GARCIA VALENCIA, Jenny et al. Validation of the Psychopathy Check-List Revised (PCL-R) in Colombian Male Jail Inmates. rev.colomb.psiquiatr. [online]. 2008, vol.37, n.4, pp. 564-579. ISSN 0034-7450.
Introduction: Psychopathy is characterized by a pattern of constant affective deficit and lack of respect for other people's rights and social norms. The Psychopathy Check-List Revised (PCL-R) is an instrument of measurement composed of 20 items and it is one of the most used in psychopathy and antisocial personality disorder research. Objective: To validate the PCL-R in Colombian male inmates. Methods: Two translations into Spanish and two back-translations for each of the items were done. The instruction manual was also translated into Spanish and back-translated. Face validity was assessed by a group of experts. Content validity was examined as well as internal consistency, test-retest and inter-rater reproducibility. Results: In the factor analysis for the content validity, four domains were found which explained 61.1% of the variance. The internal consistency was high (Cronbach's Alpha=0.94). Similarly, the test-retest and inter-rater reproducibility were ICC=0.83, 95% CI: 0.68-0.91 and ICC=0.83, 95% CI: 0.86-0.96, respectively. Conclusions: The Spanish version of the PCL-R for Colombian male jail inmates shows good psychometric properties.
