RESUMO

MORANA, HCP. Identifying the Brazilian PCL-R (Psychopathy Checklist Revised) cut-off score for forensic population : characterizing two personality subtypes; global personality disorder (GPD) and Partial personality disorder (PPD). São Paulo, 2003. 178p. Tese (Doutorado) – Faculdade de Medicina, Universidade de São Paulo. In Brazil, there have been no standardized instruments in the legal and penal field so far that enable-identifying subjects who may relapse into crime, mainly those crimes of violent and cruel nature. The PCL-R, broadly used and institutionalized in several countries, fills such gap. The goal of the present study is to discriminate, through in-depth personality assessment, subjects considered psychopathic and non-psychopathic, correlated in this study to individuals specified as having global personality disorder (GPD) and partial personality disorder (PPD), respectively. The sample is composed of a random sample of 56 male subjects referred to as forensic population, these being: 33 subjects identified as GPD and 23 subjects identified as PPD. All 56 subjects have been assessed on the light of clinical data, judicial records, the Rorschach Test and the PCL-R. This population was compared to 30 subjects referred to as non-criminal population, and who have also been assessed via the same instruments as the sample. The personality of both forensic population groups fulfills ICD-10 criteria for antisocial personality disorder, but differences in terms of their psychic dynamics and personality determinants can be clearly identified, which impacts upon their social behavior in different ways. The accurate identification of such subjects presents multiple implications to the forensic and penitentiary system, and may contribute to reduce recidivism rates as well as violence levels in the country. Validation of the instrument (PCL-R) and identification of the cut-off score for the psychopathic condition (GPD in our notation), for the sample drawn from the Brazilian forensic population has been conducted through the concurrent analysis of both instruments of assessment, resulting in a 23 cut-off score (CI = 21.61 to 24,05). The average value is 28,63 (CI= 26,78 to 30, 48). Sensitivity outcome is 84,8%. Specificity is 100%. The reliability rates found for both instruments were high (Kappa = 0.8735).
