Abstract

Background Although Dutch forensic psychiatry is making increasing use of structural risk assessment scales, the controversy about the value and usefulness of these instruments continues unabated. aim To provide an overview of the psychometric qualities of the instruments used most often in the Netherlands for risk assessment in adults. Method Dutch data about the Historical, Clinical, and Risk Management (hcr-20), the Sexual Violence Risk-20 (svr-20), the Psychopathy Checklist-Revised (pcl-r) and two Dutch instruments, the ‘Historische, Klinische en Toekomstige Risico-indicatoren-30’ (hkt-30) and the ‘Forensisch Psychiatrische Profielen’ (fp-40) were reviewed. In addition, data relating to the unstructured clinical judgment were studied. Results The inter-rater reliability values of the instruments discussed were in general satisfactory, but the internal consistency was often unsatisfactory. Except in some studies, the predictive validity was in general reasonable. Conclusion At present, caution is called for with regard to the assessment of the risk of recidivism when this is based purely on risk assessment scales or purely on the unstructured judgment. Perhaps it is simply not possible to predict recidivism more accurately. Until there are some new developments in this area, it seems advisable to combine as many data as possible about a person under investigation derived from assessment scales and clinical judgment and to compare the outcome with the conclusions of the other professionals.
