PG - 247-260 LID - 145912 [pii] LID - 10.12740/PP/OnlineFirst/145912 [doi] AB - OBJECTIVES: This study examined psychometric properties of the Polish adaptation of the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0) measuring features corresponding to self - and interpersonal impairment of personality functioning as defined in the diagnostic guidelines for Personality Disorder in the DSM-5 Section III. METHODS: The study involved a non-clinical sample of N = 242 adults (52.9% female; Mage = 30.63 years, SDage = 11.81 years). To evaluate the criterion validity, the Personality Inventory for DSM-5 (PID-5), Personality Inventory for ICD-11 (PiCD), Agency-Communion-Inventory (AC-IN), and Mental Health Continuum-Short Form (MHC-SF) were administered. RESULTS: The LPFS-BF 2.0 yielded two reliable latent components that correspond to an interpretation of self - and interpersonal functioning and showed relevant associations with a personality disorder severity index, maladaptive personality traits, well-being, and personality constructs of agency and communion. The LPFS-BF 2.0 also demonstrated incremental validity over and above all the PID-5 pathological traits with respect to global well-being as an outcome. CONCLUSIONS: The Polish adaptation of the LPFS-BF 2.0 is a psychometrically and conceptually sound measure to assess features corresponding to self and interpersonal impairment of personality functioning as defined in the DSM-5 Section III. However, findings warrant replication in clinical populations. FAU - Lakuta, Patryk AU - Lakuta P AD - Uniwersytet Kardynala Stefana Wyszynskiego w Warszawie, Instytut Psychologii.
