Which set lists the stages of the Transtheoretical Model (TTM)?

• A. Unawareness, exploration, adoption, saturation
• B. Precontemplation, contemplation, preparation, action, maintenance
• C. Knowledge, awareness, acceptance, compliance
• D. Initiation, growth, maturity, decline

Answer: (B)

In the Transtheoretical Model, behavior change unfolds as a person progresses through stages of readiness: precontemplation (not yet considering change), contemplation (aware a change is needed and weighing options), preparation (getting ready to change with concrete plans), action (actively making the behavior change), and maintenance (sustaining the change over time and preventing relapse). This sequence precisely locates how someone moves from no intention to change to long-term adherence, which is why that set of stages is the best fit. The other sets use terms that don’t map onto the personal change process—one describes a general lifecycle or adoption path, another uses generic knowledge/acceptance/compliance terms, and the last follows product-like lifecycle stages—so they don’t reflect the stages of readiness and maintenance central to the model.
