The course will present a primer on the diagnosis and management of depression for the general psychiatrist, primary care physician, or nurse practitioner. The course is designed in a scalable model. This means that each lecture builds upon the previous one, paralleling the thought process that psychiatrists follow when facing a patient with increasingly resistant depression. Participants may follow the course as far as they wish, based on how much they are interested in doing in their practices. Participants will get a complete, self-contained lesson in each lecture, permitting them to either view the entire course (in any order desired) or select which module(s) they wish to view. The lectures will include at least one case presentation, played by two of the DCRP faculty where one will play the doctor and the other will play the patient.
