The problem with this test is that at least some of the questions are loaded. For instance:
Do you have a hard time throwing things away, even if they are old and worn out? They're asking if you have three hundred empty mayonnaise jars and a six-foot ball of twine, not whether you hate cleaning the garage.
Have you ever exaggerated illness or other weakness in order to get attention? This means, "Do you have hypochondria/Munchausen syndrome?" not "Did you call in sick when you really needed to get away from your psycho boss for a day?"
Have others accused you of being arrogant? They mean "everybody," not "one hypersensitive person."
Are you quiet in social situations, often out of fear of saying something stupid? Well, yes. If I've never been there before. If I don't know anybody. Aren't you?
In short, we're all prob'ly healthier than this test would have us believe.
My results are below. I believe the Avoidant flag, but I'm skeptical about the Narcissist thing.
