Adoption Journal Articles

I am a high school student doing a project on adoption for my Families course. I've been searching for published journal articles specifically about the psychological/emotional/social effects on the child, and have been very unsuccessful. If anyone knows where I could find some, it would be greatly appreciated. If you can e-mail me, it would be better. My e-mail address is: kacey_007@mailcan.com Thank you very much (!) in advance. :-)
