The Theory of Reasoned Action and Theory of Planned Behavior models human behavior. [1] The models were originally developed in the 1960s-1980s and assume human behavior is under voluntary control. [2] The models include components of attitudes, subjective norms, and perceived behavioral control that influence behavioral intentions and actions. [3] The theories work best for behaviors perceived to be under personal control.
