Abstract
BACKGROUND/PURPOSE Acute subjective alcohol effects appear to play an important role in predicting alcohol hangover. However, no studies have used a laboratory-based alcohol challenge to examine the concurrent or longitudinal effects of subjective alcohol responses on hangover frequency. As such, we investigated the direct and indirect effects of alcohol stimulation, sedation, liking and wanting, as measured in a controlled setting, on hangover frequency over five years. METHOD Participants were 294 young adult light-to-heavy social drinkers (aged 21-35 years, 42% female) enrolled in the Chicago Social Drinking Project. The study utilized a placebo-controlled, double blind, laboratory alcohol challenge and a battery of measures including the Biphasic Alcohol Effects Scale, Drug Effects Questionnaire, Hangover Symptom Scale, and alcohol use Quantity-Frequency Interview, with the latter two re-administered after five years. RESULTS Through the use of a path analysis, the present study found significant direct effects from alcohol liking to hangover frequency at initial testing. In addition, there were multiple significant indirect effects from greater alcohol liking and wanting to greater alcohol use quantity-frequency and, in turn, greater hangover frequency at initial testing and 5-year follow-up. Last, there were significant indirect effects from greater alcohol sedation to less alcohol use quantity-frequency and, in turn, less hangover frequency at initial testing and 5-year follow-up. CONCLUSION This study highlights the role of the hedonic reward and motivational salience of alcohol as potential mechanisms of alcohol-related consequences (i.e., hangover) among light-to-heavy social drinking young adults.

Abstract
Modern nosologies (e.g., ICD-11, DSM-5) for alcohol use disorder (AUD) and dependence prioritize reliability and clinical presentation over etiology, resulting in a diagnosis that is not always strongly grounded in basic theory and research. Within these nosologies, DSM-5 AUD is treated as a discrete, largely categorical, but graded, phenomenon, which results in additional challenges (e.g., significant phenotypic heterogeneity). Efforts to increase the compatibility between AUD diagnosis and modern conceptualizations of alcohol dependence, which describe it as dimensional and partially overlapping with other psychopathology (e.g., other substance use disorders) will inspire a stronger scientific framework and strengthen AUD's validity. We conducted a systematic review of 144 reviews to integrate addiction constructs and theories into a comprehensive framework with the aim of identifying fundamental mechanisms implicated in AUD. The product of this effort was the Etiologic, Theory-Based, Ontogenetic Hierarchical Framework (ETOH Framework) of AUD mechanisms, which outlines superdomains of cognitive control, reward, as well as negative valence and emotionality, each of which subsume narrower, hierarchically-organized components. We also outline opponent processes and self-awareness as key moderators of AUD mechanisms. In contrast with other frameworks, we recommend an increased conceptual role for negative valence and compulsion in AUD. The ETOH framework serves as a critical step towards conceptualizations of AUD as dimensional and heterogeneous. It has the potential to improve AUD assessment and aid in the development of evidence-based diagnostic measures that focus on key mechanisms in AUD, consequently facilitating treatment matching.

Abstract
BACKGROUND Alcohol administration paradigms have been used for early efficacy testing of novel compounds for alcohol use disorder (AUD). There has been an ongoing debate about sample characteristics and methodological features that affect the likelihood of detecting an early efficacy signal for AUD medications. We conducted a meta-regression to test whether the drinking level of the study sample and the peak breath alcohol concentration (BrAC) in the alcohol administration study predict the efficacy of AUD pharmacotherapies on the subjective responses to alcohol. METHODS We computed the effects of 21 medications on alcohol-induced stimulation, sedation, negative mood, and craving during alcohol administration in 49 studies. RESULTS Meta-regression analyses indicated a significant and positive effect of pre-study drinks per month on alcohol-induced stimulation (β = 0.142, p < 0.0001), such that as drinking increases, the benefit of medication over placebo decreases. There was an effect of drinks per month on negative mood (β = -0.164, p = 0.0248), such that at higher levels of drinks per month, the effects of medications on negative mood are stronger. For sedation, there was an effect of peak BrAC (β = 0.119, p = 0.0002), such that at low levels of peak BrAC, the effects of medication on sedation were null. For craving, there was a peak BrAC × drinks per month interaction such that at low levels of BrAC, a heavier drinking sample is required to detect the effects of medication on craving. Sensitivity analyses comparing naltrexone studies and non-naltrexone studies suggested that naltrexone was less sensitive to drinks per month across subjective response domains. CONCLUSIONS These analyses show that design features are critical in studies that test the effects of medications on the subjective responses to alcohol. By specifying the significance and directionality of these effects, as well as the specific points in BrAC or drinks per month at which medication effects are detectable, the study offers recommendations for design features of alcohol administration studies that aim to inform AUD medication development.

Abstract
RATIONALE One risk factor for alcohol and substance misuse is hypomanic experiences, or periods of mood elevation. Young people who report hypomanic states are more likely to develop bipolar disorder (BP), and BP and other mood disorders increase the risk of addiction. We recently reported that young adults with a history of mood elevation experience less subjective effects from a low dose of alcohol, which may be predictive of future alcohol use. The finding with alcohol raised the question of whether this dampened response to a drug also applies to other drugs, such as amphetamine. OBJECTIVE This study assessed responses of d-amphetamine in healthy young adults with varying experiences of mood elevation, as measured by the Mood Disorders Questionnaire (MDQ). METHODS Healthy 18-19-year-olds (N = 30) with a range of MDQ scores participated in three 4-h laboratory sessions in which they received placebo, 10 mg, or 20 mg d-amphetamine. They completed mood questionnaires and cardiovascular measures. RESULTS Individuals with higher MDQ scores reported less stimulation and euphoria after 10 mg, but not 20 mg, d-amphetamine, than individuals with lower scores. MDQ scores were not related to cardiovascular responses to the drug. CONCLUSIONS A history of mood elevation experiences or hypomania states is related to dampened response to a low dose of a psychostimulant drug, extending previous findings with dampened response to alcohol. This phenotype for mood disorders of dampened responses to drugs may contribute to risk for subsequent drug use or misuse.

Abstract
BACKGROUND Considerable evidence indicates that a low level of subjective response to alcohol's acute effects (i.e., low sensitivity) is associated with enhanced risk for alcohol use disorder (AUD). Recent work suggests that the highest risk response profile consists of blunted sensitivity to alcohol's sedation-like effects, coupled with enhanced sensitivity to alcohol's stimulation-like effects (i.e., differential sensitivity). A largely separate body of work indicates that enhanced reactivity to alcohol-related cues is associated with increased AUD risk. AIMS The current research examined the extent to which variability in alcohol response phenotypes is associated with enhanced P3 event-related potential (ERP) responses to alcohol-related pictures (ACR-P3), and whether this reactivity varies according to depicted drinking contexts. METHODS Eighty young adults (aged 18 to 33 years) completed a self-report measure of alcohol sensitivity (the Alcohol Sensitivity Questionnaire) and viewed images depicting drinking in naturalistic contexts, alcohol and nonalcohol beverages in isolation (devoid of naturalistic drinking context), and neutral nonbeverage control images while ERPs were recorded. RESULTS Results indicated that blunted sensitivity to alcohol's sedative-like effects was differentially associated with enhanced ACR-P3 but reduced P3 reactivity to nonalcohol cues. Variation in sensitivity to alcohol's stimulant-like effects was not associated with differential ACR-P3. Contrary to predictions, these effects were not potentiated by drinking contexts. CONCLUSIONS The current results replicate and extend previous work linking low alcohol sensitivity with enhanced incentive salience for alcohol-related cues and suggest that cues depicting drinking contexts are less likely to differentiate high-risk from low-risk drinkers.

Abstract
Randomized clinical trials have established the efficacy of naltrexone for reducing quantity of alcohol consumption and incidence of relapse to heavy drinking. To evaluate putative treatment mechanisms, human laboratory studies have examined naltrexone's effects on alcohol responses and self-administration during short-term medication protocols. Results from these studies are inconsistent and have yet to be examined in aggregate. This meta-analysis aimed to quantify naltrexone's effects on alcohol self-administration and craving in the context of placebo-controlled human laboratory trials. Potential moderators of medication effects were also examined. Meta-analyses of alcohol self-administration (k = 9, N = 490) and craving (k = 16, N = 748) confirmed that, under controlled experimental conditions, naltrexone reduces the quantity of consumption (Hedges' g = -.277, SE = .074, 95 percent CI = -.421, -.133, p < .001) and magnitude of self-reported craving (g = -.286, SE = .066, 95 percent CI = -.416, -.156, p < .001) relative to placebo. Subgroup and moderation analyses found no evidence that effect sizes differed by study population (dependent versus non-dependent drinkers), laboratory paradigm or duration of medication exposure. These results substantiate prior evidence for reductions in event-level craving and consumption as potential treatment mediators, also establishing effect sizes to inform future human laboratory trials. From a clinical perspective, these results may provide additional evidence regarding naltrexone's efficacy in the context of acute or subacute dosing regimens.

Abstract
PURPOSE OF REVIEW Human laboratory studies involving alcohol administration have generated critical knowledge about individual differences in risk for alcohol use disorder (AUD), but have primarily involved adult populations and cross-sectional research designs. Ethical constraints have largely precluded human laboratory alcohol research in adolescence, and prospective studies have been rare. This paper provides an overview of developmental considerations in human laboratory alcohol research, with a focus on studies conducted with youth. RECENT FINDINGS Recent human laboratory studies from Europe and Canada have examined aspects of alcohol response during late adolescence, while recent survey studies from the United States have highlighted methods for circumventing alcohol administration in studies of adolescents. SUMMARY Across several decades of research, exceedingly few laboratory studies have examined developmental differences in alcohol responses or utilized prospective designs. Efforts to prioritize prospective research would further clarify the role of alcohol sensitivity traits as predictors or markers of AUD onset and progression.

Abstract
In spite of high prevalence and disease burden, scientific consensus on the etiology and treatment of Alcohol Use Disorder (AUD) has yet to be reached. The development and utilization of experimental psychopathology paradigms in the human laboratory represents a cornerstone of AUD research. In this review, we describe and critically evaluate the major experimental psychopathology paradigms developed for AUD, with an emphasis on their implications, strengths, weaknesses, and methodological considerations. Specifically we review alcohol administration, self-administration, cue-reactivity, and stress-reactivity paradigms. We also provide an introduction to the application of experimental psychopathology methods to translational research including genetics, neuroimaging, pharmacological and behavioral treatment development, and translational science. Through refining and manipulating key phenotypes of interest, these experimental paradigms have the potential to elucidate AUD etiological factors, improve the efficiency of treatment developments, and refine treatment targets thus advancing precision medicine.

Abstract
BACKGROUND Motivational models of alcohol use suggest that individual differences in sensitivity to the acute subjective effects of alcohol play an important role in motivational pathways to alcohol use. However, few studies have examined the link between drinking motives and subjective responses to alcohol. This study investigated the associations of coping and enhancement drinking motives with subjective stimulant and sedative effects during a laboratory alcohol administration session. We also examined whether stimulation and sedation following alcohol administration mediated the relationships between drinking motives and postalcohol ratings of alcohol wanting and liking. METHODS Heavy episodic drinkers (n = 147, ages 19 to 25) at 2 sites participated in an intravenous alcohol administration session in which blood alcohol concentration was raised to a target of 80 mg% over 20 minutes. Participants completed measures of stimulation and sedation at baseline and 20 minutes and also rated alcohol liking and wanting at 20 minutes. Drinking motives and alcohol use were assessed during a previous laboratory visit. RESULTS A path analysis controlling for baseline stimulation and sedation showed that enhancement motives were positively associated with postalcohol stimulation and negatively associated with postalcohol sedation. In contrast, coping motives were positively associated with postalcohol sedation. In turn, postalcohol stimulation, but not sedation, was associated with alcohol wanting and liking. Further, indirect pathways from enhancement motives to postalcohol wanting and liking mediated through postalcohol stimulation were statistically significant. Coping motives, on the other hand, were directly associated with increased postalcohol wanting and liking. CONCLUSIONS The results demonstrate that drinking motives are linked with individual differences in sensitivity to the effects of alcohol, which may serve as a mechanism underlying alcohol reinforcement and the motivation to consume more alcohol during a drinking episode.

Abstract
BACKGROUND Varenicline has been found to decrease alcohol-motivated behaviors. Recent warnings regarding aversive events associated with varenicline used in conjunction with alcohol warrant further investigation into the safety of the drug when combined with alcohol. The purpose of this preliminary investigation was to examine the effect of combining varenicline with a high, fixed dose of alcohol on subjective reactivity and cognitive function in adults with alcohol use disorders (AUDs). METHODS This double-blind, placebo-controlled preliminary investigation examined the effects of varenicline (0, 1, 2 mg/d) on subjective reactivity, cognition, perceptual motor function, and physiologic reactivity to a fixed dose of alcohol (vs. nonalcohol control beverage) using an established laboratory paradigm in smokers and nonsmokers meeting criteria for AUDs (n = 44). All participants had completed a parent varenicline study evaluating alcohol self-administration. Each subject completed 2 fixed-dose laboratory sessions assessing reactivity to a high-dose alcohol (0.08 g/dl) or a nonalcoholic control beverage, order counterbalanced. RESULTS Varenicline attenuated alcohol-related increases in subjective intoxication and alcohol-related decreases in executive cognitive function. At baseline, varenicline reduced alcohol craving and diastolic blood pressure, and increased associative learning, working memory, and perceptual motor function. Varenicline produced nonspecific effects on diastolic blood pressure and heart rate. Overall, there were few differences in effects between 1 and 2 mg/d varenicline versus placebo. CONCLUSIONS These preliminary results continue to support the safety and use of varenicline in combination with alcohol in individuals meeting criteria for AUDs.

Abstract
Human laboratory and animal models implicate variation in the μ-opioid receptor gene (OPRM1) as relevant for alcohol-related reward. OPRM1 is associated with alcohol self-administration in non-human primate studies, but the relevance of this finding to human models is unclear. This study used computer-assisted self-infusion of ethanol (CASE) to examine associations among OPRM1 A118G genotype, subjective responses to alcohol and intravenous alcohol self-administration in young heavy drinkers (n = 40, mean age = 19.95 years, SD = 0.82). Participants completed a 2-hour CASE session comprising a priming phase followed by ad libitum self-administration in a free-access paradigm. Participants achieved a mean peak breath alcohol concentration (BrAC) of 81.18 mg% (SD = 24.96). Those with the OPRM1 118G variant (GA or GG genotypes) achieved significantly higher peak BrAC (M = 94.90 mg%, SD = 16.56) than those with the AA genotype (M = 74.46 mg%, SD = 25.36), reflecting a significantly greater number of alcohol requests among GA/GG participants. Eighty percent of GA/GG participants surpassed a threshold defining a laboratory analog of heavy alcohol exposure (80 mg%) compared with 46 percent of AA participants. Results indicated significant associations between subjective measures of alcohol sensitivity and CASE outcomes, although the pattern of findings differed across self-report measures. Subjective responses did not differ by OPRM1 status. These results offer further support for the feasibility of the CASE paradigm and provide initial evidence for an association of OPRM1 with alcohol self-administration in a human laboratory context.

Abstract
Subjective responses to alcohol are important determinants of drinking behavior and have been linked with risk for alcohol use disorders. However, few attempts have been made to examine proximal within-person associations among state changes in subjective responses and ongoing alcohol self-administration in the laboratory. This study disaggregated within- and between-person associations among subjective responses and alcohol self-administration, while also examining the mediating role of craving and the moderating role of trait impaired control over alcohol. Sixty young heavy drinkers (mean age = 19.90, SD = 0.86) completed self-report measures including the Impaired Control Scale, then participated in a 2-hr intravenous alcohol self-administration session using the Computer-Assisted Self-infusion of Ethanol (CASE) paradigm. Repeated assessments of subjective stimulation, subjective sedation, and craving were examined in relation to ongoing in-session self-administration, as indexed by breath alcohol concentration (BrAC) assessed 15 min later. Multilevel structural equation modeling was used to isolate within-person and between-person associations. The results showed few significant associations at the between-person level, except for a direct negative association between sedation and BrAC. At the within-person level, state fluctuations in stimulation were positively associated with both craving and subsequent BrAC, whereas state changes in sedation were negatively associated with craving and positively associated with BrAC. Within-person indirect associations from subjective stimulation and sedation to subsequent BrAC mediated via craving were statistically significant. Also, participants higher on impaired control showed stronger within-person associations between craving and greater subsequent BrAC. The results suggest that subjective responses to alcohol and craving have proximal associations with self-administration behavior, the strength of which is linked with trait impaired control over alcohol.

Abstract
BACKGROUND Subjective responses (SRs) to alcohol have been implicated in alcoholism etiology, yet less is known about the latent factor structure of alcohol responses. The aim of this study was to examine the factor structure of SR using a battery of self-report measures during a controlled alcohol challenge. METHODS Nontreatment seeking drinkers (N = 242) completed an intravenous alcohol challenge including the following SR measures: Biphasic Alcohol Effects Scale, Subjective High Assessment Scale, Profile of Mood States, Alcohol Urge Questionnaire, and single items assessing alcohol "Liking" and "Wanting." Ascending limb target breath alcohol concentrations were 0.02, 0.04, and 0.06, and descending limb target was 0.04 g/dl. Exploratory factor analyses were conducted separately on estimates of mean and dose responses on the ascending limb and on descending limb data. To examine the generalizability of this factor structure, these analyses were repeated in heavy drinkers (≥14 drinks/wk for men, ≥7 for women; n = 132) and light drinkers (i.e., nonheavy drinkers; n = 110). RESULTS In the full sample, a 4-factor solution was supported for ascending limb mean and dose responses and descending limb data representing the following SR domains: Stimulation/Hedonia, Craving/Motivation, Sedation/Motor Intoxication, and Negative Affect. This 4-factor solution was replicated in heavy drinkers. In light drinkers, however, SR was better summarized by a 3-factor solution where ascending mean and descending limb responses consisted of Stimulation/Hedonia, Craving/Motivation, and a general negative valence factor, and dose responses consisted of a general positive valence factor, Sedation/Motor Intoxication, and Negative Affect. CONCLUSIONS These findings suggest that SR represents a multifaceted construct with consistent factor structure across both ascending and descending limbs. Further, as drinking levels escalate, more defined Craving/Motivation and negative valence dimensions may emerge. Longitudinal studies examining these constructs are needed to further our understanding of SR as potentially sensitive to alcohol-induced neuroadaptation.

Abstract
Currently available pharmacological treatments for alcoholism have modest efficacy and high individual variability in treatment outcomes, both of which have been partially attributed to genetic factors. One path to reducing the variability and improving the efficacy associated with these pharmacotherapies may be to identify overlapping genetic contributions to individual differences in both subjective responses to alcohol and alcoholism pharmacotherapy outcomes. As acute subjective response to alcohol is highly predictive of future alcohol related problems, identifying such shared genetic mechanisms may inform the development of personalized treatments that can effectively target converging pathophysiological mechanisms that convey risk for alcoholism. The focus of this review is to revisit the association between subjective response to alcohol and the etiology of alcoholism while also describing genetic contributions to this relationship, discuss potential pharmacogenetic approaches to target subjective response to alcohol in order to improve the treatment of alcoholism and examine conceptual and methodological issues associated with these topics, and outline future approaches to overcome these challenges.

Alcohol challenge responses predict future alcohol use disorder symptoms: a 6-year prospective study. Biol Psychiatry 2014; 75:798-806.

Abstract
BACKGROUND Propensity for alcohol misuse may be linked to an individuals' response to alcohol. This study examined the role of alcohol response phenotypes to future drinking problems. METHODS One hundred four young heavy social drinkers participated in a within-subject, double-blind, placebo-controlled laboratory alcohol challenge study with 6-year follow-up. Participants were examined for subjective responses before and after receiving an intoxicating dose of alcohol (.8 g/kg) or a placebo beverage, given in random order. Follow-up was conducted in 5 waves over 6 years after the sessions to assess drinking behaviors and alcohol use disorder (AUD) symptoms. Retention was high with 98% (509 of 520) of possible follow-ups completed. RESULTS Greater sensitivity to alcohol, in terms of stimulation and rewarding effects (like, want more) and lower sensitivity to alcohol sedation predicted greater number of AUD symptoms through 6 years of follow-up. Cluster analyses revealed that for half the sample, increasing levels of stimulation and liking were predictors of more AUD symptoms with the other half divided between those showing like and want more and want more alone as significant predictors. CONCLUSIONS The findings extend previous findings and offer new empirical insights into the propensity for excessive drinking and alcohol problems. Heightened alcohol stimulation and reward sensitivity robustly predicted more alcohol use disorder symptoms over time associated with greater binge-drinking frequency. These drinking problems were maintained and progressed as these participants were entering their third decade of life, a developmental interval when continued alcohol misuse becomes more deviant.

Abstract
To the extent that craving serves to compel excessive drinking, it would be important to predict the intensity of an individual's craving over the course of a drinking episode. Previous research indicates that regular alcohol use (measured by the AUDIT) and the number of drinks individuals have already consumed that evening independently predict craving to drink (Schoenmakers & Wiers, 2010). The current study aims to replicate those findings by testing whether these same variables predict craving to drink in a sample of 1320 bar patrons in a naturalistic setting. In addition, we extend those findings by testing whether regular alcohol use and self-reported number of drinks consumed interact to predict craving, and whether gender independently predicts craving or interacts with other variables to predict craving. Results indicate that for men, AUDIT score alone predicted craving, whereas for women, AUDIT score and number of drinks consumed interacted to predict craving, with craving highest among women with either high AUDIT scores or relatively high consumption levels. Our findings have implications for targeted intervention and prevention efforts, as women who have a history of harmful alcohol use and consume several drinks in an evening might be at the greatest risk for continued alcohol consumption.

Abstract
BACKGROUND In 3 previously published works (Brumback et al., 2007, Drug Alcohol Depend 91:10-17; King et al., 2011a, Arch Gen Psychiatry 68:389-399; Roche and King, 2010, Psychopharmacology (Berl) 212:33-44), our group characterized acute alcohol responses in a large group of young, heavy binge drinkers (n = 104) across a variety of subjective, eye-tracking, and psychometric performance measures. METHODS The primary goal of the current study was to directly replicate prior findings of alcohol response in heavy social drinkers (HD) in a second independent cohort (n = 104) using identical methodology. A secondary goal was to examine the effects of family history (FH) of alcohol use disorders (AUD) on acute alcohol response in both samples. Participants attended 2 randomized laboratory sessions in which they consumed 0.8 g/kg alcohol or a taste-masked placebo. At pre- and post-drink time points, participants completed subjective scales, psychomotor performance and eye-movement tasks, and provided salivary samples for cortisol determination. RESULTS Results showed that the second cohort of heavy drinkers exhibited a nearly identical pattern of alcohol responses to the original cohort, including sensitivity to alcohol's stimulating and hedonically rewarding effects during the rising breath alcohol content (BrAC) limb, increases in sedation during the declining BrAC limb, a lack of cortisol response, and psychomotor and eye-tracking impairment that was most evident at peak BrAC. The magnitude and temporal pattern of these acute effects of alcohol in the second cohort were similar to the first cohort across all measures, with the exception of 3 eye-movement measures: pro- and antisaccade accuracy and antisaccade velocity. FH of AUD did not affect alcohol response in the first cohort, and this was replicated in the second cohort. CONCLUSIONS In sum, in 2 independent samples, we have demonstrated that HD display a consistent and reliable sensitivity to alcohol's subjective effects and impairment of eye-tracking and psychomotor performance, which is not affected by FH status. This acute alcohol response phenotype in heavy, frequent binge drinkers appears to be robust and reproducible.

Subjective response to alcohol among alcohol-dependent individuals: effects of the μ-opioid receptor (OPRM1) gene and alcoholism severity. Alcohol Clin Exp Res 2012; 37 Suppl 1:E116-24.

Abstract
BACKGROUND Subjective response to alcohol has been examined as a marker of alcoholism risk. The A118G single-nucleotide polymorphism (SNP) of the mu-opioid receptor (OPRM1) gene has been previously associated with subjective response to alcohol in heavy drinkers. This study seeks to extend the literature by examining the effect of OPRM1 genotype on responses to alcohol in a sample of alcohol-dependent individuals. A secondary aim of this study is to examine alcoholism severity as a predictor of subjective responses to alcohol. METHODS Nontreatment seeking problem drinkers (n = 295) were assessed in the laboratory for clinical dimensions of alcohol dependence. Following prospective genotyping, 43 alcohol-dependent individuals across the 2 genotype conditions (AA, n = 23 and AG/GG, n = 20) were randomized to 2 intravenous infusion sessions: 1 of alcohol (target breath alcohol concentration = 0.06 g/dl) and 1 of saline. Measures of subjective responses to alcohol were administered in both infusion sessions. RESULTS Alcohol-dependent G-allele carriers reported greater alcohol-induced stimulation, vigor, and positive mood, as compared to A-allele homozygotes. There was no genotype effect on alcohol-induced sedation or craving. There was a statistical trend-level severity × alcohol interaction such that individuals at higher levels of severity reported greater alcohol-induced tension reduction. CONCLUSIONS These results support the hypothesis that OPRM1 genotype moderates the hedonic effects of alcohol, but not the sedative and unpleasant effects of alcohol, in a sample of alcohol-dependent patients. Results are discussed in light of a clinical neuroscience framework to alcoholism.

Abstract
BACKGROUND The Biphasic Alcohol Effects Scale (BAES) is a reliable and valid 14-item measure of alcohol's acute stimulant and sedative effects, but its length may preclude use in research paradigms with time constraints on assessment. Here, we report further psychometric support for the 6-item Brief BAES (B-BAES) originally developed by our group in 2009. METHODS Two studies are included: the first study tested the B-BAES in an independent sample of young adult heavy social drinkers administered 0.8 g/kg alcohol in a laboratory challenge study (N = 104) to confirm the reliability and validity of the 6-item B-BAES. The second study compared the predictive validity of the B-BAES versus the BAES in a separate sample of 104 heavy drinkers who took part in a prospective laboratory alcohol challenge and follow-up study of drinking behaviors. RESULTS An item analysis demonstrated strong support across several intervals on the breath alcohol curve for the same 6 B-BAES items (energized, excited, up, sedated, slow thoughts, sluggish). Confirmatory factor analysis with the B-BAES demonstrated strong support for the same underlying structure as with the full BAES, and tests of internal consistency reliability were very strong to excellent. B-BAES subscale scores correlated highly with corresponding scores of the BAES and predicted binge-drinking frequency during a 2-year follow-up. CONCLUSIONS These results provide strong psychometric support to confirm use of the B-BAES in studies assessing alcohol's stimulant and sedative properties. The B-BAES may be a useful new tool to enhance the scope of future research assessing alcohol's biphasic effects, particularly in paradigms when time and concise measurement are priorities.
