Evanston Township High School (ETHS)
Strength in Numbers

Project Description

Evanston Township High School has approximately 3,033 students (2000-2001 enrollment figures) and 313 teachers and administrators. In April, 2001, Evanston Township High School (ETHS), in collaboration with the Evanston Substance Abuse Prevention Council, began a social norms marketing campaign targeted primarily at reducing the use of alcohol and tobacco among ETHS students.

Project Funding Sources

• The Chicago Community Trust (FY03 and FY04)
• The Evanston Community Foundation (FY02)
• Illinois Tobacco-Free Communities Evanston Health Department Grant (FY02 and FY03)
• The Illinois Department of Human Services (Staff support)
• The Rotary Club of Evanston Lighthouse (FY02 and FY03)
• First Congregational Church of Evanston (FY03)

In addition, 17 Evanston business have generously provided in-kind support to this project.

Project Objectives

The Strength in Numbers project objectives are to:

• Increase accurate perceptions among ETHS students, school staff, parents and other community members about the percentage of ETHS students who are not using tobacco and alcohol.
• Increase non-use of tobacco and alcohol among ETHS students.
• Increase positive, healthy behaviors among ETHS students.
• Increase the reinforcement of positive, health behaviors by parents and school staff.

The Strength in Numbers project goals are to:

• Achieve a 3-7% increase in reported non-use of alcohol and tobacco by ETHS students after the first year of the campaign.
• Achieve a 20% increase in the reported non-use of alcohol and tobacco by ETHS students after year 5 of the campaign.

Baseline Data

Baseline data collected from ETHS students (n = 2,010) in May 2001 indicate that:

• 83% of ETHS students do not smoke cigarettes, but ETHS students perceive that only 15% of their high school peers do not smoke.
• 53% of ETHS choose not to consume alcohol, but ETHS students perceive that only 8% of their high school peers do not drink.

Other baseline survey results include:

• 72% of ETHS students choose options other than drinking when they hang out with their friends.
• 95% of ETHS students have never used smokeless tobacco.
• 71% of ETHS students choose not to smoke marijuana.
• 73% of ETHS students have never smoked cigarettes.

Other important findings includes:

• School is the most widely used and most believable source of alcohol, tobacco and other drug information for ETHS students.
• Parents are the 2nd most believable source of ATOD information.

Normative Messages

With approximately three thousand students and over three hundred teachers, staff, and administrators, Evanston Township High School is not only large but also extremely diverse. Using a wide array of royalty-free, commercially purchased images of young people, project staff have been able to create normative media reflective of the school's tremendous diversity and its inclusive spirit. Messages have been specifically designed to support the concepts of power and choice—especially appealing notions to developing adolescents—and to promote the competence, care, and healthy behavior of the clear majority of students.

A typical example of the posters created is one with the message "Support your friends' healthy choices!" which includes specific avoidance tips derived from the students themselves: "Make a pact ahead of time not to drink. Leave parties together if there's drinking. Stand your ground—together." This upbeat message with its concrete behavioral suggestions is accompanied by the normative statement: "72% of ETHS students choose healthy options other than drinking when they're with their friends." Detailed information regarding the source of the normative data—such as the administration date and sample size of the survey—is also provided. Finally, the accompanying image of two smiling, teenage girls warmly embracing serves to visually reinforce the message.

Marketing Methods Employed

The marketing methods employed by the Evanston Social Norms campaign include:

• Posters
• Flyers
• Mailers
• Community Presentations
• Print/visual advertising
• Radio
• Promotional items (magnets, pens, water bottles, key chains, stress balls, screen savers)

Evanston Township High School students are of course the primary target audience for the normative messages. Additionally, ETHS parents, community members (n = 60,086) and middle school students have been identified as secondary target audiences for related normative messages.

Evaluation

After the first year of implementation, most key data points had trended in the desired direction; after two years, the data trends were even more broadly positive, such that:

• School staff reported increasing use of true norm messages to students regarding alcohol and cigarettes.
• School staff reported more accurate perceptions of the norms of nonuse by students.
• Parents reported increasing use of true norm messages regarding alcohol to students.
• Parents reported more accurate perceptions of the nonuse norms of students.
• Student perceptions of peer use of alcohol and cigarettes consistently declined, and
• Student use of alcohol and cigarettes was reduced.

Specifically, the 30-day measure of alcohol use dropped from 46% at Time 1 Baseline to 41% at Time 3 (2003), a 5 percentage point decline that represents an 11% reduction in prevalence.

Similarly, student 30-day use of cigarettes went from 16% at baseline to 12% at Time 3, a 4 percentage point drop equaling a 25% reduction in prevalence.

One notable aspect of this intervention is that the Center for Prevention Research and Development was contracted by the Illinois Department of Human Services to independently evaluate its effectiveness. Data for evaluation has been collected using self-report surveys, as well as perception of youth use survey administered to teachers, staff and parents.
