Subject: teenager behavior
Answer: I would suggest two search engines first google the topic of adolescent behavior or studies on adolescent behavior or go to www.findarticles.com and do the same. There are more articles out there than you can begin to imagine.
Was there something specific about teen behavior you were looking for? Sometimes answering this question will narrow your search and find you more reading than just a broad topic like teen behavior.
Hope this helps!
