  • Evaluative conditioning: A brief computer-delivered intervention to reduce
           college student drinking

      Background Recent research suggests that a brief computer-delivered intervention based on evaluative conditioning (EC) can change the implicit evaluation of alcohol and reduce drinking behaviors among college students. We tested whether we could obtain similar findings in a high-powered preregistered study and whether hazardous drinking moderates these effects. Method Before the intervention, 122 French college students were screened for hazardous drinking using the Alcohol Use Disorder Identification Test (AUDIT). Implicit evaluation of alcohol was assessed before and immediately after the intervention using an Implicit Association Test (IAT). Drinking behavior was assessed before the intervention and approximately two weeks after using the TimeLine Follow Back (TLFB) method. The EC consisted of 120 trials of words (related to alcoholic beverages, soft drinks or neutral) paired with pictures (neutral, positive or negative). In the EC condition, alcohol-related words were systematically paired with negative pictures. In the control condition, alcohol-related words were systematically paired with neutral pictures. Results The EC did not change the implicit evaluation of alcohol, Cohen's d = 0.01, 95CI [−0.35, 0.35]. However, the EC reduced drinking behavior, Cohen's d = 0.37, 95CI [0.01, 0.72]. This effect was independent of hazardous drinking behavior, but it was especially pronounced among participants with the most positive implicit evaluation of alcohol before the intervention. Conclusion This preregistered study suggests that evaluative conditioning can successfully reduce drinking behavior among college students by 31% (compared to 4% in the control condition) without causing an immediate change in the implicit evaluation of alcohol.

  • Parental smoking, rejection of parental smoking, and smoking
           susceptibility and behaviors in Hong Kong adolescents

      Introduction We explored the role of rejection of parental smoking in the association between parental smoking and smoking in adolescents. Methods In 2010–11 cross-sectional survey, 61,810 Hong Kong secondary school students (mean age 14.6 years, 50.5% boys) reported their smoking (never, not susceptible; never, susceptible; ever, not current; current), paternal and maternal smoking, and whether they accepted paternal and maternal smoking (acceptance/rejection). We used multinomial logistic regression to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of students' smoking in relation to acceptance and rejection of parental smoking, compared with no parental smoking. Results The OR (95% CI) of “never, susceptible”, “ever, not current”, and “current”, compared with “never, not susceptible”, in relation to acceptance of paternal smoking was 1.81 (1.67–1.96), 2.46 (2.25–2.69), and 2.79 (2.51–3.10), respectively. The corresponding ORs for rejection were 0.70 (0.64–0.76), 1.23 (1.13–1.35), and 0.47 (0.40–0.56). The OR (95% CI) of “never, susceptible”, “ever, not current”, and “current”, compared with “never, not susceptible”, in relation to acceptance of maternal smoking was 2.05 (1.80–2.33), 2.57 (2.29–2.88), and 6.33 (5.39–7.44), respectively. The corresponding ORs for rejection were 0.85 (0.69–1.05), 1.59 (1.39–1.81), and 2.14 (1.71–2.68). No overlapping was observed between the 95% CIs for acceptance and rejection of paternal or maternal smoking. Conclusions While adolescent smoking was associated with parental smoking, especially in those who accepted parental smoking, the association was attenuated or reversed in those who rejected parental smoking.

      Introduction The purpose of this study was to investigate individual engagement and comfort during a web-based intervention for alcohol and sexual assault risk reduction. Methods Participants were 264 college women (aged 18–20) who reported engaging in heavy episodic drinking in the past month. Participants were randomized to either an intervention condition (alcohol, sexual assault risk reduction, or combined) or a control condition (full or minimal assessment). Participants rated their experiences during the procedures following the assessment or receipt of the intervention depending on condition. Survey usage information (e.g., time data, completion of intervention) was automatically recorded. Results Most participants completed the intervention as intended (in a reasonable amount of time, in private, without consuming substances). Women with a sexual assault history were most comfortable in the sexual assault risk reduction intervention, whereas women who frequently engaged in heavy episodic drinking were least comfortable in the alcohol intervention condition. Self-reported distraction was not impacted by personal relevance of the intervention, but was associated with setting of participation. Conclusions Results suggest that most college women completed web-based personalized feedback interventions as designed, despite minimal discomfort.

      Introduction Peer crowds, peer groups with macro-level connections and shared norms that transcend geography and race/ethnicity, have been linked to risky health behaviors. Research has demonstrated that Hip Hop peer crowd identification, which is common among multicultural youth, is associated with increased risk of tobacco use. To address this, the FDA Center for Tobacco Products created Fresh Empire, the first national tobacco education campaign tailored for Hip Hop youth aged 12–17 who are multicultural (Hispanic, African American, Asian-Pacific Islander, or Multiracial). As part of campaign development, peer crowd (Hip Hop, Mainstream, Popular, Alternative, Country) and cigarette smoking status were examined for the first time with a nationally recruited sample. Methods Youth were recruited via targeted social media advertisements. Participants aged 13–17 (n = 5153) self-reported peer crowd identification via the I-Base Survey™ and cigarette smoking status. Differences in smoking status by peer crowd were examined using chi-square and followed up with z-tests to identify specific differences. Results Alternative youth were most at risk of cigarette smoking, followed by Hip Hop. Specifically, Hip Hop youth were significantly less likely to be Non-susceptible Non-triers than Popular, Mainstream, and Country youth, and more likely to be Experimenters than Popular and Mainstream youth. Conclusions Representative studies show that Alternative is relatively small compared to other high-risk crowds, such as the Hip Hop peer crowd. The current research underscores the potential utility of interventions tailored to larger at-risk crowds for campaigns like Fresh Empire.

      Introduction Despite previous evidence supporting the use of the Cigarette Purchase Task (CPT) as a valid tool for assessing smoking reinforcement, research assessing how environmental changes affect CPT performance is scarce. Aims This study addressed for the first time the differential effect of treatment condition [Cognitive Behavioral Treatment (CBT) + Behavioral Activation (BA) versus CBT + BA + Contingency Management (CM)] on cigarette demand among treatment seeking smokers with depressive symptoms. It also sought to assess whether reductions in smoking consumption arranged over the course of an intervention for smoking cessation impact on in-treatment cigarette demand. Method Participants were 92 smokers with depressive symptoms from a randomized clinical trial that received eight weeks of either CBT + BA or CBT + BA + CM. Individuals completed the CPT 8 times; the first during the intake visit and the remaining 7 scheduled once a week in midweek sessions. Cotinine samples were collected in each session. Results Participants receiving CBT + BA + CM showed higher reduction in cigarette demand across sessions than participants receiving CBT + BA, although this comparison was only significant for the intensity index (p = .004). Cotinine was positively related to cigarette demand (all p values < .001), although this association became less prominent across sessions. In-treatment cotinine decreases were associated with demand reductions (all p values < .001), but this association was not significant for elasticity. Conclusions Reductions in nicotine intake arranged over the course of an intervention for smoking cessation impact in-treatment cigarette demand.

      Mindfulness-based interventions (MBI) are increasingly used in the treatment of patients with mental disorders, in particular in individuals presenting with affective disorders or in patients exhibiting abnormal levels of impulsive behavior. MBI have been also offered to patients with substance use disorders, where such treatment options may yield considerable clinical effects. Neural effects associated with MBI have been increasingly acknowledged, but is unknown whether MBI exert specific effects on brain structure in patients with substance use disorders. In this study, we investigated 19 inpatients with opioid dependence receiving treatment-as-usual (TAU, n = 9) or additional MBI (n = 10). Structural magnetic resonance imaging data were acquired before and after four weeks of treatment. Source-based morphometry was used to investigate modulation of structural networks after treatment. Both treatment modalities led to significant clinical improvement. Patients receiving MBI showed a significant change in distress tolerance levels. An increase in bilateral striatal/insular and prefrontal/cingulate network strength was found in patients receiving MBI compared to individuals receiving TAU. Prefrontal/cingulate cortical network strength was associated with impulsivity levels. These findings suggest that MBI can have a recognizable role in treatment of substance use disorders and that neural effects of MBI may be captured in terms of frontostriatal structural network change.

      Background Alcohol use and misuse have been intensively studied, due to their negative consequences in the general population. Evidence-based literature emphasizes that alcohol craving plays a crucial role in the development and maintenance of alcohol-drinking patterns. Many individuals develop Alcohol Use Disorders (AUD); significantly, after treatment many also experience relapses, in which alcohol craving has been repeatedly implicated. Cue-exposure therapy (CET) has been widely used in the treatment of alcohol misuse, but the results are inconsistent. Virtual reality (VR) can add effectiveness to cue-exposure techniques by providing multiple variables and inputs that enable personalized alcohol use assessment and treatment. The aim of this review was to examine the applications of virtual reality in individuals who misuse alcohol. Method We conducted an exhaustive literature search of the Web of Science, Scopus, Embase, Google Scholar, and PsycInfo databases, using as search items terms such as “alcohol” and its derivates, and virtual reality. Results We identified 13 studies on alcohol craving that implemented virtual reality as an assessment or treatment tool. Conclusions The studies that incorporate VR present clear limitations. First, no clinical trials were conducted to explore the efficacy of the VR as a treatment tool; nor were there any studies of the generalization of craving responses in the real world, or of the long-term effects of VR treatment. Despite these limitations, the studies included showed consistent results as regards eliciting and reducing alcohol craving. We suggest that VR shows promise as a tool for the assessment and treatment of craving among individuals with alcohol misuse. Further studies implementing VR in the field of alcohol consumption are now required.

      Aims In seeking to provide more accurate models of population quit attempt rates, this study assessed whether a single self-report measure of consistent motivation to stop smoking adds useful explanatory power over and above an established measure of current motivation to stop. Method Data from 16,657 current smokers in England were collected between October 2012 and June 2017 using cross-sectional household surveys. Smokers were asked whether they had made a serious quit attempt in the past year and they answered two questions on motivation to stop (current motivation and consistent motivation to stop smoking). Having made at least one quit attempt in the past year was regressed in logistic models onto current motivation to stop and consistent motivation to stop individually and then together, with both models adjusting for sociodemographic variables and a measure of nicotine dependence. Results The addition of consistent motivation to stop smoking added substantially to the fit of the model over and above the established measure of current motivation to quit (χ2(1, N = 16,657) = 901.7, p < 0.001) with an adjusted odds ratio of 4.1 (95% CI = 3.7–4.5, p < 0.001). Conclusion Consistent motivation to stop smoking substantially improves the modelling of recent smoking cessation attempts over and above current motivation to stop. The consistency of smokers' motivation to quit may be a useful explanatory and target variable in future intervention studies.

      Introduction A significant proportion of chronic cannabis users experience occupational, social, and psychological problems thought to reflect, in part, cannabis-related cognitive and emotional attentional biases. The emotional attentional blink (EAB) is a unique test of attentional bias that assesses automatic responses, cue-detection failures, and rapid and temporally extended biases. Using the EAB, we tested users' and non-users' attentional biases and how cannabis exposure correlates with these attentional biases. Methods Forty-eight regular cannabis users and 51 non-users completed demographic, psychological, and cannabis-use reports and two EAB target-detection experiments. Each experiment comprised 160 trials. Each trial included a rapid serial visual presentation of images with one of four types of distractor images (cannabis, generically positive, neutral, or scrambled) preceding the target image. Distractor images were presented 200ms (Lag 2) or 800ms (Lag 8) before the target in Experiment 1 and 200ms (Lag 2) or 500ms (Lag 5) before the target in Experiment 2. Results Chronic cannabis users exhibited exaggerated, immediate attentional bias (Lag 2) and exaggerated, extended attentional bias (Lag 5) compared to non-users. The intensity of cannabis-use (grams per week) correlated with more errors at the extended attentional bias durations (Lags 5 and 8). Conclusions Our results represent novel evidence of automatic attentional capture consistent with an exaggerated “wanting” motive in models of addiction. Our unique evidence of temporally extended attentional biases is consistent with attentional disengagement deficits associated with chronic cannabis use.

      Introduction Concurrent use of cigarettes with alternative tobacco products (ATPs), even among very light smokers, may be harmful. This study examined current use of e-cigarettes, cigars, and hookah, and susceptibility to future use of these products in a sample of college student cigarette smokers. Methods Participants were 1161 18–29 year old (M age = 21.15; SD = 2.72; 52.7% female; 41.2% non-Hispanic white) current, or past 30-day cigarette smokers, drawn from a larger study. Current smokers were categorized as very light smokers [≤5 cigarettes per day (cpd)] and heavier smokers (>5 cpd). Results 88.6% of all participating college student smokers were very light smokers and 67.7% used at least one ATP concurrently. The prevalence of current use in this sample was 42.9% for e-cigarettes, 36.4% for hookah, and 25.9% for cigars. Compared to heavier smokers, very light smokers were more likely to be younger, racial/ethnic minorities, and four-year versus two-year college students. Multilevel logistic regression models showed that after controlling for socio-demographic characteristics and substance use, being a very light smoker, compared with a heavier smoker, was negatively associated with concurrent e-cigarette use, but positively associated with concurrent cigar use, and not associated with concurrent hookah use. Moreover, compared to heavier smokers, very light smokers reported being more susceptible to future cigar and hookah use, but not e-cigarette use. Conclusions Concurrent use of cigarettes with ATPs is popular among all college student smokers, but very light smokers are more likely than heavier smokers to use combustible ATPs. Smoking intervention programs and campus policies should caution smokers, especially very light smokers, against ATP use.

      The emerging retail market for recreational marijuana use warrants research and surveillance as such markets are established in more US states. This research can be informed by the existing literature regarding tobacco and alcohol, which highlights the impact of spatial access to tobacco and alcohol retailers and exposure to tobacco and alcohol marketing on smoking and drinking among youth and young adults. Prior research indicates that tobacco and alcohol retailers, as well as medical marijuana dispensaries, are disproportionately located in neighborhoods characterized by socioeconomic disadvantage and by higher proportions of racial/ethnic minorities and young adults. Moreover, retail marketing or point-of-sale practices may differentially target subpopulations and differ by neighborhood demography and local policy. This literature and the methods employed for studying the tobacco and alcohol market could inform research on the retail environment for marijuana, as current gaps exist. In particular, much of the existing literature involves cross-sectional research designs; longitudinal studies are needed. Moreover, standardized measures are needed for systematic monitoring of industry marketing practices and to conduct research examining neighborhood differences in exposure to retail marketing for marijuana and its contribution to use modality and frequency, alone and in combination with nicotine and alcohol. The use of standardized measures for tobacco and alcohol marketing have been critical to develop an evidence base from cross-sectional and longitudinal studies that document the impact of retail marketing on substance use by adolescents and adults. Similar research is needed to establish an evidence base to inform federal, state, and local regulations of marijuana.

      Several studies have suggested that Internet gaming disorder (IGD) is related to altered brain white matter integrity. However, seeming inconsistencies exist and may reflect comparison groups not matched well for certain gaming characteristics. In order to address this possible concern, we recruited in the present study individuals with recreational Internet game use (RGU) comprised of individuals who spend similar amounts of time as IGD subjects playing online games without developing IGD. Diffusion tensor imaging data were collected from 42 IGD and 44 RGU subjects. Whole-brain comparisons showed that IGD subjects demonstrated increased fractional anisotropy (FA) in the bilateral anterior thalamic radiation, anterior limb of the internal capsule, bilateral corticospinal tract, bilateral inferior fronto-occipital fasciculus, corpus callosum, and bilateral inferior longitudinal fasciculus. In addition, Internet-addiction severity was positively correlated with FA values. Taken together, we conclude that IGD is associated with measures of increased white-matter integrity in tracts linking reward circuitry and sensory and motor control systems.

      Heavy episodic drinking (4+/5+ drinks/occasion for females/males) is highly prevalent among college students and is influenced by social factors. Among these social risk factors, perceived peer drinking norms have been shown to significantly predict heavy episodic drinking across a number of studies. However, there is little known about which students may be most and least susceptible to these influences or why individual differences may moderate the impact of norms on heavy drinking. Recent work has suggested self-control may be an important individual difference factor in this regard. Working memory (WM) is a central component of self-control that has been shown to buffer the effect of social influence variables. This study examined whether WM, as measured by memory span tasks, moderates the relationship between perceived drinking norms and alcohol use among college students reporting one or more past month drinking occasions (n = 98). Hierarchical linear regression analyses were used to examine whether WM significantly moderated the relationship between perceived norms and heavy drinking episodes (HDEs) as well as number of drinking days in the past month. Analyses revealed a significant WM x norms interaction for both drinking indices. Simple slopes analyses suggested a buffering effect of WM as higher perceived norms predicted more HDEs and drinking days at low (−1SD) and mean WM scores but not high (+1SD) WM. These results suggest WM serves as a protective factor for the influence of norms such that individuals high in WM may be more able to inhibit the impact of norms on alcohol use.

      Cannabis users tend to use condoms less often than cannabis abstainers, placing them at risk for sexually transmitted disease and unplanned pregnancies. This is especially problematic among college students, who experience such problems at especially high rates. Despite accumulating data indicating that cannabis users are less likely to use condoms, little research has identified potentially malleable cognitive vulnerability factors that may be related to condom use in this vulnerable population. Thus, the current study tested whether cannabis users believed others use condoms less often and/or whether they engaged in less condom-related protective behavior strategies (PBS) than cannabis abstainers and whether cannabis use status was indirectly related to condom use via these vulnerability factors. Among 214 college students (64 past-month cannabis users), cannabis users engaged in less PBS (although cannabis use was unrelated to normative beliefs). Cannabis use status was indirectly related to condom use via PBS and cannabis use status was unrelated to condom use after controlling for PBS. Results highlight the importance of PBS use among cannabis users, a group at particular risk for risky sexual behaviors.

      Historically, research has demonstrated that multiple substance use, compared to single substance use, poses additional challenges for treatment throughout the continuum of care including referrals, interventions, and relapse prevention. However, it appears that this pattern cannot be easily generalized to all criminal justice settings as evidenced by mixed findings across criminal justice samples. The purpose of the current study is to investigate possible differences in legal and substance-related outcomes between multiple substance users and single substance users within a community corrections sample. Structured clinical interviews were conducted to divide 531 individuals under community corrections supervision into three groups including multiple substance users, single substance users, and non-substance users. Results indicated that while multiple substance users were arrested more frequently and had more problems with family members, there were no differences compared to their single substance using counterparts in terms of depressive disorders, anxiety disorders, or types of offense. These findings contrast with previous research on samples outside of community corrections suggesting that multiple substance use requires tailored interventions with consideration to context of their use. Discussion includes limitations to generalizability and assessment of substance use as well as implications for treatment and future research.

      Despite of high rates of adverse childhood experiences (ACEs) in pathological gamblers, researchers have rarely studied which types of ACEs often co-occur and how these profiles of ACEs are related to current psychopathology. We aimed to identify profiles of ACEs in pathological gamblers and examined how these profiles were related to gambling-related characteristics and current general psychopathology. In 329 current or lifetime pathological gamblers, diagnosed with the Composite Diagnostic Interview for DSM-IV, 10 types of ACEs were measured using the Adverse Childhood Experiences Questionnaire. Global psychopathology was assessed using the Symptom Checklist SCL-27. ACE profiles were identified using latent class analysis. Differences between ACE profiles in gambling-related characteristics and global psychopathology were analyzed using MANOVA. We found that four out of five gamblers (n =257, 78.1%) reported at least one ACE. Four distinct ACE profiles were identified: ‘Low ACE’, ‘High ACE’, ‘Physical and emotional abuse’, and ‘Neglect’. The number of the fulfilled pathological gambling criteria and the severity of current global psychopathology differed between the ACE profiles: Gamblers with a ‘High ACE’ profile fulfilled more pathological gambling criteria and showed a more severe current psychopathology than gamblers of the ‘Low ACE’ profile. Gamblers with a ‘Physical and emotional abuse’ or an ‘Emotion neglect’ profile showed an intermediate severity of psychopathology. Our findings indicate that four different ACE profiles can be distinguished in pathological gamblers that differed in their gambling-related characteristics and current psychopathology. Systematic assessment of profiles of ACEs in pathological gamblers may inform about the severity of current global psychopathology that might be important to be addressed in addition to gambling-specific treatment.

      Background This study aimed to develop and validate a shortened version of the Drinking Refusal Self-Efficacy Questionnaire-Revised Adolescent version (DRSEQ-RA) using a large sample of adolescents. Methods Secondary school students (N = 2609, M = 14.52 years, SD = 0.94) completed the DRSEQ-RA (consisting of subscales: Social Pressure; Opportunistic; Emotional Relief) and the Alcohol Use Disorders Identification Test (AUDIT). These data were analysed using non-parametric item response theory (NIRT) including Mokken scalability coefficients, and confirmatory factor analysis. Results Social Pressure subscale items were better able to distinguish between adolescents with lower or higher levels of drinking refusal self-efficacy, while the Opportunistic and Emotional Relief subscale items were able to distinguish adolescents with low drinking-refusal self-efficacy. The DRSEQ-RA was reduced from 19-items to a 9-item scale and retained the original three-factor structure. The reduced scale was named the Drinking Refusal Self-Efficacy Questionnaire-Shortened Revised Adolescent version (DRSEQ-SRA). The DRSEQ-RA and the DRSEQ-SRA have almost identical psychometric properties. They both demonstrated good fit to the data, each explained 18% of the variance in alcohol consumption, Adj. R 2 = 0.18, p < .001 respectively. The DRSEQ-RA and the DRSEQ-SRA also have excellent scale and subscale internal reliability (αs = 0.92–0.99). Conclusions The DRSEQ-SRA is a short, 9-item, measure of adolescent drinking-refusal self-efficacy which demonstrates both reliability and validity. A significant advantage is brevity. The DRSEQ-SRA may be a valuable tool for identifying risk of adolescent drinking and prevention/treatment planning in settings where survey administration time is critical.

      Introduction Research has shown that African Americans gain more than average weight after smoking cessation. However, African Americans have been underrepresented in post-cessation weight gain research. The current study examined 1) the pattern of weight gain and 2) the association between smoking status and weight gain in a sample of African Americans seeking smoking cessation treatment. Methods Data were drawn from a randomized controlled trial testing the efficacy of a 4-week culturally specific smoking cessation cognitive behavioral therapy (CBT) intervention among African American smokers (N = 342). Weight was measured and self-reported smoking status was biochemically verified at baseline, end of counseling, 3-, 6-, and 12-month follow-ups. Random effects multilevel modeling was used to examine weight gain over twelve months post CBT, and a fully unconditional model tested the pattern of weight gain over time. Smoking status was included as a time-varying factor to examine its effect on weight gain, controlling for potential confounding variables. Results Weight significantly increased among those who remained abstinent over 12 months post CBT [average gain of seven lbs. (three kg)]. Controlling for covariates, abstinence was predictive of the rate of weight gain for those with high weight concern. Conclusions Weight gain among African American abstainers was comparable to the average post-cessation weight gain observed among the general population. It is possible that exposure to CBT (culturally specific or standard) may have mitigated excessive weight gain. Future research should assess predictors of weight gain in African American smokers to inform future smoking cessation interventions and help elucidate factors that contribute to tobacco- and obesity-related health disparities.

      Introduction Caffeine is a common psychoactive substance with a documented addictive potential. Caffeine withdrawal has been included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), but caffeine use disorder (CUD) is considered to be a condition for further study. The aim of the current study is (1) to test the psychometric properties of the Caffeine Use Disorder Questionnaire (CUDQ) by using a confirmatory factor analysis and an item response theory (IRT) approach, (2) to compare IRT models with varying numbers of parameters and models with or without caffeine consumption criteria, and (3) to examine if the total daily caffeine consumption and the use of different caffeinated products can predict the magnitude of CUD symptomatology. Methods A cross-sectional study was conducted on an adult sample (N = 2259). Participants answered several questions regarding their caffeine consumption habits and completed the CUDQ, which incorporates the nine proposed criteria of the DSM-5 as well as one additional item regarding the suffering caused by the symptoms. Results Factor analyses demonstrated the unidimensionality of the CUDQ. The suffering criterion had the highest discriminative value at a higher degree of latent trait. The criterion of failure to fulfill obligations and social/interpersonal problems discriminate only at the higher value of CUD latent factor, while endorsement the consumption of more caffeine or longer than intended and craving criteria were discriminative at a lower level of CUD. Total daily caffeine intake was related to a higher level of CUD. Daily coffee, energy drink, and cola intake as dummy variables were associated with the presence of more CUD symptoms, while daily tea consumption as a dummy variable was related to less CUD symptoms. Regular smoking was associated with more CUD symptoms, which was explained by a larger caffeine consumption. Conclusions The IRT approach helped to determine which CUD symptoms indicate more severity and have a greater discriminative value. The level of CUD is influenced by the type and quantity of caffeine consumption.

      Background The comorbidity of depressed mood and college student drinking causes consequences for both the individual and society. Aspects of parenting have been shown to be important for college students' well-being. While some interventions are beginning to address this population, few studies have examined how parental monitoring impacts the relationship between depressed mood, alcohol use, and related consequences. The present study examined whether perceived parental monitoring moderated the relationship between depressed mood and alcohol use and related problems. Methods Students (N = 796) completed a survey during the fall semester of their first two years of college at a large, public university assessing drinking and related negative consequences, maternal and paternal monitoring, and depressed mood. Results Results revealed that maternal and paternal monitoring moderated the relationship between depressed mood and typical weekly drinking, and depressed mood and consequences (i.e., self-perception, self-care, blackouts). Conclusions Interventions should be tailored to parents based on considerations of both student mental health and alcohol use.

      Objectives The present study examined (both cross-sectionally and prospectively) the mediational role of college alcohol beliefs in the relationship between impulsivity-related traits and alcohol outcomes (i.e., alcohol use and negative consequences) among college student drinkers from the United States (U.S.), Spain, and Argentina. Method A sample of 1429 (U.S. = 733, Spain = 292, Argentina = 404) drinkers (at least one drinking episode within the previous month) completed the baseline survey, and 242 drinkers completed the follow-up. To test study aims, a cross-sectional model was first employed to examine whether the proposed double-mediated paths (i.e., each dimension of impulsivity → college alcohol beliefs → alcohol use → negative alcohol-related consequences) extends across samples with different cultural backgrounds (i.e., structural invariance testing). A longitudinal model was then conducted to assess if college alcohol beliefs prospectively mediate the associations between trait impulsivity and alcohol outcomes. Results College alcohol beliefs were concurrently and prospectively associated with both greater alcohol use and increased number of negative alcohol-related consequences. These internalized beliefs about college student drinking culture significantly mediated the effects of several distinct impulsivity-related traits on alcohol-related outcomes including urgency (positive and negative), sensation seeking, and perseverance. These findings were invariant across gender and across three countries (Argentina, Spain, and the U.S.). Conclusions Our findings highlight the modulatory role of cognitive factors on problematic alcohol use among college students with different cultural backgrounds. Our results suggest that, despite the cultural differences exhibited by these three countries, the unique and mediational effects of college alcohol beliefs appear relatively universal.

      Aims The present study was divided into two different stages that sought to develop (Stage 1) and validate (Stage 2) the Argentinean-version of the Pregaming Motives Questionnaire (PMQ-Arg), a new, ecologically valid measure to assess pregaming (i.e., the consumption of alcohol prior to attending a social/sporting event where alcohol may or may not be available) motives among Spanish-speaking youth. Method: Two separate samples of Argentinian young adults (all last-year pregamers) were recruited by disseminating an invitation through online social networks and e-mail listings. Results In Stage 1, a total of 635 participants answered an open-ended question about their reasons for pregaming. In Stage 2 (n =361), exploratory factor analysis was conducted with the preliminary set of high-quality, high-frequency pregaming motives that were obtained in Stage 1, yielding a final 23-item measure that was grouped in four factors: (i) Intoxication and Fun, (ii) Gathering and Social Enhancement, (iii) Going with the Flow, and (iv) Beverage Preference. Despite some broad similarities with measures that were developed with U.S. young adults, the present results indicated that the narrow content of some items of the PMQ-Arg were somewhat unique, possibly reflecting cultural differences between the United States and Argentina. The findings supported the adequate reliability, discriminant validity, convergent validity, and criterion-related validity of PMQ-Arg scores. Conclusions The findings suggest that the PMQ-Arg meets the psychometric requirements of validity and reliability for its use to assess reasons for pregaming among Spanish-speaking youth.

      Introduction Previous research has shown reductions in cigarette consumption during the pre-quit period of exercise-aided smoking cessation interventions. Smoking topography and sensation patterns during this period is unknown and may provide valuable insight into compensation and cessation readiness. Methods Female smokers (N = 236, M age = 43, M cigarettes/day = 17.0) enrolled in an exercise-aided smoking cessation intervention self-reported daily cigarette use and cigarette sensory experiences. Breath carbon monoxide and smoking topography data were collected during the period leading up to the targeted quit date (i.e., baseline, week 1, and week 3), which was set for week 4. Results Repeated measures ANOVAs revealed that cigarette consumption (p < 0.001, eta = 0.32), carbon monoxide (p < 0.001, eta = 0.14), puff duration (p = 0.01, eta = 0.05), smoking satisfaction (p < 0.001, eta = 0.34), psychological reward (p < 0.001, eta = 0.43), enjoyment of respiratory tract sensations (p < 0.001, eta = 0.29), and craving (p < 0.001, eta = 0.39) decreased, whereas average puff flow (p = 0.01, eta = 0.05) increased. Conclusions This is the first study to establish that regular exercise during the pre-quit period served as a conduit for facilitating behavioral and sensory harm reduction with cigarettes. Furthermore, the pattern of change observed between cigarette consumption and smoking topography does not support compensation. These findings imply that female smokers who exercise prior to a quit attempt are in a favourable state to achieve cessation.

      Drinking protective behavioral strategies (PBS) have been associated with reductions in alcohol use and alcohol-related consequences in young adults. PBS subscales, Limiting/Stopping (LS), Manner of Drinking (MOD), and Serious Harm Reduction (SHR), have been examined in the literature; LS, MOD, and SHR have mixed support as protective factors. Understanding moderators between PBS and alcohol use and related consequences is an important development in PBS research in order to delineate when and for whom PBS use is effective in reducing harm from alcohol use. Perceptions of vulnerability to negative consequences, included in health-risk models, may be one such moderator. The current study examined whether two types of perceived vulnerability (perceived vulnerability when drinking; perceived vulnerability in uncomfortable/unfamiliar situations) moderated the relations between LS, MOD, SHR strategies and alcohol use and related negative consequences. High-risk young adults (N = 400; 53.75% female) recruited nationally completed measures of PBS, alcohol use and related consequences, and measures of perceived vulnerability. Findings demonstrated that perceived vulnerability when drinking moderated the relations between MOD strategies and alcohol use. The interactions between perceived vulnerability when drinking and PBS did not predict alcohol-related consequences. Perceived vulnerability in unfamiliar/uncomfortable social situations moderated relations between MOD strategies and both alcohol use and related negative consequences; no other significant interactions emerged. Across both perceived vulnerability types and MOD strategies, those with the highest levels of perceived vulnerability and who used MOD strategies the most had the greatest decrements in alcohol use and related negative consequences. Prevention and intervention implications are discussed.

      Background and aims Problematic internet use (PIU; otherwise known as Internet Addiction) is a growing problem in modern societies. There is scarce knowledge of the demographic variables and specific internet activities associated with PIU and a limited understanding of how PIU should be conceptualized. Our aim was to identify specific internet activities associated with PIU and explore the moderating role of age and gender in those associations. Methods We recruited 1749 participants aged 18 and above via media advertisements in an Internet-based survey at two sites, one in the US, and one in South Africa; we utilized Lasso regression for the analysis. Results Specific internet activities were associated with higher problematic internet use scores, including general surfing (lasso β: 2.1), internet gaming (β: 0.6), online shopping (β: 1.4), use of online auction websites (β: 0.027), social networking (β: 0.46) and use of online pornography (β: 1.0). Age moderated the relationship between PIU and role-playing-games (β: 0.33), online gambling (β: 0.15), use of auction websites (β: 0.35) and streaming media (β: 0.35), with older age associated with higher levels of PIU. There was inconclusive evidence for gender and gender × internet activities being associated with problematic internet use scores. Attention-deficit hyperactivity disorder (ADHD) and social anxiety disorder were associated with high PIU scores in young participants (age ≤ 25, β: 0.35 and 0.65 respectively), whereas generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD) were associated with high PIU scores in the older participants (age > 55, β: 6.4 and 4.3 respectively). Conclusions Many types of online behavior (e.g. shopping, pornography, general surfing) bear a stronger relationship with maladaptive use of the internet than gaming supporting the diagnostic classification of problematic internet use as a multifaceted disorder. Furthermore, internet activities and psychiatric diagnoses associated with problematic internet use vary with age, with public health implications.

      Emotion regulation difficulties (ERD) are known to underlie mental health conditions including anxiety and depressive disorders and alcohol use disorder (AUD). Although AUD, mood, and anxiety disorders commonly co-occur, no study has examined the association between these disorders and ERD among AUD outpatients. In the current study, emotion regulation (ER) scores of AUD individuals with no co-occurring mental health condition were compared to the ER scores of individuals who met diagnostic criteria for co-occurring mood and/or anxiety disorders. Treatment-seeking AUD individuals (N =77) completed measures of emotion regulation, alcohol use and psychological functioning prior to beginning a 12-week outpatient cognitive-behaviorally oriented alcohol treatment program. Individuals were classified as having no co-occurring mood or anxiety disorder (AUD-0, n =24), one co-occurring disorder (AUD-1, n =34), or two or more co-occurring disorders (AUD-2, n =19). Between-group differences in emotion regulation, quantity/frequency of alcohol consumption, positive and negative affect, affective drinking situations, negative mood regulation expectancies, distress tolerance, alexithymia, trait mindfulness, and psychological symptom severity were examined. Compared with the AUD-0 group, the AUD-2 group reported significantly greater ERD, psychiatric distress and alcohol consumption, more frequent drinking in response to negative affect situations, greater interference from negative emotions, and less use of mindfulness skills. The AUD-1 group differed from AUD-0 group only on the DERS lack of emotional awareness (Aware) subscale. Emotion regulation scores in the AUD-0 group were comparable to those previously reported for general community samples, whereas levels of ERD in the AUD-1 and AUD-2 were similar to those found in other clinical samples. Implications for the inclusion of ER interventions among AUD patients who might most benefit from such an intervention are discussed.

      Due to the current prolonged conflicts in Iraq and Afghanistan, members of the United States National Guard and Reserve have shifted from a historically support-based role to an integral segment of combat efforts. Clinical and epidemiological research studies conducted on both civilian and military populations have documented high rates of comorbidity of stress disorders and substance use disorders. It is widely understood that excessive alcohol use is an issue among military personnel. The aim of this paper is to describe risk factors for alcohol-related serious consequences in a study of Army National Guard service members, as well as the role of resilience in protecting against these risks. Members of the National Guard (N=320) participated in the survey. We conducted a multiple regression to predict alcohol-related serious consequences and a simple moderation analysis was performed. After controlling for race, education, and deployment history, several variables emerged as significant predictors of alcohol-related consequences. Higher stressors, lower resilience, younger age, being unmarried and not living as married, being male, and identifying as non-Hispanic were associated with higher levels of serious alcohol-related consequences. Results revealed that resilience significantly moderated the relationship between stress and alcohol-related consequences. This study furthers our understanding of the alcohol-stress relationship by contextualizing it in terms of behaviors related to alcohol, as opposed to measuring consumption only. Most importantly, our work extends prior research in its examination of resilience as a moderator of the relationship between stress and serious alcohol-related consequences.

      Servicewomen exposed to traumatic stressors over the course of their military service are at increased risk of developing symptoms of substance use disorder (SUD) and posttraumatic stress (PTS). They are also at risk for exposure to military sexual assault (MSA), which is also associated with SUD and PTS symptomology. Research is unclear about the incremental contributions of different forms of traumatic stressors on co-occurring SUD and PTS symptomology. In this study we examined the independent and combined effects of MSA and other military stressors on SUD and PTS symptomology in a sample of female veterans (N =407). Results indicate that MSA and other military stressors exhibit incremental effects on SUD and PTS symptomology. Results further suggest that women exposed to both MSA and other military stressors are at increased risk for developing co-occurring SUD and PTSD. These findings extend previous research on comorbid SUD and PTSD, highlighting the cumulative effects of traumatic stressors on posttraumatic psychopathology, and have implications for future research and clinical practice with female veterans.

      Introduction Previous studies have found serotonergic pathway genes have inhibitory effects on dopamine system which may influence smoking addiction. This study examined the associations of serotonergic pathway genes (serotonergic receptor genes, solute carrier family 6 member4 and tryptophan hydroxylase gene) with smoking cessation. Materials and methods Male current and former smokers (n =819) were recruited from 17 villages of three counties in Shandong province, China. DNA was extracted from the blood samples. Eleven single nucleotide polymorphisms (SNPs) in serotonergic pathway genes were genotyped. Multiple logistic regression was used to assess associations between SNPs and smoking cessation. Pearson's χ2 test was performed to explore associations of haplotypes with smoking cessation. Multiple logistic regression was used to detect the interaction between SNPs on smoking cessation. Results In multiple logistic regression, rs1042173 of Solute carrier family 6 member 4 was significantly related to smoking cessation in additive and dominant model (p =0.03 and 0.02, respectively). Rs4570625 of tryptophan hydroxylase 2 was significantly associated with smoking cessation in dominant model (p =0.03). Nine significant interactions were detected between SNPs in serotonergic pathway genes. Conclusions The present study reveals that serotonergic pathway genes were significantly related to smoking cessation. Future research should expand upon these findings to confirm them.

      Social cognitive factors such as perceived norms and personal attitudes toward alcohol consumption are reliable predictors of alcohol use and related problems. The current study aimed to evaluate the relative importance of one's attitude toward alcohol use as a unique and important predictor of drinking related outcomes when directly compared to perceived descriptive and injunctive norms. Participants were mandated students (n =568; 28% female) who violated a campus alcohol policy and received a Brief Motivational Intervention. Analyses included the use of linear regression for prospective predictions to evaluate the relative importance of predictors which included perceived descriptive norms and injunctive norms, and attitudes toward moderate and heavy alcohol use. Overall, the results indicate that one's attitude toward heavy alcohol use is a stronger predictor of drinks per week, binge frequency, as well as alcohol related problems when directly compared to norms. Thus, the findings of the current study provide a compelling rationale for incorporating attitudes in the development and refinement of intervention strategies.

      Introduction Adolescent and young adult binge drinking is strongly associated with perceived social norms and the drinking behavior that occurs within peer networks. The extent to which an individual is influenced by the behavior of others may depend upon that individual's resistance to peer influence (RPI). Methods Students in their first semester of college (N =1323; 54.7% female, 57% White, 15.1% Hispanic) reported on their own binge drinking, and the perceived binge drinking of up to 10 important peers in the first-year class. Using network autocorrelation models, we investigated cross-sectional relationships between participant's binge drinking frequency and the perceived and actual binge drinking frequency of important peers. We then tested the moderating role of RPI, expecting that greater RPI would weaken the relationship between perceived and actual peer binge drinking on participant binge drinking. Results Perceived and actual peer binge drinking were statistically significant predictors of participant binge drinking frequency in the past month, after controlling for covariates. RPI significantly moderated the association between perceptions of peer binge drinking and participant's own binge drinking; this association was weaker among participants with higher RPI compared to those with lower RPI. RPI did not interact with the actual binge drinking behavior of network peers. Conclusions RPI may function to protect individuals from the effect of their perceptions about the binge drinking of peers, but not from the effect of the actual binge drinking of peers.

      Introduction Individuals may compensate for workplace smoking bans by smoking more before or after work, or escaping bans to smoke, but no studies have conducted a detailed, quantitative analysis of such compensatory behaviors using real-time data. Methods 124 daily smokers documented smoking occasions over 3weeks using ecological momentary assessment (EMA), and provided information on real-world exposure to smoking restrictions and type of workplace smoking policy (full, partial, or no bans). Mixed modeling and generalized estimating equations assessed effects of time of day, weekday (vs weekend), and workplace policy on mean cigarettes per hour (CPH) and reports of changing location to smoke. Results Individuals were most likely to change locations to smoke during business hours, regardless of work policy, and frequency of EMA reports of restrictions at work was associated with increased likelihood of changing locations to smoke (OR=1.11, 95% CI 1.05–1.16; p <0.0001). Workplace smoking policy, time block, and weekday/weekend interacted to predict CPH (p <0.01), such that individuals with partial work bans –but not those with full bans - smoked more at night (9pm – bed) on weekdays compared to weekends. Conclusions There was little evidence that full bans interfered with subjects' smoking during business hours across weekdays and weekends. Smokers largely compensate for exposure to workplace smoking bans by escaping restrictions during business hours. Better understanding the effects of smoking bans on smoking behavior may help to improve their effectiveness and yield insights into determinants of smoking in more restrictive environments.

      Objectives Switching from combustible tobacco cigarettes to electronic cigarettes (e-cigs) may or may not help smokers to reduce cigarette consumption and toxicant exposure. This pilot study investigated the effects of asking smokers to switch to e-cigs for 6weeks on smoking, exhaled carbon monoxide (CO) concentration, dependence, and motivation to quit smoking. Methods Non-treatment seeking daily smokers (n=18) were given free e-cigs and instructed to use them instead of smoking cigarettes for 6weeks. Smokers were assessed at baseline, weekly for 6weeks, and at 8 and 10weeks for cigarettes/day, e-cig use, CO, cigarette dependence, and Contemplation Ladder. Results All participants completed 6weeks; 17 completed 10weeks. At Week 6, cigarettes/day were reduced by two-thirds and CO by 45% from baseline (p's<.001), with reductions maintained at Week 10 (p's<.005). Cigarette dependence scores were a third lower at Weeks 6 (p<.002) and 10 (p<.001) than at baseline. Contemplation Ladder scores were higher at Weeks 6 and 10 (p's<.001) than at baseline. All these statistical effect sizes were large. At Week 6, number of reasons not to use e-cigs increased (p<.011). Conclusions Results show preliminary evidence for beneficial effects of short-term switching to e-cigs by non-treatment seeking smokers in terms of reduced smoke toxicant exposure and cigarette dependence, and increased motivation to quit, all maintained at least 4weeks after free e-cigs were no longer provided.

      Our recent work (Boyle, Earle, LaBrie, & Smith, 2017) showed that the efficacy of personalized normative feedback-based (PNF) college alcohol interventions can be improved through the addition of gamified elements including points, chance, competition, and personal avatars. However, participants in that study were compensated with subject pool credit. In the current study, we piloted an upgraded, smartphone-based version of the game, which was designed to be truly self-sustaining (i.e., engaging enough that students play voluntarily without the presence of external motivators). First-year students were invited to play the game weekly for six rounds, with participants submitting and voting on their own questions each week and receiving a novel type of feedback in addition to standard descriptive PNF: opposite peers' judgments of participants' self-reported drinking behavior, or reflective norms. With no play-based incentives, 222 first-year college students voluntarily played the game, CampusGANDR. ANCOVA models revealed that, relative to participants randomized to receive feedback on control topics during the three intervention rounds, those who received both descriptive and reflective feedback on peer alcohol use had significantly reduced normative perceptions and reduced alcohol use two months post intervention. This was especially true among heavy drinkers. The results suggest that our gamified “GANDR” approach shows promise as a self-sustaining intervention and, further, that high-risk drinkers may benefit disproportionately from this methodology. Thus, self-sustaining interventions represent an encouraging avenue for future research and development and may hold the potential to impact risky college drinking on a large scale.

      Introduction A number of mechanisms have been proposed to explain how exercise attenuates cravings among temporarily abstinent smokers; however, research has presented mixed findings. The aim of this study was to further investigate the mechanistic role of positive and negative affect and cortisol in the exercise-craving reduction relationship. Methods Adult smokers (N =110, male=56, M age=33.1, M cigarettes/day=15.4) provided baseline affective and cortisol data (T1). After an 18-h period of abstinence, participants were randomized to a passive sitting (PSG) or moderate exercise group (MEG; 40–68% of heart rate reserve) for 10min. Affect and cortisol data were also collected immediately before (T2) and after (T3) the condition. Results The smoking abstinence manipulation increased cravings (p <0.001, eta=0.40) and negative affect (p <0.001, eta=0.17), as well as decreased positive affect (p <0.001, eta=0.08) and cortisol (trending, p =0.07, η2=0.04). As expected, a significant reduction in cravings from T2 to T3 was found for MEG but not PSG (p <0.001, eta=0.25). Mediation was tested using Sobel and bootstrapping tests with residual change scores of mediators and cravings. Findings showed that both positive and negative affect, but not cortisol, mediated the relationship between exercise and cravings. Conclusions Understanding the mechanisms by which exercise induces craving reductions will better allow researchers and healthcare professionals to infer causality and implement interventions guided by the processes that yield such desirable outcomes.

      Objective We prospectively examined whether subjective intoxication serves as a risk factor for experiencing alcohol-induced blackouts. We then examined whether subjective intoxication and/or blackouts predicted motivation to decrease their drinking, and whether this motivation to change would promote future changes in drinking behavior. Method Participants (N =1854, 62.1% female, 53.2% Caucasian, M age =21.8) were recruited the summer prior to matriculating into a large, public university to complete a 6-year longitudinal study. Self-reported motivation to decrease their drinking behavior, their frequency of blackouts, quantity of alcohol consumption, and subjective intoxication (i.e., feeling drunk) were assessed annually during the transition out of college (Years 4–6). Results In a cross-lagged model, subjective intoxication (i.e., feeling drunk) prospectively predicted experiencing blackouts (p <0.001). Controlling for both objective (e.g., quantity) and subjective intoxication, blackouts at Year 4 predicted greater motivation to decrease drinking behavior at Year 5 (p <0.01), but this motivation did not predict less quantity of alcohol use by Year 6 (p =0.076). Conclusions Subjective intoxication is a robust predictor of blackouts across time. Additionally, blackouts are modest, developmentally-limited predictors of motivation to change drinking behavior, but blackouts do not predict future behavior change.

      Introduction Contingency management (CM) is effective for promoting smoking abstinence; however, moderators and mediators of CM treatment efficacy in young adult populations are under-explored. We leveraged fine-grained data from a large randomized controlled trial: 1) to determine whether early attainment of sustained abstinence mediated the effect of treatment on abstinence; 2) to test whether heavy drinking moderated the effect of treatment on abstinence; and 3) to test a serial mediation model of the effects of drinking during early treatment on sustained smoking abstinence. Methods College student smokers (N=110) were randomized to receive either CM treatment or noncontingent reinforcement (NR) over a 21-day treatment period. All participants received $5 for providing twice-daily breath carbon monoxide (CO) samples. In CM, additional money was provided for samples that indicated smoking reduction (Initial Phase; first 7days), and for samples ≤5ppm (Abstinence Phase; following 14days). Results CM treatment led to greater sustained abstinence relative to NR. Longer sustained abstinence in the Initial Phase partially mediated the effect of treatment on sustained abstinence in the Abstinence Phase. Heavier pretreatment drinkers had shorter periods of sustained abstinence in the Abstinence Phase; this effect was greater in CM. A serial mediation model determined that increased drinking during the Initial Phase led to decreased sustained abstinence, which then led to decreased sustained abstinence in the Abstinence Phase. Conclusions These data provide a greater understanding of how heavy drinking and early sustained abstinence may affect success during treatment in young adults undergoing contingency management treatment for smoking.

      Background Smoking rates are disproportionately high among adults with mental health conditions (MHC), and recent research suggests that among former smokers, those with MHC are more likely to use electronic nicotine delivery systems (ENDS). This study investigated reasons for ENDS use and related risk perceptions among individuals with versus without MHC. Methods Among adult current ENDS users (n =550), associations between self-reported MHC diagnoses and motives for ENDS use and ENDS risk perceptions were examined, stratified by smoking status. Results There were no significant associations between MHC status and ENDS motives or perceptions in the overall sample. However, current smokers with MHC indicated thinking more about how ENDS might improve their health, and former smokers with MHC reported thinking less about how ENDS might harm their health, compared to their counterparts without MHC. Former smokers with MHC rated several reasons for ENDS use (e.g., less harmful than regular cigarettes; to quit smoking; appealing flavors) as more important than did those without MHC. Conclusions Current and former smokers with MHC may be especially optimistic about health benefits of ENDS. However, they might also be prone to health risks of continued ENDS use or concurrent use with traditional cigarettes. It will be important for public health messaging to provide this population with accurate information about benefits and risks of ENDS.

      Background Methamphetamine has long been considered as a neurotoxic substance causing cognitive deficits. Recently, however, the magnitude and the clinical significance of the cognitive effects associated with methamphetamine use disorder (MUD) have been debated. To help clarify this controversy, we performed a meta-analysis of the cognitive deficits associated with MUD. Methods A literature search yielded 44 studies that assessed cognitive dysfunction in 1592 subjects with MUD and 1820 healthy controls. Effect size estimates were calculated using the Comprehensive Meta-Analysis, for the following 12 cognitive domains: attention, executive functions, impulsivity/reward processing, social cognition, speed of processing, verbal fluency/language, verbal learning and memory, visual learning and memory, visuo-spatial abilities and working memory. Results Findings revealed moderate impairment across most cognitive domains, including attention, executive functions, language/verbal fluency, verbal learning and memory, visual memory and working memory. Deficits in impulsivity/reward processing and social cognition were more prominent, whereas visual learning and visuo-spatial abilities were relatively spared cognitive domains. A publication bias was observed. Discussion These results show that MUD is associated with broad cognitive deficits that are in the same range as those associated with alcohol and cocaine use disorder, as recently shown by way of meta-analysis. The prominent effects of MUD on social cognition and impulsivity/reward processing are based on a small number of studies, and as such, these results will need to be replicated. The functional consequences (social and occupational) of the cognitive deficits of methamphetamine will also need to be determined.
