Hey there! I'm happy to touch on what I know regarding this topic. Disclaimer, I am a Duke Psych resident. It was my first choice and I would eagerly choose Duke again. You will work hard but learn a tremendous amount of material and have an absolute blast while you do it. My experience has been one of tremendous support, education, enthusiasm and I am truly happy resident. Duke psych is very well respected in the hospitals and our relationship with surgery, medicine, ER etc is one of mutual love. This was something that stood out to me about Duke compared to other places when I came. At Duke, you work at Duke Hospital, the Durham VA med center (across the street from Duke), Duke Regional Hospital, NC state Psychiatric hospital, and a multitude of outpatient clinics in Durham in your 3rd and 4th year. The training in psychopharm, neuropsychiatry, addiction, psychotic disorders, all arrays of mood disorders, family studies, therapy, motivational interviewing, child and adolescent, and the list goes on and on, is excellent. Thursday 8am-1pm is reserved academic half-day for residents. When you go on interviews for residency and when you talk to residents in other fields, you will see how rare and special this half-day of learning is. Im currently on an off-service rotation and am still able to attend these academic half-days. They work very hard to make every rotation a quality learning and doctoring opportunity.
The rest of my reviews about the other programs will be positive as well, because I actually did like all the other places I went, just like Duke the best.
Regarding Emory, I think its a great program - seems very therapy oriented, which is great. They have a really cute department building that had charming trees, etc around it - but its still on hospital campus, so yay. The program residents seemed very happy. All my communications with the program director were positive. Atlanta is a sweet city (a bit congested with traffic, but very cool indeed). Grady hospital gives exposure to an intense and interesting set of pathologies.
UNC: I love Chapel hill as a city - i live in chapel hill, but work at Duke. Takes 12-15 minutes drive to get to Duke. UNC campus is beautiful. The hospital is beautiful as well. The program seemed very warm, happy and close-knit. The residents seem to work just as hard as we do at Duke, so if you're going for an easy program, UNC and Duke are not for you. The triangle - Raleigh, Durham, Chapel Hill, is very heavily populated and UNC and Duke work hard to fill this need for mental health care - and this isn't even counting the patients who are transferred from surrounding states. Anyways, the UNC residents seem very talented and well trained. They seem to get more Child Psych exposure in their 1st and 2nd year than we do. Their second year of residency is outpatient, which seems cool and most people seem happy with it.
I ended up canceling interviews to UVA, MUSC, Vanderbilt because I felt that between Duke and UNC, I had found my fit.
