Introduction
“Social Norms”
is a theory and evidence-based approach to addressing health issues that has gained
increasing attention. A social norms intervention have been successful in
reducing alcohol and tobacco use in college and high school populations, and
has promise as an intervention to address violence and social justice issues.
As a result of these successes, practitioners in the field of social norms have
received national recognition for their work and social norms programs have
received a number of best practice awards from Federal agencies. Currently
social norms interventions are being funded by the United States Department of
Education, the Department of Justice, and the Centers for Disease Control,
state health departments, private foundations, and in some cases, the beverage industry.
In addition, four large outcome studies funded by the National Institute on
Alcoholism and Alcohol Abuse (NIAAA) are currently underway that will provide
additional data on the effectiveness of this approach. This chapter provides an
overview of the theory of social norms, a brief history, reviews relevant
research, presents evidence of successful outcomes, and concludes with a
discussion of challenges and emerging issues.
The Theory of Social Norms
Social
norms theory describes situations in which individuals incorrectly perceive the
attitudes and/or behaviors of peers and other community members to be different
from their own when in fact they are not. This phenomenon that has been called “pluralistic
ignorance” (Miller & McFarland, 1991; Toch & Klofas, 1984). These
misperceptions occur in relation to problem or risk behaviors (which are
usually overestimated) and in relation to healthy or protective behaviors
(which are usually underestimated). One of the effects of pluralistic ignorance
is to cause individuals to change their own behavior to approximate the
misperceived norm. This in turn can cause the expression or rationalization of
problem behavior and the inhibition or suppression of healthy behavior. This
pattern has been well documented for alcohol, smoking, illegal drug use, and a
variety of other health behaviors and attitudes, including prejudice. In the
case of ATOD use, perceiving the norm to be more permissive than it really is
can facilitate increased use and provide a rationalization for problem users to
justify their
own abuse. The literature on social norms and the supporting research has been
thoroughly reviewed by Berkowitz (2003A) and Perkins (2002, 2003A). Most
of the research conclusions in this chapter are based on the evidence presented
in these literature reviews.
College student use of alcohol can provide a case example. There is
extensive research suggesting that most college students overestimate the
alcohol use of their peers (i.e., there is pluralistic ignorance with respect
to alcohol use. This overestimation results in most moderate or light-drinkers consuming
more than they would otherwise and may also encourage non-users to begin
drinking.
Heavy users of alcohol are even more likely to believe in this
misperception and use it to justify their heavy drinking. This latter case is
an instance of “false consensus” (i.e. falsely believing that others are similar
when they are not). The extent to which alcohol use is misperceived has been
strongly correlated with heavy drinking in many studies. Similar patterns have
been documented for tobacco use.
False consensus and pluralistic ignorance are mutually reinforcing and
self-perpetuating. In other words, the majority is silent because it thinks it
is a minority, and the minority is vocal because it believes that it represents
the majority. Providing accurate normative feedback is one way to break this cycle,
which can otherwise create a self-fulfilling prophecy (i.e., everybody drinks
more because everybody thinks that everybody drinks more).
Social norms theory predicts that interventions to correct
misperceptions by revealing the actual, healthier norm will have a beneficial
effect on most individuals, who will either reduce their participation in
potentially problematic behavior or be encouraged to engage in protective,
healthy behaviors. Thus, information about healthy drinking norms and attitudes
will encourage most individuals to drink less or not at all (which is more
consistent with their underlying values and intentions), and also challenge the
reasoning that abusers use to justify their drinking.
All individuals who misperceive contribute to the climate that allows
problem behavior to occur, whether or not they engage in the behavior. Perkins
(1997) coined the term “carriers of the misperception” to describe these
individuals. Thus, social norms interventions attempt to correct the misperceptions
of all community members whether they actually engage in the problem behavior
or not.
Social norms theory can also be extended to situations in which
individuals refrain from confronting the problem behavior of others. Thus,
individuals who underestimate the extent of peer discomfort with problem
behavior may refrain from expressing their own discomfort with that behavior.
If the actual discomfort level of peers is revealed, these individuals
may be more willing to confront the perpetrator(s) of the behavior. Recent
research on homophobia, for example, suggests that most college students
underestimate the extent to which their peers are intolerant of homophobic
remarks (Bowen & Bourgeois, 2001; Dubuque et al, 2002) and may be willing
to confront these remarks when made aware that peers also feel uncomfortable
(Berkowitz 2002A; 2003B.) Similarly, men underestimate other men’s discomfort with
sexist comments about women and are more willing to confront perpetrators when
they believe that other men feel the same way (Fabiano, et al, submitted for
publication).
The term “social norms” as used here must be distinguished from public
health approaches that attempt to “change social norms.” In this chapter, the
term “social norms approach” refers to the correction of misperceptions of
social norms rather than attempts to change norms when the majority of a
population already behaves in a healthy manner and/or has healthy attitudes.
Thus the goal is to reveal and enhance already existing healthy norms that have
been underestimated and weakened.
While there may also be social and public health issues for which actual
norms need to be changed, this is not what is meant by the use of the term
“social norms” here. Because both meanings of “social norms” are widely used
and have different connotations they must be carefully distinguished because they
refer to different phenomenon and presuppose different models of change.
The assumptions of social norms theory are presented in Table 1.

Individuals passively accept misperceptions rather than actively

or beliefs.

The effects of misperceptions are self-perpetuating, because they
discourage the expression of opinions and actions that are falsely believed
to be non-conforming, while encouraging problem behaviors that are falsely
believed to be normative.

Appropriate
information about the actual norm will encourage individuals to express those
beliefs that are consistent with the true, healthier norm, and inhibit
problem behaviors that are inconsistent with it.

Individuals who do not personally engage in the problematic behavior
may contribute to the problem by the way in which they talk about the
behavior. Misperceptions thus function to strengthen beliefs and values that
the “carriers of the misperception” do not themselves hold and contribute to
the climate that encourages problem behavior.

For a norm to be perpetuated it is not necessary for the majority to
believe it, but only for the majority to believe that the majority believes
it.

The social norms approach integrates a variety of concepts and
phenomenon that have been well documented in the social science literature. For
example, the social psychological phenomenon of “pluralistic ignorance” and
“false consensus” have been extensively studied and provide a coherent explanation
of why individuals act differently from how they feel (in the case of
pluralistic ignorance) or rely on a self-serving bias like false consensus to
justify problem behavior. Social norms interventions can also be understood in
terms of cognitive dissonance theory, another well-established framework within
the social science literature. Providing accurate information about norms
creates cognitive dissonance by informing those who are “in the misperception”
that what they believe is wrong, i.e. that those who are pluralistically
ignorant are in the majority and that those who are in false consensus are in
the minority. Introducing cognitive dissonance can catalyze a process of change
if information about the true norm is introduced in a way that is believable
and credible. Social normsrelies on indirect methods of persuasion that provide
accurate information about what people think or do without telling them what
they should do. The information provided helps the recipient to act differently
without feeling that this change is being imposed from without. This
methodology is consistent with a variety of social psychological approaches to
change that have been empirically supported (Kilmartin, 2003).
A History of the Social Norms Approach
The
social norms approach was first suggested by myself and H. Wesley Perkins based
on research conducted at Hobart and William Smith Colleges in the 1980’s
(Berkowitz & Perkins, 1987, Perkins and Berkowitz, 1986), although it was
initially referred to by different names. It has since been implemented at all
levels of prevention: primary or universal with entire campus or community populations,
secondary or selective with particular subpopulations (such as Greeks and
athletes) and tertiary or indicated with individuals. These approaches use a
variety of methodologies to provide normative feedback as a way of correcting
misperceptions that influence behavior.
The
first social norms intervention was initiated in 1989 by Michael Haines at
Northern Illinois University (Haines, 1996; Haines & Barker, 2003; Haines
& Spear, 1996). Haines expanded on the theory of social norms by applying
standard social marketing techniques to present the actual healthy norms for
drinking to students through specially designed media. This approach has been
called “social norms marketing” (SNM) to distinguish it from traditional social
marketing, which does not contain information about
actual norms. The social norms marketing campaign at NIU is an excellent
example of universal prevention, because it reached the entire population of a
community. It has been in existence since 1989 and has produced significant
increases in the proportion of students who abstain (from 9% in 1989 to 19% in
1998), and in the proportion of students who drink moderately (from 46% in 1989
to 56% in 1998) and a decrease in the proportion of students who drink heavily
(from 45% in 1989 to 25% in 1998), as reported by Haines and Barker (2003).
The NIU intervention was followed by campaigns with equally impressive
results at the
University of Arizona (Glider et al, 2001; Johannessen et al 1999;
Johannessen & Glider, 2003),
Western Washington University (Fabiano, 2003), Hobart and William Smith
Colleges (Perkins & Craig, 2002, 2003A), Rowan University (Jeffrey et al,
2003) and later at dozens of institutions of higher education around the United
States and in a number of high schools as well. On these campuses reductions in
high-risk drinking of 20% or more were achieved within one-two years of
initiating a media campaign. Since then successful social norms marketing
campaigns have been conducted for tobacco (Haines, Barker & Rice, 2003;
Hancock & Henry, 2003; Hancock et al 2002; and Linkenbach & Perkins,
2003A), in a state-wide media campaign (Linkenbach, 2003), and with promising
results for sexual assault (Bruce, 2002; White, Williams & Cho, 2003).
Other social norms marketing campaigns have focused on particular groups of
students (such as athletes or Greeks) rather than an entire campus population.
The websites of the National Social Norms Resource Center (www.socialnorm.org) and the Higher
Education Center (www.edc.org/hec) contain numerous examples of successful social
norms campaigns and the media used to present actual norms.
Concurrent with the development of social norms marketing campaigns,
targeted social norms interventions utilizing interactive workshops in small
groups were being developed. This approach was conceived in the late 1980’s by
Jeanne Far and John Miller at Washington State University, who developed a
protocol for providing normative feedback to groups in an interactive talk show
format (Far, 2001; Far & Miller, 2003). “The Small Group Norms Model”
(SGNM) was offered to a variety of student groups, including sororities and
fraternities, athletic teams, first year students in orientation seminars and residence
halls, and students in academic classes. Far and Miller’s research suggests
that this methodology is more effective in pre-existing groups where group
norms are relevant to the individual, rather than in ad-hoc groups such as
classes and some living units. They reported significant reductions in student
misperceptions of drinking frequency and quantity that were correlated with
actual decreases in drinking among Greeks and in the general campus population
(Far & Miller, 2003) as a result of SGNM.
A
third type of normative intervention is to provide feedback to a single
individual. The initial research on using normative feedback as an indicated or
tertiary intervention was conducted by Alan Marlatt and his colleagues at the
University of Washington and Gina Agostinelli and William Miller at the
University of New Mexico using motivational interviewing and stages of change
theory as a framework. They have developed standardized protocols for providing
individual feedback that can be administered by trained clinicians, peers,
and/or in interactive computer sessions. One of these, the Alcohol Skills
Training Program (ASTP), has been extensively researched with well-documented effectiveness
(Dimeff, et al, 1999; Marlatt & Baer, 1999), confirming that providing
normative feedback to individuals is an essential ingredient contributing to
the success of individual interventions.
A
recent study suggests that providing individualized normative feedback by
itself, without the other components of ASTP, may be equally effective
(Neighbors & Lewis, 2003).
Research on Social Norms
Documentation of Misperceptions. Misperceptions have been documented in over
forty-five studies published in refereed journals (see Berkowitz, 2003A for a
detailed list of these studies).
Alcohol
use misperceptions have been found in studies with small samples of college
students from an individual campus, in larger surveys of individual campus
populations, in multiple campus studies analyzing data from the CORE survey and
the College Alcohol Study, and among middle and highschool students, and young
adults not in college. Some of these studies are also discussed in recent reviews
by Perkins (2002, 2003A).
Misperceptions
of alcohol use are held by all members of campus communities including undergraduate
and graduate students, faculty and staff, students and student leaders.
Researchers have also reported misperceptions for DWI (driving while
intoxicated) and RWID (riding with someone who is intoxicated).
Other
studies have reported misperceptions for cigarette smoking and for marijuana
and other illegal drug use. In addition to alcohol, tobacco and other drugs,
misperceptions have been documented for homophobia, attitudes about sexual
assault, gambling, and eating behaviors in studies reviewed by Berkowitz
(2003B).
Misperceptions
are formed when individuals observe a minority of individuals engaging in highly visible problem behavior (such as
public drunkenness or smoking) and remember it more than responsible behavior
that is more common but less visible (Perkins, 1997). These misperceptions are assumed
to be normative and are spread in “public conversation” by all community
members (Perkins, 1997).
Misperceptions
have been found among fraternity members, athletes, student leaders, among students
of different religious backgrounds, and may vary by gender. In addition there
are over fifteen studies of pluralistic ignorance documenting misperceptions
for topics such as white’s attitudes towards desegregation, gang behavior, and
student radicalism (see Miller and McFarland, 1991 and Toch & Klofas, 1984
for reviews of this literature).
Table
2 contains a summary of studies documenting misperceptions, listed by topic and
population.
(Insert
Table 2 Here)
Which
Norms Are Salient? Individuals have friends, are members of groups, may live in
residence halls, and are part of a larger community. Each of these overlapping
groups have norms that may be similar or different, and some or all of these
norms may exert an influence on an individual’s behavior.
Thus,
one critical issue is to evaluate the relative strength of these different
norms. For example, on most campuses students have a general idea of the
“average” student and are influenced by this cam norm (Perkins, 2003B) even
when the norms of friends and more immediate groups are more influential. In
other cases, group identity may supplant campus or community identity,
especially if the community is very heterogeneous or diffuse (for example, on a
commuter campus).
Misperceptions
increase as social distance increases, with most individuals perceiving that friends
drink more than they do and that students in general drink more than their
friends (see Berkowitz, 2003A for a summary of this research). Among college
students, others in a living unit are thought to drink more than friends but
less than students in general, and students who live together tend to develop
similar patterns of misperceptions over time (Bourgeois & Bowen, 2001).
Misperceptions thus tend to increase as social distance from the misperceiver
increases, but social groups that are “closer” are more influential in shaping
behavior. This leads to the question of whether closer “local” norms of a group
or more distant “global” campus norms should be addressed in designing an intervention.
In most cases both can be addressed together through a combination of primary
and secondary prevention strategies such as small group norms interventions and
campus-wide social norms media campaigns. Selecting the most relevant and
salient norms for a particular intervention and the appropriate strategy for
changing those norms should be an integral part of planning a social norms intervention.
Do Misperceptions Predict Behavior? There are at least fifteen published
studies in which misperceptions are positively correlated with drinking
behavior or predict how individuals drink.
In
a study by Perkins and Wechsler (1996), perceptions of campus drinking climate
explained more of the variance in drinking behavior than any other variable.
Similarly, Clapp and McDonnell (2000) found that perceptions of campus norms
predicted drinking behavior and indirectly influenced drinking-related
problems. In a number of other studies, misperceptions predicted alcohol use
and/or problem use (Beck and Trieman, 1996; Korcuska & Thombs, 2003;
Perkins, 1985, 1987; Thombs, Wolcott and Farkash, 1997; Trockel, Williams and
Reis, 2003). Similarly, Page, Scanlan and Gilbert (1999) found that
overestimations of binge drinking were directly correlated with rates of binge drinking.
In other studies examining drinking behavior over time, perceptions of drinking
norms at time
one predicted drinking behavior at time two (Sher et al, 2001; Prentice and
Miller, 1993; Steffian,
1999)
In
studies of high school and middle school populations, perceptions of norms have
accurately predicted behavior change at a later point in time (D’Amico et al,
2001; Botvin, et al, 2001; Marks, Graham & Hansen 1992). Finally, Thombs
(1999) tested four different models of driving while intoxicated (DWI) or
riding with someone who was intoxicated (RWID), and found that misperceptions for
DWI and RWID had the greatest predictive value in explaining both DWI and RWID.
These
studies are listed in Table Three.
(Insert
Table Three Here)
In
summary, a substantial body of research suggests that misperceptions exist,
that misperceptions are associated with increased drinking or other problems,
and that problem behavior is often best predicted by misperceptions of
attitudes/or and behaviors. This includes correlational studies, longitudinal
studies, and outcome studies with experimental and control groups.
Successful Interventions Utilizing the Social Norms
Approach
As mentioned earlier, social norms theory can be used to develop
interventions that focus on three levels of prevention specified as universal,
selective, and indicated (Berkowitz, 1997). Universal prevention is
directed at all members of a population without identifying those at risk of
abuse.
Selective prevention is directed at members of a group that is at risk
for a behavior. Indicated prevention is directed at particular
individuals who already display signs of the problem. Interventions at all
three levels of prevention can be combined and intersected to create a
comprehensive program that is theoretically based and has mutually reinforcing
program elements. Interventions in each of these categories are reviewed below.
Universal Prevention – Social Norms Marketing Campaigns. A number of campuses have
successfully reduced drinking by developing campus-wide electronic and/or print
media campaigns that promote accurate, healthy norms for drinking and non-use.
These include Western Washington University (Fabiano, 2003), the University of
Arizona (Glider et al, 2001, Johannessen & Glider, 2003; Johannessen, et al, 1999), Northern Illinois University
(Haines, 1996; Haines & Barker, 2003; Haines & Spear, 1996), Hobart and
William Smith Colleges (Perkins & Craig, 2002, 2003A) and Rowan University
(Jeffrey et al, 2003). These campaigns use social marketing techniques to
deliver messagesabout social norms. At these schools, a reduction of 20% or
more in high risk drinking rates occurred within two years of initiating a
social norms marketing campaign, and in one case resulted in reductions of over
40% after four years. Haines, Barker and Rice (2003) reported similar results
for both tobacco and alcohol in social norms marketing campaigns conducted in
two Mid-western high schools. In all ofthese campaigns, positive changes in
behavior were associated with correction of misperceptions over time. In
addition, efforts in past years using other approaches to drug prevention did
not result in any behavior change.
The website of the Social Norms Center (www.socialnorm.org) presents data
from these and other schools. Monographs developed by Haines (1996), Johannesen
et al (1999), and Perkins and Craig (2002) and chapters by Fabiano (2003) and
Linkenbach (2003) outline the stages of developing a social norms marketing
campaign, offer guidelines for creating effective media, and present
evaluationdata in support of the effectiveness of social norms marketing
campaigns.
Perkins and Craig (2002) conducted the most thorough and comprehensive
evaluation of a social norms marketing campaign. Their intervention combined a
standard poster campaign with electronic media, an interactive web site, class
projects that developed parts of the campaign, and
teacher training for curriculum infusion. It was begun in 1996 at a
college with higher than averagealcohol use. Multiple evaluations that were
conducted determined that: 1) increases in drinking that normally occur during
the freshman year were reduced by 21%; 2) previous weeks’ high risk
drinkingdecreased from 56% to 46%; and 3) alcohol-related arrests decreased
each year over a four-year timeperiod. Corresponding reductions were also found
in misperceptions of use, heavy drinking at a party, and negative consequences
associated with alcohol use. Surveys conducted at three time periods over a five-year
period indicate successive linear decreases in all of these measures over time.
More recently, social norms marketing campaigns have been successful in
reducing smoking prevalence and delaying smoking onset. For example, in a seven
county campaign directed at 12-17 year olds in Montana, only 10 percent of
non-smokers initiated smoking following the campaign, while 17 percent in the
control counties began smoking, a 41% difference in the proportion of teens
initiating smoking in the intervention counties as compared with those in the
rest of the state (Linkenbach & Perkins, 2003A). Another study at the
University of Wisconsin-Oskosh reported a 29% decrease in smoking rates as a
result of a multi-component intervention, while rates at a control campus
remained unchanged (Hancock, et al, 2002). Finally, at Virginia Commonwealth
University cigarette use remained stable as perceptions became more accurate
while the number of cigarettes smoked permonthat a control campus increased
(Hancock et al, 2002; Hancock & Henry, 2003). These tobacco studies provide
strong support for the effectiveness of social norms campaigns for smoking, and
their use of control groups strengthens the scientific literature in support of
the model. Hancock et al (2002) discussed the differences between smoking and
alcohol use behaviors that need to be considered when designing a social norms
marketing campaign for smoking.
Table three provides a summary of these social norms marketing
campaigns.
(Insert Table Four Here)
In summary, these interventions using social norms marketing provide
strong evidence that the social norms approach can be effectively applied as a
universal prevention strategy for alcohol to reduce high-risk drinking and
promote moderate use, and for smoking to reduce smoking prevalence and delay
its onset.
Selective Prevention – Targeted Social Norms Interventions. Targeted interventions
focus on members of a particular group, such as first-year students, fraternity
and sorority members, athletes, or members of an academic class. In most of
these campaigns information about the actual norms for the group are provided
in small interactive group discussions, workshops, or academic classes. Due to their
smaller size and more manageable format, many of these interventions have been
evaluated using control groups.
Successful targeted small group norms interventions have been reported
by Schroeder &
Prentice (1998), and by Barnett, et al, (1996), Far & Miller (2003),
and Peeler et al (2000) using the SGNM. Steffian (1999) compared a small group
norms approach for alcohol abuse prevention with a traditional alcohol
education program and found that “changes in normative perception were among
the strongest contributors to a function discriminating between those who
decreased their drinking and those who did not.”
Social norms messages have also been integrated into interactive peer
theater performances, with significant reductions in the frequency of use, DWI,
and regretted behavior, and corresponding increases in protective behaviors in
comparison with a control group (Cimini, Page & Trujillo, 2002).
Other selective interventions have utilized more focused media campaigns
directed at a particular group of students in combination with other
strategies. For example, the University of Virginia designed a targeted social
norms marketing campaign for first-year students. Over a period of three years
the number of drinks per week for first-years went down from 3 drinks a week to
1, the median number of drinks per week for Greek first year men went down from
15 to 7, and the percentage ofabstainers went up from 35% to 49% (Bauerle,
2003; Bauerle, Burwell & Turner, 2002).
At Rochester Institute of Technology a social norms marketing campaign
was developed for Deaf and Hard-of-Hearing students to reduce the incidence of
sexual assault (White, Williams, & Cho, 2003). The tailored campaign was
successful in changing attitudes and perceptions, and resulted in fewer sexual
assaults.
These examples provide strong support for the effectiveness of selective
social norms interventions directed at particular groups of at-risk students
when used alone or in combination with other strategies. Targeted social norms interventions
such as these appear to be more effective when the normative data are tailored
to the group in question and when they are presented in more extended, interactive
formats.
Indicated Prevention (Individualized Social Norms Interventions.) Normative data
about drinking can be presented to high-risk drinkers and abusers as part of
individual counseling interventions. Since abusers tend to adhere strongly to
misperceptions that serve to rationalize their abuse, providing individualized
normative feedback is a non-judgmental way to create cognitive dissonance in
heavy drinkers and catalyze change. Alan Marlatt and his colleagues at the
University of Washington (Dimeff, et. al. 1999) developed the Alcohol Skills
Training Program (ASTP), an eightsession motivational interviewing approach
based on stages of change theory to provide heavy drinkers with non-judgmental
feedback about their drinking indicating that it is much more extreme than that
of peers on a variety of measures. ASTP has been condensed into both a one-hour
intervention (BASICS) and a correspondence course in which subjects use a
manual. All three interventions have been successful in reducing drinking at
follow-ups as long as 1-2 years (Dimeff, et. al. 1999; Larimer & Cronce,
2002), including with high-risk drinkers (Murphy et al 2001).
Agostinelli, Brown & Miller, 1995 were able to produce similar
reductions in drinking by mailing participants personalized graphic feedback
following their completion of a mailed survey. Similar results were found in a
larger population study, in which a normative feedback pamphlet was mailed to over
6,000 households, with respondents in households receiving normative feedback
reported significantly lower alcohol use than controls (Cunningham et al.
2001).
High-risk drinkers and smokers have also been influenced by campus-wide
media campaigns.
Thus, in studies mentioned previously, Perkins and Craig (2002) reported
four-fold reductions in the typical increase in high-risk drinking among
first-year students and a 21% reduction in weekly heavy drinking, and a
University of Wisconsin campaign resulted in a 29% decrease in smoking rates in
one year. As noted earlier, social norms interventions at Washington State
University (Far & Miller, 2003) and the University of Virginia (Bauerle,
Burwell & Turner, 2002) have also been successful in reducing high-risk
drinking.
In summary, norms corrections interventions with heavy drinkers are
theoretically sound and can
be effective both in individual contexts as part of a motivational
interviewing strategy or as part of campus-wide media campaigns.
Emerging Challenges and Issues
As noted above, interest in the social norms approach is growing,
research continues to validate the theory, and new applications are being
developed in a variety of areas. With this growth and expansion and the
enthusiasm that accompanies it are a number of challenges. In particular, it is
important to learn from unsuccessful interventions along with the numerous and
growing examples of success. These failed interventions can be very instructive
and serve to articulate, refine, clarify and expand the model. Because most of
these failures may be due to lack of fidelity to the model, it is important to
consider the following challenges:
Developing the necessary infrastructure to support a social norms
campaign (i.e. “readiness”). The theory of social norms makes intuitive sense to
many prevention specialists in contrast to other approaches which may have
failed to produce results. Yet while the theory is elegant, implementation is
difficult and requires a significant amount of “readiness” or preparation to
ensure that an infrastructure is available that can deliver a quality
intervention. Johannessen and Dude (2003) reviewed elements of readiness that include:
1) training key stakeholders and staff in the model, 2) creating support and
discussion in the larger community, 3) revising policies that may foster misperceptions,
4) collecting and analyzing data, and 5) training and supporting project staff
to implement the model properly.
Deciding which messages are appropriate and relevant for which audience
(salience). In
relatively homogeneous communities, all members may feel a part of the
community and react positively to a community norms-based message. Many social
norms marketing campaigns adopt this format with slogans such as “most of us”
or “students at our university…” However, in a very heterogeneous community
students may not identify with messages like these unless they are carefully constructed
to have broad appeal. Some students may identify more with particular
identities such as participation in a sport or affinity group and be better
reached through these channels. Thus, which messages are “salient” to which
groups is an important consideration in social norms campaigns.
Creating credible messages in terms of message, source, and explanation
of data (believability). Social norms messages contradict widely held beliefs and introduce
cognitive dissonance by suggesting that the truth is different from what is
popularly thought. Ideally, these messages will stimulate a process of
self-reflection and re-examination of what is normative. However, when a
message is not believed and easily rejected, a campaign is compromised. This
can be due to a variety of factors, including when the source of the message is
not trusted, the presentation of the message is not appealing, or data that is
questioned is not explained thoughtfully. Granfield (2002) has provided a case
study of a social norms campaign in which issues of believability initially
undermined the campaign.
Making sure that program evaluations are thorough and reveal any
successes (evaluation). Kilmer and Cronce (2003) have suggested that inadequate evaluation of
social norms campaigns may lead to the incorrect conclusion that they have not
been successful when in fact positive changes have been overlooked. Thus, while
the overall percentage of students who drink less than a certain amount may
remain unchanged, beneficial changes can occur within this group. Similarly, some
groups may be positively affected while others are not. Finally, methodological
difficulties in evaluation design may obscure positive changes.
Responding to critics. The social norms approach has met with criticism
from some individuals. Berkowitz (2002B), Perkins (2003B) and Rice (2002) have
provided detailed responses to a variety of criticisms. They suggest that
critics may be holding the social norms approach to a higher standard of
evidence and implementation than other approaches, and that many of the
complaints are based on misunderstandings, or lack of familiarity with the
research.
Issues of replicability. Social norms campaigns are context specific. Thus,
a particular message or style of media presentation may be appealing in one
community and not in another. In addition, the best means of disseminating
information may differ among groups or communities.
Because of this context issue, attempts to
replicate social norms interventions independent of a specific context may fail.
Similarly, when a social norms intervention is adapted to a different health
issue, the intervention must be tailored to the culture of the new problem.
Combining Social Norms with Other Approaches to Drug Prevention. There is currently no
consensus regarding whether social norms is effective when combined with other
drug prevention strategies – particularly environmental management. At a
minimum, other strategies and methodologies that foster fear and call undue
attention to extreme behavior should be minimized because they will undermine
social norms efforts and have not been found to be effective. Some experts
argue that social norms and other environmental management strategies can be
effectively combined, while others argue that the desired changes can be
created through social norms alone.
In summary, as the social norms approach has evolved a variety of issues
and concerns have surfaced at the same time as new successes are reported. It
is important to consider to what extent an intervention is faithful to the
model when evaluating it and to address the factors noted above.
Conclusion
The social norms approach has met with considerable success in
preventing alcohol and tobacco use and abuse since it was proposed over fifteen
years ago by H. Wesley Perkins and myself.
Successful social norms programs have been developed
for universal, secondary, and indicated prevention, and applications have been
tested for a variety of other issues. The social norms approach provides an
excellent example of how theory and research driven interventions can be
designed, implemented, and evaluated to address health problems. Finally, it
represents a paradigm shift in which the underlying health of a community is
emphasized and enhanced, in contrast to traditional to fear-based messages that
focus exclusively on the problem.
