The present systematic review and meta-analysis sought to assess the internal structure and consistency of the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0) across different populations and cultures. Studies identified through systematic research were subjected to eligibility criteria, resulting in 30 included studies and 110 effect sizes. Study characteristics were tabulated, their methodological quality was assessed, and findings were synthesized using a random-effects meta-analysis. Findings overall supported the internal structure of the LPFS-BF 2.0 and indicated sound internal consistency for the total scale. Moderator analyses indicated that internal consistency differed minimally by index type, sample type, gender, age, country, and language. The findings overall suggest that the LPFS-BF 2.0 assesses a coherent and internally consistent construct, making it a potentially useful tool for evaluating personality functioning across diverse populations. Future investigations should further explore interrater reliability, test–retest stability, and alignment with interview-based personality disorder severity.

Abstract
The present systematic review and meta-analysis sought to assess the internal structure and consistency of the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0) across different populations and cultures. Studies identified through systematic research were subjected to eligibility criteria, resulting in 30 included studies and 110 effect sizes. Study characteristics were tabulated, their methodological quality was assessed, and findings were synthesized using a random-effects meta-analysis. Findings overall supported the internal structure of the LPFS-BF 2.0 and indicated sound internal consistency for the total scale. Moderator analyses indicated that internal consistency differed minimally by index type, sample type, gender, age, country, and language. The findings overall suggest that the LPFS-BF 2.0 assesses a coherent and internally consistent construct, making it a potentially useful tool for evaluating personality functioning across diverse populations. Future investigations should further explore interrater reliability, test–retest stability, and alignment with interview-based personality disorder severity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
