Currently, "an estimated six percent of US teenagers are clinically depressed," with evidence suggesting that "detailed, but simple, questionnaires can accurately diagnose depression in primary-care settings." In addition, the task force emphasized that, "when followed by treatment, including psychotherapy, screening can help improve symptoms and help kids cope."

And, "because depression can lead to persistent sadness, social isolation, school problems and even suicide, screening to treat it early is crucial, the panel said." Therefore, the "group recommends research-tested screening tests, even for kids without symptoms," citing "two questionnaires that focus on depression tip-offs, such as mood, anxiety, appetite, and substance abuse."
