I mean, I have one selection variable and one dependent variable. Can I do a factor analysis with them? in SPSS, I need to put at least two variables in variables section (with one variable in the selection variable section). Looking forward to hearing from you.

I agree with Injektilo. You possibly could do this. Why would you want to? Normally you want many (30 plus say) variables before doing EFA (there are actually rules of thumb that sugest how many you need, but they generate signficant numbers regardless).

EFA is a data reduction method and when you have a two variables there is no reason to use it. Do you mean by any chance SEM (structural equation models)? Usually they are not called FACTOR ANALYSIS. Even with that approach I can't see using two variables.

Why not simply do regression?
