Factor structure of the Self-Report Psychopathy scale (SRP-II) in non-forensic samples

The construct of psychopathy in a Chilean prison population

“…Much of the validation research for these self-reported instruments has been carried out with clinical or forensic samples. In 1991, Hare 18 reported a correlation of 0.54 between the SRP-II and the PCL-R in a sample of 100 inmates; Williams & Paulhus 31 reported similar correlations with other self-report inventories (0.56). These same authors report that the SRP-II has proven its power to discriminate subclinical psychopaths, also called successful psychopaths by Cleckley, 2 as well as other personality disorders such as narcissistic personality disorder and/or machiavellism.…”

“…30 Nevertheless, relatively few research studies have used the PCL scales in the general community, 31 in part due to the difficulty involved in application of the instrument, including the interview and collection of the additional information required, the lack of community norms, and the training required for its use. Thus, in 1985, considering the potential advantages of self-report inventories, Robert Hare created the SRPS.…”

“…32 According to Williams & Paulhus, the theoretical nearness of the SRPS and the PCL-R is an advantage over all other self-reported inventories in psychopathy. 31 Subsequently, Hare created a group of 60 items that gave birth to the SRP-II, followed by the SRP-III and, finally, the SRP-III-SF, 13 which is used in this study. Much of the validation research for these self-reported instruments has been carried out with clinical or forensic samples.…”

“…These same authors report that the SRP-II has proven its power to discriminate subclinical psychopaths, also called successful psychopaths by Cleckley, 2 as well as other personality disorders such as narcissistic personality disorder and/or machiavellism. 31 The SRP-III-SF comprises 29 items that are distributed across four factors derived from the PCL-R. Factor 1 of the SRP-SF is compatible with the indicators of interpersonal functioning and it is formed by items 7, 9, 10, 15,…”

“…A previous study of the SRP-SF showed good convergence with the PCL-R, although individuals tend to present themselves in a more favorable way regarding those obtained with other instruments, which is not surprising for self-report questionnaires. 31 This study is part of a more comprehensive project that had the approval of the Faculty of Medical Sciences of Universidad Nacional de La Plata and of the Penitentiary Figure 1 Psychopathy Checklist -Revised (PCL-R) four-factor model confirmatory factor analysis (n=206). Tucker index = 0.96; root mean square error of approximation = 0.04.…”
