Key Points
Question What is the association of mortality with baseline and repeated assessments of posttraumatic stress disorder in a population exposed to the World Trade Center attacks on September 11, 2001, over 13 years of follow-up?
Findings In this cohort study of 63 666 World Trade Center Health Registry enrollees, posttraumatic stress disorder was associated with an increased risk of mortality and associations were strengthened when considering posttraumatic stress disorder status over time compared with a single posttraumatic stress disorder assessment at study entry.
Meaning Without considering the time-varying outcomes of posttraumatic stress disorder, important differences in the association of posttraumatic stress disorder and mortality may be masked.
