Personality Disorder Test - Take It!
Actually, it's probably best if you don't if you're anything like me. Andy wanted the link though. Victor Lams took it and diagnosed himself as boring, whereas I just worried myself by achieving "moderate" results in a fair number, which should be fine. Got a "high" for obsessive-compulsive though. Um, hooray.
N.B. I'm copied their code for the link; I don't really think you should "Take It!". I'm shocked that anyone thought I would create a link with such arbitrary capitalizations in fact.
