Which of the following describes the stage where an individual takes responsibility for behavior change and adopts new habits?

The stage where an individual takes responsibility for behavior change and adopts new habits is accurately described by the action stage. During this phase, people actively engage in changing their behavior, implementing strategies to overcome barriers, and maintaining the momentum needed to establish new, healthier habits. This period is characterized by tangible efforts, such as exercising regularly or modifying dietary choices, reflecting a commitment to a healthier lifestyle.

In the context of progressing through a change process, individuals in the action stage have moved beyond merely considering or planning changes (found in earlier stages such as contemplation or preparation) and are now focused on making these changes a reality through practical steps and consistent efforts. This leads to significant lifestyle modifications aimed at long-term health and well-being.
