Re-posting my last question for Roger, in case it went unnoticed by the later discussion. Thanks.

Yes, that really helped and I am quite thankful. But as I did a little more research on Somers' D, I came across this information that said the two variables need to have a monotonic relationship for the somersd results to be valid. Is that true? I checked my variables for monotonicity using the Spearman test and they do not have a monotonic relationship (the Spearman's values were very low). Can I still use the somersd estimation? If not, is there something I can do to still use the somersd estimation? Thank you very much.

Dear all,
I am using the somersd command to investigate the probability of having higher social participation for the beneficiaries with respect to the control group.
The social participation is represented by two variables: Have you done/would you Voting at local elections, categorized as 'Have done', 'Might do' and 'Would never do';
and How much do you trust the following institutions from 0 to 10.
My question is: is it a good practice for me to use the Somers’ D test for both variables?
According to the replies of Roger and Raju I would say yes, however reading the papers suggested by Nick I seen that all variables in those papers are continuous.

Thank you very much for your help.
