Jon, Thanks for mentioning SPSSINC HETCOR. Are there instructions on how I can access that procedure? Thank you. -Steve

Polychoric correlation is available in the SPSSINC HETCOR extension command - it computes Pearson, polyserial, or polychoric depending on the measurement levels of the variables.

Thanks Norberto. I thought about the polychoric, but I couldn’t find it in SPSS and I wasn’t sure if it used the ordering information. I’ll check out the link you so kindly provided. --Steve

Maybe you can find useful the polychoric correlation:

I have two columns of data made up of 10 rows, representing families. The
data in each row is the choice (Frequently (3), Moderately (2), and Rarely
(1)) made by a family member and professional about another individual.   I
am interested if there is a correlation between the two: family members and
professionals.
Does a Spearman rho provide me with this answer or is there a better test?

TIA, Stephen Salbod, Pace University, NYC
