Abstract
Pregaming represents a uniquely high-risk drinking event for young adults, and subfacets of impulsivity are robust predictors of alcohol use and related negative outcomes. Further, it is likely that pregame events contain social and physical stimuli that are particularly appealing for impulsive individuals, thus exacerbating risk for negative outcomes. However, no prior studies have investigated the extent to which impulsive personality traits interact with pregame events to confer alcohol-related risk. Thus, the present study examined the extent to which UPPS-P (urgency-perseverance-premeditation-sensation seeking-positive urgency) subfacets of impulsivity interact with the occurrence of pregaming to predict relations between pregaming, drinking quantity, and negative alcohol-related outcomes. College students (N = 737) completed a modified, online version of the 30-day Timeline Followback in which they reported drinking quantity, negative consequences, and whether they engaged in pregaming on a given day. Results indicated that sensation seeking and a lack of premeditation moderated relations between pregaming and drinking quantity such that those who are higher in sensation seeking and lower in their ability to plan ahead drank more on pregaming days. Sensation seeking and positive urgency moderated relations between pregaming and negative consequences such that those who are higher in positive urgency experience more consequences on pregaming days whereas those who are higher in sensation seeking experience less consequences. Future studies may benefit from more granular assessments of pregame-related risk as subfacets of impulsivity may confer momentary risk. Prevention efforts targeting the reduction of pregaming frequency, particularly among impulsive individuals, may lower overall risk for heavy drinking.

Abstract
Several decades of research have experimentally investigated the influence of alcohol on gambling. However, there has been only minimal experimental exploration of how gambling influences alcohol use. The aim of the current project was to evaluate how gambling influenced mood state and alcohol cravings through randomized experimental design when analyzed with comparison conditions.College students (N = 76) who reported regular alcohol use, gambling within the past year, and being college basketball fans were randomly assigned to watch a video of an exciting basketball game, watch a nondysphoric basketball game, watch a movie, or engage in slot machine gambling. Participants who watched exciting sports or engaged in gambling to reported more energized mood states and higher urges to drink compared to those who watched nondysphoric sports or a movie. These results suggest that the context of gambling may prime individuals to want to consume alcohol.

Exposure to media with alcohol-related content across young adulthood: Associations with risky drinking and consequences among high-risk 2- and 4-year college students.

[PMID: 36992619 DOI: 10.1111/dar.13654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 03/17/2023] [Accepted: 03/19/2023] [Indexed: 03/31/2023]
Abstract
INTRODUCTION Exposure to media with alcohol-related content is a known risk for alcohol use and related harms among young people. The present study used longitudinal self-report data on exposure to media with alcohol-related content to examine age trajectories across young adulthood and to estimate associations with heavy episodic drinking (HED) and negative consequences. METHOD Participants were 201 high-risk young adults enrolled in 2- and 4-year colleges (ages 18-25 at screening; 63.7% female). Repeated assessments occurred at four timepoints across a 12-month period. RESULTS Self-reported exposure to both positively and negatively portrayed alcohol-related media content decreased with age. Between-persons, controlling for alcohol use frequency, exposure to positive alcohol-related media content was positively associated with HED, and exposure to negative alcohol-related media content was inversely associated with HED; no within-person effects on HED were significant. For negative consequences, controlling for alcohol quantity, exposure to positive media content was associated with more negative consequences both between- and within-persons. Unexpectedly, exposure to negatively portrayed media content was positively associated with negative consequences at the within-person level. DISCUSSION AND CONCLUSIONS Trajectories in exposure to media with alcohol-related content showed that relatively younger participants reported greater exposure, highlighting the need for policy and prevention efforts to protect this vulnerable demographic. Findings generally indicated that positive portrayals of alcohol use increase alcohol-related risks. Moreover, increased exposure to negative portrayals in a given assessment was associated with more negative consequences-potentially by normalising or glorifying high-risk drinking and consequences, though mechanistic/causal research is needed.

Abstract
PURPOSE To determine the sociodemographic correlates of alcohol expectancies (i.e., beliefs regarding positive or negative effects of alcohol) in a national (U.S.) cohort of early adolescents 10-14 years old. A second aim was to determine associations between alcohol sipping and alcohol expectancies. METHODS We analyzed cross-sectional data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 11,868; Year 2). Linear regression analyses were conducted to estimate associations between sociodemographic factors (sex, race/ethnicity, sexual orientation, household income, parental education, parent marital status, religiosity) and positive (e.g., stress reduction) and negative (e.g., loss of motor coordination) alcohol expectancies. Additional linear regression analyses determined associations between alcohol sipping and alcohol expectancies, adjusting for sociodemographic factors. RESULTS Overall, 48.8% of the participants were female and 47.6% racial/ethnic minorities, with a mean age of 12.02 (SD 0.67) years. Older age among the early adolescent sample, male sex, and sexual minority identification were associated with more positive and negative alcohol expectancies. Black and Latino/Hispanic adolescents reported less positive and negative alcohol expectancies compared to White non-Latino/Hispanic adolescents. Having parents with a college education or greater and a household income of $200,000 and greater were associated with higher positive and negative alcohol expectancies. Alcohol sipping was associated with higher positive alcohol expectancies. CONCLUSIONS Older age, White non-Latino/Hispanic race, male sex, sexual minority status, higher parental education, and higher household income were associated with higher positive and negative alcohol expectancies. Future research should examine the mechanisms linking these specific sociodemographic factors to alcohol expectancies to inform future prevention and intervention efforts.

Abstract
Expectancy theory supports alcohol expectancies, or the expected effects of drinking, as an important factor in alcohol use behaviors. Recent research supports that alcohol expectancies fluctuate daily, but scant research has examined specific types of expectancies and their associations with alcohol use at the daily level. Consequently, the present study examined (1) the daily association between select expectancies (i.e., sociability, tension reduction, liquid courage) and likelihood of drinking, and (2) whether daily expectancies predict alcohol use outcomes (i.e., alcohol-related problems, heavy drinking) on drinking days. Participants (N = 221; 79.2% women) were primarily White (48.4%) and Black (29.7%) university students. Participants completed daily measures of expectancies, alcohol use, and alcohol-related problems each day for 14 days. Results from multilevel models revealed daily sociability as the only expectancy subscale linked with increased odds of drinking. Daily expectancies did not predict heavy drinking or alcohol-related problems on drinking days. At the between-person level, average levels of sociability and tension reduction expectancies were associated with a greater likelihood of engaging in heavy drinking and experiencing a problem. Findings highlight that fluctuations in sociability expectancies may be proximally linked to likelihood of alcohol use, which may inform just-in-time intervention efforts targeting alcohol expectancies.

Pharmacol Biochem Behav 2023; 229:173591.

Abstract
Early life stress, specifically childhood maltreatment, and parental risk for mood and substance use disorders (SUDs) are associated with increased risk for alcohol use disorder (AUD). There is limited data on how these factors interact to contribute to alcohol-related outcomes. Prior work has suggested early life stress may increase sensitivity to psychostimulants and that subjective response to alcohol is heritable. It is unclear if early life stress alters sensitivity to alcohol and interacts with parental risk for mood/SUDs, which in turn may act as a risk factor for AUD. The current study uses within-subjects placebo-controlled alcohol administration methods to investigate the effects of childhood maltreatment on subjective response to alcohol in young adults with and without parental risk of mood/SUDs. Additionally, we explored interactions with drinking context (i.e., drinking in a bar vs. non-bar context). Within individuals with parental risk for mood/SUDs, there was a positive relation between total Childhood Trauma Questionnaire (CTQ) score and how drunk individuals reported feeling across both alcohol and placebo conditions (parental risk group-by-CTQ interaction p = .01; main effect of CTQ within individuals with parental risk for mood/SUDs p = .005). When exploring interactions with drinking context (bar vs. non-bar context), we observed a significant drinking context-by-parental risk-by-CTQ interaction (p = .03), with CTQ score positively associated with greater positive valence/positive arousal feelings in the parental risk group if they consumed their beverages in the bar context (p = .004) but not if they consumed their beverages in the non-bar context. Results suggest childhood maltreatment may contribute to variation in subjective response to the positive effects of alcohol-possibly mediated by alcohol cues and/or expectancies-in young adults with parental risk for mood/SUDs.

Waddell JT, Chassin L. Multilevel longitudinal relations among impulsive traits, positive expectancies, and binge drinking from late adolescence to adulthood: A developmental test of acquired preparedness. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:996-1009. [PMID: 36977505 PMCID: PMC10289131 DOI: 10.1111/acer.15064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 03/20/2023] [Accepted: 03/21/2023] [Indexed: 03/30/2023]
Abstract
BACKGROUND The Acquired Preparedness Model (APM) posits that highly impulsive individuals develop stronger positive alcohol expectancies, which in turn predicts heavier drinking. However, most acquired preparedness studies have focused solely on between-person relations, despite the theory suggesting that there are potential developmental-specific within-person relations. Thus, the current study tested the APM from late adolescence into adulthood, while disaggregating within- from between-person relations. METHODS Data come from a multigenerational study of familial alcohol use disorder (N=653) spanning three waves 5 years apart. Participants reported their lack of conscientiousness, sensation seeking, positive alcohol expectancies, and binge drinking at each wave. First, missing data techniques were used to create a "ghost timepoint," allowing the specification of four developmental-specific timepoints representing late adolescence (age 18 to 20), emerging adulthood (age 21 to 25), young adulthood (age 26 to 29), and adulthood (age 30 to 39). Second, a Random-Intercept Cross-Lagged Panel Model tested between-person and within-person relations among variables. RESULTS At the between-person level, lower conscientiousness and sensation seeking were correlated with higher positive expectancies, and positive expectancies were correlated with more binge drinking. There were no within-person prospective relations among conscientiousness, sensation seeking, and positive expectancies. However, within-person increases in lack of conscientiousness during late adolescence predicted within-person increases in emerging adult binge drinking, and within-person increases in late adolescent and emerging adult binge drinking predicted within-person increases in lack of conscientiousness during emerging and young adulthood, respectively. Similarly, within-person increases in late adolescent and young adult sensation seeking predicted within-person increases in binge drinking during emerging adulthood and adulthood, respectively. Binge drinking did not reciprocally predict sensation seeking. CONCLUSIONS Findings suggest that acquired preparedness effects may be between persons rather than within persons. However, several within-person developmental-specific relations among conscientiousness, sensation seeking, and binge drinking were observed, outside of expectancies. Findings are discussed in terms of theory and prevention.

Abstract
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.

Abstract
AIMS This study used event-level data to identify the threshold (i.e. number of standard alcoholic drinks) at which specific negative and positive alcohol-related consequences are likely to occur. METHODS Ninety-six college students aged 18-20 reporting weekly heavy episodic drinking (HED) or at least one negative alcohol-related consequence in the past 2 weeks completed ecological momentary assessment over 28 days. Participants reported number of standard drinks consumed and negative (e.g. nausea) and positive (e.g. new friend) alcohol-related consequences on 492 drinking nights. The area under the receiver operating characteristic (AUROC) curve measured the ability of an increasing number of drinks consumed to discriminate between nights with versus without a given consequence. The Youden Index method was used to identify the optimal threshold of drinks for each consequence. Thresholds were examined for each consequence by participants' biological sex and heavy drinking status. RESULTS Across subgroups, most consequences occurred on nights where participants reported higher consumption levels relative to nights where consequences did not occur. Thresholds for negative consequences ranged between four and nine drinks and thresholds for positive consequences were between three and six drinks. CONCLUSIONS Many negative consequences are likely to occur following the traditional HED threshold of 4+/5+ drinks (females/males), with more severe consequences occurring at slightly higher thresholds. Positive consequences are likely to occur at lower thresholds. There may be an optimal number of drinks that maximize positive while minimizing negative consequences for heavy drinking college students.

Predictors of consistent condom use among young psychoactive substance users in Kampala's informal settlements, Uganda. DIALOGUES IN HEALTH 2022; 1:100080.

Abstract
Introduction The use of psychoactive substances increases the likelihood of unprotected sexual intercourse with individuals whose health status is not known, and consequently sexually transmitted infections, especially among young people. Despite this risk, there is limited evidence of the predictors of consistent condom use among young psychoactive substance users (YPSUs) in informal settings. This study examined the predictors of condom use among YPSUs in Kampala's informal settlements, Uganda. Methods A cross-sectional study was conducted among 768 YPSUs. Respondent-driven sampling was used to recruit respondents. A structured questionnaire was used to collect respondent data on condom use. Data were analysed using Stata version 15.0. Prevalence ratios (PR) were used to determine the predictors of consistent condom use. Results Out of the 744 YPSUs, only 37.4% of the respondents reported consistent condom use in the last 30 days. The prevalence of condom use was statistically lower among young people aged 20-24 years (35.4%) compared to those aged 18-19 years (43.7%), and among the married (17.3%) compared to respondents with a "single" marital status (43.0%). Being married (PR 0.42, 95% CI: 0.30-0.59), longer duration between meeting the most recent partner and having initial sexual contact with them (7 months to 1 year: PR 0.56, 95% CI: 0.36-0.88; more than a year: PR 0.36, 95% CI: 0.17-0.75) was negatively associated with consistent condom use. Spending less than 24 h between meeting the most recent partner and having initial sexual contact was positively associated with consistent condom use (PR 1.60, 95% CI: 1.24-2.08). Conclusion The prevalence of consistent condom use in the last 30 days among YPSUs was low. Marital status and the duration between meeting the most recent partner and initial sexual contact predicted consistent condom use. There is a need to intensify awareness on the importance of consistent condom use among young people.

Abstract
Self-medication of pain with alcohol is prevalent, and expectancies for alcohol analgesia likely influence pain relief and alcohol consumption. Hazardous alcohol use has been associated with greater delay discounting rates; however, little is known about the relationship between delay discounting and expectancies for alcohol analgesia. Therefore, the present study examined sex differences in associations between delay discounting and expectancies for alcohol analgesia. Healthy drinkers without chronic pain (N = 53) completed measures of expectancies for alcohol analgesia, alcohol use, and alcohol outcome expectancies. A five-trial adjusting-delay discounting task (DDT) for monetary outcomes was also administered. Regression analyses revealed that sex moderated the relationship between delay discounting and expectancies for alcohol analgesia. Steeper delay discounting rates were associated with weaker expectancies for alcohol analgesia among men when adjusting for average alcohol consumption. Among women, nonsignificant associations between delay discounting rates and expectancies for alcohol analgesia were observed. These findings provide initial evidence of sex differences in associations between delay discounting and expectancies for alcohol analgesia. The directionality of these associations was unexpected and may have implications for patterns of self-medication with alcohol. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Youths' Perceptions Of The Relation Between Alcohol Consumption And Risky Sexual Behaviour in the Western Cape, South Africa: A Qualitative Study. CHILD INDICATORS RESEARCH 2022; 15:1269-1293.

Abstract
The purpose of this study is to explore the factors that youth identify as contributing to alcohol consumption, and more specifically its relation to risky sexual behaviour among youth. We employed an exploratory qualitative method using focus group discussions with 34 young people between the ages of 18-25-years-old in low socio-economic status communities in the Western Cape province of South Africa. Data were analyzed thematically utilizing Braun and Clarke's (2006) six-step thematic analysis process. We identified two thematic domains pertaining to alcohol consumption and risky sexual behaviour, namely individual and social factors, each comprising three themes. The individual factors thematic domain comprises intrapersonal influences, employment and educational attainment; while the social factors thematic domain includes interpersonal influences, social influences, and hope for the future. Youth living in low socio-economic status communities were thought to be at greater risk of alcohol misuse and subsequent risky behaviour, given the political and social history of marginalisation, systematic oppression, and social inequality. To address alcohol use and risky sexual behavior among youth, we recommend interventions with adolescents, parents or guardians, and the community. More specifically, interventions aimed at adolescents should focus on the transition to young adulthood. Interventions with parents should focus on their role in modelling and potentially regulating alcohol consumption. Finally, community interventions should centre on drinking behaviors, levels of drinking, what constitutes harmful drinking, and how to identify when treatment and recovery support is likely to be required.

Comprehensive measurement invariance of alcohol outcome expectancies among adolescents using regularized moderated nonlinear factor analysis. Addict Behav 2022; 124:107088.

Abstract
Alcohol outcomes expectancies (AOEs) are robust predictors of alcohol initiation and escalation of drinking behavior among adolescents. Although measurement invariance is a prerequisite for inferring valid comparisons of AOEs across groups (e.g., age), empirical evidence is lacking. In a secondary data analysis study, we employed regularized moderated nonlinear factor analysis (MNLFA) to simultaneously test differential item functioning (DIF) across age, sex, race, ethnicity, socioeconomic status (SES), and alcohol initiation for a 22-item, two-factor measure of positive and negative AOEs among adolescents (analytic n = 936 drawn from a parent study of 1023 adolescents). Evidence of DIF was minimal, with no DIF for the negative AOE factor and DIF for only two items of the positive AOE factor. The item "feel grown up" exhibited DIF by age, and the item "feel romantic" exhibited DIF by SES. After accounting for DIF, the positive AOE latent factor mean differed by SES, age, and alcohol initiation, and exhibited lower variability by alcohol initiation. The negative AOE latent factor mean differed by sex and SES, with greater variability by SES and age and lower variability by alcohol initiation. Group-differences findings for age and alcohol initiation are consistent with prior work, and differences by sex and SES are a new contribution to the literature that should prompt additional research to ensure replicability. The present study demonstrates the utility of the MNLFA technique for examining comprehensive measurement invariance, particularly for applied researchers who seek to examine substantive research questions while accounting for any DIF present in the scales used.

Abstract
Objective: The current study expands the literature on simultaneous alcohol and marijuana (SAM) use by focusing on the distinction between unplanned and planned SAM use to identify potential intervention targets. This study explored whether unplanned or planned SAM use was associated with differences in alcohol and/or marijuana use and consequences. Method: A community sample of young adults (aged 18-25) with recent alcohol and SAM use was recruited [N = 409; mean (SD) = 21.61 (2.17) years; 50.9% female; 48.2% non-Hispanic/Latinx White]. Participants completed five 2-week bursts of online daily surveys (2 ×/day; 81.99% of morning and 82.23% of afternoon surveys completed) and reported on substance use intentions and behavior. Results: Descriptive findings showed that among days on which participants reported SAM use, 41.85% of the days were unplanned SAM use days. Based on daily-level results from multilevel models, on days with unplanned SAM use, young adults reported consuming fewer drinks, fewer hours high from marijuana, and lower subjective intoxication/high, compared to planned SAM use days, thus indicating that planned SAM use was riskier. Unplanned SAM use was not significantly associated with positive or negative consequences related to alcohol or marijuana, after accounting for the number of drinks or hours high from marijuana. Conclusions: Current findings suggest that interventions should target days on which young adults are planning to engage in SAM use. Future work is needed to identify factors that predict planned SAM use on specific occasions and also to disentangle the potential role of unplanned heavy use.

Alcohol Clin Exp Res 2021; 45:1888-1900.

Abstract
BACKGROUND Alcohol expectancies (AE; beliefs about the likelihood of outcomes) and valuations (beliefs about the desirability of outcomes) may help explain alcohol use by young adults. However, it remains unclear how variability in AE and valuations over time are related to alcohol-related outcomes, and whether these associations are moderated by sex. The current study addressed these gaps in knowledge by examining within-person variability among positive and negative AEs, valuations, and alcohol-related outcomes over a 12-month period. METHODS Data were collected from 433 college students (Mage = 20.06; 59.81% women) who completed surveys at 4 timepoints: at baseline and 3-month, 6-month, and 12-month follow-up. RESULTS We found substantial within-person variability in both AE and valuations (intraclass correlation coefficients ranged from 50% to 66%), and differences in variability by sex, with women showing more variability than men. Multilevel models revealed that weekly drinking was significantly higher at timepoints in which participants held relatively greater AE for sociability, sexuality, and risk/aggression, but lower when participants expected greater effects on self-perception. Weekly drinking was also higher when participants reported more favorable valuation of risk/aggression. Participants experienced significantly more negative consequences at timepoints in which they held relatively greater AE for sexuality and self-perception. No AEs were associated with a reduced likelihood of negative consequences. Participants experienced more negative consequences at timepoints in which they reported more favorable valuation of self-perception No valuations were associated with fewer consequences. Several between- and within-person associations were moderated by sex. CONCLUSIONS These findings suggest that AE and valuations are dynamic, that young adults' beliefs about the effects of alcohol varied over time, and that both negative and positive AE and valuations may be important correlates of alcohol use and consequences. These findings have implications for interventions designed to challenge expectancies and valuations with the goal of reducing alcohol use and associated consequences.

Abstract
OBJECTIVE Several studies find between-person reciprocal relations between adolescent/college drinking and positive expectancies. However, drinking and expectancies from college into adulthood are largely unstudied, as are within-person associations. During these age periods, negative alcohol consequences may represent "teachable moments" via expectancy change. The current study tested the reciprocal effects of drinking, negative consequences, and expectancies from college age to adulthood. METHOD Using data from a longitudinal study focused on familial alcohol disorder, age bands were created to model effects from college age (18-22) to young adulthood (23-28) and adulthood (29-34). Participants (N = 420) reported on their drinking, negative consequences, and expectancies across three waves (1995-2010). RESULTS Negative consequences did not predict negative expectancies, but the random intercepts of the two were highly related. Young adult negative consequences predicted a within-person increase in adult heavy drinking. A within-person increase in college age negative expectancies indirectly predicted a within-person decrease in adult negative consequences through reduced young adult drinking, whereas within-person increases in college age positive expectancies indirectly predicted a within-person increase in adult negative consequences through heavier young adult drinking. CONCLUSIONS Findings suggest that negative consequences were related to trait-level negative expectancies, even though prospective effects were not observed. Findings also suggest that college age negative expectancies were protective against future use and consequences, and this effect was unique to college age.

Abstract
BACKGROUND Many young adults engage in simultaneous alcohol and marijuana (SAM) use so that their effects overlap. Little is known about motivations for dual substance use and associations with use and consequences. This study examined daily-level associations between cross-fading motives and levels of alcohol and marijuana use and consequences. METHODS Young adults who reported SAM use in the month prior were surveyed in two 14-day bursts. Data included 1049 SAM use days from 281 young adults (age 18-25; M age = 21.80, SD = 2.16; 50 % women). Multilevel models assessed between- and within-person effects of cross-fading motives (i.e., to enhance the effects of marijuana and/or alcohol use by using them simultaneously) on alcohol and marijuana use and consequences, after adjusting for general enhancement, social, coping, and conformity motives and the amount of alcohol and marijuana used that day. RESULTS On 76 % of SAM use days, participants endorsed cross-fading motives (i.e., to enhance the effect of alcohol or marijuana or to get drunk and high at the same time). Having stronger cross-fading motives was associated with greater alcohol use, perceived intoxication, and positive alcohol consequences at the between- and within-person levels. In addition, between-person, individuals who reported stronger cross-fading motives on average reported more negative alcohol consequences and positive marijuana consequences on average. Cross-fading motives on a given day were not associated with marijuana use or marijuana consequences that day. CONCLUSIONS Cross-fading motives were common and varied from day to day. Understanding the motivational context for dual substance use may support future interventions for cross-fading.

A Daily Study Comparing Alcohol-Related Positive and Negative Consequences for Days With Only Alcohol Use Versus Days With Simultaneous Alcohol and Marijuana Use in a Community Sample of Young Adults.

Abstract
BACKGROUND Alcohol and marijuana are psychoactive substances commonly used by young adults and are independently associated with numerous acute and long-term consequences. Many young adults engage in simultaneous alcohol and marijuana (SAM) use to cross-fade (i.e., to enhance the effects of intoxication), although the extent to which alcohol use and alcohol-related consequences increase on SAM occasions compared to alcohol-only occasions is unclear. This study examines daily data among a sample of SAM users comparing SAM days to other days when young adults only used alcohol. METHODS A sample of 409 young adults (age 18 to 25; Mage = 21.6, SD = 2.2; 50.9% women) who reported SAM use in the past month completed 2 bursts of 14 days of daily surveys (28 days in total) assessing alcohol use, alcohol-related consequences, and SAM use. RESULTS Multilevel models based on alcohol-only and SAM days (n = 3,016 days; 391 individuals) indicated young adults drank more alcohol on SAM days compared to alcohol-only days (with no marijuana use). Similarly, days with SAM use were associated with more alcohol-related positive and negative consequences. The daily association between SAM use and positive consequences was statistically significant, after accounting for the amount of alcohol consumed; in contrast, the association between SAM use and negative consequences was diminished and nonsignificant. CONCLUSIONS Among young adult SAM users, days with SAM use were associated with more alcohol use and positive consequences compared to days they only drank alcohol. Further examination of the motivational context for engaging in SAM use, as well as potential physiological interactions between alcohol and marijuana use on alcohol's effects, is warranted. Alcohol interventions might benefit from addressing increased alcohol use and alcohol-related consequences as risks associated with SAM use.
