Challenges to Wellness
 Obesity epidemic
 According to the Centers for Disease Control and Prevention
(CDC), in 2004 approximately 34% of U.S. adults over age 20 were
obese (CDC 2008).
 Obesity increases the risks of developing certain chronic diseases
such as hypertension, cardiovascular disease, and diabetes.
 Reemergence of infectious diseases
 Rise of antibiotic-resistant bacteria
 More global travelers, both humans and animals
 Crowded living conditions

Challenges to Wellness: Access to
Health Insurance
 Nearly 46.5 million nonelderly Americans didn’t have
health insurance in 2006.
 Low-income people are at the highest risk of being
uninsured.
 The uninsured are more likely to be hospitalized for
medical conditions that could have been avoided if
proper medical care had been received initially.
 The uninsured don’t receive basic preventive care
such as Pap smears, mammograms, annual physicals,
or blood glucose screenings.
Six Dimensions of Wellness
Developed by Bill Hettler, cofounder and president of
the board of directors of the National Wellness
Institute:
 Physical
 Intellectual
 Emotional
 Social
 Spiritual
 Occupational
Reaching and Maintaining Wellness
 Find your current health status and identify areas you
want to change or improve.
 Behavior change models help understand why it’s hard
to change behavior:
 Transtheoretical model
 Self-efficacy and social cognitive theory
 Health belief model
 Locus of control
 Set realistic goals.
Transtheoretical Model
 Focuses on the decision-making process.
 Stages of change
 Behavior change is not a one-step process.
 Other concepts include processes of change and
decision balance.
Stages of Change
 Precontemplation
 Contemplation
 Preparation
 Action
 Maintenance
Self-Efficacy
 Refers to people’s belief in their ability to succeed in
specific situations.
 People with high self-efficacy believe they can master
difficult tasks and don’t avoid those kinds of
challenges.
 It’s vital to changing or adopting a health behavior
because it helps determine your confidence in your
ability to change.
Social Cognitive Theory
 Developed by psychologist Albert Bandura.
 People behave in a certain way because of interaction
among personal factors, behavior, and the existing
environment.
 Helps explain behavior change.
 Helps explain how people develop and maintain
behavioral patterns.
 Helps in designing interventions.
Five Principles
of Social Cognitive Theory

People learn from watching others.
Learning is an internal process that may or may not
change behavior.
Behaviors are targeted toward specific goals.
Behavior eventually becomes self-regulated.
Reinforcement and punishment have both direct and
indirect effects.
Health Belief Model
People will engage in a health-related action if
they have an interest in health matters (health
motivation),
2. they think they are susceptible to a particular illness
(perceived vulnerability),
3. they think the benefits of the treatment outweigh
the barriers to it (perceived barriers and benefits),
and
4. they think a particular illness could be severe
(perceived seriousness).

Locus of Control
 Locus of control is an important aspect of personality
that depends on your view about the main causes of
events.
 External control:
 Belief that outside circumstances guide behavior
 Lack confidence to obtain or overcome health habits
 Internal control:
 Belief that personal decisions affect actions
 More confident in your ability to change a behavior
How to Set Realistic Goals
 Set small goals to help you achieve your overall goal.
 Write down your goal.
 Make your goals specific and measurable.
 Write down when and where you’ll try to change your
behavior.
 Reward yourself whenever you reach a goal.
 Find social support.
