Abstract

The aim of this study was to explore the psychometric proprieties of the Lies and Inconsistencies Restructured Battery (BMI -RT). The sample was made using a non-probabilistic sampling and it was composed of 553 subjects. The construct validity examination applying the Principal Component Analysis with quartimax rotation showed an internal structure formed by 4 factors: Magical Beliefs (Cs); Lies (L); Extravagant Behaviors (Ce); and Inconsistencies (K). The reliability analysis employing Cronbach’s Alpha offered a significant internal consistency (Alpha≥ .9). The final results confirmed that 31-item BMI -RT is a valid and reliable instrument, following the theoretical parameters about declarative validity in the scientific context.
