Nearly two million American teenagers are afflicted with depression, and major medical groups are now recommending that pediatricians give a simple but detailed questionnaire to all their teenage patients to try to detect this condition so that treatment can be offered.

About 1 out of 20 teens suffer from depression, which has been linked to lower grades, more physical illness and drug use, as well as early pregnancy.

Questionnaires can accurately identify teens prone to depression, plus there's new evidence that therapy and/or some antidepressants can benefit them, according to a report from the U.S. Preventive Services Task Force, published in the April 2009 edition of the journal Pediatrics .

Accompanying the task force advisory in Pediatrics is a research review saying there have been few studies on the accuracy of depression screening tests, but the tests "have performed fairly well" among adolescents. Treatment can help with symptoms of depression, say the reviewers from Kaiser Permanente and the Oregon Evidence-Based Practice Center in Portland, Ore.

But careful monitoring is vital since there's "convincing evidence" that antidepressants can increase suicidal behavior in teens, according to the Preventive Services Task Force report.

The new recommendation reverses what the task force said in 2002, when it reported that there was not enough evidence to recommend for or against routine screening of adolescents for depression.
