If I've understood correctly, you have 24 pairs of measures per person, so your data could look like: Trait Person Possession Desirability 1 1 4 5 2 1 1 4 3 1 7 5 4 1 6 3 ... 24 1 5 2 ... 1.. 59 4 3 ... 25 59 1 6 If they don't, you'll be able to make them look like that with by using the transform -> reshape option. If that's right, use split file to estimate the correlation for each person. Then use the Output Management System (OMS), which lets you take output and turn it into data. You'll need to fiddle around to do that. Then run the standardization (which is in descriptives), with (I think) split file on again. SPSS isn't designed for weird data structures like this - it's sometimes easier to fiddle with the data in a program that is more flexible, I tend to use either R or Excel.
