Abstract
Over the last years, data on the relationship between rumination and executive functions has been mixed. This meta-analysis aimes to provide an estimate of the overall and specific effect sizes of the relationship between rumination and executive functions (EFs): working memory, shifting and inhibition, and to test possible moderators of these associations. From a total number of 1123 considered abstracts, 64 articles (70 studies) met our inclusion criteria. The r coefficient for every outcome measure was calculated. The overall effect size revealed no relationship between rumination and EFs (r = 0.09, p = 0.001). Also, there was no relationship between rumination and working memory (r = 0.06, p = 0.12). However, we found small effect sizes for the association between rumination and shifting (r = 0.17, p = 0.001) and between rumination and inhibition (r = 0.11, p = 0.012). The only significant moderators were type of sample and sample size, which moderated the rumination – inhibition relation. These findings suggest that rumination may be associated with some EFs (i.e. inhibition, shifting) but the magnitude of this association is relatively small. Theoretical and practical implications are discussed.
