Dear Erinn, 

I have tried to locate that you want to have without success. Here is a link with an online schizophrenia test along with scoring instructions in case it helps you.

I don't think it's a "test" as such. The papers I've seen are studies of beliefs or attitudes toward the disorder - beliefs held by members of the lay public. I think the line of research started with a 1992 article in the British Journal of Psychiatry. You say you've already tried to contact Adrian Furnham (email link below) at University College in London? You may want to try again; from what little I know of him, he is likely to be helpful but also very busy, and your message may just have gotten buried under scores of other emails. (This even happens to me, and I'm a lot less prominent than he!) The article to which I've attached a link contains the items and a description of scoring. As far as I can tell, each item is rated on a 6-point likert-type scale. It does not look like the items are intended to be added together in any way; each one measures a separate belief. So the instrument is best used for comparisons of different groups of people (e.g., members of different professions or cultures). I hope this is helpful. Good luck!

Dear  Erinn

you can fined it in MMPI Minnesota Multiphasic inventory    

Feel free to consult: "Multilevel Dynamics in Developmental Psychopathology: Pathways to the Future: The Minnesota Symposia on Child Psychology." Therein you will find the original nosology and psychometric properties needed to evaluate this tool and to interpret its scores.
