Moving beyond categories and dimensions in personality pathology assessment and diagnosis

It has been suggested that a dimensional model of personality pathology should be adopted for the development and refinement of personality disorder classification. In this article, the advantages and challenges of moving toward a dimensional model are briefly reviewed. However, it is suggested that although categories and dimensions are valuable frameworks for personality pathology diagnosis, an expansion beyond categories and dimensions is needed to improve the shortcoming seen in current diagnostic systems. Ideas and examples are offered for how this might occur.Declaration of interestNone.

Personality Disorders in the ICD-11: Opportunities and Challenges for Advancing the Diagnosis of Personality Pathology

PURPOSE OF REVIEW

The International Classification of Diseases-11th edition (ICD-11) is poised to make a dramatic change in the diagnosis of personality disorders by introducing a fully dimensionalized framework. In this paper, the history of this process is reviewed, along with international efforts taken to address some underlying concerns with this transition. Recent studies of this framework are also reviewed.

RECENT FINDINGS

Studies have concluded that the ICD-11 proposal is supported; however, there are a number of methodological limitations to these studies, including the utilization of measures that are not directly derived from the ICD-11 description of levels of personality severity and trait domains. There is a clear need for additional studies with measures that directly reflect the ICD-11 description of personality disorders. While there are some potentially positive effects of moving toward the dimensional model, there are a number of concerns remaining about the clinical utility of moving in this way.

Malignant Self-Regard in clinical outpatient samples

While the malignant self-regard construct and a corresponding questionnaire, the Malignant Self-Regard Questionnaire (MSRQ; Huprich, 2011) have been empirically evaluated in several non-clinical samples, it has yet to be evaluated in a clinical population. In this study, 139 outpatients in the Departments of Psychiatry and Behavioral Sciences (n = 83) and Internal Medicine (n = 57) were administered the MSRQ and a number other measures to assess its construct and incremental validity. The MSRQ was internally consistent in both samples, and was positively correlated with four dimensions of levels of personality functioning, DSM-5 personality trait domains, overdependence, detachment, insecure attachment, and general perceptions of physical and mental well-being. Furthermore, the MSRQ incrementally predicated variance in levels of personality functioning, interpersonal dependency, and general perceptions of physical and mental well-being above and beyond DSM-5 traits and (where appropriate) levels of personality functioning. These findings converge with studies of the MSRQ in nonclinical samples and support the clinical utility and validity of the MSRQ for further use.

Measures of Personality Pathology, Levels of Functioning, and Physical Health in an Urban Primary Care Sample

Integrative approaches in the primary care setting have grown in favor over the past few decades, with many interesting findings about the influence of personality disorders on physical health and functioning; however, less is known about how specific pathological personality traits impact patient-provider assessments of physical and mental health. Using the DSM-5 Levels of Personality Functioning Questionnaire-Short Form (DLOPFQ-SF) and Personality Inventory for DSM-5-Brief Form, these relationships were evaluated in a sample of 50 inner-city, low-income patients in a primary care clinic. Point-biserial correlations revealed significant correlations between physical and mental health morbidities, as well as personality pathology and patient response to treatment. Our findings lend further support to describing the relationships between personality pathology, medical comorbidities, and patient response to treatment.
