3The main objectives of the lecture
- To know, what is a THEORY
- To find out, why we need theories
- To get overview of the
- INTERPERSONAL,
- INTRAPERSONAL
- ORGANIZATIONAL
- COMMUNITY and
- POLITICAL theories.
4Health behavior Why is it that...
- many people brush their teeth every morning
night but wont floss? - college students will repeatedly drink so much
alcohol in a single evening that they will get
sick not remember anything about the evening? - some people exercise aerobicly others do not?
- young people begin to smoke use spit tobacco?
- adults who are fully aware of risks associated
with smoking continue to do so? - people will go to an all-you-can-eat buffet
eat until they are uncomfortably full? - some people throw trash out their car window?
5Theory defined
- A theory is a set of interrelated concepts,
definitions and propositions that present a
systematic view of events or situations by
specifying relations among variables, in order to
explain or predict the event or situation
6Why use theories and models?
- A theory based approach provides direction and
justification for program activities and serves
as the basis for processes that are to be
incorporated into the health promotion program
(Cowdery et al., 1995, p. 248) - Theories can provide answers to program
developers questions regarding why people arent
engaging in a desirable behavior of interest, how
to go about changing their behaviors, and what
factors to look at when evaluating a programs
focus (van Ryn Heaney, 1992, p. 326).
7Why use theories
- Helps to focus on the target behavior and the
environmental context - Helps to answer the WHY? WHAT? and HOW? questions
by program planning
8Why use theories 2
- Helps to understand the nature of the targeted
behavior (explanation theory) - Helps to identify the most suitable targets per
program (change theory)
9Why use theories 3
- Helps you focus on the big picture
- Helps others replicate successful program
10Multiple levels of theories and models
- - Intrapersonal
- - Interpersonal
- - Organizational
- - Community
- - Public Policy
11Intrapersonal factors
- Individual characteristics that influence
behavior, such as knowledge, attitudes, beliefs,
and personality traits
12Interpersonal factors
- Interpersonal processes, and primary groups
including family, friends, peers that provide
social identity, support, and role definition
13Organizational factors
- Rules, regulations, policies, and informal
structures, which may constrain or promote
recommended behaviors.
14Community factors
- Social networks and norms, or standards, which
exist as formal or informal among individuals,
groups and organizations.
15Population factors
- Local, state, federal policies and laws that
regulate or support healthy actions and practices
for disease prevention, early detection, control,
and management
16Intrapersonal theories
- Individual - most basic unit of health promotion
- Individual-level models components of
broader-level theories and approaches - Models
- Health Belief Model
- Theory of reasoned action
17Health belief model
Belief in benefits or effectiveness
Beliefs about barriers
PERCEIVED SUCCEPTIBILITY TO RISK
PERCEIVED MOBIDITY RISK
PROBABILITY OF CHANGED BEHAVIOUR
PERCEIVED THREAT
18Health belief model
- Perceived susceptibility and severity of ill
health - Perceived benefits and barriers to action
- Cues to action
- Self-efficacy

22Interpersonal LevelSocial learning theory
- Interaction of individual factors, social
environment, and experience - Reciprocal dynamic
- Observational learning
- Capability of performing desired behavior
- Perception of self-efficacy
23Social learning theory 2 Albert Bandura, 1986
- Three strategies for increasing self-efficacy
- - Setting small, incremental goals
- - Behavioral contracting specifying goals and
rewards - - Self-monitoring feedback can reinforce
determination to change (keep a diary) - Positive reinforcement encouragement helps

27Community organization models
- Analyze how social systems function
- Mobilize communities, organizations, and
policymakers - Use sound conceptual frameworks
- - Community Mobilization

29Community mobilization
- Encompasses wider social and political contexts
- Community members assess health risks, take
action - Encourages empowerment, building on cultural
strengths and involving disenfranchised groups
30Diffusion of innovations theory E.M. Rogers, 1995
- How new ideas, products, and behaviors become
norms - All levels individual, interpersonal, community,
and organizational - Success determined by nature of innovation,
communication channels, adoption time, social
system
31Diffusion of innovations 2
- Nature of innovation
- Relative advantage over what is being replaced
- Compatible with values of intended users
- Easy to use
- Opportunity to try innovation
- Tangible benefits
32Diffusion of innovations 3
- Communication channels
- Mass media (enhanced by listening groups, call-in
opportunities, and face-to-face approaches) - Peers
- Respected leaders
33Diffusion of innovations 4
- Adoption time
- Awareness Intention Adoption Change
- Gradual
- Movement through groups
- Pioneers
- Early adopters
- Masses
34Diffusion of innovations 4
- Social system
- Identify influential networks to diffuse
innovation health systems, schools, religious
and political groups, social clubs, unions, and
informal associations - Identify opinion leaders, peers, and targeted
media channels to diffuse innovations
