| Abstract Text | Objectives: This study examined psychometric properties of the Polish adaptation of a Self-Report Form of the DSM-5 Level of Personality Functioning Scale (LPFS-SR). It is a scale designed to measure general impairment, jointly with a detailed assessment of distinguished components of personality functioning characterized in terms of disturbances in self (identity and self-direction) and interpersonal (empathy and intimacy) functioning – Criterion A in the DSM-5 Alternative Model for Personality Disorders (AMPD). Methods: The study involved a non-clinical sample of N = 242 adults (52.9% female; Mage = 30.63 years, SDage = 11.81 years). To provide an evaluation of the criterion validity, Personality Inventory for DSM-5 (PID-5), Personality Inventory for ICD-11 (PiCD), Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0), and Big Five Inventory-2 (BFI-2) were administered. Results: Our data supported that identity, self-direction, intimacy, and empathy components of the LPFS-SR can be characterized by a single, global dimension of personality dysfunction, consistent with the assumption that DSM-5 Criterion A is a relatively homogeneous construct. The LPFS-SR showed good reliability estimates and demonstrated conceptually sound associations with the PD severity index and related measures of personality functioning. Moreover, all the LPFS-SR components manifested at least partial distinction from maladaptive personality traits (i.e., Criterion B in the DSM-5 AMPD). Conclusions: These findings provide support for the validity of the Polish adaptation of the LPFS-SR as an operationalization of impairment in the core and common features of personality pathology described in the DSM-5 alternative model. |
