RESUMO
Introduction: Increasing reinforcement received from cannabis-free activities, relative to reinforcement from cannabis-related activities, is one way to reduce harmful cannabis use. Thus, accurate measurement of cannabis reinforcement is important. Using convergent mixed methods, we developed the Adolescent Reinforcement Survey Schedule-Cannabis Use Version (ARSS-CUV). ARSS-CUV, adapted from the alcohol use version, measures cannabis reinforcement by asking individuals how frequently they engaged in, and how much they enjoyed, different activities when using and not using cannabis. Method: Young adults (N = 65; M age = 20.4 years [SD = 1.8]) completed measures of cannabis use, the ARSS-CUV, and provided feedback on included activities, via focus groups. Following Standards for Educational and Psychological Testing framework, this study examined evidence of measurement validity based on item content. Results: Quantitative findings revealed that peer interactions were the most reinforcing activities, whereas activities related to family were least reinforcing. Qualitative findings indicated some confusion with question wording. Participants also indicated the importance of environmental context when using cannabis and noted who they use cannabis with may be more important than the activity they are doing. Changes were made to survey flow and response choices after participant feedback. Conclusions: ARSS-CUV includes revisions in activities solicited and response format. The revised ARSS-CUV provides opportunities to advance measurement of an important construct (i.e., reinforcement) in the study of cannabis use. Psychometric properties of the ARSS-CUV across different populations and contexts of use (e.g., polysubstance use) should be examined.
RESUMO
OBJECTIVE: Cannabis use is increasing among college students and commonly co-occurs with anxiety symptoms in this age group. Interventions that reduce anxiety may also reduce cannabis use. Behavioral economic theory suggests that substance use reductions are most likely when there is an increase in substance-free reinforcement. This randomized pilot trial evaluated the efficacy of a brief motivational intervention (BMI) for cannabis supplemented by either a substance-free activity session (SFAS) or a relaxation training (RT) session for reducing cannabis use, problems, craving, and anxiety symptoms. METHOD: One hundred thirty-two college students (Mage = 19.9; 54% female; 67% White, 31% Black) who reported five or more past-month cannabis use days were randomized to: (a) assessment-only (AO); (b) BMI plus SFAS; or (c) BMI plus RT. Participants in the BMI conditions received two individual counselor-administered sessions plus a brief phone booster session. Outcomes were evaluated 1- and 6-months postintervention. RESULTS: Relative to assessment, both BMI + SFAS and BMI + RT were associated with significant reductions in cannabis problems and craving at 1-month follow-up, and significant reductions in anxiety at 6-month follow-up. Relative to AO, BMI + RT was associated with significant reductions in cannabis use at 1-month follow-up. There were no differences between BMI conditions. CONCLUSIONS: This pilot trial was not adequately powered to conclusively evaluate relative efficacy but provides preliminary support for the short-term efficacy of both two-session interventions for reducing anxiety and cannabis-related risk among nontreatment seeking emerging adults.

OBJECTIVE: Despite extensive literature that has identified high rates of delay discounting as a behavioral correlate of substance misuse, associations of cannabis use measures and delay discounting are less consistent. Furthermore, there is very limited research examining cannabis use using cross-commodity delay discounting tasks, where the immediate and delayed outcomes are different commodities. METHOD: Using conventional single-commodity delay discounting tasks for money and cannabis outcomes as well as cross-commodity delay discounting tasks (i.e., cannabis now vs. money later, money now vs. cannabis later), we examined associations of delay discounting rates with cannabis use frequency, cannabis use disorder symptom count, cannabis-related problems, and craving among young adult cannabis users (N = 115; M age = 20.7, SD = 2.6; M cannabis use days per month = 15.5, SD = 10.0). RESULTS: Although associations between cannabis use measures and rates of delay discounting in single-commodity conditions were modest, significant associations were observed with delay discounting rates in cross-commodity conditions. Of note, regression and model comparison analyses generally showed positive associations of cannabis measures with immediate cannabis versus delayed money delay discounting rates, and negative associations of cannabis measures with immediate money versus delayed cannabis delay discounting rates. CONCLUSIONS: The results suggest that problematic cannabis use may not be strictly associated with the inability to wait for delayed outcomes, as suggested by previous research implementing single-commodity delay discounting tasks, but also with a willingness to wait for delayed access to cannabis.

Motives for alcohol use and behavioral economic measures of demand are associated with alcohol consumption and alcohol-related problems. However, it is unclear how differences in reasons for alcohol use may affect alcohol demand. Additionally, although alcohol is commonly used to self-manage conditions such as pain and sleep problems, the impact of these reasons for alcohol use on alcohol demand is not well characterized. The present study addressed this gap. Participants were adults recruited via Amazon Mechanical Turk as part of a larger study investigating health behaviors. Analyses included participants who reported alcohol use in the past year (N = 637). Participants were categorized as having recreational, therapeutic, or both recreational and therapeutic reasons for using alcohol. A brief, three-item measure of alcohol demand was administered. Multivariate analysis of variance (MANOVA) analyses revealed that alcohol drinkers endorsing both recreational and therapeutic reasons for use had significantly higher average intensity, Omax, and breakpoint indices compared to those who only reported recreational or therapeutic drinking motives (ps < .05; Cohen's d = .09-.17). Secondary analyses revealed differences in demand according to therapeutic reason for alcohol use endorsed. Significant main effects were found for use to relieve pain and anxiety/depression/stress, while interactive effects were detected for use to relieve pain and improve sleep and use to relieve pain and anxiety/depression/stress. Overall, results suggest that alcohol demand is highest in drinkers who consume alcohol for both therapeutic and recreational reasons. This group may be at elevated risk for alcohol use disorder and alcohol-related consequences. Continued research is necessary to examine this possibility.

Hypothetical purchase tasks assess substance demand, but the length of purchase tasks makes repeated assessment of state-dependent changes in demand difficult, often limiting clinical utility. Although brief assessments of alcohol and cigarette demand exist, brief measures of cannabis demand do not. College students (N = 209, Mage = 19.92, SD = 1.45; 63% female; 56.9% non-Hispanic Caucasian) who reported using cannabis at least 3 days in the past month, completed an online survey including the full-length marijuana purchase task (MPT), a three-item brief assessment of marijuana demand (BAMD) assessing intensity, Omax and breakpoint, and cannabis use outcomes. Convergent and divergent validity were examined. Independent samples t tests compared demand on the BAMD and MPT based on presence or absence of cannabis use disorder (CUD) symptoms, and one-way between-subject analyses of variance compared effects of CUD severity (mild/moderate/severe) on BAMD indices. All indices were significantly correlated across both assessment measures (ps < .01). Similarly, all indices on both demand measures were significantly correlated with craving, CUD severity, and cannabis-related consequences (ps < .01); whereas only intensity and Omax were significantly correlated with cannabis use frequency (ps < .01). Individuals with (vs. without) CUD symptoms reported significantly greater intensity and Omax (ps < .01) and significant differences in CUD severity on BAMD indices were found as well (ps < .05). The BAMD demonstrated convergent and divergent validity with the MPT. Findings suggest that brief cannabis demand can be easily assessed as an indicator for high-risk cannabis use. Thus, the BAMD may be a useful and clinically relevant tool to assess cannabis demand in real-world settings. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Purchase tasks are used to measure the value, or demand, for various substances by assessing the amount of a substance individuals would purchase across a series of escalating prices. Marijuana purchase task (MPT) has been previously developed; however, cannabis can be consumed in various forms and measurements, thus raising questions about the applicability of the MPT across cannabis users. An adaptive MPT was developed to allow participants to select their preferred product (e.g., herbal, dabs) and division (e.g., hits, grams). Little research has been done to assess the temporal stability of these measures. Participants (N = 50, Mage = 35.3) who reported at least monthly cannabis use were recruited via Amazon's Mechanical Turk and completed a baseline and repeated original and adaptive MPT. Seventy-two percent (N = 36) of the sample reported the same preferred product and division. Results indicated that the baseline and repeated original MPT were significantly correlated across all indices (rrange = .37-.73), while the baseline and repeated adaptive MPT was significantly correlated with Pmax (r = .31, p = .029) and Omax (r = .57, p < .001). Permutation testing comparing the difference between the original and adaptive MPT on all indices demonstrated a difference for break point (rdifference = .52, p = .004) and elasticity (rdifference = .94, p = .005). Correlations were lower between participants who switched their preferences on the adaptive MPT. Only elasticity was significantly different (rdifference = .93, p = .012) between tasks among participants who did not switch their preferences. Results provide support that both the original and adaptive MPT are reliable across repeated measurement and demonstrate the importance of assessing cannabis product and division preferences.

Behavioral economics suggests that individuals are likely to engage in a behavior if it is more reinforcing and readily available than other possible options. In real-world environments, sedentary behaviors are often more reinforcing and easily available than physical activities. In order to promote regular physical activity in an environment with sedentary alternatives, it is important to understand the proportion of overall reinforcement that is derived from physical activity (i.e., relative reinforcement, RR). Conceptually similar laboratory-research supports this notion, but applications to individual, real-world environments remain understudied. The current study used a novel survey-based approach to estimate the RR of common physical activities. Healthy adults (N = 348, M age = 39.0 ± 8.7) from the United States completed an online survey between April-May 2020, including a modified activity survey with ten physically active and ten sedentary activities. Regression analysis showed that total RR of physical activity was related to greater physical activity levels when controlling for enjoyment and other covariates. Four factors were identified (household, conditioning, sports, and outdoor activities) using exploratory structural equation modeling, but internal consistency was limited when items were constrained to each factor in the structural equation model. Previous laboratory findings on overall RR of physical activity were replicated with the survey-based measure, but further improvement for relative reinforcement of different sub-domains of physical activity is needed. Researchers and practitioners can use this survey to determine attractive physical activities on the individual level that can compete with sedentary leisure activities.

Objective: The purpose of this study was to examine patterns of concurrent cannabis and other substance use and their differential associations with cannabis-related problems and academic outcomes in college students. Participants: Participants were undergraduate students (N = 263; M age = 19.1 years; 61.2% female) who were eligible if they used cannabis at least 3 days in the past month (M = 10.1 days). Method: Substance use, academic-related outcomes, and measures of Cannabis Use Disorder (CUD) severity and problems were obtained in an online survey. Results: The five groups evaluated were cannabis-only users (5.3%), cannabis and alcohol (47.1%), cannabis, alcohol and cigarettes (16.7%), cannabis, alcohol and other substances (14.8%), or all-substances (16%). Cannabis-only and all-substance users reported using cannabis most frequently (ps ≤ .034), but only the latter reported greater CUD severity, problems, and poorer academic outcomes. Discussion: College student polysubstance users may be at increased risk for poorer outcomes compared to cannabis-only users and other groups.
RESUMO
BACKGROUND: Deaf and hard-of-hearing (DHH) patients are an underserved priority population. Existing, although contextually limited, findings indicate that DHH patients are more likely to use the emergency department (ED) than non-DHH patients. However, little attention has been given to the differences in ED utilization by patients' language modalities. OBJECTIVE: We hypothesized that DHH ASL-users and DHH English speakers would have higher rates of ED utilization in the past 36 months than non-DHH English speakers. METHODS: We used a retrospective chart review design using data from a large academic medical center in the southeastern United States. In total, 277 DHH ASL-users, 1000 DHH English speakers, and 1000 non-DHH English speakers were included. We used logistic regression and zero-inflated modeling to assess relations between patient segment and ED utilization in the past 12- and 36-months. We describe primary ED visit diagnosis codes using AHRQ Clinical Classifications Software. RESULTS: DHH ASL users and DHH English speakers had higher adjusted odds ratios of using the ED in the past 36-months than non-DHH English speakers (aORs = 1.790 and 1.644, respectively). Both DHH ASL users and DHH English speakers had a higher frequency of ED visits among patients who used the ED in the past 36-months (61.0% and 70.1%, respectively). The most common principal diagnosis code was for abdominal pain, with DHH English speakers making up over half of all abdominal pain encounters. CONCLUSIONS: DHH ASL users and DHH English speakers are at higher risk of using the ED compared to non-DHH English speakers. We call for additional attention on DHH patients in health services and ED utilization research.

STUDY OBJECTIVES: Cannabis use is common among young adults and has been proposed as a potential treatment for insomnia. However, controlled studies examining the impact of cannabis use on insomnia symptoms are rare. This secondary analysis of published trial data tested cannabis use during cognitive behavioral treatment for insomnia (CBT-I) as a moderator of treatment efficacy. METHODS: Young adults (ages 18-30 years) who reported past-month binge drinking (4/5+ drinks for women/men) and met diagnostic criteria for insomnia disorder were randomized to CBT-I (n = 28) or sleep hygiene (n = 28) groups. Interaction effects were tested using multilevel models. Outcomes included insomnia severity, actigraphy-assessed sleep efficiency, diary-assessed sleep quality, drinking quantity, and alcohol-related consequences. RESULTS: Twenty-six participants (46%; 12 in the sleep hygiene group and 14 in the CBT-I group) reported using cannabis during the treatment phase of the study, on an average of 23% of treatment days (range, 3%-100%). Relative to those who did not use cannabis, participants who used cannabis during treatment reported heavier drinking and more frequent cigarette use. Approximately 1 in 4 cannabis users (27%) reported using cannabis to help with sleep; however, cannabis users and nonusers did not differ in the use of alcohol as a sleep aid. Controlling for sex, race, drinking quantity, cigarette use, symptoms of depression, and symptoms of anxiety, use of cannabis during treatment did not moderate CBT-I effects on insomnia severity (b, -.002; p = .99) or other outcomes (all p > .20). CONCLUSIONS: CBT-I is effective in reducing insomnia symptoms among young adult drinkers with insomnia, regardless of cannabis use.

ObjectiveTo examine the Acquired Preparedness Model using a behavioral impulsivity facet and positive marijuana expectancies to examine direct and indirect effects on marijuana use and related problems. Participants: 250 college students (61.7% female, 54% white) recruited from a southeastern university. Methods: Participants completed an online survey of delay reward discounting, marijuana expectancies, consideration of future consequences, and marijuana-related outcomes. Results: Delay reward discounting and consideration of future consequences related to marijuana-related problems, but not marijuana use. However, positive marijuana expectancies did not mediate the relation between impulsivity and marijuana outcomes. Conclusions: These results emphasize delay reward discounting and consideration of future consequences as important factors associated with marijuana-related problems. Interventions aimed at decreasing delay reward discounting and augmenting future orientation may be effective in college students who report light to moderate marijuana use. Future studies would benefit from longitudinal study designs using multiple impulsivity measures among light and heavy users.

Supersized alcopops are sugar-sweetened beverages with extraordinarily high alcohol content; consumption is highly prevalent among college students and is associated with a variety of negative alcohol-related consequences. However, few studies have examined risk factors for consumption of these products. The objective of this study was to examine, among a college student sample, whether the behavioral economic principle of alcohol demand was associated with self-reported lifetime consumption of Four Loko-the most popular brand of supersized alcopop among underage drinkers. Participants were 170 undergraduate students who were at least 18 years of age and reported at least 1 day of alcohol consumption within the past month. Study participants completed a self-administered questionnaire assessing demographics, Four Loko consumption and associated problems, and alcohol demand (using the Brief Assessment of Alcohol Demand). Hierarchical logistic regression analyses revealed that intensity (drinks they would consume if free) significantly predicted Four Loko consumption but not breakpoint (maximum expenditure per drink) or Omax (maximum expenditure for all drinks). Findings support that students who prefer consuming large quantities of alcohol when it is free are more likely to have consumed Four Loko. Interventions increasing price or reducing the availability of Four Loko may be especially protective for this at-risk population. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Youth involved in the juvenile justice system are at elevated risk for suicide and co-occurring mental health symptoms. This study aims to examine the suicide risk and treatment needs of court-involved, non-incarcerated (CINI) youth, and to understand the acceptability and effectiveness of implementing a mental health screening procedure at time of first court contact. By embedding a forensic mental health screening tool into the intake process of a family court diversionary program, a total of 891 youth (aged 12-18) were assessed using the Massachusetts Youth Screening Instrument-2 (MAYSI-2). Analysis of screening responses revealed 12.5% of youth indicated risk for suicide with risk levels differentiated by youth sex, race and ethnicity. Suicide ideation was also significantly associated with flagging, an indication of clinical risk, on all other scales of the MAYSI-2, as well as subsequent referrals to treatment. Screening for suicide at first point of court contact within an existing diversionary program may serve as a critical and effective point of intervention for youth in need.

Deaf and hard-of-hearing (DHH) populations are understudied in health services research and underserved in healthcare systems. Existing data indicate that adult DHH patients are more likely to use the emergency department (ED) for less emergent conditions than non-DHH patients. However, the lack of research focused on this population's ED utilization impedes the development of health promotion and quality improvement interventions to improve patient health and quality outcomes. The purpose of this study was to develop a conceptual model describing patient and non-patient (e.g., community, health system, provider) factors influencing ED utilization and ED care processes among DHH people. We conducted a critical review and used Andersen's Behavioral Model of Health Services Use and the PRECEDE-PROCEED Model to classify factors based on their theoretical and/or empirically described role. The resulting Conceptual Model of Emergency Department Utilization Among Deaf and Hard-of-Hearing Patients provides predisposing, enabling, and reinforcing factors influencing DHH patient ED care seeking and ED care processes. The model highlights the abundance of DHH patient and non-DHH patient enabling factors. This model may be used in quality improvement interventions, health services research, or in organizational planning and policymaking to improve health outcomes for DHH patients.

BACKGROUND: Justice-involved youth report high rates of substance use and related problems that are associated with treatment needs; however, data on screening and linkage to treatment within the justice system is lacking. To further inform the juvenile justice behavioral health cascade of care, this study examined factors associated with identified problematic substance use and treatment referral using two screening tools. METHOD: As part of a family court intake process, 348 justice-involved youth received two screening measures, the MAYSI-2 alcohol/drug use subscale and the CRAFFT. Both tools are designed to indicate early warning signs of substance use problems and signal referral for further clinical evaluation or treatment. Chart review analysis examined whether demographic variables (sex & race), severity of use, and type of substance used were associated with positive screens on either or both measures and subsequent treatment referral. RESULTS: Half (51.2%) of youth were identified as having problematic substance use (a positive screen) on at least one of the screeners. Overall, 38.5% positively screened on the CRAFFT with only 0.3% positively screening on just the MAYSI-2 alcohol/drug scale. Cannabis only users were less likely to positively screen on the MAYSI-2 compared to youth who reported use of both alcohol and cannabis. Positively screening on one versus both screeners was not associated with referral, yet many (28%) who positively screened were not referred for services. CONCLUSIONS: The CRAFFT may be more accurate at identifying youth specifically at risk for problematic cannabis use compared to the MAYSI-2 alcohol/drug subscale. Regardless of tool used, treatment referral was low, highlighting the need for accurate identification of treatment needs of substance-using, justice-involved youth. Interventions to facilitate referrals for youth with problematic substance use are needed.

Delay discounting (DD) refers to the decrease in the subjective value of a reward as the delay to its receipt increases. As high rates of DD are consistently associated with measures of substance misuse, DD is an important construct in current conceptualizations of addiction. High rates of DD appear to model preference for the immediate rewards provided by substance use, resulting in the interpretation that individuals with substance use disorder are generally unable or unwilling to delay gratification to obtain larger but delayed rewards. This interpretation is largely based on literature implementing binary choice tasks using differing amounts of the same commodity (i.e., single-commodity), in which high rates of DD can result from relative preference for the immediate outcome or relative dispreference for the delayed outcome. We propose that tasks using different commodities (i.e., cross-commodity) for the immediate and delayed outcomes offer potential in disentangling these dissociable and consequentially distinct interpretations. Our review suggests that cross-commodity DD tasks provide unique insights into understanding addiction not captured by single-commodity designs. We conclude that more research implementing cross-commodity DD tasks is needed to better understand the role of intertemporal choice in addiction and recovery.

The demand for opioid medication to effectively treat pain has contributed to the surging opioid crisis, which is a major source of morbidity and mortality in the U.S. More than 100,000 people begin opioid maintenance treatment (OMT) annually, the standard pharmacotherapy for opioid use disorder (OUD). Although OMT is the standard care for OUD, patients often experience or develop a heightened sensitivity to pain (hyperalgesia) as a result of the opioid medication, and also have high rates of stress, affective, and anxiety-related conditions. These conditions are interactive with other behavioral and environmental correlates of opioid and other substance use disorders including impulsive decision-making (e.g., harmful opioid use associated with increased delay discounting), and a lack of alternative (i.e., substance-free) and social reinforcement. Collectively these complex and multifaceted factors constitute significant predictors of lack of adherence to OMT (and other pharmacotherapies) and relapse. There is an urgent need, therefore, to develop novel adjunctive treatments that preserve the benefits of OMT and various pharmacotherapies, and simultaneously diminish continued pain and hyperalgesia, reduce stress and anxiety-related conditions, target relevant behavioral mechanism such as impulsive choice, and also serve to enhance the value of alternative and substance free activities. Here, we discuss evidence that an environmental manipulation - access to greenspace and nature - could serve as a potential adjunctive treatment to standard pharmacotherapies by targeting multiple biological and behavioral mechanisms that standard pharmacotherapies do not address.

Insomnia symptoms have been linked to problematic marijuana use among young adults, but the mechanism underlying this association and whether sex differences exist, remains unclear. Using cross-sectional data, this study examined negative mood as a mediator of the association between insomnia and marijuana problems among male and female college students. Undergraduate students (n = 267; 61% female) reporting marijuana use in the past month completed an online survey assessing insomnia symptoms, negative mood and marijuana problems. Controlling for relevant covariates, negative mood was examined as a mediator of the association between insomnia and marijuana problems using bootstrapped significance tests for indirect effects (n-boot = 1,000). Results indicated that higher levels of insomnia were associated with greater levels of negative mood (regardless of sex), which in turn were associated with greater marijuana-related problems. In conclusion, insomnia symptoms are associated with more negative mood among college students who use marijuana, and this effect on negative mood accounts for a large part of the association of insomnia symptoms with marijuana-related problems. Research is needed to determine if these associations are maintained prospectively.

BACKGROUND: Supersized alcopops are sugar sweetened beverages with high alcohol concentration; Four Loko is the most commonly consumed brand among underage drinkers. OBJECTIVES: The current study examined the prevalence and correlates of Four Loko consumption, as well as drinking location, beverage source, quantity consumed, and alcohol-related consequences among students who consumed the product before age 21. METHODS: Undergraduate drinkers (n = 1,019; 53.5% female) attending public universities in Florida, Montana, and Virginia completed a classroom survey. Multivariable logistic regression models examined first-time Four Loko experiences among students under age 21 at the time of the drinking episode (n = 336). RESULTS: Among drinkers, 46% had consumed Four Loko. The vast majority (93%) drank the product before age 21. During their first Four Loko drinking episode, 57% consumed at least one can and 10% drank two or more cans. Among underage drinkers, being male (AOR = 6.8), paying for the Four Loko (AOR = 3.1), and earlier age of alcohol initiation (AOR = 0.8) were associated with greater odds of drinking at least one can. Among underage drinkers who finished at least one can, 36% blacked out and 21% vomited. The odds of blacking out and vomiting were greater if the participant drank at least one can (AOR = 6.0, AOR = 4.0). Students in states that sold Four Loko with higher alcohol-by-volume were more likely to blackout (AOR = 2.0) and vomit (AOR = 2.5). CONCLUSIONS: Delaying the age of first alcohol use may have protective effects on supersized alcopop consumption. Increased enforcement of existing laws is needed to prevent underage access to Four Loko. Further, laws that reduce the alcohol content of Four Loko may reduce negative consequences associated with its consumption.

BACKGROUND: Four Loko, the leading supersized alcopop brand, is a pre-mixed alcoholic beverage containing up to 5.5 standard alcoholic drinks in a can. In 2013, the Federal Trade Commission (FTC) mandated the addition to Four Loko cans of a label indicating its alcohol content in standard drinks, presented as "alcohol per serving" and "servings per container." OBJECTIVE: The current study investigated whether college students accurately estimate the alcohol content in cans of Four Loko bearing the FTC mandated labels. METHOD: Undergraduate student drinkers (n = 833; 51.6% women) in three states (Florida, Montana, and Virginia) were provided an empty Watermelon Four Loko can and asked to determine the number of standard drinks it contained, using 12-ounce regular beer (Budweiser) equivalents. In Florida and Virginia, Watermelon Four Loko contains 4.70 standard alcoholic drinks; in Montana, it contains 3.13. RESULTS: More than 60% of Florida students and more than 70% of Virginia students underestimated Four Loko's alcohol content by one or more standard drinks, compared to 45% of Montana students. Multivariable logistic regression analysis found the following variables were associated with greater odds of underestimating Four Loko's alcohol content by one or more standard alcoholic drinks: being female (AOR = 2.2), having never seen nor heard of Four Loko (AOR = 1.9), and residing in Florida (AOR = 1.7) or Virginia (AOR = 2.8) versus Montana. CONCLUSIONS: Students were far less likely to underestimate alcohol content for 8% alcohol-by-volume (abv) cans compared to those with higher alcohol concentrations. Thus, policies restricting supersized alcopops' abv may help consumers better estimate their alcohol content.
