Investigating Convergence of the ICD‐11 Personality Disorder Model and the DSM‐5's Alternative Model of Personality Disorders

ABSTRACT

The introduction of the DSM‐5's AMPD and the ICD‐11 PD model are demonstrative of a shift in personality disorder classification from the more traditional categorical taxonomy to dimensional diagnostic approaches. The two models possess a number of similarities, however, are also substantially different in terms of the AMPD's hybrid nature and facet structure, in addition to disparity between the anankastia and psychoticism trait domains. This narrative review attempted to ascertain whether there is convergence between the two models, in addition to improving upon previous meta‐analytical work done on the subject, by synthesizing the findings from 32 studies and examining their findings as well as their methodological quality. Similar to previous work, correlational findings from studies within the review seemed to suggest potential convergence between the two models. However, potential alternate explanations for the moderate‐to‐large effect size correlations are given. Additionally, this review's expanded look at methodological factors and other types of analyses revealed evidence which does not support convergence. Overall, the findings of the studies in this review hamper the ability to conclude that there is in fact convergence between the two models. The results of this review provide pertinent clinical and research implications, in addition to producing avenues for further research aimed at improved investigation of convergence between the AMPD and ICD‐11 PD model.
