Sheesh. And you say I'm the angry one.
You do not have data supporting its effectiveness. You have an absence of data of malpractice claims. Which is not the same thing.
Your listing of psychological testing is completely irrelevant. No standardized testing replaces a skilled clinical exam. Nor do I have need or desire to do testing to diagnose a patient.
I do not have biases against psychologists per se. I have biases against anyone using the term "doctor" in a hospital setting, where it implies expertise not present. Same issue I would have with a DNP or Doctoral physical therapists. Patients don't know the difference.
You may have had some lecture once on ordering an EKG, but RxP doesn't give you enough training to understand the underlying anatomy and physiology of how the heart functions, and thus no real foundation to understand the EKG. You may be able to look at some numbers and say "that's not normal," but that's not sufficient. And prescribing medications that change heart conduction properties (from antidepressants to antipsychotics) without understanding that is asking for trouble. Now you may never get sued, because as I've pointed out before the main factor that has been proven time and again to moderate malpractice is a good treatment relationship. And people tend to like their therapist. So they'll overlook errors. And you may skate by thinking you're doing a bang up job. That isn't the same as giving quality or safe care. Because you're completely unaware of every close call you cause.
You again conflate the issues as if I have a bias against psychologists. I do not. I have issue with psychologists practicing medicine without the proper training. As skilled as a psychologist may be in understanding mental illness, there is nothing about that that generalizes to medical expertise or understanding anatomy, physiology, psychopharmacology, pathology, or any number of other areas. It just isn't there.
You want some evidence against RxP?
How about the DoD program costing 6.1 Million Dollars to produce 10 psychologists, and no improvement in access. Even the GAO showed it was not cost effective.
http://onlinelibrary.wiley.com/doi/10.1002/jclp.10052/abstract
The DoD program went on for 7 years, with each trainee being directly supervised by a
Psychiatrist, which current training programs cannot claim. Even WITH that level of supervision for that many years, the final report noted "While their medical knowledge was variously judged as on a level between 3rd or 4th year medical students, their psychiatric knowledge was variously judged as, perhaps, on a level between 2nd or 3rd year psychiatry residents."

Now who would like their medications and problems being handled by someone with the knowledge of a medical student even after 6-7 years of additional post-graduate training? Doesn't sound safe to me. In fact there is SUBSTANTIAL evidence from the Institute of Medicine that level of training is associated with more medical errors (less training-->more errors). It's quite ridiculous that the training of psychologists somehow shields them from medical errors, considering they know even less about all of medicine and even of citing emergencies in general.
You really believe psychologists inherently can handle such medical treatment. The evidence speaks against that. In fact it tends to show that psychologists OVERESTIMATE their own competence and knowledge of medications, and their ability to handle them.

Certainly nurses must think it's a good idea that psychologists get prescription rights. No? Wonder why? Allow them to elaborate and you can see that it isn't just physicians that think this is a safety risk.

How about some other scholarly critiques?
http://www.ncbi.nlm.nih.gov/pubmed/16396524
Which mentions the geographic location of psychologists doesn't lead to improved need. Nor is there ANY evidence aside from 1 study supplied by the APA, to show that there is such an undersupply that requires adding a scope of practice to those that don't have it, NOR is there any evidence to show that such a need could not be met otherwise.
All of this further bypasses what many identify as the real reason for RxP -- pursuit of expanded practice to maintain the viability of a profession (psychology) being oversupplied by too many schools, and with reduced need with the increase of masters level therapists.
If you really think I have something against YOU, then you really think too much about yourself. I could care less. And your pointing at me and calling Me narcissistic I only find humorous. Being able to practice medicine is a privilege. One I take up with humility, recognizing that I am not perfect, people are complex, and that I must struggle to continuously improve my knowledge base. I don't think skating by with 400 hours or didactics takes seriously enough the complexity of human physiology and pathophysiology, and moreso just demonstrates hubris.
And even amongst all of this, you still can't admit there are deficits in your knowledge or training. You have to be someone "good in many things." Arrogance.
