Health promotion - Psychology (9990) - Cambridge International AS Level

Welcome to Health Promotion!

Ever wondered why some TV adverts try to scare you into quitting smoking, while others just give you facts? Or why your school used to give out stickers for eating vegetables? That is what Health Promotion is all about! In this chapter, we explore the different ways psychologists try to "nudge" people into living healthier lives.

Don't worry if some of the study names sound a bit long—we are going to break them down into simple stories. Let’s dive in!

1. Strategies for Promoting Health

Psychologists have different "tools" in their kit to convince people to change their habits. Two of the main ones are Fear Arousal and Providing Information.

Fear Arousal: Janis and Feshbach (1953)

The idea here is simple: if you scare someone enough, they will change their behavior to avoid the danger. But does it actually work? Janis and Feshbach tested this using dental hygiene (tooth brushing).

They showed high school students three types of presentations:
1. High fear: Showed "gross" pictures of diseased mouths and warned of painful infections.
2. Moderate fear: Less "gross," described dangers but in a milder way.
3. Low fear: Just gave a lecture about tooth decay without the scary stuff.

The Results (The "Fear Paradox"):
Surprisingly, the low-fear group changed their behavior the most! The high-fear group felt too anxious, so they "tuned out" the message to protect themselves.
Analogy: Imagine a horror movie is so scary you cover your eyes—if you cover your eyes, you miss the "message" of the movie!

Providing Information: Lewin (1992)

Sometimes, people just need the right facts presented in the right way. Lewin looked at whether giving patients a "Heart Manual" (a book with information and self-help tips) helped them recover after a heart attack.

What happened?
Patients who got the manual were much less anxious and had fewer visits to the doctor compared to those who just got "standard" medical advice. This shows that empowering people with information helps them feel in control of their own health.

Quick Review: Strategies

• Fear Arousal: High fear can backfire because people ignore it.
• Information: Giving people a "how-to" guide (like a manual) reduces stress and improves recovery.

2. Health Promotion in Specific Places

Instead of just using TV ads, psychologists often go to where people are: Schools and Worksites.

In Schools: Tapper et al. (2003) - The Food Dudes

How do you get kids to eat broccoli? Tapper et al. used a program called "The Food Dudes." It used three main secrets:
1. Role Modeling: Kids watched videos of older "hero" kids (the Food Dudes) eating fruit and veg to gain superpowers.
2. Rewards: If kids ate the healthy food, they got stickers or small prizes.
3. Repeated Tasting: They were encouraged to try things multiple times.

Did you know? This program was so successful that even after the rewards stopped, the kids kept eating more fruit and vegetables because they had developed a taste for them!

In Worksites: Fox et al. (1987) - Token Economies

Promoting health isn't just about food; it's about safety. Fox et al. studied open-cast mines. They used a Token Economy system where workers earned stamps (tokens) for:
• Working without any accidents.
• Being in a group where no one got hurt.
• Suggesting new safety rules.

Workers could trade these stamps for items in a catalog (like a toaster or a radio).
The result: Accidents dropped dramatically, and the company saved thousands of dollars in medical costs!

Key Takeaway: Settings

• Schools: Use "cool" role models and small rewards to change habits (Food Dudes).
• Worksites: Use "tokens" (like points or stamps) to reward safe behavior (Fox et al.).

3. Measuring Health Promotion

How do we know if a big government campaign actually works? We have to measure it! A famous study by McVey and Stapleton (2000) looked at an anti-smoking campaign in the UK.

McVey and Stapleton: Anti-Smoking TV Ads

The researchers compared different regions in England. Some areas saw anti-smoking TV ads, and others didn't (the control group). They wanted to see if the ads made people stop buying cigarettes.

What they found:
• The ads *did* help people quit, but it was a "dose-response" relationship.
• The "Dose": People who saw the ads more often were more likely to quit.
• However, they also found that after the ads stopped, some people started smoking again. This tells us that health promotion needs to be long-term to stick.

Common Mistake to Avoid: Don't assume a campaign is a failure if 100% of people don't quit. In psychology, even a 2% or 3% change in a whole country is considered a huge success!

4. Summary Table for Revision

Use this table to keep the studies straight in your head!

Memory Aid: The "Three R's" of the Food Dudes

If you are struggling to remember how Tapper et al. changed kids' behavior, just remember the 3 R's:
1. Role Models (The Food Dudes heroes).
2. Rewards (Stickers and prizes).
3. Repeated tasting (Trying it until you like it).

Final Quick Review

Health promotion is about using psychology to help people live better. We can scaring them (carefully!), give them manuals, use heroes in schools, or give them tokens at work. To see if it works, we compare groups who saw the campaign against those who didn't.

You've got this! Just remember that health promotion is all about moving from "knowing" what is healthy to actually "doing" it.
