Theory of Planned Behavior - Formula

Formula

In its simplest form, the theory of planned behavior can be expressed as the following mathematical function:

BI: Behavioral intention

AB: Attitude toward behavior

(b): the strength of each belief

(e): the evaluation of the outcome or attribute

SN: Subjective norms

(n): the strength of each normative belief

(m): the motivation to comply with the referent

PBC: Perceived Behavioral Control

(c): the strength of each control belief

(p): the perceived power of the control factor

W' : empirically derived weight/coefficient

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.

Famous quotes containing the word formula:

    The formula for achieving a successful relationship is simple: you should treat all disasters as if they were trivialities but never treat a triviality as if it were a disaster.
    Quentin Crisp (b. 1908)

    Given for one instant an intelligence which could comprehend all the forces by which nature is animated and the respective positions of the beings which compose it, if moreover this intelligence were vast enough to submit these data to analysis, it would embrace in the same formula both the movements of the largest bodies in the universe and those of the lightest atom; to it nothing would be uncertain, and the future as the past would be present to its eyes.
    Pierre Simon De Laplace (1749–1827)

    In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.
