⭐⭐⭐⭐⭐
score is between 0 and 5
The Theory of Planned Behavior (TPB) is a psychological theory that aims to predict and understand human behavior by analyzing the underlying intentions behind actions. Developed by Icek Ajzen in 1985, TPB extends the earlier Theory of Reasoned Action by adding perceived behavioral control as a key factor influencing both intentions and behavior. It posits that an individual's behavioral intentions are influenced by their attitudes toward the behavior, subjective norms, and perceived behavioral control, ultimately shaping whether the behavior is enacted.
