RESUMO

Background: College students continue to report problematic alcohol use. To mitigate adverse outcomes, recent studies have employed harm reduction strategies known as Protective Behavioral Strategies (PBS). Deviance Regulation Theory (DRT), an impression management intervention, has been used to promote the use of PBS. DRT relies on impression management to modify behavior. This may be especially important for individuals with higher levels of trait narcissism. Method: College student drinkers (n = 132) were randomly assigned to receive a positive message about PBS users, a negative message about non-PBS users, or control. Participants reported on current PBS use norms, daily alcohol use, PBS use, and any alcohol-related problems experienced during the previous week for the next 10 weeks. Results: Data were analyzed using multilevel regression to examine PBS use across time by condition. When PBS norms were low, narcissism was strongly associated with lower rates of PBS use in the control group. If individuals received a positive or negative message, the association between narcissism and PBS use was diminished, among individuals with low PBS norms. There were no significant differences at mean or high levels of norms, indicating the messaging was only important for the highest risk group (i.e., those with low PBS norms). Discussion: The results of this study suggest that message framing may be effective at reducing the robust negative association between narcissism and PBS use for individuals with low PBS norms. Positive messages about individuals that use PBS may be one approach to mitigating problematic alcohol consumption in this at-risk group.

RESUMO

OBJECTIVES: Hispanic/Latinx drinkers have been found to experience more adverse alcohol-related consequences than any other racial/ethnic group. Due to this, researchers have looked at the connection between drinking and cultural factors, alongside discrimination, to further analyze what sociocultural factors lead to negative outcomes when drinking. DESIGN: Researchers used a sample of Hispanic/Latinx young adult drinkers (n = 710) with an average age of 22.43 (SD = 6.69), recruited through social media and assessed on several factors, including protective behavioral strategies (PBS), alcohol use severity, bicultural self-efficacy, discrimination, acculturation, and enculturation. RESULTS: Utilizing an observed variable path analysis, results showed perceived discrimination to have a significant effect on all variables in the model (bicultural self-efficacy, acculturation, enculturation, PBS self-efficacy, PBS use, and alcohol use severity). Acculturation was positively associated with PBS self-efficacy, while enculturation was positively associated with PBS use. PBS self-efficacy was positively correlated with PBS use and negatively associated with alcohol use severity. There was a significant total indirect effect from perceived discrimination to alcohol use severity through various paths (i.e. PBS self-efficacy, acculturation, and bicultural self-efficacy), with the strongest path to occur through PBS self-efficacy. CONCLUSIONS: Findings showcase the risk and protective effects of various sociocultural factors on drinking behaviors among young adults. PBS self-efficacy was found to have robust protective effects against alcohol use severity. Future research should continue to investigate these sociocultural and behavioral factors in order to develop efforts to mitigate hazardous alcohol use among Hispanic/Latinx young adult drinkers.

RESUMO

Alcohol protective behavioral strategies (PBS) are commonly conceptualized with a three-factor model, as used in the Protective Behavioral Strategies Scale-20 (PBSS-20). However, inconsistencies exist between factors and drinking outcomes. The current study used factor analysis to test a two-factor structure directly via controlled consumption (Direct/CC) and indirectly via harm reduction (Indirect/HR) using the PBSS-20 among a combined sample of n = 4,883 drinkers. Both the two- and three-factor structures evince similar model fit. A two-factor model yielded more concise PBS measurement. Negative associations were observed with consumption (Direct/CC PBS) and problems (Indirect/HR). A condensed, eight-item, two-factor model accounted for less variance in alcohol consumption, however more variance in alcohol-related problems. A more consistent framework for understanding the impact of PBS on alcohol-related outcomes is provided.

RESUMO

ObjectiveAdverse sexual experiences (ASE), including sexual violence, sexual risk behaviors, and regretted sex, are highly prevalent among sexual and gender minorities (SGM) compared to cisgender and heterosexual individuals. Research indicates ASEs are associated with increased mental health symptomatology and decreased subsequent protective behavior use. The Sexual and Negative Dating Inventory (SANDI) measures dating and sexual protective strategies and includes five factors: Location Sharing, Assertiveness, Self-Protection, Risk Reduction and Privacy. SANDI total scores are linked to lower ASEs in heteronormative samples. Method: SANDI was previously validated in a sample of n = 1,289 college students. Data were examined from n = 313 (24.28%) SGM individuals at baseline, and n = 95 at one-month follow-up. Individuals were 19.70 (2.98 SD) years old, and 25% were non-white. Model fit was adequate for SGM: χ2(484) = 1729.621, p < .001, CFI = .947, RMSEA = .063 (90% CI = .060, .066), SRMR = .048. Results: Non-cisgender men and non-heterosexual individuals endorse using more of the SANDI at the factor level. Using logistic regression, SANDI was not associated with history of sexual violence or sexual violence over the next month. SANDI is inversely associated with history of sexual risk and prospectively associated with less sexual risk over the next month. Negative binomial regression analyses showed SANDI was not associated with a history of regretted sex; however, SANDI was moderately associated with decreased regretted sex over the next month. Conclusion: Findings highlight the importance of dating and sexual protective behaviors across dimensions of gender and sexual orientation.

RESUMO

Altered reward processing has been implicated in the onset and maintenance of binge-eating disorder (BED). However, it is unclear which precise neurocognitive reward processes may contribute to BED. In the present study, 40 individuals with BED and 40 age-, sex-, and BMI-matched controls completed a reward (incentive delay) task while their neural activity was recorded using electroencephalography (EEG). Individuals with BED also completed a 10-day ecological momentary assessment (EMA) protocol assessing binge-eating behavior in the natural environment. Event-related potential (ERP) analysis of the EEG indicated that individuals with BED had stronger anticipatory (CNV) and outcome-related (RewP) neural reward activity to food and monetary rewards, compared to controls. However, within the BED group, greater frequency of binge eating during the EMA protocol was associated with stronger anticipatory (CNV) but weaker outcome-related (RewP) neural reward activity. These associations within the BED group were unique to food, and not monetary, rewards. Although preliminary, these results suggest that both anticipatory ("wanting") and outcome ("liking") reward processes may be generally amplified in BED. However, they also suggest that among individuals with BED, disorder severity may be associated with increased anticipatory reward processes ("wanting"), but relatively decreased reward-outcome processing ("liking"), of food rewards specifically.

RESUMO

The incentive-sensitization theory (IST) has emerged as a potentially useful theory in explaining substance addiction. IST postulates that the prolonged use of a substance can alter neural systems that are often involved in incentive motivation and reward processes, leading to an increased "sensitization" to the substance and associated stimuli. However, this increased sensitization is thought to mediate only the individual's craving of the substance (e.g., their "wanting"), not their enjoyment of the substance (e.g., their "liking"), a process that may involve unconscious implicit changes in cognitive networks linked to specific substances. Consequently, IST may better explain the real-world dissonance reported for individuals who want to accomplish long-term substance cessation but fail to do so, a phenomenon that is common in adolescent smokers. Thus, the present study aimed to examine the principles of IST in a sample of 154 adolescent ad libitum smokers (Mage = 16.57, SDage = 1.12, 61.14% male) utilizing ecological momentary assessment. Data were analyzed utilizing a multilevel structural equation model examining changes in positive affect (PA), negative affect (NA), and stress from Time 1 (T1) and Time 2 (T2) as a function of smoking and tested the influence of implicit cognition (specifically, implicit attitudes about smoking [Implicit Association Test (IAT)]) on these associations. Consistent with the principles of IST, results found a modest significant negative association between smoking status at T1 and PA at T2 (B = -0.11, p = .047). This association was further moderated by IAT (B = -0.19, p = .029) and was particularly potentiated at high levels of IAT (B = -0.44, p < .001), compared to low (B = -0.05, p = .663) or mean levels of IAT (B = -0.25, p = .004). Findings from this study provide additional support to the principles underlying IST and indicate that, in adolescents, smoking may result in thwarted PA indicative of a transition from "liking" toward "wanting," and this is especially pronounced among those with stronger implicit smoking cognitions.

RESUMO

ObjectiveCollege students consume more alcohol and engage in binge drinking more frequently than their non-college attending peers, and prevalence of alcohol-related consequences (e.g., drinking and driving; taking avoidable risks) has not decreased proportionally with decreases in consumption. Social anxiety and alcohol expectancies, or beliefs about the effects of alcohol, have been found to be significantly related to alcohol use and account for significant variance in alcohol use and related consequences. Few studies, however, have examined how other social variables such as need to belong and social connectedness may fit into existing models of increased and risky alcohol use. Methods: Students at a large state university (n = 1,278) completed an online survey measuring alcohol expectancies, need to belong, social anxiety, and social connectedness. Mean age of participants was 19.65 years, and 59.5% self-identified as female, 39.8% male, and 0.7% identified as transgender. Structural equation modeling supported hypothesized relationships between need to belong, social anxiety, social connectedness, alcohol expectancies, and alcohol use, a mean centered variable that included binge drinking, drinking frequency, and amount of consumption. Results: Positive alcohol expectancies related to tension reduction, sociability, and sexuality, were positively related to drinking, such that increased alcohol expectancies were associated with increased drinking. Alcohol expectancies mediated the relationship between need to belong and increased alcohol use, as well as social connectedness and increased alcohol use. Similarly, social anxiety also mediated these relationships. No direct relationships were found between need to belong or social connectedness and alcohol use, suggesting previous research exploring these relationships may have excluded control variables (e.g., biological sex, race/ethnicity) that better explain the impact of need to belong and social connectedness on alcohol use. Conclusion: Prevention and intervention efforts might be more effective in reducing alcohol use if social factors are more broadly targeted.

RESUMO

Objective: Suicidal ideation (SI) is highly prevalent among college students. Research has shown that college students are also more likely to experience low distress tolerance, affect lability, and experiential avoidance, which have been linked to SI. There is a critical need to examine the mechanisms that increase the risk of SI among college students. It is hypothesized that distress tolerance will be a strong predictor of SI, and affect lability as well as experiential avoidance will mediate this relationship. Participants and Methods: Participants (n = 820) from a Southeastern University completed an online survey, inquiring about demographic information, affect lability, SI, experiential avoidance, and distress tolerance. Data were analyzed utilizing structural equation modeling. Results: Distress tolerance was not directly related to SI. However, affect lability and experiential avoidance were found to mediate this relationship. Conclusions: Affect lability and experiential avoidance may be important predictors of SI among college students.

RESUMO

OBJECTIVE: The goal of the current study was to better understand affect-drinking relations among those diagnosed with an alcohol use disorder (AUD), as recent meta-analytic work suggests that daily negative affect may not universally predict subsequent alcohol consumption in those nondependent on alcohol. Specifically, we investigated the between- and within-person effects of positive and negative affects on drinking. METHOD: Participants (n = 92) who met AUD diagnostic criteria completed a 90-day daily assessment of drinking behavior and positive and negative affects. RESULTS: Time-lagged multilevel modeling revealed that within-person elevations in negative affect predicted increased odds and quantity of drinking later in the day. Relations between positive affect and drinking were nonsignificant. CONCLUSIONS: These findings are in contrast to recent meta-analytic findings and highlight the complexity of affect-drinking relations among those diagnosed with AUD.

RESUMO

The COVID-19 pandemic resulted in global monumental upheaval. Many people were displaced from their jobs and sources of income. COVID-19 was also linked to increased mental health difficulties and increased alcohol consumption and problems. The current study aims to identify the indirect effect of depression, stress, and anxiety on the relations between the economic burden of COVID-19 and alcohol problems. Participants (N = 344) were recruited via Amazon's Mechanical Turk (MTurk). Participants completed a questionnaire about substance use, mood, and the economic burden of COVID-19. Eligible participants were 18 years or older, consumed alcohol or cannabis within the past week, and verified through Amazon. Results indicated significant indirect effects of depression, stress, and anxiety on the association between the economic burden of COVID-19 and alcohol problems regardless of use. Findings revealed large effect sizes, suggesting that mental health symptomatology may have a large impact on the association between COVID-19's economic burden and alcohol-related problems. Findings suggest mental health difficulties indirectly effect the association between COVID-19's economic burden and alcohol-related problems. Intervention efforts targeting mental health may be beneficial in reducing alcohol problems among individuals experiencing distress due to large-scale public health impact, such as the COVID-19 pandemic.

RESUMO

Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess affect and the number of alcoholic drinks consumed. Results indicate that people are not more likely to drink on days they experience high negative affect, but are more likely to drink and drink heavily on days high in positive affect. People self-reporting a motivational tendency to drink-to-cope and drink-to-enhance consumed more alcohol, but not on days they experienced higher negative and positive affect. Results were robust across different operationalizations of affect, study designs, study populations, and individual characteristics. These findings challenge the long-held belief that people drink more alcohol following increases in negative affect. Integrating these findings under different theoretical models and limitations of this field of research, we collectively propose an agenda for future research to explore open questions surrounding affect and alcohol use.

RESUMO

Cannabis is increasingly accessible and use is increasing rapidly among older adults as laws change and cannabis becomes more frequently prescribed in healthcare settings. Past research identified cognitive effects of cannabis use among adolescents and young adults that can persist for several weeks after intoxication, though little is known about how these effects generalize to older adults. Participants (N = 1348) were drawn from the Health and Retirement Study (HRS) and were categorized as current occasional users (up to once/week in the past year, n = 36), current frequent users (once per week or more in the past year, n = 92), past users (n = 334), and non-users (n = 886). Participant ages ranged from 50 to 98 (M = 67.25, SD = 10.68). Uncontrolled, one-way ANOVAs and controlled ANCOVAs were used to examine between-group differences on immediate and delayed wordlist memory and working memory (serial sevens). When controlling for age, gender, education, and minority status, current frequent users demonstrated significantly worse immediate memory performance compared to past and non-users. However, this difference could have been the result of acute, residual effects of past-month cannabis use among current users. In controlled analyses, there were no differences between groups on delayed or working memory. Findings indicate that greater than weekly cannabis use may result in attentional and short-term memory deficits. Further, these effects may be mitigated by sustained abstinence. Limitations including sample size and measures of cannabis use warrant future studies to replicate and build upon these findings.

RESUMO

Affect regulation models hypothesize that aversive affective states drive binge-eating behavior, which serves to regulate unpleasant emotions. Research using ecological momentary assessment (EMA) demonstrates that increases in guilt most strongly predict subsequent binge-eating episodes, raising the question: why would individuals with binge-eating pathology engage in a binge-eating episode when they feel guilty? Food craving is a robust predictor of binge eating and is commonly associated with subsequent feelings of guilt. The current study used EMA to test the hypothesis that food craving may promote increased feelings of guilt, which then predict an increased risk of binge eating within a sample of 109 individuals with binge-eating disorder. Multilevel mediation models indicated that increased momentary craving at Time 1 directly predicted a greater likelihood of binge eating at Time 2, and craving also indirectly predicted binge eating at Time 2 through momentary increases in guilt at Time 2. In other words, experiencing food craving at one time point was related to an increased likelihood of binge eating at the next time point, and a portion of this influence was attributable to increasing feelings of guilt. These results challenge simple affect regulation models of binge eating, suggesting that food-related anticipatory reward processes (i.e., craving) may be the primary driver of binge-eating risk and account for the increases in guilt commonly observed prior to binge-eating episodes. Although experimental studies are needed to confirm this possibility, these results suggest the importance of addressing food cravings within interventions for binge-eating disorder.

RESUMO

Background: Despite modest reductions in alcohol use among college students, drinking-related harms continue to be prevalent. Group-delivered programs have had little impact on drinking except for experiential expectancy challenge interventions that are impractical because they rely on alcohol administration. Expectancy Challenge Alcohol Literacy Curriculum (ECALC), however, offers a non-experiential alternative suitable for widespread implementation for universal, selective, or indicated prevention. Objectives: ECALC has been effective with mandated students, fraternity members, and small classes of 30 or fewer first-year college students. Larger universities, however, typically have classes with 100 students or more, and ECALC has not yet been tested with groups of this size. To fill this gap, we conducted a group randomized trial in which five class sections with over 100 college students received either ECALC or an attention-matched control presentation and completed follow-up at four weeks. Results: ECALC was associated with significant changes on six subscales of the Comprehensive Effects of Alcohol Scale (CEOA), post-intervention expectancies predicted drinking at four-week follow-up, and there were significant expectancy differences between groups. Compared to the control group, students who received ECALC demonstrated significant expectancy changes and reported less alcohol use at follow-up. Conclusions: Findings suggest ECALC is an effective, single session group-delivered intervention program that can be successfully implemented in large classes.

RESUMO

Loss-of-control eating (LOCE) is highly prevalent in college students and may be driven by enduring personality traits. Narcissism is often conceptualized with two broad domains: grandiose and vulnerable. The association between narcissism and LOCE has not been directly assessed, nor the potential influence of emotion regulation deficits, which are differentially associated with grandiosity and vulnerability. This study hypothesized an association between vulnerable narcissism and LOCE in college students by way of emotion regulation difficulties, extending prior findings. Participants (n = 704) completed a survey on pathological eating and body image disturbance, emotion regulation difficulties, and narcissistic traits. Results supported a full mediation effect, such that vulnerable narcissism was positively associated with LOCE by way of emotion regulation difficulties. Present findings suggest the mechanism primarily predictive of LOCE is emotion regulation difficulties, and predisposition to deficits in emotion regulation associated with vulnerable narcissism may increase the odds of LOCE. Additionally, it was noted that grandiose narcissism evinced a fully mediated inverse association with LOCE. Clinical implications and directions for future research are discussed.

RESUMO

Recent research shows a link between identity and behavior change. Despite the existence of several measures that assess components of drinking identity, no measures examine the idiosyncrasies of a "Responsible Drinking Identity," though responsible drinking is an aim of many alcohol-related interventions. The present study created a measure of responsible drinking identity, the Personal Assessment of Responsible Drinking Identity (PARDI). Two cross-sectional designs and a prospective follow-up were used to develop and assess the psychometric properties of the PARDI. Study 1 used a U.S. national sample of college students who endorsed alcohol use (n = 911) to conduct an Exploratory Factor Analysis. Study 2 consisted of college students from a Southeastern University (n = 1,096) and was used to conduct a Confirmatory Factor Analysis, as well as evaluate convergent, discriminant, concurrent, and incremental validity. A subsample from Study 2 was then assessed after 1 month (n = 194). The follow-up examined test-retest reliability and predictive validity. The PARDI consists of four identity-based factors that are indicative of responsible drinking. The measure had adequate validity across all domains and good test-retest reliability. The measure appears to predict future protective behaviorial strategies (safe drinking behaviors), which mediates the relationship between the PARDI and both future alcohol use and consequences, suggesting safe or responsible drinking identity may drive a key behavioral target of substance use interventions. The PARDI may offer a tool to aid in quantifying underlying constructs of identity and behavior change in substance use interventions. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

Reward-related processes are an increasing focus of eating disorders research. Although evidence suggests that numerous distinct reward processes may contribute to eating pathology (e.g., reward learning and delay discounting), existing etiological models of reward dysfunction tend to focus on only a limited number of reward processes, and frequently lack specificity when identifying the individual reward processes hypothesized to contribute to dysregulated eating behavior. Moreover, existing theories have been limited in their integration of reward-related processes with other demonstrated risk and maintenance factors for eating disorders (e.g., affect and cognition), potentially contributing to underdeveloped models of eating pathology. In this article, we highlight five distinct reward processes with theorized or demonstrated relevance to eating disorders involving binge-eating, followed by a review of two well-established risk/maintenance factors for binge-eating pathology. We then introduce two novel models of binge eating onset and maintenance that integrate these factors (i.e., the Affect, Reward, Cognition models), and discuss methods for testing each of the models in future research. Ultimately, we hope that the proposed models provide a springboard for the continued evolution of more precise and comprehensive theories of reward dysfunction in the eating disorders, as well as the development of novel intervention approaches. PUBLIC SIGNIFICANCE STATEMENT: Eating disorders are associated with abnormalities in multiple domains of reward functioning. However, models of reward dysfunction within the eating disorders have not been well-integrated with prominent models of affect and cognition. This article presents two novel models of onset and maintenance for binge-eating pathology, which attempt to integrate observed reward abnormalities with other affective and cognitive processes implicated in binge-type eating disorders.

RESUMO

The prevalence of eating pathology among college students has increased significantly in recent years. This coincides with increases in the use of cannabis, both nationally, but also among college students. Problematic cannabis use has been linked to eating pathology in prior research. Research also shows that cannabis may affect appetitive drives linked to food consumption. The current study tested the hypothesis that the association between problem cannabis use and eating pathology was mediated by greater loss of control eating. Cross-sectional data were collected from a sample of 805 college student cannabis users at a large Southeastern university in the U.S. The sample were primarily Caucasian (76%) and female (65.22%) with an average age of 20.15 (SD = 3.91). Participants completed surveys assessing eating outcomes (loss of control eating and eating pathology), cannabis use, and cannabis-related problems. The analysis used an observed variable path model. After controlling for cannabis use, cannabis-related problems were indirectly linked to eating pathology via loss of control eating (B = 0.109, SE = 0.025, p < .001), supporting the primary hypothesis. The direct relationship between cannabis-related problems and eating pathology was fully accounted for (B = 0.010, SE = 0.028, p = .724) by the indirect effect of loss of control eating. These data suggest that the association between problematic forms of cannabis use and eating pathology may be due to the association between cannabis problems and loss of control eating. While this may be due to changes in appetite and food evaluation as a function of more problematic use patterns, it may also be that individuals with problematic cannabis use have more problematic eating patterns due to deficits in adaptive coping strategies. Future research should seek to parse out these different potential explanations.

RESUMO

Background: Discrimination is a pervasive societal issue that monumentally impacts people of color (POC). Many Black, Asian, and Hispanic/Latinx individuals report experiencing race-based discrimination in their lifetime. Discrimination has previously been linked to adverse health outcomes among POC, including stress, depressive, and posttraumatic stress disorder symptoms. These health disparities are posited to have become exacerbated by COVID-19 and the racial awakening of 2020. The current study examined the short- and long-term effects of discrimination on stress, depression, and oppression-based trauma among POC. Methods: Participants were (n = 398) who identified as Black, Indigenous, Hispanic/Latinx, and Asian completed an online self-report survey assessing discrimination, depression, stress, and oppression-based trauma collected at 3 time points: (T1) beginning of the COVID-19 pandemic (May 2020), (T2) 6 weeks later during the racial awakening of 2020 (June 2020), (T3) one year later (June 2021). Results: Significant positive paths were revealed from T1 discrimination to T2 depression, T2 stress, and T3 oppression-based trauma. The association between T1 discrimination and T3 oppression-based trauma was partially mediated by T2 depression, but not by stress; total and total indirect effects remained significant. The final model accounted for a significant proportion of the variance in T3 oppression-based trauma, T2 depression, and T2 stress. Conclusion: Findings are consistent with prior research linking discriminatory experiences with mental health symptomatology and provide evidence that race-based discrimination poses harmful short-and long-term mental health consequences. Further research is necessary to better understand oppression-based trauma to improve the accuracy of clinical diagnosis and treatment of POC.

RESUMO

Objective: Alcohol use continues to be prevalent and problematic among young adult samples. Protective behavioral strategies (PBS), which are harm reduction strategies utilized while drinking, have been linked to decreased alcohol use and subsequent alcohol-related problems. An individual's likelihood of adopting PBS and other health behaviors, according to The Health Belief Model (HBM), is dependent on perceived susceptibility to and severity of adverse health outcomes, as well as perceived benefits and barriers related to implementing those behaviors. The present study examined whether the perceived effectiveness of PBS in the context of the HBM leads to an increase in PBS use. Method: The analytic sample (n =694 college students, Mage =20.21, SD =4.37, 63.26% female, 72.05% Caucasian) self-reported demographics, weekly alcohol consumption (i.e., frequency, intensity, and quantity), alcohol-related problems, use of PBS, and perceived effectiveness of PBS use. A latent variable model was used to test the effect of perceived PBS effectiveness on PBS use, alcohol consumption, and alcohol-related problems. Results: Perceived PBS effectiveness was associated with a higher likelihood of using PBS subtypes (Manner of Drinking, Stopping/Limiting Drinking, and Serious Harm Reduction), which in turn was associated with reductions in alcohol consumption and problems. Conclusions: These findings suggest that increasing perceptions of PBS effectiveness may lead to more PBS use, decreased alcohol consumption, and fewer alcohol-related problems. Future research could implement longitudinal methodology to assess attempts to increase perceived effectiveness of PBS use and potentially establish a causal link between these perceptions, PBS use, and alcohol-related outcomes.
