Psychological studies or articles on the Web...Where?

Question

I'm doing a research about codependency and relationships. When I search, all I get is magazine-like articles. I need to find at leat one site that talks about real studies and results done regarding this matter. I tried many search engines, still nothing. Maybe there's like a Institute or University web site I can go and start looking from there. Please!!! Help. This is for a thesis I'm working on, and I've had many problems using the search online.

Thanks!!
