Which stage involves clients beginning to put change strategies into action?

The correct answer is Action. In this stage, clients actively implement the changes they have identified and planned during earlier stages. This involves applying strategies to modify their behavior, which is a crucial step in the behavior change process. Clients engage in behaviors that correspond with their goals, attempting to alter their lifestyle and habits.

Understanding the stages of change, the Action stage is characterized by commitment and effort toward making significant changes, reflecting a higher level of engagement than previous stages. This is where the theoretical preparation transitions into actual practice, allowing clients to experience the realities of their new behaviors and routines.

In comparison, the Contemplation stage involves clients recognizing that change is needed and considering the benefits of making those changes without yet committing to specific actions. The Preparation stage precedes Action, where clients have decided to change and start planning how to do so, but they have not yet begun to take action. Relapse, while an important concept, refers to returning to previous behaviors after making changes, rather than taking action toward those changes.
