In the preparation stage of the transtheoretical model, what percentage of individuals tend to revert back within 21 days if they do not progress?

In the preparation stage of the transtheoretical model, it is observed that a significant number of individuals may experience setbacks or relapses if they do not move forward in their behavioral change process. Specifically, research indicates that about 50% of individuals who are in the preparation stage may revert back to previous behaviors within 21 days if they do not make progress towards action. This highlights the critical nature of this stage, as it is a transitional period where individuals are planning to take action but have not yet fully committed. If an individual remains stagnant without moving toward action, the likelihood of returning to old habits increases, emphasizing the importance of support and effective strategies during this phase.

The other percentages provided in the choices are less commonly aligned with the key findings of this stage. While higher percentages suggest a greater rate of relapse, the figure of 50% is supported by evidence, indicating that a substantial portion of individuals face challenges in maintaining motivation and momentum without observable change.
