Kappa is one standard measure of disagreement among raters. A google search on "multiple raters" and "kappa" will turn up references which show that an intraclass correlation is equivalent to a generalized kappa statistic. Then a search on "intraclass" and "stata" will lead you to the appropriate stata command.

I have three variables: A, B, and C. They are individual
assesssments of the
same phenomenon on a scale from 1 (poor) to 5 (very good).
The data looks
like:

id        A    B    C       DS
1        4    4     4        0
2        3    4     4        1
3        5    2     3        ?
4        2    2     4        ?
and so on.
