Impulsivity And Alcohol-Related Risk Among College Students: Examining Urgency, Sensation Seeking And The Moderating Influence Of Beliefs About Alcohol's Role In The College Experience, Joseph W. Labrie, Shannon R. Kenney, Lucy E. Napper, Kevin Miller

Heads Up!

The personality trait of impulsivity is predictive of heavy drinking and consequences among college students. The current study examined how impulsivity—measured via positive urgency, negative urgency, and sensation seeking—and a person's beliefs about the role alcohol plays in the college experience relate to drinking and consequences in a sample of 470 college students (mean age = 19 years, 61.3% female, 59.8% white). In support of hypotheses, sensation seeking independently predicted greater drinking, and both positive and negative urgency predicted greater experience of alcohol-related negative consequences after controlling for consumption level. Moreover, alcohol beliefs moderated the relationship between impulsivity types and …

Relational Aggression, Positive Urgency And Negative Urgency: Predicting Alcohol Use And Consequences Among College Students, Joseph W. Labrie, Elizabeth Grimaldi, Lucy Napper

Psychological Science Faculty Works

Research on relational aggression (indirect and social means of inflicting harm) has previously focused on adolescent populations. The current study extends this research by exploring both the frequency of perpetrating and being the target of relational aggression as it relates to alcohol use outcomes in a college population. Further, this study examines whether positive urgency (e.g., acting impulsively in response to positive emotions) and negative urgency (e.g., acting impulsively in response to negative emotions) moderate the relationship between relational aggression and alcohol outcomes. In this study, 245 college students (65.7% female) completed an online survey. Results indicated greater frequency of …

Use Of Protective Behavioral Strategies And Reduced Alcohol Risk: Examining The Moderating Effects Of Mental Health, Gender And Race, Shannon R. Kenney, Joseph W. Labrie

Heads Up!

Recent research indicates that protective behavioral strategies (PBS)—previously established as effective self-regulating tools for reducing alcohol risk among college students—may be especially useful for students with poor mental health, who are shown to be at heightened risk for alcohol-related harm. The current study examined the moderating influence of mental health (depression and anxiety severity), gender, and race (White, Asian) in the relationship between PBS use and alcohol-related negative consequences. Participants were 1,782 undergraduate students from two West Coast universities who reported past month incidence of heavy episodic drinking. Students reported on their drinking, experience of alcohol-related consequences, use of PBS, …

Rct Of Web-Based Personalized Normative Feedback For College Drinking Prevention: Are Typical Student Norms Good Enough?, Joseph W. Labrie, Melissa A. Lewis, David C. Atkins, Clayton Neighbors, Cheng Zheng, Shannon R. Kenney, Lucy E. Napper, Theresa Walter, Jason R. Kilmer, Justin F. Hummer, Joel Grossbard, Tehniat M. Ghaidarov, Sruti Desai, Christine M. Lee, Mary E. Larimer

Heads Up!

Objectives

Personalized normative feedback (PNF) interventions are generally effective at correcting normative misperceptions and reducing risky alcohol consumption among college students. However, research has yet to establish what level of reference group specificity is most efficacious in delivering PNF. This study compared the efficacy of a web-based PNF intervention employing eight increasingly-specific reference groups against a Web-BASICS intervention and a repeated-assessment control in reducing risky drinking and associated consequences.

Method

Participants were 1663 heavy drinking Caucasian and Asian undergraduates at two universities. The referent for web-based PNF was either the typical same-campus student, or a same-campus student at one (either …

Are They All The Same? An Exploratory, Categorical Analysis Of Drinking Game Types, Joseph W. Labrie, Phillip J. Ehret, Justin F. Hummer

Heads Up!

Drinking games have become a ubiquitous part of the college student drinking culture and are associated with drinking to intoxication and increased alcohol consequences. Contemporary research commonly considers drinking games holistically, with little to no consideration to the different drinking game types. The current study describes the creation of a novel DG categorization scheme and reports differences between DG categories. Participants were 3421 college students (58% female) who completed online surveys. Based on participant responses, 100 distinct drinking games were identified and defined. Two student focus groups were conducted in which drinking game definitions and rules were verified by students. …

Can You Say No? Examining The Relationship Between Drinking Refusal Self-Efficacy And Protective Behavioral Strategy Use On Alcohol Outcomes, Phillip J. Ehret, Tehniat M. Ghaidarov, Joseph W. Labrie

Heads Up!

Preliminary research has demonstrated reductions in alcohol-related harm associated with increased use of protective behavioral strategies (PBS) and higher levels of drinking refusal self-efficacy (DRSE). To extend research that has evaluated these protective factors independently of one another, the present study examined the interactive effects of PBS use and DRSE in predicting alcohol outcomes. Participants were 1084 college students (63% female) who completed online surveys. Two hierarchical linear regression models revealed that both DRSE and PBS use predicted alcohol use and consequences. Additionally, DRSE moderated the relationship between PBS use and both typical weekly drinking and negative alcohol-related consequences, such …

Event-Specific Risk And Ecological Factors Associated With Prepartying Among Heavier Drinking College Students, Justin F. Hummer, Lucy Napper, Phillip E. Ehret, Joseph W. Labrie

Heads Up!

Using event-specific data, the present study sought to identify relevant risk factors and risky drinking patterns associated with prepartying. Analyses focused on drinking outcomes as a function of drinking game playing and the social context on occasions where prepartying did and did not occur. This research utilized a representative two-site sample of prepartiers who also reported a heavy episodic drinking event in the past month (n = 988). Results revealed that during a preparty event, participants drank significantly more, reached higher blood alcohol levels (BALs), and experienced significantly more negative consequences compared to the last occasion that they drank but …

Injunctive Peer Misperceptions And The Mediation Of Self-Approval On Risk For Driving After Drinking Among College Students, Shannon R. Kenney, Joseph W. Labrie, Andrew Lac

Heads Up!

Of the alcohol-related risks faced by college students, it is arguable that none presents a greater public health hazard than driving after drinking (DAD). The present study examined the extent to which students’ injunctive misperceptions toward DAD predicted the likelihood to engage in DAD and how this relation was mediated by self-approval of DAD. Participants were 2,848 college students (59.1% female, 64.6% Caucasian) from two U.S. West Coast universities who completed confidential web-based surveys assessing DAD beliefs and behaviors. Results revealed that respondents tended to overestimate their peers’ approval toward DAD. Moreover, the subgroups likely to engage in DAD—men, 21+ …

First-Year College Women's Motivations For Hooking Up: A Mixed-Methods Examination Of Normative Peer Perceptions And Personal Hookup Participation, Shannon R. Kenney, Vandana Thadani, Tehniat Ghaidarov, Joseph W. Labrie

Psychological Science Faculty Works

This study used content analysis techniques to explore 221 first-year college women's perceptions of female peers’ reasons (i.e., normative perceptions) for hooking up. Data on personal participation in hooking up were also collected. The well-established Drinking Motives Questionnaire (Cooper, 1994) was used as a framework for coding positive (enhancement or social) and negative (coping or conformity) normative hookup motivations. Participants most commonly indicated that enhancement reasons motivated peers’ hookup behaviors (69.7%). Coping (23.5%), external (21.7%), social (19.5%), and conformity (16.3%) motives were cited less frequently. Furthermore, women who had hooked up since matriculating into college (61.5%, n = 136) were …

I Can Play All Night: Examining The Relationship Between Perceived Tolerance And Drinking Game Alcohol Consumption, Phillip J. Ehret, Joseph W. Labrie, Justin F. Hummer

Heads Up!

The present study examined the impact of perceived tolerance to alcohol on maximum alcohol consumption while playing drinking games. Participants were student drinkers (N=3,546) from two west coast universities. Among these students, 69.2% (n=2,290) reported playing a drinking game in the past month. Analyses demonstrated game players had higher perceived tolerances, and consumed more alcohol than non-game players. A regression model revealed that higher levels of perceived tolerance were related to increased maximal alcohol consumption while playing drinking games. Study limitations and implications for future research are discussed.

Predicting Driving After Drinking Over Time Among College Students: The Emerging Role Of Injunctive Normative Perceptions, Joseph W. Labrie, Lucy E. Napper, Tehniat M. Ghaidarov

Heads Up!

Objective:

Despite prevention efforts, driving after drinking (DAD) is a prevalent high-risk behavior among college students and is a leading cause of death and injury. Examination of factors predicting future DAD behavior is necessary to develop efficacious targeted interventions to reduce this behavior among college students. The current study evaluated demographic, social cognitive, and behavioral predictors of DAD using longitudinal data.

Method:

Participants were 655 nonabstaining college students (67.2% female; 60.3% White; Mage = 19.3 years) who completed online surveys at two time points 12 months apart.

Results:

Results revealed that participants consistently overestimated their peers’ approval (injunctive norms) …

Measuring College Students’ Motives Behind Prepartying Drinking: Development And Validation Of The Prepartying Motivations Inventory, Joseph W. Labrie, Justin F. Hummer, Eric R. Pedersen, Andrew Lac, Taona Chithambo

Heads Up!

Drinking motives are vital in identifying risk factors and better understanding alcohol-related outcomes. However, context-specific motivations could provide greater motivational perspective on high-risk context-specific alcohol use behaviors such as prepartying (consuming alcohol prior to attending one’s intended destination) than general alcohol motivations. In the current study, students’ open-ended responses to reasons for prepartying were collected from a large diverse sample (n = 2497), and the most commonly offered reasons were used to create a prepartying motivations inventory (PMI) that was then administered to a different sample (n = 1085). A split-half validation procedure was used for the purpose …

Prevalence, Social Contexts, And Risks For Prepartying Among Ethnically Diverse College Students, Andrew P. Paves, Joseph W. Labrie, Eric R. Pedersen, Justin F. Hummer, Joseph W. Labrie

Heads Up!

Prepartying, also known as pre-gaming, has emerged as a high-risk drinking event among U.S. college students. Research on factors related to prepartying behavior is in its relative infancy. The present study provides prevalence rates for prepartying across ethnic groups and examines how social context (whether prepartying took place with primarily male, female, or coed groups) and demographic factors may influence prepartying behavior. Participants were students from two West Coast universities (N = 2,546) whom identified as White, Asian and Pacific Islander American (APIA), Hispanic/Latino(a), or African American. The percentage of students who reported prepartying at least once in the …

Estimates And Influences Of Reflective Opposite-Sex Norms On Alcohol Use Among A High-Risk Sample Of College Students: Exploring Greek-Affiliation And Gender Effects, Justin F. Hummer, Joseph W. Labrie, Andrew Lac, Ashley Sessoms, Jessica Cail

Heads Up!

Reflective opposite sex norms are behavior that an individual believes the opposite sex prefers them to do. The current study extends research on this recently introduced construct by examining estimates and influences of reflective norms on drinking in a large high-risk heterosexual sample of male and female college students from two universities. Both gender and Greek-affiliation served as potential statistical moderators of the reflective norms and drinking relationship. All participants (N = 1790; 57% female) answered questions regarding the amount of alcohol they believe members of the opposite sex would like their opposite sex friends, dates, and sexual partners …

Global Sleep Quality As A Moderator Of Alcohol Consumption And Consequences In College Students, Shannon R. Kenney, Joseph W. Labrie, Justin F. Hummer, Andy T. Pham

Heads Up!

The authors examined the relationship between global sleep quality and alcohol risk, including the extent to which global sleep quality moderated the relationship between alcohol use and drinking-related consequences. Global sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) and alcohol-related consequences were assessed using the Rutgers Alcohol Problem Index (RAPI). The sample consisted of 261 college students (61.3% female, 58.2% Caucasian) who completed online surveys. Using a four-step hierarchical multiple regression model, global sleep quality was found to predict alcohol consequences, over and above assessed covariates (demographics and weekly drinking). Further, global sleep quality emerged as a …

Ethnicity Specific Norms And Alcohol Consumption Among Hispanic/Latino/A And Caucasian Students, Joseph W. Labrie, David C. Atkins, Clayton Neighbors, Tehniat Mirza, Mary E. Larimer

Heads Up!

Previous research has shown that social norms are among the strongest predictors of college student drinking and that normative misperceptions of more similar groups’ drinking behavior may be more influential on individual drinking than those groups perceived to be more different. However, limited research has explored the moderating role of ethnicity in this context. The current study examined the differential impact that Hispanic/Latino/a and Caucasian students’ normative perceptions of both typical and same-ethnicity college students’ drinking behavior had on their own drinking. Participants (N = 5,369 students; 60.4% female; 81.4% Caucasian; mean age 19.9 years) from two colleges completed …

How Drunk Am I? Misperceiving One’S Level Of Intoxication In The College Drinking Environment, Sean Grant, Joseph W. Labrie, Justin F. Hummer, Andrew Lac

Heads Up!

Objective

One effective event-level index that can assist in identifying risky intoxication levels among college students is blood alcohol concentration (BAC). Despite widespread exposure to BAC information, doubt exists as to whether American college students can accurately estimate their own BAC level or drinking behaviors while intoxicated. This study assessed whether students can accurately guesstimate their BAC level (gBAC) and drinking behaviors used to estimate BAC (eBAC) while drinking in social college settings

Method

Participants (N = 225; 56.4% male) consisted of emerging adults attending either a two- or four-year college who had at least one alcoholic drink within …

Examining The Relationships Between Acculturation Orientations, Perceived And Actual Norms, And Drinking Behaviors Of Short-Term American Sojourners In Foreign Environments, Eric R. Pedersen, Rick A. Cruz, Joseph W. Labrie, Justin F. Hummer

Heads Up!

As little research has examined factors influencing increased and heavy drinking behavior among American sojourners abroad, this study was designed to examine how acculturation orientations (i.e., separation versus assimilation), host country per capita drinking rates, and perceptions about the drinking behavior among other sojourners and natives in the host country predicted alcohol risk abroad. A sample of 216 American college students completing study abroad programs completed a pre-abroad questionnaire to document their pre-abroad drinking levels, followed by a post-return questionnaire to assess drinking while abroad, acculturation orientations and perceived norms of drinking behavior within the foreign environment. A dichotomous variable …

Comparing Greek-Affiliated Students And Student Athletes: An Examination Of The Behavior-Intention Link, Reasons For Drinking, And Alcohol-Related Consequences, Karen K. Huchting, Andrew Lac, Justin F. Hummer, Joseph W. Labrie

Heads Up!

While affiliation with Greek fraternities/sororities and intercollegiate athletic teams is associated with heavier drinking (Meilman et al., 1999), few studies have compared reasons for drinking among these groups. A sample of 1,541 students, identifying as either Greeks or athletes, completed an online survey. Athletes were significantly higher than Greeks on conformity reason for drinking. Tests of independent correlations indicated the magnitude of the past behavior to intention link was considerably stronger for Greeks. Greeks experienced significantly more social problems from drinking. Several group by gender ANOVA models found significant main effects with highest drinking rates, usually among Greek …

“This Would Be Better Drunk”: Alcohol Expectancies Become More Positive While Drinking In The College Social Environment, Joseph W. Labrie, Sean Grant, Justin F. Hummer

Heads Up!

The current study examined whether drinking and/or presence in the college social environment led to augmented positive alcohol expectancies among college students (N = 225). Participants were approached during popular drinking nights as they exited events at which alcohol was consumed or in front of their residence as they returned home. Participants completed a brief questionnaire that included an assessment of demographics, breath alcohol concentration (BrAC), and positive expectancies. Within 48 hours of baseline assessment, participants received via email a follow-up survey that re-assessed positive expectancies while sober. Positive sexual expectancies were more strongly endorsed while drinking in the …

Comparing Injunctive Marijuana Use Norms Of Salient Reference Groups Among College Student Marijuana Users And Nonusers, Joseph W. Labrie, Justin F. Hummer, Andrew Lac

Heads Up!

Marijuana is the most commonly used illicit drug among college students and has the potential for various negative outcomes. Perceptions of what constitutes typical approval/acceptability of a reference group (i.e. injunctive social norms) have been shown to have strong utility as predictors of health-risk behaviors in the college context, yet this construct remains significantly understudied for marijuana use despite its potential for use in social norms-based interventions. The current research evaluated individuals’ marijuana approval level and their perceptions of others’ marijuana approval level (i.e. injunctive norms) for various reference groups (typical student on campus, one’s close friends, one’s parents) as …

Identifying Factors That Increase The Likelihood Of Driving After Drinking Among College Students, Joseph W. Labrie, Shannon R. Kenney, Tehniat Mirza, Andrew Lac

Heads Up!

Driving after drinking (DAD) is a serious public health concern found to be more common among college students than those of other age groups or same-aged non-college peers. The current study examined potential predictors of DAD among a dual-site sample of 3,753 (65% female, 58% Caucasian) college students. Results showed that 19.1% of respondents had driven after 3 or more drinks and 8.6% had driven after 5 or more drinks in the past three months. A logistic regression model showed that male status, fraternity or sorority affiliation, family history of alcohol abuse, medium or heavy drinking (as compared to light …

Parents Know Best, But Are They Accurate? Parental Normative Misperceptions And Their Relationship To Students' Alcohol-Related Outcomes, Joseph W. Labrie, Justin F. Hummer, Phillip J. Ehret, Shannon R. Kenney

Heads Up!

Objective:

Parents often look to other parents for guidance, but how accurate are their perceptions? Expanding on existing normative literature to include parents of college students, this study first sought to determine whether parents accurately estimated the attitudes of other parents concerning their college student's alcohol-related behaviors. The effect of these (mis)perceived injunctive norms on the alcohol-related attitudes and behaviors of the parents' own children was then examined.

Method:

Participants were 270 college student-parent dyadic pairs who completed independent online surveys. The student sample was 59% female; the parent sample was 78% female.

Results:

A structural equation model demonstrated that …

Protective Behavioral Strategies Mediate The Effect Of Drinking Motives On Alcohol Use Among Heavy Drinking College Students: Gender And Race Differences, Joseph W. Labrie, Andrew Lac, Shannon R. Kenney, Tehniat Mirza

Heads Up!

Objective

This study examined the extent to which protective behavioral strategies (PBS) mediated the influence of drinking motives on alcohol consumption, and if these hypothesized relationships were corroborated across subsamples of gender and race.

Method

Online surveys were completed by 1592 heavy drinking college undergraduates from two universities (49.9% male and 50.1% female; 76.9% Caucasian and 23.1% Asian). Independent samples t-tests compared males and females as well as Caucasians and Asians on measures of drinking motives, PBS use, and alcohol consumption, and structural equation models examined the mediating role of PBS.

Results

Consistent with predictions, t-tests revealed that males reported …

Speech Production Deficits In Early Readers: Predictors Of Risk, Judith G. Foy, Virginia A. Mann

Psychological Science Faculty Works

Speech problems and reading disorders are linked, suggesting that speech problems may potentially be an early marker of later difficulty in associating graphemes with phonemes. Current norms suggest that complete mastery of the production of the consonant phonemes in English occurs in most children at around 6–7 years. Many children enter formal schooling (kindergarten) around 5 years of age with near-adult levels of speech production. Given that previous research has shown that speech production abilities and phonological awareness skills are linked in preschool children, we set out to examine whether this pattern also holds for children just beginning to learn …

Identifying Factors That Increase The Likelihood For Alcohol-Induced Blackouts In The Prepartying Context, Joseph W. Labrie, Justin F. Hummer, Shannon Kenney, Andrew Lac, Eric Pedersen

Heads Up!

The present study examined risk factors related to “blacking out” (e.g., temporary periods of memory loss during drinking) during preparty drinking events (i.e., pregaming, predrinking). Participants were students from two universities on the West Coast who reported past month prepartying (N = 2,546) in online surveys administered in the fall of 2008. Among these students, 25% (n = 636) reported blacking out during at least one occasion in which they prepartied in the past month. A logistic regression model underscored that Greek student affiliation, family history of alcohol abuse, frequency of prepartying, and both playing drinking games and …

Descriptive Drinking Norms: For Whom Does Reference Group Matter?, Mary E. Larimer, Clayton Neighbors, Joseph W. Labrie, David C. Atkins, Melissa A. Lewis, Christine M. Lee, Jason R. Kilmer, Debra L. Kaysen, Eric R. Pedersen, Heidi Montoya, Kimberley Hodge, Sruti Desai, Justin F. Hummer, Theresa Walter

Heads Up!

Objective:

Perceived descriptive drinking norms often differ from actual norms and are positively related to personal consumption. However, it is not clear how normative perceptions vary with specificity of the reference group. Are drinking norms more accurate and more closely related to drinking behavior as reference group specificity increases? Do these relationships vary as a function of participant demographics? The present study examined the relationship between perceived descriptive norms and drinking behavior by ethnicity (Asian or White), sex, and fraternity/sorority status.

Method:

Participants were 2,699 (58% female) White (75%) or Asian (25%) undergraduates from two universities who reported their own …

Ovarian Hormones, Aging And Stress On Hippocampal Synaptic Plasticity, Michael R. Foy

Psychological Science Faculty Works

The ovarian steroid hormones estradiol and progesterone regulate a wide variety of non-reproductive functions in the central nervous system by interacting with molecular and cellular processes. A growing literature from studies using rodent models suggests that 17β-estradiol, the most potent of the biologically relevant estrogens, enhances synaptic transmission and the magnitude of long-term potentiation recorded from in vitro hippocampal slices. In contrast, progesterone has been shown to decrease synaptic transmission and reduce hippocampal long-term potentiation in this model system. Hippocampal long-term depression, another form of synaptic plasticity, occurs more prominently in slices from aged rats. A decrease in long-term potentiation …

Testing A Model Of Minority Identity Achievement, Identity Affirmation And Psychological Well-Being Among Ethnic Minority And Sexual Minority Individuals, Negin Ghavami, Adam W. Fingerhut, Letitia A. Peplau, Sheila K. Grant, Michele A. Wittig

Psychological Science Faculty Works

How is social identity related to psychological well-being among minority individuals? Drawing on developmental models of identity formation (e.g., Erikson, 1968) and on Social Identity Theory (Tajfel & Turner, 1979), we tested a conceptual model examining links between two key aspects of social identity and psychological well-being. We proposed that the association between identity achievement (exploring and understanding the meaning of one's identity) and psychological well-being is mediated by identity affirmation (developing positive feelings and a sense of belonging to one's social group). Across three studies, including ethnic minority high school students (Study 1), ethnic minority college students (Study 2) …

Reducing Alcohol Risk In Adjudicated Male College Students: Further Validation Of A Group Motivational Enhancement Intervention, Joseph W. Labrie, Jessica Cail, Eric R. Pedersen, Savannah Migliuri

Heads Up!

This study examined the effectiveness of a single-session group motivational enhancement alcohol intervention on adjudicated male college students. Over two sequential academic years, 230 students sanctioned by the university for alcohol-related infractions attended a 60- to 75-minute group intervention. The intervention consisted of a timeline followback, social norms education, decisional balance for behavioral change, blood alcohol content (BAC) information, expectancy challenge, and generation of behavioral goals. Participants were followed weekly for three months and showed reductions in drinking (29%) and alcohol-related consequences (32%) at three-month follow-up. The intervention was successful in reducing drinking for both first-year students and upperclassmen, with …
