Stepwise Regression Help

#1
Hi,

Statistics is not my strong suit and I could really use some help. I'm wondering if it is possible to do a stepwise regression with 9 IVs on a dependent variable that is made up of 3 subscales. My question is: Can I do a stepwise regression on each subscale of the dependent variable, or can I only do a stepwise regression on the total score of the dependent variable? Many thanks in advance for your help!
