"This could be handled as a multivariate repeated measures as well, using time for the repeated factor and DV for the multivariate test. As David suggests, see the GLM procedure."

I do not find Hotelling's T in the repeated measures section. I did find Hotelling's Trace in the multivariate GLM section (not repeated). Could I "trick" SPSS by defining my 9 variables as DVs, and time as factor (using a long version of the data)? And what exactly is Hotelling's Trace? Can I report this as statistic in a paper: "Hotelling's Trace = xxx, P<.001. This means that the means of all items differed from t1 to t2."?

Thank you
