摘要

This meta-analysis investigates the relationship between alexithymia and aggression by synthesizing data from 59 studies (60 samples; N = 30,046). A comprehensive search was conducted across five databases—PubMed, PsycINFO, Web of Science, ProQuest, and CNKI—and Google Scholar using terms related to “aggression” and “alexithymia.” Inclusion targeted studies reporting alexithymia–aggression associations in general or clinical/diagnosed samples where these constructs were a primary focus, while excluding studies of severe violent offender/forensic samples or those centered on other primary psychiatric conditions. The results indicate a significant, positive correlation between alexithymia and aggression (ρ = 0.327, 95% CI [0.287, 0.365]). Moderation analyses showed that effect sizes varied by aggression subtypes, alexithymia facets, and the instrument used to assess aggression. These findings advance the understanding of the alexithymia–aggression link and may inform future research and clinical interventions aimed at mitigating aggression associated with alexithymia.
