ABSTRACT

The study of psychopathy represents a key challenge, particularly in the field of clinical and forensic psychology. It is understood as a complex set of personality traits related to lack of empathy, interpersonal manipulation, and impulsive behavior. The Levenson Self-Report Psychopathy Scale (EAPL) (Levenson, et al., 1995) has been one of the most widely used measures to assess it; however, its psychometric properties have not been studied in the population of San Luis, Argentina. In order to investigate its reliability and validity, a two-stage descriptive-instrumental study was implemented, with samples of 279 and 261 participants, respectively. The first study showed that some items presented difficulties in exhaustively measuring the construct. Eliminated these, it was decided to evaluate a version of 20 components (EAPL-20). Exploratory factor analysis identified three factors, which explained more than 52% of the variance. The factor loadings clearly discriminated the corresponding factor and acceptable internal consistency indices were obtained, coinciding with previous studies carried out in various countries. In the second study, the confirmatory factorial analysis corroborated the agreement between the theoretical substrate in which the instrument is anchored and the proposed factorial structure, presenting itself as a valid alternative for use in our context.
