What term refers to the ability to stick to a change for six months or more?

Maintenance refers specifically to the ongoing process of adhering to a behavior change for a sustained period, typically six months or longer. In the context of health behavior change, maintenance signifies that an individual has not only made a change but has also successfully integrated it into their daily life, thereby demonstrating sustained commitment and stability in that behavior. This step is critical in various health behavior theories, such as the Transtheoretical Model, which outlines the stages of change individuals go through when altering health-related behaviors.

The other options represent different aspects of the behavior change process. For instance, making the change refers to the initial step of implementing a new behavior, while self-efficacy involves an individual's belief in their ability to carry out the necessary actions to make the change. Action denotes the active engagement in the new behavior but does not encompass the long-term aspect of maintaining that behavior beyond the initial phase. Therefore, maintenance is the term that accurately captures the successful and ongoing application of a behavior change over a considerable period.
