Lecture 10 Flashcards
what are the four models of health behavior change?
- health belief model
- theory of planned behavior
- transtheoretical model
- cognitive-behavioral therapy approaches
which model is subjective?
health belief model
in the health belief model, you have to believe two things:
1) there is a health threat (you are susceptible, it is severe)
2) you can reduce that threat (it will work, benefits > barriers)
strengths of the health belief model:
- includes useful constructs
- focuses on people’s beliefs
weaknesses of health belief model:
- assumes behavior is rational
- assumes people have the skills to alter behavior
- ignores social context of many health behaviors
- most relevant for “preventative behaviors”
what are the strengths of theory of planned behavior?
- incorporates social health aspect go health behaviors (norms)
- doesn’t assume people want to be healthy (attitudes)
- includes person’s beliefs about their ability to change (control)
what is the theory of planned behavior?
- you must have the intention to change behavior
(based on positive beliefs about the outcome + positive evaluations of the outcome) - you must have
the support of people who matter to you + motivation to comply with norms - you must feel you are capable of doing it + that the action will have the intended effect
what are the stages of the transtheoretical model?
- precontemplation
- contemplation
- preparation
- action
- maintenance
what’s an example of a goal about outcome?
“I want to lose 5 lb.”
what’s an example of a goal about behavior?
“I want to work out 5x a week” *better because it is measurable!
what is a variable reinforcement schedule?
when you stagger the behaviors needed to get a reward (ex. every three times you go for a run, you can have ice-cream)
what is discriminative stimuli?
new stimuli that will trigger you to do something! (ex. putting shoes by door –> go for run!)
