Final answer:
Individuals in the preparation stage are the most likely to become PT clients because they are ready to take steps towards behavior change and may already be making preliminary arrangements for therapy.
Step-by-step explanation:
People in the preparation stage are most likely to become a physical therapy (PT) client. This stage involves individuals who are intending to take action in the imminent future, and they may begin to take small steps towards behavior change. For example, if someone is dealing with an injury and recognizes the need for rehabilitation, they might be researching different physical therapy options or planning to schedule an appointment with a therapist, which reflects the characteristics of the preparation stage.
In contrast, individuals in the precontemplation stage are not considering change at all, while those in the contemplation stage are only thinking about change but are not ready or sure about making the changes. Once action is taken, such as attending physical therapy sessions regularly, the individual moves to the action stage.
