Perceived Behavioral Control

Perceived behavioral control refers to people's perceptions of their ability to perform a given behavior. Drawing an analogy to the expectancy–value model of attitude (see attitude toward the behavior), it is assumed that perceived behavioral control is determined by the total set of accessible control beliefs, i.e., beliefs about the presence of factors that may facilitate or impede performance of the behavior. Specifically, the strength of each control belief (c) is weighted by the perceived power (p) of the control factor, and the products are aggregated, as shown in the following equation. 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.
