Trajectories of posttraumatic stress symptoms after whiplash: A prospective cohort study

Posttraumatic stress disorder (PTSD) symptoms are highly prevalent after whiplash and associated with pain‐related symptoms. While mutual maintenance between pain and PTSD has been suggested, knowledge on individual differences in the course of these symptoms is needed. The present study aimed to identify trajectories of PTSD symptoms following whiplash and test predictors and functional outcomes of such trajectories.
