9-11 Research: What is the Risk of WTC Responders Developing PTSD as a Result of 9/11 Exposures?

The objectives of the World Trade Center (WTC) Trajectories study are to (1) characterize longitudinal trajectories of WTC-related posttraumatic stress disorder (PTSD) in WTC responders; (2) examine specific risk and protective determinants of these trajectories; and (3) identify personal and psychosocial factors associated with resilience and recovery trajectories, with the ultimate goal of maximizing preparedness and improving mental health outcomes in disaster responders.
