Health Behavior Models Flashcards
Primary Construct in the Theory of Reasoned Action
Behavioral Intention
Behavioral Intention (Theory of Reasoned Action)
Intention is posited to subsequently lead to the adoption of health-protective behaviors.
Dual focus of the Theory of Reasoned Action
First, it suggests that beliefs about health behaviors will largely shape behavioral intent, and second, it suggests that social influences are an equally important influence on behavioral intent.
Construct of social influences in TRA
The idea that benefits and costs are vital determinants of subsequent behavior is clearly applicable. The social benefits, for example, of smoking cessation are likely to carry a great deal of weight in the context of recently passed ETS (environmental tobacco smoke) laws. However, these social benefits may be sparse in communities where smoking is widely accepted. Social costs are also likely to be a robust determinant of behavior change, as going against the grain of prevailing social norms is never easy and seldom reinforcing.

Limitations of HBM:
Designed to predict one time decisions, not quite as good at predicting chronic decisions but the simplicity of it can help us understand what motivates people and is often still applied to chronic behaviors
Limitations of TRA
Does not consider external factors
TPB is simply the theory of reasoned action but with…
with another construct added- an overall comparison of perceptions related to external factors, as well as objective realities that may facilitate and inhibit the adoption of the health behavior.
Value expectancy (TRA, TPB), stages of change models are a subset of those models because…
They are about being motivated enough and having the resourses we need to make a change. The idea of decisional balance is related to that , a persin is not goung to make a change unless the pros outway the cons but the stages model gives a sequence of stages that any person would move through in order to comit to makin a change, making it, and maintaining it.
Relationship between TRA and TPB:
Value–expectancy theories share the common assumption that people have agency (control) over their health-related behaviors; engage in cognitive evaluation processes to decide what, if anything, to do; and are motivated by the result of these processes
