A focus group of New York City adolescents was conducted 21 months after the September 11, 2001, terrorist attacks to examine their emotional responses to the incidents. The adolescents had vivid memories of the attacks and articulated their reactions, their perspectives on the potential motives for the attacks, and their concerns about ongoing danger. Impressive was the maturity and thoughtfulness of their discourse, which revealed their efforts to process and integrate the events and a realization that their world had changed.
