Sessions Abstract: The Alternative Model for Personality Disorders (AMPD; APA, 2013) Criterion A describes the severity of personality impairment, meant to represent what all personality disorders share in common. Recently there have been several new measures developed to capture this core of personality dysfunction. This symposium brings together several lines of research examining existing measures of Criterion A and new ways to measure Criterion A. Abby Mulay and colleagues examined relationships between the newly developed spectra scales of Mulay et al. (2019) and Sellbom et al. (2018) from the family of MMPI instruments and the Severity Indices of Personality Problems (SIPP-118). Using these comparisons as a starting point, this study explores the development of a scale to assess Criterion A of the AMPD. Melanie Glatz and John Kurtz examine the LPFS-SR, and present findings in support of greater discriminant validity of the four element scores using relevant measures from the social-personality research literature. Chloe Bliton and colleagues examined the structure and criterion validity of three Criterion A self-report measures. Michael Roche investigated the criterion validity of Criterion A measures in relation to mental health utilization and psychopathology dimensions in a college sample. Finally, Nicholas Jacobson and Iain Sheerin applied deep learning models to predict the level of observer rated and self-reported level of personality functioning (Criterion A) based on undergraduate participant's life story narratives. They discuss the predictive accuracy of these models to this application as well as the most important characteristics which influence model predictions. These talks highlight the advancements in conceptualization and assessment of Criterion A in the AMPD.

Presentation 3 Title: Examining the Structure and Validity of Criterion A Self-Report Measures

Presentation Abstract: The Level of Personality Functioning Scale (LPFS) operationalizes Criterion A of the DSM–5 Alternative Model for Personality Disorders and was designed to capture personality pathology dysfunction. Despite progression in LPFS measurement development and validation, there is a lack of research, and some disagreement, concerning structural, convergent, and incremental validity of LPFS self-report measures. The present study aimed to compare the LPFS – Self-Report, DSM-5 LPFS, and LPFS – Brief Form. Internal structure was assessed through principal component analyses, factor analyses, and bifactor analyses of unidimensionality. Associations with both pathological and normal personality characteristics among the LPFS measures were explored. Incremental validity of LFPS severity in predicting pathological personality outcomes controlling for normal personality traits was examined. Results suggest unidimensional structure robustly associated with other pathological personality assessments. LPFS severity and normal personality traits mutually offered unique explanatory power. We discuss the implications of assessing personality pathology using LPFS self-report measures.
