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 . . .
