The stages of change in addiction describe the psychological process people move through before, during, and after changing an addictive behavior. Known as the Transtheoretical Model, it identifies six distinct phases, from not recognizing a problem exists to sustaining change over time. Understanding which stage someone is in explains why direct confrontation often fails and why readiness, not willpower alone, determines whether an intervention actually works.
The stages of change in addiction are precontemplation, contemplation, preparation, action, maintenance, and relapse, based on the Transtheoretical Model developed by James Prochaska and Carlo DiClemente. Movement between stages is rarely linear: most people cycle through contemplation and relapse multiple times before reaching sustained maintenance. Some clinicians count only five stages, treating relapse as an event rather than a stage, which explains why the model appears differently across different sources.
What Are the Stages of Change in Addiction?
The stages of change in addiction are six sequential phases describing a person’s readiness to change: precontemplation (not yet recognizing a problem), contemplation (weighing pros and cons), preparation (planning specific steps), action (actively changing behavior), maintenance (sustaining the change), and relapse (returning to the old behavior, which restarts the cycle rather than ending it). The model applies to addiction recovery but was originally developed to study how smokers quit on their own.
Where the Model Comes From, and Why “5 Stages” and “6 Stages” Are Both Right
Psychologists James Prochaska and Carlo DiClemente developed the Transtheoretical Model in the late 1970s, studying how smokers quit without formal treatment. They noticed the same pattern showing up regardless of the behavior involved, which is why the model later got applied to alcohol use, drug use, weight loss and gambling as well. Their original research compared people who quit smoking entirely on their own against people who quit through formal treatment programs, and found both groups passed through the same identifiable sequence, just at different speeds and with different levels of outside support. That finding is part of why the model resonates in addiction treatment specifically: it suggests readiness matters more than the presence or absence of professional help, even though professional help still changes the odds of success once someone reaches action.
The disagreement over five stages versus six comes down to how relapse is classified. Some versions of the model treat precontemplation through maintenance as the complete cycle, five stages total, and describe relapse as something that can happen at any point rather than a stage in its own right. Other versions, including several widely used in addiction treatment settings, list relapse explicitly as a sixth stage because it has its own recognizable pattern and its own set of clinical responses.
Neither version is wrong. The five-stage version emphasizes that relapse is not a required part of the process. The six-stage version emphasizes that relapse is common enough, and distinct enough in how it presents, that it deserves its own entry rather than being folded into maintenance. This guide treats it as the sixth stage, since that framing tends to be more useful in practice: naming relapse directly makes it easier to plan for.
Question: Are there 5 stages of change or 6 stages of change in addiction?
Answer: Both versions appear in addiction literature. The five-stage version includes precontemplation, contemplation, preparation, action and maintenance, treating relapse as something that can occur at any point rather than a stage of its own. The six-stage version adds relapse as a distinct sixth stage because it follows a recognizable pattern and calls for its own clinical response, which is why many addiction treatment resources list six stages rather than five.
The Six Stages of Change, One by One
Each stage below reflects a different relationship to the idea of change, not a different level of severity. Someone in precontemplation is not necessarily using more than someone in preparation; they are simply not yet convinced there is a problem worth solving. Recognizing the marker signs of each stage matters because the right kind of support looks different depending on where someone actually is, not where you wish they were.
Precontemplation
Precontemplation is the stage where a person does not yet see their substance use as a problem, even when the consequences are visible to everyone around them. This is not usually stubbornness. It often reflects a genuine gap between how the person experiences their own behavior and how others experience it from the outside.
Common markers of precontemplation include minimizing the frequency or amount of use, deflecting when the topic comes up, and pointing to other people’s worse behavior as a comparison point. Confrontation tends to backfire here, since it gives the person something to argue against rather than something to consider. Providing specific, non-judgmental information about consequences, without demanding an immediate response, tends to work better than direct pressure.
Question: What stage of change involves someone not yet recognizing they have a substance use problem?
Answer: Precontemplation is the stage where someone has not yet recognized their substance use as a problem. They may be aware of specific consequences without connecting those consequences to their use, or they may minimize the severity of what others are observing. This is the first stage in the Transtheoretical Model of behavior change.
Contemplation
Contemplation is the stage where someone has started to acknowledge the problem but has not committed to changing it. This is the stage exam questions describe as weighing the pros and cons, and that description is accurate: people in contemplation genuinely go back and forth, sometimes within the same conversation, between reasons to change and reasons to keep things as they are.
This ambivalence can last for months, and pushing someone to skip past it rarely works. What helps more is exploring the ambivalence honestly rather than trying to resolve it for them. Asking what a person would gain by changing, and being willing to sit with an answer that is still uncertain, tends to move things forward more reliably than an ultimatum. Contemplation is also the stage most associated with the familiar image of someone thinking seriously about treatment without yet having made a call.
Preparation
Preparation is the stage where intention turns into planning. Someone in preparation is not just thinking about change anymore; they are researching options, telling a few trusted people, or setting a rough timeline, often within the next month.
This stage is a narrow window. People in preparation are motivated but not yet acting, which means momentum matters more here than in almost any other stage. Concrete next steps, a specific date, a phone call already scheduled, help convert preparation into action before the motivation fades. Vague encouragement to keep thinking about it can actually stall someone who was ready to move.
Action
Action is the stage most people picture when they think about recovery: detox, entering a program, stopping use outright, or actively restructuring daily routines around the new behavior. It is also the most visible stage to family and friends, which can create pressure to treat it as the finish line.
It isn’t. Action is demanding precisely because the old coping mechanism is gone before new ones are fully established. Cravings, disrupted sleep, and irritability are common during this window, not signs that something has gone wrong. Support during action usually means practical help, structure, and patience with a person who may seem worse before they seem better.
Maintenance
Maintenance begins once a change has held for a meaningful stretch of time, generally cited as around six months, and shifts the work from starting the change to protecting it. The urgency of early recovery fades, which is exactly what makes this stage deceptively difficult: the constant vigilance of action gives way to ordinary life, where triggers show up in mundane moments rather than obvious crises.
People in maintenance still benefit from structure, even after the acute phase has passed. Continued connection to a support network, ongoing awareness of personal triggers, and honest check-ins about complacency all help sustain a change that no longer feels urgent but still requires attention.
Relapse
Relapse is a return to the previous behavior after progress has been made, and it is common enough that treating it as an exception rather than a possibility usually backfires. It does not erase the stages that came before it. Someone who relapses typically re-enters contemplation or preparation rather than starting over completely from precontemplation, because the insight gained earlier does not disappear along with the sobriety.
What matters most after a relapse is what happens in the following days. Identifying the specific circumstances that preceded it, rather than treating it as a general failure of willpower, turns the relapse into information that makes the next attempt more targeted.
Why People Move Backward, Not Just Forward
The stages of change are usually drawn as a straight line, but almost nobody experiences them that way. Movement backward, especially from action or maintenance into contemplation or relapse, is normal enough that some versions of the model represent it as a spiral rather than a line: each pass through the cycle happens at a slightly different level of insight, even when the surface behavior looks like a repeat.
This matters for how progress gets judged, particularly by family members watching from outside. A relapse after eight months of maintenance can look, from the outside, like nothing was learned. From the inside, it usually means something different: the person now has direct experience of what maintenance actually requires, which the first attempt could only guess at. The second attempt at action tends to be built on more specific, tested knowledge than the first.
None of this means relapse should be treated as harmless or expected in a way that lowers the stakes. It means that judging someone’s recovery by whether they’ve stayed permanently in action or maintenance misses how the model actually works. The more useful question is usually not whether someone relapsed, but which stage they are in now, and what that stage actually needs.
There is a quieter marker of real progress that the stage labels alone do not capture: the same trigger showing up twice, met with a different response the second time. A person who relapses after encountering a specific stressor, then later encounters that identical stressor again and manages it differently, even briefly, has moved somewhere real, regardless of which stage they technically occupy on paper. Family members watching for a clean, permanent line between “before” and “after” often miss this kind of progress entirely, because it does not look like the finish line they were expecting.
What to Do If You Recognise a Stage in Someone You Care About
Matching your response to the actual stage, rather than the stage you wish someone were in, changes how effective that response is. Someone in precontemplation needs information and patience, not an ultimatum. Someone in preparation needs concrete next steps before their motivation cools. Someone in action needs practical support more than advice.
If a person has moved into preparation or action and is actively looking at treatment options, formal programs become genuinely useful at this stage in a way they usually are not during precontemplation. Residential programs, including non-12-step options such as Siam Rehab in Thailand, are built around the action and early-maintenance stages specifically, offering the supervised, daily-routine environment that stage of change tends to require.
If someone you care about is still in precontemplation or contemplation, pushing them toward a program before they are ready to consider it rarely works, and can sometimes reinforce the resistance you are trying to overcome. In that stage, the more effective use of your energy is usually the conversation itself, not the referral.
Families often default to the same response regardless of which stage they are actually witnessing, usually because the crisis feels identical from the outside whether someone is in precontemplation or relapse. Slowing down enough to ask which stage this looks like right now, before deciding what to say or do next, tends to produce a more useful response than reacting to the moment alone.
Frequently Asked Questions
Is Relapse a Stage or Something Separate?
Both framings appear in addiction literature. Some models list relapse as a distinct sixth stage because it follows a recognizable pattern; others treat it as an event that can occur at any point rather than a stage in its own right. Practically, treating it as a stage makes it easier to plan a specific response rather than treating it as an unplanned failure.
How Long Does Each Stage Typically Last?
Duration varies significantly by person and substance. Precontemplation and contemplation can last months or years without external pressure. Preparation is usually shorter, often weeks, since it represents active planning rather than open-ended reflection. Maintenance is generally considered established after roughly six months of sustained change, though the underlying vigilance continues well beyond that point.
Can Someone Skip Stages of Change?
Not in a way that holds up over time. A person can move through early stages quickly, sometimes within days during a crisis, but skipping contemplation and preparation entirely tends to produce action that collapses back into relapse faster, since the underlying ambivalence was never actually resolved.
What Moves Someone From One Stage to the Next?
Movement is usually triggered by a specific event rather than gradual persuasion: a health scare, a relationship ultimatum, a legal consequence, or simply reaching a point where the effort of maintaining the addiction outweighs the effort of changing it. Outside pressure can accelerate this shift, but only once the person has already begun questioning their own behavior; pressure applied during precontemplation, before that internal shift starts, tends to produce resistance instead.
