Introduction: Given the clinical and social relevance of psychopathy, it is desirable to have self-report instruments for a proper diagnostic approach. Objectives: Assess the internal congruence and convergent validity of the Self Report of Psychopathy Scale III-Short Form. Material and Methods: 208 convicts housed at the "Centro de Cumplimiento Penal" detention center in the Province of Los Andes, Chile, were evaluated using the SRP-III-SF, PCL-R, and HCR-20 schemes. Results: the SRP-III-SF distribution was normal, with a mean of 61.6. The Cronbach's Alpha Coefficient for the total was 0.8, and 0.7, 0.4, 0.7 and 0.5 for the 1, 2, 3, and 4 factors respectively, while the correlations of SRP-III-SF with PCL-R and HCR 20 were, respectively, 0.4 (p = 0.01) and 0.5 (p < 0,001). The scores of the PCL-R diagnosed psychopathy were linearly higher for each quartile of the SRP-SF distribution. The area under the ROC curve was 0.66 (p = 0.05; 95% IC 0.5; 0.8).
