Diffusion Theory

Five steps in the process of acquiring new ideas:

1. Awareness. The person discovers the idea.

bulletMass media coverage is most helpful at the stage of creating awareness.
bulletNews coverage, editorials and advocacy help build awareness.
bulletPublic service messages (broadcast) and advertising introduce the ideas.

2. Interest. The person seeks more information.

bulletControlled direct media: face-to-face, direct mail, brochures, newsletters.
bulletEvents: seminars, meetings, open houses (and similar), exhibits.

3. Trial. The person tries the idea on others and/or tests the behavior change.

bulletMay be shaped by p.r. through volunteer experience and other positive reinforcement.
bulletPersonal contacts of various kinds are most useful at this stage.

4. Evaluation. The person decides whether the idea is in his or her own self-interest.

bulletControlled media and personal experience have some impact on how the individual evaluates the experience or idea.
bulletNow is the time to show strong appreciation, reinforce positive aspects of the opinion or action, and reassure the individual that the choice was a good one — again, personal one-on-one contact whenever possible.
bulletControlled media can also be useful at this point.

5. Adoption. The person incorporates the idea into his or her opinion/behavior.

bulletAt this point, p.r. can continue to reinforce and strengthen the sense of "rightness" surrounding the decision.
bulletControlled media can play a strong role in maintaining the newly adopted opinion and/or behavior.
