If it's bugging you, find a clinical psych.

I think the idea that scizotypy is on a spectrum is not supported by the new DSM, so I doubt you will get that answered. But yes, reading that article it does seem to indicate that if you have the 4 factors you are on the psychosis end of the scale. It's always a good idea to take wikipedia with a grain of salt. Probably the articles on PC are more reliable.

But IMHO none would be as helpful as that psych and his/her tests. .
