Hi Mr. Dommeyer!
Kuder-Richardson 20 is a special case of Cronbach's alpha for binary
variables. So you can use the reliability module in SPSS for your analysis.

Subject: Reliability Analysis with Nominal Data
Hi:
I asked this questions a few days ago but got no response. Hopefully today
someone will be inspired to respond.
I have a ten item scale where each item allows for three choices. The
choices are coded 1, 2, & 3, and represent nominal data. Each item has
one "correct" answer where I award a point to the respondent. If the
"correct" choice is not marked, no points are awarded. A respondent can
score from 0 to 10 on this scale. From what I understand, I can't
"legally" perform a reliability analysis on this scale (similar to a
Cronbach's alpha). Am I right or wrong?
