Resumo

LEON-MAYER, Elizabeth; FOLINO, Jorge O.; NEUMANN, Craig  e  HARE, Robert D.. The construct of psychopathy in a Chilean prison population. Rev. Bras. Psiquiatr. [online]. 2015, vol.37, n.3, pp.191-196.  Epub 01-Maio-2015. ISSN 1809-452X.  https://doi.org/10.1590/1516-4446-2014-1540.

Objective:

To test the four-factor model of the Hare Psychopathy Checklist - Revised (PCL-R) empirical construct of psychopathy in a Chilean prison population by using instruments that supply different types of data.

Methods:

Two hundred and nine male inmates of the Prison of Los Andes, Chile, were evaluated. Confirmatory factor analysis was carried out with the PCL-R and the Self-Report of Psychopathy - III - Short Form (SRP-III-SF).

Results:

The distributions of total PCL-R and SRP-III-SF scores were normal (Kolmorogov-Smirnov [K-S] = 1.04, p = 0.230; K-S = 0.812, p = 0.525, respectively), with means of 20.9±6.8 for the former and 61.6±15.2 for the latter. Model fit was good for the PCL-R (Tucker Lewis index [TLI] = 0.96; root mean square error of approximation [RMSEA] = 0.04) and for the SRP-SF (TLI = 0.94, RMSEA = 0.04).

Conclusions:

The results obtained with the PCL-R and the SRP-SF showed adequate fit to the empirical four-factor model of psychopathy and support this model. As foreseeable, fit was better for the PCL-R, which combines several sources of information.
