A study just published by Henry Wechsler et al. in the
Journal of Studies on Alcohol1 claims to question the effectiveness
of using the social norms approach to address high-risk alcohol consumption
among college students.
The professed aim of this study was "to determine whether
schools that use social norms marketing campaigns experience reductions
in students' heavy-drinking behaviors and to compare any observed changes
with the experience of schools that do not use such programs." However,
the method used to identify schools that employ social norms marketing
programs was methodologically unsound. The only criterion used to identify
such programs was the response to one item on a survey sent to school
administrators in 2001. This sole relevant question "asked whether or
not each school had 'ever conducted a "social-norms" campaign to decrease
alcohol use and related problems on campus'; and if it had, the time
period during which the program was conducted."
There are some obvious criticisms that can be made of
a study that is based on such an ill-defined response category.
First, and most significantly, no other survey data
was collected about the extent or quality of these reported programs,
and the authors themselves admit that they made no additional efforts,
such as campus visits, "to determine the content, scope and duration"
of them.
For an administrator to report that his or her institution
has "ever conducted a social norms campaign" is not the same
as saying that the school has conducted a comprehensive social norms
marketing campaign. Increasingly, colleges and universities routinely
incorporate positive norm messages regarding a variety of issues into
student orientation programs, health education sessions, etc., and it
is both important and appropriate that they do so. However, "using social
norms" in this limited way is qualitatively different than conducting
a comprehensive social norms marketing campaign. The latter necessarily
requires a larger commitment of institutional resources. Both are valid,
of course, and reflect the fact that each institution can only operate
within the context of what it deems possible. Nevertheless, the fact
remains that these important qualitative differences will be masked
when a school administrator merely responds that his or her institution
has "ever conducted a social norms campaign."
This point is additionally important because no attempt
was made to assess what other programs or initiatives were in place
at each school, some of which may well have mitigated if not actually
counteracted the effect a properly conducted social norms marketing
campaign.
Second, the method employed in this study is arguably
susceptible to the Rosenthal effect, where investigator expectancies
inadvertently communicated to study participants may effect how respondents
score in a study (Rosenthal, 1966), as well as to so-called demand characteristics,
where participants in a study may reply to questions based on their
perception of the goal of the investigation (Orne, 1962). Thus, an number
of administrators—given the high-profile nature of the issue of
alcohol on college campuses—may have felt compelled to respond
affirmatively to an inquiry from the Harvard School of Public Health
about whether or not they ever conducted "a social-norms campaign to
decrease alcohol use and related problems on campus."
These two criticisms cast serious doubt as to whether
this study actually does what it purports to do: i.e., measure the effectiveness
of social norms marketing interventions in reducing college students'
heavy use of alcohol. In the face of growing evidence of the effectiveness
of the social norms approach, college administrators and health educators
would do well to base their programmatic efforts on a full review of
the literature.
Examples of successful social norms programs with documented
reductions in high-risk drinking and negative consequences include:
Hobart and William Smith Colleges - 32% reduction
over 4 years
See: Perkins, H. W. and Craig, D. (2002) A
Multifaceted Social Norms Approach to Reduce High-Risk Drinking.
Newton, MA: The Higher Education Center for Alcohol and Other Drug Prevention,
Education Development Center, Inc.
Provides a comprehensive presentation of the Hobart and William Smith
Colleges' Social Norms Project, which achieved a 30% reduction in high-risk
drinking over 5 years. Contents include a complete description of program
components, including data collection, print media campaigns, electronic
media campaigns, curriculum development, and campus presentations.
Northern Illinois University - 44% reduction over 9
years

A Case Study of the Social Norms Approach," (2003) in The Social Norms
Approach To Preventing School And College Age Substance Abuse: A Handbook
For Educators, Counselors, And Clinicians, Ed. H. Wesley Perkins. San
Francisco: Jossey-Bass.
This book chapter presents the first applied experiment using the
approach in a college student population. The experiment used print
media and co-curricular activities publicizing actual norms to change
perceptions and, in turn, documented a dramatic and continuing decline
in heavy drinking among students.
Rowan University - 25% reduction over 3 years
See: Jeffrey, L., P. Negro, D. Miller and J. Frisone.

Approach To Preventing School And College Age Substance Abuse: A Handbook
For Educators, Counselors, And Clinicians, Ed. H. Wesley Perkins. San
Francisco: Jossey-Bass.
This book chapter reports a replication of the social norms intervention
approach with print media at an East Coast university. Assessment results
demonstrate that as exposure to campaign materials increased each year
a corresponding reduction in high risk drinking was the result.
University of Arizona - 27% reduction over 3 years
See: Johannessen, K., "The University of Arizona's
Campus Health Social Norms Media Campaign," (2003) in The Social Norms
Approach To Preventing School And College Age Substance Abuse: A Handbook
For Educators, Counselors, And Clinicians, Ed. H. Wesley Perkins. San
Francisco: Jossey-Bass. This book chapter reports on a replication
of the Northern Illinois University print media strategy to reduce misperceptions
that refined and further developed the production of media images and
applied the strategy in a large southwestern university context. Again,
a significant reduction in heavy drinking was the result.
