1. Credibility

• Definition: The degree to which the message to be communicated is perceived as trustworthy by the receiver.
• Health education must be based on facts - consistent with scientific knowledge and compatible with local culture, educational system, and social goals.
• Unless people have trust and confidence in the communicator, no desired action will follow after receiving the message.
• Example (PSM): A health worker educating villagers about ORS (Oral Rehydration Solution) during a diarrhoea outbreak must be seen as a trusted government health worker or doctor. A message from an unknown outsider about "giving sugar-salt water" to a sick child will be ignored or doubted.

2. Interest

• Definition: People are unlikely to listen to things that are not in their interest (psychological principle).
• Health teaching should relate to the "felt needs" of the people - i.e., needs the people feel about themselves.
• Vague slogans like "be healthy" or "eat good food" are useless.
• Health educators must identify the real, felt health needs of the community.
• In India, ~25% of people are illiterate; the educator must first create recognition of needs.
• Example (PSM): In a village where malaria is rampant, the community's felt need is relief from fever. A health educator uses malaria prevention (mosquito nets, eliminating stagnant water) as an entry point - because that is what people are immediately interested in - rather than starting with abstract lectures on vector biology.

3. Participation

• Definition: Based on the psychological principle of active learning - people learn best by being actively involved.
• Health education should encourage people to work actively with health workers to identify their health problems and develop solutions.
• The Alma-Ata Declaration (1978) states: "The people have a right and duty to participate individually and collectively in the planning and implementation of their health care."
• A high degree of participation creates a sense of involvement, personal acceptance, decision-making, and maximum feedback.
• If community participation is not integral, health programmes are unlikely to succeed.
• Example (PSM): In the National Pulse Polio Programme, ASHA workers and local panchayat members are involved in mobilizing parents, setting up booths, and tracking defaulters. This community participation ensures near-100% coverage in their areas.

4. Motivation

• Definition: Awakening the fundamental desire to learn that exists in every person.
• Two types of motives:
  • Primary motives (sex, hunger, survival) - driving forces initiating action
  • Secondary motives (prestige, security, social acceptance) - acquired through learning and experience
• Motivational talks, role models, and incentives are important tools.
• Example (PSM): To motivate mothers to bring children for immunization, health workers explain that the child will be protected from deadly diseases like polio and measles (survival motive). Showing a child crippled by polio in a poster also creates fear-motivation to vaccinate.

5. Comprehension

• Definition: Health education must match the level of understanding, education, and literacy of the target audience.
• Using unfamiliar words is a key barrier to communication.
• Always communicate in the language people understand; never use jargon or strange words.
• Teaching should be within the mental capacity of the audience.
• Classic Park's example: A doctor told a diabetic to "cut down starchy foods" - the patient had no idea what starchy foods were. Another doctor prescribed "one teaspoonful three times a day" to a village woman who had never seen a teaspoon.
• Example (PSM): When educating rural women about safe delivery, the health educator uses local language terms like "daat wali dhai" (trained midwife) and demonstrates with a cloth doll rather than using medical terms like "aseptic technique" or "episiotomy."

6. Reinforcement

• Definition: Few people can learn everything new in a single session. Repetition at intervals is necessary.
• Without reinforcement, individuals can revert to the pre-awareness stage.
• If the message is repeated in different ways, people are more likely to remember it.
• Example (PSM): The anti-tobacco message "Tobacco kills" is reinforced through multiple channels - pictorial warnings on cigarette packets, radio jingles, school health programs, and IEC (Information, Education, Communication) campaigns - so that the public does not forget the harm of smoking.

7. Learning by Doing

• Definition: Learning is an action-process, not mere memorization.
• The Chinese proverb illustrates this perfectly: "If I hear, I forget; if I see, I remember; if I do, I know."
• Practical, hands-on experience reinforces health concepts far better than passive listening.
• Example (PSM): During a family planning camp, rather than just explaining how to use a condom, the health worker demonstrates it on a model and then asks the participants to practice - this "learning by doing" ensures correct technique is learned and retained.

8. Known to Unknown

• Definition: Teaching should proceed from the concrete to the abstract, from the simple to the complex, from the easy to the difficult, from the known to the unknown.
• Start where the people are and with what they already understand, then proceed to new knowledge.
• Existing knowledge serves as "pegs on which to hang new knowledge."
• Example (PSM): When educating tribal communities about tuberculosis (TB), the health educator begins with what they already know - a prolonged cough ("khasi") leads to weakness. From this known fact, the educator then introduces the new concept of the TB germ (Mycobacterium tuberculosis), the need for sputum testing, and the importance of completing DOTS (Directly Observed Treatment Short-course).

9. Setting an Example

• Definition: The health educator must practise what they preach - lead by personal example.
• An educator explaining the hazards of smoking will not be credible if he smokes himself.
• An educator promoting the "small family norm" loses credibility if his own family is large.
• Example (PSM): A PHC Medical Officer conducting sessions on alcohol de-addiction in the community must himself abstain from alcohol. A nurse educating patients about hand hygiene must be visibly washing her hands before every patient contact.

10. Good Human Relations

• Definition: Sharing of information, ideas, and feelings happens most easily between people who have a good relationship.
• Building good relationships goes hand in hand with developing communication skills.
• Health education is fundamentally a human interaction - not a one-way broadcast.
• Example (PSM): An ASHA worker who regularly visits homes, knows families by name, attends local events, and speaks the local dialect builds a trusting relationship with her community. This rapport makes her messages about antenatal care, nutrition, and immunization far more accepted than those from an outsider.

11. Feedback

• Definition: Feedback is a key concept of the systems approach - it allows the health educator to modify elements (message, channels, approach) based on audience response.
• For effective communication, feedback is of paramount importance.
• It can be verbal (questions asked, responses given) or non-verbal (body language, attendance, behaviour change).
• Example (PSM): During an IEC session on family planning in a PHC, the health worker observes that women are not asking questions and look confused. Taking this feedback, she switches from pamphlets to flip charts with pictures and uses simpler local language in subsequent sessions - improving understanding and uptake of contraception.

12. Leaders (Opinion Leaders / Key Communicators)

• Definition: We learn best from people whom we respect and regard (psychologists' established principle).
• Health education should work through local leaders - village headman, school teacher, political worker, religious leader.
• Leaders are agents of change; if convinced first, implementing the programme becomes easier.
• Attributes of a good health education leader: understands community needs, provides guidance, takes initiative, is receptive to people's views, identifies with the community, and is selfless and honest.
• Example (PSM): During a polio eradication campaign in an area with vaccine hesitancy (e.g., some Muslim communities refusing OPV due to rumours), the health authorities first engaged local Islamic religious leaders (Imams) and convinced them about vaccine safety. Once these respected leaders endorsed the campaign from the mosque pulpit, community acceptance increased dramatically.
