Why do some people quit smoking on their first try while others “think about it” for a decade? Psychologists James Prochaska and Carlo DiClemente asked exactly that in the late 1970s — and their answer became the stages of change model (the Transtheoretical Model, or TTM), one of the most influential frameworks in behavior-change psychology.
The core insight: change isn’t a single decision — it’s a process with stages, and the strategies that work depend on which stage you’re in. This guide walks you through all 6 stages with real-life examples, what to do in each stage, the 10 processes of change, and an honest look at the model’s criticisms.
Whether you’re trying to quit smoking, start exercising, eat better, sleep more, or be more productive — the stages work the same way. Find your stage below, and you’ll know exactly what to do next.
The 6 Stages of Change at a Glance
| Stage | Mindset | Timeframe |
|---|---|---|
| 1. Precontemplation | “I don’t have a problem.” | No intention to change in the next 6 months |
| 2. Contemplation | “I should probably change…” | Intends to act within 6 months |
| 3. Preparation | “I’m getting ready.” | Intends to act within 30 days; taking small steps |
| 4. Action | “I’m doing it.” | Active change for less than 6 months |
| 5. Maintenance | “I’m keeping it up.” | Sustained change for 6+ months |
| 6. Termination | “It’s just who I am now.” | Zero temptation; complete confidence |
Stage 1: Precontemplation — “Not Ready”
In precontemplation, there’s no intention to change in the foreseeable future (the next 6 months). People here may be unaware their behavior is a problem, under-informed about consequences, or demoralized by past failed attempts.
Example: Someone who smokes a pack a day and says “my grandfather smoked and lived to 90” — genuinely not considering quitting.
What helps at this stage: not pressure, but consciousness-raising — gentle information, personalized feedback, and emotional stories. Confrontation backfires; curiosity works.
Stage 2: Contemplation — “Getting Ready”
The person recognizes the problem and intends to act within the next 6 months — but they’re ambivalent, weighing the pros and cons. People can get stuck here for years (“chronic contemplation”).
Example: “I know I should exercise — I keep reading about it, I feel guilty, but I haven’t started.”
What helps: decisional balance exercises — honestly listing the pros and cons of changing. Progress happens when the pros increasingly outweigh the cons. Self-reevaluation also matters: imagining the person you want to become.
Stage 3: Preparation — “Ready”
Now there’s intention to act within 30 days plus small behavioral steps: buying running shoes, setting a quit date, cutting back, telling friends about the plan.
Example: “I’ve joined a gym, told my partner I’m starting Monday, and meal-prepped for the week.”
What helps: self-liberation — making firm commitments, setting specific dates, and building a concrete plan. This is the stage for planning, not just thinking.
Stage 4: Action — “Doing It”
The person has made overt behavior modifications — but for less than 6 months. This stage demands the most time and energy, and carries the highest relapse risk.
Example: Three months smoke-free; going to the gym four times a week for two months.
What helps: behavioral strategies — counter-conditioning (substituting healthy alternatives), stimulus control (removing triggers), reinforcement management (rewarding the new behavior), and helping relationships (support groups, accountability partners).
Stage 5: Maintenance — “Keeping It Up”
The change has been sustained for more than 6 months. The work shifts from making the change to preventing relapse and consolidating the new behavior into a lifestyle.
Example: A year into regular exercise; the habit now feels like “just what I do.”
What helps: continued stimulus control, ongoing support, and planning for high-risk situations (holidays, stress, travel). Confidence (self-efficacy) grows as temptation fades.
Stage 6: Termination — “Done”
The rarely-reached final stage: zero temptation and complete confidence — the old behavior will never return. Many presentations of the model omit this stage and teach 5 stages, since termination is uncommon for addictive behaviors.
Example: A former smoker of 10 years who feels nothing walking past a cigarette display.
Relapse: The Spiral, Not a Straight Line
Relapse is not a stage — it’s a recognized event. The model is explicitly cyclical: people slip back to earlier stages and re-enter the process. This is normal, not failure.
Research on smoking cessation found most people cycle through the stages several times before succeeding. Each cycle teaches something — the next attempt starts from a wiser place.
| If you relapse from… | You typically return to… |
|---|---|
| Action | Contemplation or Preparation |
| Maintenance | Preparation or Action |
The takeaway: a slip doesn’t erase progress. The model expects it — plan for it.
The 10 Processes of Change
These are the strategies that move people between stages. Cognitive and emotional processes dominate the early stages; behavioral processes dominate the later ones.
| # | Process | What it means | Best stage |
|---|---|---|---|
| 1 | Consciousness-raising | Getting the facts — information, education, feedback | Precontemplation |
| 2 | Dramatic relief | Feeling it — fear about consequences or hope from others’ success | Precontemplation |
| 3 | Self-reevaluation | New self-image — the healthy behavior becomes part of identity | Contemplation |
| 4 | Environmental reevaluation | Noticing your effect on others | Contemplation |
| 5 | Social liberation | Noticing society supports the healthy choice (e.g., smoke-free laws) | Contemplation |
| 6 | Self-liberation | Committing — believing change is possible, making the pledge | Preparation |
| 7 | Helping relationships | Social support for the change | Action |
| 8 | Counter-conditioning | Substituting healthy alternatives for unhealthy ones | Action |
| 9 | Reinforcement management | Rewarding the new behavior, removing rewards for the old | Action |
| 10 | Stimulus control | Removing cues for the unhealthy behavior, adding cues for the healthy one | Action / Maintenance |
Which Stage Are You In? A Self-Check
Answer honestly for one habit you want to change:
- “I don’t see a problem” → Precontemplation. Start with information, not action plans.
- “I know I should, but…” → Contemplation. List your pros and cons; visualize your future self.
- “I’m planning to start soon” → Preparation. Set a date, gather resources, tell someone.
- “I’ve started” → Action. Restructure your environment; get support; reward progress.
- “I’ve kept it up for months” → Maintenance. Plan for high-risk situations; keep support active.
Stage-Matched Strategies: What to Do in Each Stage
| Stage | Do this | Avoid this |
|---|---|---|
| Precontemplation | Learn facts; hear others’ stories; get feedback | Shame, ultimatums, aggressive goal-setting |
| Contemplation | Weigh pros/cons; imagine your future self | Rushing into action before you’re ready |
| Preparation | Set a date; make a plan; gather tools; announce it | Vague intentions (“someday”) |
| Action | Change your environment; get support; substitute behaviors | Relying on willpower alone |
| Maintenance | Plan for triggers; keep routines; celebrate milestones | Assuming you’re “cured” and dropping support |
Real-Life Examples Across Habits
Quitting Smoking
- Precontemplation: “Smoking relaxes me; I’m fine.”
- Contemplation: “My cough is getting worse… maybe next year.”
- Preparation: “I’ve set a quit date, bought nicotine patches.”
- Action: “Two months smoke-free.”
- Maintenance: “A year clean; I avoid the smoking area at work.”
Starting Exercise
- Precontemplation: “Exercise is for other people.”
- Contemplation: “I keep thinking I should join a gym…”
- Preparation: “Bought shoes, scheduled 7 AM workouts.”
- Action: “Working out 4×/week for two months.”
- Maintenance: “It’s been a year — it’s just my routine now.”
Eating Healthier
- Precontemplation: “I eat what I want.”
- Contemplation: “My cholesterol report scared me.”
- Preparation: “Meal-prepped for the week.”
- Action: “Three months of balanced meals.”
- Maintenance: “Healthy eating is automatic now.”
Decisional Balance and Self-Efficacy
Two concepts power the model:
- Decisional balance: the mental scale of pros vs. cons of changing. Early on, cons dominate; as people progress, pros increasingly outweigh cons. If you’re stuck, the scale is balanced — tip it with honest pros.
- Self-efficacy: your confidence in maintaining the change across tempting situations. It grows with each small win — which is why starting small (Preparation → Action) beats heroic leaps.
Applications: Where the Model Is Used
- Smoking cessation: the model’s birthplace — most stage-based research started here.
- Addiction treatment: alcohol and drug programs use stage-matched counseling.
- Weight management and exercise: fitness coaching and health programs.
- Healthcare: the CDC and UK NHS have used TTM frameworks; also applied to medication adherence and stress management.
- Therapy and coaching: therapists “meet clients where they are” instead of pushing action prematurely.
- Organizations: applied to workplace and organizational change initiatives.
How Therapists and Coaches Use the Model
The model’s greatest practical value is in matching the intervention to the person:
- A therapist won’t hand an action plan to a precontemplator — they’ll explore ambivalence first (motivational interviewing pairs naturally with TTM).
- A coach working with a contemplator focuses on decisional balance and vision-building, not workout schedules.
- With someone in Action, the work becomes environmental: removing triggers, building routines, arranging accountability.
- The classic mistake — in therapy, coaching, and self-help alike — is pushing Action strategies on someone in Contemplation. It creates resistance, not change.
Stages of Change in the Workplace
The model also applies to organizational change:
- Precontemplation: “Our process works fine” — leadership sees no need to change.
- Contemplation: “Competitors are pulling ahead…” — the case for change builds.
- Preparation: pilots, budgets, and timelines get created.
- Action: rollout begins — the highest-effort, highest-risk phase.
- Maintenance: new processes become “how we do things.”
Managers who skip stages — announcing a transformation to a precontemplative workforce — get the organizational equivalent of resistance. Meeting the team where they are works better.
Criticisms: An Honest Look
The model is influential — but not uncontroversial:
- Arbitrary boundaries: the cut-points (6 months, 30 days) are somewhat arbitrary lines drawn on continuous variables like intention and time.
- Mixed evidence: Cochrane systematic reviews (2003, 2005, 2010) found stage-based interventions were no more effective than non-stage-based ones for smoking cessation.
- “Put to rest” debate: researcher Robert West argued in 2005 that the model should be abandoned, sparking a long academic debate.
- Ignores social context: income, environment, and social pressures shape behavior as much as individual “stages.”
- Assumes rationality: real decisions are often emotional, impulsive, or constrained — not neat stage progressions.
- Measurement problems: stage-assignment questionnaires are often unstandardized or unvalidated.
Fair verdict: the stages are a useful map, not a proven machine. As a way to understand where you (or a client) stand and choose fitting strategies, the model is genuinely helpful. As a precise scientific theory, it’s shakier than its popularity suggests.
Stages of Change vs Other Models
| Model | Core idea | Difference from TTM |
|---|---|---|
| Transtheoretical Model | Change happens in stages | — |
| Health Belief Model | Perceived threat + benefits drive action | Focuses on beliefs, not stages |
| Theory of Planned Behavior | Intentions predict behavior | Single decision point, not a process |
| Self-Determination Theory | Autonomy, competence, relatedness fuel motivation | Focuses on motivation quality, not stages |
| Atomic Habits (Clear) | Small habits compound; identity-based change | Practical system; overlaps with self-reevaluation |
Frequently Asked Questions
What are the 5 (or 6) stages of change?
Precontemplation (not ready), Contemplation (getting ready), Preparation (ready), Action (doing it, <6 months), Maintenance (keeping it up, 6+ months) — plus Termination (zero temptation), which many sources omit, making it 5 stages.
Who created the stages of change model?
James O. Prochaska and Carlo DiClemente, beginning in 1977 at the University of Rhode Island. Their landmark summary appeared in American Psychologist in 1992, and their book Changing for Good in 1994.
How long does each stage of change last?
There’s no fixed duration. Contemplation can last years (“chronic contemplation”). Action is defined as lasting less than 6 months; Maintenance begins after 6+ months of sustained change. Everyone moves at their own pace — and cycles back.
Is relapse part of the stages of change?
Yes — it’s expected. Relapse isn’t a stage but a normal event: people slip back to earlier stages and re-enter the process. Most successful changers cycle through the stages several times. A slip doesn’t erase progress.
What is the difference between contemplation and preparation?
Contemplation = thinking about change within the next 6 months, weighing pros and cons. Preparation = planning to act within 30 days and taking small concrete steps (buying equipment, setting a date, telling people).
Conclusion
The stages of change offer a compassionate reframe: you’re not “failing” at change — you’re somewhere in a process. Identify your stage, use the strategies that match it, and expect the spiral: progress, slips, and wiser retries.
Start where you are. If you’re contemplating, weigh your pros and cons honestly. If you’re preparing, set the date and build the plan. If you’re acting, engineer your environment and lean on support. Change isn’t a moment of willpower — it’s a journey through stages, and every stage has its tools.
