Abstract
The present study investigated the predictive validity of Criterion A and B of the Alternative Model for Personality Disorders (AMPD) compared to the DSM-5 Section II personality disorder (PD) model in predicting patient outcomes 1 year after initial assessment, in a hetero-method longitudinal design. A clinical sample of 84 participants were administered both traditional Section II and AMPD interviews by two independent interviewers. One year after assessment, disability (World Health Organization Disability Assessment Schedule 2.0) and symptom severity (Brief Symptom Inventory) were assessed. The Section II PD model did not predict disability ( R² = .01) nor symptom severity ( R² = .03). The AMPD model, on the other hand, predicted both disability ( R² = .23) and symptom severity ( R² = .29) 1-year postinitial assessment. Both Criterion A and B were significant predictors, but when jointly combined only Criterion A remained significantly predictive of both disability and symptom severity while Criterion B did not. Criterion A thus appears to capture core vulnerabilities of personality-disordered patients that are related to future functioning and symptom severity. Implications for clinical practice are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
