Integrated Behavioral Model

The Integrated Behavioral Model is a combination of the two theories, the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB). The Theory of Reasoned Action used the behavior beliefs and the evaluation of behavior to determine one’s attitude about the behavior that normative beliefs and one’s motivation to comply. It also determines one’s perception of the subjective norms about the behavior with attitude and subjective norms identifying one’s intention to perform the act. This had the effect of being the most crucial determinant of behavior adoption (Montano and Kasprzyk, 2015). Also, with that are the external variables like demographics, personal traits, attitudes, and other individual norms (Health Behavior and Health Education). The Theory of Planned Behavior adds on but with the addition of control as a determinant of behavior (the idea that one’s ability to control beliefs and perceived power determine their perceived authority of the situation). This, along with perceived control as well as attitude and subjective norms, are the constructs that one performs the behavior, and behavior itself.

The Integrated Behavioral Model has four additional factors that directly affect whether or not behavior can be carried out:

  • Knowledge and skills to perform the behavior
  • Salience of the behavior
  • Environmental constraints
  • Habit[1]
