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)

    Ideals possess the strange quality that if they were completely realized they would turn into nonsense. One could easily follow a commandment such as “Thou shalt not kill” to the point of dying of starvation; and I might establish the formula that for the proper functioning of the mesh of our ideals, as in the case of a strainer, the holes are just as important as the mesh.
    Robert Musil (1880–1942)

    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.
