Item A Randomized Controlled Trial of Event Specific Prevention Strategies for Reducing Problematic Drinking Associated with 21st Birthday Celebrations(Journal of Consulting and Clinical Psychology, 2012) Neighbors, Clayton; Lee, Christine M.; Atkins, David C.; Lewis, Melissa A.; Kaysen, Debra; Mittmann, Angela; Fossos, Nicole; Geisner, Irene M.; Zheng, Cheng; Larimer, Mary E.Objective: While research has documented heavy drinking practices and associated negative consequences of college students turning 21, few studies have examined prevention efforts aimed to reduce high-risk drinking during 21st birthday celebrations. The present study evaluated the comparative efficacy of a general prevention effort (i.e., BASICS) and event specific prevention in reducing 21st birthday drinking and related negative consequences. Furthermore, this study evaluated inclusion of peers in interventions and mode of intervention delivery (i.e., in-person vs. web). Method: Participants included 599 college students (46% male) who intended to consume at least five/four drinks (men/women respectively) on their 21st birthday. After completing a screening/baseline assessment approximately one week before turning 21, participants were randomly assigned to one of six conditions: 21st birthday in-person BASICS, 21st birthday web BASICS, 21st birthday in-person BASICS plus friend intervention, 21st birthday web BASICS plus friend intervention, BASICS, or an attention control. A follow-up assessment was completed approximately one week after students’ birthdays. Results: Results indicated a significant intervention effect for BASICS in reducing blood alcohol content reached and number of negative consequences experienced. All three in-person interventions reduced negative consequences experienced. Results for the web-based interventions varied by drinking outcome and whether or not a friend was included. Conclusions: Overall, results provide support for both general intervention and ESP approaches across modalities for reducing extreme drinking and negative consequences associated with turning 21. These results suggest there are several promising options for campuses seeking to reduce both use and consequences associated with 21st birthday celebrations.Item Event specific drinking among college students(Psychology of Addictive Behaviors, 2011-12) Neighbors, Clayton; Atkins, David C.; Lewis, Melissa A.; Lee, Christine M.; Kaysen, Debra; Mittmann, Angela; Fossos, Nicole; Rodriguez, Lindsey M.College represents a period of risk for heavy drinking and experiencing unwanted consequences associated with drinking. Previous research has identified specific events including holidays (e.g., New Years), school breaks (e.g., Spring Break) and personally relevant events (e.g., 21st birthdays) that are associated with elevated risk of heavy drinking and negative alcohol-related consequences. The systematic evaluation of relative risk offers insights into event specific drinking and an empirical basis upon which to consider allocation of limited prevention resources. Thus, the purpose of the present study was to provide a comparative index of drinking across a wide range of holidays and compare holiday drinking to 21st birthday drinking. Participants were 1,124 students (55% female) who had turned 21 within the previous three weeks in 2008 and provided 90-day retrospective reports of their drinking using the Timeline Follow-back. Results based on a hurdle mixed model for blood alcohol content (BAC) revealed several holidays that stand out for elevated drinking, including New Year’s Eve and July 4th, whereas other holidays appear more similar to weekend drinking, such as Spring Break (approximately last week of March) and graduation (mid-June). Drinking on holidays or special days was substantially lower than drinking on 21st birthdays. Results are discussed in terms of practical applications for targeted intervention efforts on college campuses toward specific events where elevated drinking is known to occur.Item Habit doesnʼt make the predictions stronger: Implicit alcohol associations and habitualness predict drinking uniquely(Addictive Behaviors, 2015-06) Lindgren, Kristen P.; Neighbors, Clayton; Teachman, Bethany A.; Gasser, Melissa L.; Kaysen, Debra; Norris, Jeanette; Wiers, Reinout W.Introduction: As research on implicit (in the sense of fast/reflexive/impulsive) alcohol associations and alcohol advances, there is increasing emphasis on understanding the circumstances under which implicit alcohol associations predict drinking. In this study, we investigated habitualness of drinking (i.e., the extent to which drinking is automatic or occurs without thinking) as a moderator of the relations between several measures of implicit alcohol associations and key drinking outcomes. Method: A sample of 506 participants (57% female) completed web-based measures of implicit alcohol associations (drinking identity, alcohol approach, and alcohol excitement), along with indicators of habitualness, and typical alcohol consumption, alcohol problems, and risk of alcohol use disorders. Results: As expected, implicit alcohol associations, especially drinking identity, were positively associated with, and predicted unique variance in, drinking outcomes. Further, habitualness emerged as a consistent, positive predictor of drinking outcomes. Contrary to expectations, habitualness rarely moderated the relation between implicit alcohol associations and drinking outcomes. Conclusions: Although moderation was rarely observed, findings indicated that even mild levels of habitualness are risky. Findings also continue to support implicit alcohol associations, particularly drinking identity, as a risk factor for hazardous drinking. Collectively, this suggests the importance of targeting both in prevention and intervention efforts.Item Implicit alcohol associations, especially drinking identity, predict drinking over time(Health Psychology, 08/01/16) Lindgren, Kristen P.; Neighbors, Clayton; Teachman, Bethany A.; Baldwin, Scott A.; Norris, Jeanette; Kaysen, Debra; Gasser, Melissa L.; Wiers, Reinout W.There is considerable excitement about implicit alcohol associations (IAAs) as predictors of college-student hazardous drinking; however, few studies have investigated IAAs prospectively, included multiple assessments, or controlled for previous drinking. Doing so is essential for showing the utility of these associations as predictors, and ultimately, targets for screening or intervention. Therefore, 3 IAAs (i.e., drinking identity, alcohol approach, and alcohol excitement) were evaluated as prospective predictors of drinking in 1st- and 2nd-year undergraduates in the United States.A sample of 506 undergraduates completed 8 online assessments of IAAs, explicit measures of the IAA constructs, and hazardous drinking (i.e., consumption, problems, and risk of alcohol-use disorders) every 3 months over a 21-month period. Retention rates, ordered by follow-up time points, were 90%, 76%, 76%, 77%, 72%, 67%, and 66%, respectively. Half of the participants were nondrinkers at baseline; 21% were above clinical cutoffs for hazardous drinking.Drinking-identity and alcohol-excitement associations predicted future alcohol consumption and problems after controlling for previous drinking and explicit measures; drinking identity also predicted future risk of alcohol-use disorder. Relative to the other IAAs, drinking identity predicted alcohol consumption for the longest duration (i.e., 21 months). Alcohol-approach associations rarely predicted variance in drinking.IAAs vary in their utility as prospective predictors of college-student hazardous drinking. Drinking identity and, to a lesser extent, alcohol excitement, emerged as robust prospective predictors of hazardous drinking. Intervention and screening efforts could likely benefit from targeting those associations.Item Randomized controlled trial of a spring break intervention to reduce high-risk drinking(Journal of Consulting and Clinical Psychology, 2014-04) Lee, Christine M.; Neighbors, Clayton; Lewis, Melissa A.; Kaysen, Debra; Mittmann, Angela; Geisner, Irene M.; Atkins, David C.; Zheng, Cheng; Garberson, Lisa A.; Kilmer, Jason R.; Larimer, Mary E.Objective: While recent studies have documented high-risk drinking occurring during Spring Break (SB), particularly on SB trips with friends, published intervention studies are few. The present study evaluated the efficacy of Event Specific Prevention (ESP) strategies for reducing SB drinking among college students, compared to general prevention strategies and an assessment-only control group, as well as evaluated inclusion of peers in interventions and mode of intervention delivery (in-person vs. web). Method: Participants included 783 undergraduates (56.1% women, average age 20.5) intending to go on a SB trip with friends as well as to drink heavily on at least one day of SB. Participants completed assessments prior to SB and were randomized to one of five intervention conditions: SB in-person BASICS, SB web BASICS, SB in-person BASICS with friend, SB web BASICS with friend, general BASICS, or an attention control condition. Follow-up assessment was completed one week after SB. Results: While the SB web BASICS (with and without friends) and general BASICS interventions were not effective at reducing SB drinking, results indicated significant intervention effects for SB in-person BASICS in reducing SB drinking, particularly on trip days. Follow-up analyses indicated change in descriptive norms mediated treatment effect and reductions in drinking, while SB drinking intentions and positive expectancies did not. Conclusions: Overall, results suggest an in-person SB-specific intervention is effective at reducing SB drinking, especially during trips. In contrast, interventions that contain non-SB related content, are web-based, or seek to involve friends may be less effective at reducing SB drinking.Item Spring Break versus Spring Broken: Predictive utility of Spring Break alcohol intentions and willingness at varying levels of extremity(Prevention Science, 2014-02) Litt, Dana M.; Lewis, Melissa A.; Patrick, Megan E.; Rodriguez, Lindsey M.; Neighbors, Clayton; Kaysen, DebraObjective: Within the domain of risk-related behavior, many times the decision to engage is not a product of premeditation or intention. The Prototype Willingness model was created to capture and explain the unintended element of risk behavior. The present study aimed to evaluate the importance of willingness versus intention, two important constructs within the Prototype Willingness model, in relation to Spring Break drinking behavior when assessed at both high and low extremities. Method: College undergraduates (N = 275) completed questionnaires prior to Spring Break regarding their anticipated Spring Break activities. Willingness and intention were assessed for different levels of risk. Specifically, participants indicated the extent to which they intended to (a) get drunk and (b) drink enough to black out or pass out; and the extent to which they were willing to (a) get drunk and (b) drink enough to black out or pass out. When classes resumed following Spring Break, the students indicated the extent to which they actually (a) got drunk and (b) drank enough to black out or pass out. Results: Results demonstrated that when the health-related risk was lower (i.e., getting drunk), intention was a stronger predictor of behavior than was willingness. However, as the level of risk increased (i.e., getting drunk enough to black out or pass out), willingness more strongly predicted behavior. Conclusion: The present study suggests that willingness and intentions differentially predict Spring Break alcohol-related behavior depending on the extremity of behavior in question. Implications regarding alcohol interventions are discussed.
