Which process in the transtheoretical model focuses on changing the environment to influence behavior?

The process that focuses on changing the environment to influence behavior is stimulus control. This concept involves modifying the environment to promote positive behaviors or discourage negative ones. For example, removing unhealthy snacks from easy reach or placing reminders for physical activity in visible locations are strategies that reflect stimulus control.

This approach acknowledges that the environment can significantly impact an individual's ability to adhere to healthy behaviors. By altering external cues and triggers, one can create an environment that supports more desirable behaviors, making it easier to achieve health-related goals.

Other processes, while relevant to behavior change, do not specifically target environmental modifications in the same way. Self-liberation involves the belief in one’s ability to change, helping relationships emphasize the role of social support, and environmental re-evaluation focuses more on understanding the impact of behavior on the environment rather than changing the environment itself.
