Adopted Kids More Likely to Have Social Problems

Adopted children are twice as likely as biological offspring to develop mental-health disorders in adolescence, but rates are low overall, the Minneapolis Star Tribune reports. International adoptees in a group of more than 1,200 Minnesota residents had lower overall rates of the conditions than American-born children, but they were more susceptible to internalized problems such as depression, researchers said.

Rather than relying entirely on parents' impressions, "we brought them all right into our laboratories and asked the same questions to both the child and the parents," the lead researcher told Time. "That way we were able to use our clinical training to diagnose symptoms ourselves." (More parenting stories.)
