Presentation Outline

What are we trying to communicate, to whom?
•
•
•
What are we trying to change?
What are we up against?
Three lessons learned
1. Education and awareness may not be enough
2. Connect messages to broader values
3. Opposing messengers are a challenge
• Some concluding thoughts
Traditional Health Communication
• Focus has largely been on
changing individual behavior,
BUT…
• Behaviors and health outcomes
are largely shaped by larger social,
political, economic environments
• Need different message
strategies, may be at odds with a
focus on individual behavior
Features of Many Health Issues
• Strong sense of personal responsibility for health in
public opinion and discourse

• Powerful industries promoting health-harming
products, incredible $ resources to fight regulation

What are the Targeted Outcomes for Effective
Communication about Population Health?
1. Increase awareness of health disparities
2. Increase belief that disparities are worth addressing
3. Heighten belief that societal forces and actors cause,
and are responsible for, poor health and disparities
4. Promote support for policies with potential to
improve social determinants and reduce disparities
5. Mobilize action to advocate for social change
Lesson 1:
Raising Awareness is Not Sufficient
Lesson 1:
Raising Awareness is Not Sufficient
• Priming group differences
Priming Group Differences
• Public support for government intervention
depends on type of group difference
– Economic disparities: greatest support
– Racial disparities: least support
• Perceptions of the causes of group
differences matter
– Relates to underlying attitudes about causality,
responsibility, and fairness
– Behaviors vs. social structure vs. genetics
Sources: Rigby et al. (2009); Lynch & Gollust (2010)
Lesson 1:
Raising Awareness is Not Sufficient
• Priming group differences
• Pre-existing awareness and values lead to “biased
processing”

Biased Processing of SDH Messages
• Focus group insight
• Without concrete mechanisms for how SDH produce
disparities, people fill in the blanks with preconceptions
• In response to a chart showing the bivariate association
between education and life expectancy:
“Maybe somebody didn’t go on to school or even didn’t
finish high school but they might have gotten a good
education at home in terms of how to be a healthy person.”

Lesson 2:
Connect Messages to Larger Values
Lesson 2:
Connect Messages to Broader Values
• Acknowledge personal responsibility
– BUT…
• Proceed with caution
MALL EXPERIMENT
Insights from Mall Experiment
•
Methods
• 500 participants, 4 conditions, summer 2010
• Michele’s story – environmental and economic
causes of obesity, neighborhood development as
an effective solution

MALL EXPERIMENT
Insights from Mall Experiment
•
Methods
• 500 participants, 4 conditions, summer 2010
• Research Question:
• How strongly should a story emphasizing SDH as
causes and solutions for obesity
• Acknowledge personal responsibility
• To increase complexity of thinking about obesity’s
causes, and
• Maximize support for obesity policies?
MALL EXPERIMENT
Example of Condition Differences
•
High Responsibility
•
•
Moderate Responsibility
•
•
Here, she feels comfortable getting out of the house and exercising
outside – activities Michele sees as tremendously important for improving
her health. This has helped Michele to develop healthier lifestyle habits.
Here, she feels more comfortable getting out of the house and getting
outside. This has helped Michele to have more options for improving her
health – even though following through on them is a challenge.
Low Responsibility
•
Here, she feels more comfortable getting out of the house, even if she’s
not intending to exercise.

… BUT Proceed with Caution
• Personal narratives can shift emphasis to individual
responsibility
• Stories about individual children can increase
blame to children for obesity
• Policymakers counterargue individual narratives
unless combined with broader statistics or a story
told about the community

Lesson 2:
Connect Messages to Broader Values
• Acknowledge personal responsibility
– BUT…
• Proceed with caution
• Identify novel values related to population health
improvement to reach broader coalitions

Lesson 3:
Opposing Messages(-ers) are a Challenge
• It can be useful to anticipate and try to offset
counter-arguments from opponents of social change
NATIONAL EXPERIMENT
How tackling opposing arguments can be useful
• Content analysis of arguments used to support
and oppose the tax in public discourse
• Niederdeppe et al., AJPH, 2013
• Public opinion poll gauging response to discrete
pro- and anti-tax arguments
• Barry et al., AJPM, 2013
• In-depth interviews with SSB tax proponents and
advocates in jurisdictions where taxes proposed
• Jou et al., AJPH, 2014
NATIONAL EXPERIMENT
Surveys to Identify Resonant Frames – Pro-Tax
NATIONAL EXPERIMENT
Surveys to Identify Resonant Frames – Anti-Tax
NATIONAL EXPERIMENT
Theoretical Rationale
• Strongest pro-tax arguments focus on:
• Largest driver of obesity (“softening the ground”)
• Provides funds for childhood obesity prevention
• Beverage industry outspends pro-tax advocates by
a large margin; anti-tax arguments resonate strongly
• Inoculation Theory
• Protect from subsequent (persuasive) attack by
highlighting source motives and countering weak
arguments (“industry demonization”)
NATIONAL EXPERIMENT
National Randomized Experiment
• Randomized experiment conducted from OctoberDecember, 2012 using the survey research firm
GfK Group (Knowledge Networks)
• 3,118 completed baseline survey and follow-up

NATIONAL EXPERIMENT
A Strong Pro-Tax Argument
Supporters of a tax say that sugary drinks may be the single largest
driver of obesity in the United States. More children are obese today
than in previous generations. Rates of obesity have tripled among
children and teens over the past 30 years. Children and teens drink
twice as much soda and other sugary drinks as they did 30 years ago.
Supporters of a tax say drinking a 20-oz soda is equivalent to eating
16 packets of sugar. That’s 240 empty calories in a single bottle.
When people consume sugary drinks, they do not feel full, so they
tend to eat more food. Children who drink sugary beverages also
prefer foods with higher calories, leading to worse overall nutrition.
NATIONAL EXPERIMENT
A Strong Anti-Tax Argument
Opponents of a tax say obesity is a matter of how many calories
people consume, not where those calories come from. A tax on
sugary drinks is arbitrary because it does not affect other unhealthy
foods like donuts, cookies, and candy bars.
Obesity is a complex problem that cannot be solved by focusing on
just one small part of a person’s diet. Sugary drinks account for only
7 percent of calories in the average American's diet. Science shows
that obesity is caused by an imbalance between the calories we
consume through food and drinks and those we burn through daily
activities and exercise.
NATIONAL EXPERIMENT
Inoculation Treatment
Soda companies will try to convince you that a tax on sugary drinks
is arbitrary because it does not affect foods like donuts, cookies, and
candy bars. They will say that they are an unacceptable intrusion of
government into people’s personal choices. They will call them “food
taxes” to try to confuse people.
But sugary drinks are not food – they have no nutritional value. In
fact, research suggests that sugary drinks are the single largest
driver of obesity in the United States. Nobody is telling anyone what
to drink. But, by adding a few pennies to the price of a soda, many
people will choose differently.

Some Concluding Thoughts
Also Need to Consider:
Who Delivers the Message?
• Traditional news
Traditional news
• Growing capacity to cover disparities, but
• Covering them is still relatively uncommon
Also Need to Consider:
Who Delivers the Message?
• Traditional news
• Novel messengers
Novel Messengers
• Violating expectations of a source can be powerful
• Partisan labels increase policy support when they
take an unexpected position on a partisan issue
• E.g., Republican endorsing same-sex marriage
• E.g., Democrat opposing abortion rights
Source: Bergan (2012)
Novel Messengers
Military
leaders
speaking to
policymakers
and the public
“When it comes to children’s health and our
national security, retreat is not an option.”
“Retreat is Not an Option: Healthier School
Meals Protect Our Children and Country”
What We Need to Know
• Need more work on the messenger
• Need more work on actions vs. opinions/perceptions
– What are the actions that individuals can take to influence
policy?
