when was the theory of planned behavior developed?
1840s
the theory of planned behavior was proposed by icek ajzen in 1985 through his article "from intentions to actions: a theory of planned behavior." the theory was developed from the theory of reasoned action, which was proposed by martin fishbein together with icek ajzen in 1980. the theory of reasoned action was in turn grounded in various theories of attitude such as learning theories, expectancy-value theories, consistency theories (such as heider's balance theory, osgood and tannenbaum's congruity theory, and festinger's dissonance theory) and attribution theory. according to the theory of reasoned action, if people evaluate the suggested behavior as positive (attitude), and if they think their significant others want them to perform the behavior (subjective norm), this results in a higher intention (motivations) and they are more likely to do so. a high correlation of attitudes and subjective norms to behavioral intention, and subsequently to behavior, has been confirmed in many studies.
theory of planned behavior
to the extent that it is an accurate reflection of actual behavioral control, perceived behavioral control can, together with intention, be used to predict behavior.

the theory of planned behavior can cover people's non-volitional behavior which cannot be explained by the theory of reasoned action.









































an individual's behavioral intention cannot be the exclusive determinant of behavior where an individual's control over the behavior is incomplete. by adding "perceived behavioral control," the theory of planned behavior can explain the relationship between behavioral intention and actual behavior.
