•Cohen's interpretation of effect size r: Small = r ≤ 0.1, Medium = r = 0.25, Large = r ≥ 0.4
•These figures do not easily convert to percentages without distortion. However, as a ballpark figure, if 60% of people were doing the target
behaviour before the campaign, you can predict that about 65% of people will do the health behaviour after the campaign .

25. PERSUASIVE COMMUNICATION MODEL
Cugelman, B., Thelwall, M., & Dawes, P. (2009). Communication-Based Influence
Components Model. Paper presented at the Persuasive 2009, Claremont.

26. 1. SOURCE
• The thing that an audience member interacts
• A person, organization, group, brand, or technology
• Anything that can have a reputation, can be a source
26

27. CREDIBILITY AND TRUST CAN BE BORROWED.
27

28. 28

29. BORROWING CREDIBILITY

30. Featured by X, Y, Z, ad infinitum.
Low credibility websites can borrow credibility from higher credibility sources.
30

31. WHICH PHOTO CAN INCREASE
TEXT CREDIBILITY?
No photo
NGUYEN, H. & MASTHOFF, J. (2007) Is it me or what I say? Source image and persuasion. Persuasive 07. Springer.

32. CREDIBILITY AND VISUALS
Photo Goodwill Trust
High credibility Higher Higher
No photo Middle Middle
Low credibility Lower Lower
Readers perceptions of text credibility
is influenced by photo credibility
32

33. 2. SOURCE MESSAGE
• The actual message that is expressed by the source
• Presented as the persuasion equation:
Click
+ + + Here =
Audience Audience Message &
Message Likelihood
Motivation Capacity Persuasive Call to Action of Change
Ingredients
(8 spheres of influence)
33

34. 3. MESSAGE EXPRESSION &
INTERPRETATION
•The way a message is expressed by the source, and then
interpreted by the audience.
•How you express something can be more important than
what you express
34

35. 35

36. Place the CTA where
most eyes land

37. 4. MEDIA
•The various media used to express something
•Eg. written words, spoken dialogue, photos, video,
interactive websites, email
•Select the media channels most suited to your target
audience
37

38. 38

39. 5. AUDIENCE
• The person, group, organization, or society you are
trying to engage and influence
39

40. DECISION BALANCE (MOTIVATION)
Value proposition
(-) Demotivaror:
Costs, disincentives,
barriers, effort
(+) Motivator:
Goals, carrots,
benefit, drivers
Behaviour is more likely when
motivators outweigh demotivators
40

41. CAPACITY: ABILITY AND EFFICACY
Ability: What you can or can't do
Self efficacy: What you believe you can or can't do
Either way, your ability or self efficacy dictate
what you will and won't do
41

42. 6. FEEDBACK EXPRESSION &
INTERPRETATION
• How the audience expresses and transmits their
feedback to the source, who interprets it
42

43. MANUAL DATA CAPTURE
• Web forms
• Mobile forms
43

44. 44

45. AUTOMATIC DATA CAPTURE
• Sensors: accelerometer, galvanic skin response
• Digital technology: Behaviour goals, Open rates
• Mobile: GPS, QR Codes
45

46. RESEARCH-BASED FEEDBACK
• Marketing research (formative research)
• Focus groups
• Desk reviews
• Iterative pilot testing
• Product / campaign development frameworks
• Social marketing
• Lean startup
• Agile development
46

47. 7. AUDIENCE FEEDBACK
• The feedback that the audience provides to the source,
that is used as the basis for persuasive messages.
• In other words, any data collected about a user that is
processed and acted upon
• The principles within this sphere provide the foundation
for relationship building and interactive design
