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

<ssalbod@...>:
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?
