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.

Convergent and Discriminant Validity of Self-Report and Performance-Based Assessment of Object Relations.

This study evaluated the Social Cognition and Object Relations Global Rating Method (SCORS-G; Stein, Hilsenroth, Mulford, & Pinkser, 2011; Stein and Mulford, 2018; Westen, 1995) and the Bell Object Relation and Reality Testing Inventory (BORRTI; Bell, 1995) to determine the extent to which the measures were correlated with each other and their relationships with 2 disorders characterized by disrupted object relations: borderline personality disorder (BPD) and depressive personality disorder (DPD). One hundred sixty-nine psychiatric outpatients and 171 undergraduate students were assessed with the Personality Disorder Interview for DSM-IV (Widiger, Corbett, Ellis, Mangine, & Tomas, 1995) and the Structured Clinical Interview for DSM-IV Axis II Disorders (First et al., 1997) for BPD and DPD. Modest correlations were observed among the diagnostic interviews with the BORRTI and the SCORS-G. An exploratory factor analysis yielded 3 distinct factors, 1 of which was mainly comprised of the BORRTI scales, whereas the 2 other factors were comprised of SCORS-G dimensions. Hierarchical multiple regressions demonstrated that the BORRTI accounted for greater variance among interview scores for both groups. However, the addition of SCORS-G variables incremented the variance accounted for in the BORRTI.

Understanding the relationship between personality pathology and attachment style in the context of the DSM-5 Alternative Model of Personality Disorders.

This study utilizes the two different criteria of the DSM-5 Alternative Model of Personality Disorder Assessment to evaluate the relationship between attachment style and personality pathology. One-hundred forty patients from a combined sample of psychiatric and internal medicine clinics were given a survey composed of the DSM-5 Levels of Personality Functioning Questionnaire (DLOPFQ), the Personality Inventory for DSM-5-Brief Form (PID-5-BF), and the Relationship Questionnaire (RQ). Analysis of variance indicated that attachment styles were differentiated across all four the DLOPFQ scales and the Detachment trait domain. Elastic net regression modeling with bootstrap was used to assess the strength of the level of personality functioning dimensions and trait domains in the prediction of attachment style, both independently and interactively while accounting for multicollinearity. This study offers readers insight to a novel statistical approach to model building that addresses two issues among psychiatric data: high correlation and small sample size.
