During which stage of the Transtheoretical Model should actions to motivate change be taken?

The correct choice is focused on the stage of Maintenance within the Transtheoretical Model. In this phase, individuals have already made significant changes to their behavior and are working to sustain those changes over time. Motivation is crucial during this stage because it helps to reinforce the new behavior and prevent relapse to old habits. Therefore, actions taken to motivate change are most effective at this point, as the individual is attempting to solidify their commitment to the new behavior.

In contrast, during the Action stage, individuals are actively engaged in making the behavior changes but may still require support and reinforcement. The Contemplation stage involves thinking about change without yet taking action, while in Precontemplation, individuals may not recognize the need for change at all. Hence, the focus on motivating change is most critical in the Maintenance phase, where consolidation of the behavior is vital for long-term success.
