8.2.2  Types of appeals in health communication

The fear-arousal appeal

This type of message is conveyed to frighten and arouse people into action by emphasising the serious outcome from not taking action. Symbols such as dying people, coffins, gravestones or skulls may be used. Fear-arousal appeals might be effective for a person with little or no schooling. Evidence suggests that mild fear can arouse interest, create concern and lead to behaviour change. However, creating too much fear is not appropriate.

Humour

The message in this type of health communication is conveyed in a funny way such as in a cartoon (Figure 8.3). Humour is a very good way of attracting interest and attention. It can also serve as a useful method to lighten the tension when dealing with serious subjects.

Enjoyment and entertainment can result in highly effective recall and learning. However, humour does not always lead to changes in beliefs and attitudes. What one person finds funny another person may not. Humour should be used sensitively so as not to offend others.

The logical/factual appeal

The message is conveyed to convince people by giving facts, figures and information — for example, facts related to HIV/AIDS, its causes, route of transmission and prevention methods. The logical/factual appeal carries weight with a person of high educational level. Information on its own is usually not enough to change behaviours and various appeals must be tried to see what works (Figure 8.4).

The emotional appeal

The message is transmitted by arousing emotions and feelings rather than giving facts and figures. A poster or leaflet might use this approach by showing smiling babies or wealthy families with a latrine and associating such images to create a positive healthy impression. A less educated person will often be more convinced by simple emotional appeals from people they trust.

One-sided and two-sided messages

One-sided messages only present the advantages of taking action and fail to mention any possible disadvantages — for example, educating mothers only about the benefits of the oral contraceptive pill, but not explaining the side-effects or risks associated with the pill.

Presenting only one side of an argument may be effective provided your audience will not be exposed to different views at other times. However, if they are likely to hear opposing information, such as the side-effects from a drug, they may be suspicious about taking your advice in the future. It is better to be honest. If communication is through mass media such as radio, TV or newspapers, the audience may only grasp part of the message or selectively pick up the points that they agree with.

A two-sided message presents both the advantages and disadvantages of taking action. It is appropriate if:

• The audiences are used to being exposed to different views
• The audiences are literate
• You are face-to-face with individuals or groups: this makes it easier to present both sides and make sure that the audience understands the issues.

Positive appeals and negative appeals

Positive appeals include communications that ask people to do something positive, such as exclusive breastfeeding for your child, or using a latrine. Whereas negative appeals are where the communication asks people not to do something, for example do not bottlefeed your child, or do not defacate in the bush.

Negative appeals use terms such as ‘avoid’ or ‘don’t’ to discourage people from performing harmful behaviours. But most health educators agree that it is better to be positive and promote beneficial behaviours instead of relying on negative appeals.
