I am also in favor of "patient". I first remember the Client vs. Patient issue being brought up in a Clincal Psychology course I took as an undergrad. At some point in the course, it was explained that there was a shift away from using the term patient in favor of client. The reason given was that it was an effort to remove the stigma associated with seeing a psychologist, or other therapist. I've never really accepted this reason as valid. I was trained as a family physician before going into psychiatry. All of the people I treated, whether for an ear infection, hypertension, diabetes or heart failure were identified as patients. I certainly don't believe any of them perceived themselves as being stigmatized by the term.
