Exploring personality correlates of psychiatric hospitalization: A cross-sectional comparison of section ii personality disorder model and alternative model for personality disorders.

ABSTRACT

Our cross-sectional study provides a head-to-head comparison of Section II and Section III of Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic models of personality disorders (PDs) in identifying significant personality correlates of psychiatric hospitalization (PH). PH is an indicator of a breakdown in one's existing ability to manage mental crisis. The sample was recruited from psychiatric clinical services (N = 60) as well as universities and the local community (N = 49). We used the Structured Clinical Interview for DSM-5 PD (SCID-5-PD) for Section II DSM-5 diagnosis, the Self and Interpersonal Functioning Scale (SIFS) for Criterion A and the Personality Inventory for DSM-5 (PID-5) for Criterion B. Separate logistic regressions analyses showed high discriminative utility for all diagnostic models the number of Section II diagnosis, level of personality functioning, and five maladaptive traits (AUC between .89 and .97). Binomial logistic regression with a forward stepwise procedure showed that Section II number of diagnoses revealed incremental utility over Criteria A and B in distinguishing between individuals experiencing a mental health crisis requiring PH and those not requiring immediate intervention. We conclude that each diagnostic model, when considered individually, exhibits a high degree of discriminatory performance. However, employing all these models concurrently for identifying personality correlates of PH proves impractical. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
