I am not a psych resident, but was considering it for a while.....I contacted several programs all over the country and asked if they accepted COMLEX and if they ever had DOs in their program. I got an overwhelmingly positive response. I believe only a couple of the CA schools would not accept COMLEX. If psych is your passion, you should not have a problem getting a residency.....I would advise you to contact the programs you are interested in and ask if they accept the comlex (if you have not taken USMLE) and if they have ever had any DOs in their program, etc.
