Abstract

Posttraumatic stress disorder (PTSD) is a complex condition with affective components that extend beyond fear and anxiety. The emotion of shame has long been considered critical in the relation between trauma exposure and PTSD symptoms. Yet, to date, no meta-analytic synthesis of the empirical association between shame and PTSD has been conducted. To address this gap, the current study summarized the magnitude of the association between shame and PTSD symptoms after trauma exposure. A systematic literature search yielded 624 publications, which were screened for inclusion criteria (individuals exposed to a Criterion A trauma, and PTSD and shame assessed using validated measures of each construct). In total, 25 studies employing 3,663 participants met full eligibility criteria. A random-effects meta-analysis revealed a significant moderate association between shame and posttraumatic stress symptoms, r =.49, 95% CI [0.43, 0.55], p <.001. Moderator analyses were not completed due to the absence of between-study heterogeneity. Publication bias analyses revealed minimal bias, determined by small attenuation after the superimposition of weight functions. The results underscore that across a diverse set of populations, shame is characteristic for many individuals with PTSD and that it warrants a central role in understanding the affective structure of PTSD. Highlighting shame as an important clinical target may help improve the efficacy of established treatments. Future research examining shame's interaction with other negative emotions and PTSD symptomology is recommended.
