Impulsivity, sex-related alcohol expectancies, alcohol use, and sexual risk-taking among bisexual women.

BACKGROUND AND OBJECTIVES: According to the acquired preparedness model, personality traits, such as impulsivity, may influence the learning process, contributing to heightened expectations surrounding risky behaviors (i.e., alcohol use, sexual risk-taking). As bisexual women demonstrate heightened risk for hazardous alcohol- and sex-related behaviors, the present study examined a sequential pathway, whereby the relation between impulsivity and sexual risk-taking is mediated through sex-related alcohol expectancies and alcohol use. METHODS: Data were collected from 225 self-identified cisgender, bisexual women between the ages of 18 and 30 years (M = 22.77, SD = 3.45), who participated in an online survey. Participants reported on impulsivity, sex-related alcohol expectancies, alcohol use, and experiences of sexual risk-taking. RESULTS: Results revealed that sex-related alcohol expectancies and alcohol use sequentially mediated the relation between impulsivity and sexual risk-taking. Thus, greater impulsivity was related to greater sexual risk-taking through heightened sex-related alcohol expectancies and elevated alcohol use. DISCUSSION AND CONCLUSIONS: Findings from this study highlight mechanisms associated with risky drinking and sexual behaviors among this at-risk population. Such information could aid the development of more efficacious prevention and intervention programs aimed at reducing consequences associated with alcohol use and sexual risk-taking among bisexual women. SCIENTIFIC SIGNIFICANCE: Bisexual women are at heightened risk for alcohol-related problems, including sexual risk-taking. Findings from the current study identify impulsivity and sex-related alcohol expectancies as independent and integrative predictors of such risky behaviors. Incorporation of these constructs may aid in the development of more efficacious clinical methods aimed at bettering health outcomes among bisexual women.

Normative Perceptions of Peer Drinking Distinguish High-Intensity Drinkers from Other Drinking Groups.

Background: High-intensity drinking (HID), or drinking that doubles the binge threshold (i.e., 8+/10+ drinks for women/men), is associated with more negative consequences than binge-only drinking. However, research focusing on HID and factors that may delineate HID from other drinking behaviors is lacking. The present study evaluated if perceived norms for peer drinking behavior (i.e., descriptive norms for alcohol quantity and frequency and injunctive norms) differentiated high-intensity drinkers from other drinker statuses. Further, we evaluated the role of perceived norms on odds of HID engagement and HID frequency. Finally, college status, sex, and underage drinker status were evaluated as moderators of the association between perceived norms and HID status/frequency. Methods: Participants were 623 emerging adult drinkers recruited via Craigslist (68.7% male; 69.0% White). Participants completed an online survey on their drinking behaviors and related social factors. Results: Each domain of perceived norms positively associated with drinker status. Higher perceived norms were associated with greater odds of HID and predicted HID frequency. The association between quantity and frequency descriptive norms and HID engagement was stronger for nonstudents and was only significant for males. Underage drinker status did not moderate associations between perceived norms and HID engagement. Conclusions: Findings provided evidence that perceptions of peer drinking behaviors are strong indicators of HID risk and may be especially useful for identifying high-intensity drinking males and nonstudents. The utility of perceived peer norms to differentiate this group of particularly risky drinkers suggests that social-influence-focused intervention approaches, including norms correction, may be efficacious in targeting HID among emerging adults.

Normative Perceptions of Sexual Behavior and Alcohol Use among Bisexual Women.

Background: As compared to heterosexual and lesbian women, bisexual women report higher rates of alcohol, other substance use, and risky sexual behavior, and they experience more negative outcomes from these behaviors. Descriptive norms (i.e., perceptions of others' behavior) are an important predictor of risky behaviors, but scant research has examined whether bisexual women's perceptions of other bisexual women's alcohol use and sexual behavior are associated with their own alcohol or drug use during sex. Objectives: Consequently, the present study examined (1) whether perceived sex norms were related to engagement in sex and (2) the relative influence of drinking and sex norms on engaging in sex while drinking among bisexual women. Method: Data were collected from 225 self-identified bisexual women who completed an online survey about their typical weekly alcohol use, engagement in alcohol or drug use during sex in the past 30 days, and normative perceptions of drinking and sexual behavior. Results: Regression models demonstrated both sexual norms and drinking frequency norms were positively associated with alcohol or drug use during sex. In addition, only perceived norms of other bisexual women, compared to perceived norms of lesbian and heterosexual women, predicted engagement in sex. Conclusions: Bisexual women may be susceptible to normative perceptions, given their connectedness to a marginalized social group. Thus, alcohol prevention and intervention efforts aimed at reducing risky consequences among bisexual women should specifically consider drinking and sexual norms of other bisexual women.

Daily Positive Alcohol Expectancies and Alcohol Use Outcomes among College Students.

Expectancy theory supports alcohol expectancies, or the expected effects of drinking, as an important factor in alcohol use behaviors. Recent research supports that alcohol expectancies fluctuate daily, but scant research has examined specific types of expectancies and their associations with alcohol use at the daily level. Consequently, the present study examined (1) the daily association between select expectancies (i.e., sociability, tension reduction, liquid courage) and likelihood of drinking, and (2) whether daily expectancies predict alcohol use outcomes (i.e., alcohol-related problems, heavy drinking) on drinking days. Participants (N = 221; 79.2% women) were primarily White (48.4%) and Black (29.7%) university students. Participants completed daily measures of expectancies, alcohol use, and alcohol-related problems each day for 14 days. Results from multilevel models revealed daily sociability as the only expectancy subscale linked with increased odds of drinking. Daily expectancies did not predict heavy drinking or alcohol-related problems on drinking days. At the between-person level, average levels of sociability and tension reduction expectancies were associated with a greater likelihood of engaging in heavy drinking and experiencing a problem. Findings highlight that fluctuations in sociability expectancies may be proximally linked to likelihood of alcohol use, which may inform just-in-time intervention efforts targeting alcohol expectancies.

Differential Pathways of Risky Drinking via Coping Motives in College and Noncollege Young Adults.

The current study tested a mediation model of psychological functioning (i.e., perceived stressors, psychological distress, and self-regulation) and risky drinking through a drinking to cope pathway comparing college and noncollege young adults. Participants were 623 young adult drinkers (M age = 21.46) who completed an online survey. Multigroup analyses examined the proposed mediation model for college students and nonstudents. For nonstudents, the indirect effects of psychological distress to alcohol use outcomes (i.e., alcohol quantity, binge drinking frequency, and alcohol-related problems) via coping motives was significant. Further, coping motives significantly mediated the positive effects of self-regulation on alcohol quantity, binge drinking frequency, and alcohol-related problems. For students, greater psychological distress was associated with greater coping motives, which in turn, related to greater alcohol-related problems. Coping motives significantly mediated the positive effect of self-regulation on binge drinking frequency. Findings highlight the different pathways that may result in risky drinking and alcohol problems based on young adult's educational attainment. These results have important clinical implications, particularly for those who have not attended college.

Alcohol, cannabis, and tobacco polysubstance use: A latent profile analysis of age of onset.

BACKGROUND: Despite understanding the long-term risks associated with early substance use, less is known about the specific patterns of the age of onset (AO) across multiple substances and whether these patterns of early exposure are linked to substance use later in young adulthood. Consequently, the present study sought to (1) identify distinct classes regarding AO for alcohol, cannabis, and tobacco and (2) compare these classes on patterns of individual and simultaneous alcohol, cannabis, and tobacco use, other substance use, and mental health symptoms. METHODS: Participants were 510 emerging adults (Mage = 21.35; 88.6% men) who reported past-year use of alcohol, cannabis, and tobacco. RESULTS: Latent profile analysis was used to identify classes based on three indicators: AO for alcohol, cannabis, and tobacco. Results revealed that four classes best fit the data: Earliest AO for Alcohol (19.8%); Latest AO for Substances (6.5%); Late AO for Substances (67.8%); Earliest AO for Cannabis and Tobacco (5.9%). Classes varied on current patterns of individual substance use, co-use of substances, other illicit drug use, and mental health symptomology. The Latest AO of Substances class reported the lowest alcohol use, cannabis use, other illicit drug use, and mental health symptomology than the other classes. The Earliest AO for Alcohol and the Late AO of Substances reported a lower frequency of tobacco compared to the other classes. The Late AO of Substance class reported the highest past-year frequency of simultaneous alcohol and cannabis use. CONCLUSIONS: The current study contributed to the larger polysubstance literature by identifying profiles that may signify risky patterns of use. Findings may help guide prevention and intervention work with adolescents and young adults.

Event-Specific Drinking and Protective Behavioral Strategy Use among College Students.

BACKGROUND: Event-specific drinking occasions (e.g. holidays, special occasions, school breaks) have been associated with heavy drinking and negative alcohol-related consequences among college students. The current study extends prior research by examining understudied holidays and changes in protective behavioral strategy use during these event-specific drinking occasions. METHOD: Participants were 537 college students between the ages of 18 and 24 who retrospectively reported drinking in the past two weeks. Several alcohol use variables (e.g., frequency, quantity, heavy episodic drinking frequency), negative alcohol-related consequences, and protective behavioral strategies were assessed for the previous 14 days. Ten event-specific drinking occasions were coded for the 14-day reporting period. A series of Analysis of Covariance models were conducted to examine differences on alcohol use variables, negative consequences, and protective behavioral strategies for weeks that included an event-specific drinking occasion relative to a no holiday reference timeframe. RESULTS: Compared to the no holiday reference group, several event-specific drinking occasions (e.g., Labor Day, Martin Luther King Day) were associated with greater alcohol use, negative consequences, and protective behavioral strategy use. In contrast, other occasions were determined to be low-risk holidays (e.g., Veterans Day) when protective behavioral strategies were less frequently used. Some occasions (e.g., spring break) did not exhibit the expected clear pattern of risk. CONCLUSIONS: College students' alcohol use, negative consequences, and protective behavioral strategy use vary across event-specific drinking occasions. Determining which event-specific drinking occasions are associated with risky alcohol use and the lowest use of harm reduction strategies is important for prevention and intervention programs.

Simultaneous Use of Alcohol and Marijuana: Patterns and Individual Differences.

Background: Simultaneous alcohol and marijuana (SAM) use, or using alcohol and marijuana in such a way that their effects overlap, is associated with negative health and behavioral outcomes. Objectives: Our study sought to fill gaps in our knowledge on this emerging public health concern by comparing SAM users and alcohol-only users on individual-level factors and substance use outcomes as well as examining associations of SAM use frequency, within users. Methods: Participants were recruited through online postings. Our analytic sample consisted of 1017 young adults (18-25 years) who reported past-month alcohol use. Most were male (67.8%), Caucasian (71.5%), and had attended at least some college (74.8%). Results: Past-year SAM users reported higher levels of sensation seeking and greater perceptions of their close friends' drinking behavior in comparison to alcohol-only users. SAM users reported heavier and more frequent alcohol use than alcohol-only users. Within past-year SAM users, 70% reported SAM use at least weekly. More frequent SAM use was associated with all alcohol use outcomes (e.g., weekly quantity, frequency, alcohol-related problems) and marijuana use outcomes (e.g., quantity, frequency, peak use) and higher drinking norms. Conclusions/Importance: It is clear that SAM users are a vulnerable sub-population of young adult drinkers. SAM users are differentiated from alcohol-only users in terms of their personality characteristics and perceptions of peer groups' drinking. SAM users and more frequent users are also at heightened risk for substance use outcomes. Prevention and intervention efforts targeting high-risk drinking may benefit from also assessing whether they simultaneously use alcohol and marijuana.

The Influence of a Brief Alcohol Intervention on Alcohol Use Trajectories in Nonstudent Emerging Adult Drinkers.

Background: This study sought to inform research with noncollege-attending emerging adults, an at-risk, and understudied population, by identifying patterns of response following a brief alcohol intervention. This study was a reanalysis of data from a randomized controlled intervention trial testing a brief, personalized feedback alcohol intervention targeting nonstudent emerging adult drinkers. Objectives: The study aims were to (1) model intervention response by identifying subgroups characterized by changes in heavy drinking (i.e. peak use, number of binges during a typical week, proportion of binge days, peak estimated blood alcohol concentration [eBAC]) following the alcohol intervention, and (2) distinguish subgroups on factors related to intervention response (i.e. perceived norms regarding how much peers drink, alcohol use severity, mental health symptoms, and readiness to change). Methods: Participants were 81 (64.2% men) nonstudent heavy drinkers between ages 18-25 years (average age = 22.04) recruited from the community. Results: Findings revealed two latent subgroups that exhibited differential response to the intervention (i.e. intervention "responders" and "nonresponders"). Further, responders reported higher pre-intervention descriptive normative perceptions and alcohol use severity. Conclusions/Importance: The current investigation contributed to knowledge regarding for whom brief alcohol interventions work in the short term within nonstudent emerging adults and could inform future research to facilitate behavior change in those unresponsive to intervention efforts.

Testing Daily Associations between Impulsivity, Affect, and Alcohol Outcomes: A Pilot Study.

BACKGROUND: Considerable research has examined impulsivity between individuals, but less research has focused on whether impulsivity fluctuates within a person. Although previous research supports trait levels of impulsivity as a risk factor for increased alcohol involvement, it is unclear whether daily (i.e., state) fluctuations in impulsivity coincide with same-day drinking behaviors. The present pilot study tested (1) the extent to which impulsivity fluctuates within-person; (2) the influence of daily impulsivity on alcohol use outcomes across all days (i.e., whether drinking occurred, the number of drinks consumed, and intentions to drink) and on drinking days only (i.e., whether heavy episodic drinking occurred and the number of problems experienced); and (3) daily affect as moderators of these relationships. METHOD: Participants were 24 young adult drinkers without postsecondary education who completed a baseline plus 14 follow-up daily surveys. Each day, participants reported their impulsivity, affect, and drinking behavior. RESULTS: Multilevel modeling revealed that 42.5% of the variability in daily impulsivity was due to within-person differences. Impulsivity was related to greater odds of heavy episodic drinking and more alcohol-related problems on drinking days. Positive affect moderated the relationship between impulsivity and alcohol-related problems, and the relationship between impulsivity and drinking intentions. CONCLUSIONS: Findings suggest that changes in positive affect and impulsivity may be a risk factor for alcohol problems in a daily context. Future research examining within-person impulsivity and negative outcomes may benefit from considering positive affect.

A Randomized Trial of a Personalized Feedback Intervention for Nonstudent Emerging Adult At-Risk Drinkers.

BACKGROUND: Emerging adulthood is a period of heightened vulnerability for problematic alcohol use. Considerable research has been devoted to reducing alcohol risks in college student populations, although far less effort has focused on their noncollege-attending peers. Research targeting nonstudent emerging adults is critical as this group is at risk of experiencing alcohol-related harms. Consequently, the main objective of the present randomized study was to examine the preliminary efficacy of a brief personalized feedback intervention (PFI) tailored for nonstudent at-risk drinkers. We also examined the influence of gender on intervention outcomes. Finally, we explored participant acceptability of the intervention. METHODS: Participants were 164 (65.9% men) emerging adults (M age = 21.98, SD = 2.02) recruited from the community. They were randomly assigned to either a 50-minute, in-person PFI or an assessment-only control group and were assessed over 9 months postintervention. RESULTS: Results showed that for short-term change (1 month), the PFI condition reduced drinking significantly more than controls. For longer-term change (1 to 9 months), both conditions continued to show gradual decline in consumption. The groups did not differ in alcohol-related problems, and the intervention was equally effective for both women and men. Regarding acceptability, participants were extremely satisfied with the intervention, perceived the information to be personally relevant, and thought it provided them a new way of looking at their own drinking. CONCLUSIONS: Overall, the present research advanced knowledge regarding an understudied and at-risk group of drinkers. This is among one of the first randomized studies to evaluate a brief intervention tailored to the needs of nonstudent emerging adults based on prior formative research with this group. Our data support PFI as a promising intervention approach for nonstudent drinkers in the community. Ultimately, this line of research aims to reduce alcohol-related health disparities associated with inequities in education.

Alcohol-Induced Impairment of Balance is Antagonized by Energy Drinks.

BACKGROUND: The acute administration of alcohol reliably impairs balance and motor coordination. While it is common for consumers to ingest alcohol with other stimulant drugs (e.g., caffeine, nicotine), little is known whether prototypical alcohol-induced balance impairments are altered by stimulant drugs. The purpose of this study was to examine whether the coadministration of a high-caffeine energy drink with alcohol can antagonize expected alcohol-induced increases in body sway. METHODS: Sixteen social drinkers (of equal gender) participated in 4 separate double-blind dose administration sessions that involved consumption of alcohol and energy drinks, alone and in combination. Following dose administration, participants completed automated assessments of balance stability (both eyes open and eyes closed) measured using the Biosway Portable Balance System. Participants completed several subjective measures including self-reported ratings of sedation, stimulation, fatigue, and impairment. Blood pressure and pulse rate were recorded repeatedly. RESULTS: The acute administration of alcohol increased body sway, and the coadministration of energy drinks antagonized this impairment. When participants closed their eyes, alcohol-induced body sway was similar whether or not energy drinks were ingested. While alcohol administration increased ratings of sedation and fatigue, energy drink administration increased ratings of stimulation and reduced ratings of fatigue. Modest increases in systolic and diastolic blood pressure following energy drink administration were also observed. CONCLUSIONS: Visual assessment of balance impairment is frequently used to indicate that an individual has consumed too much alcohol (e.g., as part of police-standardized field sobriety testing or by a bartender assessing when someone should no longer be served more alcohol). The current findings suggest that energy drinks can antagonize alcohol-induced increases in body sway, indicating that future work is needed to determine whether this observation regarding neuromotor functioning applies to alcohol in combination with all types of stimulant drugs.

Mediators and Moderators of a Personalized Feedback Alcohol Intervention for Nonstudent Emerging Adult Drinkers.

BACKGROUND: The main objective of this study was to test proposed mediators and moderators of a personalized feedback alcohol intervention (PFI) on alcohol use. Data for the current investigation came from an earlier randomized controlled trial of a PFI targeted for nonstudent heavy drinkers between 18 and 25 years. METHODS: Participants were 164 (65.9% men) drinkers recruited from the community. They were randomly assigned to either a single-session PFI or an assessment-only (AO) control group. Follow-up assessments at 1 and 3 months were included for analysis. RESULTS: Perceived drinking norms mediated the intervention effect on quantity, frequency, and peak drinking; 2 dimensions of protective behavioral strategies (PBS) mediated the intervention effect on peak drinking; and drinking to cope motives did not mediate any drinking outcomes. Of the moderating factors examined (i.e., norms, PBS, drink to cope motives, age, gender), only PBS related to serious harm reduction moderated intervention impact. Specifically, for those high in serious harm reduction PBS at baseline, postintervention reductions in drinking were stronger for the PFI group compared to AO. CONCLUSIONS: Overall, findings highlight the importance of correcting misperceived drinking norms and addressing the use of specific PBS in brief interventions. The knowledge gained from this study represents an important step toward minimizing drinking-related harms that are disproportionately experienced by those with lower educational attainment.

Testing a Model of Binegativity, Drinking-to-Cope Motives, Alcohol Use, and Sexual Coercion Among Self-Identified Bisexual Women.

In the present study, we tested a sequential mediation model whereby binegativity was associated with sexual coercion through drinking to cope motives and alcohol use. Data were examined from 224 self-identified bisexual women (M age = 22.79; SD = 3.44) who took part in an online survey. Participants reported binegativity, alcohol use, drinking to cope motivations, and sexual coercion experiences for the previous 30 days. A total of 48.0% of the sample (n = 108) experienced sexual coercion in the past 30 days. Sequential mediation indicated more experiences of binegativity were associated with greater drinking to cope motives, which in turn, related to greater alcohol frequency and greater likelihood of sexual coercion. Alcohol quantity was not a significant mediator. Results suggest the importance of studying the impact of binegativity on bisexual women, as well as developing prevention programs that consider how this form of discrimination may contribute to drinking to cope motives, more frequent alcohol use, and increased risk for sexual coercion.

An Examination of the Most Recent Episode of Molly Use among College Students.

OBJECTIVE: The current study examined event-level characteristics (e.g., contextual factors, risk behaviors) during the most recent episode of Molly use among a sample of college students who reported previously using Molly. PARTICIPANTS: Participants (N = 151; 66.7% female) were drinkers aged 18 to 25. Data were collected from October to November 2014, February to April 2015, and September to November 2015. METHOD: Participants completed measures regarding typical Molly use and items related to context and behaviors during their most recent episode of Molly use. RESULTS: Findings revealed that our sample most commonly reported using Molly earlier in the evening while hanging out with friends or at a party. Additionally, sexual and other drug use behaviors commonly occurred when using Molly. CONCLUSIONS: Findings provide preliminary information in guiding future work exploring Molly use and potential substance-related issues associated with the context of when and how Molly is consumed.

Desire to Drink Alcohol is Enhanced with High Caffeine Energy Drink Mixers.

BACKGROUND: Consumption of alcohol mixed with energy drinks (AmED) has been associated with a variety of risks beyond that observed with alcohol alone. Consumers of AmED beverages are more likely to engage in heavy episodic (binge) drinking. This study was to investigate whether the consumption of high caffeine energy drink mixers with alcohol would increase the desire to drink alcohol compared to the same amount of alcohol alone using a double-blind, within-subjects, placebo-controlled study design. METHODS: Participants (n = 26) of equal gender who were social drinkers attended 6 double-blind dose administration sessions that involved consumption of alcohol and energy drinks, alone and in combination. On each test day, participants received 1 of 6 possible doses: (i) 1.21 ml/kg vodka + 3.63 ml/kg decaffeinated soft drink, (ii) 1.21 ml/kg vodka + 3.63 ml/kg energy drink, (iii) 1.21 ml/kg vodka + 6.05 ml/kg energy drink, (iv) 3.63 ml/kg decaffeinated soft drink, (v) 3.63 ml/kg energy drink, and (vi) 6.05 ml/kg energy drink. Following dose administration, participants repeatedly completed self-reported ratings on the Desire-for-Drug questionnaire and provided breath alcohol readings. RESULTS: Alcohol alone increased the subjective ratings of "desire for more alcohol" compared to placebo doses. Energy drink mixers with the alcohol increased desire for more alcohol ratings beyond that observed with alcohol alone. CONCLUSIONS: This study provides laboratory evidence that AmED beverages lead to greater desire to drink alcohol versus the same amount of alcohol consumed alone. The findings are consistent with results from animal studies indicating that caffeine increases the rewarding and reinforcing properties of alcohol.

Alcohol use variability in a community-based sample of nonstudent emerging adult heavy drinkers.

BACKGROUND: While nonstudent emerging adults are at elevated risk for experiencing alcohol-related problems, there remains a paucity of research devoted specifically to addressing drinking in this group. OBJECTIVES: The present study sought to offer unique insights into nonstudent drinking by examining drinking variability across 30 days using a retrospective diary method. Specific aims were to: (1) compare within- and between-person variability in alcohol use across 30 days, and (2) determine the extent to which central social-cognitive between-person factors (i.e., social expectancies, perceived drinking norms, social drinking motivations) predict between-person alcohol use as well as within-person variability in drinking. METHODS: Participants were 195 (65.1% men) nonstudent emerging adults recruited from the community with a mean age of 21.9 (SD = 2.1) years. RESULTS: Findings showed that a substantial portion of variation in daily alcohol consumption was attributable to the within-person (83%) rather than between-person (17.2%) level. Social expectancies, perceived drinking norms, and social motives were found to influence variability in daily alcohol consumption. CONCLUSION: Our findings contribute to knowledge that could guide efforts to design and tailor intervention strategies to minimize the harms experienced by an understudied and at-risk population of drinkers.

Alcohol Expectancies Mediate the Relationship Between Age of First Intoxication and Drinking Outcomes in College Binge Drinkers.

BACKGROUND: While prior research has shown that age of first intoxication (AI) is associated with negative alcohol outcomes, limited research has examined factors accounting for this relationship. Alcohol expectancies, or beliefs about the effects of alcohol, may explain such associations as both positive and negative expectancies have been shown to be key predictors of drinking outcomes. OBJECTIVE: The present study examined expectancies as mediators between early AI and alcohol-related outcomes. METHOD: Data collection occurred in 2012 and 2013. Participants were college students (N = 562, 65.8% women) who completed an online survey including measures of alcohol use history, alcohol expectancies, typical alcohol consumption, and alcohol-related problems. Structural equation modeling was used to test the hypothesized model. RESULTS: Our findings support a model whereby AI is associated with drinking through its influence on both positive and negative expectancies. Specifically, an earlier AI was associated with stronger alcohol expectancies, which in turn, was associated with heavier alcohol use and alcohol-related problems. CONCLUSIONS/IMPORTANCE: These findings are consistent with expectancy theory and previous research suggesting that more experienced drinkers hold stronger drinking-related beliefs, be it positive or negative, and these expectancies ultimately explain variability in alcohol use and problems. Our findings further support that expectancies play an important role in the initiation of drinking behavior.

Molly users versus nonusers in a sample of college alcohol drinkers: Differences in substance-related harms and sensation seeking.

BACKGROUND: Molly is one form of MDMA (3,4-methylenedioxymethamphetamine) that is touted to be more "pure" and potentially less harmful than other forms, such as ecstasy. Media reports and case studies suggest that this drug is popular among college students and is related to adverse health problems. The current study sought to address the knowledge gaps about Molly by examining whether users differ in substance use outcomes and sensation seeking than nonusers. Specifically, this study tested whether Molly users engaged in heavier use of other substances and experienced more substance-related harms in general than nonusers. Further, the current study investigated whether Molly users exhibited higher levels of sensation seeking than nonusers. Lastly, this study examined whether Molly user status would be associated with substance-related harms beyond the confounding influence of other substance use and trait sensation seeking. METHODS: Participants were 710 (71.9% female) college alcohol drinkers who completed self-report surveys about substance use (i.e., Molly, alcohol, and other drug use), substance-related problems, and sensation seeking. RESULTS: Results revealed that approximately 12% of the sample reported lifetime Molly use. Molly users compared with nonusers reported higher levels of other drug use, alcohol use, substance-related problems, and sensation seeking. Further, Molly users reported experiencing poorer substance use outcomes (e.g., blacking out, academic/occupational problems, and withdrawal symptoms) after accounting for sensation seeking and other substance use. CONCLUSIONS: These findings indicate that Molly users are higher in sensation seeking and that use is uniquely related to greater risk for substance-related harms. These preliminary findings demonstrate a need for correcting possible misperceptions regarding the purity of Molly and educating users on the potential for experiencing associated harms. Such information could be used to develop efficacious prevention programming for college students.

Identifying Patterns of Situational Antecedents to Heavy Drinking among College Students.

BACKGROUND: Emerging adults have the highest prevalence of heavy drinking as compared to all other age groups. Given the negative consequences associated with such drinking, additional research efforts focused on at-risk consumption are warranted. The current study sought to identify patterns of situational antecedents to drinking and to examine their associations with drinking motivations, alcohol involvement, and mental health functioning in a sample of heavy drinking college students. METHOD: Participants were 549 (65.8% women) college student drinkers. RESULTS: Latent profile analysis identified three classes based on likelihood of heavy drinking across eight situational precipitants. The "High Situational Endorsement" group reported the greatest likelihood of heavy drinking in most situations assessed. This class experienced the greatest level of alcohol-related harms as compared to the "Low Situational Endorsement" and "Moderate Situational Endorsement" groups. The Low Situational Endorsement class was characterized by the lowest likelihood of heavy drinking across all situational antecedents and they experienced the fewest alcohol-related harms, relative to the other classes. Class membership was related to drinking motivations with the "High Situational Endorsement" class endorsing the highest coping- and conformity-motivated drinking. The "High Situational Endorsement" class also reported experiencing more mental health symptoms than other groups. CONCLUSIONS: The current study contributed to the larger drinking literature by identifying profiles that may signify a particularly risky drinking style. Findings may help guide intervention work with college heavy drinkers.
