The September 11, 2001, terrorist attack on the World Trade Center profoundly affected the population of New York City, including analysts and analysands. To study the effect of this event on the technique of psychoanalysts conducting ongoing analysis during the weeks after 9/11, confidential questionnaires were sent to all candidates and faculty at the Columbia University Center for Psychoanalytic Training and Research. Respondents indicated that in the days and weeks following 9/11 they initiated phone calls to their analysands, asked about their analysands' families, gave advice when it was requested, offered reassurance, and answered personal questions. They did not initiate physical contact, discontinue use of the couch, or give unsolicited advice. These responses suggest that these analysts made decisions to alter their technique in certain ways in the wake of a catastrophic event shared by the community.
