At which stage does a client recognize they have a problem and begin planning for change?

The correct choice signifies the distinct stage in the change model where a client acknowledges the existence of a problem and actively starts to develop a plan to address it. This stage is critical as it reflects the client's readiness to move beyond awareness and begin strategizing actionable steps towards change.

During the Preparation stage, individuals not only recognize their issues but also start gathering information, setting goals, and deciding on specific techniques or behaviors they will adopt to facilitate their change process. This proactive planning is essential as it lays the groundwork for the subsequent Action stage, where the client begins to implement their plans.

In contrast, other stages of the change model serve different purposes. The Contemplation stage involves recognizing a problem but stopping short of making a concrete plan, while the Action stage is about executing the strategies developed in the Preparation stage. The Maintenance stage focuses on sustaining the changes made and preventing relapse rather than planning for change. Thus, the characteristics of the Preparation stage reflect a commitment to change that distinguishes it from the other phases.
