2. Introduction
I t d ti
• Primary prevention of diseases is a challenging task
– Often, adopting healthy lifestyles require people to change their
familiar habits and give up their preferred ways of living
familiar habits and give up their preferred ways of living
– These changes are not easy, since they often require extra time,
strong willpower and considerable mental effort
– The changes often affect parts of our lives not completely within
The changes often affect parts of our lives not completely within
our control (e.g. work, family, economic situation)
Why should I make these ”sacrifices” to prevent diseases
that are uncertain to occur even in the distant future
that are uncertain to occur even in the distant future ‐
especially, when I feel completely healthy?

8. Environmental contexts
E i t l t t
• Physical and social environments:
Public policy
the context for behavior
– Available options
– Ways to present the choices Community
• The choice architecture of the Organizational
decision context
– supports or discourages a
pp g
behavior Interpersonal
– guides the formation of habits
– Is built by actors from multiple
levels Individual

10. Main implications for interventions
M i i li ti f i t ti
• Primary aims:
– Create or strengthen intention
– Increase abilities and remove barriers
Increase abilities and remove barriers
– Modify environmental contexts
• E i
Environmental contexts have a significant influence on

behavior
Make changes on multiple levels through involving different actors
Make changes on multiple levels through involving different actors
Guide people with appropriate choice architectures
Offer immediate, tangible benefits for healthy behaviors
• Take advantage of trigger events in people’s lives

11. Technology‐aided persuasion
T h l id d i
• Persuasive technology can
change attitudes and behavior
• Three roles:
– Tool
– Medium
– Social actor
• Persuasive design: provide

13. A tentative plan for a personal profile

Variables to be included
• current health behavior together with risk Ability

• degree of intention towards healthy Reasoned

• motivators or incentives
motivators or incentives
• resources Barriers
• variables that quantify the health
behavior, intention, motivators and

resources
• channels through which the individual can

be best reached
• dynamicity: significant life course events
that modify the profile variables

16. Targeting or tailoring?
T ti t il i ?
• Targeting: defining a subgroup of a population based on
common characteristics for which an appropriate
intervention is created
intervention is created
• Tailoring: fitting an intervention to meet the personal
needs and characteristics of a person rather than a group
needs and characteristics of a person rather than a group
• Do‐It‐Yourself: provide a platform and let the person
personalize the interventions/services by himself
Can effective interventions be designed based on
ff g
segmentation (targeting), or are the individual needs
associated with health behavior change too complex for
this approach?

17. Questions
Q ti
• Are there important theories missing?
h i h i i i ?
• Are some important behavioral determinants missing?
• Comments to the segmentation approach?
• Can effective interventions be designed based on segmentation (targeting),
Can effective interventions be designed based on segmentation (targeting)
or are the individual needs associated with health behavior change too
complex for this approach?
– Segmentation vs. individualization (targeting vs. tailoring) – which is the way to
go?
?
– What level of detail is required in segmentation to achieve practical usefulness –
the “accuracy level” of each dimension, what are the values for the dimensions?
– How to apply tailoring? (limited resources)
– What if we provide intervention platform that the person could personalize
h f d l f h h ld l
himself?
• Can the dynamicity of the profile be captured by the profiling variables?
– How to include personal life events?
• How can we quantify intentions, motivators, resources and channels of
individuals?
• If you were to develop a program related to primary prevention of diseases,
what information you would need of your target audience?
