Brazilian Version of the Level of Personality Functioning Scale-Brief Form 2.0: Evidence of Reliability and Validity.

The goal of this research was to investigate the psychometric properties of the Level of Personality Functioning Scale - Brief Form - 2.0 (LPFS-BF-2.0) in Brazilian samples. Therefore, two samples were used in this study, one with 415 and the other with 1,011 Brazilians. Participants completed the Brazilian version of the LPFS-BF-2.0 and other measures of common mental disorder symptoms, suicide risk, the severity of personality pathology, and pathological personality traits. The results indicated that the two-factor model (including self-functioning and interpersonal functioning domains) fits the Brazilian samples better than a one-factor model. The LPFS-BF-2.0 scales indicated adequate reliability coefficients and evidence of convergent validity. [ABSTRACT FROM AUTHOR]
