The Theory of Reasoned Action/Theory of Planned Behavior (TRA/TPB) is one of the classics of behavioral theory… but what does it offer that some of the other “classics” we’ve explored — like Social Cognitive Theory and the Health Belief Model — do not? In this episode, we look at the constructs of the TPB, some of its pros and cons, and discuss when you might want to consider it.
