Useful Theory: Diffusion of Innovations

brainstorming at a table

Imagine you have come up with an awesome new health literacy initiative. You’ve put in the time planning, developing, and testing it. You’re about to educate hundreds — scratch that — thousands. You can see it catching on: health literacy is taking the world by storm.

Now, how do you make that vision a reality? The truth is that most big ideas don’t make it because more attention is given to creating the ideas than spreading them.

Fear not, health literacy warrior! Look to the Diffusion of Innovations Theory. The theory describes many things, but where we see its value is in explaining how new innovations catch on. Understanding this can help you better promote and market your program.

Use the concepts below when you explain the benefits of your program to the masses. (Don’t be intimidated by the fancy buzzwords!)

  • Relative Advantage: How much better your innovation is than the one it’s replacing
  • Compatibility: How your innovation falls in line with potential users’ experiences and values
  • Complexity (or Simplicity, as we like to say): How easy the innovation is to understand and use
  • Trialability: How easy it is to try out the innovation before committing to it
  • Observability: How easy it is for users (and the people they know) to see results from using the innovation

By using these concepts when you promote your program, you’ll greatly increase the chance that people will give it a try.

The bottom line: When promoting a new idea (like a health literacy program), use the Diffusion of Innovations Theory to increase the chance of it catching on.

Team Plain Language!

2 people exclaim, “It’s a bird, it’s plain language!” while looking at a poster of “Team Plain Language” superheroes: Lois Plain, Captain Clarity, Dejargonizer, The Incredible Bulleted List, Catheadman, and Fred.

As advocates for health literacy and plain language, we need to be ready to respond to a skeptic at a moment’s notice. Are you ready, Team Plain Language? Team Jargon can be intimidating, but with the right tools, we can win!

Every effective advocate has go-to arguments on hand, so we’re sharing a few of our favorites to help you build your arsenal.

  1. Plain language is the law. Since President Obama signed the Plain Writing Act of 2010, many federal agencies began writing more clearly. Similar regulations also apply to credit cards and health insurance.
  2. Simple sells. Many private companies are moving toward using plain language because it increases customer satisfaction. Just think about Apple. Customers (aka most people) are busy — they want to understand things quickly and easily.
  3. Clear communication is more effective. It saves times, cuts down on errors, and helps reduce costs. There are plenty of studies showing the benefits.

Why are you on Team Plain Language? Share your favorite reasons in the comments.

And for a closer look at which federal agencies are excelling at writing in plain language, check out the Federal Report Card from the Center for Plain Language.

The bottom line: Make sure you’re prepared to defend plain language. It’s the law, it’s good for business, and it’s more effective.

How do you explain “contaminated” in plain language?

A doodle in a bubble, among zombies, saying "Wow, it's real unsafe out there!"

If you’re a plain language writer, you may shudder at the word “contaminated.” It’s a word that many audiences struggle to understand, and yet it shows up a lot in environmental health writing.

Typically, the first line of attack when encountering a tough word is to avoid using it altogether. But, in this case, what word can you use instead?

“Polluted” might work, but that’s not particularly plain language either — and sometimes it won’t technically be a correct substitution. And if a consumer has to deal with an ongoing contamination situation, then it can be a term worth knowing. What’s a clear communicator to do?

To best explain this concept to your readers, focus on the outcome: If something is contaminated, what does that mean for them? Usually, the contaminated thing isn’t safe — to eat, drink, use, touch, and so forth. So, contaminated = unsafe.

If you have to write about something that’s contaminated, check out these examples that may make your life easier:

  • The germs contaminated the food (made it unsafe to eat).
  • Community members were concerned about contaminated (unsafe) water.
  • Put the contaminated (unsafe) items in a trash bag right away.

Now, go forth and write about things that are contaminated — with ease and simplicity!

The bottom line: “Contaminated” can be a difficult word, but people may need to know what it means. If you have to use it, define it in parentheses. We like “unsafe.”

Useful Theory: Health Belief Model

2 doodles at a "Free Health Screening" booth say, "Nobody has shown up, what're we doing wrong?" "We need a model!" as a 3rd doodle arrives with a small model ship, saying "Did somebody say model?"

We all know change isn’t easy. So when we want our audiences to change their health behaviors, we can’t rely solely on plain language and human-centered design — we also have to get inside their heads.

Here at We ❤ Health Literacy Headquarters, we often turn to trusted theoretical models to help us understand how and why people change. And today, we’re talking about one of our favorites: the Health Belief Model.

Over 50 years ago, social psychologists wanted to find out why people weren’t participating in programs to prevent or screen for disease. After all, these programs were in everyone’s best interest, right? The Health Belief Model was born from this investigation. It explains the desires and beliefs that make people take action to prevent, screen for, and control disease.

The gist of the model is that a person’s behavior depends on their perceived benefits and barriers (also known as a cost-benefit analysis). Knowing these perceptions can help us anticipate how people will respond to recommended health behaviors.

To make your content more effective, try helping your readers answer these questions — all based on elements of the Health Belief Model:

  • What’s my chance of getting sick?
  • How serious is the potential health problem?
  • What’s in it for me if I change?
  • What are the costs of changing (like an insurance co-pay or the cost of face masks)?
  • Can I actually do the behavior?
  • What will help me remember to do it?

If your content answers these questions, you’ll give your readers the understanding, tools, and confidence they need to make positive, healthy changes.

The bottom line: If you want readers to change their behavior, make sure your health content explains the benefits and barriers to change.

Space: Use It Well

Densely written documents stand in line to enter a "chunking salon." One remarks, looking at a properly chunked document exiting the salon, "Gasp! He's so easy to read!"

This is Episode 1 of our journey into space. For more adventures, check out Episode 2 and Episode 3.

If you’re a health communicator, it’s important to know that space is your friend. Learn to love space. Don’t see it as an area to fill up with content, but rather as an area to show off the content you already have. Use it strategically.

As we’ve said before, dear readers, people are more likely to skip over content that looks overwhelming or hard to read — even if it’s written using simple words. One trick we’ve already shared is picking the right font. Another trick is to leave more space above your headers than below them.

Why is this a helpful technique? Because having more space above a header than below it creates “chunks” of content that are easy to scan, making your content appear more accessible.

If you have an equal amount of space above and below a header, the header will seem to float and your readers won’t be able to quickly associate it with the body text below.

Who needs to get the flu shot?

Everyone age 6 months or older.

When should I get the flu shot?

As soon as possible, usually in the fall.

But if you don’t leave any white space between headers and body text, your readers won’t be able to scan the content quickly.

Who needs to get the flu shot?
Everyone age 6 months or older.
When should I get the flu shot?
As soon as possible, usually in the fall.

If you leave more space above the header than below it, your readers will thank you.

Who needs to get the flu shot?
Everyone age 6 months or older.

When should I get the flu shot?
As soon as possible, usually in the fall.

The bottom line: Make your content look easy to read by leaving more space above headers than below them.

The Skinny on BMI

Doctors looking at a chart.

Most of us public health geeks probably know what a body mass index (BMI) is. As a refresher, it’s a number calculated based on a person’s height and weight. Although it seems like a simple concept, for lots of people, it isn’t.

For starters, it’s a calculation, which means you have to do math. Even if you use the chart that calculates it for you, reading the chart still requires math skills.

Then take its use: health professionals essentially use it as a “red flag” for weight issues. That means when you’re talking about BMI, you’re talking about risk — about what might be true.

And as if that’s not enough, it might not mean anything. That’s right, BMI is an accurate indicator for most — but not all — people.

So you can see, when you take a step back, BMI can be pretty confusing. And you know what else can be confusing? The chart we’re supposed to use to calculate it. Take a look:

BMI Chart

For people who have trouble with numeracy, which is most of us (public health professionals included), this chart is anything but easy to use. The color on this “simple” version helps, but try finding your BMI without touching the screen to follow the row and column — it’s not easy. And this is a simple version!

So the next time you find yourself mentioning BMI in a written material, you might want to make sure you’re explaining how and why BMI is used as a screening tool.

Oh, and let’s redesign that chart!

The bottom line: Proceed with caution when mentioning BMI. Be sure to explain what it means, and what it doesn’t. And don’t rely on your readers being able to understand the chart.

Screening vs. Test: When Do I Say What?

A Jeopardy-style game show host hovers by a nervous contestant waiting to answer "It's a medical test that checks for diseases before symptoms appear."

What’s the difference between a screening and a test? Do you get screened for high blood pressure, or do you get a blood pressure test? Many people think that screening = test and test = screening, but that’s not always true.

A screening is a test, but not all tests are screenings. Are you having flashbacks to algebra yet?

Let’s clarify: A screening is one kind of test. There are also other kinds of medical tests — which is why “screening” and “test” aren’t always interchangeable.

The next time you need to talk about screening tests in a health material, use something like this plain language definition:

Screenings are medical tests that check for diseases before symptoms appear. Screenings help doctors find diseases early, when they may be easier to treat. Regular mammograms or an HIV test are examples of screening tests.

The other 2 kinds of medical tests are:

  • Diagnostic tests, which look for the cause of symptoms (like an X-ray to see if your arm is broken)
  • Monitoring tests, which keep track of disease or recovery (like getting another X-ray after you get your cast off)

Of course, many people just say “test” when talking about any of these procedures — so it’s worth thinking about whether the type of test is need-to-know information for the material you’re writing. If it is, be sure to explain it in plain language!

The bottom line: Be careful when choosing between “screening” and “test.” Screenings are a type of test, but not all tests are screenings.

Other Things We ❤: Health Literacy Online

The guide walks you through the entire user-centered design process — from creating personas to conducting prototype testing. It will help you write for health and behavior change in a way that really gets results.

The bottom line: We’re big fans of Health Literacy Online, and we think you’ll like it, too!

Don’t tell me what I should do.

A concerned doodle stands next to a computer saying "How does my content look, Tone Fixer?" as the tone fixer replies, "You called just in time! This is the worst case of the "Don't shoulds" I've ever seen!"

When writing health information, it’s important to strike a trustworthy and informative tone while remaining positive and supportive. Health writers usually get the trustworthy and informative part down, but we’re often guilty of forgetting about the other half.

Tone is the feeling behind your words, and it’s just as important as the words themselves. Here are 2 rules we follow at We ❤︎ Health Literacy Headquarters to make sure the tone is right:

  • Start with the positive instead of telling your reader “don’t”
  • Throw “should” out of your vocabulary

Think of it this way: Which of these statements motivates you to make your bed?

  • “Don’t be a slob. You should always make your bed.”
  • “Making your bed is an easy way to make your room look tidy — and it only takes a minute!”

Taking “don’t” and “should” out of your writing will help you create friendly content. And when your messages have a friendly and positive tone, readers will be more engaged and motivated — especially if you’re encouraging them to do something new or difficult.

Imagine you’ve just seen your doctor and she’s printed out some follow-up instructions for you that say:

DON’T do any activities that put weight on the injured foot. You should rest. Putting weight on the foot will worsen the injury and slow your recovery.

Although this is perfectly accurate advice, how does it make you feel? Discouraged? Negative? Maybe a little bit like you’ve done something wrong already?

Now consider this alternative:

Be sure to keep weight off your injured foot during your recovery, because the tendon needs rest in order to heal. Choose activities that won’t put weight on your foot.

It’s the same message, but a completely different tone. With any luck, this friendlier take will leave you feeling better — and ultimately increase the likelihood that you’ll follow the instructions.

The bottom line: Write without “don’ts” and “shoulds” to create positive, supportive, and effective health content.
