Abstract

Risk assessment is an important aspect of forensic psychiatric care. The IFTE is a tool used for treatment evaluation, consisting of items derived from the HKT-R. While IFTE-items are similar to the clinical items of the HKT-R, the IFTE is less time consuming and possibly less bias-producing. Both instruments can be used in predicting short-term intramural violence. If the IFTE could replace the clinical items of the HKT-R, risk assessment has a higher cost- efficiency. This study explores whether the IFTE scores are comparable to the HKT-R scores and if the IFTE is a better or comparable predictor of short-term intramural violence compared to the clinical items of the HKT-R. Subsequently, this study researches which individual items of both instruments can distinguish best between who does and who does not commit short-term intramural violence. To find out which instrument has the best predictive value in the case of intramural violence, binary logistic regressions were performed with data of 50 patients of Forensic Psychiatric Centre Dr. S. van Mesdag. The sum of rounded mean IFTE-scores turned out to have a significant predictive value for intramural violence, the sum of rounded maximum IFTE-scores and the HKT-R-scores did not. The likelihood ratio ꭓ2 analysis showed that for the HKT-R-scores ‘antisocial behavior’ and for the sum of rounded mean IFTE-scores ‘hostile behavior’ distinguished best between persons who do and do not commit violence. Conclusion of this study is that the IFTE cannot yet replace the clinical items of the HKT-R. This might be due to the relatively small sample size and methodological limitations in the current study.
