theries of health behavior Flashcards
What is theory from a health and disease prevention perspective?
Theory explains behavior and suggests ways to achieve behavior change. It represents an interrelated concepts, definitions, and propositions that serve to explain health behavior or provide a systematic method of guiding health promotion practice
What is a model
A composite or mixture of ideas or concepts taken from any number of theories and used together - they help us understand a specific problem in a particular setting that one theory alone can’t do
Intrapersonal Theories
factors within the person that influence behavior such as knowledge, attitudes, beliefs, motivation, self-concept, developmental history, past experience, adn skills. Some theories and models include the Health Belief Model, the Theory of Reasoned Action, Self-Efficacy Theory, Attribution Theory and the Transtheoretical model.
Interpersonal Theories
Other people influence our behavior by sharing their thoughts, advice and feelings and by emotional suport and assistance (social network, healthcare providers, etc). Social Cognitive theory is a common one.
Community-level Theories
Factors within social systems (communities, organizations, institutions, and public policies) such as rules, regulations, legislation, etc. Diffusion of Innovation, social Ecoloical Model and Social Capital Theory are all examples of this level of theory.
Why do we have theories in relation to health behavior?
We need to solve a problem or explain behavior.
Inductive reasoning
starts with specific observations or evidence and moves to a conclusion - using inductive reasoning we observe that HIV is transmitted through sexual activity and we observe that condoms preven the transmission of disease through sexual activity, therefore we conclue that condoms prevent the transmission of HIV
Deductive reasoning
Starts with the conclusion - condoms prevent the transmission of HIV, and seek the observations to support the conclusion.
Health Belief Model
Developed by researchers at US Publi Health Service in 1950s as a means to understand why so few people were being screened for TB. https://www.youtube.com/watch?v=A9YYWY5qPbo
What is a health behavior?
All of those things we do that influence our physical mental emotional psychological and spiritual selves. Many factors influence health behaviors such as SES, skills, etc.
How does socioeconomic status influence health behaviors?
SES makes a significant contribution to health since it encompasses education, income and occupation. People wiht more education tend to live in safer homes, have better health insurance, and access to healthier foods.
How do skills influence health behavior?
Behavior is influenced by having both knowledge and skills - as an example, people may know that condoms decrease HIV transmission but if they don’t know how to use condoms . . .
How does culture influence health behavior
Sometimes people with knowledge and skills still dno’t use what they know - often because of cultural norms. Would you stop showering daily if it turned out it was better for skin?
How do beliefs contribute to health behaviors?
Beliefs are woven within culture they are one’s own perception of what is true, such as going outside with a wet head causes pneumonia
How does attitude affect health behaviors?
When there are a series of beliefs, you get attitudes - the concept that multiple beliefs contrbute to a thought or concept - wet hair, wet socks, and being cld causes pneumonia.
How do values contribute to health behaviors?
What is important to people - what we value influences the types of behaviors we adopt - if someone values health they may be more likely to work out, etc.
How does religion contribute to health behaviors?
Fasting, dietary restrictions, circumcision, etc.
How does gender contribute to health behaviors?
Men engage in fewer health-promoting behaviors and have less healthy lifestyles than women.
Constructs
The way concepts are used in a specific theory. Each theory has a concept at heart, and a series of constructs that indicate how a concept is used in that theory. If a theory is a house, the concepts are the bricks and hte constructs are hte way the bricks are used in the house.
Variable
an operationalized concept - or how the concept is going to be measured - if you are talking in terms of a house, bricks can be measured by square footage, number, size, or weight.
Self efficacy theory
People will only try to do what they think they can do and won’t try to do what they think they can’t do. Constructs
Mastery experience: Prior success at having accomplished something that is similar to the new behavior
Vicarious experience: learning by watching someone similar to ourselves
Verbal persuasion: encouragement by others
Somatic and emotional states: the physical and emotional states caused by thinking about undertaking the new behavior.
Proposed by Albert Bandura in late 1970s - Bandura, 1977, 2004
Early Theories felt that . . . .
- behavior is regulated physically at a subconscious level; behaviors diverging from the prevailing norm are a symptom of a disease or disorder; behavior changes as a result of gaining self-insight throughanalysis with a therapist
Mastery experience
a construcf of self efficacy theory - the concept that if you have experience at something, you’ll be better at it later - as an example babysitting and confidence as a new parent
Vicarious experience
A construct of self efficacy theory - the observation of successes or failures of others who are similar to yourself . . .
Verbal persuasion
A construct of self-efficacy theory - when people are verbally persuaded that they can master a task, it boosts their self-efficacy and makes them more likely to do a task
Somatic and emotional states
A construct of self-efficacy theory - the physical and emotional states that occur when someone contemplates donig somethin gprovide clues as to the likelihood of success or failure. Stress, anxiety, worry, and fear all negatively affect self-efficayc and can lead to a self-fulfilling prophecy of failure.
Self Efficacy has 2 key concepts
- self-efficacy expectations and outcome expectations.
Theory of reasoned action/planned behavior
Health behavior is influenced by intention. Constructs:
Attitude: a series of beliefs about something that affects the way we think and behave
Subjective norms: the behaviors we perceive important people expect of us and our desire to comply with those expectations
Volitional control: the extent to hwich we can decide to do something, at will
Behavioral control: the extent of ease or difficulty we believe hte performance of a behavoir to be
Theory of Reasoned Action proposed first - useful in explaining behaviors under someone’s willful (volitional) control, but not inother behaviors.
Theory of Planned Behavior proposed as an addendum - intention is influenced by attitudes, subjective norms and behavoiral control
Attitudes
A construcf of TRA/TBP - formed by a series of beliefs and result in a value being placed on a behavior. If someone believes eating soy is healtheri than eating animal protein, better for the enviroment, etc, their attitude toward eating soy is better.
Subjective norms
A construct of TRA/TBP - the perceived social pressure to engage or not engage in a certain behavior - it is determined by normative beliefs. Tese are behaviors we perceive important people in our lives expect from us.
Volitional Control
A construct of TRA/TBP - behavior is the result of a person’s intention to do something - the behavior has to be under volitional control for this to happen. Eating breakfast, the type of exercise, etc. is all under volitional control. Making a sports team is an example of something not under volitional control.
Behavioral control
A construct of TRA/TBP - in situations where there is less volitional control, even when intention si great, the TRA is not useful in predictive or explaining behavior. To address this, behavioral control was added to the theory. Behavioral control is the perceived control over performance of a behavior. For the lacrosse player who didn’t make the team, behavioral control influenced his intention to try out - he believed it would make it easy for him to make hte team.
Theories are used as the basis for behavior change interventions because they identify:
why people do what they do.
Repeated observation of higher rates of injury among teen athletes during practices with minimal attention to safety equipment use and lower rates during games with maximum attention to safety equipment use leads to the conclusion that safety equipment prevents injury is an example of:
Inductive reasoning
Theories
come from a need to solve a problem.
Models differ from theories in that they
are based on concepts from different theories rather than just one.
Theories at the ___________level focus on the assumption that other people in our lives affect our health decisions and thus, our health behavior.
. Interpersonal
Theories are used as the basis for public health programs or interventions because they provide:
a possible explanation for health behavior.
Lowering sodium intake reduces stroke risk. Stroke risk is highest among people with high blood pressure. Lower sodium diets help control high blood pressure. This is an example of:
Deductive reasoning
Changing the legal limit for a DUI arrest would be consistent with which theoretical level of intervention
Community
When using community level theories, behavior change is predicated on
changing factors within social systems.
The foundation of self efficacy Theory
At times, your role as a health educator will be to empower your target population to believe in themselves. When this is needed, the Self-Efficacy Theory should be the basis used for the intervention. The keyword to remember with this theory is believe.
When you need to change the intention of an individual or society
Sometimes, people will make a decision to engage in a particular behavior. For example, teenagers may decide to drink alcohol underage. The reasons may be varied and can include rebellion and peer pressure, Whatever the reason, the teens are intending to drink alcohol. When trying to change intention in your target population, then the Theory of Planned Behavior should be used as the foundation of the intervention. The keyword to remember with TPB is intention.
According to the construct of volitional control, if engaging in a behavior is perceived as being easy, then the likelihood of engaging in the behavior is greater.
FALSE
According to the Theory of Reasoned Action, behavior is affected by volitional control because it:
affects intention to engage in a behavior.
Which of the following demonstrates use of the Self Efficacy Theory construct of vicarious experiences to increase physical activity among older adults?
The county health department offers hikes led by a retired physical education teacher.
Of the following, which is consistent with behavior change for heart disease risk reduction based on increasing self-efficacy through mastery experiences?
Teaching people how to make heart healthy food choices and having them revamp their meals.
The Theory of Reasoned Action explains behavior based on:
Intrapersonal factors
Which of the following best summarizes the concept of the Self-Efficacy Theory?
People will only attempt to do what they think they can do
Which construct of Self-Efficacy Theory would you use to explain behavior based on the support we get from others.
Verbal persuasion
The difference between the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB) is that the TPB:
subjective norms
If you were using the Theory of Reasoned Action/Planned Behavior, to change behavior, which of the following would be your focus?
altering intention.
Which construct of the Self-Efficacy Theory would you use to explain behavior based on past success engaging in a similar behavior?
Mastery experiences
Volitional control refers to:
behavior we can engage in, at will
According to the Theory of Reasoned Action/Planned Behavior, a person’s attitude toward a behavior results from:
beliefs about the behavior
When a woman says she avoids going for a mammogram because the very thought of even being screened for breast cancer frightens her, which of the Self-efficacy theory constructs would explain this behavior?
Somatic and emotional states
Which of the following best exemplifies people with high levels of self-efficacy?
They approach a difficult task as a challenge to be overcome, rather than avoided.
Self-efficacy is increased through vicarious learning if:
the person being observed is like the observer.
Health Belief Model
Personal beliefs influence health behavior: health behavior is determined by personal beliefs or perceptions about a disease and the strategies available to decrease its occurrence. https://www.youtube.com/watch?v=A9YYWY5qPbo
Perceived susceptibility
A construct in the health belief model: an individual’s assessment of his or her chances of getting a disease
Perceived benefits
Construct in health belief model: An individual’s conclusion as to whether the new behavior is better than what he or she is already doing
Perceived barriers
A construct in health belief model: An individual’s opinion as to what will stop him/her from adopting a new behavior
