Abstract

The American Psychiatric Association supported the development of several instruments to assess personality pathology according to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM–5) Section III. These instruments include self- and informant report forms as well as clinician-rated measures of personality traits and impairment. To date, the psychometric properties of the DSM–5 Section III clinician-rated measures have received limited investigation. The objective of the current investigation was to evaluate the convergence between self-report and clinician-rated measures of DSM–5 personality pathology in a diagnostically heterogeneous psychiatric patient sample. A total of 201 outpatients with current psychiatric symptoms were recruited from a psychiatric hospital patient research registry. Participants completed both clinician-rated and self-reported measures of personality pathology. Self-reported personality traits converged with clinician-rated personality traits, with medium to large effect sizes. Current and Section III personality disorder criteria demonstrated significant convergence, most with medium to large effect sizes. Self-reported and clinician-rated personality impairment correlated with small to medium effect sizes. The current investigation incorporates a multi-informant assessment of personality in a psychiatric outpatient sample. These results provide evidence for the validity of the scores of the clinician-rated instruments used to implement this model. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
