the relationship between the structures of personality inventory for the diagnostic and statistical manual, fifth edition (pid-5) and minnesota multiphasic personality inventory-2-restructured form (mmpi-2-rf)

Objective: the personality inventory for the diagnostic and statistical manual of mental disorders, fifth edition (pid-5), is a trait-based measure of pathological personality designed to assess criterion b of an alternative diagnostic system for personality disorders (pds). in this study, we aimed to evaluate the relations among the pid-5 and the minnesota multiphasic personality inventory-2-restructured form (mmpi-2-rf); a commonly used self-report instrument with a hierarchical structure.method: we examined the joint structure of the pid-5 scales along with levels of the mmpi-2-rf hierarchy to understand whether conceptually expected structures tend to be loaded with each other. data were collected from 536 participants from the general population of iran.results: findings of pearson’s correlation analyses exhibited the generally expected patterns between the two mentioned measures on most scales, with some divergences. similarly, although applying a set of joint exploratory structural equation modeling (esem) exhibited some factor loadings for pid-5 facets within the hierarchical framework of mmpi-2-rf scales that were different to what was theoretically expected, both measures were generally loaded in a conceptually expected way, indicating that they have a similar dimensional structure.conclusion: our findings provide support for adequate convergence of maladaptive personality traits and psychopathology structures, as well as for utilizing mmpi-2-rf to measure personality psychopathology from a dimensional perspective. the implications of these results are discussed by the authors.
