than a third of Black females reported lifetime LSD use. Native American males had the lowest prevalence of lifetime MDMA use (17.62-33.30%) but had the highest lifetime prevalence of peyote use (40.37-53.24%). Pacific Islander males had the highest prevalence of lifetime mescaline use (28.27%), and lifetime DMT use was highest among Pacific Islander males/females (15.68-38.58%). Black, Asian, and Multiracial people had greater odds of past-year (ORs = 1.20-2.02; ps < 0.05) and past-month (ORs = 1.39-2.06; ps < 0.05) hallucinogen use compared to White people. Females had lower odds of past-year (OR = 0.79; ps < 0.05), past-month (OR = 0.78; ps < 0.05) hallucinogen use compared to males, except for lifetime use of MDMA (OR = 1.29; ps < 0.05). Conclusions: These findings should inform public health initiatives regarding potential benefits and risks of hallucinogen use among racial/ethnic groups and women.
