The six stages of change are precontemplation, contemplation, preparation, action, maintenance, and termination. This framework, known as the Transtheoretical Model, was developed by psychologists James Prochaska and Carlo DiClemente in 1982 and originally applied to smoking cessation. It has since been used across dozens of behavior changes, from diet and exercise to managing chronic conditions.
The core idea is simple: people don’t go from zero to changed overnight. They move through a predictable sequence of mindsets, and understanding where you are in that sequence can help you figure out what kind of support or strategy actually works for you right now.
Stage 1: Precontemplation
In precontemplation, a person has no intention of changing within the next six months. They either don’t see their behavior as a problem or they’re unaware of its consequences. Someone in this stage might say, “I don’t see a problem with what I’m doing, so there’s no reason to change anything.” This isn’t stubbornness in the traditional sense. It’s often a genuine blind spot, sometimes reinforced by denial or by a lack of information about the risks involved.
If you recognize yourself here, the most useful thing isn’t a plan of action. It’s simply learning more. Reading about the consequences of a behavior, listening to other people’s experiences, or reflecting on how the behavior affects the people around you can slowly shift awareness without pressure to act.
Stage 2: Contemplation
Contemplation is marked by awareness. You know there’s a problem, and you’re seriously thinking about doing something about it. The internal monologue sounds more like, “I know I have a problem, and I think I should do something about it.” But there’s still real uncertainty. You’re weighing the effort and discomfort of changing against the benefits, and you haven’t tipped decisively toward action.
People can stay in contemplation for a long time. The model doesn’t put a strict deadline on it, but the hallmark is that you’re genuinely open to information. You might be reading articles (like this one), talking to friends who’ve made similar changes, or quietly researching options. The risk at this stage is chronic ambivalence, where you keep weighing pros and cons without ever committing. Writing out a concrete list of what you gain and lose from changing can help make the decision feel less abstract.
Stage 3: Preparation
In the preparation stage, the internal debate is over. You’ve decided the benefits of changing outweigh the costs, and you intend to take action within the next 30 days. Most people in this stage have already taken small behavioral steps in the past year, like buying running shoes, scheduling an appointment, or telling someone about their plans.
This is the planning stage. You’re gathering information from books, counselors, or programs and putting together a specific plan. The key word is specific: not “I’ll eat healthier,” but “I’ll meal prep on Sundays and replace my afternoon snack with fruit.” The more concrete the plan, the smoother the transition into the next stage. Setting a start date, identifying your biggest obstacles, and building a support system all happen here.
Stage 4: Action
Action is where the visible change happens. You’ve modified your behavior, your environment, or both. In the original model, this stage covers roughly the first six months of the new behavior. It’s the most demanding stage because it requires the most time, energy, and willpower. Confidence builds during this period as you start to see evidence that you can actually sustain the change.
The first days and weeks of action are when relapse risk is highest. Strategies that help include restructuring your environment (removing triggers, adding reminders), rewarding yourself for hitting milestones, and leaning on your support network. If you slip, the model treats that as a normal part of the process rather than a failure. Most people cycle through the stages more than once before the change sticks, moving in a spiral pattern rather than a straight line.
Stage 5: Maintenance
You enter maintenance once you’ve sustained the new behavior for more than six months. The focus shifts from making the change to protecting it. Temptation decreases over time, and your confidence in maintaining the new behavior grows. But this stage still requires active effort: staying aware of situations that could trigger a relapse, reinforcing the habits that support the change, and remembering why you started.
Maintenance can last years. For some behaviors, it’s essentially a lifelong stage. The difference between maintenance and action is largely psychological. In action, you’re proving to yourself that change is possible. In maintenance, you’re integrating the change into your identity. You stop thinking of yourself as someone who is quitting smoking and start thinking of yourself as a nonsmoker.
Stage 6: Termination
Termination is the final stage, and it’s the most controversial. It describes a point where you have zero temptation to return to the old behavior and complete confidence in your ability to maintain the change, regardless of the situation. You no longer need to actively work at it because the old behavior simply holds no appeal.
This stage is not always included in discussions of the model because it’s extremely difficult to achieve. For many behaviors, especially addictions, most people remain in long-term maintenance rather than reaching true termination. That’s not a failure. It’s a realistic acknowledgment that some behaviors require ongoing vigilance even after years of success.
Why the Stages Aren’t a Straight Line
One of the most important features of this model is that it doesn’t treat progress as linear. People commonly move forward a stage or two, experience a setback, and cycle back to an earlier stage before progressing again. A person who has been in the action stage for three months might relapse and return to contemplation, then move through preparation and action again with new knowledge about what triggered the slip.
This spiral pattern is built into the model’s design. Each time you cycle through the stages, you typically learn something that makes the next attempt more informed and more durable. Research across a range of behaviors, from diet and physical activity to blood sugar management and blood pressure control, has found that people who advance through the stages show measurable improvements in self-confidence, perceived benefits of the new behavior, and actual health outcomes.
How to Identify Your Current Stage
Figuring out where you are is straightforward if you ask yourself a few honest questions. Are you even thinking about changing? If not, you’re in precontemplation. Are you thinking about it but haven’t committed? That’s contemplation. Have you set a date and started planning? Preparation. Are you actively doing the new behavior but it still takes effort? Action. Have you been at it for more than six months? Maintenance.
The practical value of identifying your stage is that it tells you what kind of help is actually useful right now. Giving a precontemplator a detailed exercise plan is premature. They need awareness, not logistics. Giving a contemplator another list of reasons to change might just fuel more analysis paralysis. They need help making a decision. And giving someone in action a lecture about why change matters is completely beside the point. They need strategies for handling triggers and building momentum. Matching your strategy to your stage is what makes this model more useful than a generic list of tips.
Limitations Worth Knowing
The stages of change model is widely used in health coaching, therapy, and public health programs, but it has real limitations. Some researchers have questioned whether the stages are truly distinct categories or whether readiness to change is more of a continuous spectrum. Studies on physical activity in older adults have found that people already in the action or maintenance stages at the start of an intervention don’t benefit much from stage-matched approaches, which makes sense but limits the model’s usefulness in some populations.
There’s also debate about whether interventions based on the model are genuinely “theory-driven” or simply inspired by the general concept of stages. Some studies using all components of the model have still shown no significant improvement, raising questions about how well the theory translates into specific, repeatable interventions. The model is best understood as a useful lens for thinking about where you are in a change process, not a precise clinical tool with guaranteed outcomes.
