Hi Catherine
Don't apologise for bombarding people with stats questions - they can
always ignore them. If you want to bombard people with stats
questions who really want to be bombarded with stats questions, you
can send them to the psych-methods list (join the same way that you
joined psych=postgrads, go to www.jiscmail.ac.uk is the easiest way).
You'll still get a reply from me, but you might get them from other
people too.
Canonical correlation is one possibility. It's kind of atheoretical
though - that is, if you know what the latent variables are, you
probably shouldn't use it. You might want to use structural equation
modelling or partial least squares analysis instead (although both of
those are pretty fiddly, and you shouldn't use them unless you really,
really have to).
Just to check: are you modelling at the item level? If you are, I'd
consider summing to the scales (maybe factor analysing first) and then
doing regression.
There's a book on canonical correlation, in the Sage LIttle Green
Books series: http://www.amazon.com/Canonical-Correlation-Analysis-Interpretation-Quantitative/dp/0803923929/sr=8-1/qid=1169484475/ref=pd_bbs_sr_1/103-7993276-3685436?ie=UTF8&s=books
. I think that Tabachnick and Fidell's book 'Using multivariate
statistics' cover it as well.
Finally, you have got the add on, you just don't realise it. It's an
SPSS syntax file, called 'canonical correlation.sps', and you'll find
it in the SPSS folder (c:\program files\SPSS, if you're using windows
with a locally installed version).
To use it, you type syntax (into the syntax editor) like this:
INCLUDE 'c:\Program Files\SPSS11\Canonical correlation.sps'.
CANCORR set1 = y1, y2, y3/
set2 = x1, x2/.
Where x1 and x2 are predictors, and y1 and y2 are outcomes (just keep
going until you've got them all). (I think I've got my x and y the
right way around - I don't have SPSS here, so I'm guessing a bit.)
