According to Miller, a person's motivation to change is influenced by which factor?

In the context of Miller's work, particularly regarding motivation and behavioral change, the most significant influencing factor is self-esteem. Self-esteem refers to an individual’s overall evaluation of their worth or value. Higher self-esteem typically correlates with a greater motivation to pursue change because individuals who feel good about themselves are more likely to believe that they can achieve their goals. This belief in their ability can drive them to take action and adopt new behaviors.

While biology, social support, and gender can certainly play roles in an individual's motivation for change, self-esteem is especially critical in shaping how a person views their capacity for making positive changes in their life. Those with solid self-esteem are often more resilient in the face of challenges, thereby enhancing their motivation to change for the better.

Therefore, self-esteem stands out as a pivotal factor influencing a person's drive to engage in and sustain personal change, reflecting both an intrinsic belief in one’s abilities and a supportive internal framework to facilitate that change.
