Multiple ordinal response regression-HELP!


I have a data of 50 medical residents from 3 specialities. Every resident had to diagnose a X-ray image and rate their level of confidence in the diagnosis on an ordinal scale: 1-25%, 2-50%, 3-75%, 4-100%. I also collected their seniority (junior or veteran resident).

I'm looking to perform a regression where the dependent variable is actually the 24 columns of confidence levels (one column for each x-ray).

I can't find a way to do so in SPSS.

Any help would be much appreciated!!!
