Does SPSS provide an internal consistency measure for ordinal variables?

Troubleshooting


Problem

I'm using SPSS for data analysis on a set of variables with data that is measured on an ordinal scale.. I'd like to calculate an internal consistency reliability coefficient and the research I've conducted highlights some of the problems with using coefficient alpha for ordinal data. Which is the correct statistic to use in SPSS to calculate the reliability coefficitent for ordinal (rank based) data?
