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:

    I take it that what all men are really after is some form or perhaps only some formula of peace.
    Joseph Conrad (1857–1924)

    Every formula which expresses a law of nature is a hymn of praise to God.
    Maria Mitchell (1818–1889)

    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)
