Background: The I3 Model posits that men are more likely to engage in sexual aggression (SA) when instigation (e.g., their masculinity is threatened) and impellance are high (e.g., high trait anger), and inhibition is low (e.g., alcohol intoxication). This study investigates the independent and interactive effects of trait anger and acute intoxica...

Gender-specific norms are learned, which can influence social norms, attitudes, and behaviors in specific situations. For example, men who conform to certain masculine norms/ideals may express their masculinity by drinking alcohol. Recent research examining the association between endorsement of alcohol-specific masculine norms and men’s risk for h...

Objective: Despite the commonly observed co-occurrence of obsessive–compulsive symptoms (OCS) and substance use in clinical populations, few researchers have examined potential mechanisms which contribute to this relationship. This study assessed the mediating role of drinking motives in the relationship between OCS, alcohol consumption, and its re...

Social anxiety symptoms may increase risk for heavy drinking and alcohol-related negative consequences during pregaming (drinking before a social event); efforts to identify malleable psychosocial risk factors are needed. This study examined cross-sectional relationships between social anxiety symptoms, pregaming behaviors, negative alcohol-related...

The goal of the current study is to examine the moderating role of public and altruistic prosocial behaviors on the associations between motivation/beliefs and alcohol use among college students. Data were collected as part of the Acculturation and Substance Use Research Team (ASURT) Study, and participants include 8040 college student drinkers (Ma...

Undergraduates with higher levels of social anxiety may be motivated to participate in high-risk drinking events (e.g., playing drinking games [DG]) as a way to “fit in” or facilitate socialization with peers), putting them at an elevated risk of experiencing alcohol-related negative consequences (e.g., blacking out). The present study sought to te...

Background: Many university students pregame or drink before a social event. Pregaming carries some risk due to its link to heavy drinking. During the COVID-19 pandemic, there was limited access to many drinking venues (e.g., bars/clubs). Moreover, universities shifted to a virtual format and imposed restrictions on in-person gatherings resulting i...

Background Negative urgency (NU), the tendency to act rashly during negative emotional states, is a robust risk factor for alcohol misuse that is posited to function in part through alcohol‐related cognitions. Nonetheless, relatively little research has examined mood‐based fluctuations in such cognitions, which could help to explain how the trait o...

Objective: A drinking game (DG) is a risky social drinking activity that is prevalent among university students and promotes rapid alcohol consumption. We examined university students' DG behaviors before and during the COVID-19 pandemic. Method: Students (N = 368; Mage=21.12; women = 72.6%; Hispanic = 44.7%) from seven universities completed an on...

Objective: Among college students, student-athletes are at increased risk for heavy alcohol consumption, participation in risky drinking practices (e.g., playing drinking games [DG]), and adverse alcohol-related consequences relative to non-student-athletes. Within the student-athlete population, level of sports participation (e.g., recreational o...

Background: Men's alcohol intoxication and perceptions of their masculinity as precarious (i.e., viewing masculinity as easily threatened) are independently related to men's perpetration of sexual aggression. Yet, the interactive effects of these constructs on sexual aggression are unclear. The goal of this study was to assess if precarious mascul...

Objective: Shame and guilt are often present prior to and consequent to alcohol use among college students. Little is known about the propensity to experience these emotions in the context of transgressions that occur while drinking alcohol. We examined the association between shame and guilt propensity for alcohol-related transgressions with hazar...

Limited qualitative research has been conducted to understand the experiences of victims of sexual harassment or assault (SHA) when a bystander intervenes. Even less research has focused on the consequences of bystander actions from the victim’s perspective, particularly regarding the aggressor’s subsequent behavior toward the victim and occurrence...

Alcohol intoxication may influence how bystanders interpret other people's consent and refusal cues. We examined the effects of alcohol intoxication on participants' perceptions of characters' consent and refusal indicators in a fictional vignette depicting an alcohol-involved sexual encounter. Young adults (n = 119, 52% women) participated in an a...

Using a cross-sectional survey study with undergraduate students ( N = 1257; M age = 20; 908 women) in the United States, this paper examined college students’ use of social media for coping and its association with COVID-19-related worries (loneliness, interpersonal stress, anxiety) and mental health outcomes (depression, generalized anxiety, and...

Objective: We examined the role of personal identity vis-à-vis COVID-related outcomes among college students from seven U.S. campuses during spring/summer 2021. Participants: The present sample consisted of 1,688 students (74.5% female, age range 18-29). The sample was ethnically diverse, and 57.3% were first-generation students. Procedures: Studen...

Explored the experiences of public university students (N = 1,573) in five domains (e.g., mental health, remote learning) during the first year of the COVID-19 pandemic, and whether these experiences differed as a function of college generation status. Mental health challenges were observed, with first-generation students reporting higher depressio...

Objective: A growing body of research implicates Fear of Missing Out (FoMO) as a risk factor for collegiate alcohol use. However, little research has explored the causal mechanisms of this association, which may depend on examining FoMO at both trait- and state-levels. We therefore examined how predispositions toward experiencing FoMO (i.e., trait...

Background The present study evaluated the two-factor structure of the Protective Behavioral Strategies for Marijuana Scale (PBSM-SF) Short-Form, a 13-item measure of harm reduction behaviors related to cannabis use. Additionally, the PBSM was evaluated for measurement invariance based on sex and state cannabis legalization status. Method Particip...

College students have shown elevated mental distress during the coronavirus disease of 2019 (COVID-19). The extent and persistence of mental distress as COVID-19 restrictions have continued is unclear. This study used latent profile analysis to identify student mental health risk subgroups and to evaluate subgroups in relation with substance use. A...

Prepartying, or drinking prior to going out, and playing drinking games (DG) can increase young adults' risk of heavy alcohol consumption. In the present study, we examined whether playing DG as a typical form of prepartying can increase alcohol consumption risk when compared with prepartying alone or with friends, and whether the type of DG played...

Background Alcohol intoxication is associated with significant negative social consequences. Social information processing theory provides a framework for understanding how the accurate decoding and interpretation of social cues are critical for effective social responding. Acute intoxication has the potential to disrupt facial emotion recognition....

Negative Urgency (NU) is a prominent risk factor for hazardous alcohol use. While research has helped elucidate how NU relates to neurobiological functioning with respect to alcohol use, no known work has contextualized such functioning within existing neurobiological theories in addiction. Therefore, we elucidated mechanisms contributing to the NU...

Negative Urgency (NU) is a prominent risk factor for hazardous alcohol use. While research has helped elucidate how NU relates to neurobiological functioning with respect to alcohol use, no known work has contextualized such functioning within existing neurobiological theories in addiction. Therefore, we elucidated mechanisms contributing to the NU...

Emerging adults are especially vulnerable to experiencing alcohol-related sexual assault. While bystanders play a critical role in preventing sexual assault, little is known about how bystander alcohol intoxication affects the intervention process—particularly in naturalistic settings. We recruited 315 emerging adult bargoers ages 21–29 (46% women;...

Alcohol's effects on bystander responses to potential sexual assault situations are understudied. In this mixed-methods study, we examined quality of bystander responses in intoxicated versus sober people. Participants were 121 young adults (ages 21–29, 50% female) randomly assigned to consume alcoholic beverages or soda water. After drinking, part...

Background Negative Urgency (NU), the tendency to act rashly during negative emotional states, is associated with alcohol misuse through various alcohol cognitions; however, these relationships are often examined in isolation and exclude certain alcohol cognitions. Objective: This study simultaneously modeled NU’s association with alcohol-related p...

Across two studies, we examined sexual assault history and bystander appraisals of risk and the moderating roles of danger cue salience (Study 1) and alcohol intoxication (Study 2) in women. Participants (Study 1 = 148, Study 2 = 64) read vignettes ending with cues of nonconsensual sexual activity and an opportunity to intervene. Participants also...

Caffeinated alcoholic beverage (CAB) consumption is a risky drinking practice for young people. The purpose of the current set of studies was to develop and psychometrically evaluate a theory-based CAB motives measure to understand what drives CAB consumption and its ensuing consequences. Using 4 different samples, we pilot tested the items of the...

Background: Moderating effects of alcohol outcome expectancies (AOE) on the social anxiety (SA)-alcohol misuse relationship are mixed. This may be explained by differential relationships between SA and context-specific AOE. Gender may further moderate these associations, as it influences SA, AOE, and drinking behaviors. Objectives: To examine the m...

Objective: High rates of alcohol-related sexual assault among young adults represent a significant public health problem. Bystander intervention programs are a promising strategy to reduce sexual assault incidence. However, little is known about how bystander intoxication may modify bystander intervention effectiveness. We examined the role of bys...

Alcohol intoxication, alcohol expectancies (AE), and alcohol valuations (AV) are associated with impaired risk detection for victims of sexual assault; these factors may also impair risk detection of bystanders in a potential sexual assault. However, the relationship between AE, AV, and alcohol intoxication on bystanders’ risk detection abilities h...

The Women's Issues in Behavior Therapy SIG is open to all ABCT members who are interested in women's issues. We are committed to increasing women's participation in all levels of conference activity and in ABCT governance, to increasing knowledge and awareness of women's health and mental health issues, and to providing opportunities for women of A...

Bystander interventions for sexual assault promote third-party interference. People who endorse rape myths blame victims more and perpetrators less; consequently, rape myth acceptance (RMA) can impede helping behaviors toward sexual assault victims. Acute alcohol intoxication may exacerbate the effects of RMA on bystander intervention. In this stud...

Purpose: Evidence suggests that people drink more alcohol and experience more adverse alcohol-related consequences (ARCs) on occasions when they also consume caffeine. The current study examined whether this increase in risk is a result of caffeine attenuating the subjective effects of alcohol intoxication (i.e., the masking hypothesis). Methods:...

Objective: Alcohol-related sexual violence remains a public health problem. Despite the popularity of sexual assault bystander intervention programs, these may be limited in addressing bystander intoxication because the effects of intoxication on intervening in a sexual assault are unknown. Therefore, we tested the effects of alcohol intoxication...

Alcohol outcome expectancies (i.e., expectancies) are important predictors of drinking that may vary according to drinking context. However, links between context-specific expectancies, drinking behavior, and hazardous alcohol use remain unexplored. To address this gap, we examined how context-specific expectancy subtypes were associated directly a...

Introduction: The relationship of social anxiety with alcohol use/problems has been examined among college student samples, but the relevance of findings to drinking game (DG) consumption/gaming consequences is not well understood due to a paucity of research. Methods: A cross-sectional sample of 224 Australian university students aged 18-25 yea...

Caffeine is the most widely available and consumed psychoactive substance in the United States. Extant work indicates that across substances, use expectancies play a marked role in the development and maintenance of consumption patterns. Despite a burgeoning line of etiological and intervention-oriented research focused on expectancies (e.g., alcoh...

Though alcohol use is a widespread behavior, men tend to drink more and experience more alcohol-related negative consequences than do women. Research suggests that individuals are motivated to maintain ingroup status by engaging in behaviors prototypical of the ingroup when group status has been threatened, and that men are particularly likely to d...

Alcohol-related sexual assault among young adult women continues to present a public health concern. Social information-processing theory provides an organizing framework for understanding how alcohol intoxication can impair the processing of sexual assault risk cues and behavioral responding in sexual assault scenarios. The aim of the present arti...

Background: Visual alcohol cues are often used to elicit craving (e.g., cue-reactivity), and selection of appropriate comparison cues is important to isolate the specific effect of craving for alcohol. Objectives: In the current study, via the development of a new set of non-alcoholic beverage cues, we examine measurement and methodological choi...

Objective: High rates of sexual victimization among college students necessitate further study of factors associated with sexual assault risk detection. The present study examined how social information processing relates to sexual assault risk detection as a function of sexual assault victimization history. Participants: 225 undergraduates (Mag...

Young people are increasingly consuming alcohol mixed with energy drinks (AmEDs). As coingestion of these beverages results in greater adverse consequences than from drinking alcohol alone, we need to understand what factors contribute to and deter coingestion. Existing studies in this area have not utilized a theoretically based or empirically val...

Alcohol use among adolescents is a public health concern; therefore, it is important that studies that examine factors associated with adolescent drinking behaviors utilize measures that are well-validated for use with this population. The current study examined the factor structure and convergent validity of the Brief Comprehensive Effects of Alco...

Background: Alcohol misuse has historically affected men more than women. However, the differences in drinking behaviors across sex have steadily decreased over time and accumulating research suggests that gender role orientation, or culturally scripted gender-specific characteristics, and negative reinforcement drinking motives may better explain...

In a controlled laboratory experiment, we study the causal effect of alcohol on economic decision making. A treatment group was given a dose of alcohol designed to target a blood alcohol concentration (BAC) of 0.08 while the BAC of those in the control group remained 0.00. We investigate the behavior of control and treatment groups in the following...

In this article, we describe several role-playing exercises on acculturation and relevant cultural adjustment processes that we incorporated into Tomcho and Foel’s classroom activity on acculturation, and we report data that examine subsequent changes in students’ responses on pretest and posttest measures shortly after the activity and present qua...

Background: Pregaming is a high-risk drinking behavior associated with increased alcohol consumption and alcohol-related problems. Quantity of alcohol consumed does not fully explain the level of problems associated with pregaming; yet, limited research has examined factors that may interact with pregaming behavior to contribute to the experience...

Drinking games and prepartying (i.e., drinking before going to a social gathering/event) have emerged as high-risk drinking behaviors in high school students. The present study examines the current prepartying behaviors of high school students who report current participation in extreme-consumption games (e.g., chugging) with those who do not. High...

Objective: Nonmedical prescription drug use, defined as using the drug without a prescription or in ways for which it is not prescribed, and traumatic event exposure are highly prevalent among college students. Despite evidence that posttraumatic stress symptoms could place college students at risk for nonmedical prescription drug problems, no stu...

Although research indicates that social anxiety (SA) is associated with problematic drinking, few studies have examined these relations among adolescents, and all alcohol-related assessments have been retrospective. Socially anxious youth may be at risk to drink in an effort to manage negative affectivity, and a proclivity towards disengagement cop...

This study proposes that posttraumatic stress symptomology and acculturative stress may further explain the relationship between family violence exposure and sexual risk-taking behaviors among Latino emerging adults (N = 1,100). A moderated mediation analysis indicated that lifetime rates of family violence exposure were positively associated with...

Prior person-centered research has consistently identified a subgroup of highly religious participants that uses significantly less alcohol when compared to the other subgroups. The construct of religious motivation is absent from existing examinations of the nuanced combinations of religiousness dimensions within persons, and alcohol expectancy va...

Research using alcohol-related visual stimuli has been limited due to a lack of published studies examining the psychometric properties of alcohol cues. The primary aim of the current study was to examine the factor structure, validity, and reliability of craving ratings following exposure to alcohol cues (including beer, wine, hard liquor, and mix...

Though social anxiety disorder and alcohol use disorders commonly co-occur, the mechanisms involved in social anxiety and hazardous drinking among college students are not well understood. The current study contributes to the emerging literature on social anxiety and college drinking as the first known study to test how positive (e.g. “I would feel...

Prior person-centered research has consistently identified a subgroup of highly religious participants that uses significantly less alcohol when compared to the other subgroups. The construct of religious motivation is absent from existing examinations of the nuanced combinations of religiousness dimensions within persons, and alcohol expectancy va...

Cigarette smoking is one of the leading causes of disease and death in the United States, and smoking typically begins in adolescence. It is therefore important to understand factors that relate to increased risk for cigarette smoking during this stage of development. Adolescence is a period when emotion regulatory capacities are still emerging and...

Objective: This cross-sectional study was conducted to investigate which components of acculturation relate to drinking games participation among Hispanic college students. We also sought to examine whether the relationships between acculturation and drinking games would differ from the associations between acculturation and other alcohol-related...

Background: Drinking game participation has been associated with increased frequency and quantity of alcohol use, as well as alcohol-related problems, in college students. To date, the assessment of drinking games typically entails the use of self-developed measures of frequency of participation and amount of alcohol consumed while playing. Objec...

Drinking games are a high-risk social drinking activity consisting of rules and guidelines that determine when and how much to drink (Polizzotto et al., 2007). Borsari's (2004) seminal review paper on drinking games in the college environment succinctly captured the published literature as of February 2004. However, research on college drinking gam...

Previous research on culture and emotion regulation has focused primarily on comparing participants from individualistic and collectivistic backgrounds (e.g., European Americans vs. Asians/Asian Americans). However, ethnic groups that are equally individualistic or collectivistic can still vary notably in cultural norms and practices regarding emot...

Objective: This cross-sectional study was conducted to investigate which components of acculturation relate to drinking games participation among Hispanic college students. We also sought to examine whether the relationships between acculturation and drinking games would differ from the associations between acculturation and other alcohol-related o...

Early age of onset of alcohol use or prescription drug misuse (PDM) is associated with later alcohol or prescription drug-related substance use disorders. While the prevalence of PDM among youth continues to increase at an alarming rate, relatively little research attention has been given to the study of adolescent PDM. The present study examined d...

Prepartying (i.e. drinking before a social event/gathering) and participation in drinking games are two high-risk drinking behaviors practiced by adolescents. Engaging in both these drinking behaviors may contribute to a multiple risk paradigm, wherein the risk associated with one’s general drinking is combined with the additional risk of rapidly i...

To further elucidate how individual differences in the frequency with which people get upset about having negative emotions (i.e., meta-emotions) and how often they experience negative emotions (i.e., trait emotions) are related to drinking to cope, we tested direct and mediated path models predicting drinking to cope in a sample of emerging adult...

Abstract Drinking games are widespread on college campuses and pose health risks to their players. Although there has been considerable research progress in the college drinking games literature, there does not appear to be a standard definition of the term "drinking games." Researchers, however, have attempted to classify and categorize drinking g...

The current study examined a conditional indirect effects model of the association between religiousness and adolescents' hazardous alcohol use. In doing so, we responded to the need to include both mediators and moderators, and the need for theoretically informed models when examining religiousness and adolescents' alcohol use. The sample consiste...

The present study used a cultural and social cognitive conceptual framework to investigate whether alcohol expectancies and valuations would mediate the associations between specific acculturation orientations and alcohol-related risk behaviors. The sample comprised 1,527 Hispanic students attending colleges and universities in diverse regions of t...

Objectives: This study examined the measurement equivalence of the Brief Comprehensive Effects of Alcohol scale (B-CEOA; Ham et al., 2005)--a measure that assesses alcohol outcome expectancies (AOE) and expectancy evaluations-across ethnic groups and genders among multiethnic college student samples. Method: Undergraduates provided self-report d...

Objectives: To examine how legal age status, gender, and self-reported reasons for pregaming are linked to pregaming for two common drinking contexts: a bar and a Greek party. Method: Participants who reported pregaming at least once a month (n = 2888 students aged 18-25 years) were recruited from 30 colleges/universities across the United State...

Objectives: The current study evaluated the mediational role of well-being in the relationship between identity development and psychosocial functioning. Method: A sample of 7,649 undergraduate students (73% female; mean age = 19.95, standard deviation = 1.98; 62% Caucasian) completed measures of personal identity, well-being, internalizing symp...

This chapter aims to provide a background in anxiety disorder/substance use disorder (SUD) comorbidity and its treatment, with an in-depth focus on social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD). The chapter covers relevant comorbidity models and describes the complexities of these comorbid conditions, followed by a section...

Sensation seeking is a known risk factor for unsafe and reckless behavior among college students, but its association with well-being is unknown. Given that exploration plays an important psychosocial role during the transition to adulthood, we examined the possibility that sensation seeking is also associated with psychological well-being. In a la...

The typically positive relationship between cognitive reappraisal and psychological functioning may be nullified for Latinos embedded within multiple contexts of oppression (Perez & Soto, 2011). Multiply oppressive contexts are characterized by exposure to oppression at a societal level (distal oppression), in the immediate environment (proximal op...

Although alcohol use varies across settings, current measures of alcohol outcome expectancies (i.e., perceived likelihood of experiencing a drinking outcome; AOE) and valuations (i.e., desirability of specific drinking outcomes) do not specify the drinking context explicitly. Therefore, the contextual factors (which may affect both AOE and valuatio...

Alcohol use among adolescents is a health-risk behavior that can result in serious consequences. Furthermore, adolescents participate in drinking games—a risky drinking behavior designed to facilitate heavy alcohol consumption in a short period of time. Both alcohol expectancies and drinking motives have been identified as robust correlates of alco...

Research suggests that high school students who participate in sports may be at elevated risk for alcohol use compared to their non-athlete peers; however, reasons for this association are unclear. Alcohol expectancy theory posits that individuals who expect favorable outcomes to occur because of alcohol use are more likely to drink than those who...

Purpose: To examine the associations of alcohol expectancy outcomes and valuations with intention to use. Method: A total of 157 adolescent nonusers completed anonymous self-report surveys. Results: Adolescents who perceived more access to alcohol, expected less negative and more positive drinking outcomes, and evaluated positive outcomes favo...

According to the Stress Response Dampening model, problem drinking develops after learning that alcohol limits the stress response in anxiety-provoking situations. However, laboratory-based studies testing alcohol's effects on social anxiety have yielded mixed results. The current study was the first to examine stress response dampening across two...

Pregaming is the practice of consuming alcohol prior to going out to a social event. Although pregaming has begun to receive research attention in the college setting, very little is known about this risky drinking behavior in high school students. As pregaming has health implications for both students who are college bound and those who are not, w...

Although past studies have revealed ethnic and cultural variations in social anxiety, little research addresses why these variations might arise. The present study addressed this gap by examining emotion regulation as an explanatory mechanism that may account for such differences. Drawing from a culture-specific (Kitayama, Karasawa, & Mesquita, 200...

Research has shown that college student-athletes are at increased risk for hazardous alcohol use. As such, this study examined social and cognitive influences on athletes’ alcohol consumption by exploring the association between injunctive norms (parental, teammate, and coach approval) and hazardous alcohol use among college athletes, and testing w...

According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ec...

Alcohol outcome expectancies (AOE), or beliefs about the effects of drinking, are believed to moderate the association between social anxiety and hazardous alcohol use. AOE can also vary depending on the drinking context. The current study tested whether AOE specific to three drinking contexts would moderate the association between social anxiety a...

Alcohol typically has a detrimental impact on memory across a variety of encoding and retrieval conditions (e.g., Mintzer, 2007; Ray & Bates, 2006). No research has addressed alcohol's effect on memory for lengthy and interactive events and little has tested alcohol's effect on free recall. In this study 94 participants were randomly assigned to al...

Although binge drinking is commonly defined as the consumption of at least 5 drinks in 1 sitting for men and 4 for women, the Alcohol Use Disorders Identification Test (AUDIT) defines binge drinking as the consumption of 6 or more drinks in 1 sitting for both men and women. This study examined the effect of using gender-specific binge drinking defi...

The present study investigated the associations of well-being with engagement in illicit drug use, sexual risk taking, and impaired driving in a sample of 9,515 students from 30 U.S. colleges and universities. Participants completed measures of subjective well-being, psychological well-being, and eudaimonic well-being, and indicated how many times...

In the present study, we examined a bidimensional model of acculturation (which includes both heritage and U.S. practices, values, and identifications) in relation to hazardous alcohol use, illicit drug use, unsafe sexual behavior, and impaired driving. A sample of 3,251 first- and second-generation immigrant students from 30 U.S. colleges and univ...
