The transtheoretical model is a way of thinking about behavior change. It explains that people go through different steps as they work to change their behavior. For example, if a child wants to learn to ride a bike they may start by first deciding they want to do it (the first step), then actually getting on the bike and trying it out (the second step), and then they practice and learn the skill (the third step). The transtheoretical model helps us understand what steps a person needs to take to reach their goal and provides tips on how to help them get there.
