The theory of reasoned action serves to understand an individual's voluntary behavior.[2] The ideas found within the theory of reasoned action have to do with an individual's basic motivation to perform an action. According to the theory, intention to perform a certain behavior precedes the actual behavior.[3] This intention is known as behavioral intention, and comes as a result of a belief that performing the behavior will lead to a specific outcome. Behavioral intention is important to the theory because these intentions "are determined by attitudes to behaviors and subjective norms".[4] The theory of reasoned action suggests that stronger intentions lead to increased effort to perform the behavior, which also increases the likelihood for the behavior to be performed.
