Diseased lungs on a cigarette packet. A hospital scene in a television advert. Health campaigns use fear because fear grabs attention. The interesting question for psychology is whether being frightened for thirty seconds actually changes what someone does for the next thirty years.
📘 What you need to know
A fear appeal is a health message that works by making the audience afraid of what will happen if they do not change.
Health promotion aims to give people control over their own health (WHO, 1986) — so a campaign that only frightens people misses its own aim.
Fear appeals work best when the person also believes they can do something about it (self-efficacy).
Tannenbaum (2015) found fear appeals do work on average, and work better with efficacy messages and when susceptibility is stressed.
Fear is extrinsic: it is pressure from outside. That is why it fades.
Most of the factors that decide whether a fear appeal works are outside the psychologist’s control, which limits how useful the strategy is.
Why campaigns reach for fear
Fear is cheap, fast and impossible to ignore. A frightening image on a packet is seen every single time the packet is opened, which no leaflet can match. And fear does something useful: it makes a distant risk feel personal. “Smoking causes lung cancer” is a fact. A photograph of a diseased lung is a threat.
Health promotion, as the World Health Organization set out in 1986, is about enabling people to take control of and improve their own health. Notice the word control. That is the standard a fear campaign has to be judged against, and it is a high bar. Frightening somebody does not hand them control — it can do the opposite.
The problem with turning fear up
You might expect more fear to mean more quitting. It does not work like that. A message that is too gentle gets ignored. A message that is terrifying can also fail, because the person has no way to act on the feeling, so they push it away instead: they stop looking at the packet, they change the channel, they tell themselves their grandfather smoked until he was ninety.
Drawn to show the pattern, not real data. The useful point for an essay is that the tone of the message is itself a variable a campaign has to get right.
If you can only remember one line about fear appeals, make it this one: fear tells someone they have a problem, but it does not tell them they can solve it. The second half is what actually changes behaviour.
What decides whether a fear appeal works
This is the evaluation point examiners want: the strategy depends on variables the health psychologist cannot reach, so a fear appeal on its own is never enough.
Tannenbaum’s 2015 review pulled decades of fear-appeal studies together and found that, overall, they do change attitudes and behaviour. The detail matters more than the headline, though. Fear appeals worked better when the message also told people how to act, when it stressed that the risk applied to them, and they were more effective with women. Fear appeals were also stronger for people who had already been warned personally by a doctor — which is exactly the group for whom the risk has stopped being abstract.
Research-methods point you can reuse: campaigns run on television and social media, so researchers usually have to ask people how much of the campaign they saw. Nobody can remember that accurately, so the measure of exposure is weak, and that lowers the validity of any conclusion about whether the campaign caused the change.
Fear is extrinsic, and that is the deeper problem
Link this back to Topic 7.1. Fear is a push from outside. It works like any extrinsic motivator: strong at first, then it fades. The image on the packet stops being shocking after the fiftieth time you see it. Nothing has changed inside the smoker; only the stimulus has worn out.
A person who quits because they want their own life to be different is intrinsically motivated, and that is what survives a bad week. So the sharpest conclusion you can write is not “fear appeals do not work” — it is that fear appeals may open the door, but something intrinsic has to walk through it.
Worked examples
WORKED EXAMPLE
Explain one limitation of using fear arousal in health promotion. [3 marks]
State it
Fear arousal is an extrinsic motivator, so its effect fades once the frightening message stops being new.
Explain the mechanismRepeated exposure reduces the emotional response, and a smoker who is frightened but does not believe they can quit may avoid the message rather than act on it.
Consequence
Any change is likely to be short-term unless the campaign also builds self-efficacy and support.
Clear limitation, explained and consequencedThree marks, three moves. Do not open with a definition of health promotion — it is not asked for.
WORKED EXAMPLE
To what extent can people only quit an unhealthy behaviour if they are motivated to do so? [15 marks]
An essay this size needs a shape before it needs content. Here is a plan that would score, with one paragraph written out so you can see the level of detail.
Plan
1 Define motivation, intrinsic vs extrinsic. 2 Case FOR: intrinsic motivation predicts lasting change. 3 Case AGAINST: environment, addiction, price, bans also change behaviour. 4 Measurement problems. 5 Judgement.
Sample paragraph — the case against
Motivation is not the only route to quitting. Smoking rates fell in countries that raised taxes, banned indoor smoking and restricted advertising, and those changes act on people who were never motivated to quit at all. Nicotine dependence is physical, so a strongly motivated smoker can still relapse while an unmotivated one who cannot find anywhere to smoke may stop. Motivation therefore looks necessary for lasting change but not sufficient on its own, and not always required for change in the short term.
Judgement to finish on
Motivation matters most for whether a change lasts; circumstances matter most for whether it starts.
Argument, not a list of studies“To what extent” wants a position. Say how far you agree, and why, in the first paragraph and the last.
💡 Exam tip
Use “self-efficacy” by name. It is the single most useful term in this sub-topic.
One named source (Tannenbaum, 2015) plus the WHO aim of health promotion is enough research for most answers here.
Always connect fear back to extrinsic motivation. That is what makes it a motivation answer rather than a health answer.
If a question gives you a source, quote its content in your own words and use it — markers check that you actually used the source.
Long-term effects are almost never measured in these studies. That single sentence is a strong evaluation point.
⚠ Common mix-up
“Fear appeals do not work.” Too strong. The evidence says they work under conditions. Say which conditions.
Confusing fear with susceptibility. Fear is the emotion; susceptibility is the belief that it could happen to you. Campaigns often create the first without the second.
Writing about smoking, not about motivation. The examiner is marking your psychology, not your health knowledge.
Assuming self-report of a campaign is accurate. People genuinely cannot remember how many adverts they saw.
Treating a graphic image as an experiment. Real campaigns have no control group, so causation is hard to claim.
