This meta-analysis examined the associations between adverse childhood events (ACEs) and cluster C personality disorders. The results showed consistent associations between ACEs and all cluster C personality disorders. The associations weakened with age.
Introduction: Studies suggest that adverse childhood events (ACEs) may contribute to the onset and development of cluster C personality disorders. However, the association between ACEs and these disorders remains unclear in terms of consistency across studies and effect magnitude, as well as generalizability within cluster C. The current meta-analysis aimed to examine the associations between ACEs and cluster C personality disorders based on the available literature. Methods: Systematic searches were conducted in PubMed, Scopus, Web of Science and PsychInfo. Forty-eight eligible studies were included in the analyses, and pooled effect sizes were estimated both at the level of cluster C and at the level of each specific disorder. Moderation and meta-regression analyses were also conducted. Results: ACEs were consistently associated with overall cluster C, as well as each of the specific disorders in this cluster. Sources of heterogeneity included type of instrument used to assess ACEs (questionnaires > interviews) and type of instrument used to assess the personality disorders (clinical interviews > questionnaires, as well as their combination with interview). The associations between ACEs and all cluster C personality disorders decreased with age. Conclusions: ACEs are consistently associated with all cluster C personality disorders. Future work could approach the mechanisms underlying this association, preferably using longitudinal designs and considering the potential sources of effect variability identified in the present study.
