Abstract

Abstract: Trauma can disrupt an individual's core beliefs about themselves, others, and the world. Posttraumatic growth (PTG) is thought to be the outcome of a reconstruction process involving ruminative processing. This meta‐analysis examined the strength of the associations between event‐related intrusive and deliberate rumination and PTG. The moderating effects of variables including age, time since trauma exposure, and trauma type were examined. Eight databases were searched for English‐language, peer reviewed studies examining the associations between PTG and types of event‐related rumination in adults. Effect sizes (Pearson's r ) were extracted and analyzed, and study quality was assessed using the Study Quality Assessment Tool for Observational and Cohort studies. In total, 46 studies were included based on the inclusion and exclusion criteria. A significant main effect was observed for the association between retrospectively reported deliberate rumination that occurred soon after a traumatic event and PTG, r = .45, 95% CI [.41, .49]. There was significant variability in effect sizes, and the strength of this association differed according to age. The association between intrusive rumination and PTG was not significant and varied in direction. Deliberate rumination that occurred relatively soon following trauma exposure was shown to be positively associated with PTG. The findings highlight the importance of supporting trauma survivors to engage in the deliberate cognitive processing of their experiences to encourage PTG. Longitudinal research is needed to further delineate the temporal role of event‐related rumination in PTG development.
