Commitment is best represented by which question?

The question that best represents commitment is focused on intention, which is clearly articulated in the option chosen. When individuals express their intentions regarding future actions or behaviors, it reflects their level of commitment to those actions. This intention is a crucial aspect of motivation and behavior change, as it signifies a readiness to pursue specific goals and can indicate how likely someone is to follow through with those plans.

Understanding intention is essential in exercise psychology because it provides insights into where a person stands in their readiness to engage in physical activity or behavioral change. A firm intention often correlates with increased motivation and likelihood of successful adherence to exercise programs.

In contrast, the other options examine different aspects of behavior change that do not directly capture the essence of commitment. For instance, inquiries about influences or timelines address external or situational factors rather than the individual's personal intent. Similarly, questioning why someone hasn't started yet delves into potential barriers or motivations but does not pinpoint the decision to commit to an action.
