Initial models and empirical investigations of rumination in the clinical literature were predominantly in the domain of depression. However, rumination is now well-established as a transdiagnostic cognitive process, in-cluding in the context of posttraumatic stress. To clarify the current understanding of rumination in posttraumatic stress, we conducted a systematic review of the empirical literature on rumination in posttraumatic stress disorder (PTSD). Six sub-groups of studies on this topic were identified; these addressed: (i) the frequency and nature of rumination, (ii) cross-sectional relationships between rumination and PTSD symptoms, (iii) the capacity of rumination to predict PTSD longitudinally, (iv) other processes associated with rumination, (v) neurobiological correlates of rumination, and (vi) whether treating PTSD reduces rumination. This review synthesizes these domains of research and identifies key methodological limitations which limit causal inferences, and points to important areas of future research to advance knowledge on rumination in PTSD.
