an indication of an individual’s readiness to perform a given behavior. It is assumed to be an immediate antecedent of behavior. It is based on attitude toward the behavior, subjective norm, and perceived behavioral control, with each predictor weighted for its importance in relation to the behavior and population of interest

behavior
answer

an individual’s observable response in a given situation with respect to a given target.

Strengths of the theory
answer

-can cover people’s non-volitional behavior which cannot be explained by TRA -an individual’s behavioral intention cannot be the exclusive determinant of behavior is incomplete. By adding PBC, the TPB can explain the relationship between behavioral intention and actual behavior -includes social norm as a factor
question

Limitations of the theory
answer

-some scholars claim that the theory of planned behavior is based on cognitive processing and have criticized the theory on those grounds.
question

Applications of TPB
answer

-health studies: improve predictability of intention in various health-related fields such as condom use, leisure, exercise, and diet. -pro-social behaviors such as charitable giving -environmental psychology: generally, actions that are environmentally friendly carry a positive normative belief. (sustainable behaviors are widely promoted as positive behaviors) BUT even though there may be a behavioral intention to practice these behaviors, perceived BEHAVIORAL CONTROL can be hindered by constraints such as belief that one’s behavior will not have any impact.
