1 An Overview of Environmental Prevention Since the NIAAA Call to Action Robert Saltz, Ph.D. Prevention Research Center Pacific Institute for Research & Evaluation Berkeley, California

2 Why Care About College Student Drinking? Over 1,700 deaths among year old college students 590,000 unintentionally injured under the influence of alcohol More than 690,000 assaulted by another student who has been drinking More than 97,000 are victims of alcohol-related sexual assault or date rape About 25 percent of college students report academic consequences of their drinking including missing class, falling behind, doing poorly on exams or papers, and receiving lower grades overall

5 Task Force Recommendations Tier 1: Evidence of Effectiveness Among College Students Tier 2: Evidence of Success With General Populations That Could Be Applied to College Environments Tier 3: Evidence of Logical and Theoretical Promise, But Require More Comprehensive Evaluation Tier 4: Evidence of Ineffectiveness

6 Recommendations Tier 1 Combining cognitive-behavioral skills with norms clarification and motivational enhancement interventions Offering brief motivational enhancement interventions Challenging alcohol expectancies

7 So Why Not Just Take One of Those? Most targeted to high-risk drinkers Difficult to implement with fidelity Labor intensive Costly for large populations.work continues on all these limitations

9 Recommendations Tier 2 Increased enforcement of minimum drinking age laws Implementation, increased publicity, and enforcement of other laws to reduce alcoholimpaired driving Restrictions on alcohol retail outlet density Increased price and excise taxes on alcoholic beverages Responsible beverage service policies in social and commercial settings

10 Environmental Policies to Reduce College Drinking: An Update of Research Findings Toomey, Lenk, & Wagenaar (2007) Journal of Studies on Alcohol and Drugs

11 Correlational Studies Outlet density near campuses associated with alcohol consumption and problems Weitzman et al, 2003a; Williams, et.al, 2004; Wechsler et. al, 2002 Price, promotion, taxes related to consumption Weitzman, et al, 2003b; Williams, et.al., 2004; Kuo, et.al Reduced access to alcohol Dry Campus tied to lower use (maybe not in high density environments) Wechsler, et. al, 2001a; Williams, et.al, 2004, 2005 Alcohol-Free Residences vs. Substance-Free Residences Williams, et.al., 2004; Wechsler, et.al, 2001a&b Having more local and state alcohol policies is related to lower high-risk drinking (Nelson, et.al, 2005a)

12 Opportunistic Studies Controlled Access Keg ban increased consumption (Kilmer, et.al, 1999) Alcohol-free residences and Greek housing lowers prevalence, but not high-risk drinking (Odo, et.al, 1999) Stadium ban lowers problems (Borman & Stone, 2001) Social norms campaigns Reduced consumption: Glider, et.al, 2001; Mattern and Neighbors, 2004; Smith et.al, 2006 but not always Clapp, et.al, 2003 Multi-component Interventions Homecoming Game (Johannessen, et.al, 2001) Massachusetts State campuses (Knight, et.al, 2003) Albany Campus-Community Intervention (Gebhardt, et.al, 2000)

17 Project Summary Aims: Examine effectiveness of environmental management (EM) interventions delivered through an existing campus-community coalition Decrease Access Increase Enforcement Publicized through RhodeMap to Safety Campaign Status U18 Grant: U01 Grant:

18 Outcomes Student surveys Four annual student surveys (N ~ 500) Series of ANOVA s examining awareness of efforts, perceptions of enforcement and alcohol availability, and behaviors Archival data Police reports of student incidents in community

19 Heard About DUI Enforcement Perc. DUI Enforcement RMS Linear Trend**** **** **** Year **** **** p <.0001

20 Likelihood of Drinking and Driving Consequences Likelihood of D & D Cons RMS Linear Trend**** **** **** **** Year **** p <.0001

21 Self-Reported Behaviors No significant differences on: Alcohol-impaired driving Composite measure of alcohol use Alcohol use at off-campus parties Reported difficulty finding off campus parties Summary of survey data Consistent effects on awareness and perceptions/consequences of enforcement of EM strategies No evidence for impact on self-reported alcohol use or drinking and driving

22 Campus Community Strategy to Change the Drinking Culture Western Washington University Bellingham, Washington

23 Campus Community Strategy to Change the Drinking Culture Primary Aims 1. To test and evaluate the efficacy of limiting college student access to alcohol though increased enforcement of minimum drinking age laws in the WWU-Bellingham campus community. 2. To pilot test and evaluate the efficacy of the Neighborhoods Engaging with Students (NEST) Project, a multi-component environmental intervention that increases the bonds of students to campus and community and enhances their sense of belonging and responsibility.

24 Project Components Neighborhoods Engaging with Students (NEST) Enforcement Campus Community Coalition work groups were involved in planning, implementation, and process evaluation.

25 Project Evaluation 3 intervention neighborhoods (Bellingham) WWU and two comparison campuses Student Voices Survey,»Online, Fall 05 and Fall 06»Sample size, response rates»incentive structure Enforcement data Implementation/process measures

30 Controlled Interventions San Diego DUI Intervention Clapp, et.al., 2005 A Matter of Degree Weitzman, et.al., 2004 Social Norms Marketing DeJong, et.al., 2006 > Safer California Universities Saltz, et.al., under review

31 Social Norms Marketing Research Project National Institute on Alcohol Abuse and Alcoholism and U.S. Department of Education R01 AA 12471

32 Students have exaggerated views of how much other students drink Students perceive greater normative expectations to drink Students increase alcohol consumption

33 Social Norms Marketing Use campus-based media to report accurate drinking norms Decrease in perceived normative expectations to drink Decrease in alcohol consumption

48 Objectives of the Guide to Planning and Evaluation To facilitate successful adoption by college campuses of NIAAA Task Force recommendations To foster integration of evaluation into prevention programs and policies To increase chances of success for any campus prevention initiative

49 Reducing Alcohol Problems on Campus: A Guide to Planning and Evaluation Introduction

50 Reducing Alcohol Problems on Campus: A Guide to Planning and Evaluation Introduction Steps for Effective Prevention Planning and Evaluation

51 Steps for Effective Prevention Planning and Evaluation Identify Specific Goals and Objectives What exactly is the objective? The role of needs assessment Choose intervention after setting objectives The more specific the better

52 Steps for Effective Prevention Planning and Evaluation Identify Specific Goals and Objectives Review Research on College Drinking Interventions Consult typology of programs within Social Ecological Framework Match strategy with objectives

53 Steps for Effective Prevention Planning and Evaluation Outline How the Intervention Will Work Perhaps most important step Develop a Logic Model

54

55 Alcohol-involved traffic crashes Distal outcome Media advocacy training Technical assistance Additional officer hours Breathalyzers Training Checkpoints Project inputs DUI news coverage DUI enforcement Community outputs Perceived risk of arrest Drinking and driving Intermediate variables

56 Alcohol-Related Motor Vehicle Crash Causal Model Alcohol Sales & Service Regulations, Enforcement & Sanctions DUI Enforcement Community activism about DUI enforcement Public Awareness of Drinking/Driving Enforcement Price Retail Availability Alcohol Serving and Sales Practices Perceived Risk of DUI Arrest Community Norms Drinking and Driving Alcohol Promotion Drinking Driving After Drinking Alcohol-Related Motor Vehicle Crashes Community Norms - Drinking Individual Factors Social Availability Strong Relationship Drinking Context Moderate Relationship Minor Relationship Little Empirical Evidence but logical relationship

57 Why the Logic Model is critical Will pinpoint areas of uncertainty, confusion or disagreement among team Can expose potential false assumptions Help guarantee that activities are linked to specific objectives Can later serve as educational tool Can be used to track changes in intervention Helps inform the evaluation

58 Steps for Effective Prevention Planning and Evaluation Identify Specific Goals and Objectives Review Research on College Drinking Interventions Outline How the Intervention Will Work Create and Execute a Data Collection Plan Communicate Evaluation Results

61 Typical Hurdles for Comprehensive Prevention Strategy Implicit assumption that the only target is high-risk drinkers Ambivalence about student drinking Low perceived efficacy of preventive interventions Challenges of coordination and resource allocation Possible fears of backlash

62 Unique Hurdles for College Prevention Emphasis on process over outcome Preference for persuasion over control Universities are complex, diffuse organizations Prevention staff trained in education, awareness strategies Prevention staff usually lacks authority to launch initiatives

63 Use Evaluation at All Points to Achieve Intervention Success

64 Future Research: Where are we heading? Evaluating Full-Spectrum Comprehensive Interventions Replications Effectiveness Studies (with emphasis on mediators and moderators) Diffusion Research Basic Research on Organizational and Community Change
