Survivors of critical illnesses are at increased risk for posttraumatic stress disorder and major depression. In the present issue of Critical Care, Myhren and colleagues report on an investigation of predictors of posttraumatic stress, general anxiety, and depressive symptoms up to 1 year following intensive care unit admission for critical illnesses. The present study found that an endogenous patient characteristic, the personality trait pessimism, was associated with posttraumatic stress and depressive symptoms. Myhren and colleagues' study sheds light on potential predictors of psychopathology in critical illness survivors as well as stimulating directions for future research to address these complex problems
