In psychology, a client is a person who uses the services of a therapist or social service agency. And although it is often used interchangeably with patient, the term client originally evolved as a way to set apart someone seeking the services of a non-physician therapist, as compared to a physician who cares for the sick (patient). In fact, there is still some debate on whether people under a psychiatrist’s care are considered patients or clients. In almost any case, however, both are considered acceptable terms.
Example: The therapist likes to spend at least one hour with each client.
