LEON-MAYER, Elizabeth; ASUN-SALAZAR, Domingo y FOLINO, Jorge óscar. Chilean version of Hare PCL-R: a study of reliability and validity. Rev.fac.med.unal [online]. 2010, vol.58, n.2, pp. 103-114. ISSN 0120-0011.
Background. In Chile as in other Latin American countries the introduction of the Adversarial Model in the Judicial System increased the need for the systematization of the evaluation of psychopathy, thus making necessary the translation, adaptation and revision of the psychometric properties of the Hare Psychopathy Checklist Revised. Objective. To evaluate aspects of the reliability and validity of the Chilean version of the PCL-R in Chilean male inmate population. Materials and methods. The PCL-R was translated and backtranslated with the authorization of the author and of the Editorial House. A sample of 293 inmates was constituted and the respective informed consent obtained. Several analyses were made including a blind comparison of the diagnosis made with the PCL-R and the one made by the Technical Area of Gendarmería of Chile. Results. The internal congruence measured with Crombach Alfa was: total =0,91; F1= 0,86; F2 = 0,87; F3 = 0,67; F4= 0,77. Kappa value for both types of evaluations = 0,804; p < 0,001. Statistically significant association between psychopathy and condition of reoffending (OR = 12,8; 95 % IC = 5; 33). Confirmatory factor analysis supports the four factor model of psychopathy. Conclusion. The findings support the validity of the Chilean version of the PCL-R and the factor analysis confirmed, for the Chilean sample, the four factors solution of the construct of psychopathy measured by the PCL-R.
