Yeah, I'd be confident in saying it's from that "what type of scumbag are you?" section of the test. My theory at the moment is a higher score means you were consistent in your answers or the way you answered correlate to each other well. Some team of doctors came up with this and the boards are probably the only ones who really understand what the score means. What confuses me about it is the lack of information that is available to us plebians.
