I also wonder if the tendency to quickly Dx for insurance reasons leads to wrong Dx? I was Dx a long time ago and given many tests, MMPI others I can't recall the names of plus a series of tests by a couple of Drs who only test for personality disorders plus observation over time in a hospital. Back then they Dx by ruling out possible Dx then eliminating those that didn't fit. For myself they were checking mostly for BPD and 2 other personality disorders all of which were ruled out. Once I was in an ER and a ER Pdoc Dx BPD but when I questioned my reg docs and T they said it wasn't possible to Dx a personality disorder in that short amount of time. Perhaps this is why they err on the side of BP over BPD, they really need more time but the insuranc companies doesn't allow time?
