Ajzen's Theory of Planned Behavior is a prominent psychological framework used to predict and understand human behavior in specific contexts. It posits that behavior is driven not only by intentions but also by attitudes toward the behavior, subjective norms, and perceived behavioral control. This theory helps in designing better behavioral interventions by understanding the factors influencing decision-making processes. It is particularly beneficial in areas such as health psychology, marketing, and environmental behavior.
