Typical clinician-ratings used in psychiatric studies is the Hamilton rating scale, which is simply the clinician's subjective determination of your feelings. People who are taking psychotropic medications should better inform themselves as to the negative and adverse side effects of those medications. I don't usually like Breggin or the positions he takes, but I found this to be a fascinating account of the FDA workings and the actual numbers used in the Prozac trials, obtained through the Freedom of Information Act. They scared me and they should scare you too. As an informed consumer, I imagine the answer becomes clear.
Many psychiatrists are beholden to the pharmaceutical companies for their livelihood.
You don't have to be for your treatment.
