| Abstract: | In this study, the relationship between psychopathy, according to the Dutch language version of Hare's Psychopathy Checklist-Revised (PCL-R), and various types of disruptive behavior during inpatient forensic psychiatric treatment is investigated. Ninety-two male participants were administered the PCL-R following admission to an inpatient forensic hospital. From daily hospital information bulletins, incidents of verbal abuse, verbal threat, physical violence, and violation of hospital rules were derived. Also, the number of seclusion episodes was recorded. As expected, significant correlations were found between PCL-R scores and verbal abuse, verbal threat, violation of rules, total number of incidents, and frequency of seclusion. Psychopaths (PCL-R > or = 30) were significantly more often involved in incidents than nonpsychopaths. Multiple regression analyses revealed that the PCL-R Factor 2 score in particular contributed uniquely to the prediction of the total number of incidents. The findings are discussed in terms of their clinical implications. |
