Health Belief Model
Predictive model used to predict what a person is going to do
Perceptions guide behavior
Perceptions are usually inaccurate
![Page 3: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/3.jpg)
Health Belief Model
Individuals are more likely to take preventive actions to asymptomatic conditions if:
1. They perceive that they are personally susceptible to the disease or condition.
![Page 4: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/4.jpg)
Health Belief Model
Individuals are more likely to take preventive actions to asymptomatic conditions if:
2. They perceive that occurrence of the
disease/condition would severely affect
at least some component of their life.
![Page 5: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/5.jpg)
Perceived Seriousness
Trigger factors such as alarming symptoms, advice from family or friends, messages from the media, disruption of work or play.
![Page 6: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/6.jpg)
Health Belief Model
Individuals are more likely to take preventive actions to asymptomatic conditions if:
3. They perceive that taking a certain preventive action would be beneficialin either reducing the susceptibility orseverity if the disease/condition didoccur.
![Page 7: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/7.jpg)
Health Belief Model
Individuals are more likely to take preventive actions to asymptomatic conditions if:
4. They perceive that taking a given
action would not entail overcoming
important barriers (Eg. cost, fear,
embarrassment, pain, inconvenience)
![Page 8: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/8.jpg)
HBM ConclusionsThe model is most effective when used to predict preventive health behaviors such as obtaining vaccinations to avoid specific illnesses.
It is less effective when the preventive action is not associated with a specific threat (Eg. Annual physical exams)
The benefits/barriers component of the model seems to have more predictive value than any other single component.
![Page 9: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/9.jpg)
HBM Conclusions
The model is effective when the preventive behavior is a short term or “one shot” action
It is less effective when the preventive behavior requires a long term, established routine (Eg. Hypertension medication)
Relatively little research has examined the “cues to action” component of the model

Theory of Reasoned Action
Knowledge, attitudes, and behavior
Attitudes do effect behavior but not as simple as one might think
Developed by Fishbein (1967)
Concerned with relations between beliefs, attitudes, intentions, and behaviors
Distinguishes between attitude toward an object and attitude toward a behavior
Attitude toward breast cancer vs. Attitude toward mammography
![Page 15: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/15.jpg)
Behavioral Intention
Perceived likelihood of performing the behavior
Must be a “firm” indication of intent
Affecting “intent” is the goal of a TRA based intervention
![Page 16: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/16.jpg)
Attitude Towards BehaviorBehavioral Belief
Belief that behavioral performance is associated with certain attributes or outcomes
Influential factors?
Past experience
Information received or not received
Social influences (family, peers, etc.)
Evaluation
Value attached to a behavioral outcome or attribute
![Page 17: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/17.jpg)
Subjective Norm
Normative BeliefBelief about whether each referent approves or disapproves of the behavior (Supportive Env.)
Most influential referents? (Media, teachers, peers, parents, spouses, etc.)
Motivation to ComplyMotivation to do what each referent thinks
Parents vs. Peers?
![Page 18: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/18.jpg)
Theory of Planned Behavior
Adds one component to the TRA…Perceived Behavioral Control
To account for factors outside the individual’s control that may affect intention and behavior
Based on the idea that behavioral performance is determined jointly by motivation (intention) and ability (behavioral control) (skills and resources)
![Page 19: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/19.jpg)
Theory of Planned Behavior
Perceived Behavioral Control A person’s perception of the ease or difficulty of behavioral performance
Similar to self efficacy (Inc. w/ repeated successes
What characteristics is the person with a high perceived behavioral control likely to have?

Applying Stages of Change
Program Planning/Needs Assessment
Use in needs assessment surveysBehavior is not dichotomous
Use stages to form questions
Determine the current stage of readiness of population

Measuring the Stages

___ Never smoked, or quit for at least 5 years (skip Quest).
____ Yes, I have for more than 6 months.____ Yes, I have, but for less than 6 months.____ No, but I intend to in the next 30 days and have
tried for at least 24 hours in the past year.____ No, but I intend to in the next 6 months.____ No, and I do not intend to in the next 6 months.

Positive Psychology
Martin SeligmanAPA President 1996Psychology split into two camps:Academics more interested in science.Clinicians interested in practice of psychotherapy.Hoped to bring science and practice together.
![Page 34: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/34.jpg)
Nikki and the weeds
Seligman’s inspiration.
Weeding garden.
5-year old daughter throwing weeds.
Seligman irritated, yelled at Nikki.
“Daddy. From when I was 3 until I was 5, I was a whiner. I whined every day. On my 5th birthday, I decided I wasn’t going to whine anymore. That was the hardest thing I’ve ever done. If I can stop whining, you can stop being such a grouch.”
![Page 35: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/35.jpg)
An epiphany
Seligman resolved to change.
His purpose in life was not to correct his daughter’s shortcomings.
Instead, raising her to nurture the strength she displayed (social intelligence).
Can psychological science be about identifying and nurturing strengths?
His mission as APA president.
![Page 36: Health Psychology Chapter 6: Staying Healthy Oct 3-5, 2007 Classes #18-19.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649efc5503460f94c0f989/html5/thumbnails/36.jpg)
Seligman (1998)
He calls this new orientation “Positive Psychology”…
At the subjective level, the field is about positive experience: well being, optimism, etc.At the individual level it is about the character strengths—Love, vocation, courage, aesthetic sensibility, leadership, perseverance, forgiveness, originality, future-mindedness, and geniusAt the community level it is about the civic virtues and the institutions that move individuals toward better citizenship: responsibility, parenting, altruism, civility, moderation, tolerance, and work ethic

Seligman (1998)
We’ll have to wait and see if psychology moves in this direction…
