It's actually inverted for self sufficency (it's worded bad), the lower the score, the more self sufficent you are. At least, that was my interpretation because I am a very self-sufficent person (at least I try to be at all costs).
I find this test to be interesting. People automatically assume that any form of narrcissim is a bad thing. I could see some people scoring very high on this that aren't narcissist, and some that would score low that are. Also, having a very low score would be good in some cases, but it could also be a sign of low self esteem. That's the other end of the narcissim spectrum.
