Challenges to Wellness: Access to Challenges to Wellness: Access to Health InsuranceHealth InsuranceNearly 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.

Self-EfficacySelf-EfficacyRefers 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 TheoryDeveloped 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 PrinciplesFive Principlesof Social Cognitive Theoryof Social Cognitive Theory1. People learn from watching others.2. Learning is an internal process that may or
may not change behavior.3. Behaviors are targeted toward specific
goals.4. Behavior eventually becomes self-regulated.5. Reinforcement and punishment have both
direct and indirect effects.
Health Belief ModelHealth Belief ModelPeople will engage in a health-related action if
1. 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 ControlLocus of ControlLocus 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 behaviorLack confidence to obtain or overcome health
habitsInternal control:
Belief that personal decisions affect actionsMore confident in your ability to change a
behavior
