Different theories appear to educate and guide a healthcare professional through the processes of behavior change. It should also be noted that behavior change requires the will or determination of an individual engaging in health-risk behavior and the knowledge of a healthcare professional on how and strategies to bring about this change in order to to achieve the objective of facilitating behavior change..
