During which stage do individuals spend time thinking about their problem?

The correct option is indeed the stage of contemplation. During this phase, individuals actively engage in thinking about their problems, weighing the pros and cons of their behavior and the potential need for change. This stage is characterized by increased self-awareness; individuals begin to recognize their issues and consider the possibility of making a change but are not yet committed to taking action.

While they may still feel ambivalent, this stage serves as a crucial turning point where contemplation can lead to motivation and readiness to move toward the preparation stage. It highlights the significance of introspection and self-examination in the journey toward addressing and overcoming substance use issues.
