The Reliability and Validity of the Turkish Version of Psychopathy Checklist-Revised (Turkish PCL-R)

Abstract

Objectives: Psychopathy is a distinct personality organization and differs from antisocial personality disorders in many aspects. Its diagnosis is challenging but also critical to predict criminality. In this context, Psychopathy Checklist Revised (PCL-R) is a useful tool in the diagnosis of psychopathy. Its reliability and validity was shown in various populations but has not been studied in a Turkish population. Our aim was to demonstrate the reliability and validity of PCL-R in a sample from Turkey. Methods: 425 male subjects with antisocial personality disorder and 125 controls without any psychiatric diagnoses were included in the study. DSM-5 diagnostic criteria were used and PCL-R was administered to all participants. The reliability of the Turkish version of PCL-R was determined by test-retest and internal consistency methods. In the ROC analysis performed with PCL-R, DSM-5 criteria were taken as a gold standard, the sensitivity; specificity and cutoff values of PCL-R were estimated. To evaluate the adequacy of the scale construct validity, Exploratory Factor Analysis and Kaiser-Meyer-Olkin (KMO) and Barlett tests were applied. Reproducibility of the test was evaluated by Pearson correlation coefficient. Re-testing was performed with 171 subjects two weeks after the first test. Results: In reliability analysis, the Cronbach's alpha internal consistency coefficient was calculated to be α=0.977. Pearson correlation coefficient of test-retest was r=0.94 (p<.001). Item-total correlations ranged from 0.18 to 0.94. Its sensitivity and specificity was 98.3% and 100.0%, respectively, with a cutoff point of 20. In principal component analysis, two factors had Eigen values greater than 1. These two factors accounted for 76.54% of the variance in PCL-R scores. Conclusions: Turkish PCL-R is a valid and reliable measure of psychopathy to detect psychopathic traits. However, more studies on psychopathy need to be conducted in different Turkish sample groups.

Validation of the Levenson Self-Report Psychopathy Scale in Bulgarian Substance-Dependent Individuals

“…To our knowledge, there are no studies on the psychometric properties of the LSRP in Eastern Europe. However, the PCL-R has proven to be a reliable tool for measuring psychopathy in Turkey (Tutuncu et al, 2015), and the PCL:SV has been successfully validated in Lithuania (Žukauskienė et al, 2010) and Bulgaria (Wilson et al, 2014).…”

Psychopathy, temperament, and character dimensions of personality as risk determinants of criminal recidivism in schizophrenia patients

“…Hare and other authors have argued that it is appropriate to evaluate the psychopathy level via the PCL‐R dimensionally without a cut‐off score [46]. Validity and reliability of the Turkish version of the PCL‐R were reported by Tutuncu et al in an ASPD sample in which Cronbach's alpha internal consistency coefficient was calculated to be 0.977 [47]. In this study, we used the Turkish version of PCL‐R with permission from Ger and Oncu who translated and obtained the copyright permission from the developer of the scale. The Temperament and Character Inventory ‐ Revised ( TCI ‐ R ): The TCI was developed by Cloninger on the basis of psychobiological personality theory and is a self‐report scale consisting of 240 items [30].…”
