TLDR
A maladaptive personality trait model and corresponding instrument are developed as a step on the path toward helping users of DSM-5 assess traits that may or may not constitute a formal personality disorder.Abstract:
Background DSM-IV-TR suggests that clinicians should assess clinically relevant personality traits that do not necessarily constitute a formal personality disorder (PD), and should note these traits on Axis II, but DSM-IV-TR does not provide a trait model to guide the clinician. Our goal was to provide a provisional trait model and a preliminary corresponding assessment instrument, in our roles as members of the DSM-5 Personality and Personality Disorders Workgroup and workgroup advisors. Method An initial list of specific traits and domains (broader groups of traits) was derived from DSM-5 literature reviews and workgroup deliberations, with a focus on capturing maladaptive personality characteristics deemed clinically salient, including those related to the criteria for DSM-IV-TR PDs. The model and instrument were then developed iteratively using data from community samples of treatment-seeking participants. The analytic approach relied on tools of modern psychometrics (e.g. item response theory models). Results A total of 25 reliably measured core elements of personality description emerged that, together, delineate five broad domains of maladaptive personality variation: negative affect, detachment, antagonism, disinhibition, and psychoticism. Conclusions We developed a maladaptive personality trait model and corresponding instrument as a step on the path toward helping users of DSM-5 assess traits that may or may not constitute a formal PD. The inventory we developed is reprinted in its entirety in the Supplementary online material, with the goal of encouraging additional refinement and development by other investigators prior to the finalization of DSM-5. Continuing discussion should focus on various options for integrating personality traits into DSM-5.read more

Personality traits as an organizing framework for personality pathology.

TL;DR: The findings highlight the strong overlap between normal and pathological personality and clarify the nature of the associations between them, demonstrating substantial links between four of the five domains within these models.

Links between depression and openness and its facets

TL;DR: Although the Openness domain was significantly related to depression, it did not account for a significant proportion of unique variance for depression at the facet level, and unique effects emerged for the facets of Aesthetics positively predicting depression and Values negatively predicting Depression and Anhedonia.

TL;DR: In this article, the authors examined age-neutrality of the Short Form of the Severity Indices of Personality Problems (SIPP-SF; Criterion A) and Personality Inventory for DSM-5-Brief Form (PID-5BF); Criterion B) in a community sample of older and younger adults.

TL;DR: Sex measurement invariance of the DSM–5 Section III pathological personality trait model is fully structurally equivalent across sex, a property that is lacking in the traditional categorical model in Section II.

Comparing the validity of trait estimates from the multidimensional forced-choice format and the rating scale format.
Eunike Wetzel,Susanne Frick +1 more
TL;DR: The reliability of trait estimates on the Big Five and test-retest reliabilities were lower for MFC compared to RS, and more research on how to obtain ideal constellations of items that are matched in their desirability is needed.

Estimating the Dimension of a Model
TL;DR: In this paper, the problem of selecting one of a number of models of different dimensions is treated by finding its Bayes solution, and evaluating the leading terms of its asymptotic expansion.

TL;DR: The first large-scale testing of PROMIS item banks and their short forms provide evidence that they are reliable and precise measures of generic symptoms and functional reports comparable to legacy instruments.
