Hello everyone!

A psychiatrist I visited this week comissioned a MMPI-2 test to see and confirm if I have any personality disorder. I spent a few weeks at a mental ward last year in a different country and the doctors there hinted that I may be borderline but they cannot give me a full diagnosis (don't know why but I guess it could be the country's laws). 

Just want to ask what would the personality test entail? I read some information about it but couldn't understand much. 

How is it supposed to give a concrete diagnosis and not a false one? Have you taken this test before?

:)
