The stages of change model names a stage by one simple fact: what the person intends to do, and by when. Nothing about how much insightA person's awareness and understanding that they are unwell and need help.Read more → they show or how motivated they seem changes that. A person who says 'I know it's a problem but I'm not ready yet' is not in denial and is not lacking insight. She is in contemplation, which is exactly what the model expects that sentence to mean.

• The Prochaska-DiClemente transtheoretical model describes behaviour change as a cycle of stages, each defined by a specific stated intention and timeframe. PRECONTEMPLATION means no intention to change, conventionally within the next six months. CONTEMPLATION means seriously considering change within roughly six months, but feeling ambivalent. PREPARATION means intending to act within about a month, possibly with small preparatory steps already taken. ACTION means the behaviour has changed, for less than six months, and MAINTENANCE means the change has been sustained for six months or more, with focus now on preventing relapse.
• RELAPSE is treated within the model as a normal, expected part of the cycle rather than a failure. A person may pass through the stages, relapse, and re-enter at an earlier stage (often contemplation or preparation) several times before achieving stable, lasting change.
• A later-added, optional sixth stage, TERMINATION, describes a state with no temptation at all to return to the old behaviour and full confidence in staying changed. This is distinguished from maintenance, where some ongoing vigilance against relapse is still needed.
• Several closely related psychological concepts are commonly mislabelled as stages but are not part of the six-stage list itself. Denial is an active, often unconscious refusal to accept known facts, distinct from precontemplation's simple lack of current intention. Ambivalence is the specific torn feeling that defines the contemplation stage, but is a separate concept from the stage name. Learned helplessness is a belief that change is impossible from repeated past failure, distinct from precontemplation. Cognitive dissonance is psychological discomfort that can help drive a person from contemplation toward preparation, and motivational interviewing is a clinical counselling TECHNIQUE used to help a person move between stages, not a stage itself.
• In practice, the exam question is almost always asking the reader to name the correct stage from the stated timeframe and intention. Sometimes it instead asks the reader to correctly separate a stage from one of these related-but-distinct concepts that describe the psychology happening within or around it.

• A vignette describing no current intention to change, with no active refusal of facts specified, is describing precontemplation, not denial.
• A vignette describing genuine back-and-forth feelings about changing, within roughly the next six months, is describing contemplation.
• A vignette describing small preparatory steps (buying equipment, telling others, booking help) without the behaviour itself yet changing is describing preparation, not action.
• A vignette describing a behaviour that has actually changed, but for less than six months, is describing action; six months or more of sustained change is maintenance.
• A vignette describing full confidence with zero remaining temptation to return to the old behaviour is describing termination, not ongoing maintenance.
• A vignette describing a return to an old behaviour after a period of change is describing relapse, a defined stage, not a reset to precontemplation or a sign of failure.

• Precontemplation vs denial — precontemplation is a neutral 'no current intention to change' label; denial specifically implies active refusal to accept facts the person has already been told.
• Contemplation vs ambivalence — contemplation is the STAGE label (considering change within roughly six months); ambivalence is the psychological FEELING that characterises that stage, not the stage's name.
• Preparation vs action — preparation includes small preparatory steps (buying patches, telling family) without the behaviour itself having changed yet; action means the behaviour HAS actually changed, for under six months.
• Action vs maintenance — both describe a behaviour that has changed; the six-month duration threshold, and a shift in focus from 'making the change' to 'preventing relapse', is what separates maintenance from action.
• Maintenance vs termination — both describe sustained change; termination specifically means NO remaining temptation to relapse at all, while maintenance still requires active vigilance against it.
• Relapse vs failure/precontemplation — relapse is a defined stage the model itself anticipates, not a reset to 'never intending to change' or evidence the whole process has failed.
• Motivational interviewing vs any single stage — it is a technique applied ACROSS stages (especially to help resolve contemplation's ambivalence), not itself a point on the six-stage list.
• Learned helplessness vs precontemplation — both can look like 'not currently trying to change', but learned helplessness specifically requires a history of failed attempts and a belief that change is futile.

• ⚠️ Naming 'denial' when the vignette is actually describing precontemplation — precontemplation does not require active refusal of known facts, only a lack of current intention.
• Naming 'ambivalence' when asked for the STAGE — ambivalence is the psychological feature of contemplation, but contemplation is the stage name the model actually uses.
• Calling small preparatory actions (buying nicotine patches, booking an appointment) 'action' — action requires the target behaviour itself to have already changed, not just planning steps toward it.
• Missing the six-month threshold that separates action from maintenance, and instead judging the stage purely from whether the person is 'still trying hard'.
• Treating relapse as proof the stages of change model has failed for a given patient, rather than as a stage the model explicitly plans for and expects.
• Naming motivational interviewing as if it were itself a stage rather than a clinical technique used to help move a patient between stages.

• First extract the stated TIMEFRAME and INTENTION from the vignette — this single detail almost always identifies the stage directly, more reliably than the tone or amount of insightA person's awareness and understanding that they are unwell and need help.Read more → described.
• If the vignette describes a psychological state (feeling torn, refusing to accept facts, believing change is futile) rather than a stated timeframe, check whether the question is actually asking for that separate psychological concept (ambivalence, denial, learned helplessness) rather than a stage.
• If preparatory steps are mentioned, check specifically whether the target behaviour itself has changed yet — if not, the answer is preparation, not action, regardless of how much effort has visibly gone in.
• If a duration for sustained change is given, compare it against the six-month threshold to decide between action and maintenance.
• If the vignette describes a counselling technique or clinical approach rather than a patient's own stated intention, consider motivational interviewing rather than defaulting to a stage name.
