Final answer:
Behavior change imposed by external motivation, such as persuasion, typically results in transient and guilt-induced changes. Such motivation is less effective at producing sustained behavior than internal motivation, which is linked to the commitment and values of the individual.
Step-by-step explanation:
When motivation is imposed from an external source, such as persuasion, patients' behavior change is often transient and guilt-induced. This concept aligns with the understanding that externally imposed motivators can reduce intrinsic motivation, especially when rewards are tangible and the expectation of the reward is established. If, however, the reward is unexpected, intrinsic motivation may persist. This highlights the delicate relationship between internal and external motivation and the longevity of behavior change. Externally-driven changes are less likely to be internalized, resulting in a change that is not self-sustained and potentially fleeting. In contrast, motivation that comes from within an individual is more likely to lead to lasting behavior change because it reflects a deep-seated commitment and personal value alignment.
