Psychopathy Assessment with PCL-R has High Interrater Reliability if Conducted Without Bias
2016 (English)Conference paper, Presentation (Other academic)
Scores of the Psychopathy Checklist-Revised (PCL-R) are used to support decisions regarding personal liberty. There is increasing concern about its interrater reliability in applied contexts, where low reliabilites have been obtained. We report a study in which 12 forensic psychiatric staff raters assessed 43 male offenders for psychopathy using the PCL-R. These ratings were compared with those obtained at a second occasion from separate interviews utilizing similar file data by an independent researcher, experienced as an expert for the defense. Intraclass correlation coefficients were high; .89 for the PCL-R total scale, .82 for Factor 1, and .38 – .94 for individual items. These results stand in contrast to the considerably lower reliabilities found in recent field studies, mainly conducted within adversary judicial systems. In such contexts, ratings may be biased. Interrater reliability of PCL-R is likely be increased if raters utilize similar data.
