Neuroinflammation is implicated in the development and maintenance of alcohol use disorder (AUD) and neuroimmune therapeutics show promise in treating AUD. Proinflammatory signaling contributes to progressive elevations in the dysfunction of mood and alcohol craving. The current study sought to examine potential biobehavioral mechanisms of neuroimmune modulation in AUD under experimental conditions. In a community sample of individuals with AUD who completed a placebo-controlled crossover trial of ibudilast, we tested the effect of ibudilast on the relationship between mood states and alcohol craving. Multilevel modeling analyses tested the hypothesis that ibudilast would moderate the effect of positive and negative mood states on alcohol craving during stress and cue exposures. Results revealed that after stress-induction, participants' feelings of depression and happiness were more strongly predictive of their craving for alcohol while taking ibudilast as compared with placebo (

AIMS: The current study examined the association between pain catastrophizing and alcohol cue-elicited brain activation in individuals with alcohol use disorder (AUD). METHODS: Non-treatment seeking heavy drinkers with AUD (n = 45; 28 males) completed self-report measures of pain catastrophizing and alcohol use/problems as part of a clinical trial of the neuroimmune modulator ibudilast. Participants were randomized to either placebo (n = 25) or ibudilast (n = 20) and completed an functional magnetic resonance imaging (fMRI) scan to assess neural activation to alcohol cues 1week into the medication trial. Multiple linear regression examined whether pain catastrophizing predicted cue-induced activation in a priori regions of interest, namely the dorsal and ventral striatum (VS). An exploratory whole-brain analysis was conducted to assess the relationship between pain catastrophizing and neural alcohol cue reactivity. RESULTS: Pain catastrophizing predicted greater cue-induced activation in the dorsal (b = 0.006; P = 0.03) but not VS controlling for medication. Pain catastrophizing was positively associated with neural activation to alcohol cues in regions including the bilateral thalamus, left precuneus and left frontal pole. CONCLUSION: Greater pain catastrophizing is associated with greater cue-induced neural activation in brain regions sub-serving habits and compulsive alcohol use. These findings provide initial support for a neural mechanism by which pain catastrophizing may drive alcohol craving among individuals with AUD.

The study examined the effect of GTS-201, a low-molecular weight mimetic of brain-derived neurotrophic factor (BDNF) loop 2, on persistent alcohol craving in outbred male and female albino rats with ethanol preference score ~50% developed in the free choice paradigm between 10% ethanol and water over 24 weeks. Both single and subchronic (5 days) injections of GTS-201 in a daily dose of 5 μg/kg reduced alcohol deprivation effect in female, but not in male rats. The possibility of in vivo sex-dependent regulation of modeled alcohol craving with a low-molecular-weight dipeptide mimetic of BDNF loop 2 was demonstrated and sex-related differences in this effect were revealed

OBJECTIVES: Observational studies suggest emotion regulation (ER) as a potential treatment target for problematic college drinking. The primary aim of this laboratory study was to determine whether trait ER strategies would moderate the impact of negative affect induction on alcohol craving in college drinkers. METHODS: Participants were randomly assigned to a neutral (n = 74) or a negative affect induction (n = 76) and reported their craving after the affect inductions. RESULTS: Greater use of drinking to cope and less use of cognitive reappraisal predicted greater alcohol craving after the negative affect induction, but not after the neutral condition. In contrast, emotion suppression did not predict alcohol craving in either condition. CONCLUSION: Our results highlight the role of ER tendencies — particularly the benefits of cognitive reappraisal — on alcohol craving when experiencing emotional distress. Therefore, ER strategies may be an important target for college drinkers to prevent and reduce problematic drinking.

The primary aim is to replicate the finding that experimentally-induced state anxiety influences alcohol choice, in an observational study of naturally-occurring state anxiety. The secondary aim is to test the association between state anxiety and alcohol craving.

This project aims to investigate the effects of state anxiety on alcohol-related behaviours (i.e., alcohol craving, alcohol choice and approach-avoidance tendencies), and explore whether effects differ by drinking-to-cope status using the 7.5% CO2 model of anxiety.

The Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS) are two motivational systems that are involved in behavioral and emotional reactions to stimuli. The BIS is thought to be activated by conflicting stimuli and is responsible for the defensive approach to dangerous or unpleasant situations, while the BAS is thought to be activated by cues for reward or escape from punishment (Vecchione, Ghezzi, Alessandri, Dentale, & Corr, 2021). These two behavioral systems can be operationalized and measured by the BIS/BAS scale, a trait scale consisting of 24 statements, each scored on a scale of 1 ("very true for me") to 4 ("very false for me") (Carver & White, 1994). Several studies have used this scale to look at the BIS and the BAS in the context of alcohol use disorder (AUD) (Franken, Muris, & Georgieva, 2006; Hamilton et al., 2012; Rieser et al., 2019; Sprah & Novak, 2008). Most of the literature has studied this scale in relation to alcohol consumption; however, few studies have investigated the relationship between these two systems and alcohol craving. This is an important aspect because, for example, studies have found that craving plays an important role in alcohol seeking and consummatory behaviors and higher craving may be a risk factor for relapse, as previously reviewed (Addolorato, Leggio, Abenavoli, & Gasbarrini, 2005; Cavicchioli, Vassena, Movalli, & Maffei, 2020; Seo & Sinha, 2014). Understanding the correlates of alcohol cravings could help provide insight into individual-based prevention and treatment methods for AUD.

Objective: Racial discrimination is a known risk factor for alcohol-related outcomes among young Black American adults. However, vicarious racial discrimination's associations with alcohol-related outcomes and the role of racial identity in these associations remain unknown. This within-subject experiment study tested whether associations of vicarious racial discrimination with alcohol craving and attentional bias differed by three components of racial identity (centrality, private regard, and public regard). Method: Black young adult, at-risk drinkers (N = 51; Mage = 21 [SD = 3.02]; 60% female) completed two vicarious racial discrimination conditions (manipulated by video) followed by alcohol craving and attentional bias tasks. Results: Associations of vicarious discrimination with alcohol craving were exacerbated by high centrality and buffered by high private regard, but did not differ by public regard. No associations of vicarious discrimination with alcohol attention bias were found. Conclusion: Findings highlight the important role of Black racial identity in within-group differences in the impact of vicarious racial discrimination on select implicit indicators of alcohol risk among Black young adults.

Increasing evidence implicates sleep/circadian factors in alcohol use; however, the role of such factors in alcohol craving has received scant attention. Prior research suggests a 24-hour rhythm in related processes (e.g., reward motivation), but more research directly investigating a rhythm in craving is needed. Moreover, prior evidence is ambiguous whether such a rhythm in alcohol craving may vary by sleep/circadian timing. To examine these possibilities, 36 late adolescents (18–22 years of age; 61% female) with regular alcohol use but without a current alcohol use disorder were recruited to complete smartphone reports of alcohol craving intensity six times a day for two weeks. During these two weeks, participants wore wrist actigraphs and completed two in-lab assessments (on Thursday and Sunday) of dim light melatonin onset (DLMO). Average actigraphically-derived midpoint of sleep on weekends and average DLMO were used as indicators of sleep and circadian timing, respectively. Multilevel cosinor analysis revealed a 24-hour rhythm in alcohol craving. Findings across the sleep and circadian timing variables converged to suggest that sleep/circadian timing moderated the 24-hour rhythm in alcohol craving. Specifically, people with later sleep/circadian timing had later timing of peak alcohol craving. These findings add to the growing evidence of potential circadian influences on reward-related phenomena and suggest that greater consideration of sleep and circadian influences on alcohol craving may be useful for understanding alcohol use patterns and advancing related interventions.

Negative affect may be related to alcohol-related patterns (e.g., craving and problematic alcohol use). Distress intolerance and positive and negative alcohol-related metacognitions may be underlying mechanisms in this link. This study aimed to evaluate the effect of negative affect including depressive, anxious, and stress symptoms on alcohol craving and problematic alcohol use via the paths of distress tolerance and both positive and negative alcohol-related metacognitions. Three hundred men with problematic alcohol use during the abstinence phase completed psychological and clinical measures. Results showed that craving and negative alcohol metacognitions mediated the relationship between negative affect and problematic alcohol use. Negative affect had a direct and positive effect on craving and indirect effect via distress intolerance and positive alcohol metacognitions. In turn, distress intolerance and positive alcohol metacognitions indirectly and positively affected problematic alcohol use via craving. The study indicates that distress tolerance and distinct alcohol metacognitions may be differently related to various patterns of alcohol-related problems, such that alcohol drinkers with high levels of negative affect, distress intolerance, and positive alcohol metacognitions show higher levels of craving, while high negative affect in relation to high negative alcohol metacognitions and alcohol craving is related to the perpetuation of alcohol use or problematic alcohol use.

Introduccion El deterioro del control sobre el consumo del alcohol se ha mencionado con frecuencia en diversas descripciones teoricas relativas al uso nocivo y es un criterio clinico del DSM para el trastorno por uso de alcohol. Las diferencias en la frecuencia con que se admite el deterioro del control se han considerado como un reflejo de la gravedad del problema. Ademas, se ha postulado que la capacidad de poner un limite al consumo de alcohol puede estar mediada por el deseo de consumirlo (craving). Objetivo En este estudio se abordo la relacion entre el deterioro del control, el autoreporte del craving y la gravedad de la dependencia del alcohol en un grupo de bebedores fuertes. Metodo Se realizo un analisis de clases latentes usando las dimensiones del deterioro del control (control percibido, control fallido e intento de control) de 208 bebedores fuertes. Para determinar si las clases identificadas podian representar diferentes formas de gravedad del trastorno se contrasto el modelo mas adecuado con las puntuaciones de la Escala de Dependencia del Alcohol. Ademas, se evaluo la relacion entre los criterios de deterioro del control (utilizando la Escala de Control Deficiente, ECD) y el craving. Resultados Identificamos una solucion de tres clases basada en la gravedad del deterioro de control. En esa solucion se identifico una relacion con el aumento graduado de las puntuaciones de craving y la gravedad de la dependencia entre las clases. Solo los elementos de la ECD que comprenden el control percibido y parcialmente los relacionados con el control fallido, pero no los que evaluan el intento de control, distinguieron el gradiente entre las clases latentes. Discusion y conclusion Este estudio proporciona mas apoyo a la propuesta de un continuum unidimensional de gravedad entre los usuarios de alcohol y refuerza la relacion teorica entre el fenomeno de deterioro del control y el craving

Alexithymia is a vulnerability factor for physical and mental illness that can significantly influence the daily function of alcohol-dependent patients. The aim of this study was to examine the indirect effect of obsessive thoughts and compulsive behaviors involving alcohol craving on the relationship between alexithymia, quality of life (QoL) of psychological well-being and health status. Three hundred and eighty-one outpatients (263 males and 118 females) in treatment for alcohol dependence completed self-report measures of alexithymia, alcohol craving, GHQ-28 (QoL-psychological well-being) and SF-36 (QoL-health status). Males scored significantly higher than females on aspects of alexithymia, and females reported significantly higher levels of alcohol craving. Path analysis showed an indirect effect of alcohol craving on the relationship between alexithymia, QoL-psychological well-being and self-reported QoL-health status for males only. The current study provides important new information about impaired self-reported health status and well-being among male alcohol-dependent treatment seekers with alexithymia.

Background In-laboratory drinking sessions that allow direct assessment of drinking and craving are an emerging method for testing novel pharmacotherapy compounds and behavioral interventions for alcohol use disorders. Despite wide implementation, limited evidence supports the concordance between drinking in the laboratory and in a natural setting. This study examined the relationship between self-reports of drinking prior to and drinking and craving during an alcohol drinking paradigm (ADP). Methods Participants were adult heavy drinkers (N = 64) who participated in a pharmacotherapy study. Participants completed self-report alcohol assessments and a baseline ADP session prior to any medication administration. Alcohol craving was assessed during priming and ad lib ADP phases. Outcomes were the associations of total drinks consumed in-laboratory and summary drinking measures for the 30 days prior to the ADP and reports of maximum drinks (past year and lifetime). Additional outcomes were the association of self-reported drinking and alcohol craving during the ADP and the concordance between self-report and ADP World Health Organization (WHO) drinking classifications. Results Number of drinking days, average drinks per drinking occasion, and lifetime and past-year maximum drinks were all related to drinking in the laboratory. Heavy drinking days were not related to drinking in the laboratory but were associated with ADP craving. Alcohol craving was also associated with other measures of self-reported drinking. There was also a significant association between WHO drinking risk classification and in-laboratory drinking. Conclusions The observed relationships between self-reported drinking and drinking in-laboratory across drinking indices suggest that in-laboratory alcohol consumption may reflect participants' real-world alcohol consumption, supporting the value of laboratory-based drinking paradigms. The demonstrated relationship with self-reported drinking and ADP alcohol craving further supports the value of such paradigms to model key drinking predictors. These results provide support for the validity of laboratory-based paradigms to accurately reflect participants' recent drinking levels.

Alcohol consumption is associated with gut dysbiosis, increased intestinal permeability, endotoxemia, and a cascade that leads to persistent systemic inflammation, alcoholic liver disease, and other ailments. Craving for alcohol and its consequences depends, among other things, on the endocannabinoid system. We have analyzed the relative role of central vs. peripheral cannabinoid CB1 receptors (CB1R) using a “two-bottle” as well as a “drinking in the dark” paradigm in mice. The globally acting CB1R antagonist rimonabant and the non-brain penetrant CB1R antagonist JD5037 inhibited voluntary alcohol intake upon systemic but not upon intracerebroventricular administration in doses that elicited anxiogenic-like behavior and blocked CB1R-induced hypothermia and catalepsy. The peripherally restricted hybrid CB1R antagonist/iNOS inhibitor S-MRI-1867 was also effective in reducing alcohol consumption after oral gavage, while its R enantiomer (CB1R inactive/iNOS inhibitor) was not. The two MRI-1867 enantiomers were equally effective in inhibiting an alcohol-induced increase in portal blood endotoxin concentration that was caused by increased gut permeability. We conclude that (i) activation of peripheral CB1R plays a dominant role in promoting alcohol intake and (ii) the iNOS inhibitory function of MRI-1867 helps in mitigating the alcohol-induced increase in endotoxemia.

Introduction: Our study investigated whether discrimination affects psychologi-cal/physiological stress and alcohol craving. Method: Participants (N = 92) were asked to recall and write about (a) a neutral, (b) a negative, or (c) a discriminatory experience in the past and then completed a cue-reactivity procedure assessing their alcohol craving. In addition, we assessed levels of perceived stress before and after the discrimination manipulation, chronic substance use and craving, prior perceived discrimination, and strength of racial/ethnic identity. Results: Results revealed a small effect in which the discrimination condition increased alcohol cue-elicited craving relative to the other conditions. Chronic craving moderated effects of discrimination on cortisol levels. Self-reported stress levels were increased in the discrimination and negative memory conditions relative to baseline. Strength of racial identity served as a protective factor for substance abuse in those who reported chronic high levels of discrimination. Discussion: We discussed the direct link established between acute exposure to discrimination and craving, and experimental evidence for the relationship between discrimination and self-reported stress, but also addressed potential limitations of this work. It is further discussed how some individual differences factors (e.g., chronic craving) predict physiological stress in discriminatory settings. This work underscored the role of racial identity as a protective factor against alcohol abuse in individuals reporting high levels of discrimination.

AimsAlcohol use disorder is highly heterogeneous. One approach to understanding this heterogeneity is the identification of drinker subtypes. A candidate classification consists of reward and relief subtypes. The current study examines a novel self-report measure of reward, relief, and habit drinking for its clinical correlates and subjective response (SR) to alcohol administration.MethodsNon-treatment-seeking heavy drinkers (n = 140) completed the brief reward, relief, habit drinking scale (RRHDS). A subset of this sample (n = 67) completed an intravenous alcohol administration. Individuals were classified into drinker subtypes. A crowdsourced sample of heavy drinkers (n = 187) completed the RRHDS and a validated reward relief drinking scale to compare drinking classification results.ResultsThe majority of the sample was classified as reward drinkers (n = 100), with fewer classified as relief (n = 19) and habit (n = 21) drinkers. Relief and habit drinkers reported greater tonic alcohol craving compared to reward drinkers. Reward drinkers endorsed drinking for enhancement, while relief drinkers endorsed drinking for coping. Regarding the alcohol administration, the groups differed in negative mood, such that relief/habit drinkers reported a decrease in negative mood during alcohol administration, compared to reward drinkers. The follow-up crowdsourcing study found a 62% agreement in reward drinker classification between measures and replicated the tonic craving findings.ConclusionsOur findings suggest that reward drinkers are dissociable from relief/habit drinkers using the brief measure. However, relief and habit drinkers were not successfully differentiated, which suggests that these constructs may overlap phenotypically. Notably, measures of dysphoric mood were better at detecting group differences than measures capturing alcohol’s rewarding effects.

Background Alcohol craving, or the desire to drink alcohol, has been identified as a key experience preceding alcohol use. Alcoholics Anonymous has long claimed that individuals can allay alcohol cravings by eating sweets. Empirical tests of this strategy are limited to a few preclinical studies in rats, and there is no existing experiment testing the acute effect of eating sweets on alcohol cravings in humans. Purpose The current study sought to experimentally test the acute effect of eating sweets on alcohol cravings in a sample with at-risk drinking. Methods After being exposed to an alcohol cue, individuals with at-risk drinking (N = 150) were randomly assigned to eat sweets (n = 60), eat calorie-equivalent bland food (n = 60), or watch a video (n = 30). Caloric amounts were manipulated. Individuals with at-risk drinking were then exposed to a second alcohol cue. Changes in alcohol cravings from after the first to after the second alcohol cue were measured via visual analog scale and heart rate. Results There were no significant between-group differences in changes in alcohol cravings. Caloric amounts did not modify effects. Conclusions Experimental findings did not provide evidence to support the clinical lore that eating sweets can reduce alcohol cravings, albeit only acutely and for those with at-risk drinking. Other empirically supported strategies for managing alcohol cravings (e.g., pharmacotherapies, mindfulness) could instead be promoted.

BACKGROUND: Alcohol craving is common among adolescents, stronger among those with more alcohol-related problems, and predicts drinking levels in their daily lives. Yet, the conditions that predict momentary changes in craving in real time among adolescents remain unclear. OBJECTIVES: This study examined interactive effects of momentary risk-taking propensity and affect on adolescents’ alcohol craving by leveraging ecological momentary assessment (EMA) methods. METHODS: Participants were 29 adolescents ages 15-19 years (55% female; 69% White; 10% Black; 17% Hispanic); 45% met criteria for alcohol dependence. Following a laboratory session that captured self-report and behavioral assessments, including the well-established Balloon Analogue Risk Task (BART: Lejuez et al., 2002), participants completed multiple daily assessments of alcohol craving, positive and negative affect, and risk propensity for approximately one week. Momentary risk propensity was captured in real-world settings via an EMA behavioral task (“Balloon Game”). RESULTS: Mixed-effects models with EMA reports (Level 1) nested within participants (Level 2) revealed the majority (74%) of variability in “Balloon Game” performance was due to within-person, momentary, fluctuations. Greater momentary positive affect predicted increased alcohol craving, but only when participants exhibited heightened risk-taking propensity. Negative affect did not influence the relation between momentary risk-taking and craving. CONCLUSIONS/IMPORTANCE: Momentary fluctuations in positive affect predicted acute increases in craving but only in moments when adolescents demonstrated higher levels of risk-taking propensity, as captured with an EMA-delivered behavioral task. Momentary risk-taking assessments offer new avenues to substantiate dominant theories on the driving mechanisms of craving and alcohol use among adolescents.

Contrary to most theories of alcohol craving, which only consider desires to use, the Ambivalence Model of Craving (AMC) conceptualizes craving bi-dimensionally as the concurrent desires to consume (approach) and desires not to consume (avoid) alcohol. Consistent with the AMC, the Approach and Avoidance of Alcohol Questionnaire (AAAQ) is a 14-item self-reported measure designed to assess alcohol approach and avoidance inclinations. Scores on the AAAQ have been shown to have high reliability and validity in clinical and college student populations, with a two-factor solution emerging in clinical samples of patients with Alcohol Use Disorders (AUDs) and a three-factor solution in samples of college students. However, despite a number of studies examining the use of the AAAQ in clinical and college student samples, to the best of our knowledge there have not been any psychometric evaluations of the AAAQ in community samples. The current study examined the psychometric properties of the AAAQ by examining the factor structure in a community sample (N = 537). Consistent with the results of previous studies utilizing non-clinical samples, a three-factor solution fit the data best and was invariant across gender. Additionally, all three factors were significantly associated with variables of drinking behavior. These results suggest that the AAAQ provides valid and reliable scores that measure approach and avoidance inclinations in community populations.

Background Despite a rich literature on human laboratory paradigms of subjective response (SR) to alcohol, craving for alcohol, and alcohol self-administration, few studies have examined the interplay across these 3 constructs. The present study addresses this gap in the literature by examining the interplay between SR, craving, and self-administration in the human laboratory. Methods Data were culled from a medication study (NCT02026011) in which heavy drinking participants of East Asian ancestry completed 2 double-blinded and counterbalanced experimental sessions. In each experimental session, participants received a priming dose of intravenous (IV) alcohol to a target breath alcohol concentration (BrAC) of 0.06 g/dl and measures of SR (stimulation and sedation) and alcohol craving were collected across rising BrACs. The IV alcohol challenge was immediately followed by a 1-hour alcohol self-administration period. Results Mixed model analyses found a positive and significant relationship between the slope of stimulation and the slope of craving during the alcohol challenge. The relationship between sedation and craving, however, was not significant. The slope of craving during the alcohol challenge significantly predicted a higher number of mini-drinks consumed and lower latency to first drink. Further, mediation analyses found that craving was a significant mediator of the relationship between stimulation and total number of mini-drinks consumed, but the same pattern was not found for sedation. Conclusions Insofar as alcohol self-administration represents the end point of interest for a host of experimental and clinical research questions, the present study suggests that alcohol craving represents a more proximal predictor of self-administration than measures of alcohol-induced stimulation. It is recommended that human laboratory models interpret measures of SR and craving in light of their relative predictive utility for drinking outcomes.

Aims Replicate the previously reported association of elevated alcohol craving, measured by Penn Alcohol Craving Scale (PACS) during residential treatment, with post-treatment relapse and explore whether elevated craving scores 3 months post-treatment are also associated with subsequent relapse. Methods Alcohol craving was assessed with the PACS on admission and at several time points post-treatment in 190 subjects with DSM-IV diagnosis of alcohol dependence admitted to residential treatment. Data about relapse to any drinking (primary outcome measure) was collected at 3, 6, 9 and 12 months after treatment. Cox regression models were used to determine whether PACS scores were associated with relapse. Statistical models were adjusted for meaningful demographic and clinical covariates. Results Follow-up data was available for 149/190 (78%) of subjects. Elevated PACS scores at discharge were associated with increased relapse risk within the first 3 and 12 months after discharge (P = 0.032 and P = 0.045, respectively). Elevated PACS scores at 3 months were associated with increased risk of subsequent relapse within 12 months after treatment in contacted subjects (P = 0.034) and in the intent-to-treat analysis (P = 0.0001). Conclusions Our findings indicate strong association of post-treatment relapse with elevated alcohol craving measured at treatment completion and at 3 months after treatment and justify the use of this measure to guide relapse-prevention efforts.

Background Court-mandated substance use disorder (SUD) treatment, compared to nonmandated treatment, has been associated with increased retention and completion. However, due to limitations of previous studies, whether child protective services (CPS) and criminal justice (CJ) mandated treatment improve treatment completion and retention among women in residential treatment remains unclear. Purpose This study investigated differences in treatment completion and progress based on three clinical discharge outcomes (i.e., completer, noncompleter with significant progress, and noncompleter without significant progress). We hypothesized that women mandated by (1) CJ will have a better treatment discharge outcome (i.e., treatment completer and noncompleter with satisfactory progress) compared to women who are CPS mandated; (2) CPS will have a better treatment discharge outcome (i.e., treatment completer and noncompleter with satisfactory progress) compared to nonmandated women. Methods Study staff conducted multinomial logistic regression analyses on data for a diverse sample of 161 women mandated or nonmandated (CJ: N = 71, CPS: N = 66, nonmandated: N = 24) into residential SUD treatment to determine each group's clinically defined treatment discharge outcomes while controlling for covariates. Results Multinomial logistic regression analyses revealed that being mandated by the CJ system predicted being a treatment completer compared to those who were CPS mandated (RR = 9.88, p = .009). The study found no differences in discharge status of completer without satisfactory progress between those who were CPS mandated and those who were CJ mandated or nonmandated. For women mandated by the CPS system compared to nonmandated women, the risk of being a treatment completer relative to noncompleters with satisfactory progress was not significant (RR = 1.08, p = .897). Analyses showed that being mandated by the CJ system predicted an improved clinically defined discharge outcome of treatment completer compared to women who were nonmandated to treatment (RR = 10.74, p = .016). In several of the models, drug and alcohol craving was associated with increased odds of being a noncompleter of treatment without satisfactory progress. Conclusions This study demonstrates that improved treatment completion and discharge status cannot be assumed based solely on being mandated by the CJ or CPS systems. As evidenced by variability in treatment discharge outcomes within and among referral groups, the paper suggests directions for future research.

Aims: Attentional bias (AB), alcohol craving, and anxiety have important implications in the development and maintenance of alcohol use disorder (AUD). The current study aims to test the effectiveness of a Virtual Reality Cue-Exposure Therapy (VR-CET) to reduce levels of alcohol craving and anxiety and prompt changes in AB toward alcohol content.Method: A 49-year-old male participated in this study, diagnosed with severe AUD, who also used tobacco and illicit substances on an occasional basis and who made several failed attempts to cease substance misuse. The protocol consisted of six VR-CET booster sessions and two assessment sessions (pre- and post-VR-CET) over the course of 5 weeks. The VR-CET program consisted of booster therapy sessions based on virtual reality (VR) exposure to preferred alcohol-related cues and contexts. The initial and final assessment sessions were focused on exploring AB, alcohol craving, and anxiety using paper-and-pencil instruments and the eye-tracking (ET) and VR technologies at different time points.Results: Pre and post assessment sessions indicated falls on the scores of all instruments assessing alcohol craving, anxiety, and AB.Conclusions: This case report, part of a larger project, demonstrates the effectiveness of the VR-CET booster sessions in AUD. In the post-treatment measurements, a variety of instruments showed a change in the AB pattern and an improvement in craving and anxiety responses. As a result of the systematic desensitization, virtual exposure gradually reduced the responses to significant alcohol-related cues and contexts. The implications for AB, anxiety and craving are discussed.

Introduction Alcohol cravings can predict relapse in persons with alcohol use disorder (AUD). Consuming sweets is a commonly recommend strategy to quell alcohol cravings in early recovery from AUD, yet research is equivocal on whether consuming sweets mitigates alcohol cravings or relapse risk. The current study used ecological momentary assessment (EMA) data to examine real-time alcohol cravings, sweet cravings, and consumption of sweets among adults in early recovery from AUD. Methods We used EMA methods to follow 25 adults (n = 14 women, 56%; M. age 40, S.D. 10.68) recently discharged from a partial hospitalization program for AUD for 21 days. Prompts were sent to the participants for completion four times per day via a mobile app. EMA data were disaggregated prior to analysis to examine between- and within-person effects. A series of three mixed linear models tested: 1) the contemporaneous effect of sweet and alcohol cravings, 2) alcohol cravings predicting sweet consumption later in the day, and 3) sweet consumption predicting alcohol craving later in the day. Results The results of the first model revealed alcohol cravings were associated with sweet cravings early in recovery. In the second model, no effect occurred between alcohol cravings earlier in the day predicting sweet consumption later in the day. The third model suggested consuming sweets earlier in the day predicted higher alcohol cravings later in the day. Discussion Sweet craving and consumption are associated with alcohol cravings among adults in early recovery from AUD. These findings suggest consuming sweets may increase alcohol cravings. If future studies can replicate this result, consuming sweets in early recovery may emerge as a potential risk for relapse in this population.

The identification of variables that can modulate the efficacy of cue exposure using virtual reality (VR) is crucial. This study aimed to explore determinant variables of cue-elicited alcohol craving and perceived realism (PR) of environments and alcoholic beverages during a VR cue-exposure session among alcohol use disorder (AUD) outpatients. A prospective cohort study was conducted amongst 72 outpatients with AUD from a clinical setting. Alcohol craving experienced during VR exposure and PR of virtual environments and alcoholic drinks were evaluated after a VR session of exposure to alcohol-related contexts and cues. Sociodemographic, psychological and consumption characteristics were examined as possible predicting variables. Multiple linear regression analyses showed that the AUD severity and PR of beverages were predictors of cue-elicited alcohol craving. Educational level, PR of beverages and age were predictors of the PR of VR environments. In relation to the PR of VR beverages, cue-elicited alcohol craving and the PR of environments were predictors. A simple mediational model was also performed to analyze the influence of the PR of beverages on the relationship between the AUD severity and alcohol craving experienced during VR exposure: an indirect or mediational effect was found. PR of alcoholic beverages was (1) a key predictor of the PR of VR environments (and vice versa) and the alcohol craving (and vice versa) experienced during VR cue-exposure sessions using ALCO-VR software among AUD patients and (2) a mediator between AUD severity and cue-elicited alcohol craving.

Aim We sought to elucidate whether stress, peers, and in vivo (i.e., direct) alcohol cues elicit alcohol craving in daily life among adolescents and to test whether individual variation in working memory function and biological sex alters these associations. Methods We leveraged ecological momentary assessment (EMA) to examine momentary associations between stress, peers, and direct alcohol cues with craving, assessed as “urge to drink alcohol,” among 86 male (51.2 %) and female (48.8 %) frequent drinkers (i.e., two or more drinking days per week). Participants were ages 14–24 years (M = 20.7 years, SD = 2.1). Participants completed EMA throughout the day for about one week prior to randomization to a treatment condition for an AUD clinical trial. Pre-registered, secondary analyses focused on craving for assessments when adolescents were not drinking, and assessments occurring after drinking on drinking days were removed. Working memory performance was assessed in the laboratory via the Memory for Words subtest of the Woodcock-Johnson III Tests of Cognitive Abilities. Results Craving was heightened at more stressful moments and when adolescents were with their peers and in the presence of direct alcohol cues. Working memory function was not related to craving but altered the relation of momentary stress, peers, and cues with craving once biological sex-related differences were considered. Females generally had lower craving than males, but working memory function served to buffer against stress-induced craving for males. Conclusions Higher working memory function buffered the in-the-moment relation of stress with alcohol craving for males but not females.

Alexithymia is a vulnerability factor for physical and mental illness that can significantly influence the daily function of alcohol-dependent patients. The aim of this study was to examine the indirect effect of obsessive thoughts and compulsive behaviors involving alcohol craving on the relationship between alexithymia, quality of life (QoL) of psychological well-being and health status. Three hundred and eighty-one outpatients (263 males and 118 females) in treatment for alcohol dependence completed self-report measures of alexithymia, alcohol craving, GHQ-28 (QoL-psychological well-being) and SF-36 (QoL-health status). Males scored significantly higher than females on aspects of alexithymia, and females reported significantly higher levels of alcohol craving. Path analysis showed an indirect effect of alcohol craving on the relationship between alexithymia, QoL-psychological well-being and self-reported QoL-health status for males only. The current study provides important new information about impaired self-reported health status and well-being among male alcohol-dependent treatment seekers with alexithymia.

Recent evidence indicates that the United States is facing a public health crisis of alcohol misuse and alcohol use disorder (AUD), which has been fueled in part by dramatic rises in binge and heavy drinking and prevalence of AUD in women. Historically, alcohol misuse and AUD have been more prevalent in men than in women. However, recent evidence on data from the past decade shows increases in AUD prevalence rates that are associated with substantially higher binge and heavy drinking and AUD prevalence in women compared to men. This paper first addresses the key roles of stress, trauma, childhood maltreatment, negative affect, and mood and anxiety disorders; sex differences in the presentation of these psychosocial and psychological factors; and their contributions to alcohol misuse, escalation to binge and heavy drinking, and transition to AUD in women. Also examined are potential central and peripheral biological mechanisms by which stressors and traumatic experiences, as well as chronic stress states—including depression and anxiety—may facilitate differential pathways to alcohol misuse, escalation, and transition to AUD in women. Finally, this paper discusses major gaps in the literature on sex differences in these areas as well as the need for greater research on sex-specific pathways to alcohol misuse and transition to AUD, so as to support a more comprehensive understanding of AUD etiology and for the development of new strategies for prevention and treatment of alcohol misuse and AUD in women.

Longer periods of abstinence are shown to enhance response to alcohol cues among alcohol-dependent animals(1–4) and humans(5,6), a phenomenon described as “incubation of craving.” The present work examined the effects of days since last drink on general craving and alcohol-cued craving as it occurs in daily life and explored whether effects were influenced by age and dependence. METHODS: Three samples were combined to include 266 drinkers ranging in age from 14 to 67 years recruited from the community; about half (59.4%) met criteria for alcohol dependence. Drinkers used handheld electronic devices to rate their subjective alcohol craving (assessed as “urge to drink”) and situational context (e.g., presence of visible alcohol cues) at non-drinking times in daily life, with days since last alcohol use culled from timeline follow-back interviews and real-world reports. RESULTS: Drinkers at the lower end of the age range in this sample reported greater intensification of craving with more days of continuous abstinence than drinkers at the upper end of the age range. Age was not related to incubation of cue-elicited craving, in specific, however. For drinkers with dependence, craving when in the presence of visible alcohol cues intensified with more days of continuous abstinence, suggesting craving incubation. CONCLUSIONS: This study builds from important foundational work to demonstrate that incubation of cue-elicited craving occurs in dependent drinkers and applies regardless of age. Inasmuch as craving is a motivational drive that maintains alcohol use(7), understanding factors that influence craving in daily life holds promise for improving clinical care.

BACKGROUND Anger and anger-related traits have been related to alcohol use in both cross-sectional and prospective studies. However, only a small number of studies have experimentally manipulated anger to examine whether the manipulation of anger influences alcohol craving or the relative reinforcing value of alcohol. METHODS Participants (N = 231) recruited through Amazon's MTurk were randomly assigned to a provocation condition or a neutral condition prior to completing both the Alcohol Purchase Task and a self-report measure of alcohol craving. Linear regression analyses were conducted to examine the effects of the anger induction, trait hostility, frequency of alcohol use in the past month, and relevant demographic characteristics (gender, age, income) on alcohol craving and indices of alcohol demand. RESULTS Participants assigned to the provocation condition had greater PMax (B = 0.17, p = 0.012) and breakpoint (B = 0.18, p = 0.006) values, less elastic demand (B = -0.15, p = 0.020), and lower drinking intensity (B = -0.14, p = 0.025) than participants assigned to the neutral condition. Trait hostility was positively related to OMax (B = 0.22, p = 0.001), intensity of demand (B = 0.27, p

The efficacy of short-term treatment with mifepristone (MIFE), a high-affinity, nonselective glucocorticoid receptor antagonist, to reduce ethanol drinking was tested in a rhesus macaque model. Stable individual daily ethanol intakes were established, ranging from 1.6 to 4.0 g/kg per day (n = 9 monkeys). After establishment of chronic ethanol intake, a MIFE dosing regimen that modeled a study of rodent drinking and human alcohol craving was evaluated. Three doses of MIFE (17, 30, and 56 mg/kg per day) were each administered for four consecutive days. Both 30 and 56 mg/kg decreased ethanol intake compared with baseline drinking levels without a change in water intake. The dose of 56 mg/kg per day of MIFE produced the largest reduction in ethanol self-administration, with the average intake at 57% of baseline intakes. Cortisol was elevated during MIFE dosing, and a mediation analysis revealed that the effect on ethanol drinking was fully mediated through cortisol. During a forced abstinence phase, access to 1.5 g/kg ethanol resulted in relapse in all drinkers and was not altered by treatment with 56 mg/kg MIFE. Overall, these results show that during active drinking MIFE is efficacious in reducing heavy alcohol intake in a monkey model, an effect that was related to MIFE-induced increase in cortisol. However, MIFE treatment did not eliminate ethanol drinking. Further, cessation of MIFE treatment resulted in a rapid return to baseline intakes, and MIFE was not effective in preventing a relapse during early abstinence. SIGNIFICANCE STATEMENT: Mifepristone reliably decreases average daily ethanol self-administration in a nonhuman primate model. This effect was mediated by cortisol, was most effective during open-access conditions, and did not prevent or reduce relapse drinking.

Given the significant cost of alcohol use disorder (AUD), identifying risk factors for alcohol seeking represents a research priority. Prominent addiction theories emphasize the role of motivation in the alcohol seeking process, which has largely been studied using preclinical models. In order to bridge the gap between preclinical and clinical studies, this study examined predictors of motivation for alcohol self-administration using a novel paradigm. Heavy drinkers (n = 67) completed an alcohol infusion consisting of an alcohol challenge (target breath alcohol = 60 mg%) and a progressive-ratio alcohol self-administration paradigm (maximum breath alcohol 120 mg%; ratio requirements range = 20-3 139 response). Growth curve modeling was used to predict breath alcohol trajectories during alcohol self-administration. K-means clustering was used to identify motivated (n = 41) and unmotivated (n = 26) self-administration trajectories. The data were analyzed using two approaches: a theory-driven test of a-priori predictors and a data-driven, machine learning model. In both approaches, steeper delay discounting, indicating a preference for smaller, sooner rewards, predicted motivated alcohol seeking. The data-driven approach further identified phasic alcohol craving as a predictor of motivated alcohol self-administration. Additional application of this model to AUD translational science and treatment development appear warranted.

Introduction: Alcohol craving is a key symptom of alcohol use disorder (AUD) and a significant cause of poor treatment outcome and frequent relapse. Craving is supposed to impair executive functions by modulating reward salience and decision-making. Objective: The present study sought to clarify this modulation by scrutinizing reward feedback processing in an experimental decision-making task, which was accomplished by AUD patients in 2 conditions, in the context of induced alcohol craving and in neutral context. Methods: AUD inpatients (N = 40) accomplished the Balloon Analog Risk Task, while their EEG was monitored; counterbalanced across conditions, the tasks were preceded either by craving induction by means of imagery and olfactory alcohol cues, or by neutral cues. Decision choice and variability, and event-related potentials (ERPs) prior to (stimulus-preceding negativity [SPN]) and following (P2a) reward feedback upon decisions, and the outcome-related feedback-related negativity (FRN) were compared between conditions and between patients, who experienced high craving upon alcohol cues (N = 18) and those who did not (N = 22). Results: Upon craving induction (vs. neutral condition), high-craving AUD patients showed less adjustment of decision choice to preceding reward experience and more variable decisions than low-craving AUD patients, together with accentuated reward-associated ERP (SPN and P2a), while outcome-related FRN was not modified by craving. Conclusions: Results support orientation to reward in AUD patients, particularly amplified upon experienced craving, which may interfere with (feedback-guided) decision-making even in alcohol-unrelated context. Craving-accentuated ERP indices suggest neuroadaptive changes of cognitive-motivational states upon chronic alcohol abuse. Together with altered reward-related expectancies, this has to be considered in intervention and relapse prevention.

Background Multiple measures are utilized to assess alcohol craving, often interchangeably. Little is known about the relationship between tonic and phasic craving. This study fills this gap in the literature by examining the association between tonic levels of alcohol craving and phasic craving for alcohol that is provoked by alcohol administration. Methods Forty-three non-treatment seeking problem drinkers underwent an initial interview and two laboratory testing sessions, where either alcohol or a saline placebo was administered intravenously. Tonic craving was assessed via the Penn Alcohol Craving Scale (PACS) and Obsessive Compulsive Drinking Scale (OCDS) at the initial interview. Phasic craving was assessed during the laboratory sessions (i.e., alcohol and saline administrations, single blinded) at baseline and at 3 subsequent breath alcohol concentrations (0.02, 0.04, and 0.06 g/dl). Results There was a main effect of PACS in predicting phasic craving across both saline and alcohol administration conditions (p 0.10), predicted phasic craving during alcohol, as compared to saline administration. Conclusion In sum, tonic craving captured by the OCDS was predictive of phasic craving during alcohol administration whereas the PACS more generally captured the increase in phasic craving. Therefore, these measures of tonic craving may function differently in capturing the experience of phasic craving. Implications for the utilization of the PACS and OCDS as well as assessments of craving in alcoholism research are discussed., Highlights • Many measures are utilized, often interchangeably, to assess alcohol craving. • Little is known about the relationship between provoked, phasic craving and long-term, tonic craving. • Results indicated that the PACS predicted phasic craving, regardless of alcohol condition. • The OCDS predicted phasic craving when alcohol was administered.

Introduction A preliminary study showed the existence of a relationship between alcohol craving and insomnia symptoms. The current investigation aimed to further assess the relationship between obsessive and compulsive qualities of alcohol craving and insomnia disorder in a larger sample of subjects with Alcohol Use Disorder (AUD) seeking treatment for their drinking. Methods We used baseline cross-sectional data from a clinical trial of treatment-seeking patients with AUD (N=123). We used the following instruments: Insomnia Severity Index (ISI) total score for insomnia; Obsessive Compulsive Drinking Scale (OCDS) scale scores for alcohol craving; Time-Line follow Back interview for computing the number of drinks per drinking day within the past 90 days; Hamilton Anxiety Rating Scale total score for the anxiety symptoms; and Addiction Severity Index for demographic variables. We used bivariate analysis to evaluate whether alcohol craving outcome measures (OCDS subscale scores and total score) were independently associated with the ISI total score. A multivariable model adjusted for sociodemographic and clinical covariates further evaluated this relationship between OCDS and ISI total scores. Results The mean (SD) age was 44.02 (10.37) years with 13.29 (3.10) years of education, 83.74% were males, 41.80% identified themselves as White, 17.21% were married, and 56.09% were employed. In a bivariate analysis, ISI total score was associated with the obsessive subscale (β=0.25, p Conclusion This study not only confirmed that alcohol craving was associated with insomnia in a larger sample but also demonstrated that insomnia is linked to both obsessive thoughts about alcohol use and compulsive drinking behavior, especially its obsessive aspect. These findings add to the growing literature on the relationship between a pathologic drive for alcohol use and abnormal wakefulness. Support (if any) The study was supported by VA grant IK2CX000855 (S.C.) and NIH grants R01 AA016553 (K.M.K.).

Greater knowledge is needed of potential predictive factors for suicide in cases of alcohol addiction. Therefore, the aim of the study was to identify the socio-demographic variables and clinical factors associated with alcohol dependence which may have an influence on the occurrence of suicidal thoughts in alcohol-dependent patients. A group of 510 patients (396 male and 114 female) diagnosed with alcohol dependence syndrome were interviewed during the third week of therapy according to the Beck Depression Inventory (BDI), the Penn Alcohol Craving Scale (PACS) and the Short Alcohol Dependence Data Questionnaire (SADD). Socio-demographic data was also collected. The results of a binary logistic regression with suicidal thoughts as a dependent variable show that 63 out of the 510 participants (12% of the sample) reported the presence of suicidal thoughts. Alcohol dependence and alcohol craving appear to increase the likelihood of suicidal thoughts, and participants presenting psychiatric disorders were twice as likely to demonstrate suicidal ideation as those who did not. Alcohol dependence, alcohol craving and psychiatric comorbidity may be regarded as risk factors for suicidal ideation in the studied sample, with the only protective factor being living in a relationship.

Aims DSM-5 has added craving as a new criterion and changed the diagnostic structure of alcohol use disorder (AUD). Though craving has long been a target of intervention, less is known about the impact this addition will have on prevalence and factor structure of AUD, particularly in non-treatment seeker with alcohol problems. Methods Non-treatment seeking individuals reporting alcohol-related problems (N = 296) completed a structured clinical interview and the Penn Alcohol Craving Scale (PACS). PACS scores greater than 20 were considered to meet diagnostic criteria for the alcohol craving symptom. This study examined DSM-IV to DSM-5 diagnostic conversion and conducted an exploratory factor analysis to test the factor structure of the DSM-5 symptoms, including craving. Results The mean PACS score was 13.1 and alcohol craving was strongly correlated with other measures of alcohol use. Using the proposed cut-off score of PACS > 20, 46 participants (16.2%) met criteria for alcohol craving. Craving loaded moderately (0.47) onto the retained DSM symptoms and produced a unidimensional factor structure. The majority of participants who met for a DSM-IV AUD also met for a DSM-5 AUD (98.8%). Conclusions Craving prevalence using the PACS was relatively low compared to the remaining 10 DSM-5 symptoms, possibly due to the non-treatment seeking nature of the sample. Conversion of DSM-IV to DSM-5 in this sample led to a small increase in overall AUD prevalence. Craving loaded well onto a single factor structure for AUD.

Corticotropin releasing factor (CRF) is a neuropeptide that plays a key role in behavioral and physiological responses to stress. A large body of animal literature implicates CRF acting at type 1 CRF receptors (CRFR1) in consumption by alcohol dependent subjects, stress-induced reinstatement of alcohol seeking, and possibly binge alcohol consumption. These studies have encouraged recent pilot studies of CRFR1 antagonists in humans with alcohol use disorder (AUD). It was a great disappointment to many in the field that these studies failed to show an effect of these compounds on stress-induced alcohol craving. Here, we examine these studies to explore potential limitations, and discuss preclinical and human literature to ask whether CRFR1 is still a valid drug target to pursue for the treatment of alcohol use disorder.

Women are particularly likely to drink alcohol for the purpose of coping with or alleviating negative affect. Engaging in physical activity has been posited as a potentially effective alternate coping strategy during early recovery for managing mood and cravings. Utilizing exercise to cope may be associated with more adaptive coping strategies in general. Additionally, an intrinsic (autonomous) motivational style and positive beliefs about exercise are associated with long-term adherence to physical activity. The current study evaluates changes in coping strategies, autonomous motivation, and beliefs about exercise among women engaged in a physical activity intervention during early recovery (N=20; mean age=39.53). General coping strategies, motivational style, and beliefs about exercise were examined before and after engaging in the 12-week intervention which aimed to help women utilize physical activity as a means to cope with negative affect and alcohol craving. We found that, by the end of the intervention, participants significantly increased utilization of adaptive coping strategies such as the use of emotional support from others. Additionally, participants increased autonomous motivation over time. There were no significant changes in beliefs about exercise. Changes in beliefs about benefits of exercise, autonomous motivation, and adaptive coping were related to use of exercise to cope. However, even though these changes were associated with how women in the intervention used exercise, they were not associated with exercising more. Results from this open pilot suggest that women in early recovery from alcohol who increase physical activity - specifically as a means to cope with negative affect and craving - also demonstrate other wider coping strategies, more positive beliefs, and autonomous motivation.

Women in alcohol treatment are more likely to relapse when in unpleasant, negative emotional states. Given the demonstrated benefits of exercise for decreasing depression, negative affect, and urges to drink, helping women engage in a lifestyle physical activity (LPA) intervention in early recovery may provide them a tool they can utilize "in the moment" in order to cope with negative emotional states and alcohol craving when relapse risk is highest. New digital fitness technologies (e.g., Fitbit activity monitor with web and mobile applications) may facilitate increases in physical activity (PA) through goal setting and self-monitoring.We piloted a 12-week LPA+Fitbit intervention focused on strategically using bouts of PA to cope with affect and alcohol cravings to prevent relapse in 20 depressed women (mean age=39.5years) in alcohol treatment.Participants wore their Fitbit on 73% of days during the intervention period. An average of 9174 steps/day were taken on the days the Fitbit was worn. Participants completed 4.7 of the 6 scheduled phone PA counseling sessions (78%). Among women who completed the intervention (n=15), 44% remained abstinent throughout the entire course of treatment. On average, women were abstinent on 95% of days during the 12-week intervention. Participants reported an increase in using PA to cope with either negative affect or urges to drink from baseline to end of treatment (p0.05). Further, participants reported high satisfaction with the LPA+Fitbit intervention and with the Fitbit tracker.Further research is needed to evaluate the LPA+Fitbit intervention in a more rigorous randomized controlled trial. If the LPA+Fitbit intervention proves to be helpful during early recovery, this simple, low-cost and easily transported intervention can provide a much-needed alternate coping strategy to help reduce relapse risk among women in alcohol treatment.

Rash impulsiveness, the propensity for approach behaviour despite potential negative consequences, is associated with stronger alcohol craving in patients with Alcohol Use Disorder (AUD). This relationship is poorly understood and implications for treatment response are unexamined. This study explored the relationship between rash impulsiveness, craving, and treatment response among 304 outpatients enrolled in a 12-week abstinence-based Cognitive-Behavioural Therapy (CBT) program for AUD. Assessments were completed pre-and-post treatment, with craving and alcohol consumption monitored at each treatment session. Higher rash impulsiveness predicted more frequent craving over treatment (b = 0.95, 95% CI = 0.40, 1.50). Higher craving was associated with greater lapse-risk (b = 0.04, 95% CI = 0.03, 0.05), with the association between craving and lapse-risk increasing as treatment progressed (b = 0.01, 95% CI = 0.01, 0.02). Craving positively mediated the relationship between rash impulsiveness and lapse-risk (µ = 0.38, 95% CI = 0.10, 0.70). Contrary to hypotheses, the risk of lapse in response to craving was not moderated by rash-impulsiveness. These results suggest that AUD patients with a predisposition for rash impulsiveness are more vulnerable to alcohol craving, and subsequently, poorer treatment outcomes.

Craving for alcohol or the strong desire or urge to consume it, is a diagnostic marker of alcohol use disorder. Within clinical settings, appropriate craving assessment can inform diagnosis, prognosis, treatment, and evaluation of treatment outcome. A number of craving instruments are available which complicates measure selection. Important considerations in measure selection include: the measure’s definition and theoretical foundation of craving, psychometric integrity, administration demands, temporal reference, and clinical utility. This chapter reviews these aspects as they relate to the Alcohol Craving Experience Questionnaire.

Background: Alexithymia is a personality trait associated with emotion regulation difficulties. Up to 67% of alcohol-dependent patients in treatment have alexithymia. Objectives: The objective of this study was to investigate the direct and indirect effects of alexithymia, negative mood (stress, anxiety, and depression) and alcohol craving on alcohol dependence severity. Methods: Three hundred and fifty-five outpatients (mean age = 38.70, SD = 11.00, 244 males, range 18-71 years) undergoing Cognitive-Behavioral Therapy for alcohol dependence completed the Toronto Alexithymia Scale (TAS-20), Depression Anxiety Stress Scales (DASS-21), Obsessive Compulsive Drinking Scale (OCDS), and Alcohol Use Disorders Identification Test (AUDIT) prior to the first treatment session. Results: Alexithymia had an indirect effect on alcohol dependence severity, via both negative mood and alcohol craving (b = 0.03, seb = 0.008, 95% CI: 0.02-0.05). An indirect effect of negative mood on alcohol dependence via alcohol craving was also observed (b = 0.12, seb = 0.03, 95% CI: 0.07-0.16). Conclusions/importance: Alexithymia worked through negative mood and alcohol craving leading to increased alcohol dependence severity, indicating that craving had an indirect effect on the relationship between alexithymia and alcohol dependence severity. Targeting alcohol craving and negative mood for alcohol-dependent patients with alexithymia seems warranted.

This research presents the development of the algorithm that predict excessive alcohol consumption by using sensors on smartphones in order to solve problems of alcohol drinkers who is unaware of their own alcohol consumption level. Since this incident results in several problems such as, road accidents. Therefore, this algorithm was developed to replace Breathalyzer, which most people do not have. This algorithm will use data from the sensors on smartphones, which most people already have in possession, to forecast alcohol over dosage. The experiment conducted from 6 people of 23 sample groups, which is 100% accurate, revealed that this algorithm could be used instead of the Breathalyzer in a certain extent.

The previous scenario is based on a first-person recollection of attending a party that was developed into a virtual reality scenario by Dr. Bordnick at the Virtual Reality Clinical Research Lab. This scenario was used to construct a virtual reality platform to assess and eventually decrease alcohol craving, offering a novel approach to substance abuse treatment.

Background: Craving plays an important role in maintenance of alcohol dependence. Earlier studies have analyzed the role of ghrelin in craving and their results have been heterogenous. Acyl ghrelin is its more active form as it crosses the blood brain barrier. Hence we aimed to examine the relationship between plasma acyl ghrelin and craving in Indian patients having alcohol dependence syndrome. Methods: The present study was a hospital-based prospective study. A total of 60 drug-naive patients of alcohol dependence and 30 healthy controls were included. After taking informed consent fasting blood samples were collected from them on day 1 and tested for plasma acyl ghrelin level. Fasting blood samples were repeated in all cases on day 14. During this time, we also assessed the patients' cravings by obsessive compulsive drinking scale, and alcohol craving questionnaire; and withdrawal by clinical institute withdrawal assessment for alcohol scale. These scales were repeated on day 14. Data analysis was done by SPSS version 25.0. Results: Plasma concentrations of acyl ghrelin increased significantly during early abstinence in patients from day 1 to day 14 (P < 0.0001). Pearson correlation test revealed a trend of positive correlation between plasma concentration of acyl ghrelin on day 14 and severity of craving on day 1. Conclusion: Our results suggest the plasma concentration of acyl ghrelin may be a predictor of severity of alcohol craving during early abstinence. Anti-craving drugs acting on acyl ghrelin level in brain may open an innovative avenue for optimum treatment of alcohol dependence.

Background Chronic pain and alcohol use disorder (AUD) are often co-occurring conditions. Pain catastrophizing, an emotional component of pain, and pain intensity are related to alcohol use as a coping mechanism; however, how pain interacts with tonic alcohol craving is an understudied area. This study sought to determine the unique and independent effects of pain intensity and pain catastrophizing on alcohol craving in heavy drinkers. Method Non-treatment seeking heavy drinkers (n = 128) completed self-report measures of pain (both intensity and catastrophizing), depression, alcohol use and problems, and reasons for heavy drinking. A hierarchical regression examined the unique contribution of pain intensity to alcohol craving. Depression, pain catastrophizing, and alcohol use measures were added to the hierarchical model in sequential blocks. Results The final model of the hierarchical regression demonstrated that pain catastrophizing has an independent effect on alcohol craving over and above demographic, pain intensity, depression, and alcohol measures. Exploratory analyses suggest that individuals in the high intensity pain grade have higher levels of depression symptomology, pain catastrophizing, alcohol use and problems, as well as engaging in heavy drinking to “feel normal” compared to the no pain and low intensity pain grades. Conclusions These results demonstrate that pain catastrophizing predicts alcohol craving independent of self-reported chronic pain intensity. Individuals with high intensity chronic pain have more severe alcohol use and mood-related symptomology. Upon replication in clinical samples, these findings can inform clinical care for pain management.
