Interesting problem.

It would be useful if you show us this questions and this 5 lickert scale points. Just to have an idea of the information you are gathering.

On the other hand, I dare say I think your problem is not a "statistical" one. In a regression analysis, you could relate any two variables (or more) and the test could be in favour or against your hypothesis. Having this in mind, you could use a variable as a "core" of "success". For example, you may state with non-statistical fundaments that success can be asociated to quantity of visits. Well, there you have a core variable and more visits mean more success. If you relate that variable to the factors you are measuring, a regression analysis will be easy to be set.

You may do a "discriminant analysis" to understand which factors are those which determine success from a set.

I do not know if I've been clear enough. My english is still quite bad.

I hope I can help you with this.
