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

Reliability and Validity of the Personality Inventory for DSM-5 (PID-5): Predicting DSM-IV Personality Disorders and Psychopathy in Community-Dwelling Italian Adults
TL;DR: The hypothesis that the PID-5 is a reliable instrument which is able to recover DSM- IV PDs, as well as to capture personality pathology that is not included in the DSM-IV (namely, psychopathy) is supported.

TL;DR: Examination of associations between the MMPI-2-RF PSY-5 scales and the DSM-5 trait domains and facets indexed by the PID-5 shows clear evidence that the M MPI- 2-RF has utility in the assessment of dimensional personality traits proposed for the upcoming DSM- 5.

TL;DR: Support for the psychometric properties of this diagnostic instrument in psychiatric samples is provided and the internal consistencies of the PID-5 domain and facet trait scales were acceptable.

Personality, Emotions, and the Emotional Disorders
TL;DR: Neuroticism correlated strongly with the symptoms of general distress/negative affectivity that are central to these disorders; more moderately with symptoms of social phobia; and more modestly with agoraphobia, specific phobia, and other symptoms of depression and obsessive-compulsive disorder.

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.
