ok that test is aloud of bollox and here is why.
if you look at the questions they are all diagnositc critirea of some kind or other for a personality disorder, without anything neutral.
all the questions are negative and there for it is already bias.
also sometimes behaviour can be circumstancial, maybe in some situations but not others.
ive done this test before ages ago, and ive been screened for disorders, and i dont have any yet this site seemed to think i had several lol
dont read into it. notice how theres 'help' adds next to the results. the site wants ur money not to help you out.
if you want a true personality test try
