The backbone.
CBT · ACT · Stages of change · COM-B · Behavior design
This is really four traditions working together. Cognitive behavioral approaches start from a simple observation: thoughts, situations, and actions are linked in a loop, and changing one link changes the others. So the course spends real time helping you see your own loop, from the cue, to the thought, to the behavior, to the relief that quietly keeps it running. Acceptance and commitment work adds a second move that matters a great deal here. Instead of trying to make an urge disappear, you learn to make room for it without acting on it, and to choose actions that line up with what you actually care about. The overall shape of the program follows a well-studied model of how people move through change in stages, from barely noticing a pattern to maintaining a new one, which is why the early sections do not push for action before there is recognition and a decision; pushing too early tends to produce defense, not change. Underneath all of it is a plain principle from behavior science: a behavior shifts when you change what makes it possible, what triggers it, and what motivates it, not just one of the three. And where it helps, this is paired with simple behavior design, making the better choice a little easier to reach and the automatic one a little harder, so you are not relying on willpower alone in the moments when willpower is thinnest.
