Health awareness campaigns and disease prevention programs can empower individuals to make healthier choices and reduce their risk of disease and disability. At the population level, they can eliminate health disparities, improve quality of life, and improve the availability of healthcare and related services.
A health promotion campaign is more successful if it uses a multi – level approach.
It can influence individuals and groups by having different strategies at different levels.
• Educating individuals about healthy practices
• Changing an organisation or institutions behaviour(healthy eating option)
• Changing the social(no smoking in public places) and physical environment(providing outdoor shelters for smokers)
• Policies to support the changes(smoking ban in public places)
• A range of strategies(policies, television advertisements, leaflets, posters, events, etc. )

There needs to be:
• Increased knowledge
• Motivation
• An environment that will influence the changes needed
• The skills to make the change

The individual/group(the target group) needs to have:
• The self concept factors that will encourage change(belief in themselves, self efficacy)
• The right attitude to want to change
• Knowledge
• Motivation
• Past experience
• The skill
• The belief it will be a change for the better
• Need to have understanding of the threat posed by the health problem(susceptibility, severity)
• The benefits of avoiding the threat
• Need to be aware of the factors that can affect the decision to act(barriers, self efficacy, cues to act)
