The 2-year test-retest reliability of the psychopathy checklist-revised inmethadone patients

The 2-year test-retest reliability of the Psychopathy Checklist-Revised (PC LR) was examined in 200 men and 25 women methadone patients. Stability of t he PCL-R was generally good whether it was evaluated as a dichotomous or di mensional measure. Utilizing a diagnostic cutoff score of 25 or more the in traclass correlation coefficients (ICCs) were .48 for men and .67 for women . For the Total PCLR score ICCs were .60 and .65 for men and women, respect ively. Factor 1 was more reliably measured in women compared to men (.63 vs . .43). For men, Factor 1 was significantly less reliable than Factor 2 or the Total score. For women, Factor 2 was significantly less reliable than t he Total PCLR score or Factor 1.
