To get back to the original topic as this has digressed a bit. I am wondering why the OP would be surprised to find inept practitioners. I have worked with quite a few psychiatrists where I question their competency. My biased perspective has always been that they are not as competent as the average physician. Participating in this board has changed my perspective on that, my fear is that you guys are the exception. Of course, one of my supervisors pointed out that I didn't trust my colleagues in psychology very much and she was right because I hear too many stories of incompetence. I could give example after example from both professions. Psychologist who told my sister-in-law that she was likely a victim of satanic ritual abuse because she had difficulty remembering childhood, psychiatrist who prescribes stimulants to kid with anxiety due to sexual abuse and testifying against the perp, psychologists and psychiatrists who work with kids but have no ability to develop rapport and just have painful awkward sessions (this happens all the time, especially with adolescents), psychiatrists who prescribe benzos to substance abusers, team of psychiatrists who agreed ECT was best treatment for Borderline. Psychologists and psychiatrists who take sides with their patients and begin doling out advice about how to deal with people they have never met. I would think disagreement over diagnosis ranks pretty low down the list.
As a patient I can really relate to what you've written here. Aside from my current Psychiatrist (who really has turned out to be just an absolute godsend for me), in the 20+ years I've been in and out of the mental health system in South Australia I've had maybe 2 Psychologists and 1 basic Therapist who I can honestly say provided me with a good level of care and even then that was only for one specific issue, Borderline PD. Credit where credit's due those Psychologists and Therapist did provide me with enough of a solid treatment basis that the Borderline PD diagnosis was eventually able to be taken off the table, but in terms of my other issues/symptomology up until recently I've pretty much just stumbled from one treatment disaster to another. There was the Psychiatrist who diagnosed me with Schizophrenia after just 45 minutes, when the majority of that time was spent on taking my history not discussing the current symptom presentation (at one point I mentioned a childhood diagnosis of ADD, which I described as being like having a filing cabinet in my head with everything just thrown in at random, and when I managed to sneak a quick look at my notes while she was out of the room she had seriously written down, "Patient has delusions of filing cabinet in head" - Um hellooo, I was using a metaphor!

); the Psychiatrist who snoozed his way through the majority of my first session whilst sporting an exceedingly noticeable erection; the Psychiatrist who, not even 15 minutes into the session, suddenly turned around and said "you're full of ****, get the f*** out of my office" (his exact words, and to this day I still have no idea what I said or did to have triggered such a response); the Psychiatrist who over turned a diagnosis of Anorexia Nervosa, previously given to me by one of the Professors at the state's main out patient eating disorders hospital treatment unit, and despite my presenting as clinically emaciated at the time, based solely on the fact that I buttered my half slice of toast in the morning and sugared my tea and coffee; the radical separatist feminist Psychologist who blamed everything on men and the patriarchal system of oppression; the Psychiatrist who basically turned out to be a sexual predator with a medical license and very graciously left me with a nice little package of trauma and trust issues that I'm still working through more than several years after the fact (yeah, thanks for nothing, a-hole

)...
But then having said all that I see my Psychiatrist now, or I come on here and read some of the posts by awesome treatment providers/researchers like yourself, Whopper, Fonzie, OldPsychDoc, Billypilgrim, Nitemagi, Erg923, and so many others, and suddenly I'm seeing a vastly different side to mental health care - one that I honestly thought just barely even existed, and it makes me wonder 'well where the hell ARE all the good Doctors/Therapists out there, what is so wrong with mental health overall that coming across even a handful of (more than) decent practitioners feels tantamount to wandering outside and finding a Unicorn just randomly standing there?' And more to the point, what can be done to fix it? Not just in terms of better liaisons between different groups of practitioners (Psychiatrists, Psychologists, etc), but with everything.
