I agree. Personally, I think that psychiatrists and psychologists should work collaboratively whenever possible, including psychopharmacology, as each discipline complements the other.
The fact that you find this issue to be legitimate concern is consistent with how most of psychiatry feels (exceptions include most folks on this board). You should have heard some of the psychiatrists lobbying against psychologist RxP in recent legislative sessions! At the same time, it's really not an issue to get too concerned about, as psychiatric NPs have not put psychiatrists out of business, and only a minority of psychologists will likely pursue RxP. Many, in fact, are against this added scope of practice.
I am currently in my third year of medical school, and I support psychologist RxP, as psychiatry is simply not putting out the numbers to meet the need for psychopharmacological treatment. Plus, I value the biopsychosocial approach to psychiatric care that, in my opinion, is sorely missing in modern, pharma-dominated psychiatry.
Feel free to post in the clinical psychology forum. There's a thread there on psychopharmacology/advanced practice psychology. Folks there would be happy to hear your thoughts about this issue. Though I do not think we're off-topic here.
