ABSTRACT
Pre-exposure prophylaxis (PrEP) use may be associated with condom use decisions. The current investigation examined sexual decision-making in the context of PrEP among young adult men who have sex with men (MSM) between 18 and 30 years old, using an explanatory sequential mixed methods design. For the quantitative aim, 99 MSM currently taking PrEP (i.e., PrEP-experienced) and 140 MSM not currently taking PrEP (i.e., PrEP-naive) completed an online survey, including the Sexual Delay Discounting Task (SDDT), which captures likelihood of condom use. For the qualitative aim, 15 people from each group were interviewed about their (1) conceptualizations of risky sex and (2) ways they manage their sexual risk. Participants were, on average, 25.69 years old (SD = 3.07) and 64% White. Results from the quantitative aim revealed, controlling for covariates, PrEP-experienced participants exhibited significantly lower likelihood of (1) using an immediately available condom and (2) waiting for a delayed condom (i.e., sexual delay discounting) compared to PrEP-naive participants. Qualitative themes explaining what young adult MSM consider to be risky sex included: (1) any sex as risky sex, (2) risky sex as "sex without a conversation," and (3) risky sex as sex with risk for physical harm. Themes on ways young adult MSM manage sexual risk were classified as proactive, reactive, and passive. Results suggest that PrEP use is related to condom use decisions. Taken together, quantitative differences in sexual delay discounting, but qualitatively similar conceptualizations and management of risky sex, suggest that the SDDT may be a useful tool in sex research to capture processes (i.e., delay discounting) underlying sexual decision-making that may be missed by traditional self-reports. Implications of results, including potentially providing (good quality) condoms with every PrEP prescription, and future research topics are discussed.

Optimal adherence to pre-exposure prophylaxis (PrEP) is critical, but challenging. Men who have sex with men and transgender women have high rates of HIV incidence and substance use. Substance use is associated with reduced adherence to other medications, but associations between substance use and adherence to PrEP are less clear. Thus, the current review 1) systematically evaluates the measurement of substance use and PrEP adherence in studies examining both and 2) summarizes reported findings. Peer-reviewed articles published between 2010 - April 2021 examining associations between substance use and PrEP adherence were reviewed. Fifty studies met inclusion criteria. Assessment of substance use (i.e., mostly via self-reports at baseline) and PrEP adherence (i.e., often via tenofovir diphosphate [TFV-DP] concentration levels at follow-up) varied considerably across studies. Many studies used categorical variables (e.g., substance use: yes/no). Studies using TFV-DP levels defined adherence consistently (i.e., TFV-DP ≥ 700 fmol/punch), with slight variations. Qualitative studies (n = 10) indicated that substance use (mainly alcohol) is related to poorer PrEP adherence. While quantitative findings to date are equivocal for alcohol, there is a pattern of findings linking stimulant use with poorer PrEP adherence. This review reveals four methodological gaps, which can be addressed in future research by: 1) use of uniform benchmarks for substance use measures, 2) prospective assessment for substance use, 3) use of continuous outcome variables wherever possible, and 4) more extensive consideration of potential confounders. Addressing these methodological gaps may help us reach more definitive conclusions regarding associations between substance use and PrEP adherence.

BACKGROUND: Alcohol misuse is highly prevalent in the United States and results in a huge financial and public health burden. Current alcohol reduction treatments are underused, and there is a critical need for innovation in the field. Transdermal alcohol biosensors measure alcohol use passively and continuously and may be helpful tools in alcohol interventions. To date, however, alcohol biosensors have not been widely used to directly intervene on alcohol use. There is a new wrist-worn biosensor that could be used to help people reduce their drinking, although it is unclear how best to incorporate such a device into an alcohol intervention. OBJECTIVE: We aimed to identify desired features that would be acceptable and helpful in a wrist-worn biosensor-based alcohol intervention for adults who drink heavily. METHODS: Participants were recruited through an alcohol contingency management study, a contact registry, and participant referral. To qualify, participants had to be aged at least 40 years, report drinking at least twice per week, and indicate interest in reducing their drinking. We conducted a semistructured interview with each participant via Zoom (Zoom Video Communications, Inc). The interview guide addressed general thoughts on the wrist-worn biosensor, how participants thought a wrist-worn biosensor could be used to help people quit or reduce drinking, types of information that participants would want to receive from the biosensor, how they would want to receive this information, and how they thought this information could be used to change their behavior. Interviews were transcribed verbatim and analyzed using thematic analysis. RESULTS: The sample comprised 20 adults (mean age 55.1, SD 6.1 years; 11/20, 55%, women; and 17/20, 85%, Black). Of the 20 participants, 9 (45%) had previous experience with the Secure Continuous Remote Alcohol Monitor continuous alcohol monitoring ankle biosensor from participating in an alcohol contingency management study. The desirable features could be grouped into 5 main themes: features that would influence willingness to use the biosensor (it should look attractive and be both comfortable to wear and accessible), personalized messaging (personalized biosensor-based prompts and feedback could be helpful), preference for time wearing the biosensor (for some, just wearing the biosensor could have an intervention effect), sharing data with others (this was appealing to many but not to all), and mental health support (many felt that mental health support could be incorporated into the biosensor). CONCLUSIONS: Five main themes that would maximize interest in using a wrist-worn biosensor for alcohol intervention were identified. Taken together, the identified themes could inform the development of a just-in-time adaptive intervention that uses a wrist-worn biosensor to help adults who drink heavily reduce their alcohol use.

OBJECTIVE: Naltrexone is an effective treatment for heavy drinking among young adults. Laboratory-based studies have shown that naltrexone dampens the subjective response to alcohol and craving. However, few studies have tested naltrexone's dynamic, within-person effects on subjective response and craving among young adults in natural drinking environments. METHODS: Using daily diary data from a randomized, placebo-controlled study of naltrexone's efficacy in young adults, we examined the between-person effects of treatment condition (i.e., naltrexone vs. placebo) and medication dosage (i.e., daily, targeted, and daily + targeted) on the subjective response to alcohol and craving on drinking days. Multilevel mediation models predicted subjective response and craving from treatment condition (between-person) and medication dosage (within-person), accounting for drinking levels. All effects were disaggregated within and between persons. RESULTS: At the between-person level, naltrexone directly blunted intense subjective effects (i.e., "impaired", "drunk") and indirectly blunted subjective effects through reduced drinking. Naltrexone was not associated with craving. Between-person effects were not significant after alpha correction, but their effect sizes (bs = 0.14 to 0.17) exceeded the smallest effect size of interest. At the within-person level, taking two (vs. 1) pills was associated with heavier drinking, and taking one (vs. 0) pill was associated with lighter drinking, and lighter drinking was associated with a lower subjective response and craving. Treatment condition did not moderate the within-person effects of dosing on outcomes. CONCLUSIONS: Our findings suggest that the direct between-person effect of naltrexone was largest on intense subjective responses, blunting feelings of being "drunk" and "impaired". Future research using momentary (rather than daily) assessments could confirm and extend these findings.

Alcohol use is associated with poor outcomes among people living with HIV (PLWH), but it remains unclear which alcohol use measures best predict future HIV viral non-suppression over time. This study aimed to compare the ability of five alcohol use measures to predict risk of suboptimal HIV viral load trajectories over 36 months. We analyzed data from a cohort of PLWH in Florida including survey data linked to the state HIV surveillance system on prospective HIV viral loads over 36 months (n = 783; 66% male; 55% Black; Mage=46, SD = 11). Four trajectory patterns for HIV viral load were identified: consistently low (65.1%), decreasing (15.9%), increasing (10.6%), and consistently high (8.4%). Past year alcohol use frequency (OR = 2.1, CI:1.0-4.4), drinks consumed on a typical drinking day (OR = 2.2, CI:1.2-4.1), frequency of binge drinking (OR = 2.6, CI:1.3-5.2), and alcohol-related problems score (OR = 1.7, CI:1.1-2.7) were the measures predictive of the risk of future viral non-suppression above specific thresholds.
RESUMEN: El consumo de alcohol está asociado con malos resultados entre las personas que viven con el VIH (PLWH), pero aún no está claro qué medidas de consumo de alcohol predicen mejor la falta de supresión viral del VIH en el futuro con el tiempo. Este estudio tuvo como objetivo comparar la capacidad de cinco medidas de consumo de alcohol para predecir el riesgo de trayectorias subóptimas de la carga viral del VIH durante 36 meses. Analizamos datos de una cohorte de PLWH en Florida, incluidos datos de encuestas vinculadas al sistema estatal de vigilancia del VIH sobre posibles cargas virales del VIH durante 36 meses (n = 783; 66% hombres; 55% afroamericanos; Maños=46, SD = 11). Se identificaron cuatro patrones de trayectoria para la carga viral del VIH: consistentemente baja (65,1%), decreciente (15,9%), creciente (10,6%) y consistentemente alta (8,4%). Frecuencia de consumo de alcohol en el último año (OR = 2,1, IC: 1,04,4), bebidas consumidas en un día típico de consumo de alcohol (OR = 2,2, IC: 1,24,1), frecuencia de consumo excesivo de alcohol (OR = 2,6, IC: 1,35,2), y la puntuación de problemas relacionados con el alcohol (OR = 1,7, IC: 1,12,7) fueron las medidas predictivas del riesgo de no supresión viral futura por encima de umbrales específicos.

The Sexual Delay Discounting Task (SDDT; Johnson & Bruner, 2012) is a behavioral economic task that assesses sexual risk-taking by measuring likelihood of immediate and delayed condom use. The SDDT is ecologically valid and has been used to test effects of various substances on sexual risk-taking. However, considerable variety in implementation, analysis, and reporting of the SDDT may limit rigor and reproducibility of findings. The current review synthesized studies that used the SDDT to evaluate these possible variabilities systematically. A two-step search (citation-tracking and keyword-based search) was conducted to identify studies that met inclusion criteria (i.e., used the SDDT). Eighteen peer-reviewed articles met inclusion criteria. The SDDT has been implemented primarily in three populations: individuals who use cocaine, men who have sex with men, and college students. Comparable results across diverse populations support the SDDT's validity. A few studies administered substances before the SDDT. Evidence suggests that while cocaine and alcohol increased sexual risk-taking under some conditions, buspirone decreased preference for immediate condomless sex. There was also heterogeneity in the determination of data orderliness (i.e., outliers) and inconsistent reporting of task design and analysis. Considerable differences present in methodologic approaches could influence results. Reducing variation in the administration, analysis, and reporting of the SDDT will enhance rigor and reproducibility and maximize the task's tremendous potential.

Men who have sex with men (MSM) account for two-thirds of new HIV diagnoses. Pre-exposure prophylaxis (PrEP), a highly efficacious HIV preventive medication, is underutilized. Identifying correlates of PrEP awareness and attitudes may help increase PrEP use. Thus, we evaluated (1) PrEP awareness; (2) differences in awareness related to substance use and sociodemographics; (3) initial PrEP information sources; and (4) possible associations between information sources and PrEP-related attitudes.Young adult (ages 18-30) HIV-negative MSM from Southern U.S. undertook a web survey including questions about substance use, sexual behaviors, perceived HIV risk, and PrEP. Participants were recruited using in-person and online approaches between January 2018-January 2020.Of 506 participants, 89% were aware of PrEP. Participants with high alcohol consumption and greater perceived HIV risk had higher odds of PrEP unawareness with a trend for minority race/ethnicity. PrEP-aware participants reported high overall perceived safety, confidence in PrEP's efficacy, and low perceived difficulties with adherence though those with higher perceived HIV risk and individuals who used tobacco had less favorable attitudes. Most participants first heard about PrEP from the internet. There were no statistically significant differences in PrEP-related attitudes across initial information sources.Associations between substance use and racial/ethnic minority status and lack of PrEP awareness suggest priority subgroups for educational campaigns. Future campaigns may tailor outreach materials to the respective audience (e.g., Spanish materials for Hispanic people) and disseminate where individuals who use substances may be more likely to see them (e.g., liquor and convenience stores).Supplemental data for this article is available online at https://doi.org/10.1080/10826084.2022.2040030 .

BACKGROUND: Transdermal alcohol biosensors can objectively monitor alcohol use by measuring transdermal alcohol concentration (TAC). However, it is unclear how sociodemographic and clinical factors that influence alcohol metabolism are associated with TAC. The main aim of this study was to examine how sociodemographic factors (sex, age, race/ethnicity) and clinical factors (body mass index, liver enzymes: alanine aminotransferase [ALT] and aspartate transaminase [AST]), alcohol use disorder, and HIV status were associated with TAC while controlling for level of alcohol use. METHODS: We analyzed data from a prospective study involving contingency management for alcohol cessation among persons living with and without human immunodeficiency virus (HIV) that used the Secure Continuous Remote Alcohol Monitoring (SCRAM) biosensor. Forty-three participants (Mage = 56.6 years; 63% male; 58% people living with HIV) yielded 183 SCRAM-detected drinking days. Two indices derived from SCRAM: peak TAC (reflecting level of intoxication) and TAC area under the curve (TAC-AUC; reflecting alcohol volume)-were the main outcomes. Self-reported alcohol use (drinks/drinking day) measured by Timeline Followback was the main predictor. To examine whether factors of interest were associated with TAC, we used individual generalized estimating equations (GEE), followed by a multivariate GEE model to include all significant predictors to examine their associations with TAC beyond the effect of self-reported alcohol use. RESULTS: Number of drinks per drinking day (B = 0.29, p < 0.01) and elevated AST (B = 0.50, p = 0.01) were significant predictors of peak TAC. Positive HIV status, female sex, elevated AST, and number of drinks per drinking day were positively associated with TAC-AUC at the bivariate level, whereas only self-reported alcohol use (B = 0.85, p < 0.0001) and female sex (B = 0.67, p < 0.05) were significant predictors of TAC-AUC at the multivariate level. CONCLUSIONS: HIV status was not independently associated with TAC. Future studies should consider the sex and liver function of the participant when using alcohol biosensors to measure alcohol use.

Alcohol-using Black MSM (Men who have sex with men) are disproportionately impacted by HIV in the U.S.-particularly in the southern U.S.-despite the availability of antiretroviral therapy (ART). The purpose of this study was to summarize the current evidence on alcohol use and ART adherence among Black MSM in the U.S. and in the South and to identify future research needs. A systematic review was conducted using eight databases to identify relevant peer-reviewed articles published between January 2010 and April 2021. The authors also snowballed remaining studies and hand-searched for additional studies. Including both quantitative and qualitative studies, five published studies examined alcohol and ART adherence among Black MSM in the U.S. The search identified 240 articles, the study team reviewed 114 in full-text and determined that only five met the inclusion criteria. Three of the five included studies identified alcohol use as a barrier to ART adherence. In conclusions, the general lack of literature on HIV disparities among alcohol-using Black MSM in the U.S. (specifically in the South) indicates a critical need for research on this population's unique risks and needs to inform the development of tailored interventions.

Introduction: Among people living with HIV (PLWH), alcohol use can have negative impacts beyond HIV-related outcomes. The objectives of this study are to identify the most common alcohol-related consequences among PLWH in Florida and describe factors associated with experiencing more alcohol-related consequences. Methods: Data were collected from PLWH in the Florida Cohort study who drank at least monthly in the past year (n=397). Self-reported consequences were assessed by the 15-item Short Inventory of Problems Revised (SIP-2R). Nonparametric tests and a generalized estimating equation model with inverse probability of exposure weighting were used to evaluate associations between the total SIP-2R score and socio-demographics, mental health, and substance use while controlling for alcohol use. Results: Over half (56%) endorsed at least one consequence and 29% endorsed 5 or more consequences. The most common consequences were doing something they regretted and taking foolish risks (both endorsed by 37% of participants), both in the impulse control domain. After controlling for alcohol use and other covariates, homelessness and injection drug use remained significantly associated with greater SIP-2R scores. Conclusion: PLWH who are experiencing homelessness or injecting drugs could benefit from receiving additional screening for alcohol-related consequences if they report any alcohol use.

BACKGROUND: Alcohol consistently impairs response inhibition in the laboratory, and alcohol impairment of response inhibition may lead to excess consumption or increases in intoxicated risk behavior, both of which contribute to risk for alcohol-related problems. To our knowledge, no prior studies have examined relations between alcohol impairment of response inhibition and either impaired control over alcohol (i.e., inability to adhere to predetermined drinking limits) or real-world alcohol-related problems. The current study addressed this gap in the literature. METHODS: Young adult social drinkers (N = 215, 76% male) participated in a between-subjects, placebo-controlled alcohol challenge study and completed self-reports approximately 2 weeks later. Multilevel models were used to examine the hypothesis that alcohol impairment of response inhibition would indirectly lead to alcohol-related problems through impaired control over alcohol use. RESULTS: Greater alcohol-induced impairment of response inhibition and impaired control over alcohol use were both significant predictors of alcohol-related problems. However, greater alcohol-induced response inhibition was not a significant predictor of impaired control over alcohol use. CONCLUSIONS: To our knowledge, this is the first study demonstrating relationships between alcohol impairment of response inhibition and real-world alcohol-related problems and the first to address relationships between alcohol impairment of response inhibition and impaired control over alcohol use. These results suggest that impaired control over alcohol use may result from deficits in the trait ability to control behavior rather than deficits in alcohol-induced response inhibition. Regardless, results suggest that alcohol impairment of response inhibition and impaired control over alcohol are both worthwhile intervention targets.

Self-Discrepancy Theory (Higgins, 1987) predicts that the difference between the ideal and the actual self will be associated with impaired-control-over-drinking (IC; dysregulated drinking beyond one's own limits) as well as alcohol-related-problems. According to Slaney et al. (2001) perfectionism is a multi-faceted personality trait which represents both adaptive (e.g. high-standards) and maladaptive (e.g. discrepancy) aspects. In particular, discrepancy has been associated with poorer coping approaches, which may suggest a Self-Medication route to IC. Yet, to date, no one has examined whether drinking-motives (e.g., social, enhancement, coping and conformity) mediate the relations between discrepancy and high standards and alcohol-outcomes such as IC. We used a structural equation model to test indirect associations of discrepancy and high-standards to both heavy-episodic-drinking and alcohol-related-problems through the mediating mechanisms of drinking-motives and IC. Results supported the distinction between discrepancy and high-standards consistent with the Self-Medication Hypothesis (Hersh & Hussong, 2009). Discrepancy was associated with poorer alcohol-outcomes through greater coping-motives, conformity-motives and IC. In contrast, higher-standards were associated with fewer alcohol-outcomes through less coping-motives, conformity-motives, and IC. This study illustrates the importance of personality factors such as discrepancy in the development of problematic alcohol-use suggesting that it might be a good target for intervention.
ABSTRACT
AIMS: Subjective response to alcohol and impulsivity are both independent predictors of alcohol use and may be related risk factors for alcohol use disorders (AUDs). Recent findings suggest that more impulsive individuals may experience higher risk subjective response patterns at moderate-to-high doses of alcohol. However, whether these relationships are observable early in a drinking occasion remains an open question. This study examined multiple measures of impulsivity in relation to subjective response following low-dose alcohol. METHOD: Eighty-seven non-treatment-seeking heavy drinkers were enrolled in a placebo-controlled alcohol administration study testing the effects of NMDA receptor antagonist, Memantine. Baseline impulsivity assessments included the Cued Go/No-Go Task, Experiential Discounting Task, and Barratt Impulsiveness Scale, Version 11 (BIS-11). Following consumption of low-dose alcohol aimed to increase blood alcohol concentration (BAC) to 0.03%, subjective stimulation and sedation were measured using the Biphasic Alcohol Effects Scale. Models were tested to relate impulsivity measures to subjective response with a post hoc exploratory model exploring boredom as an alternate predictor. RESULTS: Increases in stimulation and sedation were observed following low-dose alcohol, but were not predicted significantly by impulsivity measures. Although greater impulsivity on the BIS-11 was a trend-level predictor of increased sedation, post hoc analyses suggested these results were an artifact of boredom. CONCLUSION: Although impulsivity did not predict subjective response to low-dose alcohol, the results suggest that small amounts of alcohol can produce a range of subjective effects, even among heavy drinkers. Future studies would benefit by examining subjective response across a range of BACs among both light and heavy drinkers.

BACKGROUND: Social Learning Theory suggests how one conceptualizes time will be passed from parent to child (Bandura & Walters, 1963). Through the lens of Behavioral Economics Theory (Vuchinich & Simpson, 1998), impaired control may be characterized as consuming alcohol as a form of immediate gratification as a choice over more distal rewards. Because impaired control reflects a self-regulation failure specific to the drinking situation, it may be directly related to time-perspectives. OBJECTIVES: This investigation explored whether or not the indirect influences of perceived parenting styles on alcohol use and related problems is mediated by both facets of time-perspective (e.g. hedonism, present-fatalism, future, past-positive, past-negative) and impaired control over drinking. METHODS: We examined a structural equation model with 391 (207 women; 184 men) college student drinkers. We used an asymmetric bias-corrected bootstrap technique to conduct mediational analyses (MacKinnon, 2008). RESULTS: Higher levels of past-positive time-perspective were indirectly linked to both less alcohol use and fewer alcohol-related problems through less impaired control. In contrast, higher levels of present-fatalism were indirectly linked to more alcohol use through more impaired control. Higher levels of father permissiveness and mother authoritarianism were indirectly linked to both more impaired control and alcohol use through more present-fatalism. In addition, higher levels of father authoritarianism were indirectly linked to more alcohol use through more hedonism. CONCLUSIONS/IMPLICATIONS: Our results support the notion that drinking beyond one's self-prescribed limits is associated with time-perspectives related to negative aspects of the parent-offspring socialization process, such as fatalism.

BACKGROUND: Anxiety sensitivity (AS) reflects an individual's belief that experiencing anxiety will cause illness or embarrassment, and may be a reason individuals self-medicate with alcohol. Harsh or indulgent parenting could contribute to the development of AS. We examined the direct and indirect associations between parenting styles and alcohol-related variables through AS and impaired control over drinking (IC; i.e., perceived failure to adhere to limits on alcohol consumption in the future). METHODS: A multiple-group structural equation model with 614 university students (344 men; 270 women) was examined. Structural invariance tests were conducted to evaluate moderation by gender. We used a bias corrected bootstrap technique to obtain the mediated effects. RESULTS: Father authoritarianism and mother permissiveness were directly linked to AS among women, whereas father permissiveness was directly linked to AS among men. This suggests unique parental influences based on gender regarding AS. While AS was directly linked to alcohol-related problems for both men and women, several gender-specific associations were found. AS was directly linked to IC for men but not for women. For men, father permissiveness was directly related to AS, and AS mediated the indirect link between father permissiveness and IC along both the heavy episodic drinking and alcohol-related problems pathways. Similar to other internalizing constructs (e.g., neuroticism and depression), higher AS was directly associated with less heavy episodic drinking but more alcohol-related problems. CONCLUSIONS: Our findings highlight the dangers of AS for men as an important correlate of under-controlled drinking behaviors. Additionally, permissive parenting of the same-gender parent was associated with AS, which is consistent with the gender-matching hypothesis. Together, these results underscore the importance of measuring the independent influence of both parents.

BACKGROUND: Young adult heavy drinking is an important public health concern. Current interventions have efficacy but with only modest effects, and thus, novel interventions are needed. In prior studies, heavy drinkers, including young adults, have demonstrated stronger automatically triggered approach tendencies to alcohol-related stimuli than lighter drinkers. Automatic action tendency retraining has been developed to correct this tendency and consequently reduce alcohol consumption. This study is the first to test multiple iterations of automatic action tendency retraining, followed by laboratory alcohol self-administration. METHODS: A total of 72 nontreatment-seeking, heavy drinking young adults ages 21 to 25 were randomized to automatic action tendency retraining or a control condition (i.e., "sham training"). Of these, 69 (54% male) completed 4 iterations of retraining or the control condition over 5 days with an alcohol drinking session on Day 5. Self-administration was conducted according to a human laboratory paradigm designed to model individual differences in impaired control (i.e., difficulty adhering to limits on alcohol consumption). RESULTS: Automatic action tendency retraining was not associated with greater reduction in alcohol approach tendency or less alcohol self-administration than the control condition. The laboratory paradigm was probably sufficiently sensitive to detect an effect of an experimental manipulation given the range of self-administration behavior observed, both in terms of number of alcoholic and nonalcoholic drinks and measures of drinking topography. CONCLUSIONS: Automatic action tendency retraining was ineffective among heavy drinking young adults without motivation to change their drinking. Details of the retraining procedure may have contributed to the lack of a significant effect. Despite null primary findings, the impaired control laboratory paradigm is a valid laboratory-based measure of young adult alcohol consumption that provides the opportunity to observe drinking topography and self-administration of nonalcoholic beverages (i.e., protective behavioral strategies directly related to alcohol use).

Tension Reduction Theory (Kushner et al., 1994) suggests alcohol is used as a means to alleviate negative affect (NA) such as shame and guilt. Shame is an internalized response in which blame is placed on the self, while guilt is not internalized and the blame is placed on the situation (Dearing et al., 2005). This study aims to investigate relationships of shame and guilt to alcohol use and problems through the mechanisms of multiple facets of impulsivity (i.e. UPPS) and impaired control over drinking (IC), which reflect behavioral control processes. The sample consisted of 419 college students (53% female). We examined direct and indirect relationships of shame and guilt on alcohol use and related problems through facets of impulsivity and IC. Shame and guilt were found to diverge (Woien et al., 2003). We found that those higher on shame-proneness used more alcohol and experienced more alcohol-related problems through increased negative urgency and IC. Conversely, guilt-prone individuals used less alcohol and experienced fewer alcohol-related problems through less negative urgency and IC. Our findings suggest that guilt is an adaptive form of negative affect, particularly when it comes to alcohol-related outcomes.
ABSTRACT
BACKGROUND: Cocaine and opioid co-use is a notable public health concern, but little is known about correlates of this behavior. Most prior findings come from treatment samples and concern cocaine and heroin. Findings from a nationally representative sample involving primarily prescription opioid misuse would expand knowledge. METHODS: Past-12-month cocaine and/or opioid users in Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) formed the sample (N = 839). Cocaine-only, opioid-only, and cocaine/opioid co-users were compared regarding sociodemographics, other substance involvement, psychiatric, and medical conditions/events. RESULTS: Opioid-only users were the largest group (n = 622), followed by cocaine-only (n = 144) and co-users (n = 73). The vast majority of opioid misuse was of prescription opioids (1.4% with past-12-month use of heroin). Notably, co-users did not differ from single drug users in frequency of use of either drug. Co-users did not have significantly greater incidence of any psychiatric conditions, medial conditions, or events. In preliminary analyses, co-users were more likely than either single use group to report several classes of other drug use. However, for most comparisons, opioid use did not add substantial risk beyond cocaine use. Differences on multiple sociodemographic variables suggested opioid-only users were at lowest risk of negative outcomes. These results may relate to a finding that opioid-only users were less likely to have sought treatment. CONCLUSIONS/IMPORTANCE: This sample of past-12-month cocaine and/or opioid users had greater involvement with other substances, more psychiatric and medical conditions compared to the general population. Co-users had greater involvement with other substances than opioid-only users in particular.

BACKGROUND: Although drinking for tension reduction has long been posited as a risk factor for alcohol-related problems, studies investigating anxiety in relation to risk for alcohol problems have returned inconsistent results, leading researchers to search for potential moderators. Negative urgency (the tendency to become behaviorally dysregulated when experiencing negative affect) is a potential moderator of theoretical interest because it may increase risk for alcohol problems among those high in negative affect. This study tested a cross-sectional mediated moderation hypothesis whereby an interactive effect of anxiety and negative urgency on alcohol problems is mediated through coping-related drinking motives. METHODS: The study utilized baseline data from a hazardously drinking sample of young adults (N = 193) evaluated for participation in a randomized controlled trial of naltrexone and motivational interviewing for drinking reduction. RESULTS: The direct effect of anxiety on physiological dependence symptoms was moderated by negative urgency such that the positive association between anxiety and physiological dependence symptoms became stronger as negative urgency increased. Indirect effects of anxiety and negative urgency on alcohol problems (operating through coping motives) were also observed. CONCLUSIONS: Although results of the current cross-sectional study require replication using longitudinal data, the findings suggest that the simultaneous presence of anxiety and negative urgency may be an important indicator of risk for alcohol use disorders via both direct interactive effects and indirect additive effects operating through coping motives. These findings have potentially important implications for prevention/intervention efforts for individuals who become disinhibited in the context of negative emotional states.

Impaired control, defined as "a breakdown of an intention to limit consumption" (Heather et al. J Stud Alcohol 1993; 54, 701), has historically been considered an important aspect of addiction. Despite recognition of its importance to addiction and potential value as an early indicator of problem drinking risk, we argue that impaired control over alcohol use has not received sufficient research attention. In an effort to spark further research, the present critical review offers brief discussion of the current state of knowledge regarding impaired control and avenues for future research. Three main research areas are addressed: (i) epidemiology; (ii) measurement issues; and (iii) potential mechanisms underlying relationships between impaired control and subsequent problem drinking. Measurement issues include complexities involved in self-report assessment of impaired control, development and validation of human and animal laboratory models, and impaired control's relationship to other constructs (i.e., impulsivity and other difficulties with self-control; symptoms of dependence such as craving). We discuss briefly 2 potential mechanisms that may help to explain why some drinkers experience impaired control while others do not: neurobiological dysfunction and family history/genetics. Suggestions for future research are focused on ways in which the impaired control construct may enhance prediction of who might be at particular risk of subsequent problem drinking and to facilitate intervention to reduce problem alcohol use.
