It would require change, no doubt. The current PsyD is a quasi-professional degree. It's a hybrid between a PhD and a....JD/MD/DDS, whatever. In other words, it has characteristics of a PhD, but also has characteristics of a professional degree. I work with a woman who received her PsyD from either Pace or Rutgers (I really can't remember) and she told me she had to write a dissertation/doctoral paper, take a ton of stats classes, etc. That made me wonder, does she have a watered down PhD or a some kind of hybrid degree? There is no doctoral project or dissertation for the JD or MD or other professional doctorates.
So, you'd have to scap the current PsyD curriculum and make it more like other professional health care programs.
Year 1 - combination of advanced psychology and basic medical sciences
Year 2 - Same
Year 3- clinical psych, clinical med assessment and pharm
Year 4- more clinical psych, clerkships, simple research, pharm
PsyD + licensure exams, including pharmacology
2-3 year post doc residency in a medical/hospital setting
The PsyD in my world would be structured like the MD, DDS, OD, DPM, PharmD, DVM. First two years are mostly clinical/basic sciences. Third year is clinical. Fourth year is clinical and practical.
The PhD would be reserved for researchers only. IMO, a PhD isn't geared for practice. No offense to any PhD practitioners out there, but your doctorate is a research degree. Just my thoughts!
