Abstract

Background The new programme for assessing those with dangerous and severe personality disorder relies heavily on psychological assessments of personality disorder and risk. Methods The temporal reliability of assessments of psychopathy (PCL-R), risk (HCR-20) and persoruility was assessed using the International Personality Disorder Examination (IPDE) in 15 randomly selected mak prisoners in a high secure hospital carried out at intervals varying between a mean of nine and 19 months after initial assessments by a variety of assessors. Results Using the intra-class correlation coefficient the agreement varied between 0.57 (HCR'2O), 0.58 (PCL-R) and 0.38-0.70 for IPDE personality disorders, with the best agreement for antisocial personality disorder (0.70). Comment TKese levels of agreement are consistent with other recent work on temporal reliability of personality instruments but are a little too low for confidence in these measures alone in the assessment process.
