Psychopathy is a construct characterized by affective, interpersonal, and behavioural traits (Morrissey et al., 2010) associated to irresponsible and impulsive behaviour, contempt for and violation of social norms (Flores-Mendoza, Silva-Alvarenga, Herrero, & Abad, 2008), deep affective deficits, and a lack of respect for the rights of others (García et al., 2008 Hare, 1996, 2003 Torrubia, Poy, Moltó, Grayston, & Corral, 2010 Vien & Beech, 2006). The results are discussed in terms of their implications for theoretical models of psychopathy, decision-making, prison classification and intervention, and prevention. The scale resulting from the three-factor hierarchical model with testlets (13 items) classified psychopathy significantly higher than the original 20-item scale. 86), and the three-factor model with testlets was a reasonable fit for the data (CFI =. The results revealed that the two-factor correlational, three-factor hierarchical without testlets, four-factor correlational and hierarchical, and unidimensional models were a poor fit for the data (CFI ≤. Two trained and experienced independent raters scored 197 prisoners from the Villabona Penitentiary (Asturias, Spain), age range 21 to 73 years ( M = 36.0, SD = 9.7), of whom 60.12% were reoffenders and 73% had committed violent crimes. The aim of this study was to determine which of the factorial solutions proposed for the Hare Psychopathy Checklist-Revised (PCL-R) of two, three, four factors, and unidimensional fitted best the data. Se discuten las implicaciones de los resultados para los modelos teóricos de la psicopatía, la toma de decisiones, clasificación e intervención penitenciaria, y la prevención. La escala resultante del modelo de tres factores con testlets (13 ítems) mostró un poder de clasificación de la psicopatía significativamente superior al de la escala original (20 ítems). 86) y un ajuste razonable del modelo jerárquico de tres factores con testlets (CFI =. Los resultados mostraron que los modelos unidimensional, correlacional de 2 factores, jerárquico de 3 factores sin testlest y correlacional y jerárquico de 4 factores, presentaban un pobre ajuste con los datos (CFI ≤.
Para ello, dos evaluadores entrenados y con experiencia evaluaron de forma independiente a 197 internos en la prisión Villabona (Asturias, España), con edades comprendidas entre los 21 y los 73 años ( M = 36.0, DT = 9.7), de los cuales el 60.12% eran reincidentes y el 73% había cometido delitos violentos. Se diseñó un estudio con el objetivo de conocer cuál de las soluciones factoriales propuestas para la Hare Psychopathy Checklist-Revised (PCL-R) de dos, tres y cuatro factores y unidimensional era la que presentaba mejor ajuste a los datos.
