The purpose of the proposed project is to conduct a 20-year follow-up study of 182 directly-exposed survivors of the 1995 oklahoma City bombing and 181 firefighters who served as rescue/recovery workers in the disaster, and their children. The survivor and firefighter cohorts were previously assessed in early postdisaster studies by our research group. Building on successful 1-year and 7-year follow-up studies, this disaster research team now proposes to collect epidemiologic data on psychiatric symptoms and other disaster-related quantitative data and to conduct narrative interviews detailing individual experiences related to the bombing. as the only possible study with the opportunity to build on a careful initial epidemiologic study over a long period of time, it can potentially yield substantial insight into the longitudinal trajectory of PTSD after disasters which has to date had little evaluation across periods longer than a decade.
